Environment variables define values used by the Oracle database and BR*Tools. This section describes the variables used when the operating system is UNIX.

 

The database uses the environment values for many different purposes. BR*Tools also use the values.

Structure

The following variables are required:

  • ORACLE_SID

    System ID of the database instance

    Example: C11

    SAPSID or sapsid refers to the SAP System ID.

    DBSID or dbsid refers to the name of the database instance (database instance system ID).

    When a single instance is installed, SAPSID and DBSID are the same.

  • ORACLE_HOME

    Home directory of the Oracle software.

    Standard: /oracle/<DBSID>/<database version>

  • SAPDATA_HOME

    Directory of the database files.

    Standard: /oracle/<DBSID>

    Note Note

    The variables ORACLE_SID, ORACLE_HOME and SAPDATA_HOME must always be set. There is no default.

    End of the note.
