Recovery Mode

Syntax:

machadmin -u --recovery=[simple | complex | reset]

The recovery mode is as follows:

simple: If there is no power loss when the server is running, simple recovery mode is run by default.
complex: The complex recovery mode takes longer to execute than the simple mode. It is executed by default when restarting after the power is turned off.
reset: When recovery is not performed in simple or complex mode, all data in all tables are checked to recover the database. In this case, some loss of data may occur.

Server Normal Shutdown
