This is possible if the COBOL program uses REDEFINES on its data structures and places invalid COBOL number data in variables accessible by Oracle as COMPs. Update statements may not update rows expected if a CHECK constraint is defined and the table is analyzed and the CHECK constraint compares table columns

Tutorial: Spring MVC + Security + Hibernate + MySQL

This was because the sql script from your post starts the increment at 5 for the tables, but the sql insert into the join table links the user with id 1 and id 2. The question is how do i add css styles to this example? I think we need to map the css somehow, i saw on google some example by using servlet mapping, but cannot make it work in this example

This window will either be the Java process that runs as a CMD window when WebLogic is launched as a separate process or service, or it will be the server log window when running WebLogic from Eclipse. However, there may be occasions during development or staging that you will want to run a local copy or different version than the one loaded from the modules directory - I have not tested this scenario yet, a test of the 3 use cases will be required

You can reduce the number of round trips to the database, thereby improving application performance, by grouping multiple UPDATE, DELETE, or INSERT statements into a single "batch" and having the whole batch sent to the database and processed in one trip. By default, when using distributed transactions with XA, the driver will set the UsingXA flag to true and exceptions will be raised when you want to do anything with your logical connection that might require a transaction

Great article Javin, Though I agree that JDBC drivers especially MySQL JDBC Drivers cause some classloader memory leak in tomcat, I am not fully agree with solution of putting JDBC drivers on Tomcat lib. Another common culprit is ThreadLocal, avoid using it until you need it absolutely, if do you make sure to set them null or free any object ThreadLocal variables are holding

Memory Leak in tomcat due threads are not kill while stopping tomcat (Tomcat forum at JavaRanch)

Which isn't a Tomcat memory leak, it's a case where when a webapp is redeployed memory from the PermGen pool isn't freed due to classloader ambiguities. If you see 100 after you have sent 100 messages, then you need to investigate further (in this case I'd suspect that the API that is sending these messages -whatever that means- is not being used correctly)

Regards, Vicky vicky September 16th, 2010 on 6:44 pm Hi Jay, There is also another issue in one of our environment, when we increase the data source pool capacity from 160 to 200 we receive ORA errors saying No appropriate TNS handler found.

java - To prevent a memory leak, the JDBC Driver has been forcibly unregistered - Stack Overflow

Yes, Tomcat 7 does automatically deregister it, but it that REALLY taking control of your code and a good coding practice? Surely YOU want to know that you have all the correct code in place to close all your objects, shut down database connection pool threads, and get rid of all warnings
