Solaris 10 kernel tuning

Solaris 10 kernel tuning

Solaris 10 kernel tuning


I'm attempting to increase a kernel parameter on the fly using prctl and it's failing with the below error message. Can anyone advise on what I'm doing wrong and how to fix this issue?

id -p
uid=400(arbor) gid=200(arboradm) projid=3(default)
fpfeuska% prctl -n project.max-msg-ids -i project 3
project: 3: default
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
        privileged        128       -   deny                                 -
        system          16.8M     max   deny                                 -
fpfeuska% prctl -n project.max-msg-ids -r -v 10k -i project 3

prctl: cannot set process privileges for pid 7953: Not owner



RE: Solaris 10 kernel tuning

Presumably you need to do this as root?

Who *does* own PID 7953?

Yeah this was the mistake I was making, I was not root, D'oahsmile

SO the next step is to make it perm, any good pointers on doing this?



RE: Solaris 10 kernel tuning

I'm guessing, since I've never used projects, but you probably need to create a project and add the user(s) in question to that project, along with the default resource control settings for that project.  See man 4 project and man projadd for starters... or probably better head over to the Solaris documentation for an overview of projects in general?
