Performance degrades on performing any action in Designer Studio

SA-77900

Summary



Performance degrades while performing any operation in Designer Studio.


Error Messages



com.pega.pegarules.pub.context.RequestorLockException: Unable to synchronize on requestor HU2RN6VAUVISGFBYRGGCOMVE65FD0SFR5A within 120 seconds: (thisThread = WebContainer : 10) (originally locked by = WebContainer : 8) (finally locked by = WebContainer : 8)


Steps to Reproduce



Open Designer Studio and perform any action.


Root Cause



The PEGA0101 alert is generated when a queue processor fails because of a missing or failed stream node. The stream node is not available in the cluster and as a result, all the threads are in the waiting state concluding in the occurrence of the exception.


Resolution

Perform the following local-change: 
  1. Add a new stream node to avoid Pega0101 alerts
  2. Set one of the nodes to be universal. A universal node supports both the Decision Strategy Manager (DSM) Stream Service and Queue Processor rules. Use the below setting to configure the node:
    DNodeType=Universal
