Tuning the Linux operating system

If Oracle SOA Suite 11g is installed on a Linux operating system, consider increasing 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. 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. 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
    ulimit -u 16384 -n 65536
    # Use the following for 64-bit operating systems instead
    # ulimit -Hn...
