<h1 class="topictitle1">Database file recovery during the IPL</h1>
|
|
<div><p>During the initial program load (IPL), nothing but the recovery
|
|
function is active on the system.</p>
|
|
<p>Database file recovery during the IPL consists of the following
|
|
actions:</p>
|
|
<ul><li>The listed functions that were in progress when the system ended are completed: <ul><li>Delete file</li>
|
|
<li>Remove member</li>
|
|
<li>Rename member</li>
|
|
<li> Move object</li>
|
|
<li> Rename object</li>
|
|
<li>Change object owner</li>
|
|
<li>Change member</li>
|
|
<li>Grant authority</li>
|
|
<li>Revoke authority</li>
|
|
<li>Start journal physical file</li>
|
|
<li>Start journal access path</li>
|
|
<li>End journal physical file</li>
|
|
<li>End journal access path</li>
|
|
<li>Change journal</li>
|
|
<li>Delete journal</li>
|
|
<li>Recover SQL views</li>
|
|
<li>Remove physical file constraint</li>
|
|
</ul>
|
|
</li>
|
|
<li>The listed functions that were in progress when the system ended are backed
|
|
out (and you must run them again): <ul><li>Create file</li>
|
|
<li>Add member</li>
|
|
<li>Change file</li>
|
|
<li>Create journal</li>
|
|
<li>Restore journal</li>
|
|
<li>Add physical file constraint</li>
|
|
</ul>
|
|
</li>
|
|
<li>If the operator is doing the IPL (attended IPL), the Edit Rebuild of Access
|
|
paths display appears on the operator's display. The display allows the operator
|
|
to edit the RECOVER option for the files that were in use for which immediate
|
|
or delayed maintenance was specified. If all access paths are valid, or the
|
|
IPL is unattended, no displays appear.</li>
|
|
<li>Access paths that: <ul><li>have immediate or delayed maintenance</li>
|
|
<li>are specified for recovery during IPL (from the RECOVER option or changed
|
|
by the Edit Rebuild of Access Paths display)</li>
|
|
<li>are rebuilt and a message is sent when you start journaling your access
|
|
paths. Placing journal receivers in their own user auxiliary storage pool
|
|
provides the best journaling performance, while helping to protect them from
|
|
a disk failure. </li>
|
|
</ul>
|
