Hi,

We have tried a test on solaris 10 with RAC database 10GR2.But I am confusing with local and remote listener.And I have some research on the literature but i didn't find any information.

So could you please help me about understanding and explain remote listener.

Regards.

remote_listener is configured in the parameter file to specify
a name which resolves to listeners running on other nodes.
PMON thus registers with all the available listeners.

on also needs to include the address details of listener on one node inside the tnsnames.ora of other server.

This is basically a server side load balancing concept.

When clients attempt to connect they check then node/instance first connected to and the load is checked.

It checks basically this load via CPU and the listener registration. As mentioned earlier PMON registers with all the available listeners.

If its loaded it guides it to the remote node and this is via the remote_listener.


Corrections welcome.
