Kernel Parameter Adjustments

Some kernel parameters require adjusting when you change the FOREIGN or USERS values in the ladb.cfg file.See your system documentation for the location of the kernel tuning parameters for your specific platform.

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.
For example, assume these items:

  • 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.
