Installation guide
2.3.2. HP-UX System Configuration
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
TIME_WAIT value, and modify kernel parameters.
• Section 2.3.2.1, “Perl Prerequisites”
• Table 2.6, “HP-UX 11i Kernel Parameters”
• Section 2.3.2.3, “TIME_WAIT Setting”
• Section 2.3.2.4, “Large File Support”
• Section 2.3.2.5, “DNS Requirements”
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.
2.3.2.2. Kernel Parameters
The parameters to edit and the recommended values are listed in Table 2.6, “HP-UX 11i Kernel
Parameters”.
Parameter Setting
maxfiles 1024
nkthread 1328
max_thread_proc 512
maxuser 64
maxuprc 512
nproc 750

2.3.2.3. TIME_WAIT Setting
Normally, client applications that shut down correctly cause the socket to linger in a TIME_WAIT
state. Verify that the TIME_WAIT entry is set to a reasonable duration. For example:
ndd -set /dev/tcp tcp_time_wait_interval 60000
