Managing requestors

From the Requestor Managment landing page, you can manage active requestors from a cluster-based or node-based view to debug any problems with requestor activity.

To access the Requestor Management landing page, view performance, and trace entry details, you must have the pzSystemOperationsObserver privilege. To perform most actions on requestors, you must also have pzSystemOperationsAdministrator privilege. To trace requestors and view the clipboard, you must also have the pzDebugRemoteRequestor privilege.

1. Click Designer Studio > System > Operations > Requestor Management.
2. Click the Cluster tab to manage requestors in a specific cluster, or click the Node tab to manage requestors on a specific node.
3. In the Actions column, click the Actions link that corresponds to the requestor that you want to manage, and select one of the following options.
   • Performance details – Select this option to view the Performance Analyzer (PAL) statistics for the selected requestor.
   • Trace – Select this option to start the Tracer tool for the selected requestor to debug errors in requestor activity.
   • Terminate Trace – Select this option to stop the Tracer tool for requestors for which the tracing session was not properly closed, for example, because of network issues.
   • Trace Entry Details – Select this option to view a Java stack trace of the operations performed by the selected requestor. This snapshot display is not updated in real time. Access is denied if the default security properties file is still in effect.
   • View Clipboard – Select this option to open the Clipboard tool for the selected requestor to review property values that are in the clipboard.
   • Analyze Clipboard – Select this option to view the estimated clipboard size in kilobytes and the size of each thread and clipboard page for the selected requestor.
   • Interrupt – Select this option to interrupt the processing of the selected requestor at the beginning of the next activity step.
   • Terminate – Select this option to stop the requestor, remove it from the requestor status display, and delete it from the system.
   • Start Profiling / Stop Profiling – Select this option to start or stop profiling the selected requestor. After stopping the Profiler tool you can download the .csv file that contains a detailed trace of performance information for the selected requestor.
   • Requestors Details – Select this option to view details for the selected requestor, including the operator name, ID, and a trace list. Set the trace/requestorlistsize prconfig setting to any value between 0 and 511 inclusive, to configure the number of trace entries that can be viewed.
