Operating System Requirements

40 Netscape Directory Server Installation Guide • December 2003

•Set max_thread_proc to 512 (the old value was 64).

•Set

maxusers to 64 (the old value was 32).

•Set

maxuprc to 512 (the old value was 75).

•Set

nproc to 750, a new value which is not based on a formula (the old

formula was

20+8*MAXUSERS, which evaluated to 276).

Typically, client applications that do not properly shut down the socket cause it

to linger in a

TIME_WAIT state. To prevent this, you should consider changing

the

TIME_WAIT setting to a reasonable value. For example, setting

ndd -set /dev/tcp tcp_time_wait_interval 60000

will limit the TIME_WAIT state of sockets to 60 seconds.

You also need to turn on large file support in order for Directory Server to work

properly. To change an existing file system (from one that has no large files to

one that accepts large files):

1. Unmount the system using the umount command. For example:

umount /export

Create the large file system. For example:

fsadm -F vxfs -o largefiles /dev/vg01/rexport

Remount the file system. For example:

/usr/sbin/mount -F vxfs -o largefiles /dev/vg01/export

For additional information and recommendations about setting these

parameters, consult your operating-system documentation.

Installing Third-Party Utilities

You will need the gunzip utility to unpack the Directory Server software. The

GNU

gzip and gunzip programs are described in more detail at

http://www.gnu.org/software/gzip/gzip.html and can be obtained from

many software distribution sites.

You may need Adobe Acrobat Reader to read the documentation. If you do not

have it installed, you can download it from:
