Special considerations for overtime mode

Be aware of the following considerations as you use overtime mode:
  • Multiple instances of DB2 objects

    Log Master refers to the version of a DB2 object that exists between one create action and a following drop action as an instance of that object. Depending on the time frame of your log scan, and the times when the object is dropped or re-created, Log Master can encounter log records related to multiple instances of the same DB2 object.

  • Row completion processing

    By default, Log Master does not perform all row completion processing when it runs in overtime mode. Therefore, for Log Master to retrieve data related to an old object, one of the following conditions must exist. If neither condition exists, Log Master attempts to perform some row completion, but might issue error messages when it cannot complete all log records.

    • The old object was defined with Data Capture Changes (DCC) during your selected time frame. If DCC was turned on, the selected log records are complete, and Log Master does not perform completion processing.

    • You provide image copy data sets that contain the old objects that you require, and you tell Log Master to use them by setting a run time option.

      If the old objects were not defined with DCC, and you have image copies that contain the old objects that you reference, you can take the following actions to increase the chances of successful row completion processing, but Log Master might not be able to complete the log records.

      1. On the Work ID Run Time Options panel, type Y in the Attempt Completion field.

      2. In the Specify Image Copies field, to specify the names of image copy data sets that contain the old objects, type E.

      3. Enter the names of image copy data sets that contain the selected objects. Depending on the activity related to the old objects, you might need to specify multiple image copy data sets.
