Tuning the Linux operating system
If Oracle SOA Suite 11g is installed on a Linux operating system, consider in-
creasing the ulimit for environments with large load. This is to avoid the following
error, which appears in the /var/log/messages log under heavy load:
Dec 25 20:53:22 soahost1 sshd[22480]: fatal: setresuid 10000: Resource temporarily unavailable
As the root user, perform the following:
1.
Add the following in /etc/security/limits.conf (assuming the product
is installed by the oracle Unix user):
oracle soft nproc 16384
oracle hard nproc 63536
oracle soft nofile 16384
oracle hard nofile 63536
2.
Add the following in /etc/profile (for 32-bit operating systems):
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
# Use the following for 64-bit operating systems instead
# ulimit -Su 16383
# ulimit -Hu 16383
# ulimit -Sn 63535
# ulimit -Hn 63535
else
ulimit -u 16384 -n 65536
# Use the following for 64-bit operating systems instead
# ulimit -Hn 63535 -Sn 63535 -Hu 16383 -Su 16383
