HP-UX System Parameters
HP recommends that you verify and configure the following system settings to optimize Directory
Server Performance:
• “Kernel Parameters” (page 21)
— max_thread_proc
— maxfiles
— maxfiles_lim
— nproc
— maxdsiz or maxdsiz_64bit
• “TCP TIME_WAIT Interval” (page 22)
• “Large File Support” (page 22)
Kernel Parameters
HP Recommends that you set the following kernel parameters with the system default values:
max_thread_proc
256 (default)
maxfiles
2048 (default)
maxfiles_lim
4096 (default)
nproc
4200 (default)
To verify the current values of these kernel parameters, use the sysdef(1M) or kctune utility. For
example:
kctune | grep -e max_thread_proc -e maxfiles -e maxfiles_lim \
-e nproc
You can expect the following output after reconfiguration:
max_thread_proc
256
maxfiles
2048
maxfiles_lim
4096
nproc 4200
Maximum Data Segment Size (maxdsiz_64bit, maxdsiz_64bit) Recommendations
HP recommends that you set the maximum data segment size for a user process (maxdsiz on
32-bit systems or maxdsiz_64bit on 64-bit systems) to accommodate sizes of the Directory
Server caches. HP recommends that you set the maximum data segment size to at least the size
of (nsslapd-cachememsize) + ( nsslapd-dbcachesize).
The default values for these parameters are as follows:
• nsslapd-cachememsize: 10,485,760 bytes (approximately 10 MB)
• nsslapd-dbcachesize: 10,000,000 bytes (approximately 10 MB)
