I have 2 databases running on different virtual servers. I have some database processes running on one node. These processes connect to Database Gateway (PG4MQ) and process the messages.
I need to start the process manually. I need to write a script that will monitor the node on which the processes are running and if the node is down or not running then these process will automatically start on the other node.
Can someone tell me is this feasible or not, if feasible then how can this be achieved?
Databases installed on RHEL 5.8. OEM, Grid, DBCA and Oracle Net services are not available.
