<h1 class="topictitle1">Work with commitment definitions in a distributed relational database</h1>
|
||
|
|
<div><p>Use the <span class="cmdname">Work with Commitment Definitions (WRKCMTDFN)</span> command
|
||
|
|
if you want to work with the commitment definitions on the server.</p>
|
||
|
|
<div class="section"> <p>A <em>commitment definition</em> is used to store information about
|
||
|
|
commitment control when commitment control is started by the <span class="cmdname">Start
|
||
|
|
Commitment Control (STRCMTCTL)</span> command. These commitment definitions
|
||
|
|
might or might not be associated with an active job. Those not associated
|
||
|
|
with an active job have been ended, but one or more of its logical units of
|
||
|
|
work have not yet been completed.</p>
|
||
|
|
<p>The <span class="cmdname">Work with Commitment
|
||
|
|
Definitions (WRKCMTDFN)</span> command can be used to work with commitment
|
||
|
|
definitions based on the job name, status, or logical unit of work identifier
|
||
|
|
of the commitment definition.</p>
|
||
|
|
<p>On the STATUS parameter, you can specify
|
||
|
|
all jobs or only those that have a status value of *RESYNC or *UNDECIDED.
|
||
|
|
*RESYNC shows only the jobs that are involved with resynchronizing their resources
|
||
|
|
in an effort to reestablish a synchronization point; a <em>synchronization
|
||
|
|
point</em> is the point where all resources are in consistent state.</p>
|
||
|
|
<p>*UNDECIDED
|
||
|
|
shows only those jobs for which the decision to commit or roll back resources
|
||
|
|
is unknown.</p>
|
||
|
|
<p>On the LUWID parameter, you can display commitment definitions
|
||
|
|
that are working with a commitment definition on another server. Jobs containing
|
||
|
|
these commitment definitions are communicating using an APPC-protected
|
||
|
|
conversation. An LUWID can be found by displaying the commitment definition
|
||
|
|
on one server and then using it as input to the <span class="cmdname">Work with Commitment
|
||
|
|
Definitions (WRKCMTDFN)</span> command to find the corresponding commitment
|
||
|
|
definition.</p>
|
||
|
|
<p>You can use the <span class="cmdname">Work with Commitment
|
||
|
|
Definitions (WRKCMTDFN)</span> command to free local resources in jobs
|
||
|
|
that are undecided, but only if the commitment definitions are in a Prepared
|
||
|
|
(PRP) or Last Agent Pending (LAP) state. You can force the commitment definition
|
||
|
|
to either commit or roll back, and thus free up held resources; control does
|
||
|
|
not return to the program that issued the original commitment until the initiator
|
||
|
|
learns of the action taken on the commitment definition.</p>
|
||
|
|
<p>You can also
|
||
|
|
use the <span class="cmdname">Work with Commitment Definitions (WRKCMTDFN)</span> command
|
||
|
|
to end synchronization in cases where it is determined that resynchronization
|
||
|
|
will not ever complete with another server.</p>
