Environment variables are no longer kept in the $HPSS_ROOT/config subdirectory. Many are now
kept in /var/hpss/etc/env.conf. The mkhpss utility will assist in creating the env.conf file and HPSS
specific environment variables can be added to it.
Before running the conversion utilities, ensure the following environment variables are properly
defined. These environment variables can be defined in the new env.conf file or any other way a site
defines environment variables. Ensure the HPSS server principal names below are set to proper
HPSS 6.2 values to match the restrictions of the chosen authentication and authorization mechanism.
For instance, if Unix authentication or authorization is chosen, each principal should be no longer
than 8 characters. The conversion uses these values to determine how to properly convert the system:
• DB2INSTANCE – the Unix User ID of the DB2 HPSS instance (e.g. "hpssdb"). The rc.db2
script sets this environment variable
• HPSS_GLOBAL_DB_NAME – the database name for the HPSS global configuration
database (e.g. "cfg"). Defined in /var/hpss/etc/env.conf. Used to recommend default values
for the current DB2 configuration
• HPSS_MM_SCHEMA_NAME – the schema for HPSS (e.g. "hpss"). Defined in
/var/hpss/etc/env.conf. Used to recommend default values for the current DB2 configuration
• HPSS_SEC_REALM_NAME – the Kerberos realm name to use (e.g. "hpss.acme.com").
Defined in the /var/hpss/etc/env.conf file
• DB_USER – set to HPSS DB2 instance owner user name (e.g. "hpssdb")
• DB_PASSWORD – set to DB_USER’s password
• HPSS_ROOT – set to root directory of HPSS 6.2 code (e.g. "/opt/hpss"). The rc.db2 script
sets this environment variable
• HPSS_SERVER_DB_GROUP – set to the new group name for HPSS servers (e.g. "hpsssvr")
• JAVA_ROOT – set to the path to Java 1.4, platform specific (e.g. "/usr/java14")
