Abstract:  The latest improvements in Online Schema capabilities introduced in DB2 10 for z/OS represent something more like a Revolution rather than an enhancement to the OLS Evolution capabilities we've been used to seeing in successive releases of DB2. For the first time DBAs can register the changes they wish to make and then implement them at a time of their choosing using an Online Utility rather than having the object concerned move into an Advisory Status which may cause serious Performance Issues or worse. This session will describe the new OLS capabilities, how to use them and some pitfalls which may not be immediately obvious when you read the new features list. Come and listen to the way of the future as far as making Changes to your DB2 database structures is concerned!
