Achieving your goals with ALTER and Change Manager
Before products like ALTER or
BMC AMI Change Manager for Db2
were developed, changing the data structures in a Db2 environment was, at best, difficult.
The process was also complex, tedious, time consuming, unreliable, and error prone. Whether working in a single Db2 subsystem or in a large, multiple-Db2 subsystem environment, the DBA must manage a large number of objects with complex interrelationships.
This section describes how ALTER and Change Manager can automate and simplify the goals of changing data structures and migrating structure changes.
