Re: Cleanup after program failure

[MWalter@xxxxxxxxxxxxxxx]

Matthias,

If the Program b is RPG, code error handling in  program B (i.e. *PSSR),
monitor for abnormal end of Program B in you setup CL and restore you
environment settings.
 I do this in my nighttime processes. If a program fails for some reason,
the driving CL sends a message to the QSYSOPR message queue and continues
on its merry way.

Good Luck

Mark

Hi guys,

I've been asked to code a call to program B from within program A.

The difficulty is that program B needs a different environment to
program A: A slight change in the library list and a modified data
area.

This is easily doable, make program A call a small CL which sets up
everything, then calls program B and when it returns undoes the
changes and finally returns to program A.

My problem is this: If program B (or the CL) fails for whatever
reason, program A regains control without the environment having been
restored to what it should be which could mean disaster.

How can I guard against this situation?

Thanks for your help.
Best regards,
Matthias
