Solaris 10 .

I have 98GB physical memory and
60GB SHM settings for "oracle"

i am already running 4 databases.

/usr/sbin/prtconf|grep Mem ## shows available RAM

Memory size: 98304 Megabytes

prctl -n project.max-shm-memory -i project oracle

NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
        privileged      60.0GB      -   deny                                 -
        system          16.0EB    max   deny                                 -

Can someone tell me how do i check free physical memory and
shared memory utilization(used SHM,Free shared mem).

Not a worthwhile question/exercise, since *NIX will always "consume all" available RAM.

bcm@bcm-laptop:~$ free
             total       used       free     shared    buffers     cached
Mem:       3797120    3721352      75768          0     228044    2080544
-/+ buffers/cache:    1412764    2384356
Swap:      9936888         56    9936832

>shared memory utilization(used SHM,Free shared mem).
for a close approximation just sum up the SGA sizes.
