ssctuner Overview
The ssctuner utility is a small set of Perl and Korn shell scripts and configuration files that run
on SuperCluster Oracle Solaris 10 and Oracle Solaris 11 global zones. By default, ssctuner is
installed and enabled at installation time.
The utility runs in realtime as an SMF service to monitor and tune ndd parameters and various
system configuration parameters including these files:
■
/etc/system
■
/kernel/drv/sd.conf
■
/kernel/drv/ssd.conf
■
/etc/inet/ntp.conf
The utility also periodically checks for the use of DISM or suboptimal NFS mount options.
By default, the utility runs every two hours and modifies parameters as needed.
