The manual page explains the options. ipcs(1) - report inter-process communication facilities status (man pages section 1: User Commands) - Sun Microsystems

If you are unfamiliar with the IPC facilities, you will need to do some reading in order to make any sense of this. I failed to quickly uncover any single introduction which I would like to recommend (if you can borrow Stevens from the library, it's worth every kilogram) but try some of the Google hits.

They seem perfectly good to me.

Maybe if you described exactly which part you don't understand we might be able to help you.

i think if you describe your situation/problem, we can point you to a more specific document or elaborate more on what we know.

anyway, here are the tunables for ipc.
System V IPC Configuration (Solaris Tunable Parameters Reference Manual) - Sun Microsystems

if you just want to learn, you pretty much need to start reading man pages. Smilie
