|
<div><p>Use catalog shadowing to create a copy of an existing image catalog. </p>
|
||
|
|
<p>Use the Create Image Catalog (CRTIMGCLG) command to create a copy of an
|
||
|
|
image catalog. The reference image catalog contains information about images.
|
||
|
|
The dependent image catalog is a copy of the reference image catalog at a
|
||
|
|
single point in time when the Create Image Catalog (CRTIMGCLG) command was
|
||
|
|
performed.</p>
|
||
|
|
<div class="p">Use this command to create a dependent image catalog of your reference
|
||
|
|
catalog:<pre>CRTIMGCLG IMGCLG(<em>dependent</em>) DIR(*refimgclg) REFIMGCLG(<em>reference</em>)</pre>
|
||
|
|
</div>
|
||
|
|
<p>There can be up to 35 ready dependent catalogs pointing to one reference
|
||
|
|
catalog. Each of the tape reference catalogs are read only and write accessible.
|
||
|
|
However optical reference and all dependent image catalogs are read-only and
|
||
|
|
can be used for restore operations.</p>
|
||
|
|
<p>In order to delete the reference catalog or to delete any one image file
|
||
|
|
all of the dependent image catalogs must be deleted first. The volume name
|
||
|
|
for the optical dependent catalogs has a four character prefix. The prefix
|
||
|
|
is added once the optical dependent catalog is made ready. Use the Work with
|
||
|
|
Image Catalog Entries (WRKIMGCLGE) to find the optical dependent
|
||
|
|
volume name.</p>
