7. Troubleshooting
7.1. Running dsktune
dsktune runs when the Directory Server is first set up to check for minimum operating
requirements. After the setup, the dsktune utility can determine the Directory Server patch
levels and kernel parameter settings. To launch dsktune, Directory Server has to be installed
successfully first.
NOTE
You must run dsktune as root.
On Solaris, dsktune automatically checks the patches and compares them with the current Sun
recommended patch lists. If it detects that the system is missing an important patch, dsktune
will notify you, even if the patch is for package that is not installed yet.
The command to run dsktune is as follows:
/usr/bin/dsktune
The dsktune utility then scans the system for required patches and dependencies.
