Hi Krishna,

What is your OS and DB ?

Please run SAPPFPAR check and fix the value provided by too. Refer to below guide on how to perform that and also check values

abap/heap_area_dia

abap/heap_area_nondia

abap/heap_area_total

abap/heaplimit

If Windows, check the note for Zero Administration values

Note 88416 - Zero administration memory management for the ABAP server

Hi Krishna,

In addition to the parameter you have mentioned check these parameter as well in the system.

A process going into PRIV means that either it has exhausted its quota of extended memory (ztta/roll_extension) or that the total extended memory (em/initial_size_MB) has been used up by other sessions.So increase these 2 parameter to start with and then tune others.

rdisp/ROLL_SHM 32768 8 kB Part of roll file in shared memory

rdisp/PG_SHM 16384 8 kB Part of paging file in shared memory

rdisp/PG_LOCAL 150 8 kB Paging buffer per workprocess

em/initial_size_MB 61440 MB Initial size of extended memory

em/blocksize_KB 4096 kB Size of one extended memory block

em/address_space_MB 4096 MB Address space reserved for ext. mem. (NT only)

ztta/roll_extension 2000000000 Byte Max. extended mem. per session (external mode)

abap/heap_area_total 64424500000 Byte Max. usable heap memory

abap/heaplimit 40000000 Byte Workprocess restart limit of heap memory

Also,consider setting rdisp/wppriv_max_no and rdisp/max_priv_time,so that system performance is not much impacted.

Hi,

As mentioned increase the size of parameters ztta/roll_extension and em/initial_size_MB

U can also restrict the no of dialog wp going into PRIV mode by using parameter rdisp/wppriv_max_no

u Can also use rdisp/max_priv_time to reset the wp from PRIV mode
