<h1 class="topictitle1">Commitment control</h1>
|

|
|
<div><p>Commitment control is a function that ensures data integrity. It
|
||
|
|
allows you to define and process a group of changes to resources, such as
|
||
|
|
database files or tables, as a transaction. </p>
|
||
|
|
<p>Commitment control ensures that either the entire group of individual changes
|
||
|
|
occur on all systems that participate or that none of the changes occur. IBM<sup>®</sup> DB2
|
||
|
|
Universal Database™ for iSeries™ uses the commitment control function to commit
|
||
|
|
and rollback database transactions that are running with an isolation level
|
||
|
|
other than *NONE (No Commit).</p>
|
||
|
|
<p>You can use commitment control to design an application so that the system
|
||
|
|
can restart the application if a job, an activation group within a job, or
|
||
|
|
the system ends abnormally. With commitment control, you can have assurance
|
||
|
|
that when the application starts again, no partial updates are in the database
|
||
|
|
due to incomplete transactions from a prior failure.</p>
