    We normally see this error when the REDO log got archived.


    1. Try to reload the task from time stamp, from the drop down next to run, advance run option and reload from time stamp.


    2. could you check with your DBA if the REDO log got archive, if so can they restore the redo log?


    3. What is the retention period of redo logs?


    4. . Does the Replicate user for the Oracle Endpoint have all the permission according to the user guide.
