There are many different change commands and several ways to construct
them in DB2® Change Management Expert.
DDL, data preservation commands (export and import commands), and rebind commands
are all different types of change commands.
DDL can be:
- Generated between any two models. This is called Delta DDL. Typically
this is done between the base model and target model, more generally two versions
of the same model. But they can be generated between two heterogeneous models
in some cases.
- Generated from a single model. This is useful to recreate a model.
- Generated outside of DB2 Change Management Expert by
using another tool. For example, db2look.
- Created manually by using the Change Command Editor.
- Imported into the project and into a deployment script by using the Change
Commands tab.
Supported DB2 commands,
utilities, and system commands can be:
- Generated based on DDL using a wizard in the deployment script.
- Composed manually by using the Change Command Editor.
- Imported into the project and into a deployment script by using the Change
Commands tab.
The list of supported DB2 commands, utilities, and system commands includes:
- export
