Replication of invoked features such as user-defined functions (UDFs) and stored programs (stored functions and procedures, triggers, and events) was re-implemented in MySQL 5.1.18 to provide the following characteristics:

To determine whether there are any scheduled events on a MySQL server that were created on a different server (that was acting as a replication master), use SHOW EVENTS, like this:

SHOW EVENTS
    WHERE STATUS = 'SLAVESIDE_DISABLED';

Alternatively, you might wish to query the INFORMATION_SCHEMA.EVENTS table as shown here:

SELECT EVENT_SCHEMA, EVENT_NAME, ORIGINATOR
    FROM INFORMATION_SCHEMA.EVENTS
    WHERE STATUS = 'SLAVESIDE_DISABLED';

When promoting a replication slave having such events to a replication master, use the following query to enable the events:

UPDATE mysql.event
    SET STATUS = 'ENABLED'
    WHERE STATUS = 'SLAVESIDE_DISABLED';

If more than one master was involved in creating events on this slave, and you wish to enable events that were created only on a given master having the server ID master_id, use the following query instead:

UPDATE mysql.event
    SET STATUS = 'ENABLED'
    WHERE ORIGINATOR = master_id
    AND STATUS = 'SLAVESIDE_DISABLED';

UPDATE mysql.event
    SET name = CONCAT('replicated_', name)
    WHERE status = 'SLAVESIDE_DISABLED';

UPDATE mysql.event
    SET name = REPLACE(name, 'replicated_', ''),
        status = 'SLAVESIDE_DISABLED'
    WHERE INSTR(name, 'replicated_') = 1;
