I will show a upgrade of an existing Single Instance 18.104.22.168 database with ASM, having
same ORACLE_HOME, to Oracle 11gR2 with ASM.
The Oracle environment is a Dataguard structure bases on 11.1.06 with ASM.
The new situation will be one ASM instance with 11.2 and Oracle instance 22.214.171.124
The upgrade needs to be performed in two phases:
Done 1. Upgrade the ASM instance of one of the DG’s
Pending 2. Upgrade the other ASM instance of the DG structure
Pending 3. Upgrade Oracle databases.
There are three ways to upgrade already existing ASM instance:- Using OUI of Grid Infrastructure
- Using ASM Configuration Assistant
- Manual upgrade
The recommended method to upgrade ASM instance is to use OUI of Grid Infrastructure,which I will used. From Oracle 11gR2 onwards ASM is part of Grid Infrastructure and we need to download Grid Infrastructure software first. To download the software for 11gR2 Grid Infrastructure
