Installation guide

After the setup, the dsktune utility can determine the Directory Server patch levels and kernel
parameter settings. T o 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.

7.7.2. Common Installation Problems
There are several common problems that can come up during the setup process, generally relating to
network or naming problems. T hese problems and workarounds and soluions are described below.
For system information, try running the dsktune utility to identify potential hardware problems.
7.7.2.1. Problem: Clients cannot locate the server
Solution.
First, modify the hostname. If that does not work, use the fully-qualified domain name, like
www.dom ain.com , and make sure the server is listed in the DNS. If that does not work, check the IP
address.
If the NIS domain is not the same as your DNS domain, check your fully-qualified host and domain name.
