<h1 class="topictitle1">Method of allocating storage</h1>
|

|
|
<div><p>The CONTIG parameter controls the method of allocating physical
|
||
|
|
storage for a member (CRTPF and CRTSRCPF commands). </p>
|
||
|
|
<div class="p"> If you allocate storage, you can request that the storage for the starting
|
||
|
|
record count for a member be contiguous. That is, all the records in a member
|
||
|
|
are to physically reside together. If there is not enough contiguous storage,
|
||
|
|
contiguous storage allocation is not used and an informational message is
|
||
|
|
sent to the job that requests the allocation, at the time the member is added. <div class="note"><span class="notetitle">Note:</span> When
|
||
|
|
a physical file is first created, the system always tries to allocate its
|
||
|
|
initial storage contiguously. The only difference between using CONTIG(*NO)
|
||
|
|
and CONTIG(*YES) is that with CONTIG(*YES) the system sends a message to the
|
||
|
|
job log if it is unable to allocate contiguous storage when the file is created.
|
||
|
|
No message is sent when a file is extended after creation, regardless of what
|
||
|
|
you specified on the CONTIG parameter.</div>
