The Plugin must loaded whenever the MySQL database server is started. As we saw earlier, there are several ways to configure MySQL to use the Plugin rather than the built-in InnoDB: in the option file, with mysqld command-line options, or with INSTALL statements after the server starts.

To ensure that you do not accidentally revert to the older InnoDB, be careful to carry any configuration file, command-line options, or post-startup commands forward in the future, such as when transitioning from a development system to a test system, setting up a replication slave, or when writing new mysqld startup scripts.
