Last updated on MARCH 15, 2018

Applies to:

PeopleSoft Enterprise PT PeopleTools - Version 8.50 to 8.55 [Release 8.4]
Information in this document applies to any platform.


This document outlines the major sources of memory consumption within a PeopleTools application server domain; primarily memory consumed by PSAPPSRV processes. In addition, discussion is provided of configuration settings that affect, and can be used to manage, memory consumption by application server domains. Some helpful tools and techniques for monitoring memory utilization are also discussed.

Note: While this document is limited primarily to PSAPPSRV process memory use, many of these concepts can also be applied other processes that run in an application server domain. For example, other processes that will execute PeopleCode and use PeopleTools are PSPUBHND and PSSUBHND.
