Bookshelf v7.5: Managing Environment Variables

There are several environment variables that must be properly set for successful and optimal functioning of the Siebel Server. These include:

Table 14 provides instructions for setting and managing these environment variables. For detailed information on tuning the UNIX kernel and other tunable parameters for Siebel Server optimization, see Tuning UNIX Operating Systems for Siebel Installation.

Table 14. 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 Siebel `siebenv.sh` and `siebenv.csh` environment variable files, which are created during server installation. Always points to `$SIEBEL_ROOT/sys/.odbc.ini.`	N/A (Not to be modified.)
`SIEBEL_UNIXUNICODE_DB`	This controls the ODBC driver manager responsible for connection to the RDBMS. Reset, if necessary, within the `siebenv.*` file before sourcing it.	Default is `DB2`. You must reset to `ORACLE` if your database is Oracle
`LANG`	Language environment variable within the `siebenv.csh` or `siebenv.sh` file. Sets Siebel Database Server client environment appropriate to language of installation.	Set this to the language in which your database runs

The Siebel environment variables $SIEBEL_GATEWAY and $SIEBEL_ROOT must be set when you are executing the Siebel installation and configuration scripts. These environment variables must also be set to enable execution of the Siebel Gateway and Siebel Server management utilities, documented in Siebel Server Administration Guide.

During the Siebel Gateway installation process, 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.
