Hi,

Sometimes You can get “ORA-12533: TNS:illegal ADDRESS parameters ” error.

 

Details of error are as follows.

ORA-12533: TNS:illegal ADDRESS parameters
Cause: An illegal set of protocol adapter parameters was specified. In some cases, this error is returned
when a connection cannot be made to the protocol transport.
Action: Verify that the destination can be reached using the specified protocol. Check the parameters
within the ADDRESS section of TNSNAMES.ORA. Legal ADDRESS parameter formats may be found in the Oracle

layer (such as DECnet object names) are vulnerable to this error if not properly configured or names are misspelled.
