Setting kernel values on Solaris systems

Some Solaris kernel values are typically too small for a WebSphere® ESB installation. Learn how to set selected kernel parameters to higher values.

About this task

Use the following procedure to set kernel parameters.
Procedure
  1. If you are not already logged into the host workstation as root, do so.
  2. Review the workstation configuration.
    Do this by entering the following command:
    sysdef -i
  3. Set the kernel values. The kernel parameters you must change and the way you do so differ depending on which version on Solaris you have installed.
    • If you have Solaris 9 installed, do the following:
      1. Edit the /etc/system file. Use the values shown in the following example:
        set shmsys:shminfo_shmmax = 4294967295
        set shmsys:shminfo_shmseg = 1024
        set shmsys:shminfo_shmmni = 1024
        set semsys:seminfo_semaem = 16384
        set semsys:seminfo_semmni = 1024
        set semsys:seminfo_semmap = 1026
        set semsys:seminfo_semmns = 16384
        set semsys:seminfo_semmsl = 100
        set semsys:seminfo_semopm = 100
        set semsys:seminfo_semmnu = 2048
        set semsys:seminfo_semume = 256
        set msgsys:msginfo_msgmap = 1026
        set msgsys:msginfo_msgmax = 65535
        set rlim_fd_cur = 1024
      2. Reboot the operating system.
    • If you have Solaris 10 installed, do the following:
      1. Alter the value of shmmax in the etc/project file by using the projmod command, as follows:
        # projmod -a -K "project.max-shm-memory=(priv,4G,deny)" default
      2. Reboot the operating system.
