SomeTimes I get this error in my application
As per some IBM references, the following is the reason for this error
it looks like the connection object is closed by a thread and still another thread is trying to use, My solution for this is to change my datasource configuration to make it unsharable instead of sharable then different threads will not use the same connection object
any comment from your side or any other solution for this issue
