Save IBM MQ data on IBM i

Save IBM® MQ data after removing unwanted FDC, trace, and JOB files.

Before you begin

You need to have completed the tasks to remove unwanted and indoubt messages and quiesced IBM MQ.

Create a save file for every queue manager library on your system. To do so, issue the command:
```
CRTSAVF FILE(QGPL/ queue-manager-library )
```
where the queue-manager-library name consists of the name of the queue manager preceded by QM.

Save your queue manager libraries into the save files. To do so, issue the commands:


SAVLIB LIB( queue-manager-library ) DEV(*SAVF)
SAVF(QGPL/ queue-manager-library )

Remove all unwanted FDC data from directory:
```
QIBM/UserData/mqm/errors
```
Remove old FDC files with the command:
```
RMVLNK OBJLNK('/QIBM/UserData/mqm/errors/*.FDC')
```
This command cleans up all files with an extension of 'FDC' in the IFS.
Remove old JOB files with the command:
```
RMVLNK OBJLNK('/QIBM/UserData/mqm/errors/*.JOB')
```
This command cleans up all files with an extension of 'JOB' in the IFS.
Remove all unwanted trace data from directory, or remove the whole directory:
```
QIBM/UserData/mqm/trace
```

Remove all trace files with the command:


RMVLNK OBJLNK('/qibm/userdata/mqm/trace/*')

Create a save file for IBM MQ IFS data. To do so, issue the command:
```
CRTSAVF FILE(QGPL/QMUSERDATA)
```

Save your IBM MQ IFS data, using the command:


SAV DEV('/QSYS.LIB/QGPL.LIB/QMUSERDATA.FILE') OBJ('/QIBM/UserData/mqm')

If you are going to run IBM MQ on a new machine, transfer the save files to the new machine.
