This article will explain in detail how to clean up and shut down listener log. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have some understanding of the relevant knowledge after reading this article.

By default, listener turns on log. In previous versions, if listener.log was greater than 2GB, it might cause listener to fail to respond to new connection requests.

Today, some netizens in the QQ group simply found that the space was not released through m listener.log, and finally solved it by restarting monitoring and instances (RAC environment). In fact, this is totally unnecessary.

So how should we properly clean up the listener log?

There are 2 ways:

1: violence point, direct cat / dev/null > listener.log

2: general approach: remove the listener.log by briefly closing the log of listener, and then turn on log.

LSNRCTL > help set

The following operations are available after set

An asterisk (*) denotes a modifier or extended command:

Password rawmode

Displaymode trc_file

Trc_directory trc_level

Log_file log_directory

Log_status current_listener

Inbound_connect_timeout startup_waittime

Save_config_on_stop dynamic_registration

Enable_global_dynamic_endpoint connection_rate_limit

LSNRCTL > set log_status off

Connecting to (DESCRIPTION= (ADDRESS= (PROTOCOL=TCP) (HOST=x.y.z.q) (PORT=1521)

LISTENER parameter "log_status" set to OFF

The command completed successfully

$> cd $LOGDIR

$> mv listener.log / / listener.log.bak

LSNRCTL > set log_status on

In fact, if you do not care the connection, you can turn off listner log.

It can be done in two ways:

1:LSNRCTL > set log_status off

2: modify listener.log directly, add LOGGING_LISTENER = OFF, and then execute lsnrctl reload or simply restart listener.

On how to clean up and close the listener log to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
