Connection to Oracle without a username or password

Question

Oracle has this concept of allowing database users to be identified by the operating system user who is running the program that is connecting to Oracle. See here.

This allows you to do, as that user on a unix machine for example, a command such as:

sqlplus /

I am attempting to write a Java program for Oracle 10.2 which connects without a username or password. The obvious choice of url:

jdbc:oracle:thin:/@localhost:1521:MYDBSID

doesn't work, giving an error (Sorry I don't have the error available right now).

I have attempted many other forms of doing this as well, but with no luck.

Does anyone have any suggestions on how I can connect a Java program to Oracle using the OS identification method?

Answer 1

The JDBC Thin driver is a 100% pure Java implementation that cannot collect the needed information from the operating system.

The JDBC OCI driver can do this! Use jdbc:oracle:oci8:/@MYDBSID, it will require that the Oracle driver be installed on that machine, not a problem if this is a server (and is faster to boot and supports many more features than the thin driver)
