dsktune Utility
For UNIX platforms, Directory Server provides a utility named dsktune that
can help you verify whether you have the appropriate patches installed on your
system. The utility also provides useful information and advice on how to tune
your kernel parameters for best performance.
To enable you to run
dsktune before installing the Directory Server, the utility is
placed, along with the
setup program, in the directory where you unpack product
binaries. Additionally, in the 6.2 release, the
setup program has been enhanced to
allow specifying of a pre-pre-installation program to be run before the Directory
Server installation begins—in the
slapd.inf file, a new field named
PrePreInstall is defined for specifying the path to the executable, which must be
relative to the
setup program. By default, the PrePreInstall field is set to the
dsktune utility path, enabling you to run the utility as a part of the Directory
Server installation.
After you’ve installed the Directory Server, you can find the utility in this
directory:
serverRoot/bin/slapd/server
For information on running dsktune, see Chapter 8, “Troubleshooting.”
