CICS CSD Information Handling

Online programs that run under CICS® require access to external data sources, such as files, tables, and queues, cannot rely on jobs to perform the mapping to physical data source entities. CICS provides a way to define such mapping and saves the mapping information in the CICS System Definition (CSD) file.

It is recommended to choose only one method to obtain CSD information in a project. For example, if the CSD information is obtained by using IBM AD Connect for Mainframe, and afterward the user decides to use an exported CSD report, the previous CSD information is automatically deleted. For more information, see Deleting data from the repository.
