If you use one of the BMC Software products, ensure that the product meets the minimum version that PowerExchange requires for IMS synchronous CDC, as described in the "IMS Synchronous Change Data Capture" chapter of the

PowerExchange CDC Guide for z/OS

.

Also, note that the current PowerExchange version has been certified with the following BMC product versions, which provide the CRG code:

If you use a product version earlier than the certified version, consider upgrading the product to the certified version.

If you use the CRG software, after you upgrade PowerExchange, run the CRGUMOD or CRGCLINK job in the

hlq

.SAMPLIB library again to install DBRC modifications. Otherwise, events such as abends might cause change capture to fail in the DLIODDC

x

module when the IMS synchronous ECCR tries to capture changes for a source segment. After you run the CRGUMOD or CRGCLINK job, restart the IMS control region.
