Anyone have experience dealing with JAVA and isolation levels? The concern or talk at this shop is how to handle current old COBOL code with new JAVA code with record locks. All Cobol code runs batch mode. Reads daily transaction file to update files. The new world, Java, will be interactive update real time code. The business does not want to re-write current COBOL (which I do not agree with). Actually, the data base needs to be redesigned.
