|
|
<p>The Reclaim Object Links (RCLLNK) command allows a single object or a group of objects to be reclaimed.
|
|
</p>
|
|
<p>The RCLLNK command can be used to reclaim a directory tree where the directory, its contents, and the contents of all of its subdirectories are reclaimed. A subtree reclaim will attempt to reclaim as many objects as possible. A diagnostic message will be sent for each object that cannot be reclaimed. Additionally, an informational message will be sent if a specific problem is corrected, or a diagnostic message will be sent if a specific problem is unable to be corrected. If all of the objects have been reclaimed, with all of the problems corrected, then a completion message will be sent. Otherwise, an escape message will be sent.
|
|
</p>
|
|
<p>The RCLLNK command does the following:
|
|
</p>
|
|
<ul>
|
|
<li>Corrects object user profile problems
|
|
</li>
|
|
<li>Corrects user-defined file system problems
|
|
</li>
|
|
<li>Corrects internal object problems
|
|
</li>
|
|
<li>Removes invalid object links
|
|
</li>
|
|
<li>Handles damaged objects as specified on the <b>Damaged object option (DMGOBJOPT)</b> parameter
|
|
</li>
|
|
<li>Creates missing system objects
|
|
</li>
|
|
</ul>
|
|
<p>A full Reclaim Storage (RCLSTG) fixes the above problems, as well as others such as lost objects or problems which require the system to be in a restricted state. Unlike RCLSTG, the system does not have to be in a restricted state to run RCLLNK.
|
|

|
|
</p>
|
|
<p><b>Restrictions:</b>
|
|
</p>
|
|
<ul>
|
|
<li>You must have all object (*ALLOBJ) special authority to run this command.
|
|
</li>
|
|
<li>Only objects found in the "root" (/), QOpenSys, or mounted user-defined file systems are eligible to be reclaimed. All other objects are ignored during a subtree reclaim.
|
|
</li>
|
|
<li>An independent auxilary storage pool (ASP) must have a status of "Available" in order for objects residing on the independent ASP to be reclaimed.
|
|
</li>
|
|
<li>Storage freed objects are not reclaimed unless a storage freed object is specified on the <b>Object (OBJ)</b> parameter.
|
|
</li>
|
|
<li>Objects that are being saved or restored cannot be reclaimed.
|
|
</li>
|
|
<li>An object's last access, data change, and attribute change date and time values are not normally updated as a result of being reclaimed. However, if the object has a problem that is corrected, these values may be updated.
|
|
</li>
|
|
<li>Problems found in the contents of a damaged directory object are not corrected.
|
|
</li>
|
|
<li>The directory conversion function must not be active while RCLLNK runs. The Convert Directory (CVTDIR) command with OPTION(*CHECK) can be used to verify directory conversion is not active.
|
|
</li>
|

<h3>Object (OBJ)</h3>
|
|
<p>Specifies the path name of the object to be reclaimed. The object must be in the "root" (/), QOpenSys, or a user-defined file system. The object path name can be either a simple name or a name that is qualified with the name of the directory in which the object is located. A pattern cannot be specified ('*' or '?'). If the path name is qualified, it must be enclosed in apostrophes.
|
|
</p>
|
|
<p>RCLLNK will not follow symbolic links for the last component in the path name.
|
|
</p>
|
|
<p>If the last component in the path name is a block special file (*BLKSF) then only the block special file object will be reclaimed, not the user-defined file system that it represents.
|
|
</p>
|
|
<p>The last component name in the path name cannot be '.' (dot) or '..' (dot-dot).
|
|
</p>
|
|
<p>The effective root directory must be the "root" (/). Refer to the i5/OS PASE chroot command in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter for more information.
|
|
</p>
|
|
<p>For more information on specifying path names, refer to "Object naming rules" in the CL concepts and reference topic in the iSeries Information Center at http://www.ibm.com/eserver/iseries/infocenter.

<h3>Damaged object option (DMGOBJOPT)</h3>
|
|
<p>Specifies how damaged objects are handled that are considered <b>usable</b> or <b>unusable</b>. If no operations can be performed on a damaged object it is considered unusable. Otherwise, it is considered usable.
|
|
</p>
|
|
<p>Deleting a usable damaged directory object will cause all its contents and the contents of all its subdirectories to become lost. These lost objects will need to be restored from media or can be recovered via a RCLSTG. The contents of an unusable damaged directory object are already lost.
