Thanks for the info

Hi Sri,

Shared memory pools with the keys 10 and 40 pools can be configured by the parameter "ipc/shm_psize_<two-digit shared-memory id> ". Please note that these parameters cover sub memory regions, for example "System administration", "ABAP program buffer", and the other regions, under the "Shared memories inside of pool 40". So, the size of memory region that you are configuring should be as large as total size of its sub memory regions.

You can check the document for the detail information, below;

http://help.sap.com/saphelp_nw04/helpdata/en/c4/3a6f41505211d189550000e829fbbd/content.htm

I hope that it is clear.

Best regards,
