SYNOPSISDESCRIPTION
The tool tunes the kernel tunables to improve server performance.
There are certain kernel tunables identified, which when updated with
the appropriate values, improves the performance of servers signifi‐
cantly.
For complete details about these tunables and their values, refer to
the whitepaper at
Options
Provide usage information of the tool.
List all tunables and their optimal values.
Optimizes the value of kernel tunables so that performance will be
improved.
Sets the value of kernel tunables back to the value
prior to the optimization that was done with the option. This
option is provided so that tunables can be set to their original
values, if required.
For both and options, the server need to be restarted for the tunable
changes to be applied to the system. This tool gives a message if
restart is required.
RETURN VALUE
The tool returns zero upon successful completion, or nonzero if it
fails.
