Improved Agent Session Life-Cycle Management in PAS for OpenEdge

Prior to OpenEdge 12.7 release, a PAS for OpenEdge System Administrator had to configure a multi-session PAS for OpenEdge agent to automatically scale up and add more sessions to handle more concurrent requests. However, there was no provision to automatically scale down or trim the excess ABL sessions when they were no longer necessary or had reached an age limit or memory limit. System Administrators sometimes addressed this issue by creating a monitoring process to identify and trim the ABL sessions when they were no longer required.

From OpenEdge 12.7 release onwards, new properties are added to the openedge.properties file, which allow the System Administrator to configure a PAS for OpenEdge instance to scale down the excess ABL sessions by trimming them when they are no longer necessary or have reached an age limit or memory limit.

For more information, refer to ablSessionActiveMemoryLimitFinish, ablSessionActiveMemoryLimitStop, ablSessionMemoryLimit, ablSessionMemoryDump, ablSessionFailureLimit, and ablSessionRequestLimit properties in Configure OpenEdge properties.
