Oracle Database Directory Structure (UNIX)

This section describes the directory structure for the Oracle database with the Windows operating system.

The directories contain a range of files such as profiles, log files, scripts, executables, and so on.

The following conventions apply to this section:

Term	Meaning
%<name>%	Environment variable
<DBSID>	%$ORACLE_DBSID%
<TSP>	Tablespace short name For example, BTABD for the tablespace PSAPBTABD.

Structure

There are the following main structures:

·        %ORACLE_HOME% for Oracle-specific objects with the default directory :\oracle\<DBSID>

·        %SAPDATA_HOME% for SAP-specific objects with the default directory :\oracle\<DBSID>

·        Executables with the directory x:\usr\sap\<DBSID>\SYS\exe\run

Oracle Home Directory

This directory contains the following subdirectories:

·        database\

¡        spfile<DBISD>.ora Oracle spfile

¡        init<DBSID>.ora Profile for Oracle

¡        init<DBSID>.sap Profile for BR*Tools

¡        cntrl<DBSID>.dbf Control file

·        bin\

Contains binaries such as sqlplus, exp, imp, and so on

SAP Home Directory

For the files starting log_, gmeans group and m means member:

·        origlogA\

¡        log_tg101m1.dbf

¡        log_tg103m1.dbf

·        origlogB\

¡        log_tg102m1.dbf

¡        log_tg104m1.dbf

Mirrored redo logs are optional – although we strongly recommend using them – so the specification for mirrlogA and mirrlogB might vary:

·        mirrlogA\

¡        log_tg101m2.dbf

¡        log_tg103m2.dbf

·        mirrlogB\

¡        log_tg102m2.dbf

¡        log_tg104m2.dbf

·        sapdata1\

¡        cntrl\cntrl<DBSID>.dbf Control file

¡        system_1\system.data1 SYSTEM tablespace file

¡        btabd_1\btabd.data1 Example of a SAP data file for tablespace PSAPBTABD

¡        ...

·        sapdata2\

¡        cntrl\cntrl<DBSID>.dbf Control file
