<h1 class="topictitle1">Object locking: During save-while-active checkpoint processing</h1>
|
||
|
|
<div><p>During checkpoint processing, these locking rules can conflict with object-level
|
||
|
|
lock types of exclusive allow read (*EXCLRD); exclusive, no read (*EXCL);
|
||
|
|
and share update (*SHRUPD). Some object-level system commands and user applications
|
||
|
|
can acquire these lock types. User applications that acquire these object-level
|
||
|
|
locks generally conflict with save-while-active operations until the checkpoint
|
||
|
|
processing is complete for the objects. User applications that use system
|
||
|
|
commands that require these object-level locks also conflict with save-while-active
|
||
|
|
operations until the checkpoint processing is complete for the objects. Lock
|
||
|
|
conflicts can prevent the save operation from saving the object. Lock conflicts
|
||
|
|
can also can prevent applications from using the object. To eliminate lock
|
||
|
|
conflicts during checkpoint processing, you should end your applications until
|
||
|
|
checkpoint processing is complete.</p>
|
||
|
|
<p>In general, checkpoint processing operations prevent the following list
|
||
|
|
of operations from occurring for objects you are saving.</p>
|
||
|
|
<ul><li>Changing an object</li>
|
||
|
|
<li>Deleting an object</li>
|
||
|
|
<li>Renaming an object</li>
|
||
|
|
<li>Moving an object to a different library or folder</li>
|
||
|
|
<li>Changing the ownership of an object</li>
|
||
|
|
<li>Compressing or decompressing an object</li>
|
||
|
|
</ul>
