Oracle Error Message
ORA-39026: master table is inconsistent on validation string
Reason for the Error
Job cannot be restarted because it failed a validation check. Validation checks are of the form -xx.y where -xx is the value of the PROCESS_ORDER column in the master table where the error was detected and y is the actual validity check for the row.
Solution
Recreate the job. If master table has not been modified, but problem persists, contact Oracle Customer Support.
