Setting up date chunking parameters for validation

For performance reasons, we recommend that each validation is set up to use a date field so that the processing is done in chunks based on the date field. The default number of records to process for each date chunk during validation is 1.5 million. To change this setting, set up MaxRecordsPerValidationDateChunk configuration parameters. You can set up a configuration parameter that applies to all replication sets in an application data area or the tenant environment data area, and you can set up configuration parameters for specific replication sets or specific replication set and replicate name combinations in the application data areas.

If you do not use a date field to define date chunks, the validation process uses the default value of 1.5 million for the maximum records to process or, if that default value has been changed in the MaxRecordsPerValidationDateChunk configuration parameter, it uses that value. The validation fails if there are more records to process than the number specified as the maximum number of records to process per date chunk.

  1. Change the default for an application data area or the tenant environment data area.
    1. In the Administration Console, select Configuration Parameters.
    2. Click the All Parameters Keys tab and select MaxRecordsPerValidationDateChunk key.
    3. Click Create Parameter From Key.
    4. Specify a number in the Value field to indicate the maximum number of records to be included per date chunk for validation, which default is 1.5 million.
    5. On the Defined tab, select the entry with the of MaxRecordsPerValidationDateChunk key and click Submit.
  2. To set up a MaxRecordsPerValidationDateChunk configuration parameter that applies only to a replication set or only to a replicate name within a replication set:
    1. In the Administration Console, select Configuration Parameters.
    2. Click the Defined Parameters tab and click Create.
    3. Specify this information:
