The default charset of c is utf8, and that of a and b is latin1. Maybe charset cause size of table increased? -- Thanks & Regards Chylli -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

The trouble with myisamchk is that it requires the server to be offline. This may not be suitable. Do you have a bad area on the disk? The easiest way would be to stop the server briefly, rename the index thus keeping it occupying the potentially bad part of the disk and recreate the index. This w

Re: Replication vs. Clustering

It's important to read the "How much RAM" part if you are running any version lower than 5.1. In 5.0 and lower clusters store all information in memory, which can be a very limiting factor. My experience with replication is that it is fairly quick, in seconds at most rather than minutes. One ty

Do a "show status" and check on what mysql is doing. I would start by looking at: threads_created - if this is high, increase your thread_cache_size. This means MySQL is busy creating and destroying threads instead of reusing them. This can take a toll on the OS. Opened_tables - if this number
