An IDD application configuration is loosely coupled with the metadata in an MDM-RE System. The configuration contains references to objects in an MDM-RE System. Changes to an MDM-RE System (the addition, modification, or removal of Identity Tables, Searches, and so on) are not automatically reflected in the IDD configuration. For this reason, the IDD validation process is necessary and must be repeated periodically.

Validation is run in the following circumstances:

The following validation levels are available.

valid_ind	Validation Level	Description
-1	Not Validated	The IDD application has not been validated.
0	No Error	No errors or warnings were found during validation.
1	Information	Provides information to the user. No configuration changes are required.
2	Warning	A configuration might need to be changed, but should cause no run-time problems.
3	Error	A configuration error must be fixed. Run-time problems can be expected.
4	Critical Error	Same as Error, but indicates a problem that requires even more urgent attention.
5	Fatal Error	An error that prevents the IDD application from running at all. The application will not be deployed before the error has been addressed.

The application state is controlled by the user in the IDD Configuration Manager. It stores the intended deployment for the IDD application.

active_ind	Name	Description
-1	Not Deployed	IDD application is not deployed. Useful when the application is in development. Changes can be made and saved without the additional overhead of deploying the application.
0	Limited Deployment	IDD application is deployed, but the application will not be displayed in the list of available applications. You must access the application using its full URL ( http://<hostname>[:<port>]/bdd?bdd_name=name ).
1	Full Deployment	IDD application is deployed for full use. It is displayed in the list of applications and users can run the application.

Deployment is the process of taking an IDD configuration and making it available as an application. An application is not deployed if

active_ind

is

-1

for that application.

Deployment occurs in response to the following events:

Event	Description
Application Server Startup	All IDD applications with active_ind that is not -1 are first validated. If the validation level is not Fatal Error, then the IDD application is deployed. At this time, only a partial validation is run to check for fatal errors.
Import / Save	Any time an IDD application is imported or saved, it is also deployed unless its active_ind is -1.
Re-deployment	User re-deploys an IDD application.
