How to delete the contents of the trace folder in the oracle database?

The trace folder in the Oracle database stores the log files and trace files of the database. In order to free up disk space and maintain the health of the database, it is necessary to delete some expired log and trace files. Here are the steps to delete the contents of the trace folder in the Oracle database:

1. Open the SQL*Plus or SQL Developer tool and log in to the target database as an administrator.

2. Check the trace folder location with the following command:

   show parameter background_dump_dest
   

   This command can display the path where the log files and trace files of the database are stored. Make a note of this path for later use.

3. Turn off the trace logging function of the database:

   alter system set trace_enabled=false;
   

   This command turns off the trace log and debug log functions.

4. Turn off event tracking for the database:

   alter system set events='';
   
   该命令会关闭与事件相关的跟踪功能。
   
   

5. Turn off the sql tracking function of the database:

   exec dbms_monitor.database_trace_disable;
   

   This command will turn off the functions related to sql statement tracing.

6. Use the file management tool of the operating system to delete the expired files in the storage path of the target database tracking files.

7. Restart the trace log function of the database:

   alter system set trace_enabled=true;
   

   This command restarts the trace logging and debug logging functionality.

8. Restart the event tracking function of the database:

   alter system set events=’10046 trace name context off';
   

   This command restarts event-related tracing.

9. Restart the sql trace function of the database:

   exec dbms_monitor.database_trace_enable;
   

   This command will restart the functions related to sql statement tracing.

10. Quit the SQL*Plus or SQL Developer tool.

When deleting the trace folder of the database, please be careful so as not to delete important files and data. We recommend backing up any files before deleting them.
