Oracle connection problem

Maybe is smth wrong with the name of your db connection string; maybe u should escape “/”, trying to do it with two “//”.(it’s an “Invalid connection string format” - error message ) or simply the format should look the way it suggests: host:port:sid

Hope it helps…eventually it will work:)

Your database name looks kind of odd. It looks like a connection
string rather than a TNSnames entry. Generally the database names in
the TNSnames file are single words (often the database SID). Double
check you are using the connection name. If //WASDEV1:1521/D1WAS
really is your connection name, try adding a duplicate entry to the
TNSnames file that doesn't have special characters in it; for example,
try calling this connection FRED.
