Post update, prlogging.xml or prlog4j2.xml is missing



Post update to Pega 7.3.0, prlogging.xml or prlog4j2.xml are missing. Hence, Pega logs are not generated in the directory of choice.

Error Messages

Not Applicable

Steps to Reproduce

  1. Update Pega 7.1.7 to Pega 7.3.0
  2. Modify prlog4j2.xml (or prlogging.xml) and update Pega appender with the environment variable that is defined in an application server and points to the directory of choice.

    <RollingRandomAccessFile  name="PEGA" fileName="${your.log.path}/PegaRULES.log" filePattern="${your.log.path}/PegaRULES-%d{MM-dd-yyyy}-%i.log.gz">

Root Cause

The System environment variable was not prefixed with 'sys:'.


Update prlog4j2.xml Pega appender to use the 'sys:' prefix.

<RollingRandomAccessFile  name="PEGA" fileName="${sys:your.log.path}/PegaRULES.log" filePattern="${sys:your.log.path}/PegaRULES-%d{MM-dd-yyyy}-%i.log.gz">
