<h3 id="xtune">OptiConnect performance factors</h3>
|
|
<p>Several factors can affect the performance of OptiConnect: </p>
|
|
<ul>
|
|
<li>Storage Pool
|
|
<p>OptiConnect is initially installed to use the *BASE storage
|
|
pool. You should determine if this storage pool, and the amount of storage
|
|
that is allocated in the pool, is appropriate for each system in the cluster.
|
|
Specify at least 16 MB per application system on the database system for OptiConnect.</p></li>
|
|
<li>Job Class and Priority
|
|
<p>The OptiConnect agents run under the QYYCAGNT
|
|
class in the QSOC library. The agent job class is shipped to run at priority
|
|
20; however, the job will automatically run at the same priority as its corresponding
|
|
source job.</p></li>
|
|
<li>SOCMGR Job Description, QYYCMGR
|
|
<p>As part of the job description for
|
|
the SOCMGR, the request data calls the QYYCMGR program in the QSOC library.
|
|
The parameters that are passed to the program are: </p>
|
|
<ul>
|
|
<li>The first number is the initial number of agent jobs that are started
|
|
in the agent job pool. This number includes both active and available agent
|
|
jobs. Active agents connect to a source DDM user job. Available agents are
|
|
those that are not currently connected to a user job, but are waiting to be
|
|
used. As active jobs end, the connection manager submits jobs to maintain
|
|
the number of jobs in the agent job pool. This parameter is similar to the
|
|
prestart jobs parameter that is used when starting a subsystem. When the subsystem
|
|
starts, jobs are available.</li>
|
|
<li>The second is the minimum number of available agents that are maintained
|
|
in the agent job pool. As available agents become active agents, the Connection
|
|
Manager submits jobs to maintain the number of available agent jobs. This
|
|
number should always be less than 50.</li>
|
|
<li>The third parameter value is ignored. Enter 0.</li></ul>
|
|
<p>The default parameters are (0 0 0).</p>
|
|
<p>You can adjust these
|
|
values to prestart a predetermined number of agent jobs. When a work request
|
|
comes in, it gets sent directly to an agent job that is already running or
|
|
prestarted. The number of agents should be adjusted according to the requirements
|
|
of individual installations.</p>
|
|
<p>To prestart agent jobs, change the defaults
|
|
for QYYCMGR job description. To change these values, </p>
|
|
<ol type="1">
|
|
<li>Enter:
|
|
<pre class="xmp">CHGJOBD QSOC/QYYCMGR</pre></li>
|
|
<li>Press F4, then press F10</li></ol>
|
|
<p>For the request data, change the default PARM value (0 0 0) to
|
|
the desired values.</p>
