Extracting DBDs and PSBs using IMS Catalog Node
The IMS Catalog Node introduces the ability to discover and extract IMS information from the IMS Catalog database in the IBM Data Virtualization Manager for z/OS studio.
Before you begin
The IMS Catalog node appears in the IBM Data Virtualization Manager for z/OS server when the following conditions are met in the server configuration:
- DBCTL or ODBA access is configured in the server IN00 file
- IMS Catalog maps are installed in the AVZMAPP DD concatenation.

About this task
The IMS catalog implemented as a standard IMS database contains information about the DBDs and PSBs. The studio supports extracting IMS Database Definition (DBD) and IMS Program Specification Block (PSB) source from the catalog database as an alternative to the pre-existing DBD and PSB extract from the source libraries. Before creating a virtual tables for IMS, you need to extract DBDs and PSBs. The studio supports extracting DBD and PSB source from the catalog database as an alternative to the pre-existing DBD and PSB extraction from the source libraries.
