When accessing any objects from the Schema Browser, the following error is thrown and no data on the right-hand side is displayed:
The application has encountered a problem. We are sorry for the inconvenience.
The system cannot find the path specified.
The long TNS format is used to connect to the database.
e.g. (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1524)) ) (CONNECT_DATA = (SERVICE_NAME = dbname) ) )
WORKAROUND 1
Add the TNS entry to the tnsnames.ora file and access the database via the drop down list.
WORKAROUND 2
From the login window, connect using the Direct tab and enter the connection details such as host, port, and service name.
WORKAROUND 3
