You can stop change data capture for all VSAM data sets or a specific data set.
To stop change capture processing for all VSAM data sets, stop the batch VSAM ECCR interface.
To stop change capture processing for a specific registered VSAM data set, deactivate or delete the capture registration and close the data set.
When you stop the change data capture process without stopping updates to the source, you lose change data. To avoid losing change data and rematerializing the target tables, stop updates to the source instead of stopping the batch VSAM ECCR interface.
