"number of processes specified for SQL Apply is too great"
*Cause: Logical standby apply engine was started with more processes
requested than are available.
*Action: 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.
