IGNORENOCHANGEUPDATES Parameter

IGNORENOCHANGEUPDATES Parameter

Controls whether the Adabas ECCR ignores records for which update operations did not change the data.
IGNORENOCHANGEUPDATES={
N
|Y}
  • N
    . The Adabas ECCR passes all records to the PowerExchange Logger, including the records with unchanged data.
  • Y
    . The Adabas ECCR checks the before image and after image of the source data to determine if the data changed and then passes only the changed records to the PowerExchange Logger. The ECCR ignores records for which data did not change. Use this setting to reduce the number of records that are sent to the PowerExchange Logger.
Default is N.
  • Use this parameter to configure the Adabas ECCR to ignore the many unchanged records that the ADAORD utility typically produces for online reorder operations.
  • When you REORDER Adabas files, Adabas logs the before and after images of unchanged records to PLOG files. Unless you configure the ECCR to ignore these records, the ECCR captures the unchanged records from the PLOG files.
