Moreover, we have a very active placement cell that provides 100% placement assistance to our students. The cell also contributes by training students in mock interviews and discussions even after the course completion.
The Oracle Certified Master (OCM) is the only certification that requires a hand-on exam. That in itself makes it very interesting as it is the only exam that provides proof you have ever sat in front of a working Oracle system. For this reason I think the OCM is a very worthwhile certification.
There are two issues I have with the OCM exam:
It is very expensive to complete this certification. The exam itself is very expensive and it requires the completion of two Oracle courses, which add to the price significantly. I just can't justify the price of that piece of paper. If your company is willing to pay for you to take the exam, great. If not, then I'm not sure it is worth the money.
You should also remember that you don't have access to the internet during this exam. You will only have the manuals, which you will have to navigate using the master index, not the search facility. I am great at remembering the approach needed to perform a task or fix an issue, but I am terrible at remembering syntax, which is one of the reasons I find my own website useful. I think it is pretty safe to say I would fail the OCM exam without a serious amount of syntax revision, as I would not have time to look through the manuals for syntax examples. I am not prepared to dedicate the amount of time necessary to have all of the possible variations of the syntax committed to memory. In my humble opinion, being a great DBA is not the same as being a syntax regurgitating machine.
- Prerequisite would be just :SQL + PL/SQL + Reports + Forms (which is nothing but Oracle Developer track). ...
- Apart from this you need to be a technical graduate like a BCA or BE or MCA or BSC-CS etc.
- You also need to a good communication skills.
Absolutely. Moreover, you can learn pretty much any other programming language as well without any prior programming knowledge. This can just be the first programming language you learn.
Actually, I have heard from my fellow programmer a story about a sales manager who often asked him to develop new reports. He wrote new SQL statements to extract the data needed over and over again until they negotiated that the guy who was developing that piece of software added a dialog to the program which allowed to enter arbitrary SQL DML statements and format the results in the way needed before printing them. He said the manager got the point pretty quickly and enjoyed preparing the reports himself and never asked the programmer to do that again )So, of course it is possible.
Our course ware is designed to give a hands-on approach to the students in Oracle 12 Certification. The course is made up of theoretical classes that teach the basics of each module followed by high-intensity practical sessions reflecting the current challenges and needs of the industry that will demand the students’ time and commitment.
It's definitely worth The worth of having the certification itself is arguable. Some companies might require developers to have at least an OCA certificate whereas some might not care and would regard experience as a good enough indicator.
Originally Answered: In how much time can we learn Oracle from scratch? Hi, it depends what you are targeting to learn. If it's SQL and PL/Sql, then it will take 3 hours of study for 2–3 months and you will be good to go.
If you are not considering Oracle Certification, you should. You found this blog because you have an interest in Oracle Certification. You may have heard that Oracle Certification can help you get a better job, better pay, more recognition, increased credibility. Those are all very good reasons to pursue certification, but the most important reason to get certified has nothing to do with external factors.
The time and effort you spend preparing for your certification exams gives you the most important benefit of earning an Oracle Certification - knowledge.
The knowledge and skills you learn during the process of preparing for your exam(s) give you confidence and personal satisfaction. You broaden your knowledge. You expand your skills beyond your daily responsibilities. You give yourself the power to troubleshoot, think creatively and push your skills to their limits.
Beneficial Features of Oracle 12 Certification
If your operating system is out of support or your hardware is end-of-life, you can perform a hardware migration with an export from the old database version and an import to the new one without running an in-place upgrade. A migration combines multiple benefits into a single project to minimise disruption and cost, and is generally Oracle 12 certication is used.
Often it’s challenging to understand the implications of different options for upgrades and migrations, or to work out how to combine projects to achieve desired goals efficiently. Producing a roadmap for your SAP landscape can help you to plan in the projects you need and understand the budget and timelines well in advance.
Speed up your SAP system with Oracle In Memory Support
Since the 30th June 2015, SAP have supported Oracle’s In-Memory features that are available in Oracle 12c.
- In-Memory computing keeps the database in high-speed RAM rather than relying on slower disk storage. It offers a performance improvement that is orders of magnitude faster than accessing data on disk. The safety of your data is maintained as any changes are committed to a disk before the transaction completes, just as it is for the memory buffer used for disk-based databases today.
- The whitepaper Using SAP NetWeaver with Oracle Database In-Memory contains a lot more detail, and describes how to use the Oracle Database In-Memory Advisor tool to advise you on how best to implement In-Memory for your actual Oracle usage statistics.
- As well as the In-Memory Advisor tool, you can also use a targeted approach by identifying long-running reports traditionally within your SAP system, using a traditional SQL trace such as transaction ST05 to identify the table access, and use In-Memory technology on those tables specifically.
- As memory continues to get larger and cheaper, In-Memory computing is becoming a game-changing technology to allow everything from faster batch jobs, faster reporting insight to give an enterprise better insight and beat competitors, and even better medical careand motor racing performance breakthroughs. If you are running SAP on Oracle 12c, you can start to see the benefits of In-Memory for your own organisation.
The licensed compression option: ACO: Advanced Compression
The advanced compression features of Oracle 12c are available to customers who have a license for the Advanced Compression Option (ACO). ACO compresses far more than IOTs with the following features:
- Advanced Row Compression (Oracle 12c) and OLTP Table Compression (Oracle 11g)
Compresses duplicate data within each database block. This means almost all tables are compressed, not just IOTs as above.
- Advanced Index Compression (Oracle 12c only)
Compresses indexes at the block level to significantly reduce the size of database indexes.
Compresses large object data types (LOB) that cannot be compressed with Advanced Row Compression
- Advanced Network Compression (Oracle 12c only)
With Oracle Client 12.1.0.2 or higher, you can compress the network data between Oracle and the SAP Application Server to use less bandwidth and improve response time.
- Recovery Manager (RMAN) Compression
Data is compressed before it is written to disk or tape, and doesn’t need to be uncompressed before recovery, leading to a reduction in storage costs of up to five times for backups. This is preferable to traditional compressed backups such as in brtools as no external tool is required and there is no additional (de)compression step.
- Data Guard Network Compression
Redo log data is compressed before it is sent over the network to standby databases, which can double redo transport speed.
SAP have found their customers using ACO can reduce data file size by a factor of three, improve buffer hit rate by 10%, and reduce physical reads from the database by 60% with compression without any impact of CPU utilization for regular transaction workload. There can be a 30% increase in amount of redo data generated however.
Oracle 12c is optimised for the Cloud
- The c in Oracle 12c, as with everything just now, stands for cloud. Oracle 12c is advertised by Oracle and has cloud-enabling features to back up these claims.
- Multitenant databases can float around and are “plugged in” to an Oracle 12c multitenant instance. Once the database is plugged in to an instance, it works to the application seamlessly without any changes required. Without multitenant, databases and the instance they run on are inherently linked, with a migration required to move the database around.
- Oracle see multitenant databases as the first step to the cloud, as they allow you to move databases between on-premise and the cloud, between cloud providers, or between different parts of a high-availability cloud design.
- One benefit could be to move your database to another Oracle instance before applying bundle patches to minimise downtime, or to move your database between different database-as-a-service solutions.
Other Cloudy Benefits of Oracle 12c
- Oracle’s whitepaper Plug into the Clouddescribes their view on cloud computing with Oracle 12c.
- Amongst their ideas, the use of a few multitenant database instances to manage a large number of databases is conducive to the efficient system administration that is required to get the best from a large complex cloud infrastructure. With less database instances to maintain and more flexibility, less administrators can manage a large landscape.
- The multitenant model also allows better security separation and data isolation than merely using separate schemas, as there are completely separate security access privileges for each database that has been consolidated into a multi-tenant environment. This facilitates database-as-a-service and enables the secure use of the cloud database resources.
