<div><p>The Override with Database File (OVRDBF) command can override a
|
||
|
|
local database file with a remote VSAM data set.</p>
|
||
|
|
<div class="section"><p>However, the following items must be considered: </p>
|
||
|
|
<ul><li>A POSITION value of *RRN works when the remote VSAM data set is an RRDS.
|
||
|
|
For all other types of VSAM data sets, *RRN causes a server message on the <span class="keyword">iSeries™</span> server.</li>
|
||
|
|
<li>A POSITION value of *KEYB or *KEYBE causes a server message on the <span class="keyword">iSeries</span> server when the remote file
|
||
|
|
is a VSAM path.</li>
|
||
|
|
<li>Unless the CICS<sup>®</sup> system
|
||
|
|
programmer replaces the CICS/DDM-supplied exclusive file lock program, the
|
||
|
|
RCDFMTLCK parameter must have a lock condition value of *SHRRD or *SHRUPD.
|
||
|
|
All other lock condition values result in a server message on the <span class="keyword">iSeries</span> server.</li>
|
||
|
|
<li>CICS/DDM does not return the actual expiration date of the file to <span class="keyword">i5/OS™</span> DDM. Instead, it returns a
|
||
|
|
special value that indicates the expiration date is not known. This is true
|
||
|
|
even if the EXPCHK parameter has a value of *YES.</li>
