Hi,

How to stop all user connections to database from application ? Should i have to stop listener in all nodes ?

when i give ps -ef|grep tns , i get output as below

LISTENER
LISTENER_SCAN1
LISTENER_SCAN2

means there are 3 listener configured for all 3 nodes.

Its a RAC database with 3 node cluster.

Thanks,

Stopping the scan listeners

srvctl status scan_listener
srvctl stop scan_listener

will not have any effect on existing sessions, but you won't get any new sessions.
You might want to stop the service instead, you can use -force to break existing sessions.

Thank you John.

Quote:

srvctl status scan_listener
srvctl stop scan_listener

Should i run this srvctl command in all the 3 nodes or any one node will work ?

< srvctl stop instance -d crm -i crm1 -f >

Could you confirm the above command to stop service using -f command ?

Should this service also needs to be run on all the 3 nodes or any one node will work ?

Thanks

It is time you started to do a bit of reading, man. You could also try an experiment.
And in particular, you must be clear on the difference between and instance and a service.
