Where is the Oracle Ora file storage path?

The Ora file in the Oracle database is a file used to store the relevant configuration information and parameter settings of the database instance. There are many different Ora files in the Oracle database. The specific storage path will be based on It varies between operating systems and Oracle versions. The following are several common Ora files and the paths where they are stored, as well as sample code on how to find them.

1. SPFILE: SPFILE is the parameter file of the Oracle database instance, which stores the dynamic parameter settings of the database instance. Under the Windows operating system, SPFILE files are usually stored in the $ORACLE_HOME/database directory, and the file name is spfile .ora. Under the Linux/Unix operating system, SPFILE files are usually stored in the $ORACLE_HOME/dbs directory, and the file name is spfile .ora.

The sample code to find the SPFILE file is as follows:

SQL> SHOW PARAMETER spfile;

2. PFILE: PFILE is the parameter file of the Oracle database instance, which stores the static parameter settings of the database instance. Under the Windows operating system, PFILE files are usually stored in the $ORACLE_HOME/database directory, and the file name is init .ora. Under the Linux/Unix operating system, the PFILE file is usually stored in the $ORACLE_HOME/dbs directory, and the file name is init .ora.

The sample code to find the PFILE file is as follows:

SQL> SHOW PARAMETER pfile;

3. TNSNAMES.ORA: The TNSNAMES.ORA file is the connection file of the Oracle database instance and stores the connection information of the database instance. . Under Windows operating systems, the TNSNAMES.ORA file is usually stored in the $ORACLE_HOME/network/admin directory. Under Linux/Unix operating systems, the TNSNAMES.ORA file is usually stored in the $ORACLE_HOME/network/admin directory.

The sample code to find the TNSNAMES.ORA file is as follows:

SQL> SELECT NAME, VALUE FROM V$PARAMETER WHERE NAME = 'tnsnames.ora';

In summary, the storage path and file name of the Ora file in the Oracle database will vary according to different operating systems and Oracle It varies depending on the version. By using the corresponding SQL query statements, these important Ora files can be easily found for corresponding configuration and management work.
