Once this occurred, using the ZUDFM DISPLAY command to view the contents of the CDC TPFDF database index would result in an OPR-IDB013C. The corrupted entry would only be created if the day change occurred right before the CDC application started writing the multiple records for the interval to the TPFDF database. Since it would take a new timestamp right before it started the writing process, it would be using an algorithm string for the TPFDF database, but no matching algorithm index would exist. This would cause a corrupted index to be created. SOLUTION: There were two things done to correct the problem: a) Make sure that there is one and only one timestamp per collection interval. b) If TPFDF is being used as the storage medium, make sure that a valid index entry exists for the current date.
