<h1 class="topictitle1">Commitment control during activation group end</h1>
|
||
|
|
<div><p>The system automatically ends an activation-group-level commitment
|
||
|
|
definition when an activation group ends. </p>
|
||
|
|
<p>If pending changes exist for an activation-group-level commitment definition
|
||
|
|
and the activation group is ending normally, the system performs an implicit
|
||
|
|
commit operation for the commitment definition before it is ended. Otherwise,
|
||
|
|
an implicit rollback operation is performed for the activation-group-level
|
||
|
|
commitment definition before being ended if the activation group is ending
|
||
|
|
abnormally, or if errors were encountered by the system when closing any files
|
||
|
|
opened under commitment control scoped to the activation group.</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> An implicit commit or rollback operation is never performed during activation-group
|
||
|
|
end processing for the *JOB or *DFTACTGRP commitment definitions. This is
|
||
|
|
because the *JOB and *DFTACTGRP commitment definitions are never ended due
|
||
|
|
to an activation group ending. Instead, these commitment definitions are either
|
||
|
|
explicitly ended with an ENDCMTCTL command or ended by the system when the
|
||
|
|
job ends.</div>
|
||
|
|
<p>The system automatically closes any files scoped to the activation group
|
||
|
|
when the activation group ends. This includes any database files scoped to
|
||
|
|
the activation group opened under commitment control. The close for any such
|
||
|
|
file occurs before any implicit commit operation that might be performed for
|
||
|
|
the activation-group-level commitment definition. Therefore, any records that
|
||
|
|
reside in an I/O buffer are first forced to the database before any implicit
|
||
|
|
commit operation is performed.</p>
|
||
|
|
<p>As part of the implicit commit or rollback operation that might
|
||
|
|
be performed, a call is made to the API commit and rollback exit program for
|
||
|
|
each API commitment resource associated with the activation-group-level commitment
|
||
|
|
definition. The exit program must complete its processing within 5 minutes.
|
||
|
|
After the API commit and rollback exit program is called, the system automatically
|
||
|
|
removes the API commitment resource.</p>
|
||
|
|
<p>If an implicit rollback operation is performed for a commitment definition
|
||
|
|
that is being ended due to an activation group being ended, then the notify
|
||
|
|
object, if one is defined for the commitment definition, might be updated.</p>
