Oracle Error Message
ORA-16212: number of processes specified for SQL Apply is too great
Reason for the Error
Logical standby apply engine was started with more processes requested than are available.
Solution
Adjust the values of the initialization parameters PROCESSES or the MAX_SERVERS parameter seen in the DBA_LOGSTDBY_PARAMETERS view. If you did not specify MAX_SERVERS, but instead specified PREPARE_SERVERS and APPLY_SERVERS through the dbms_logstdby.apply_set procedure, you will need to decrease either one or both of them.
