第19题:
Execution of the FLUSH LOGS statement
Starting of the SQL thread
Reaching the slave_pendign _jobs_size_max limit
Execution of FULSH TABLES WITH READ LOCK

第20题:
RMAN will attempt to make the backup run as fast as possible without any IO limitations.
RMAN will automatically restrict the number of channels in use to one.
RMAN will spread the backup IO over the total duration stated in the backup command.
RMAN will skip any datafile that currently is involved in an IO operation. RMAN will retry backing up the datafile later and an error will be raised at the end of the backup if the datafile cannot be backed up.
Datafiles will be backed up; those having the lowest current number of IO operations will be backed up first.
第21题:
The slave was created with mysqldump –u root –p – skip-lock-table—all-databases > /data/data.sql
The slave user does have INSERT, UPDATE, or DELETE permission and cannot execute the write_rows function
For tables with UNIQUE keys, statement-based replication must be used maintain integrity
The root user on the slave has executed FLUSH LOGS, causing the relay-log to doublewrite
The applications have the SUPER privilege, which allows them to update rows
