In MySQL 5.5, the InnoDB Plugin is the default version and it's compiled in.
|
|
|
6f9931 |
In this case, the plugin cannot be uninstalled and we get error when trying
|
|
|
6f9931 |
to do so:
|
|
|
6f9931 |
|
|
|
6f9931 |
mysql> uninstall plugin innodb;
|
|
|
6f9931 |
ERROR 1305 (42000): PLUGIN innodb does not exist
|
|
|
6f9931 |
|
|
|
6f9931 |
But the error message is misleading. The plugin does exist, it just cannot
|
|
|
6f9931 |
be installed because it's not dynamically loaded.
