<div><div class="section"><p>You can use the Work With Forward Recovery display to perform
|
|
the following tasks:</p>
|
|
<dl><dt class="dlterm">Add object to list</dt>
|
|
<dd><img src="./delta.gif" alt="Start of change" />To add an object to the list on the display, use Option 1 (Add
|
|
member to list). Do this if you want to restore those objects. This task is
|
|
not available for Integrated File System objects.<img src="./deltaend.gif" alt="End of change" /></dd>
|
|
<dt class="dlterm">Apply journaled changes</dt>
|
|
<dd><img src="./delta.gif" alt="Start of change" />To apply journaled changes to an object, use Option 2 (Apply
|
|
journaled changes). This option applies journaled changes and changes the
|
|
status to Recovered (if the apply operation was successful). If the apply
|
|
operation was not successful, messages appear indicating why and the last
|
|
successful status is displayed. If any required receivers are missing or damaged
|
|
while running the <span class="cmdname">APYJRNCHG</span> command, the system prompts
|
|
for the restore of the missing or damaged receivers.<p>If any of the objects
|
|
in the list have a status of Damaged, the system prompts you with the command
|
|
necessary to recover the object. For objects that are damaged, recovery involves
|
|
deleting the object, a restore of the last save of the object, followed by
|
|
the <span class="cmdname">Apply Journaled Changes (APYJRNCHG)</span> command. The system
|
|
guides you through the recovery of physical files as follows:</p>
|
|
<div class="note"><span class="notetitle">Note:</span> <img src="./delta.gif" alt="Start of change" />The
|
|
recovery is similar for data areas, data queues, and integrated file system
|
|
objects, except for the dependent logical files references. Also, the restore
|
|
command names are different for integrated file systems it is RST, but for
|
|
all others its RSTOBJ.<img src="./deltaend.gif" alt="End of change" /></div>

|
|
</dl>
|

</div>
|
|
<ol><li><span><img src="./delta.gif" alt="Start of change" />For physical files, the system identifies all the logical

files dependent on the specified damaged file. The Dependent Logical Files

display appears identifying these files.<img src="./deltaend.gif" alt="End of change" /></span></li>
|

<li><span>The dependent logical files are deleted.</span></li>
|

<li><span>The system deletes the files to be recovered (or restored).</span></li>
|
|
<li><span>The system displays prompts for the restore of files to be recovered.
|
|
After all restores are completed successfully, the files to be recovered are
|
|
allocated exclusively to prevent any other processing. This allocation is
|
|
maintained until the recovery procedures are complete.</span></li>
|
|
<li><span>The system displays prompts for the restores of the dependent logical
|
|
files.</span></li>
|
|
<li><span>An APYJRNCHG command is prompted.</span></li>
|
|
<li><span>If the APYJRNCHG command encounters a required journal receiver
|

that is not online, the system prompts for the restore of the required receiver

and again starts the APYJRNCHG command.</span></li>

</ol>

<div class="section"><p>When the recovery process is complete, the status field for the

|
|
<dd><img src="./delta.gif" alt="Start of change" />If you wish to restore any objects, use Option
|
|
3 (Restore). This is particularly useful for objects with a status of Not
|
|
Found. Objects that are restored successfully have a status of Restore Complete.
|
|
Objects that are not restored keep their old status. A message is sent indicating
|
|
that the restore did not complete successfully. All objects that are restored
|
|
are included in the list of objects to recover.<div class="note"><span class="notetitle">Note:</span> The last save information
|
|
is provided for the restore operation. If either of the following are true,
|
|
then you must use the RSTOBJ command instead of Option 3 (Restore): <ul><li>The device provided is tape, diskette, or optical and you choose to restore
|
|
from a save file (*SAVF).</li>

<li>The device provided is a save file (*SAVF) and you choose to restore from

tape, diskette, or optical media.</li>
|

</ul>
|
|
</div>
|
|
<div class="p"><img src="./delta.gif" alt="Start of change" />If you choose option 3 to restore a damaged object,
|
|
the restore process involves deleting the object prior to prompting to restore
|
|
the object. The process is similar for all object types except there are extra
|
|
steps if restoring damaged physical files that have dependent logical files.
|
|
The system guides you through the restore process of damaged physical files
|
|
as follows: <ul><li>The system identifies all the logical files dependent on the specified
|
|
damaged physical file.</li>
|
|
<li>The Dependent Logical Files display appears identifying these logical
|
|
files.</li>
|
|
<li>The system deletes the files to be restored.</li>
|
|
<li>The system then prompts with a restore command for the physical files. </li>
|
|
<li>Once the physical files are restored, the system prompts with a restore
|
|
command to restore the logical files.</li>
|
|
</ul>
