2.2.3.2. HP-UX System Configurat ion
Before setting up Directory Server, tune your HP-UX system so Directory Server can access the
respective kernel parameters. To tune HP-UX systems, enable large file support, set the T IME_WAIT
value, and modify kernel parameters.
Section 2.2.3.2.1, “Perl Prerequisites”
Table 2.6, “HP-UX 11i Kernel Parameters”
Section 2.2.3.2.3, “T IME_WAIT Setting”
Section 2.2.3.2.4, “Large File Support”
Section 2.2.3.2.5, “DNS Requirements”
2.2.3.2.1. Perl Prerequisites
On HP-UX, Red Hat Directory Server uses the Perl version installed with the operating system in
/opt/perl_64/bin/perl. Contact Hewlett-Packard support if this Perl version is not installed.
2.2.3.2.2. Kernel Parameters
The parameters to edit and the recommended values are listed in T able 2.6, “HP-UX 11i Kernel
Parameters”.
Table 2.6. HP-UX 11i Kernel Parameters
Parameter Sett ing
maxfiles 1024
nkthread 1328
max_thread_proc 512
maxuser 64
maxuprc 512
nproc 750
2.2.3.2.3. T IME_WAIT Setting
Normally, client applications that shut down correctly cause the socket to linger in a T IME_WAIT state.
Verify that the T IME_WAIT entry is set to a reasonable duration. For example:
ndd -set /dev/tcp tcp_time_wait_interval 60000
This limits the socket T IME_WAIT state to 60 seconds.
2.2.3.2.4 . Large File Support
To run Directory Server on HP-UX, you must enable large file support.
1. Unmount the filesystem using the um ount command.
umount /export
2. Create the large filesystem.
fsadm -F vxfs -o largefiles /dev/vg01/rexport
