How To Upgrade ASM from 10.2 to 11.1 (single Instance configuration -Non-RAC)

The present document explains how to upgrade an ASM instance from 10.2 to 11.1 release (single Instance configuration / Non-RAC).

Solution

1) Install the new 11g ASM Oracle Home (on a different directory) as described in the Installation Guide associated with your specific platform :

http://www.oracle.com/pls/db111/portal.portal_db?selected=11&frame=

==)> Installation Guide for<your platform/Os>

2) Shutdown all the database instances that are using ASM as storage option.

3) Shutdown the ASM instance.

4) Reconfigure the CSS service:

Connect as root OS user and execute:

$ORACLE_HOME/bin/localconfig reset

Where: $ORACLE_HOME is the new 11g ASM Oracle Home

5) Startup the ASM instance (connected as Oracle OS user) as usual (using the 10g Oracle Home).

6) From another graphical session, set the environment variables (ORACLE_HOME, PATH, etc.) pointing to your new 11 ASM Oracle Home.

7) Then execute the DBUA from the new ASM 11gOracle_Home/bin/dbua:

DBUA will show 2 options:

=)> upgrade ASM instance.
=)> upgrade the database

8) Select [upgrade ASM instance] option. The DBUA will upgrade your ASM instance to release 11g automatically.

9) Finally, please startup the databases that are using ASM as storage option.

Note: The databases will not be affected with the ASM upgrade, the databases will remain in the original release.
