Hi,

In a situation where I have a client trying to access SID=ACCT1 which is part of a RAC configuration, and the server services ACCT1 fails does an other member of the RAC accept connection requests for ACCT1?

 

Thanx Scott

no, if you want to failover you should use the service=xxx.

Hi,

Well along with the service you have to configure a TAF enabled connection string at client side only then your connections can be taken by other nodes of RAC in case of failure. A typical example (from oracle corp.) of TAF enabled connection string is as follow:

db.us.acme.com=
(description=
(load_balance=on)
(failover=on)
(address=
(protocol=tcp)
(host=db1)
(port=1521))
(address=
(protocol=tcp)
(host=db2)
(port=1521))
(connect_data=
(service_name=db.us.acme.com)
(failover_mode=
(type=select)
(method=basic))))
