suppose I have an entry like this in tnsnames.ora ...

ESSNCS =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = apollo)(PORT = 6521))
(ADDRESS = (PROTOCOL = TCP)(HOST = aquarius)(PORT = 6521))
)))

I try to connect to ESSNCS and (assume) apollo instance is down, it seems sqlnet takes a long time to see if it will connect to apollo and then connect to aquarius. But if apollo machine is down (i.e. no network connectivity), it promptly goes to aquarius.

How can we reduce the time that sqlnet waits to make a connection to apollo and immediately goes to aquarius? I'd like that time to be about 5 to 6 seconds ...

Thanks
Raj
