Message: Hi Manju,

It means that TEST database service was updated successfully with the listener. There are two ways you let listener recognize your database. One by listing your database in SID_LIST_$LISTENER_NAME in the listener.ora file or secondly by let listener discover the database service (this usually takes some time may be couple of minutes ater the database has been started).

Message: Hi Manju,
Meaning of service_update is ...
The listener received updated registration information for a particular instance, such as dispatcher or instance load information.

Message: Hi Shailandra Vaish, Aditi Chatterji,
Thanks for the rapid reply; I have one more doubt to. When a client connect to DB how the service is updating because I didn’t make any changes in the listener setting but this message is keep on coming in the log file. Will it have any impact inf performance

As per my current set up client are using the oracle 6i to connect using Net 8.
Regards
Manju

Message: Hi,

caused by an LOCAL_LISTENER entry in your init.ora file PMON attempts every minute a registration of the instance to the listener defined, if you do not have a local_listener entry it looks for listener running on port 1521 (default port) to register.

If listener is up and you start your instance, registering will take place immediately, if instance is up and you start your listener, it can take up to one minute til it is registered.

You will not suffer from bad performance due to this service updates.

Here you'll get some more informations:
