Managing Environment Variables

There are several environment variables that must be properly set for optimal functioning of the Siebel Server, as shown in Table 10. These include:

  • Siebel environment variables
  • UNIX operating system environment variables

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

Table 10. Setting and Managing Environment Variables
Environment Variable
Purpose
Recommended Siebel Value

ODBCINI

Tells the ODBC driver manager which file to open to look for the ODBC data source and driver information. Set within the environment setup files, siebenv.csh (for C shell) and siebenv.sh (for Bourne or Korn shell), which are created during Siebel Enterprise Server and Siebel Server configuration. This variable always points to $SIEBEL_HOME/sys/.odbc.ini.

Do not modify.

SIEBEL_UNIXUNICODE_DB

Controls the ODBC driver manager responsible for connection to the RDBMS. Reset, if necessary, within each environment setup file before sourcing it.

Set to ORACLE or DB2. This value is set automatically.

LANG

Language environment variable within the environment setup file. Sets the database server client environment appropriate to the language of installation.

For more information about specifying locales, see Specifying the Locale for Siebel Business Applications and Specifying the Locale for Your UNIX Operating System.

Set this to the language in which your database runs.

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 Enterprise Server and Siebel Server configuration, the script files siebenv.csh (for C shell) and siebenv.sh (for Bourne or Korn shell) 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, then you must source either siebenv.csh or siebenv.sh before starting the server. For this reason, you might want to add a call to the appropriate siebenv.* file to the logon files of all of the 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, then you must do so before you start the Siebel Server.

Tuning UNIX Operating Systems for Siebel Business Applications

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

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