ORA-01307: no LogMiner session is currently active

ORA-01307: no LogMiner session is currently active


Cause:


A select was issued from v$logmnr_contents without first invoking the dbms_logmnr.start_logmnr() procedure. Otherwise, dbms_logmnr.end_logmnr() was called without a prior call to dbms_logmnr.start_logmnr() or dbms_logmnr.add_logfile()



Action:


Invoke the dbms_logmnr.start_logmnr() procedure before issuing a select from the v$logmnr_contents view.
