PowerExchange Condense

PowerExchange Condense

PowerExchange Condense creates condense files that contain a condensed version of the changes that were captured by an ECCR and stored by the PowerExchange Logger. PowerExchange Condense processes changes for a single data source. You can run multiple PowerExchange Condense jobs.
When you create a capture registration, specify either full condense or partial condense. For full condense, PowerExchange creates VSAM condense files that contain all successful changes. Full condense processing rationalizes all insert, update, and delete activity into the final image of the row or record. Transactional integrity is not maintained in full condense files.
For partial condense, PowerExchange creates sequential condense files that contain all successful changes. Transactional integrity is maintained in partial condense files.
When using PowerExchange Condense, you extract the change data from the condense files rather than from the PowerExchange Logger log data sets.
