Getting Started with Oracle database-directory structure

I.. ORACLE_HOME CATALOGUE

The Oracle_home home directory is located under the D:\dev\oracle\product\10.2.0 (Oracle installation path), which contains the subdirectories and network files associated with the Oracle software operation, as well as the selected components, etc. If the first and only Oracle database is installed on the host and there are no other Oracle products, the default home directory \db_1 is used, and if multiple products are installed or installed for the 2nd time in the same root directory of the same host, the Oracle_home home directory will appear as Db_n. namely db_2, Db_3 and so on. This is why the Oracle_base directory can have multiple oracle_home directories.

The main subdirectories included in the Oracle_home (D:\dev\oracle\product\10.2.0\db_1) directory are:

\bin--mainly includes various commands for database management.

\css--files related to Oracle Cluster Synchronization Services.

\dbs--holds the parameter file SPFile of the database server side.

\demo--the script that holds the database instance pattern.

The \install--is used to store the Oracle installed port number, Isql*plus, and how Enterprise Manager Database control starts and logs on.

\network\admin--about listeners Listener.ora and Sqlnet.ora as well as Tnsnames.ora and so on.

\sysman\config--is used for port management related to Oracle Enterprise management.

Second, the admin directory

The database management files are stored in the D:\DEV\ORACLE\PRODUCT\10.2.0\ADMIN\ORCL directory. The main meanings of each subdirectory are as follows:

\bdump--The background process trace file.

\cdump--Information dump file (core dump).

\create--the database to create the file.

\exp--the database export file.

\pfile--initializes the parameter file.

\udump--user SQL Trace file.

Iii. Catalogue of Oradata

The database files are stored in the D:\DEV\ORACLE\PRODUCT\10.2.0\ORADATA\ORCL directory, which primarily stores the database's control files, data files, and redo log files. Where the *.dbf file corresponds to each table space in the database; the. ctl file is the control file; the. log file corresponds to the Redo log file group and its members.

Iv. Catalogue of Flash_recovery_area

The Flash_recovery_area directory stores and manages files related to backup and recovery. It contains subdirectories for each database in the system. This directory can be used to store recovery-related files, such as control files, online redo log copies, archive logs, flashback logs, and Oracle Database Recovery Manager (RMAN) backups.
