Is PegaRULES logs stored in any table, so that we can execute DB script to delete (or) the server administrator has to manually delete the PegaRULES logs from folders? Please share if you have any table details or sample scripts.
prlogging.xml controls the generation of PegaRULES.log. You can change the rollover policies, filenames, locations etc.. but we can't use it for deletion.
PegaRULES logs will be stored in server filesystem only as defined in prlogging.xml. You check over the web to get sample shell scripts to tar/gzip the logs to move it some other disk or remove if not needed.
