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")
