Thread dump is invaluable to troubleshoot performance issues of SAP CPS.

You could refer to the following SAP notes to create it.

  • On SAP NetWeaver 6.40/7.0x version

710154 – How to create a thread dump for the J2EE Engine 6.40/7.0

  • On SAP NetWeaver 7.0+  version

Also, in order to keep the best performance for SAP CPS,

SAP strongly recommends installing SAP CPS on a dedicated SAP NetWeaver J2EE system,

because other productive applications (like Solution Manager, CRM, Portal, etc.) running on the same server

can cause spurious application fail-overs and performance reductions, especially on SAP NetWeaver Clusters.

It is preferred that SAP CPS is installed on single node due to the extensive use of caching in order to reduce database load

and increase performance.Only if you need the HA functions of SAP NetWeaver AS JAVA you sould install it on a dual cluster environment.

(From SAP note 1161405)

Heap dump is good for memory analysis of SAP CPS.
