Relocate service to another node

edited Aug 4, 2014 10:54AM in Database - RAC/Scalability (MOSC) 4 commentsAnswered

Dear Colleague,

On our RAC with 2 nodes environment, we created one service with name USG21_SRV, the Preferred instances: USG21A and Available instances: USG21B.

This RAC is node A active, node B is not active - means that node B is up but all transactions go to node A.

whenever node A was down, then I need to relocate the service to node B using command " srvctl relocate service -d USG21 -s USG21_SRV -i USG21A -t USG21B "

My Question are :

1) Why do I need to relocate the services manually ?

2) If the services wasn't relocated to another node, what would happen with new connection that connects using USG21 tns entry

Howdy, Stranger!
