ORA-01321: No Logminer Dictionary for requested start SCN

What triggered the Error:

The requested session start SCN is less than the SCN of any available Logminer Dictionary build. It is not possible to unwind a Logminer Dictionary to the requested start SCN.

What should we do to fix it:

Re-issue the start_logminer request with a start SCN for which a Logminer Dictionary is available.
