(ZOS) SMF Subtype 5: J2EE container activity record (v2)
The purpose of the J2EE container activity SMF record is to record activity within a J2EE container located inside the WAS transaction server.
This record can be used to perform basic charge-back accounting, application profiling, problem determination, and capacity planning. A single record is created for each activity that is run within a J2EE container located inside a WebSphereApplication Server transaction server.
We can activate this record through the administrative console by setting server_SMF_container_activity_enabled=1 (or server_SMF_container_activity_enabled=true).
