Re: Commitment control

["R. Bruce Hoffman, Jr." <rbruceh@xxxxxxxxxxxxx>]

Complicated question.

It can.

If the commit lock level is *ALL or *CHG, then the record lock can be held
by the first activation group until a commit occurs. During that time, the
other activation group is unlikely to be able to read the record.

It all depends on what you are defining as your transaction boundaries. If
you update in the first activation group, commit in the first activation
group and then turn control over to the second activation group and that
group updates and then commits before returning, you should be able to
accomplish your task, but of course, then the updates belong to different
transactions.

On the STRCMTCTL, you can specify that the commitment level is at the JOB or
the ACTIVATION GROUP level.
