    Example settings for kernel parameters
    Following is an example of tuning the kernel parameters for NetBackup master
    servers and media servers, for Solaris 8 or 9.

    The following values are the recommended minimums. If /etc/system already
    contains any of these entries, use the larger of the existing setting and the
    setting that are provided here. Before modifying /etc/system, use the
    command /usr/sbin/sysdef -i to view the current kernel parameters.

    After you have changed the settings in /etc/system, restart the system to
    allow the changed settings to take effect. After the restart, the sysdef
    command displays the new settings.

    wrobbins solution is valid even though its title is for 6.x it is still applicable to your environment.
