Two ports in tnsnames.ora

Hi Gurus,

When there are two ports mentioned in the tnsnames.ora, what does it mean?
The SID and servername is the same.

For example, pls refer to the following entry:

MYDB.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =

(ADDRESS = (COMMUNITY = tcp.world)(PROTOCOL = TCP)(Host = mydb.america.com)(Port = 1521))

(ADDRESS = (COMMUNITY = tcp.world)(PROTOCOL = TCP)(Host = mydb.america.com)(Port = 1526))

)
(CONNECT_DATA = (SID = mydb))
)



Thanks!

Have you checked the listener file, listener.ora?

these port numbers are the default number recommended by oracle corp i.e 1521-1526 so i you can eliminate one
