FOREIGN or USERS Changes

If either the FOREIGN or USERS values change, change the MSGMNI kernel parameter using the following formula. This formula produces the setting required by Lawson. The new value for MSGMNI equals the sum of the old value for MSGMNI plus the setting required by Lawson.

MSGMNI = (FILES / LFILES) + FOREIGN + USERS + 25
Note: 

In Solaris 10, the MSGMNI parameter were replaced by process.max-msg-ids.

Example

Assume the following:

  • MSGMNI is 300.

  • Lawson is installed (for the first time).

  • USERS and FOREIGN are set to 500 (125 users).

  • FILES is set to 1500.

  • LFILES is 9.

The Lawson requirement for MSGMNI is FILES/LFILES + FOREIGN + USERS + 25 = 1500/9 + 500 + 500 + 25 = 1192

MSGMNI needs to be set to 300 + 1192 = 1492.
