How to resolve when the Oracle listener log is full?

When the Oracle listener log is full, it may impact the normal operation of the database. To resolve this issue, one can refer to the following steps:

1. Cleanup monitoring logs: To do this, log in to the Oracle database server and locate the path to the listener log file, which is usually in the ORACLE_HOME/network/log directory. You can free up space by either deleting old log files or emptying the log file.
2. Adjusting log file size: You can adjust the size of log files by modifying the configuration file listener.ora. You can increase the size limit of log files or regularly clean up historical log files to prevent them from getting too large.
3. Regularly monitor log files: it is recommended to regularly monitor the listener’s log files to promptly identify and address any issues with log files becoming too large.
4. Restarting the listener: If the above methods do not solve the problem, you can try restarting the listener service to regenerate the listener log files.

Here are some methods to solve the issue of Oracle listener logs being full. Choose the appropriate method based on the specific situation. If the problem persists, it is recommended to contact an Oracle database administrator or technical support for further investigation and resolution.
