Managing Environment Variables

There are several environment variables that must be properly set for optimal functioning of the Siebel Server, as shown in Table 15. These include:

• Siebel environment variables
• UNIX operating system environment variables

NOTE:  For information on tuning the UNIX kernel and other parameters for Siebel Server optimization, see Siebel Performance Tuning Guide.

The Siebel environment variables $SIEBEL_HOME and $SIEBEL_ROOT must be set to enable execution of the Siebel Gateway Name Server and Siebel Server management utilities documented in Siebel System Administration Guide.

During Siebel Gateway Name Server and Siebel Server installation and configuration, the script files siebenv.csh (for the C shell and its variants) and siebenv.sh (for the Bourne and Korn shells and their variants) are automatically created in the $SIEBEL_ROOT directory. When sourced, these shell scripts set the environment variables.

If you have configured your Siebel Server to start manually, you must source siebenv.* before starting the server. For this reason, you may want to add a call to the appropriate siebenv.* script to the logon files of all Siebel administrator UNIX accounts, so that these variables are set automatically whenever a Siebel administrator logs on.

NOTE:  If you want to change the default settings of these environment variables, you must do so before you start the Siebel Server.

UNIX Tuning for Siebel Applications

There are several UNIX system environment variables you must set for proper functioning of the Siebel Server.

For detailed information on tuning the UNIX kernel and other tunable parameters for Siebel Server optimization, see Siebel Performance Tuning Guide.
