Oracle Solution for Error ora-01353

ORA-01353: existing Logminer session

What triggered the Error:

An attempt was made to execute DBMS_LOGMNR_D.SET_TABLESPACE while a Logminer session(s) was active.

What should we do to fix it:

First cause all Logminer sessions to be closed. A Logminer session can exist as a result of executing DBMS_LOGMNR.START_LOGMNR or as the result of using Oracle features such as Data Guard SQL Apply or Streams which use Logminer. Next, execute DBMS_LOGMNR_D.SET_TABLESPACE.
