Lightbulb How to relate ipcs id or cpid to process?
Hi,
we have multiple database instances running on solaris server like db1, db2 and db3. Below shown ipcs -pmb shared memory segment output. Using cpid value I want to relate to the database instances db1, db2 and db3. Please let me know how to do this?

Code:
$ ipcs -pmb

Does the PID in the CPID or LPID columns in the ipcs output show up in the PID column of the output from ps -lea? If so, does the database instance show up in the CMD column output on any of those lines?

i don't see any of these CPID's.

Code:
$ ps -lea | grep 27760
$ ps -lea | grep 13405
$ ps -lea | grep 11641

But I see one CPID process (14393) from ipcs output as shown below.


Code:
m         32   0xb2e13204 --rw-rw----   oracle      dba       8192 28257 21677

m         30   0          --rw-rw----   oracle      dba  352321536 28257 21677
m         29   0          --rw-rw----   oracle      dba  704643072 28257 21677

m         25   0          --rw-rw----   oracle      dba 5704253440 14393 26867
m         24   0          --rw-rw----   oracle      dba 5704253440 14393 26867
m         23   0          --rw-rw----   oracle      dba 6643777536 14393 26867

Code:
$ ps -lea | grep 14393
 0 S  10000 14393     1   0  40 20        ? 262276        ? ?         200:28 oracle

The CPID & LPID are Create and Last attach/detach Process ID. The processes may no longer exist.
