I just created a new database with SID=OTTR. I can connect to it using the connect string 2:OTTR

In tnsnames.ora I have an entry
ottr.world =

	(DESCRIPTION =
		(ADDRESS_LIST =
			(ADDRESS =


				(COMMUNITY = tcp.world)

				(PROTOCOL = TCP)

				(Host = whittle)

				(Port = 1521)

			)
			(ADDRESS = 


				(COMMUNITY = tcp.world)

				(PROTOCOL = TCP)

				(Host = whittle)

				(Port = 1526)

			)
		)
		(CONNECT_DATA = (SID = OTTR)
		)
	)

But when I connect to the name ottr I get: ORA-12505: TNS:listener could not resolve SID given in connect descriptor Received on Thu Jan 09 1997 - 00:00:00 CST
