Merging existing Db2 data into the group
Although Db2 cannot automatically merge catalogs, you can merge existing Db2 subsystems into a data sharing group. Consider carefully a decision to merge existing Db2 subsystems.
Merging is a very complicated process. It involves not only the
physical issue of moving data, but also many other management issues,
including:
- Naming conventions for users, plans, packages, databases, tables, views, and more
- Authorization techniques
- Backup and recovery conventions
- Availability practices
Before you consider merging existing Db2 subsystems into a single data sharing group, ask yourself the following question: Why are the Db2 subsystems separate now?
