Re: AW: Experiences setting OPEN_CURSORS for Java applications
Hi, I'm not sure about the Interceptor pattern. Log4j is a great package and I make use of it within JDBC Expert. I started using the new logging API in JDK 1.4 but found most developers were using Log4j so I changed. Log4j seems like a much more mature package anyway. I too think it would be a great tool to be used in the development cycle. Ideally I would like every developer to have it installed while they complete their development in the hope that a number of defects can be eliminated early. In reality though, I find that senior developers and data administrators see the most benefits. Particularly database administrators, probably because they are the ones that are called upon to resolve the errors (such as ORA-1000) when they occur. Let me know if you would like a copy, and I'll email it privately to you - its too big to send to the list. Regards, Craig Munday.

AW: AW: Experiences setting OPEN_CURSORS for Java applications
Hi Craig The whole point of an interceptor is basically to add functionality to a certain type or protocol without changing the interface the client works with. In Java, this is usually accomplished by implementing an extra interface to add things like security or billing based on transactions etc. (I've seen this in CORBA first, hence the reference to it). The developer continues working with the same types she/he used to work with. It often comes along with the factory pattern, where a certain object is created and returned to the calling object. The calling object uses the interface of the type it wanted, not being aware of any additional things. I hope that was confusing enough ;) Right now, we just implemented some common PL/SQL packages to deal with logging and error handling etc., but I have to say, the idea to add an extra layer to the JDBC architecture is a great idea. Helps DBAs spotting problems real easy, as you said.

Re: Experiences setting OPEN_CURSORS for Java applications
Hi there, I've supported a number of systems implemented in Java running on Oracle and on nearly all of the projects the developers have asked me to increase the number of open_cursors. In most of the cases I have found that the developers were not using the JDBC API efficiently. The main problem being that Statement and ResultSet objects where never explicitly closed. If the developer does not close these objects explicitly, the garbage collector in the Java Virtual Machine will eventually close them. However the problem is that sometimes the garbage collector does not do this soon enough and you exhaust the number of open cursors you have allocated. Even the most diligent developer's sometimes make subtle mistakes like reassigning ResultSet variables and hence losing the reference to the original ResultSet, as I found out in JBoss4.0 DR2. I've encountered this problem so often that I decided to write a tool (called JDBC Expert) that would help us DBAs (and developers) detect Statement and ResultSet leaks in Java applications. I've found this tool so useful and effective at finding resource leaks that I insist any in house developed or third party Java applications are tested with it before we release them. JDBC Expert installs like any other JDBC driver and does not generally require modifications to your application. The tool analyses how your application is using the JDBC API and reports various types of problems (such as resource leaks). I can send you a copy if you are interested - you will have to forward me your JDK version and details about any app server that you are using. Regards, Craig Munday.
