Get Ora-01017 "invalid username/password" error trying to connect to Oracle database using TCP/IP
Description
When trying to connect to an Oracle database using TCP/IP, the following error is given.
"Connection failed because of the following error: "ORA-01017: invalid username/password; logon denied""
Resolution
RESOLUTION #1: Make sure the username and password that are being used are correct. If possible, try connecting to the Oracle database using SQLplus and see if the same error is returned. If same error is returned in SQLplus, there may a problem with the account.
RESOLUTION #2: Connect using Native Client, instead of TCP/IP. This can be selected in the "Select Data Provider" window of the Reverse Engineering Wizard.
