Submitting DBD definitions to IMS systems that support DDL
If the IMS system that you are connected to supports DDL, you can submit new or changed definitions for IMS databases (DBDs) directly to IMS™ by using the Submit Changes to IMS option. IMS Explorer generates the necessary DDL CREATE or ALTER statements and sends them to IMS through the JDBC driver. To generate the DDL, IMS Explorer compares the resource in the local project with the resource in the IMS catalog.
Before you begin
The IMS system that you are connecting to must support DDL and the DDL support must be enabled. DDL is supported by IMS 14 and later systems that are configured to manage application control blocks (ACBs) in the IMS catalog. For more information about enabling support for DDL and the IMS management of ACBs in an IMS system that supports these functions, see IMS management of ACBs.
Before you submit changed database definitions to IMS, understand the impact of the changes you are making to the IMS database. Some database changes require you to unload and reload the database in the z/OS environment. For more information about changing record segments, see Modifying IMS databases

What to do next
To activate the pending database changes in IMS, issue the IMPORT command to load the updated ACBs into the online IMS™ system.
