Goal

Tuning SHMMIN IPC Kernel Parameter may prevent Tuxedo/Domain to boot.

SHMMIN is an IPC kernel parameter imposing a minimum size to each shared memory segment created by a process. The default value is 1 and tuning this parameter to another value will impose additional requirement on each shared memory segment created in the system. If you tune this value, your Tuxedo application may not boot at all or each GWADM processes may fail to boot with the following error message:

LIBGW_CAT:3017: ERROR: Can't create initial shared memory segment(s)
