This is a design limitation as it stands in V5R1.

Hi Al,

What I was trying to say was that if three files are journalled to the same
journal, then if one save operation, with save-while-active, tries to save
just two of the files, the save will not complete if there are pending
record
changes for the third file. Even though the third file is not being saved!

I just did the following experiment:

1. Create three files - FILEA, FILEB and FILEC
2. Journal all to JRNL001
3. savobj obj(FILEA FILEB) savact(*SYNCLIB)

If an RPG program is updating only FILEC, as long as there are pending
changes for FILEC, the savobj command will fail. The message issued will be
CPF377F "Save-while-active request prevented by pending record changes. "

If a large number of files are journalled to the same journal, and you are
trying to save a subset of them, SWA will wait for no-pending changes on
ALL
files within the journal.

This caught us out last year !

I hope this expalins what I was trying to say more clearly :)

With all due respect, the pending commit does have to do with the file that
is being journaled.  This is a SWA limitation, and it involves a specific
application design, and providing sufficient time in the SAVACTWAIT
parameter to let the commit cycle to complete.

I don't know if this helps but we discovered that the file with pending
changes need not be one of the files being saved.

It seems that the OS/400 save object commands, when using
save-while-active,
can be held up by any file that is locked by a commitment control cycle,
when
that file is using the same journal as the objects being saved.  The
pending
commitment control cycle does not have to directly involve one of the
objects
being saved.
