I was overwhelmed by all of you kind folks helping me with my first

attempt to migrate from SunOS to Solaris. Thank you very much for

your fast responses. I know there must be folks out there who are going

through similar "growing pain" so here's the summary of all the

good solutions I received:

My original question was:

Responses:

=======

The facility is really there, and will get loaded the first time a call

is made to create a shared memory area.

It's just that ipcs can't force it to load. Put these in the /etc/system

file:

    forceload: sys/msgsys

    forceload: sys/shmsys

    forceload: sys/semsys

    ....

Don't forget to make a backup copy of your /etc/system file

before rebooting so you have something to fall back on if your /etc/system

gets corrupted.

Reboot the system. You may need to reboot it with "boot -r" at the

monitor prompt, or:

    # reboot -- -r

OR

    # reboot "-r"

    (be sure to put double quotes to pass this option to the PROM level

     boot command)

To check the kernel for max shmem (or other settings like maxusers):

    # grep shminfo_shmmax /etc/system

    set shmsys:shminfo_shmmax=131072000

    # adb -k /dev/ksyms /dev/mem

    physmem 3fd7c

    shminfo_shmmax/D

    shminfo_shmmax:

    shminfo_shmmax: 131072000

    $q

Check "tunable parameters" in the Solaris AnswerBook for more info on

these parameters.

Once again, thanks for all of the above info.
