HP-UX Requirements and Tuning for 64-Bit SPD Server

System Requirements

  • Required OS level: HP-UX 11i 64-bit OS (HP-UX 11.11 for PA-RISC) or HP-IA64 64-bit OS (HP-UX 11i v2, HP-UX 11.23 for Itanium)
  • Minimum system configuration: HP-PA 2.0 server system with minimum 2 GB memory

Kernel Tuning Requirements

The following kernel parameters are for HP-UX 11.11 and HP-UX 11.23. You must adjust these parameters on the HP server system on which you will run SPD Server. After you make these changes, reboot the system before you attempt to use the SPD Server. In the following example, MAX(a,b) means to use the maximum of the values a or b.
dbc_max_pct = 10%
   dbc_min_pct = 2%
   max_thread_proc = 512
   maxdsiz_64 = 1Gb + MAX(SORTSIZE, INDEX_SORTSIZE)
   maxuprc = 4 + #concurrent SPD Server users
   nproc = current nproc value + 4 + #concurrent SPD Server users
SORTSIZE and INDEX_SORTSIZE are SPD Server parameters in the spdsserv.parm file. If you increase the values of these SPD Server parameters, you might also need to adjust the HP-UX kernel parameters. For more information about SPD Server parameters, see SPD Server UNIX Installation Guide .
Depending on the way that you use the SPD Server, you might also need to increase the value of the following HP-UX kernel parameters:
ninode=
maximum number of open inodes in memory. Change this value to the maximum number of SPD tables that will be open concurrently multiplied by the maximum number of partitions in an SPD Server table.
nfile=
maximum number of files that can be open system-wide. Change this value to the maximum number of SPD Server tables that will be open concurrently multiplied by the maximum number of partitions in an SPD Server table.
nflocks=
maximum number of files that can be locked system-wide. Change this value to the maximum number of SPD Server tables that will be open concurrently.
maxfiles_lim=
process hard limit for open files. Change this value to the maximum number of SPD Server tables that will be open concurrently multiplied by the maximum number of partitions in an SPD Server table. The minimum recommended setting is 8192.

Required Patches
