$ cd $ORACLE_HOME/lib

4. Take a backup of existing original ODM library.

$ mv $ORACLE_HOME/lib/libodm11.so $ORACLE_HOME/lib/libodm11.so.org

5. create a soft link to veritas ODM library:

$ ln -s /opt/VRTSodm/lib/libodm.so $ORACLE_HOME/lib/libodm11.so

6. Start the database and check. Once the database instance is enabled with ODM, the following message is displayed in the Oracle alert log:

Oracle instance running with ODM: VERITAS 4.1 ODM Library, Version 1.1

Disable ODM

2. Shut down the database.

3. Change directories:

$ rm libodm11.so

5. Copy the orginal $ORACLE_HOME/lib/libodm11.sl or libodm11.so file back to disable the ODM library.
