bundle the HTML files for delivery to the hpssgui host machine. The recommended installation
location for the HTML files on each hpssgui host is /var/hpss/doc for AIX and Linux platforms and
c:\hpss\doc for Windows platforms.
5.5.2. Manual Page Setup
Perform the following steps to set up HPSS manual pages:
1. Create a symbolic link for the HPSS manual catalog. Assuming that the HPSS tree is
installed at /opt/hpss, use the following commands:
% su - root
% cd /opt/hpss
% ln -s man cat7
2. Edit the /etc/environment file so that users will have the HPSS manual pages in their
MANPATH. Assuming that the HPSS tree is installed at /opt/hpss, add the following line to
the end of the /etc/environment file:
MANPATH=${MANPATH}:/opt/hpss
After this is done, users who subsequently login to the system will be able to view HPSS manual
pages using the man command. For example, to view the lshpss manual page:
% man lshpss
5.6. Define HPSS Environment Variables
While most, if not all HPSS environment variables can be used as defined by HPSS, they should be
reviewed to ensure that they are set to reflect your environment. The HPSS environment variables
and their default values are defined in /opt/hpss/include/hpss_env_defs.h file. See Appendix E:
hpss_env_defs.h which lists the default values of all HPSS environment variables. These environment
variables may be overridden in /var/hpss/etc/env.conf or in the system /etc/environment file
The /opt/hpss/config/hpss_set_env utility can be used to insert environment variables into the /var/
hpss/etc/env.conf file, list the values of the current HPSS environment variables, or list all HPSS
default environment values:
Usage:
hpss_set_env [-all] [-def] [-set ENVNAME=NEWVALUE] |
ENVNAME [ENVNAME...]]
Where:
-all Show current HPSS environment values
-def Show all HPSS default environment values
-set Set HPSS default environment values
ENVNAME Display current value for ENVNAME
5.7. Tune DB2
Database tuning is an important aspect of maximizing HPSS performance, but it is a complex topic,
requiring study and experimentation, to do well. mkhpss creates initial configuration parameters for
HPSS DB2 instances that we find to be effective for most systems, but additional tuning to deal with
the specifics of a given HPSS installation may improve database performance. Administrators
