MySql at 100% CPU
Dear MySql, I hope you can help me trace a problem. Every few days one of my 5.0.45 will stick at 100% CPU whilst not doing very much. The server is a replication master and slave, but idle at this time. I am running 100% InnoDB and there is nothing in the error log. It will stay that way for minutes or hours, or until it is restarted. This load cannot be accounted for by the processlist. I need to know why MySql does this. If any person knows how I an identify the problem, please let me know! Thanks!

performances and optimization in multiple join queries
Hello everybody! I have a huge query (something similar to a search engine), full of left joins and my testing server takes several minutes each time to output the recordset. I was looking for some (right) way to optimize the search. there were some solutions proposed around, like split in n simpler queries and then merge the results, or create some temporary tables containing the filtered data to let the main query execute without too many iterations... I was wondering if there was anybody here, to suggest the best approach to this kind of performance issues.

mysqldump - new version = no data?
I've been using mysqldump in a Perl script for a client of mine to do database dumps for several years and until recently it has worked fine. However I noticed that in a recent dump, no data or schema was created. Since I don't know for sure where 'mysqldump' is located on the remote system I use 'whereis' to find it. Then I use the first path I find. Here are the paths containing 'mysql': /usr/bin/mysql /usr/lib/mysql /usr/include/mysql /usr/share/mysql My command string is then similar to this: usr/bin/mysqldump -uusername -ppassword database_name mydatadump.sql Now this command produces this output file: -- MySQL dump 10.10 -- -- Host: localhostDatabase: database_name -- -- -- Server version 5.0.27 /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; /*!40103 SET @OLD_TIME_ZONE=@@TIME_ZONE */; /*!40103 SET TIME_ZONE='+00:00' */; /*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */; /*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */; /*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */; /*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */; Previous outputs had header data: -- MySQL dump 8.23 -- -- Host: localhostDatabase: database_name - -- Server version 3.23.58 So it appears the host has updated the MySQL server, and of course mysqldump is new. Now my script is broken until I patch my code with a new set of parameters. I would not have discovered this unless I had been doing some poking around on the server. This is very frustrating and potentially dangerous, since my client could have done a dump / restore not knowing there wasn't really a dump to work with. Has anyone else had this problem, and hopefully got a working solution? If this is going to keep happening every time the server gets updated then I (and lots of others I assume) will have to find an alternative way to let my client do backups. -- Amer Neely - Web Mechanic w: www.webmechanic.softouch.on.ca/ -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

RE: changed directory name
This is actually a PHP issue and nothing to do with MySQL. You're correct in that since you renamed the directory, the scripts can't find their includes. Ideally, they should be using relative path names and/or setting the include_path php.ini variable to avoid this. The quick however, answer is given to you in the error message i.e. Change line 52 of C:\webserver\xampplite\htdocs\extreme\admin\index.php to be: include(C:/webserver/xampplite/htdocs/extreme/include/language/en/lang.inc .php) (and all the other include, require calls as appropriate) PS: I'd advise against using any upper-case characters in your web folder names (URLs) as this can lead to annoying problems later down the line.

Re: Prepared SQL statements - Faster performance?
I can't speak to the exact internals of MySQL, but in database practice one *generally* uses prepared statements for two reasons: 1. Security 2. Speed If your system is at all exposed to the outside world *and you at all value your data*, your biggest concern should /absolutely/ be security. By using prepared statements, you reduce the number of places to secure by letting the database do your escaping for you (e.g. database developer's know better what to escape than you). It's actually better than that, but that's a simple explanation. If you're not exposed to the Internet at large, and speed is your concern, prepared statements can give a speed improvement, but not always. The reason for the alleged speed improvement is that generally one prepares the statement once and then aggregates the cost of preparation over more than one execution. Juxtapose with reparsing and executing for every set of arguments, where the plans are largely the same: the parsing phase is duplicate work. But preparation is not always a win. Say I have a table of stored materials. Picking the perfect plan is highly dependent on what data I have, and what data I want. Take this query as an example PREPARE( SELECT material FROM stock WHERE mass = ? ); Presumably, just having an index on 'mass' will make things faster, right? That makes an assumption that I have an evenly distributed set of data. What if 5 billion items in my warehouse are 5kg, and 3 items are 10kg? If I plug in 5kg, my indexes are useless, and are in fact a loss to use. If I plug in 10kg, my indexes are a huge gain. Without knowing before hand what data I'll need, the planner will likely make a poor decision in favor of the best general decision. To answer what you can expect from planning: YMMV. I have had code bases improve from 90 minutes to 5 minutes on the same hardware. I have also had code bases show decreased performance by implementing planning.

Yet 'top' and other tools show MySQL using 100% CPU I really need any kind MySQL guru who can give me some advise on how to track down and stop my four MySQL servers doing what ever they doing...

Upcoming Mandatory Changes post-Sun Acquisition
Greetings! Bill Bilano here to chime in on what the Sun acquisition will mean to everyone here! Below you will find a list of changes that may impact how the MySQL Server and Client tools products will be utilized in the future. This list is in no way complete and I believe that additional changes will be announced as I see fit. Now that the big dogs are in the house, it's time to get a few things in line and get our ducks in a row. We need to make sure we don't rock the boat and everyone is carrying their own weight. We don't want any suprises! There are some big changes that are needed in order to compete in this rapidly growing market segment. 1. Now that Sun in large and in charge, you all need to learn up some new rules: HIPPA, SOX, PCI, and GLB. 2. The name of the product is changing to Product SuperNova; no more of this cowboy B.S.! 2. No more of that ISO ANSI SQL junks! Sun is not interestes in that! From now on ALL search queries must be submitsed in accoding with a forthcoming XML DTD! There wont be ANY exceptions! (YES THAT MEANS YOU, MONTY!) 2. The backend must be complete re-writted in 100% pure Java! This is going to be made into a case study in how Java usage can fix the mistakes that bad programmers made! MySLQ seems PERFECT for this! 3. All administor tools need to be redone in SWING! This is the only cross platform widget standard there is and you have to use it. Immediately. 4. Create and Optomize an NFS table storage mechanism! Find a way of doing this. 5. We need something to complete with SQLLite so GET 'ER DONE! LOLLL! 6. Full steam forward on MySQL-FS projet!! this needs to be merged into the primary source trunk... we know that ZFS is balls and Billy goat Gates tried to meet the brokeback demon with YUKON but he couldn't work it. HINT: This is the joker up our hole! 7. Zero tolreance for anybody who gives Theo allowed to access the source tree any more! For any reason! Even if he promises! 8. Be ready to do a presentation on why you need to keep your job with MyQSL after the merger. Have this ready for the next board meeting because they will be interviewing all employees! Some of you will be fired so have a plan for this as it is not MySLQ's problem! Now that I've spelledt it all our for you guys, you can thank me! Just as an FYI: _I do not work for MySQL or Sun_... I have some big Suns 6800s in my server room here at the bank and them is some fast, but these are the changes that I see as absolutely ESSENTIAL to the success of the product in the futuer!!! If SUN follows my lead, and I believe they will becacuse of my mile long list of credentials, then we can look forward to wide acceptence of this fantastic product in the futare! (i am IT director for a huge US bank and as such I demand respect, and i typially get it because of my great ideas and tireless devotuoion to the cfommunity!)

Re: Computerworld reporter would like to hear from you ASAP today, on MySQL,acquisition by Sun...
Todd, I'd be happy to answer all of your questions. See my responses in-line below: What are your impressions of this deal? I think it is fantastic because it means that even more money will be made and this is what Sun's top priority is and represents what they care about, realistically. This is why I use commercial software instead of open-source. Is this good for the MySQL community? Absolutely, Todd. It will help get the errant programmers back on-track with sound software design and solid methodologies. Being able to rely on the sage judgment and wisdom of Sun's proven software developers and technological leadership will only make the community stronger and the products better. Good for MySQL users? Todd, I can't express how much better it will be for end-users! If you take a look at one of my other posts to this very mailing list, you'll see a broad strategy that I've outlined for the future of MySQL. I've put forth a number of proposals including a new MySQL-FS file system, new cross-platform administrative tools, and a renewed focus on the Java language and how it can be used to help MySQL along the road to success. Do you see a downside here? Not yet I don't! Overall, is this a good thing for MySQL and its users or a bad thing? As I've outlined, I think it's a fantastic first-step towards bringing MySQL out of the 20th century and into the 21st. This is nothing but the beginning of a bold new era in the annals of MySQL history. Together, Sun, MySQL, and the community can bring about the change that is needed. Please tell me your thoughts in as much detail as possible. Be sure, please to give me your FULL NAME, Job Title, PHONE NUMBER, e-mail address and what you do for a living -- whether programmer, consultant, etc. My name is Billy B. Bilano.

RE: creating temp file, modifying data and putting into other table
Thanks for the input Jochem. I am testing the code using the MySQL Query Browser 1.1.20 and putting the script in a single Query window over multiple lines. The first line create temporary table Ttable1 (select * from masterlist where ref='ABCDE'); works fine (well I don't get any errors). The problem is that when it processes the second line update Ttable1 set ref='SMI0C001'; it tells me that Ttable1 doesn't exist. I thought that temporary files exist for the session?
