RC/Migrator for DB2 for z/OS
Issue/Introduction
RC/Migrator for Db2 for z/OS (RCM) has ALTERATION and COMPARE types of strategy. While they are each defined in a different way, both produce the
end result of Db2 Database objects being altered. Sometimes alterations to objects can contain many changes which can be hard to keep track of when preparing the alteration.
Resolution
When a RCM COMPARE or ALTERATION strategy has been created , there is a list of objects to be altered.

When editing an object on the list with an "E" in the "S" column of a compare strategy or the "CMD" column of an Alteration strategy, there is a command called COMPARE.
This command displays a BEFORE and AFTER value for each attribute in the object so that the user can see at a glance what has been changed and what will be implemented

The screen report below shows the after/before attribute values that have been altered from the original object on the catalog.
It can also show when columns are deleted or inserted or updated.
This can be helpful as a reviewing tool to check if all required changes have been made.

In the example above the next opportunity to see the changes to be made is when the Analysis of the strategy has been produced.
The Analysis contains the "ALTERATION CHANGE ANALYSIS REPORT" for Alterations and "COMPARE FACILITY CHANGE ANALYSIS REPORT" for Compare reports.
