<h1 class="topictitle1">Reorganize a physical file using the Reorganize Physical File Member

|
(RGZPFM) command</h1>
|

|
<div><p>This topic outlines the uses of the Reorganize Physical File Member
|
||
|
|
(RGZPFM) command.</p>
|
||
|
|
<div class="p">You can use the RGZPFM command to: <ul><li>Remove deleted records to make the space occupied by them available.</li>
|
||
|
|
<li>Reorganize the records of a file in the order in which you normally access
|
||
|
|
them sequentially, thereby minimizing the time required to retrieve records.
|
||
|
|
This is done using the KEYFILE parameter. This might be advantageous for files
|
||
|
|
that are primarily accessed in an order other than arrival sequence. A member
|
||
|
|
can be reorganized using either of the following key fields: <ul><li>Key fields of the physical file</li>
|
||
|
|
<li>Key fields of a logical file based on the physical file</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>Reorganize a source file member, insert new source sequence numbers, and
|
||
|
|
reset the source date fields (using the SRCOPT and SRCSEQ parameters on the
|
||
|
|
RGZPFM command).</li>
|
||
|
|
<li>If you specify that the reorganize operation cannot be canceled,
|
||
|
|
reclaim space in the variable portion of the file that was previously used
|
||
|
|
by variable-length fields in the physical file format and that has become
|
||
|
|
fragmented.</li>

||
