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.

Executing /tmp/redhat/dsktune...

Red Hat Directory Server system tuning analysis version

04-APRIL-2005.

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

/etc/rc.config.d/nddconf:
