AIX 64 Bit - Oracle 11.2.0.3 Installation/Upgrade - 10.2/11.1
AIX 64 Bit
Oracle 11gR2 - 11.2.0.3
As part of the 11gR2 install, you are asked to select DBA and DBOPER owners. How is this determined/verified selected properly?
Also, migrating DB's: Ran the dbupgdiag.sql and utlu112i_3.sql
Should we enable 11.2 listener first?
or
Should we migrate all DB's, then do listener or can we try one DB with new listener then move the rest and then change to the 11.2.0.3 LSNR?
Is there a best practice here?
