Re: MySql at 100% CPU
No worries :) Good luck with your problem! Apparently not, since no member of the MySql team wants to tell me and this mailing list what scenario's will cause a low-load MySql system lock at 100% CPU for hours on end. Another of my servers has just entered this mode about half an hour ago. I include the xload graph just to show I am not imagining this! Another guess: these servers are quite new and growing at several gig a week. Does InnoDB have some mode whereby it checks all tables after some threshold of time, size or row count? Which is likely to take hours and put the CPU load at 100%? If four of my ten MySql servers are doing this regularly, I can't be the only person with this problem. Can somebody from MySql please let me know that on earth you are doing to my CPU's?? Regards, Ben BTW, who controls InnoDB? Is it Oracle or Sun?

Re: Storing Larger MySQL Backups
I'm curious if anyone has any thoughts on how I can handle a data retention issue I've been facing with a larger dataset. My process, roughtly is run mysqldump against the DB and gzip the output. Then I transfer it off to a different machine for archival onto optical media (yes I know there's a shelf of the media life involved there). This is a secondary backup to the backup I'm doing for system recovery purposes - not the only method of backup, but I don't have access to that storage system as it's provided via the ISP. Recently the file has gotten so big it doesn't fit on a standard DVD-R media any longer. I've considered only backing up key data, but for the archive it's much more convenient to have the entire structure intact in one location - additionally, we occasionally build a test machine from this data so it's integrity is moderately important. Ideally, I'd like to be able to script the compression and slicing right on the server that does the backup, but I realize this may not be possible. I'm looking at using RAR to archive the output file and slice it into smaller segments so I can distribute the data over 2 DVD-R (or multiple CD-R's if so desired.) Does anyone have any feedback on this approach? Without laying out money for a higher capacity DVD/BlueRay drive or tape backup system, what options are you using for data retention? have a look at the split command so that the output goes into more than 1 file eg mysqldump -e -u user -ppassword databasename | split -b 1024m -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

turn a slave back into its own master
hi guys, quick question how do i undo a CHANGE MASTER TO command and make it a master of itself again? thanks
Handling Special Characters
I am having trouble inserting special characters into a table. I am using the MySQL client. I put the following commands into a text file (I'm on WinXP, using Notepad), copy them, and paste them into the MySQL command line client. SET NAMES utf8; CREATE TEMPORARY TABLE `giiexpr_db`.`eo_name_table` ( `eo_name` VARCHAR( 255 ) NOT NULL ) ENGINE = MYISAM CHARACTER SET utf8 COLLATE utf8_general_ci; INSERT INTO eo_name_table (eo_name) VALUES (Associated British Foods Plc (Abf) - Hot Drinks - World); SELECT * FROM eo_name_table; +-+ | eo_name | +-+ | Associated British Foods Plc (Abf) - Hot Drinks - World | +-+ 1 row in set (0.04 sec) That symbol before World is an N-dash, 0x96. This works perfectly. Here's where things go wrong. If instead of pasting these commands into the client, I source the exact same file, I get this: +-+ | eo_name | +-+ | Associated British Foods Plc (Abf) - Hot Drinks | +-+ 1 row in set (0.04 sec) It seems that special characters are treated differently when they are in a sourced file. It isn't just the N-dash, French accented characters cause the same problem. These are all single-byte characters. Just to be sure, I checked the length of the string in the field, and it accurately reflected the difference. That proves, to my satisfaction, that the problem is on the input side. I'm using version 4.1.22 community server on a Linux platform. I'm using version 5.0.45 of the CLI client. Anyone have any ideas? I was trying to avoid having to write a program to do this.

Re: basic style shema question
Hmm. If we're talking pure DB theory, then the whole point is to apply the DRY principle as much as possible. At the point you have multiple copies of the same data, unless your programmers are perfect (and they aren't, I promise), you *will* have stale data. Better to have only one place to update things. Some other questions/thoughts that come to mind: - Will it ever be possible for a company to have more than one contact email address? - Do you /really/ want to store the user's password in your DB? Look towards salts and SHA/MD5 sums. - If you have more than a few people with the same company, are you at all worried about disk space? - Disk contention is often the bottleneck, if your DB can't fit entirely in main memory. Having less places to update means better disk access. - Usage patterns, as you described, are also a concern. Logging in is an issue as is accessing other data. What's the ratio of currently-logging-in-users to other data requests? No need to pull the entire data row if you're not going to use most of the disk pages. - Will you have mainly INSERT queries, mainly SELECT, UPDATE, DELETE, a combination? DB's and engines are better suited to different types of workloads. - Are you worried about integrity of your data? How many foreign key constraints will you want? These all tie in together, and generally beg the question of *your* usage patterns. If this is a project of any import, I can almost guarantee that what you think will happen will not align with what actually happens. With that in mind, having the agility of multiple tables with correct data (read: use foreign key constraints) will likely behoove you. You might want to take a look at some articles on normalization and schema design. Wikipedia is a good starting pace.
