How to detect when the wait time for rule assembly cache access has exceeded a threshold (PEGA0038 alert)

The alert indicates that a requestor's wait time to access to the rule assembly cache has exceeded a threshold.

Alert log message

Cache find synchronization time has exceeded threshold of 30 ms: 856 ms. Details: Total find time:
             ELAPSED time = 1,712;
             Synchronization time = 856;
             Caller ActivityClassName = ;
             Caller ActivityRuleSet time = ;
             aFUA Aspect = Action;
             aFUA Identification = Rule-Obj-Activity
             Code-.SystemIndexer;aFUA Defining Class = Rule-Obj-Activity

Modifying the alert settings

You can modify the default settings in the alerts section of the prconfig.xml file, as follows:

1. Open the prconfig.xml file and update these alerts sections:

enabled

<env name = “alerts/fua/synchtime/enabled" value="true" />

The enabled value is a boolean. To turn off the alert, change the value to "false".

threshold

<env name = “alerts/fua/synchtime/threshold" value="30" />

The threshold value is a positive integer in milliseconds (default is 30 ms).

2. Stop and restart the server.

Next steps

This alert indicates system loading issues. Related PEGA0037 and PEGA0001 alerts are likely, which merit investigation. Excessive cache synchronization times lead to longer assembly and interaction times.
