CASE When Passing 6600 Transactions spread across 250 Concurrent users on SUN APP Server
as part of Benchmarking Exercise

Hardware - Sun APP Server 4 CPU , 4 GB RAM , 3.5 GB Swap

Software - Solaris 2.6 on Oracle 7.3.4.5

Application - Pro*c Application with Embedded SQLs in a Banking Product

ERROR :- Error Message : [System call failed Error Num [12], Error [Not enough space] Error : the requested size of memory for allocation was:[131072]

NOTE -
Minimum FREE Memory measured During the Duration of the Transactions Run
(thru vmstat) = 2 GB

Swap = 3.5 GB

/etc/system :-

set shmsys:shminfo_shmseg=200
set shmsys:shminfo_shmmin=2
set shmsys:shminfo_shmmni=200

forceload: sys/shmsys
forceload: sys/semsys

set semsys:seminfo_semaem=16384
set semsys:seminfo_semmap=1000
set semsys:seminfo_semmni=1000
set semsys:seminfo_semmns=6000
set semsys:seminfo_semmnu=1000
set semsys:seminfo_semume=200
set semsys:seminfo_semvmx=32767
set shmsys:shminfo_shmmax=3221225472

set c2audit:audit_load = 1
set abort_enable = 0
*----Added to increase the pttys
set pt_cnt=512
*---Added to increase the no of process per user set maxuprc=1024
set maxusers=512
set nproc=6000
*---Added to increase no of open file fd's per process set rlim_fd_max=1024
set rlim_fd_cur=1024

Any Advice for any Suitable Setting in /etc/system or ... ?
