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

Definition

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

Use

The database uses the parameter values for many different purposes. BR*Tools also uses the parameter 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: <drive>:\oracle\<DBSID>\<database version>

    Example: D:\oracle\C11\112

  • SAPDATA_HOME

    Directory of the database files.

    Standard: <drive>:\oracle\<DBSID>

    Example: E:\oracle\C11

    Note

    The variables ORACLE_SID 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 logs from BRBACKUP, BRRESTORE, and BRRECOVER.

    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

  • SAPTRACE

    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

    (The same for SAPDATA<n>, n=1,...99).

    Note

    You can distribute the SAPDATA directories across several different drives, without defining the environment variables SAPDATA<n>. The environment variables only have to be defined individually if directory names are used that deviate from the default.

    For example: SAPDATA1= F:\data\prod\sapdata1.

Other environment variables that you can set for BR*Tools:

  • BR_LINES

    Definition of the number of lines in list menus.

    Recommended height: greater than or equal to 20 lines.

    For more information, see Configuring the Scroll Line Count for BR*Tools.

  • BR_LANG

    Definition of the message language:

    • E: English

    • D: German

  • BR_TRACE

    Setting the trace function for error analysis. For more information, see SAP Note 29321.
