Are the higher values required for sga_target temporary or permanent when upgrading from 10g to 11gR

  We recently upgraded to Oracle Enterprise Edition Database 11gR1 (11.1.0.7) from 10g (10.2.0.4) on a Sun Sparc running Solaris 10, patch 8.  We used Automatic Shared Memory Management (ASSM) in Oracle 10g.  For each database, the pre-install script indicated that we needed to increase sga_target.  For example, the sga_target needed to be updated to at least 672MB (up from 370MB) for one of the databases. 

 

I’m wondering if this is a temporary increase due specifically to the upgrade process in which case I can knock the parameter back down, or if this is a new permanent value and 11gR1 requires the higher SGA_target value.

Howdy, Stranger!
