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.
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>
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 profileinit<DBSID>.sapis 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).
The environment variables SAPDATA<n> must only be defined if directories are used that differ from the default.
· TWO_TASK
Identification of a remote database system.
This environment variable must be left unset.
Other environment variables that you can set for BR*Tools:
· BR_LINES
Definition of the number of lines in list menus.
Recommended height: ³ 20 lines.
