Ricky,
The XA file backup has a number of steps:
1. Run the user-defined "Pre-Backup" command (if one exists).
2. Get "Dedicated Mode"
3. Execute the "pre-backup processing". This "pre"-processing does not do any actual file clean-up, it just verifies that the XA environment is in a state where it can be backed-up (e.g. all required batches are Closed/Finished, no other XA jobs have terminated abnormally, etc. )
4. Backup the libraries (AMFLIB, AMTLIB...)
5. Execute the "post-backup processing". This is where all the file clean-up takes place.
6. Run the user-defined "Post-Backup" command (if one exists).
7. Release "Dedicated Mode"
The XABCKPRC command can be used to run all these steps EXCEPT for step 4, the actual backup of the XA libraries. (It does not do the actual backup)
When you run the command you specify whether you want to run the "PRE" backup processing (steps 1, 2, 3, & 7), the "POST" backup processing (steps 1, 2, 5, 6, & 7), or "BOTH" (steps 1, 2. 3, 5, 6, & 7).
In a scenario where you are using BRMS (or other backup utility) to do the actual XA library (AMFLIB, AMTLIB) backup you could first run the XABCKPRC command (with the "PRE" option) to verify the XA environment(s) is ready to be backed up, then use BRMS to do the actual backup of the libraries, then run the all XABCKPRC command a second time (with the "POST" option) to do the post-backup environment(s) clean-up.
(If you have multiple XA environments on your system you can specify on the XABCKPRC command to run the selected processes ("PRE", "POST", or "BOTH") on multiple environments. (It will run the selected processes for the XA environments one-at-a-time if run in QINTER or from a single-thread job queue, or it will run the processes for the XA environments "in parallel" if you specify on the command the to run the processing from a job queue that allows multiple concurrent processing of submitted jobs. [e.g. QSYSNOMAX]).
In your situation Ricky - where you are doing the actual backup of the libraries on an HA machine - I'm thinking the following might work for you:
1. Run the XABCKPRC command on the production system with the "PRE" option. This will run any user-defined pre-backup command (say to close transaction batches) and will verify the XA environment(s) can be backed-up.
2. Assuming the environment(s) can be backed-up then:
a. stop the "mirroring" to the HA system
b. initiate the backup on the HA system (from the production machine)
c. run the XABCKPRC command a second time on the production machine with the "POST" option to clean-up the XA environment(s)
d. continue production work on the production system
3. When the backup on the HA machine is completed re-start the mirroring process to the HA machine and allow it to 'catch-up'

Thanks for the command. That'll be helpful. I still have a question though.
The backup is being performed on our HA system. The backup process is initiated from the production machine. We want to run the Mapics processes to do any cleanup on our production machine. For example, clean up batches, end all unattached jobs, clean up jobact file, etc... Once those are complete we would submit a remote command to the HA box to perform the actual backup of the system.
I guess the real question is: what processes need to be run before and after the backup is submitted to run on our HA box? The command won't work for us on the production machine if it's going to attempt to perform the save.
