resource services provides a set of control language (CL) commands, application
|
||
|
|
program interfaces (APIs) and facilities that can be used by iSeries™ application
|
||
|
|
providers or customers to enhance their application availability.</p>
|
||
|
|
<p>You can write your own custom application to configure and manage your
|
||
|
|
cluster by utilizing cluster control language (CL) commands and application
|
||
|
|
programming interfaces (APIs). These commands and APIs take advantage of the
|
||
|
|
technology provided by cluster resource services provided as a part of <span class="keyword">i5/OS</span>.</p>
|
||
|
|
<dl><dt class="dlterm">QUSRTOOL</dt>
|
||
|
|
<dd>Cluster resource services also provides a set of example commands in the
|
||
|
|
QUSRTOOL library that map to the APIs that have no supported command interface.
|
||
|
|
The QUSRTOOL commands might be useful in some environments. For example, you
|
||
|
|
can change heartbeating or send information around the cluster. See the member
|
||
|
|
TCSTINFO in the file QUSRTOOL/QATTINFO for more information about these example
|
||
|
|
commands. An example application CRG exit program is also included in the
|
||
|
|
QUSRTOOL library. The sample source code can be used as the basis for writing
|
||
|
|
an exit program. Sample source, TCSTDTAEXT, in file QATTSYSC contains a source
|
||
|
|
for a program to create the QCSTHAAPPI and QCSTHAAPP0 dataareas, and QACSTOSDS
|
||
|
|
(object specifier) file.</dd>
