I was looking at our listener.log and noticed the folowing :
02-MAY-2001 19:03:20 * service_update * amlp * 0
repeated many times.
Does anyone know what this means, what the system was doing at the time these messages appeared ?
Thanks in advance
The database updates the Listener every 10 minutes apart from registering/unregistering during startup/shutdown. This is normal. This frequency cannot be changed or configured.

The message you are getting has to do with the listener - service_update is logged when there is a change.
In MTS environment, the database updates the listener with dispatcher and server information as there are dynamic in nature. The Listener needs to know whenever the dispatchers/servers change in number.
