How to locate the storage path of Oracle Ora files?

In the Oracle database, the ORA file is a log file used to record the operating status of the database instance. It is very important for database administrators to understand the storage path of the ORA file. Sometimes, we need to manually find the location of the ORA file in order to review certain error messages or troubleshoot. In this article, we will introduce how to find the storage path of the ORA file in the Oracle database, and provide some specific code examples to help everyone understand better.

First of all, it should be clear that there are many different types of ORA files, such as alert log files, trace files, archive log files, etc. Each type of ORA file has a different storage path, so we need to find their location separately.

1. Storage path of alert log file:
   Alert log files usually store the running status, warning information, error information, etc. of the database instance, which we often need to check when troubleshooting problems. document. In the Oracle database, the storage path of the warning log file can be queried through the following SQL statement:

SELECT value
FROM v$diag_info
WHERE name = 'Diag Alert';

The above SQL statement will return the storage path of the warning log file. Generally, you can see something like this in the returned results. The path of "/u01/app/oracle/diag/rdbms/orcl/orcl/trace".

2. Storage path of trace files:
   Trace files are usually used to record the running trajectory of database instances and are important information for debugging and troubleshooting when problems occur. If you want to find the storage path of the tracking file, you can query it through the following SQL statement:

SELECT value
FROM v$diag_info
WHERE name = 'Diag Trace';

The above SQL statement will return the storage path of the tracking file. Generally, you can see something similar to "/u01" in the returned result. /app/oracle/diag/rdbms/orcl/orcl/trace" path.

3. Storage path of archive log file:
   Archive log file records the history of database operations and is an essential file when restoring the database. To find the storage path of the archive log file, you can query it through the following SQL statement:

SELECT dest_name, destination, status
FROM v$archive_dest;

The above SQL statement will return the storage path information of the archive log file, including the archive destination name, storage path and archive status .

Through the above code examples, we can clearly understand how to find the storage paths of different types of ORA files. For Oracle database administrators, it is very helpful to be familiar with the storage location of ORA files, which can help them manage the database more efficiently and troubleshoot.
