Remove a server instance without uninstalling the TSM server 6.x

1) Open a DOS command prompt and run “db2ilist”. This will list the TSM instances that are defined to DB2.

2) From the DOS command prompt issue “db2idrop <instance name>”. So if the instance you want to remove is “SERVER1? you would issue “db2idrop server1?

3) Open the registry to HKEY_LOCAL_MACHINE\SOFTWARE\IBM\ADSM\CurrentVersion\Server. Here you will find the instance. Remove the instance directory. Do not remove HKEY_LOCAL_MACHINE\SOFTWARE\IBM\ADSM\CurrentVersion\Server itself.

NOTE: Before making any registry changes it is always advised to export the registry incase you need to recover.

4) While in the registry the TSM instance service needs to be removed as well. It is located in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

NOTE: Before making any registry changes it is always advised to export the registry incase you need to recover.

5) Delete all files located in the instance directory. By default, they are located in C:\Program Files\Tivoli\TSM\<instance name>

6) Delete all log and DB volumes for the instance. The location of these volumes was determined at the time of configuration. There is no default location.

NOTE: Ensure that you are deleting the correct volumes for the instance. If you delete volumes for a different instance than you are removing, that instance will no longer be operational.

7) Also ensure that c:\<instance name> is deleted.

You are now ready to run the config again.
