How to Tune the Interprocess Communication Parameters

1. Become superuser.

2. Add a line to the /etc/system file using the syntax described in Table 66-4.

   Table 66-4 Tuning Interprocess Communication Parameters

   Parameter Type	Parameter	Tuning Syntax
   Message Queue	msgsys	set msgsys:msginfo_variable = value
   Semaphore Facility	semsys	set semsys:seminfo_variable=value
   Shared Memory	shmsys	set shmsys:shminfo_variable=value

3. Verify the kernel parameter change.

   # grep parameter /etc/system

4. Reboot the system.

   The kernel parses the /etc/system file during autoconfiguration and overrides the default value for the parameters specified in this file.
