Oracle Solution for Error ora-16212

ORA-16212: number of processes specified for SQL Apply is too great

What triggered the Error:

Logical standby apply engine was started with more processes requested than are available.

What should we do to fix it:

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.
