Re: can we pass OS username while connection Database from Tomcat
Hi, Client want to monitor whether the connection is established from my application or their existing applications. Because all these are connecting the database from APPS user. 1) My Tomcat is installed on a different Linux environment under a user, so if i could at least pass this user then Client can able to identify that the connection is established from my Application. 2) By querying the v$session table in Oracle we can get all the connection information but we can't identify the connections that are created from my application because all the applications are connecting database through APPS user. We can achieve this by creating a new schema and providing all the required permissions to my schema and accessing the database from the created schema but is there any option where we can achieve my requirement. I found that by providing a attribute called 'connectionProperties' in Resource Tag of the context.xml is achieved this. But am not seeing any information about the Program name after connecting to database.

But is it the best solution to fulfill your customer's wishes, that is another question. I believe that you have to think carefully about all the implications, in your application as well as on the performance of the system, before rushing to any kind of solution. For example, would it not be easier for your application to just write a line to some logfile, whenever it accesses the database on behalf of the logged-in user (and read and analyse that file later, and provide that information to your customer) ? If your customer just wants to know who is really using the database and/or how much, that would be enough. If you really want to open the connection to the database under each individual user-id, then it means for example that the database has to know each of those user-id's (and keep them up-to-date). It also means that different user-id's could have different access rights (or none), and that your application would have to take this into account. And so on.. It is not just the fact of opening the connection. It may be the whole design of your application that would need to change. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

not providing the crucial information which would enable someone
to really help you. For example, what Linux user information
(userid) are you talking about ?
Is it the Linux user-id under which Tomcat is running ? That
would probably be tomcat, so that is probably not going to help
you fulfill your customer's wishes.
Is it the user-id of the /user/ of your Tomcat application ? In
that case, how does Tomcat know this user-id ? Do the users login
into your application ? How ? What is the user authentication
mechanism being used, now, at the Tomcat level ?
Does the Oracle database also know this user-id ? How ?
What does One of my client want to monitor the connections
mean, exactly ? what does the customer want to know, and when ?
Is this customer the only user/manager of the Oracle database, or
are there multiple users/managers of the Oracle database ?
