Hi All,

This is my tns file,while connecting to the server database i am getting this error number
ORA-12545. but keep on trying again and again i am able to connect.
Plese help me on this issue.

Old:

dmsrp01r.world =
(description =
(address = (protocol = tcp)(host = xyz1.org)(port = 1521))
(address = (protocol = tcp)(host = xyz2.org)(port = 1521))
(load_balance = yes)
(connect_data =
(server = dedicated)
(service_name = dmsrp01r)
(failover_mode =
(type = select)
(method = basic)
(retries = 180)
(delay = 5)
)
)
)
-----------------------------------------------------------

NEW:
dmsrp01r.world =
(description =
(address = (protocol = tcp)(host = xyz1.org)(port = 1521))
(address = (protocol = tcp)(host = xyz2.org)(port = 1521))

Code: [Select all] [Show/ hide]

ORA-12545: Connect failed because target host or object does not exist
 *Cause: The address specified is not valid, or the program being
 connected to does not exist.
 *Action: Ensure the ADDRESS parameters have been entered correctly; the
 most likely incorrect parameter is the node name.  Ensure that the
 executable for the server exists (perhaps "oracle" is missing.)
 If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the
 host name to a numeric IP address and try again.

}
Regards
Michel

It could be Oracle bug.

Unwilling or incapable to Read The Fine Manual yourself?
Why should I write here what is already documented at http://tahiti.oracle.com?

we don't know what you are doing so we can't speculate what exactly might be wrong.
error of commission?
error of omission?
We could only guess at which of the above should be answered "YES".
