<div><div class="section"><p>If a library contains an object, you can use the Display Object
|
||
|
|
Description (DSPOBJD) command to find out when the server saved the object.
|
||
|
|
If the QSYS library contains an object, you can use the DSPOBJD command to
|
||
|
|
display the appropriate data area that is shown in Data areas that contain
|
||
|
|
save history.</p>
|
||
|
|
<div class="p">You can also use the DSPOBJD command to obtain the save
|
||
|
|
history for document library objects (DLO) in libraries. Use the Display Document
|
||
|
|
Library Object Name (DSPDLONAM) command to find the system object name and
|
||
|
|
the ASP ID of the DLO. On the DSPOBJD command, specify the system object name
|
||
|
|
on the OBJ parameter. In the library name field, specify <samp class="codeph">QDOCxxxx</samp> where <samp class="codeph">xxxx</samp> is
|
||
|
|
the ASP ID. For example, for auxiliary storage pool (ASP) 2 the library name
|
||
|
|
would be <samp class="codeph">QDOC0002</samp>. <div class="note"><span class="notetitle">Note:</span> For ASP 1, the system ASP, the library
|
||
|
|
name is QDOC, not <samp class="codeph">QDOC0001</samp>.</div>
|
||
|
|
</div>
|
||
|
|
<div class="p">For objects that
|
||
|
|
you store in directories, you can use the output from the SAV command to maintain
|
||
|
|
save history information. To use the output, you must elect to keep the save
|
||
|
|
history information when you issue the SAV command. To keep the save history
|
||
|
|
information, specify either *PRINT or a stream file or user space path name
|
||
|
|
on the OUTPUT parameter of the SAV command. <div class="note"><span class="notetitle">Note:</span> The output from the SAV
|
||
|
|
command does not store the last saved data for objects in directories. See
|
||
|
|
Save changed objects in directories for instructions to save only changed
|
||
|
|
objects.</div>
|
||
|
|
</div>
|
||
|
|
<p>The following commands do not update the save history
|
||
|
|
information for the individual objects that the server saves: </p>
|
||
|
|
<ul><li>Save System (SAVSYS)</li>
|
||
|
|
<li>Save Security (SAVSECDTA)</li>
|
||
|
|
<li>Save Configuration (SAVCFG)</li>
|
||
|
|
<li>Save Save File Data (SAVSAVFDTA)</li>
|
||
|
|
<li>Save System Information (SAVSYSINF)</li>
|
||
|
|
</ul>
|
||
|
|
<p>For some save operations, the server updates history information in
|
||
|
|
a data area. In some cases, the server updates the data area instead of updating
|
||
|
|
the individual objects. In other cases, the server updates the data area in
|
||
|
|
addition to the individual objects. </p>
|
||
|
|
<p>Beginning with V5R1, when you install
|
||
|
|
the operating system, the server will update the data areas. However, the
|
||
|
|
data areas will appear as if you used RSTOBJ to restore them. The server does
|
||
|
|
not support the QSAVDLOALL data area.</p>
|

<p>The following table shows these
|

commands and the associated data areas:</p>
