Oracle Error Message
ORA-26726: standby and DOWNSTREAM_REAL_TIME_MINE are incompatible
Reason for the Error
An attempt was made to set the standby database and DOWNSTREAM_REAL_TIME_MINE option of the Oracle GoldenGate, XStream or Oracle Streams capture process on the same database.
Solution
Do not attempt to set the DOWNSTREAM_REAL_TIME_MINE option for a Oracle GoldenGate, XStream or Oracle Streams capture process on a standby database. Do not attempt to change a database role to standby if there exists a capture process with the DOWNSTREAM_REAL_TIME_MINE parameter set to Y.
