System performance degrades in server due to PEGA0101 alert
SA-76706
Summary
System performance degrades even when only one requestor is logged in.
Error Messages
PEGA0101 alert
Steps to Reproduce
Not Applicable
Root Cause
The performance degraded due to the following:
- PEGA0101 alert was generated when a queue processor failed due to a missing or failed stream node. The stream node is unavailable in the cluster.
- The Decisioning Stream Service was required to be running for the Queue Processors. If the Stream Service was not running, the Queue Processors would not be able to Start.
- The DType argument was not set for the node.
- The pg was empty after the db.open error was present in the log.
Resolution
Perform the following local-change:
- Add a new stream node to avoid PEGA0101 alerts.
- If there is only one node, set it as universal. A universal node supports both the Decision Strategy Manager (DSM) Stream Service and Queue Processor rules.
For example, use the below setting:
-DNodeType=Universal
- pg is empty after db.open.
