Home -> Community -> Mailing Lists -> Oracle-L -> RE: An OPS & tnsnames question
Look at Transparent Application Failover as a Net8 option. You'll need to determine Oracle Client compatibility / requirements with such!

Dear list !
I've got an OPS database named OPS with 2 instances OPS1 and OPS2 .
I want the users to connect to OPS1 and ONLY if it is down , to connect to
OPS2.
It's Oracle 8.0.5.1 on NT4.
I put the following lines in clients' tnsnames.ora file :
OPS.world = (DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp) (HOST = DB1) (PORT = 1526))
(CONNECT_DATA = (SID = OPS1))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = tcp) (HOST = DB2) (PORT = 1526))
(CONNECT_DATA = (SID = OPS2))
)
This works perfectly fine except for the case when OPS1 instance is down ,
but the listener is up.
Then clients try to connect to OPS1 and fail - "Oracle not available" .
When i bring the listener on OPS1 host down - everybody perfectly connect to
OPS2.
Is there a solution ?
Thanks a lot in advance !
