Oracle Solution for Error ora-26726

ORA-26726: logical standby and DOWNSTREAM_REAL_TIME_MINE are incompatible

What triggered the Error:

attempt was made to set the logical standby database and DOWNSTREAM_REAL_TIME_MINE option of the Streams capture process on the same database.

What should we do to fix it:

not attempt to set the DOWNSTREAM_REAL_TIME_MINE option for a Streams capture process on a logical standby database. Do not attempt to make a database logical standby if there exists a Streams capture process with the DOWNSTREAM_REAL_TIME_MINE parameter set to Y.
