Hi Paul

If stopping the application is out of the question you are in kind of a tricky spot, though making things wait longer for a lock might help. My own experience on waits is that they only ever get longer and eventually exceed what's been allocated anyway.

Some questions:
- is the SWA across all the libraries, i.e. do you have everything in one gigantic checkpoint ?
- How long does it typically take to get a checkpoint ?
- What does "I know data areas are excluded from SWA." mean - do you exclude data areas from your save, or something else ?
- Would it be possible to save the library containingg the problem data area (if it's only one) individually to shorten the checkpoint time ? i.e.
do two SWA's

During our nightly BRMS full SWA, one of our applications experienced
CPF1063 - Cannot allocate data area JRNPGM01 in library BRCPGMS
followed by a RNQ0431 - Data area *LIBL/JRNPGM01 was allocated to
another process (C G D F).

BRMS was in the process of doing its check point processing for this
library, BRCPGMS. The check point processing only lasts for a few minutes.

The application needed to update the data area, but it was locked by
the save, the application went into MSGW.

I know data areas are excluded from SWA.

I can create a monitor that would automatically answer the RNQ0431
with a G, which would allow the application to continue without going into a MSGW.

Any recommendations from the group on handling locks caused by BRMS
causing applications to fail.
Stopping the application is not an option.
Excluding the object from the save is not an option.

Thank You
