Kernel prerequisites for Messaging on Solaris 10

Problem

-- What are the latest Messaging kernel prerequisite
-- IPC parameters on Solaris10

Resolution

On Solaris 10, IPC parameters are now obsolete and are replaced by Solaris IPC resource control. Hence, the existing prerequisites mentioned in the Installation guide can be understood as below.

For Solaris 10, you should use the new, correspondent parameters. The values should be the same as the ones recommended for the obsolete parameters.Please see also http://docs.oracle.com/cd/E26505_01/html/E37386/chapter1-32.html

Also, if there is a default value greater than the recommended one, the default value should be kept. If a correspondence does not exists, the recommendation should be ignored.

Example

New Recommendations

msgsys:msginfo_msgmni

Resource Control = project.max-msg-ids
New Default = 128
Recommended = 1024

msgsys:msginfo_msgmnb

Resource Control = process.max-msg-qbytes
New Default = 65536
Recommended = 65536

msgsys:msginfo_msgmax

Removed in Solaris 10. Hence, can be ignored.
