hi experts,

one of applicatin server most of the workprocess have been stopped due to reason PRIV mode. I killed the session of some users but the problem persisting again.

please suggest

Hi Sudhakar,

unfortunately we are not the experts for your questions. I would assume that the [general NetWeaver forum|; has a much better audience for your question. This forum is about Java memory analysis.

HI

Ideally there should not be any work process running in the PRIV (or the PRIVATE ) mode as this consumes the shared system memory and affects the performance of the system. The work process in such a mode enters the HEAP memory of the user. Please refer to memory management for this as discussed above.

Also, if possible, please kill such a process with confirmations from the user.OR even better, ask the user himself to logout of the system and log back in.Such activities would release the memory resources occupied by such a WP

To kill such a process..Run SM66

Goto Edit Tab > Process>Restart after error --> yes (in case its No)

Then again Edit Tab --> Process --> cancel --> without core

Hi,

When a a WP enters in PRIV mode is because it is using Heap Memory, as this memory is shared the WP must finish its process so the memory can be cleared. The problem is that either Extended memory is not enough or the program takes too much memory, if the problem happens in any standard program then you should define more Extended memory, if the problem only happens during customized programs then the problem is surely a programing error.

Good luck

Hi Sudhakar,

Have a look at the following link, it will explain you about memory management

http://help.sap.com/saphelp_45b/helpdata/en/02/9625e3538111d1891b0000e8322f96/frameset.htm

Hope this helps you a lot.

Please check the memory parameters like ,

abap/heap_area_dia

abap/heap_area_nondia

abap/heap_area_total

abap/heaplimit

and check the recommendations ( RZ11 ) and increase to 2000000000 (UNIX) if u have high memory requirements and more concurrent users doing heavy tasks.

These thresholds can be determined with

the test program 'memlimits'

In SM50 select each work process with PRIV, make sure restart after error is enabled and then cancel each process without core. This will basically restart the work process and work process PRIV mode will be gone. The reason it is in PRIV mode is because some user muste have used heam memory of thw work process. There fore until that memory is cleared, the work process will only server that user only. By canceling and restarting the process you create the heap
