A contemporary Oracle assist notice has some crimson Hat commercial enterprise Linux (RHEL) customers questioning about Oracle’s future champion of purple Hat. however one expert says it’s greater an announcement of Oracle’s plans for its own database storage management facets.
The notice, launched this spring and up-to-date past this month, has to result with ASMLib, a befriend library for the automatic Storage management (ASM) duty of Oracle Database. in line with the word, the befriend library “makes it feasible for an Oracle Database the usage of ASM more efficient and capable entry to the disk corporations it's using.”
One factor of the champion note issues RHEL 6, launched in the plunge and up to date remaining month.
“For RHEL6, Oracle will best deliver ASMLib software and updates when configured with a kernel distributed by Oracle,” the notice reads. “Oracle will not supply ASMLib programs for kernels disbursed by crimson Hat as fragment of RHEL6. ASMLib updates could breathe delivered by means of Unbreakable Linux community (ULN) which is purchasable to customers with Oracle Linux guide. ULN works with each Oracle Linux or red Hat Linux installations, but ASMlib utilization would require changing any purple Hat kernel with a kernel provided by means of Oracle.”
Oracle’s mixed message on ASMlibThe word has made some Oracle purchasers who elope purple Hat worried about Oracle’s intentions. Marianne Gillfillan, a database administrator with Concordia Administrative guidance gadget -- which is fragment of the St. Louis-based Concordia university gadget -- pointed out she’s involved. She wonders even if the notice talent Oracle will start forcing Oracle shops running ASM on Linux to drop purple Hat befriend for its personal.
“I result deem it’s their try and drag champion from RHEL to [Oracle Enterprise Linux],” Gillfillan spoke of.
however Tim hall isn’t so bound. corridor is an Oracle licensed skilled and runs the accustomed Oracle DBA and developer web page oracle-base.com. He spoke of that udev, a implement supervisor in the Linux kernel, has become the de facto replacement for ASMLib.
“The narrative goes that after Oracle came up with ASMLib, they deliberate on it being an API that storage vendors would travail with,” corridor pointed out. “The reality is that this didn’t ensue, so everyone ASMLib ended up doing is disk discovery, permissions and ownership. This can likewise breathe done well-nigh as quite simply with udev, which has the expertise of not needing to breathe upgraded every time the kernel version changes.”
Neither Oracle nor crimson Hat would remark for this story.
hall introduced that even early supporters of ASMLib inside Oracle own since advised there is no factor to using it now. Some writing that dates returned a brace of years additionally means that ASMLib is out of date on a latest Linux equipment.
Gillfillan talked about she hasn’t been able to ensnare an reply from Oracle or red Hat on the reasons in the back of the champion breathe aware. And though she mentioned that udev may well breathe a workable exchange, she referred to that she and other DBAs own swirl into so familiar with the usage of ASMLib that they might likewise silent swap champion to Oracle when the time comes. meanwhile, Gillfillan is planning to consider the capabilities of alternatives reminiscent of udev. in the event that they’re not up to par, she’ll stick to ASMLib and circulation to Oracle commerce Linux.
“The handiest concern I contemplate with switching is that Oracle assist has no longer been very responsive currently, as a minimum on the database side of issues,” she observed. “I’m hoping that they are just a limited more responsive on the OS [operating system] facet. otherwise it’s going to breathe a tremendous step down in help.”
corridor recounted that he is simply speculating concerning the causes behind the assist note, asserting he can not truly recognize the causes behind the flow.
“but doing away with pilot for a product that the majority americans don’t bother with and can breathe with ease changed via fairly of aboriginal functionality is hardly a obvious signal of impending doom for RHEL,” he pointed out.

Having an Oracle certification can breathe your ticket to secure future in IT. And with nearly 300 certs to select from, anesthetist you own a lot of options. Which one is prerogative for you?
Twenty years ago, the information technology certification landscape was vastly different than is the case today. The number of certification authorities in existence now is an order of magnitude greater than what existed then. In 1995, two of the credentials most likely to turbo-charge someone’s career were the Certified NetWare Engineer (CNE) and Microsoft Certified Systems Engineer (MCSE) designations.
Fast forward two decades and NetWare has essentially disappeared from the marketplace. The CNE certification silent exists in a modified format, but its weight has diminished to a tiny fraction of what was the case in the ’90s. The retooled MCSE certification suite is silent significant, but arguably does not own the very plane of mojo that it had once upon a time.
One lesson to grasp from the above is the transitory nature of everyone things related to information technology. Earning a CNE in 1992 almost invariably had a significant influence on job offers and salary, but the very cannot breathe said of earning one in 2012. Since working careers generally eventual forty-plus years, it is extremely unlikely that any given technology that someone picks at the start of their career will breathe the very one they are using when they retire.
While this is something to preserve in judgement when choosing a career, it is not really the judgement for bringing up the CNE and MCSE certifications. Instead what struck me as I started writing this article was that in 1995, these were the only two certifications that I considered pursuing. The Oracle certification program had not started. The Cisco CCIE had kicked off in 1993, but had not yet become widely known. The only CompTIA certification available was the A+ credential. There just were not very many choices.
Today there are dozens of certification authorities to select from and hundreds of potential certification tracks to follow. Individuals must (or at least should) pledge a considerable amount of time researching which one makes the most sense for them before they can begin the process of earning it. This article will not deal with the myriad certification options available in the market today. Comparing and contrasting everyone of the potential companies and technologies would grasp a novel-length presentation. Instead this article is about the Oracle certification program and presents some factors for consideration when determining whether to pursue one of the offered credentials.
Oracle as a company primarily focuses on high-end or enterprise-class solutions. Their software products watch to breathe high-performance and highly scalable tools directed at medium to big organizations. Most of their products likewise watch to breathe fairly expensive, albeit with a handful of exceptions such as Oracle Linux, MySQL, and VirtualBox.
Organizations watch to utilize Oracle software products for activities that are captious to their business. They are willing to pay a premium to own a solution that is more robust or faster or more capable than is feasible from alternate products. From a professional standpoint, I own always establish job openings for Oracle DBA and developer positions to own a higher salary scope than comparable positions for other RDBMS (relational database management system) options such as MySQL, MariaDB, or Microsoft SQL Server. In my opinion, this is fragment of the very rationale that caused the organization to select Oracle software.
When a software solution is captious to their business, companies want to hire candidates who can ensnare the best feasible results from it. The downside of that crave is that it is notoriously difficult for IT professionals with zero travail undergo to ensnare their first job working as an Oracle DBA or developer. Getting a foot in the door of an Oracle shop requires more effort. Earning an Oracle certification can breathe a factor in landing that initial position.
The Oracle certification program now offers six several types of certifications. The credentials cover a wide scope of potential candidates — from people who own never used Oracle to ones with many years of professional undergo with the database. Three of the certifications below figure a hierarchy (OCA, OCP, and OCM), while the other three (OCJA, OCE, OCS) own no relationship or dependency with any other Oracle credential.
Oracle Certified Junior Associate (OCJA) — This is a recent addition by the Oracle certification program. The OCJA exams are targeted at individuals who are very original to Oracle. The information tested is comparable to what is taught in college-level MIS and computer science courses. Note that while some people utilize the acronym OCJA to advert to the Associate plane Java certifications, the official certification for these is “Oracle Certified Associate, Java”. They are silent OCA-level credentials and are unrelated to the Oracle Certified Junior Associate designation.
Oracle Certified Associate (OCA) — These are entry-level certifications that are designed to assess knowledge of the fundamentals. OCA tests watch to cover a broad scope of topics to a shallow depth.
Oracle Certified Professional (OCP) — Most OCP credentials require passing a set of exams that summon for knowledge of material that is more advanced than the associate certifications. Tests at the OCP-level generally cover a narrower scope of topics than OCA exams and require a greater depth of knowledge to answer.
Oracle Certified Expert (OCE) — The expert exams are designed to test for a high degree of proficiency in a specific theme area. OCE certifications are earned with a unique test and cover a very narrow scope of topics to a significant depth.
Oracle Certified Specialist (OCS) — The specialist exams are designed to focus on knowledge of the features and functionality of a specific Oracle product. Less technical than the OCA/OCP/OCE/OCM certifications, these exams are largely targeted at professionals who will breathe performing the initial implementation of a product.
Oracle Certified Master (OCM) — Oracle offers Master-level exams for database administration and Java developers. The administration exam is a two-day lab exercise while the Java OCM exams require candidates to complete a programming project in Java. Both require significant undergo to pass.
One of the first preconceptions to dispense with is the thought that the Oracle certification program is only about the Oracle database. When it first started in 1998, Oracle created a handful of certifications that were intended for database administrators and Forms developers. While the number of exams fluctuates, however, as original ones are added and worn ones retired, there are currently almost 300 offered. Less than a third of those exams are specifically about the Oracle RDBMS. The current counts and categories of the exams available are:
● Applications — 82● Database — 84● Enterprise Management — 3● Industries — 28● Java and Middleware — 66● Operating Systems — 15● Systems — 16● Virtualization — 3● Foundation — 2
In particular, Oracle’s acquisition of Sun expanded their certification program beyond the Oracle RDBMS. Thousands of IT professionals who own never worked with the Oracle database hold one or more Java certifications. The Solaris and MySQL certifications are likewise not directly related to the Oracle database. The company has purchased numerous other software evolution companies over the years, many of which had existing certification programs that own been rolled into Oracle’s offerings.
As a result, “Oracle” certifications are no longer restricted to database geeks. An information technology professional interested in working as a system administrator might find it rewarding to grasp the Oracle Linux Administration exams: Oracle Linux 5 and 6 System Administration (1Z0-100) and Oracle Linux 6 Advanced System Administration (1Z0-105). Given the current paradigm shift to virtualization, he might deem supplementing those credentials by pursuing a certification for Oracle VM 3.0 (1Z0-590). nothing of these certifications require any knowledge of the Oracle database.
In addition, many of the applications owned by Oracle are widely used by organizations around the globe. Taking PeopleSoft as a unique example, there are eight certifications dedicated to this application suite alone. The PeopleSoft 9.2 Human Resources Essentials exam is targeted at professionals who specialize in the sales and installation of this solution. That said, the exam is open to anyone and there are several reasons why a human resource professional might rule to merit the certification even though they will never breathe liable for installing it. Three potential examples include:
1) The company where the HR professional works (let’s summon him “John”) is about to migrate their human resources software from another package to PeopleSoft. John has been given the job of working with the application integrator to ensure that the migration goes smoothly. Studying for and earning this certification will allow John to combine his inside knowledge of the organization and their legacy application with an in-depth understanding of the capabilities provided by PeopleSoft. This would almost certainly result in a smoother transition to PeopleSoft.
2) The company where John is working is considering affecting to PeopleSoft from their current human resources application. Learning the capabilities of PeopleSoft will allow John to provide upper management with an insider’s perspective on whether the run makes sense. Software transitions of this kind are both expensive and disruptive. It makes sense for an organization to invest the time and resources to gain a better understanding of whether the migration is worthwhile.
3) John is either unemployed or looking to change positions. He routinely sees job listings that reference PeopleSoft experience, but he has never worked with that application. Earning the certification and adding it to his resume may breathe just the thing to promote his career.
With minor changes of wording, the above three scenarios could breathe applied to several dozen certification exams offered for various Oracle applications. Anyone whose job role involves using one or more of these applications may find it worthwhile to merit the associated certification. The knowledge has a qualified likelihood of making them more effectual at their job. Adding skills applicable to your job role will almost invariably help career prospects.
The incredible scope of exams available connote that a very broad set of people can locate a certification that matches their interests and skills. In an earlier article at CertMag.com, DBA or Developer? Deciding which one suits you best, I celebrated the weight in choosing a career path of matching your interests and aptitudes to the tasks you will breathe performing.
If you arbiter that earning a certification for one or more Oracle products might breathe a qualified career move, check out the everyone Exams page on the Oracle certification website. peep through everyone of the offerings to determine which (if any) look lively to you. If you find one or more that look enjoy reasonable candidates, then I would recommend performing some additional research into them.
Only you know what your interests are. For example, if you detest social media, then it should grasp you only seconds to sack Oracle social Relationship Management Cloud Service 2014 Essentials as a potential certification objective. If the reverse is true, you might want to spend some time researching what that test entails. Check out job sites to contemplate if companies in your region mention the tested skills. elope some searches in Google to contemplate what information you can find about the product. quiz questions on product forums from people who are using it. Career choices own a lasting impact, so it is principal to spend the time required to result qualified ones.
If you result not own any knowledge or abilities useful to companies, then you are likely to breathe restricted to jobs that require candidates with few or no skills (such as the fast-food industry or politics). At this jiffy in time, Oracle is a title to conjure with. It has the lion’s share of the relational database market and is very profitable. So long as they maintain their position as the top dog in that market and continue to own applications that are widely used around the world, having Oracle skills will breathe useful to IT professionals. As celebrated in the first two paragraphs of this article, these things change over time. For the moment, however, if you are shopping around for a certification program (and company) to hitch your star to, Oracle is arguably a qualified choice.
