When connecting using a JDBC/thin 10.2.0.3 driver using the following URL:
(ADDRESS = (PROTOCOL=TCP)(HOST=host2)(PORT=1521) )
( ADDRESS_LIST = (ADDRESS = (PROTOCOL=TCP)(HOST=host3)(PORT=1521) )
(ADDRESS = (PROTOCOL=TCP)(HOST=host4)(PORT=1521) )
you get the following error:
Error : IO Exception : End of TNS data channel
The same connection works fine with JDBC 10.2.0.4
Using multiple ADDRESS_LIST clauses is useful in a DataGuard environment, when both the primary and secondary databases are RAC.
