On V9.5, I have…

This parameter driven script will echo display the parameters it needs to operate.  You can test it manually and then when you have identified the configuration parameter you want to maintain, the minimum value you would like to maintain, the…

Well here I am going to show how to retrieve data from a table as an XML document.  Using the table set of tables from the previous post lets retrieve all the order details for a given customer.  Here is a stored procedure that will take customer_id as an input and then return an xml document that has all the orders and…

On this one I am going to show you how to insert data using XML as a value.  As my previous article show its easy to insert to child table , but you have to insert one row at a time. Well what if we have multiple child rows…

You may have seen  the recent video here on ChannelDB2 that introduces auditing of DB2 changed data.  If you're interested in giving it a quick try, it's easy set up a simple configuration and see what you get. That's what I'm going to show you how to do in this post.  It should take about 5-10 minutes.  We'll use DB2's SQL Replication.  It's provided with all editions of DB2 and InfoSphere Warehouse…

A couple of months ago, IBM announced enhancements to its data replication in support of DB2 v10 for UNIX and Windows.  This month, IBM released an update to its Q Replication Dashboard that supports those enhancements and much more.  In fact, most the Dashboard's enhancements can be used with Q Replication for DB2 z/OS, too.  This post takes a quick look at…
