Re: 10g and 11g together

Could you describe your end objective a bit more, and perhaps describe your current and proposed environment (hardware/OS wise) for some more accurate comments?

As an overview of my thought process:

• Oracle Server s/w is installed in an ORACLE_HOME, which defines one version of s/w and it's patches
• Multiple ORACLE_HOMEs are allowed on a server, therefore multiple versions of Oracle s/w are permitted (and may be run concurrently)
• One instance is basically the s/w running from one ORACLE_HOME, interworking with one SGA
• One ORACLE_HOME "controls" one or more Oracle Database, each with it's own instance
  • exception: RAC, multiple instances from multiple ORACLE_HOMEs control one database.
• The version upgrade process generally encourages two ORACLE_HOMEs, with the new HOME taking over control of an existing database

Hope that helps
