RE: SAVOBJ checkpoint failure

I was able to do a CPYLIB and everything copied correctly. I was then able to do the SAVOBJ on the new temp library. When we killed the job, I was then able to do a SAVOBJ on the original library.

Depending on how many source members there are, you might be able to copy them (use 3 from PDM) to another library. I’d create a new LIB, create new SRCPF then copy there. Now you won’t have to worry about the commit
control as you have a copy that’s useful. You might even detect which
source member is giving you the grief.

Then you can proceed without trepidation to end that job and potentially recreate the original.

Since it’s reasonably rare to have source files under commit control, I’m curious about what they are used for.

There are only 2 objects in the library - source files QDDSSRC and

commits for either of those files (actually no changes at all committed or open).
I don't understand why the checkpoint process has a problem with the
library if neither object has open commits. That issue causes me to
question if I add the *NOCMTBDY would I be able to restore and use the
two files without jumping through the ADD/RMVJRNCHG hoops. Will the
system think there are still "open commits" for the file(s) even
though there were none to begin with?

As for killing the job, it is currently stuck on a level check. I do
not know what it does (not an application that I support) and I don't
know what killing it would do to the data. I have already reached out
to the support team but I have not gotten anywhere yet. I have
informed them that the job will be killed by EOD if they have not resolved it by then.

The system would only look to see if there is a commit that is still
open. If so then yes, you would need the journal change to get after that
object. Can you not end the job, since it’s not doing anything? Then
restart it? That of course means you need to know what started it in
the first place. If this is an ODBC or other SQL connection dollars
to donuts the source job is gone/failed, so this one is just waiting
for instructions. You would have to end it anyway in that case.

Does anyone know the details about the *NOCMTBDY? The help text
worries me, specifically that first line of the second paragraph.

There should be nothing changed in this library by this job (still
trying to get access to the journal info to confirm) and if not, do I
still have to do APYJRNCHG or RMVJRNCHG to restore and use the source
files in it even though nothing in the library / files was changed?

*NOCMTBDY
The system will save objects without requiring transactions with
pending record changes to reach a commit boundary. Therefore,
objects may be saved with partial transactions.

If you restore an object that was saved with partial transactions,
you cannot use the object until you apply or remove journal changes
(APYJRNCHG or RMVJRNCHG command) to reach commit boundaries. You
will need all journal receivers that contain information about the
partial transactions to apply or remove the changes. Until you
apply or remove the changes, any future save of that object will
include the partial transactions, even if you do not specify
*NOCMTBDY.

I was able to chase this down.

There is a job running using commitment control and even though it
has
not changed anything in the problem library, apparently just having
the library in the libl is enough to cause the checkpoint to fail.

It looks like there is a parm SAVACTWAIT(xxx *NOCMTBDY). I don't
know
anything about it but I'll be checking that out.

Thanks all for your help.

Is there a way to find what file(s) / member(s) might have this problem?

Someone might have had commitment control active (STRCMTCTL) in
their
job, for testing, and then opened some of those source members in SEU ...?
I think that when it says it "failed to reach a checkpoint" that
means
there is some commitment control going on ...

We have a process that backs up our dev source and pushes it over to
our prod machine for offsite backup. This has been running for
about
6 months with no problem. We are doing a SAVOBJ to a *SAVF with
SAVACT(*LIB) and now it is failing on one library with the message



Save ended. Unable to reach checkpoint.



I just did the command manually and got the same error. I
immediately
did a WRKOBJLCK on the library and there are no locks on it. This
process works on other libraries so it is just one specific library
that is "broken".
Since the library only contains source, there shouldn't be anything
using it.



I recommended opening a ticket with IBM but the admins want to have
a
meeting first to discuss this and that is not going to happen until
tomorrow which means we lose another night's backup.



Does anyone have any idea what I can look at in advance?
