<h1 class="topictitle1">End a long-running rollback</h1>
|
||
|
|
<div><p>You can find how to end long-running rollbacks that consume critical
|
||
|
|
processor time, lock resources, or take up storage space in this topic.</p>
|
||
|
|
<p>A rollback operation removes all changes made within a transaction since
|
||
|
|
the previous commit operation or rollback operation. During a rollback operation,
|
||
|
|
the system also releases locks related to the transaction. If the system contains
|
||
|
|
thousands of transactions, the system can take hours to complete a rollback
|
||
|
|
operation. These long-running rollbacks can consume critical processor time,
|
||
|
|
lock resources or take up storage space.</p>
|
||
|
|
<p>Before you end a long-running rollback, you need to know which commitment
|
||
|
|
definitions are being rolled back and what state the commitment definitions
|
||
|
|
are in. The State field for commitment definitions that are rolling back is
|
||
|
|
set to ROLLBACK IN PROGRESS.</p>
|
||
|
|
<p>Use the Work with Commitment Definitions (WRKCMTDFN) command to check the
|
||
|
|
status of a rollback by following these steps:</p>
|
||
|
|
<ol><li>Type WRKCMTDFN JOB(*ALL) from the character-based interface.</li>
|
||
|
|
<li>Type F11 to display the State field.</li>
|
||
|
|
</ol>
|
||
|
|
<p>If you end a long-running rollback, files that were changed during the
|
||
|
|
transaction will be left with partial transactions. You must not end a rollback
|
||
|
|
if your files cannot have partial transactions. To see which files were changed
|
||
|
|
during the transaction, choose option 5 to display status from the WRKCMTDFN
|
||
|
|
list. Press F6 to display resource status and select Record Level.</p>
|
||
|
|
<p>You must have All Object (*ALLOBJ) special authority to end a long-running
|
||
|
|
rollback. To end a long-running rollback, follow these steps:</p>
|
||
|
|
<ol><li>Type WRKCMTDFN JOB(*ALL) from the character-based interface.</li>
|
||
|
|
<li>Type option 20 (End rollback) on the commitment definition you want to
|
||
|
|
end.</li>
|
||
|
|
</ol>
|
||
|
|
<p>Files with partial transactions have the Partial Transactions Exist, Rollback
|
||
|
|
Ended field set to *YES in the output from the Display File Description (DSPFD)
|
||
|
|
command. You must remove partial transactions before the file can be used.
|
||
|
|
You can remove partial transactions by deleting the file and restoring the
|
||
|
|
file from a prior save. If you do not have a prior save, you can use the Change
|
||
|
|
Journaled Object (CHGJRNOBJ) command to reset the Partial Transaction Exists
|
||
|
|
state so that you can open the file. Using the CHGJRNOBJ requires you to edit
|
||
|
|
the file to bring the file to a consistent state. You must use the CHGJRNOBJ
|
||
|
|
command only if no prior save is available.</p>
