SQL DBAs Work on Windows platform, however they may possess knowledge of UNIX or Linux OS. Complexity increases with Oracle since you are required to know much more things to get the job done.

In oracle there where been different types of courses are been involved and there is no fixed option for the best Oracle certification, however, the Oracle Database 12c is an excellent option.

But there are so many packages and so many special functionalities that you might still need some more time to focus on them. But I guess that will happen with time. However, if you are thinking of learning Oracle applications, then it is a different ball game.

Most of the companies are using Oracle database on various platforms. Means chances of Oracle DBA jobs are more at any type of industry like telecom, finance, banking, etc. This is might be one of the valid reason for choosing Oracle DBA career.
The best features to expect in Oracle Database
As DBA's are always excited about the upcoming features, we will share below some of the main things.
Stability
- First of all, it was very clear that Oracle's main focus for the 19c database will be stability. This will be the final release for the "12cR2" family. So it was repeated multiple times: "don't expect to see many new features in this release", what in our opinion is really great.
- Since 12.1.0.1, Oracle has been implementing a lot of core changes in Oracle Database (like multi-tenancy, unified audit, etc) and it's still very hard nowadays to find a stable 12 release to recommend. 12.1.0., however many bugs are unfixed and it lacks a secure PDB layout (PDB escape techniques are pretty easy to explore). 18c will probably be ignored by all as it was a "transition" release, so we hope that 19c becomes the real stable one, as 11.2.0.4 was for 11g release family.
Now comes the real features...
Automatic Indexing
- This is indeed the most important and one of the coolest features I've even seen in Oracle DB. Once this kind of automation is implemented and released, it will open doors to many other product automations (like automatic table reorganization, automatic table encryption or anything you can imagine).
- The automatic indexing methodology will be based on a common approach to manual SQL Tuning. Oracle will capture the SQL statements, identify the candidate indexes and evaluates the ones that will benefit those statements. The whole process is not something simple.
- Basically, Oracle will first create those indexes as unusable and invisible (metadata only). Then, outside the application workflow, oracle will ask the optimizer to test if those candidate indexes improve the SQL performance. In case the performance is better for all statements when indexed is used, it will become visible. If performance is worse, it remains invisible. And if it only performs better for some statements, the index is only marked visible for those SQLs (via SQL Patch, maybe).
- The automation will also drop the indexes that become obsoleted by the newly created indexes (logical merge) and also remove the indexes that were created automatically but have not been used in a long time. Everything is customizable. For more details, we need to wait for the Beta Release!
Real-time Stats + Stats Only Queries
With those features, you will be able to turn on the real-time stats for some of your database objects and it will be possible to run some SQLs that will query only the object stats, not doing a single logical read! Cool, isn't it?
Data-guard DML Redirect
- When you have a physical standby, opened in read-only mode, and plug in it some type of report tool that needs to create an underlying table or insert some log lines to operate, you have a problem.
- With this feature, you can define some tables (or maybe schema, it's not clear yet) and you will be able to run DMLs on them.
- So Oracle will redirect that DML to your primary and reflect the changes on your standby, not impacting those tools.
- This can be dangerous if not configured properly but will also allow us to do many new things.
Partial JSON Update support
When you update a JSON data column, currently Oracle needs to upload the whole new column value to the database and validates. With this, we will now be able to update just a part (like a tag) of a json data.
