This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
We have a Java process that pings the DB (mainframe DB2) at a predefined frequency. If Java process finds some data in DB it reads and processes that data and inserts the data in IBM MQ using JMS.
We are now planning to migrate it to WAS with support for Load Balancing and Clustering environments. We have decided to use Spring Batch Framework.
Now in a multi clustered environment, suppose if some data is there in DB2 and is updated in MQ by java program running in one cluster. How can we ensure that once data is retrieved from one cluster, it should not be repeated by other java program running in differnet cluster. Otheriwse it will lead to duplicate data in MQ by differnet clusters.
May be if we put some flag checks in java to comply to it. But in a multi clustered environment, how we can achieve this.
