<h1 class="topictitle1">Use the precheck option</h1>
|
||
|
|
<div><p>Use the precheck option explains how to have the server check certain
|
||
|
|
criteria on each object that you save on a library-by-library basis. This
|
||
|
|
option is not required.</p>
|
||
|
|
<p>You can use the precheck (PRECHK) parameter when you save objects to ensure
|
||
|
|
that all of the objects you intend to save can be successfully saved. If you
|
||
|
|
specify <samp class="codeph">PRECHK(*YES)</samp>, the server verifies that the following
|
||
|
|
are true of each object that you are saving on a library-by-library basis:</p>
|
||
|
|
<ul><li>The object can be allocated during the save operation. No other job has
|
||
|
|
a conflicting lock on the object.</li>
|
||
|
|
<li>The object exists.</li>
|
||
|
|
<li>The object is not marked as damaged. The precheck process looks only for
|
||
|
|
damage that has already been detected. It does not detect new damage to the
|
||
|
|
object header or damage to the contents.</li>
|
||
|
|
<li>All members of an object can be allocated if the object is a database
|
||
|
|
file.</li>
|
||
|
|
<li>The person that requests the save operation has sufficient authority to
|
||
|
|
save the object.</li>
|
||
|
|
</ul>
|
||
|
|
<p>When you specify PRECHK(*YES), all of the objects you are saving in a library
|
||
|
|
must meet the conditions. If they do not, no objects in the library are saved.
|
||
|
|
If you specify more than one library on the save command, the failure of one
|
||
|
|
library to meet the PRECHK tests does not typically prevent the server from
|
||
|
|
saving other libraries. However, if you specify SAVACT(*SYNCLIB),
|
||
|
|
the entire save operation stops if one object fails the precheck process.</p>
|
||
|
|
<p>When you specify PRECHK(*NO), the server performs the checking on an object-by-object
|
||
|
|
basis. The server bypasses any object that does not meet the conditions, but
|
||
|
|
the save operation continues with other objects in the library.</p>
