As another alternative, the cleanipc script can be used to free the IPC resources allocated to a particular AIX user, as follows:
cleanipc [ userId ]
If the userId parameter is not specified, cleanipc by default uses the environment variable USER.
The cleanipc script should be run only after all DSOM processes have ended. A limitation of cleanipc is that it is not able to distinguish between resources that were created by DSOM and resources created by other products. As a result, cleanipc may affect other applications.
