Change Oracle JDBC Thin Client Identifier

Question

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 application 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.

Answer 1

Identical to

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);

query v$session

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 dbms_application_info.set_module and dbms_application_info.set_client_info to set clientinfo,module,action in v$session

Answer 2

There is also an Oracle function:

dbms_application_info.set_client_info('Client Info');

which sets the ClientInfo column in v$session.
