In distributed data flow or simulation runs, the topology configuration determines how many nodes participate in the pool that is used to distribute the run and the number of threads per node. The number of threads is determined by the agent/threadpoolsize and services/maxrequestorchildren environment settings that you configure in the prconfig.xml file.
Open the prconfig.xml file from the application server.
Add the following configuration:
<env name="agent/threadpoolsize" value="xx" />
<env name="services/maxrequestorchildren" value="xx" />
For the xx value, you can select up to 10 threads.
Save your changes and upload the prconfig.xml file to the application server.
