Sometimes it is necessary to define system environment variables before you start SAS Stored Process Servers on UNIX platforms so that the connections to an external database management system (DBMS) in a stored process program will function properly.

Because the environment variables that are required and the values that are specified might vary at each site, you should contact your DBMS administrator for site-specific information.

To set system environment variables globally for all SAS sessions, add the necessary environment variables to the file !SASROOT/bin/sasenv_local.

To set system environment variables for all SAS compute-tier application servers, add the necessary environment variables to the SAS-configuration-directory/Lev1/level_env_usermods.sh script.

To set system environment variables only for the SAS Stored Process Server, add the necessary environment variables to the SAS-configuration-directory/Lev1/SASApp/StoredProcessServer/StoredProcessServer_usermods.sh script.

Shell-specific methods for setting system environment variables for your SAS installation are described in the Defining Environment Variables section of SAS^® 9.4 Companion for UNIX Environments, Sixth Edition.
