Phase 1: Changed Data Stores Identification

Phase 1 of the Life Cycle, Changed Data Stores Identification, involves the following events:

Flat file population. Use the Toolkit to populate the IMPSRC, which contains a list of data stores and corresponding I/O areas that have been modified.
Note: For more information, see Load IMPSRC for Life Cycle in your Toolkit (z/OS) guide.
File changes are identified. All copybooks included in the specified PDS or DB2 owner tables are scanned and compared with the structures already defined in the Data Manager Knowledge Base.
A sequential guide file is created. This file is a list of information about the matches between the data stores included in the Data Manager Knowledge Base and the copybooks, or of the modified DB2 tables.
The guide file information is accessible in the Work with Changed Data Stores area.

Note: The guide file is followed by the IMPSRC file, which is created from the job Load Sequential for Life Cycle to recognize the modified sources. This Life Cycle feature of the toolkit can be omitted if the list is produced by your development management tool.

Before proceeding to the next phase, the list in the Work with Changed Data Stores area should be examined in order to confirm it and to possibly integrate additional information.
