Just a question for now, in re: "....into an existing RAC cluster." What is
in your existing cluster?

Subject: Tuning for t-series nodes running Oracle DB
I'll soon be rolling new T4 servers running Solaris 10 08/11 (11.2.0.3 GI,
11.2.0.2 DB) into an existing RAC cluster. I'm beginning the process of
testing/tuning the new nodes before rolling them into production, but am
trying to find the best starting point for that effort.
What non-default kernel parameters beyond what is in the install docs are
people using to improve performance? How about db parameter values (i.e.
CPU_COUNT, etc)? BTW, I've read the MOS docs. They're mildly helpful and
also sometimes conflicting...
Has anybody experimented with using the new(ish) version of mtmalloc that
came with Solaris 10 08/11 on their db servers? If so, what were the
results from that change?
Any responses are appreciated.
Thanks,
Aaron
