Troubleshooting
This chapter describes the most common installation problems and how to solve them. It also provides
some tips on checking patch levels and kernel parameter settings for your system.
This chapter has the following sections:
• Section 7.1 Running dsktune
• Section 7.2 Common Installation Problems
7.1. Running dsktune
The dsktune utility provides an easy and reliable way of checking the patch levels and kernel param-
eter settings for your system. You must install the Directory Server before you can run dsktune.
On Solaris platforms, if you run the dsktune utility, it reports as missing any of the patches from the
Sun recommended patch list that are not installed on your system, even if they relate to packages that
you have not installed.
To run dsktune:
1. Change to the installation directory for your Directory Server.
By default, this directory is /opt/redhat-ds/servers.
2. Change to the bin/slapd/server subdirectory.
3. As root, enter the following command:
./dsktune
The following is an example of output that dsktune generates. dsktune does not itself make any
changes to the system.

NOTICE : System is hppa2.0/549-hp9000/785/J5000-hpux_B.11.11.
WARNING : Only the superuser can check which patches are installed.
You must run
dsktune as root to ensure the necessary patches are present.
If required patches
are not present, the server may not function correctly.
NOTICE : The tcp_keepalive_interval is set to 7200000 milliseconds
(120 minutes).
This may cause temporary server congestion from lost client
connections.
An entry similar to the following should be added to
