Issues to access SQL Server in Oracle SQL Developer

1. Failed when tried to connect to a SQL server.

Error Message: Status: Failure -I/O Error: SSo Failed: Native SSPI library not loaded. Check the java.library.path system property.

Fix: Copy \x86\SSO\ntlmauth.dll to \jdk\jre\bin

2. How to connect a named SQL server instance.

In SQLServer tab:

Hostname:
Port: /;instance=

Ex: 1433/EDW_SA;instance=edw_dev

Seems it(1.5.4) doesn't support schema.
