Hi Guys,
I have a new project where I have to migrate about 150+ database environments from various solaris systems running Solaris 8 / 10 and residing on very different sun boxes (from 25k down to ancient/unsupported hardware) to AIX (power6).
As special bonus for me, about half of these DBs are supposed to become migrated to Oracle once stable as Sybase DBs on AIX.
I know that I can use the RPE2 values to estimate the cpu requirements - but since the memory needs on Solaris seem pretty different from AIX, is there any safe way to estimate at least roughly the memory needs on AIX? For Sybase I can probably choose the value that's assigned to ASE and add 2-4 GB memory for the system and should be safe - but what do I do with oracle since here the memory usage seems to be highly depending on the DB connections and what they're doing?
Has anybody done similar tasks in the past and would be happy to share experiences.
Thank you and regards
