|

<div><div class="section"> <p>This example uses a directory, MyDirectory. The directory contains
|
||
|
|
objects that you will save on a daily basis. Your current save strategy ends
|
||
|
|
jobs that make changes to the objects in the directory for the entire time
|
||
|
|
that the you are saving the directory.</p>
|
||
|
|
<p>The objects that exist in the
|
||
|
|
directory may or may not be journaled.</p>
|
||
|
|
<p>The several hour save-outage
|
||
|
|
time can be greatly reduced by the following steps: </p>
|
||
|
|
</div>
|
||
|
|
<ol><li class="stepexpand"><span>End all application jobs that are making updates to the objects
|
||

|
in MyDirectory.</span></li>

|
<li class="stepexpand"><span></span> Submit the following command as an individual batch
|
||
|
|
job: <pre>SAV DEV('/QSYS.LIB/TAP01.DEVD') +
|

OBJ('/MyDirectory') SAVACT(*SYNC) +

</pre>
|

<p>The objects in directory MyDirectory reach a checkpoint
|
||
|
|
together, as specified by SAVACT(*SYNC). The server saves the objects TAP01.
|

|
|
The server sends the message indicating that checkpoint processing is complete
|

|
|
to MSGQ1</p>
|
||
|
|
</li>
|
||
|
|
<li class="stepexpand"><span>After checkpoint processing is complete, the message queue receives
|
||
|
|
the message CPI3712. If checkpoint processing does not complete for the objects,
|
||
|
|
message queue receives the message CPI3722 and the save operation
|
||
|
|
ends.</span></li>
|

<li class="stepexpand"><span>After receiving CPI3712 message, start the application jobs that
