Hello All:
I am trying to tune SF15K for performance related work. The application
involves Oracle database on one of the domains and WebSphere application
on another domain.
Oracle DB domain:
16 x 900 Mhz processors, 32 GB memory , Solaris 8, 100 Mbps Full duplex
Ethernet
WebSphere Domain:
12 x 900 MHz processors, 24 GB memory Solaris 8, 100 Mbps full-duplex
ethernet.
Are there any specific tunings that are related to 15K that I might have
missed. I have done many of Oracle SGA related tunings and Solaris kernel
tunings.
Here is /etc/system from oracle domain:
************************************

set msgsys:msginfo_msgmnb = 65535
set msgsys:msginfo_msgmni = 7168

set semsys:seminfo_semmni = 8192

set ce:ce_adv_100hdx_cap=0
set ce:ce_adv_10fdx_cap=0
set ce:ce_adv_10hdx_cap=0
* End ethernet adapter setting
**************************************************
What I am looking for, from all of you experts is:
1. Anything obvious that I might have missed
2. Any pointers to some books/URLs,
Any tuning help/pointers will be highly appreciated. I will summarize.
