Dears,

I have a Solaris System, E10K with 8 CPU of 400 MHZ 6 GB of RAM
and Oracle 7.34, 3 instances and a messagging local packages running.

I detected a Mutex contention, because the CPU (sys) > 20% and > CPU (usr)
besides mpstat (smtx) > 500. sometime CPU (sys)>60 % idle (0%)

How can I fix that problems or detect the fail ?
Is there some scheme or procedure that permit me to localize the problems.
troubleshooting scheme ?

I tried lockstat but the result sometime confused me ?

Please give me some Hints or documents that permit me to clarify the problems

waiting for some hints, recomendation, etc.

Regards,

Josh Mhndez

I 'm attaching some information.

the documentation refer the bold hexadecimal number as a hashed locks
how can associate that with something coherent ?
