(Sheeri Cabral) As I putter around the MySQL INFORMATION_SCHEMA, I am finding lots of undocumented behavior for fields that should be straightforward. For example, the VIEWS table holds information about views, and the VIEW_DEFINITION field contains the view definition, right?
Indestructible Cluster part 2
(Johan Andersson) In part 1 we got the cluster monitoring up and running. Indeed a good step forward into taming Cluster. This time we are going to add process management to our solution – if a node fails (ndbd, ndb_mgmd, mysqld etc) fails, then it should be automatically restarted.

Indestructible Cluster part 1
(Johan Andersson) Version 1.0 of CMON (gpl license) has now been released. It is dead easy to use and gives you a lot of helpful information about the state of the cluster. Memory utilization, statistics etc.
Why you do not use GRANT ALL ON *.*?
(Ronald Bradford) Why you do not use GRANT ALL ON *.*? I was with a client today, and after rebooting a MySQL 5.0.22 instance cleanly with /etc/init.d/mysqld service, I observed the following error, because you always check the log file after starting MySQL.
