In which three situations will a Smart Scan occur on a table for which Smart Scan is possible, assuming that nothing in the environment prevents a Smart Scan?


  1. The ASM diskgroup containing the table’s tablespace has a 4 MByte AU size.

  2. Executing queries in parallel.

  3. setting serial_direct_read= true in the session issuing the SQL statements and executing a serial query.

  4. Having direct path reads used at execution time.

  5. An update to the table is made identifying the row to be modified by primary key.

  6. An index range scan occurs for the table.


Answer: B, C, D


Explanation:

Whether you get a direct path read & smart scan, depends on the current buffer cache size, how big segment you’re about to scan and how much of that segment is actually cached at the moment. This dynamic decision unfortunately can cause unexpected surprises and variance in your report/batch job runtimes.

To work around these problems and force a direct path read/smart scan, you can either: D: One of the most common Exadata performance problems is that the direct path reads (and thus also Smart Scans) don’t sometimes kick in when running full scans in serial sessions. Note: Smart Scan is a subset of Cell Offload Processing and is perhaps the feature that is most highly associated with Exadata. Smart Scan allows Oracle databases

to push query information down to the storage level, specifically:


QUESTION: 83

Which three statements are true concerning InfiniBand port and subnet monitoring on an X5 Database Machine?


  1. The Infiniband subnet master location can be determined by using the getmaster command run on any database server.

  2. The Infiniband subnet master location can be determined by using the getmaster command run on an IB switch.

  3. The InfiniBand port status may be displayed on the storage servers by using the LIST IBPORT command in the CELLCLI utility.

  4. The InfiniBand port status may be displayed on the Infiniband switches by using the LIST IBPORT command in the DBMCLI utility.

  5. The InfiniBand port status may be displayed on the database servers by using the LIST IBPORT command in the DBMCLI utility.

  6. The InfiniBand port monitoring is automatic on the database servers and is managed by Enterprise Manager.


Answer: B, C, E


Explanation:

B: From any InfiniBand switch in the network (leaf switch or spine switch), log in as root and run the getmaster command to obtain the location of the master SM as follows:

# getmaster

This command displays the host name or IP address and the IP address of the switch where the master SM is running. C: CellCLI> list ibport - Will display InfiniBand configuration details

E: The DBMCLI utility is the command-line administration tool for configuring database servers, and managing objects in the server environment.

The LIST IBPORT command displays attributes for InfiniBand ports determined by the specified attributes and filters.

QUESTION: 84

Which two are true about the allocation of I/O resources by IORM within the CELLSRV process?


  1. Database Writer I/O always prioritized over all user I/O.

  2. If two consumer groups P and Q in the PROD database get 20% and 10% respectively of resource allocation, then the percentage of I/O resource would be the same if they got 10% and 5% respectively, and the interdatabase plan has changed, provided that the category plan is unchanged, and consumer groups P and Q are still mapped to the same categories.

  3. If two consumer groups C and D in the PROD database get 10% and 15% respectively, of resource allocation, then the percentage of I/O resource would be the same if they still got 10% and 15% respectively, and were remapped to a different category by the DBA, provided that the category plans and the interdatabase plans are unchanged.

  4. If two consumer groups A and B in the PROD database get 10% and 15% respectively, of resource allocation, then the percentage of I/O resource would be the same if they got 20% and 30% respectively, provided that the category plans and interdatabase plans are unchanged, and consumer groups A and B are still mapped to the

    same category.

  5. Log Writer I/O and Control File I/O are always prioritized over all user I/O.


Answer: B, E


Explanation:

B: Rules in an interdatabase resource plan specify allocations to databases, not consumer groups. E: Redo and control file writes always take precedence.


QUESTION: 85

Which two completely prevent a Smart Scan from occurring?


  1. querying a table containing many chained rows

  2. querying a table containing many migrated rows

  3. performing a minimum or maximum function on an indexed column

  4. performing a Fast Full Index scan on a reverse key index

  5. referencing more than 255 columns form an OLTP compressed table in a query

  6. querying a table containing a JSON column


Answer: B, E


Explanation:

B: Migrated Rows is a special case of chained rows. Migrated rows still affect

performance, as they do in conventional storage situations, but with the additional overhead of reducing the beneficial effects of “Smart Scan” in addition to increasing the number of I/Os

E: Smart Scans - broadly speaking and ignoring edge cases - can only transport a maximum columns from a single (non- HCC) segment. Requesting more columns will simply disable Smart Scans for that segment.

An interesting limitation to Exadata Smart Scans - if more than 254 columns from a table (not HCC compressed, more on that in moment) need to be projected, Smart Scans for that particular segment will be disabled and Exadata will fall back to conventional I/O. This means that the number of columns in the projection clause can make a significant difference to performance, since only Smart Scans allow taking advantage of offloading and particularly avoiding I/O via Storage Indexes.


QUESTION: 86

You wish to determine if the I/O resource management plan that you created has helped improve the performance of OLTP category I/Os on your X6 Exadata Database

Machine. You decide to examine the relevant metrics on all the cells, to see whether the I/O rate has improved for this category compared to last week, and whether waits and wait time have been reduced. You issue this command on the first cell:


image


You examine the output from the first cell which contains:


image


Which two sets of metrics would you use to determine whether the I/O performance has improved for the OLTP category for the duration of the one-hour measurement period?


  1. CT_IO_RQ_SM, CT_IO_RQ_LG, CT_IO_RQ_SM_SEC, and CT_IO_RQ_LG_SEC

  2. CT_IO_UTIL_SM and CT_IO_UTIL_LG

  3. CT_IO_RQ_SM_SEC and CT_IO_RQ_LG_SEC

  4. CT_IO_WT_SM, CT_IO_WT_LG, CT_IO_WT_SM_RQ, and CT_IO_WT_LG_RQ


Answer: D

QUESTION: 88

Which three statements are true about Exadata storage server alerts in an X5 Database Machine?


  1. Storage server alerts notifications may be sent using SNMP.

  2. A threshold- based alert gets cleared automatically when the measured value no longer violates the threshold.

  3. A storage server alert is only ever issued as a warning or at a critical situation.

  4. Storage server alerts are all stateless alerts.

  5. Storage server alerts are all stateful alerts.

  6. Storage server alerts notifications may be sent using SMTP.


Answer: A, C, F


Explanation:

Exadata cell (storage server) alerts can be delivered using SMTP or SNMP or both. Although there are three types of storage alerts: informational, warning and critical, they are issued when threshold metrics reached either to warning or critical.


QUESTION: 89

Which two statements are true about RMAN incremental level-1 backups for a database running on an X5 Database Machine?

  1. Block Change tracking (BCT) is not needed for databases in an X5 Database Machine, because ASM automatically does block change tracking when diskgroups are built from griddisks.

  2. cellsrv filters blocks and returns only those that have changed since the last backup, for databases in archivelog mode.

  3. cellsrv returns all blocks that have been or might have been changed since the last backup, and RMAN filters the blocks that do not require backup.

  4. cellsrv filters blocks and returns only those that have changed since the last backup, for databases in noarchivelog mode.

  5. Block Change Tracking (BCT) is not needed for databases in an X5 Database Machine, because change tracking is done by cellsrv.


Answer: D, E


Explanation:

D: Whenever data blocks change, the Change Tracking Writer (CTWR) background process tracks the changed blocks in a private area of memory.

When RMAN performs an incremental backup on the Exadata platform, cellsrv filters out unwanted blocks and sends back only those that have changed since the last level 0 or level 1 backup.

E: For the Exadata platform, you may choose to allow cellserv to do all the blocking filtering for incremental backups. Note: RMAN block change tracking is used to improve the performance of incremental backup. The level 0 incremental backup scans the entire database but level 1 incremental backups use the block change tracking file to scan only the blocks that have changed since the last backup. This significantly reduces

the amount of reads that are required on the database.

QUESTION: 90

Which two statements are true regarding the use of Auto Service Request (ASR) with an X6 Database Machine?


  1. The database server ILOMs must use SMTP over the management network for notifications to ASR Manager.

  2. The database server ILOMs must have SNMP traps configured to use the management network for notifications to ASR Manager.

  3. The storage server ILOMs must have SNMP traps configured to use the management network for notifications to ASR Manager.

  4. The database server MS process must have SNMP traps configured to use the

management network for notifications to ASR Manager.


Answer: B, C


Explanation:

B: Database Server ILOM plug-in

Monitoring databases and their instances, ASM environments, the Grid Infrastructure, and the host software environment are done by Enterprise Manager in the usual way as these are standard targets. But monitoring the hardware for the database servers requires the ILOM plug-in, as there is no Management Server (MS) on the database servers to receive SNMP traps from the ILOM. The plug-in will receive sensor state and availability data from the ILOM including alerts based on pre-set ILOM thresholds.

C: Exadata Storage Server plug-inextends the monitoring of exadata cells in addition to providing a GUI interface. The plug-in uses an SSH connection to the cellmonitor user on the cells and uses list commands only. This is for interactive monitoring. One may also set thresholds using the plug-in which are distinct from any thresholds set using cellcli utility as the celladmin user. For alerts to be sent to the plug-in, SNMP traps are used as follows:

Cell ILOM alerts are sent to the cell Management Server (MS) via an SNMP trap. The MS then send SNMP notifications onward to the plug-in.

Cell alerts flagged by MS itself, such as cell thresholds being exceeded, or ADR software alerts, are sent to the plug-in using SNMP.

An Exadata Primer | 1Z0-070 Real Questions and VCE Practice Test In 2008 Oracle added Exadata, and facts warehousing, business intelligence and OLTP purposes have benefited from this built-in know-how stack. Exadata isn't like anything else most DBAs have ever considered or managed; it's a tuned combination of database server, storage server and personal interconnects that really can outperform commodity hardware configurations. Let's take a peek internal Exadata and get a glimpse of what Oracle hath wrought. An Exadata computing device is greater than simply the components that include it. In its smallest configuration the rack homes two database servers operating Oracle enterprise Linux, a storage server managing storage 'cells' (operating its working system referred to as 'cellsrv') and a non-public interconnect referred to as InfiniBAND to allow the database servers to talk, albeit in a roundabout way, to the storage server. customarily during this configuration the raw storage provides up to 104 terabytes, and or not it's configured with commonplace redundancy providing, all instructed, fifty two terabytes of storage. Accounting for the operating gadget and different management software the usable storage runs round 39 TB divided among diskgroups earmarked for database storage, recovery and an interesting function known as DBFS (more on that later). How does all of this hardware, application, memory and storage work together? fairly properly as Oracle has performed a superb job of creating a database appliance that may dramatically enrich efficiency over prevalent setups. Exadata is built to successfully use the elements to return effects to the conclusion person. toward that end it has been designed to dump query initiatives to the storage server, when feasible, to cut back the volume of records passed to the calling session. certain standards should be met to dump to the storage server: Full table or index scans need to be used Direct route reads should be used to entry the records If the primary requirement isn't met an additional option can set off the offloading mechanism: Parallel query, via default, makes use of direct route reads so although full scans are not used offloading can happen. what's offloading? Exadata is wise adequate to grasp that some operations will also be transferred to the storage server and serviced via the cells at once resulting in a long way less statistics traversing the InfiniBAND 'pipe'. Offloading itself would not try this, it be what Exadata does with the offloaded projects that makes the difference. Offloading triggers a brand new execution route element known as sensible Scans, which use a further new item, Storage Indexes. Storage indexes are created in reminiscence (so that they're resident so long as cellsrv isn't restarted) and may contain as much as eight columns per storage phase. For Storage Indexes the storage cells are divided into segments of 1 MB and each section has its own Storage Index. This configuration makes it possible for Exadata to create Storage Indexes such that on one section eight columns of table A are listed, on the subsequent phase 8 columns of table B are indexed, on the next segment 8 different columns from desk A are listed, and so forth. each and every storage index information the bottom and highest values from each and every column within the index, and also comprises NULL values. Indexing NULLs offers Storage Indexes their actual energy, as these don't seem to be 'where do I find this cost' indexes as ordinary B-Tree indexes are. Storage indexes are used to inform Exadata where to no longer search for data; Exadata will bypass over storage segments that don't have any possibility of containing the desired values and this dramatically speeds searches and statistics retrieval. If a smart Scan is effected it could actually return statistics in mere seconds in preference to the minutes it may take the usage of a standard database configuration (database server, swap, community storage array); bear in mind, though, that no longer all queries submitted to Exadata will qualify for smart Scans. That being the case, the built-in design of the Exadata machine enables it to outperform everyday setups in most cases, with or devoid of using a wise Scan. How do you know you've gotten used a sensible Scan? The 'telephone sensible table scan' wait experience or the 'mobile smart index scan' wait experience will reveal undertaking indicating a wise Scan came about. Nothing in the execution plan can be displayed to prove a smart Scan become used; querying v$waitstat may be the best method to ascertain that a sensible Scan was applied. a further unique factor of Exadata is that the database servers don't have any direct entry to the storage cells. ASM is configured to be the bridge between the database and storage servers. The storage server has its own operating system and Oracle database, which is how smart Scans are done. all the add-ons are integrated, which can be a problem for corporations that separate UNIX/Linux equipment administration duties, Oracle DBA obligations, network configuration and storage duties as patching and protection for the Exadata machine is performed the use of bundles that make sure no utility/firmware mismatches take place. Such mismatches may influence in Exadata points now not working safely or, at the worst case, failing to work in any respect. Oracle suggests a new function, the DMA (Database laptop Administrator) that has both Oracle admin rights and O/S admin rights (root) in order that patching may also be carried out and proven by using personnel expert in Exadata computing device management. it is possible to divide the obligations supplied there is first rate verbal exchange between the companies right through upkeep outages. Getting lower back to parallel query there is a new method, in 11.2, to manipulate parallel executions throughout periods, which is extremely valuable within the Exadata ambiance -- parallel remark queuing. This works in concert with one more new characteristic, Auto diploma of Parallelism, that could dynamically reconfigure the parallelism right through query execution. Auto DOP is managed by means of the parallel_degree_policy parameter and when set to auto will put into effect auto DOP. No objects need to have diploma set as Oracle will determine, at run time, the most efficient DOP for the query offered it's going to take longer than parallel_min_time_threshold, which defaults to 10 seconds. (As general this parameter can even be set to a different value to permit greater, or fewer, queries to run in parallel.) Oracle additionally provides some measure of handle on how it determines the top-rated DOP with the parallel_degree_limit parameter, which defaults to CPU however will also be set to CPU, IO, AUTO or an integer cost. None of this could work on eleven.2 if I/O calibration has not been achieved. here's accomplished with the DBMS_RESOURCE_MANAGER.CALIBRATE_IO manner; it takes two IN parameters, the number of disks and the optimum disk latency, and three OUT parameters, placeholders for latency, optimum i/o per 2nd and the optimum MB per 2d. The manner can take as long as 15 minutes to run as it generates a random workload spread across all nodes within the RAC cluster. as soon as accomplished Auto DOP can be enabled and will feature as expected. If the calibration has now not been finished then Oracle will skip Auto DOP and document in the execution plan that the IO calibrate data are missing. Getting again to parallel commentary queuing as soon as parallel_degree_policy is decided to auto and parallel_servers_target is decided to a 'low-cost' price ('competitively priced' meaning the preferred optimum variety of parallel servers you wish to have operating at one time) you are able to go. Queries will run the use of Auto DOP until the equipment hits the limit you set with parallel_servers_target at which era the ultimate queries will be queued until supplies (parallel question slaves) are available. by using default it's a primary In / First Out queue -- this conduct will also be modified but I won't cowl that listed here. As slaves are made available via prior queries finishing, the next query in line is run and this continues until the gadget has freed adequate supplies to run the final queries in the queue or the queue comes to end. Monitoring the queue progress is relatively basic as the counsel is found in the V$SQL_MONITOR view; if the popularity is QUEUED then the question is anticipating components to be made obtainable. V$PX_PROCESS_SYSSTAT can report what number of slaves are in use; the use of both views will enable you to assess which queries are queued and when the subsequent query will come out of the queue to be done. there is so a whole lot extra to Exadata, greater than can be put right into a single article, which is why there are several books on the discipline. (My own alternative is "knowledgeable Oracle Exadata", from Apress, written by Kerry Osborne, Randy Johnson and Tanel Poder.) The intent of this text is to provide a place to begin for the journey into Exadata via discussing one of the most aspects and, well, wonders, of the Exadata computing device and i hope my efforts have been successful. i'm currently on a undertaking where a consumer is migrating Oracle ERP databases to Exadata and that i'm discovering new areas of Exadata day by day, and enjoying it immensely. where once Exadata became a novelty it be now a proven expertise, carried out by many companies world-large. at some point soon it will probably come to you (if it hasn't already); what I've lined right here should put together you to your first experience with Exadata.

Perhaps best known for its premier database software, the company also offers cloud solutions, servers, engineered systems, storage and more. Oracle has more than 430,000 customers in 175 countries, about 138,000 employees and exceeds $37.7 billion in revenue. Over the years, Oracle has developed an extensive certification program. Today, it includes six certification levels that span nine different categories with more than 200 individual credentials. Considering the depth and breadth of this program, and the number of Oracle customers, it's no surprise that Oracle certifications are highly sought after. Oracle certification program overview Oracle's certification program is divided into these nine primary categories: Oracle Applications Oracle Cloud Oracle Database Oracle Enterprise Management Oracle Industries Oracle Java and Middleware Oracle Operating Systems Oracle Systems Oracle Virtualization Additionally, Oracle's credentials are offered at six certification levels: Junior Associate Associate Professional Master Expert Specialist Most Oracle certification exams are proctored, cost $245, and contain a mix of scored and unscored multiple-choice questions. Candidates may take proctored exams at Pearson VUE, although some exams are offered at Oracle Testing Centers in certain locations. Some exams, such as Oracle Database 12c: SQL Fundamentals (1Z0-061) and Oracle Database 11g: SQL Fundamentals (1Z0-051), are also available non-proctored and may be taken online. Non-proctored exams cost $125. Check the Oracle University Certification website for details on specific exams. Oracle Applications and Cloud certifications The Oracle Applications certification category offers more than 60 individual credentials across 13 products or product groups, such as Siebel, E-Business Suite, Hyperion, JD Edwards EnterpriseOne and PeopleSoft. The majority of these certifications confer Certified Implementation Specialist for some specific application, with various Certified Expert credentials also available. The Application certifications aim at individuals with expertise in selling and implementing specific Oracle solutions. Oracle's newest certification category is Oracle Cloud, which covers Java Cloud as well as a number of Oracle Cloud certifications, including Oracle Database Cloud. Cloud certs fall into seven sub-categories: Infrastructure as a Service (IaaS) Platform as a Service (PaaS), including Data Management, Application Development, Management Cloud and Mobile Cloud Service Software as a Service (SaaS) Oracle Customer Experience Cloud, including Service, Sales, Marketing and CPQ Cloud Software as a Service Oracle Performance Management Cloud, including Performance Reporting, Enterprise Planning and Budgeting, Financial Consolidation and Close, Profitability and Cost Management Cloud Software as a Services Oracle Enterprise Resource Planning Cloud, including Financials, Project Portfolio Management, Procurement and Risk Management Cloud Software as a Service Oracle Human Capital Management Cloud, including Workforce Rewards, Payroll, Talent Management and Global Human Resources Cloud Software as a Service Oracle Supply Chain Management Cloud, including Order Management, Product Master Data Management, Product Lifecycle Management, Manufacturing, Inventory Management, Supply Chain Planning and Logistics Cloud These credentials recognize individuals who deploy applications, perform administration or deliver customer solutions in the cloud. Credentials mostly include Associate and Certification Implementation Specialists, with one Mobile Developer credential offered plus a professional-level Oracle Database Cloud Administrator. Oracle Database certifications Certifications in Oracle's Database category are geared toward individuals who develop or work with Oracle databases. There are three main categories: Database Application Development, MySQL and Oracle Database. Note: Oracle Database 12c was redesigned for cloud computing (and is included in both the Cloud and Database certification categories). The current version is Oracle Database 12c R2, which contains additional enhancements for in-memory databases and multitenant architectures. MySQL 5.6 has been optimized for performance and storage, so it can handle bigger data sets. Whenever a significant version of either database is released, Oracle updates its certifications exams over time. If an exam isn't available for the latest release, candidates can take a previous version of the exam and then an updated exam when it becomes available. Though MySQL 5.6 certifications and exams are still available for candidates supporting that version, the new MySQL 5.7 certification track may be more appropriate for those just starting on their MySQL certification journeys. Oracle currently offers the Oracle Database Foundations Certified Junior Associate, Oracle Certified Associate (OCA), Oracle Certified Professional (OCP), Oracle Certified Master (OCM), Oracle Certified Expert (OCE) and Specialist paths for Oracle Database 12c. In addition, Oracle offers the OCA credential for Oracle Database 12c R2 and an upgrade path for the OCP credential. Because many of these certifications are also popular within the Oracle Certification Program, we provide additional exam details and links in the following sections. Other database certifications Oracle Enterprise Management Certifications The Oracle Enterprise Manager Certification path offers candidates the opportunity to demonstrate their skills in application, middleware, database and storage management. The Oracle Enterprise Manager 12c Certified Implementation Specialist exam (1Z0-457) certifies a candidate's expertise in physical, virtual and cloud environments, as well as design, installation, implementation, reporting, and support of Oracle Enterprise Manager. Oracle Database Foundations Certified Junior Associate The Oracle Database Foundation Certified Junior Associate credential targets those who've participated in the Oracle Academy through a college or university program, computer science and database teachers, and individuals studying databases and computer science. As a novice-level credential, the Certified Junior Associate is intended for individuals with limited hands-on experience working on Oracle Database products. To earn this credential, candidates must pass the Oracle Database Foundations (novice-level exam) (1Z0-006). Oracle Certified Associate (OCA) Oracle Database 12c Administrator The OCA certification measures the day-to-day operational management database skills of DBAs. Candidates must pass a SQL exam and another on Oracle Database administration. Candidates can choose one of the following SQL exams: Oracle Database 12c SQL (1Z0-071) Oracle Database 12c: SQL Fundamentals (1Z0-061) NOTE: This exam will be retired on November 30, 2019. Candidates must also pass the Oracle Database 12c: Installation and Administration (1Z0-062) exam. Oracle Certified Associate Oracle Database 12cR2 Administrator To earn the Oracle Database 12cR2 OCA credential, candidates must first earn either the Oracle Database SQL Certified Associate, Oracle Database 11g Administrator Certified Associate, or the Oracle Database 12c Administrator Certified Associate. In addition, candidates are required to pass the Oracle Database 12cR2 Administration exam (1Z0-072). Oracle Certified Professional (OCP) Oracle Database 12c Administrator The OCP certification covers more advanced database skills. You must have the OCA Database 12c Administrator certification, complete the required training, submit a course submission form and pass the Oracle Database 12c: Advanced Administration (1Z0-063) exam. Professionals who possess either the Oracle Database 11g Administrator Certified Professional or Oracle Database 12c Administrator Certified Professional credential may upgrade to the Oracle Database 12cR2 Administration Certified Professional credential by passing the Oracle DBA upgrade exam (1Z0-074). Oracle Certified Master (OCM) Oracle Database 12c Administrator To achieve OCM Database 12c Administrator certification, you must have the OCP Database 12c Administrator certification, complete two advanced courses, and pass the Oracle Database 12c Certified Master Exam (12cOCM), complete the course submission form, and submit the Fulfillment Kit request. Oracle also offers the Oracle Database 12c Maximum Availability Certified Master certification, which requires three separate credentials, including the Oracle Database 12c Administrator Certified Master, Oracle Certified Expert, Oracle Database 12c-RAC and Grid Infrastructure Administration, and Oracle Certified Expert, Oracle Database 12c Data Guard Administration. Oracle Certified Expert (OCE) Oracle Database 12c The OCE Database 12c certifications include Maximum Availability, Data Guard Administrator, RAC and Grid Infrastructure Administrator, and Performance Management and Tuning credentials. All these certifications involve prerequisite certifications. Performance Management and Tuning takes the OSP Database 12c as a prerequisite and the Data Guard Administrator certification requires the OCP Database 12c credential. The RAC and Grid Infrastructure Administrator provides candidates the most flexibility, allowing candidates to choose from the OCP Database 11g, OCP Databases 12c, Oracle Certified Expert Real Application Clusters 11g and Grid Infrastructure Administration. Once the prerequisite credentials are earned, candidates can then achieve Data Guard Administrator, RAC and Grid Infrastructure Administrator or Performance Management and Tuning by passing one exam. Achieving OCP 12c plus the RAC and Grid Infrastructure Administration and Data Guard Administration certifications earns the Maximum Availability credential. Oracle Database Certified Implementation Specialist Oracle also offers three Certified Implementation Specialist credentials: the Oracle Real Application Clusters 12c, Oracle Database Performance and Tuning 2015, and Oracle Database 12c. Specialist credentials target individuals with a background in selling and implementing Oracle solutions. Each of these credentials requires candidates to pass a single exam to earn the designation. Oracle Industries certifications Oracle Industries is another sizable category, with more than 25 individual certifications focused on Oracle software for the construction and engineering, communications, health sciences, insurance, tax and utilities industries. All these certifications recognize Certified Implementation Specialists for the various Oracle industry products, which means they identify individuals proficient in implementing and selling industry-specific Oracle software. Oracle Java and Middleware Certifications The Java and Middleware certifications span several subcategories, such as Business Intelligence, Application Server, Cloud Application, Data Integration, Identity Management, Mobile, Java, Oracle Fusion Middleware Development Tools and more. Java and Middleware credentials represent all levels of the Oracle Certification Program Associate, Professional and so on and include Java Developer, Java Programmer, System Administrator, Architect and Implementation Specialist. The highly popular Java category has certifications for Java SE (Standard Edition), and Java EE (Enterprise Edition) and Web Services. Several Java certifications that require a prior certification accept either the corresponding Sun or Oracle credential. Oracle Operating Systems certifications The Oracle Operating Systems certifications include Linux and Solaris. These certifications are geared toward administrators and implementation specialists. The Linux 6 certifications include OCA and OCP Linux 6 System Administrator certifications, as well as an Oracle Linux Certified Implementation Specialist certification. The Linux 6 Specialist is geared to partners but is open to all candidates. Both the Linux OCA and Specialist credentials require a single exam. To achieve the OCP, candidates must first earn either the OCA Linux 5 or 6 System Administrator or OCA Linux Administrator (now retired) credential, plus pass an exam. The Solaris 11 certifications include the OCA and OCP System Administrator certifications plus an Oracle Solaris 11 Installation and Configuration Certified Implementation Specialist certification. The OCA and OCP Solaris 11 System Administrator certifications identify Oracle Solaris 11 administrators who have a fundamental knowledge of and base-level skills with the UNIX operating system, commands, and utilities. As indicated by its name, the Implementation Specialist cert identifies intermediate-level implementation team members who install and configure Oracle Solaris 11. Oracle Systems certifications Oracle Systems certifications include Engineered Systems (Big Data Appliance, Exadata, Exalogic Elastic Cloud, Exalytics, and Private Cloud Appliance), Servers (Fujitsu and SPARC) and Storage (Oracle ZFS, Pillar Axiom, Tape Storage, Flash Storage System). Most of these certifications aim at individuals who sell and implement one of the specific solutions. The Exadata certification subcategory also includes Oracle Exadata X3, X4 and X5 Expert Administrator certifications for individuals who administer, configure, patch, and monitor the Oracle Exadata Database Machine platform. Oracle Virtualization certifications The Virtualization certifications cover Oracle Virtual Machine (VM) Server for X86. This credential is based on Oracle VM 3.0 for X86, and recognizes individuals who sell and implement Oracle VM solutions. The Oracle VM 3.0 for x86 Certified Implementation Specialist Certification aim at intermediate-level team members proficient in installing OVM 3.0 Server and OVM 3.0 Manager components, discovering OVM Servers, configuring network and storage repositories and more. Related jobs and careers The sheer breadth and depth of Oracle's certification program creates ample opportunities for professionals who want to work with Oracle technologies, or who already do and want their skills recognized and validated. Although there are many specific Oracle products in which to specialize in varying capacities, the main job roles include administrators, architects, programmers/developers and implementation specialists. Every company that runs Oracle Database, Oracle Cloud, or Oracle Linux or Solaris needs qualified administrators to deploy, maintain, monitor and troubleshoot these solutions. These same companies also need architects to plan and design solutions that meet business needs and are appropriate for the specific environments in which they're deployed, indicating that the opportunities for career advancement in Oracle technologies are abundant. Job listings and hiring data indicate that programmers and developers continue to be highly sought-after in the IT world. Programming and development skills are some of the most sought-after by hiring managers in 2019, and database administration isn't far behind. A quick search on Indeed results in almost 12,000 hits for "Oracle developer," which is a great indication of both need and opportunity. Not only do developers create and modify Oracle software, they often must know how to design software from the ground up, package products, import data, write scripts and develop reports. And, of course, Oracle and its partners will always need implementation specialists to sell and deploy the company's solutions. This role is typically responsible for tasks that must be successfully accomplished to get a solution up and running in a client's environment, from creating a project plan and schedule, to configuring and customizing a system to match client specifications. Oracle training and resources It's not surprising that Oracle has an extensive library of exam preparation materials. Check the Oracle University website (education.oracle.com) for hands-on instructor-led training, virtual courses, training on demand, exam preparation seminars, practice exams and other training resources. A candidate's best bet, however, is to first choose a certification path and then follow the links on the Oracle website to the required exam(s). If training is recommended or additional resources are available for a particular exam, Oracle lists them on the exam page. Another great resource is the Oracle Learning Paths webpage, which provides a lengthy list of Oracle product-related job roles and their recommended courses.

To support Oracle Linux, the company offers the Oracle Linux System Administrator certification at Associate and Professional levels. A single Oracle Linux Certified Implementation Specialist credential is also offered. We focus on the Oracle Certified Professional (OCP) version in this section. The OCP Oracle Linux System Administrator certification, currently at version 6 (although version 7 should be coming soon), covers a lot of details. Candidates must be well-versed on the Btrfs file system, control groups, Linux containers, advanced storage administration techniques, Oracle cluster management and package management. The certification also tests for knowledge of dump analysis, dynamic tracing, network and security configuration and more. The OCP Oracle Linux System Administrator certification requires that candidates first obtain the Oracle Certified Associate (OCA) Oracle Linux 5 and 6 System Administrator certification and pass one exam. SysAdmins who support Oracle Solaris might be interested in the Oracle Solaris System Administrator certification, which Oracle offers at the Associate and Professional levels. Oracle also offers several server-related certifications for SPARC and Fujitsu servers. Oracle Linux System Administrator Facts and Figures RHCE: Red Hat Certified Engineer In the realm of Linux system administrator certifications, Red Hat certs really stand out. Red Hat's more senior-level certifications are especially popular among IT professionals as well as the employers who hire them. Those holding the Red Hat Certified Engineer (RHCE) credential qualify for job roles such as senior Linux administrator, senior UNIX administrator, senior systems engineer, infrastructure systems engineer, IT analyst and the like. The RHCE is regarded as a high-level credential that's not easy to obtain. Candidates must first obtain the Red Hat Certified System Administrator (RHCSA) credential and then pass a three and a half hour, hands-on, performance-based exam that's intense and demanding. Those who earn the RHCE can go on to earn the Red Hat Certified Architect (RHCA) in Infrastructure credential. The current RHCE exam is based on Red Hat Enterprise Linux (RHEL) 7. RHCE certification is valid for three years from the date the certification was achieved. To maintain the certification, a credential holder must pass any RHCA exam or pass the RHCE certification exam again before the end of the three-year period. Note: In October 2018, IBM announced that it was acquiring Red Hat for the princely sum of $34 billion. It's too early to tell what impact this may have on Red Hat certification offerings, if any.

CompTIA Server+ CompTIA offers a long list of entry-level certifications, such as the A+ for hardware technicians, Network+ for network admins and Security+ for security specialists, all of which are highly regarded in the computing industry. The CompTIA Server+ certification is no exception. Companies such as Intel, HP, Dell, Lenovo, Xerox and Microsoft, as well as the U.S. Department of Defense, recommend or require that their server technicians earn CompTIA Server+. The Server+ certification exam focuses on foundational server-related topics that are vendor-neutral in nature, including server hardware, operating systems, storage systems, networking, the IT environment (documentation, diagrams and best practices), security and disaster recovery, virtualization and troubleshooting. The Server+ credential, along with sufficient experience, is a great asset for individuals seeking a position as a server or network administrator, systems engineer or website administrator. You can also consider it as a stepping stone to a more focused certification, such as the Microsoft Certified Solutions Associate (MCSA) or the Red Hat Certified System Administrator (RHCSA).

VCP6-DCV: VMware Certified Professional 6 - Data Center Virtualization The VMware family of certifications are must-have credentials for IT professionals interested in the field of virtualization. Offering a comprehensive certification program that encompasses all skills levels, VMware credentials are recognized globally as best in class. The latest incarnation of the VMware vSphere product is Version 6.5. VMware currently offers two credentials which target vSphere V6.5 users: the VMware Certified Professional 6.5 Data Center Virtualization and the VMware Certified Advanced Professional 6.5 Data Center Virtualization (Design and Deploy). It's anticipated that the VMware Certified Design Expert (VCDX-DCV) will be available soon. Although Version 6.5 is the newest version of the vSphere product, interested candidates can still certify on vSphere V. 6. The VMware Certified Professional 6 - Data Center Virtualization (VCP6-DCV) is one of VMware's most popular credentials with more than 100,000 certified credential holders. The VCP6-DCV prepares credential holders for more advanced certifications, including the VMware Certified Advanced Professional (VCAP6-DCV) and the pinnacle cert, VMware Certified Design Expert (VCDX-DCV). For this article, we chose to concentrate on the requirements for the VCP6.5 DCV since it's based on the newest version of vSphere. Training is required for non-credential holders seeking to obtain the VCP6-DCV. VMware offers a variety of training options to meet the training prerequisite: self-paced (on demand), live online and live classroom, some of which include virtual labs. Those possessing a valid VCP5-DCV or VCP6-DCV credential need only pass a delta exam to obtain the credential.

Beyond the Top 5: More SysAdmin Certifications Beyond the five system administrator certifications featured in this article, there are many other certification programs that can help to further the careers and professional development of IT professionals who work in system administration. It makes sense to investigate the plethora of vendor-specific programs available for those who work with systems from companies such as Brocade, Dell EMC, HPE, IBM, NetApp, Symantec and so forth. Many of them play into key system specialty areas, such as storage, security or virtualization, while others offer a broad range of platforms for these and other technology areas. Here are some examples: IBM Certified System Administrator (and Advanced Administrator), for WebSphere Application Server Network Deployment, AIX, DB2, Connections, Sametime, Lotus Notes, Informix, IBM i and more NetApp Certified Data Administrator (NCDA), geared toward professionals who manage NetApp data storage controllers running the ONTAP operating system ServiceNow Certified System Administrator, aimed at professionals who are adept at configuring, implementing and managing ServiceNow systems Likewise, vendor-neutral certification programs also offer a variety of interesting and potentially valuable credentials. For example, the LPI LPIC certifications, which had been in our top five list for several years, are well known and widely recognized in IT shops and operations that depend on Linux servers to handle their workloads. It's best to think of our top five certifications as a good place to start, while also realizing that there are many other options to consider as well.
