<h4 id="rzalusplfstorage">Spooled file library</h4>
|
||
|
|
<p>The spooled file library (QSPL or QSPL<span class="italic">xxxx</span>, where <span class="italic">xxxx</span> is the number of the basic user ASP or primary independent
|
||
|
|
ASP) contains database files that are used to store data for inline data files
|
||
|
|
and spooled files. Each file in library QSPL or QSPLxxxx can have several
|
||
|
|
members. Each member contains all the data for an inline data file or spooled
|
||
|
|
file.</p>
|
||
|
|
<p>When the spooled file is printed or deleted, its associated database member
|
||
|
|
in the spooling library is cleared of records, but not removed, so that it
|
||
|
|
can be used for another inline data file or spooled file. If no database members
|
||
|
|
are available in library QSPL or QSPLxxxx, then a member is automatically
|
||
|
|
created.</p>
|
||
|
|
<p>Having some empty spooled file members available for creating new spooled
|
||
|
|
files increases system run-time performance. However, a large number of empty
|
||
|
|
spooled files can use large amounts of storage and decrease system abnormal
|
||
|
|
IPL performance. For example, each spooled file member might take 24 KB of
|
||
|
|
storage.</p>
|
||
|
|
<p>It is best to keep the QSPL or QSPLxxxx library small by periodically deleting
|
||
|
|
old spooled files with the DLTSPLF or CLROUTQ commands. This procedure allows
|
||
|
|
database members to be used again, rather than having to increase the size
|
||
|
|
of the spooling library to accommodate new database members.</p>
|
||
|
|
<p>See <a href="rzalureclaimsplf.htm#rzalureclaimsplf">Reclaim spooled file storage</a> for more information on how to remove
|
||
|
|
spooled database members. This is the only allowable way to remove spooled
|
||
|
|
database members from the QSPL or QSPLxxxx library. Any other way can cause
|
||
|
|
severe problems.</p>
|
||
|
|
<p>Displaying the data in the QSPL or QSPLxxxx library might prevent the data
|
||
|
|
from being cleared, wasting storage space. Any command or program used to
|
||
|
|
look at a database file in the QSPL or QSPLxxxx library must allocate the
|
||
|
|
database file and member; if a writer tries to remove an allocated member
|
||
|
|
after printing is completed, it will not be able to clear the member. Because
|
||
|
|
the member is not cleared, it cannot be used for another inline data file
|
||
|
|
or spooled file, and it will not be removed by setting the Automatically clean
|
||
|
|
up unused printer output storage (QRCLSPLSTG) system value or running the
|
||
|
|
RCLSPLSTG command.</p>
|
||
|
|
<p>Saving a database file in the QSPL or QSPLxxxx library can cause more problems
|
||
|
|
than displaying the data in one member of the file because all members will
|
||
|
|
be allocated a much longer time when a database file is saved. Because restoring
|
||
|
|
these files destroys present and future spooled file data, there is no reason
|
||
|
|
to save one of these files.</p>
|
||
|
|
<p>The QSPL or QSPLxxxx library type and authority should not be changed.
|
||
|
|
The authority to the files within QSPL or QSPLxxxx should also not be changed.
|
||
|
|
The QSPL or QSPLxxxx library and the files in it are created in a particular
|
||
|
|
way so that server spooling functions can access them. Changing the library
|
||
|
|
or files could cause some server spooling functions to work incorrectly and
|
||
|
|
destroys the integrity of the spooled file security scheme.</p>
