I do DBA work for Oracle (inc Exadata) and Postgres - as well as also a lot of other things.
A lot of what you need to know is quite theory based as most performance tuning is quite manual. Oracle training isn't cheap and it's not an easy skill base to break into. Would your work fund a training course?
Have you don't any DBA work before on other RDBMS? Is this your first foray into DB admin?
What versions are you running in house? Are you running any RAC?
So you have two 11g courses:
Oracle Database 11g: Administration Workshop I Release 2
Oracle Database 11g: Administration Workshop II Release 2
Both are needed although you may wish to still do the 12c equivalents instead.
I would then suggest doing the Oracle Database 11g: RAC Administration Release 2 course as well.
Have you done the first workshop?
Burnsy you may be able to answer me a question if you don't mind
Currently have a windows server running a local oracle db. I want to replace the server with a newer model with a drive attached to a san containing the db. The san has a replication partner to a sister site. I want to know if it's possible to build an identical server at the sister site, and use windows disk clustering set to manual failover. Then, if the primary site or server fails, I can simply fail over to the remote server
Thanks
I would suggest not trying to run Oracle in Windows, just incase that was your plan.
