(1) Get SERVERNUM value from onconfig:

$ onstat -c | grep SERVERNUM
SERVERNUM 2

(2) Convert SERVERNUM value from Decimal (base10) to Hexadecimal (base16):

Decimal 2 = Hex 2
= 0x2

Note: you may use ms-windows “calc” programmer view.

(3) Apply this fomular with Hexadecimal calculation:

IPC Shared Mem Address = (SERVERNUM_In_Hex * 0x10000) + 0x52564801
= (0x2 * 0x10000) + 0x52564801
= 0x20000 + 0x52564801
= 0x52584801

(4) Therefore, you will get the IPC shared memory address started from 0x52584801..

$ ipcs -m | grep 5258480
