The IMS TM EXIT Capture agent is an IMS Transaction Monitor Exit that captures segment changes as they are committed within a IMS online transaction and/or IMS BMP job. It writes the captured data to a z/OS LogStream using Connect CDC (SQData) own iCDC record format. The CDCzLog Publisher then manages the captured data in the LogStream until it has been consumed by Engines, ensuring that captured data is not lost until Engines, which may operate on other platforms, signal that the data has been applied to their target datastores.
