Short version:
Main problem is it seems prctl for process.max-sem-nsems is not working.
When I do a prctl $$ I see the kernel parameter set, but when specifying it on the command line it doesn't think it exists (?)
Detailed version:
Going through the oracle 10 pre-installation config tasks on solaris 10, I see the kernel settings which need to be set:
noexec_user_stack 1 (/etc/system)
project.max-sem-ids 100
process.max-sem-nsems 256
project.max-shm-memory 4294967295
project.max-shm-ids 100
I added the kernel settings to all the projects also just because I'm over paranoid even though oracle is using user.oracle by default.
Anyway, all seem fine except for process.max-sem-nsems. I get an error when trying to prctl it.

Any idea what's going on?
