PowerExchange 10.5.5 contains components of the BMC Software BMC AMI Online Reorg for IMS and BMC AMI Database Integrity for IMS products. PowerExchange provides the latest available version of these components in support of IMS 15.3 and IMS 15.4.

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

.

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 CDC to fail in the DLIODDCx 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.
