Uninstalling MQ for iSeries

Uninstalling MQ

Perform a standard deletion of the WebSphere MQ for iSeries™ product if you want to retain your user data, for example, because you intend to reinstall the product at a later date.

To perform this deletion:

Quiesce WebSphere MQ for iSeries. (See Quiescing MQ.)
End the WebSphere MQ subsystem, by issuing the command:
```
ENDSBS SBS(QMQM)
```
Ensure that no locks are held on the library QMQM, by issuing the command:
```
WRKOBJLCK OBJ(QMQM) OBJTYPE(*LIB)
```
Use the Delete Licensed Program (DLTLICPGM) command to delete the base product (and also the samples if you chose to install them). To delete the base product and the samples, issue the command:
```
DLTLICPGM LICPGM(5724H72) OPTION(*ALL) OUTPUT(*PRINT)
```
To delete only the samples, issue the command:
```
DLTLICPGM LICPGM(5724H72) OPTION(1) OUTPUT(*PRINT)
```

Delete WebSphere MQ for iSeries in this way deletes only the objects that belong to WebSphere MQ: the QMQM library, and the subdirectories that belong to MQ server below the /QIBM/ProdData/mqm directory.

If that leaves no other subdirectories (for example if the MQ Java™ Client is installed it uses subdirectories there) then the /QIBM/ProdData/mqm directory itself is deleted.

None of the queue manager journal libraries, or IFS directories based upon /QIBM/UserData are removed.
