Change Oracle JDBC Thin Client Identifier

When connecting to Oracle the JDBC driver identifies itself as "JDBC Thin Client" to Oracle (in v$session as the 'program'). There is also a 'ClientInfo' column in v$session that might be used for this, but it's always empty.

We have a need to identify different applications connecting to Oracle (which are running on the same host, so the 'machine' column in v$session is all the same), so is it possible to change how the Oracle JDBC Thin Client driver identifies itself (so we could put the 开发者_如何学JAVAapplication name in, for example)?

Or is there a recommended way to do this? One restriction is that we're doing this within Struts for some of the applications, which is handling the connection setup internally.

[Identical to this answer]

java.util.Properties props = new java.util.Properties();
props.setProperty("password","mypassword");
props.setProperty("user","myusername");
props.put("v$session.osuser", System.getProperty("user.name").toString());
props.put("v$session.machine", InetAddress.getLocalHost().getCanonicalHostName());
props.put("v$session.program", "My Program Name");
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
Connection conn=
    DriverManager.getConnection("jdbc:oracle:thin:@myhostname:1521:mysid", props);

SQL>select username,osuser,program,machine
from v$session
where username = 'ROB'; 

USERNAME  OSUSER       PROGRAM             MACHINE
--------- -----------  ------------------  -----------
ROB       rmerkw       My Program Name     machine

At application level you can use the following methods to set client_info, module and action in v$session:

dbms_application_info.set_client_info
dbms_application_info.set_module
dbms_application_info.set_action

There is also an Oracle function:

dbms_application_info.set_client_info('Client Info'); 

which sets the ClientInfo column in v$session.
