By default, ssctuner is installed and running. If for some reason ssctuner is not installed, use this procedure to install it.
Use the Oracle Solaris package command and package name based on the version of the OS.
Oracle Solaris 10 OS:
# pkgadd -d ORCLssctuner
Oracle Solaris 11 OS:
# pkg install ssctuner
Oracle Solaris 10 OS:
# pkginfo ORCLssctuner
Oracle Solaris 11 OS:
# pkg info ssctuner
# svcs ssctuner
If the service does not transition to an online state after a minute or two, check the service log file. See View Log Files.
When ssctuner changes configuration files, you must reboot the OS for those changes to take effect.
