I have passed my Oracle 9i Certified Master exam in 2004. Since then the 10g exam has been in preparation.
Well, according to dba10gocm_upgrade the OCM Upgrade exam content has not been finalized.
There is also an OCM Member restricted website. In case you have the password, you can read :
More Great Benefits Coming Soon . . .
Soon=Forever+a few centuries?
According to Paul answer to my comment on his blog : we are developing a one-day upgrade exam for 10g OCM to 11g OCM and will include a streamlined path for 9i OCM to 11g OCM
Ok, I am a bit pessimistic about the future of OCM. As OCM Gregory Guillou posted on my previous blog post :
It doesn’t really make any sense to have an upgrade exam for the what ? 50 9i OCM ?
Since about last year there is a way more succesful exam suite. The Oracle Certified Expert. I did myself pass the rac and sql ones.
Ok, the news :
There is a new Oracle Certified Expert exam which is called : Oracle Database 11g Performance Tuning Certified Expert
The exam is in Beta now, good luck to you!
