We would like to drop 2 databases and reclaim the ibdata space that the 2 databases took up. What is the best way to do this? > > QUESTION 2 : Can you have multiple MySQL Instances that contain one database and a seperate ibdata spaces? Is this the best way to create seperate ibdata files for each database? What would you recommend? > please see http://www.innodb.com/ibman.php#Multiple.tablespaces That solves the disk allocation problems. > QUESTION 3: How can you defrag a database instead of a table? There is no such command. You have to write a script for that. > We have found that you can defrag a table: "From MySQL Manual: The way to do the defragmenting is to perform a 'null' alter table operation ALTER TABLE tablename TYPE=InnoDB." We would like to do this for the complete database. > > Thanks again for any help. > > Respectfully, > > Mike Best regards, Heikki Tuuri Innobase Oy http://www.innodb.com Foreign keys, transactions, and row level locking for MySQL InnoDB Hot Backup - a hot backup tool for InnoDB which also backs up MyISAM tables Order MySQL technical support from https://order.mysql.com/ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
