1.Log in as a user with root authority.

2.Remove the instance by entering the following command:

DB2DIR/instance/db2idrop InstName

where DB2DIR is the location you specified during the DB2 Version 9 installation. The default installation path for Linux is /opt/ibm/db2/V9.1.

The db2idrop command removes the instance entry from the list of instances and removes the INSTHOME/sqllib directory, where INSTHOME is the home directory of the instance and where InstName is the login name of the instance. If you are storing any files in /sqllib directory, these files will be removed by this action. If you still need these files, you must make a copy of them before dropping the instance.

3.Optional: As a user with root authority, remove the instance owner’s user ID and group (if used only for that instance). Do not remove these if you are planning to re-create the instance.

Remove the database files from the systems or drop the databases before dropping the instance if you no longer need the databases. After dropping the instance the database files remain intact.

This step is optional since the instance owner and the instance owner group may be used for other purposes.
