Hey,

at first try Sun BluePrints Program and click archives
by date. Search with your browser "tuning", you find some
interesting blue prints.
Second - at docs.sun.com you will find the complete documentation
for tuning solaris.

bye

Thanks. Smilie

But where I can tune IPC tunable parameters and how ? for eg.

Resource Obsolete Old Default Maximum New Default
Control Tunable Value Value Value

process.max- msginfo_msgmnb 4096 ULONG_MAX 65536
msg-qbytes

process.max- msginfo_msgtql 40 UINT_MAX 8192
msg-messages

process.max-sem seminfo_semopm 10 INT_MAX 512
-ops


How can i tune parameters like default_stksize, fsflush, ufs_ninode, maxphys etc.

Thanks
