For completeness: root@127.0.0.1 [(none)]> set global report_port = 3306; ERROR 1238 (HY000): Variable 'report_port' is a read only variable

Note: I still have a large number of requests for making more variables dynamic. Having to report them one by one, and then waiting and seeing that nothing happens is quite frustrating as a forced restart to change settings is just a nuisance. It would be good to perhaps make a more general look for open feature requests of this type to see which of them could be changed as "it does make a difference". While many of these settings change infrequently, the require to change settings does happen and the work you have to do to avoid applications seeing downtime while re-adjusting configuration settings is noticeable (to us). The developers may think it does not matter but when you manage a largish group of MySQL servers you eventually bump into this and whatever front-end, load balancing system you are using has to handle servers going away for "some time", or the replacement of one server with another.
