Would a Solaris kernel engineer please be so kind as to translate the following for me:

the following is just an example parameter, but my question concerns ALL OBSOLETED kernel parameters in Solaris 10 (conceptual question).

"msgsys:msginfo_msgmni (Solaris 9 Releases)
Obsolete in the Solaris 10 release."

Does this mean that

a) this kernel parameter no longer exists in /etc/system, but can still be tuned manually and will affect the performance of a Solaris 10 system


This is correct. They are now set using the resource control commands.

b) this kernel parameter no longer exists in /etc/system and cannot be tuned as such, but there are other parameters that are related to it and will still need to be considered

 
I think this was answered above.

c) this kernel parameter no longer exists and cannot be tuned manually in any way

 

Its still there but as  project.max-msg-ids now with a default value of 128. The old default value was 50.

c) this kernel parameter is now dynamically calculated / adjusted?


The parameter is now dynamically adjusted and there is no need for a reboot anymore. 

What does "obsolete" mean in this context?



Here is a link also that has some docs about this parameter and others that have been obsoleted from /etc/system but can still be set dynamically set via the resource controls.

If you need help setting the parameters let me know and I can help.
