Tuning semaphore IPC parameters

The following table shows the parameters to be set in relation to the semaphore parameters:

Parameter	Description	Recommended Value
semmni	Maximum number of active semaphore set	Using tmboot-c command to determine the appropriate value
semmns	Maximum number of semaphores in the system	Set at least equal to MAXACCESSERS - MAXWSCLIENTS +13 (approximate number of semaphores for Tuxedo administrative servers). Using tmboot-c command to determine the appropriate value
semmnu	Number of undo structures in the system.	Since undo structure is required for each process accessing the Bulletin Board, this value must equal SEMMNS Using tmboot-c command to determine the appropriate value
semmsl	Maximum number of semaphores per semaphore set	SEMMNS / SEMMNI Using tmboot-c command to determine the appropriate value
semume	Maximum number of undo entries per undo structure.	Equal to SEMMNS Using tmboot-c command to determine the appropriate value
