•Runthedsktune utility and see if you need to install any other patches. The
utility helps you to verify whether you have the appropriate patches installed
on your system and provides useful information and advice on how to tune
your kernel parameters for best performance. For information on running the
dsktune utility, see Chapter 8, “Troublesh ooting.”
Tuning the System
Set your kernel parameters as follows:
• Makesurethe
maxdsize kernel parameter is at least equal to:
cachesize * entrysize + 4096
Thatis, ifyour Directory Servercachesize is 1000 (this is the default) and your
average directory entry size is 20 KB, then make sure your maxdsize kernel
parameter is at least (1000*20000) + 4096, or at least 21 MB.
•Set
max_thread_proc (max number of threads per process) to 128.
•Set
ncallout (max number of pending timeouts) to 128+NPROC.
•Set
maxfiles to at least 120.
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
2. Create the large file system. For exam ple:
fsadm -F vxfs -o largefiles /dev/vg01/rexport
3. Rem ou nt 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.
