Environment Variables (UNIX)Locate this document in the navigation structure

Definition

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

Use

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

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

The following environment variables must only be set if the corresponding paths deviate from the defaults specified here:

  • SAPARCH

    Directory for the BRARCHIVE logs.

    Default value: $SAPDATA_HOME/saparch

  • SAPBACKUP

    Directory for the BRBACKUP, BRRESTORE, and BRRECOVER logs.

    Default value: $SAPDATA_HOME/sapbackup

  • SAPCHECK

    Directory for the BRCONNECT logs.

    Default value: $SAPDATA_HOME/sapcheck

  • SAPREORG

    Directory for the BRSPACE logs. It is also the standard directory for export dump files, if the parameter exp_dump_dir in the profile init<DBSID>.sap is not set.

    Default value: $SAPDATA_HOME/sapreorg

    Directory for Oracle trace files and the alert file.

    Default value: $SAPDATA_HOME/saptrace

  • SAPDATA1

    Directory of the database data files.

    Default value: $SAPDATA_HOME/sapdata1
