Poor Performing Guardrail Report
User noticed PEGA0005 ( Database query time exceeds limits) alerts related to an OOTB Report Definition - Data-Rule-Summary pzWarningsIntroduced.
This report definition gets executed mainly in the Developer Portal (for displaying rule level warnings) and can have an impact on the system performance as they on-board more and more developers and developer activity increases.
They also see huge number of PEGA0001 (Browser interaction exceeds limit) alerts which could be a direct consequence of these PEGA0005 alerts.
Steps to Reproduce
There is an outstanding performance issue with the guardrail SQL that is executed, which causes long running queries and timeouts.
Add the useLayerCakeSchemaChanges parameter to the prconfig.xml file and set it to true, this was added in ML6 and causes the SQL to executed in a more efficient manner.
