I'm having problems connecting from my Oracle Application server into my Oracle 10g RAC database.

It works when I use the TNSNAMES definition of either:
    (ADDRESS = (PROTOCOL = TCP)(HOST = ###.###.125.147)(PORT = 1521)))
    (CONNECT_DATA = ( =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ###.###.125.148)(PORT = 1521)))
    (CONNECT_DATA = ( =

It only works half of the time when I use the following entry.  I get an "ORA-12170:TNS:Connect Timeout Occurred" error. =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ###.###.125.147)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = ###.###.125.148)(PORT = 1521))
    (LOAD_BALANCE = yes)

And a TNSPING works for all 3 different TNSNAMES entries without fail.

Any thoughts?
