I'm having a problem understanding how TAF to a standby database in
jdbc would work. I currently have a production database with a
standby database. I understand that I need to set some failover
settings in the tnsnames.ora file and use the thick java jar files.
What I don't understand is exactly how this would work.
Suppose I have database on machine A and standby on machine B with TAF
set up in the tnsnames files on both machines. Now suppose I have a
jdbc app running on machine C. If machine A fails, how does my jdbc
app access the tnsnames failover information? How does it know to go
to machine C? Does this only work if machine A stays up with the
listener running? Can anybody shed some light on how this works?
