MYSQL :: Slow Running MySQL?

I'm having a problem with a new machine running Mysql version 4.0.18
on the AMD64 version of Mandrake 10.0. The new machine has got 64bit
AMD processor and 2GB of RAM.

Nearly all queries(updates are especially slow) are running 20/30 or
more times slower than on an inferior(32 bit processor, 1.5GB RAM)
machine runnning Mysql 3.23.56 on mandrake 9.0.

As far as I can tell mysql is configured correctly for the power of
the machine. The my.cnf file looks like this: Code:

i am not using mysql but an unknown database system on a unix box - i have no control over the database but have purchased an odbc driver that seems very 'clunky' after using mysql - this is an sql statement question rather than a mysql tech question. if i run this:

SELECT
MK_01_vehicleRecords.registrationnumber, MK_01_VehicleRecords.vehiclenumber
FROM MK_01_VehicleRecords
WHERE (MK_01_VehicleRecords.vehiclenumber = '36176')

I have been running mysql server 4.0.14 standard on a Dual Zeon 2.8GHz machine with 2GB RAM and linux redhat 9 for about two years, then all of a sudden it has started to run at a crawl.

The database contains 26 million rows but 19 million are in a table the is very rarely used but occasionally needs to be accessed reasonably quickly (but performance isn't an issue). Approx 5 million rows are in another table this is used daily. The next biggest table is 444,000 rows.

Is there a likely reason for the sudden slow down, can i do anything about it as it is operationally critical that i fix this quickly.

I am very new to mysql. I am using the sitepoint book 'Build your own Database Driven Website using PHP and MYSQL. I have installed mysql mysql-5.0.41-osx10.3-powerpc. Under preferences/mysql it indicates that the mysql server is running. When I try to access mysql through the terminal window I get a message - command not found. Or no permissions. I can go to the bin directory and list the contents - they seem to be there. I can't get past page 21/22 Post-installation setup tasks. I am also new to using the terminal window. I suspect I have missed something really basic - any suggestions on how I can get up and running would be much appreciated!

I wasn't sure if someone would be able and willing to help me, but I am new to installing MySQL on a Windows 2003 server (actually .. any server), but I am installing it on a Windows 2003 server right now. I also installed a new version of PHP on the same server. Everything looks fine, but when I go to phpinfo.php I don't see anything saying MySQL. (I saw somewhere that if MySQL is installed properly, it should be displayed on the phpinfo.php page.)

I am currently trying to set up and run Cerberus Help Desk, but it isn't finding the MySQL database that I installed.

So, I would really appreciate it if someone could not just help me via email or postings in here, but actually by using Instant Messenger (AOL, Yahoo! or MSN) to walk me through the set up, testing, etc. so I can get things up and running properly.

I was hoping that someone with more experience than I might be willing to help me in this manner.

I went to MS-DOS to start the MySQL application by typing mysqld into the bin directory of where I installed MySQL but once I did typed the command and pressed enter this is all I got :

A moment passed before I am shown the path of bin with no indication of MySQL server started. And also I have installed this as a window service.

I've just downloaded and installed 5.0 on my Pc/ win 98se.
When I run the program MySQL Command Line Client, it appears to run for a second then disappears. I see the program flash open for a second and then it is gone.Complete newb needs some help.

I've been running mysql 4.1 for sometime and using phpMyAdmin (v2.6.2) to administer the databases.

Using php scripts I can also update/insert etc the databases (maintained on my laptop Mac OS X Tiger).

Suddenly, I can't get phpMyAdmin to load in the browser. I've also tried other MySQL GUI tools like CocoaMySQL and Navicat....they won't run either. I downloaded and installed phpMyAdmin 2.6.3-pl1 as well but no improvement.

Why would mysql run but the admin apps not work?

I have used PHP and MySQL for a few years now. Just today I can across an application that had a MySQL database running locally off a CD ROM. I did not know this was posible. When the application runs it starts up the MySQL database without the user even knowing they are running it. It is pretty amazing.

So I want to do the same thing. Is there any documentation on how to run MySQL locally. I would like to know how to build the database and create tables under these curcumstances.

I have installed mysql-3.23.54-win and it all seems to have gone OK .... now i want to run it and setup a database. I dont have an icon on the desktop and there is nothing in Start - Programs ..... start it from DOS prompt via C:> C:mysqlinmysql.exe and i get error 2003 cant connect to MySQL server on localhost <10061>

I really need some help with this. MySQL will not start on boot despite
everything I've done to make sure that it is set to do so.

When I start it as root from a terminal with "/usr/bin/mysqld_safe
--skip-grant-tables &" I show several mysqld procs. and one mysqld_safe,
but I can't connect:

[root@adamsmdk madams]# ps -aux| grep mysql
Warning: bad syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html

When linking with mysql 5.0 library, I can't no longer use gdb to debug
my app anymore. It cores immediately with a bus error. I've also
noticed that the size of the executable is more than doubled compared
with one linked with mysql 4.0

Have a very large database and due to performance requirements it seems that running MySQL in RAMDisk might be a good solution. Access to the database is through PHP. Any suggestions or experiences?

Actually what I want to do is remove 4.1 because I downloaded 5.0 and installed w/o removing the previous version. I now have port 3307 for 5.0. Is this a problem and how can I change it back to 3306 so e.g. when I use Apache/PHP evrything works?

I'm running MySQL on my Mac, and I'm trying to figure out on what port MySQL is running. What can I type into Unix terminal to figure this out? Or can I find out some other way?

i'm trying to set up MySQL with IIS 7.0 on Windows Vista Home Premium. After you install MySQL, there's a check box to launch the config app.

if i leave it checked, the app does not load. if i try to run the app by double-clicking its icon it gives me an error saying, "The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail." I cannot find the application event log, though.

I need to run this sort of querys from shell:

delete from 3dinformatica where preco = " " ;

CREATE TABLE tudotest AS SELECT DISTINCT * FROM 3dinformatica;

DELETE FROM 3dinformatica;

INSERT INTO 3dinformatica (cr_datetime,produto,vendedor,preco,link) SELECT DISTINCT cr_datetime,produto,vendedor,preco,link FROM tudotest;

DROP TABLE tudotest;

i wanted to put the mysql cmd in a file like mysql.sh and run it from crontab.
i have about 100 querys like that i need to run at the same time.

IÂ´m running mysql on a Pentium 166 Mhz with 16 Mb of RAM. Pretty old, right?

I want to know if there is a way to improve performance. I donÂ´t know, something about reducing the number of queries that it will respond or cutting out some features.

how can i test if mysql is running on my machine?

Have a very large database and due to performance requirements it seems
that running MySQL in RAMDisk might be a good solution. Access to the
database is through PHP.

It seems that my computer is running two different mysql versions. When I'm trying to login to the database it refuse my password and giving me access to the test configuration. This is what i get in the event viewer.

Do you already have another mysqld server running on port: 3306 ?
Event id 100.

The problem occur when I changed my password for the database. I have turned off Mysql in local services but i think that that's the original version. When I start the xampp i think it starts the winmysqladmin version (not sure). How do I reconfigure the hole thing and how can I see what's running on my machine.

I actually have another question to. I'm trying to run and open the shell mysqladmin which doesn't work. It's just a flash, which one of them am I supposed to run?? You have several options like mysqladmin, mysql, mysqld, mysqld-nt....etc. I opened the winmyslqadmin which i think wasn't that good.

Can anyone suggest a reliable and inexpensive backup service for mysql? I have about 50 tables, of which I've been doing database backups daily on the server, then downloading the backup every couple days or so. The backup files are starting to get relatively large, and I'd like to find a service to backup to off site.

How do i find out if a MySQL database is running or not?

I had downloaded a few years back mySQL v3.51 installed but never used it. Now I wanted to convert some B-TREE databases to mySQL and did some testing via ODBC to insert 70,000 records: My results:

MS ACCESS: ~60,000 msecs
MYSQL v3.51 ~18,000 msecs

Impressed with the speed, I went ahead and got the latest MySQL v5.1. Uninstalled the older version, I had nothing there to preserve, so I did a simple new install with MySQL v5.1. I noticed the size of the files and BINEXE increasted by 1,000,000%. Ok, Bulky. Not a problem.

I reran the same ODBC test, and now I got:

MYSQL v5.1: ~450,000 msecs or 7.5 freaking MINUTES!

What the hell happen? Nothing was done. I'm knew to MYSQL. I just installed it with all the defaults. I did choose "developer's machine" for the "optimizer wizard"

I can't redistribute MYSQL v3.51 and force it down people's throats! I have to use what they are using already, if already installed. Not even my current system takes 1 minute to add 70,000 records. Why 7.5 minutes? All it is simple inserts/free statements.

I have this one site that slows down all my others because the queries are so massive.

For example one of these queries I use to-do a search by a user's account number. I also get the position he is at on the list, and in order to-do that I need to select ALL the rows.

For example, I filter out the other queries in php.
CODE$num = 1;
$q = mysql_query('SELECT * FROM lists');
while($r = mysql_fetch_assoc($q))
{

   if($r['account']=='accountNum')
   {
         print 'You are at pos. num '.$num.'<br>';
   }
   $num++;
}

I just changed to use MySQL few days ago but it was a bad idea. My server now is running very slowly with the database. I'm using Perl5 and DBD::Mysql in my script. The system is Linux9, Apache2.

I looked at these mysql pid and saw a lot of activities (about 400) while there are more 100 users online at this moment and lots of running under a the same pid number.

I have the long query time set to 15 yet MySQL is still showing results with a query time of 0 in the slow query log.

It says enter time in "seconds" in the MySQL Administrator but did it mean in milliseconds??

mySQL has been running very slowly and I am getting errors. First I did 2 things I raised the ServerLimit number (apache) to allow for more connections, I also raised the max conncetions in my.cnf. I do not know if this took effect? That should have worked. But basically in phpmyadmin i get this error frequently. I am getting more traffic so I think it is that.

MySQL said: Documentation
#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)

I am trying to take address info from 5 different fields in mysql, concatenate them into one string of text and have then run through a POST, like you would in a form, and have them spit out on the other end into the database the Lat and Lon of the address... I can do it manually, but I would like to do it automatically...

I would like to know if I am going at this right...

Psuedo

QUERY=SELECT addressNumber, addressStreet, city, state, zip FROM table
$addressStr=addressNumber + " " + addressStreet + ", " + city + ", " + state

RUN IT THROUGH A POST SOMEHOW??? and call GEOCODER from my manual insert script...

$sql=INSERT INTO table SET lat='$lat', lon='$lon'

I installed from source mysql on Fedora3 and started mysql demon without my.cnf by chance and it was running . I m wondering did it happen with somebody else too?

We have created an instance or schema that contains over 14000 tables. It is a lot of tables. When we attempt to browse the tables in the GUI it literally takes 5 minutes or more for it to come back. Granted when using the Microsoft SQL Server Management Studio it is slow but doesn't take that long. After about a minute or so it gives the list and is kind of slow to scroll.

Can this be fixed by optimizing the database? Is this just too many tables for mySQL to handle?

I am used to use MySQL on Unix, now I have to do some development for MySQL running on Windows machine. The following script works well in Unix but I am unable to run it on Windows. "MY_FLAG" is the one which is causing issue. Due to certain restriction in my framework, I can use the normal batch by supplying the .sql file while opening the mysql connection ( infact i need to run multiple source files) Code:

I uninstalled that and reinstalled that. Then it doesn't work anymore... I check the process of the "Windows Task Manager", but I couldn't find the fimilar mysql-nt.exe...

Do you have any idea how should I fix this problem? Should I reinstall the whole XP system?

I've had mysql on my machine plenty of times with no trouble currently i have SQL Server 2000 Trial running but never both at once. Unfortunately i have to have them both on at the moment.

So before i install and mess everything up, Does anyone here have this setup?

I basically want to get php/mySQL/MSSQL running with IIS

I have downloaded the latest version of mysql administrator 1.0.18. I followed the installation instructions, but when i am unable to run the program. I get an error saying:

./mysql-administrator-bin: relocation error: ./mysql-administrator-bin: undefined symbol: gdk_display_get_type

Do you have any clue about what is happening?

I have been given a some mysql code that I have to run within a website - I am familiar with mysql in terms of insert info and querying a database but I at a loss as to how to make this work.

the mysql code works in mysqladmin, but how do I call it into my php code?

BTW the mysql code creates a new record in the database .......

Also, I need to tweak the code so it runs in a loop for different variables - in php I would run a FOREACH query, how do I do it in mysql?

I have Fedora Linux running on my box. I have installed Apache2, PHP, MySQL. I used YUM to install everything.

yum install httpd

yum install php

yum install mysql-server mysql

yum instal php-mysql

What I want to know is that how can I start playing around with all this cool programs. I want to learn as much about all these awesome programs. I would like to install some kind of control center for MySQL. I heard MyPHPadmin is good. But how do I install it?
Can I do it through yum? Where can I find a good newbie guide?

thanks in advance :-)

I am doing this for the love of MySQL.

How i use mysql in linux without the client and with it?

What software to use to access MySQL running on NetWare from a Windows workstation ?

I can run a script from my shell like this

shell> mysql </path/myscript.sql

But how do I run a script from inside mysql?

I was wondering if any one can help me out, I am literally tearing my
hair out with an availability search I have written.

Previously I was selecting all the records from two databases but
noticed the response time was very slow anything up to 20 secs.

I tried to streamline the search by only selecting the columns I
needed from the tables and created indexes for each of the tables for
the required rows but now the results are executing in around 50 - 60
secs, which is ultimately alot slower.

The SQL query I am using at the moment is this:

SELECT villas.id, villas.resort, villas.beds, villas.owner,
villas.air_con, villas.walk_beach, villas.walk_shop, pricing.id,
pricing.week, pricing.price, pricing.availability FROM villas LEFT
OUTER JOIN pricing ON villas.id = pricing.id WHERE pricing.week =
1073088000 AND pricing.availability = 1 AND villas.beds > 0 AND
pricing.price > 0 AND ( villas.resort = 'cala_dor' OR villas.resort =
'pollenca' ) GROUP BY villas.id ORDER BY villas.owner DESC ,
villas.beds ASC

I am running the Apache web server, MySQL v4, and PHP on an NT4 server.
Apache runs great, but the auction software I am using (Web2035 Auction
software written in PHP) is very, very slow.

Sometimes it takes 20-30 seconds to bring up an auction page from the items
table which has less than 200 records in it.

Can anyone can give me some pointers on where to start looking? (I don't
know if the bottleneck is with MySQL or PHP or what I might need to look at
to enhance the performance of either package.)

It just seems that my system is slow, adding records, etc. I tried to optimize it, saw that there was a my-medium.ini file, read that is was for medium sized system. I replaced it with my.ini (yes I did make a backup, thankfully) and restarted mysql.

Pretty much it hangs. I tried to connect with QueryBrower, did a Select Count(*) and just froze. I admit that I didn't wait for ever, yes I know I Select Count(*) takes a long time but I gave up after waiting 3x as long as I normal did. Also the logs screen froze in administrator.

I am using a Windows 2003 Web Edition Server running IIS and MySQL 4.1. I had to restart the server the other day and it took MySQL almost 2 hours to come back up. I was watching it on my task manager and it went up to approximately 60,000k in 10k increments before I was able to access MySQL.

My CPU usage was hovering around 3% all this time. Everything else came up on the server just fine. This happens every time I have to restart my server. The reason I have to restart my server most of the time, is because MySQL locks up on me.

Is there any settings I can change that would help me here? Any help would be greatly appreciated.

One more thing to add. I am using the default my.ini file. We have almost 100 different databases on the server and have around 20000 tables within all of these databases combined. All of these tables are InnoDB tables.

I have been developing an application in Visual Basic that accesses a MySQL database either on the local machine, or a remote machine. Locally, database connections run smoothly. However, when I try to connect to the remote system (another computer on my local network) some databases take longer to connect than others (sometimes 10 - 20 seconds).

The application usses the myvbql.dll (sorry lost the link, found it through google) wrapper around the libmysql.dll file to perform database actions. The application seems to hang when it tries to actually make the connection to the datatbase. This is only happening on the remote database server, and does not happen on every connection to that server.

I have a sql table with more then 20,000 rows in a table called summary and when I run "select * from summary" it returns a exucutions time of 0.5 seconds in php which is kinda slow if you ask me, now I know that the * type for select isnt the fastest way to fetch data but its the most convenient for me.

Sometimes, when my database server has been slow and building up hundreds of queries, I have the impression that mysql is running 'double' of triple . It's hard to explain, but when I look at mtop (a tool to see what queries are active and what time they take to finish) , I see a lot of queries that seem to hang and that are present more then once. Some of them have unique data in them that can not happen just by refreshing a form. When the peak moment is over, and I check my site, then I sometimes see for example the exact same forum post 3 or 4 times in the same thread. Needless to say, this causes a lot of extra load on my database.

I'm not sure what really happens, but it seems like mysql server is just piling up queries wich it can not process fast enough, and those queries seem to come in several times again. I use seperate webservers, but even if I reboot them all, the extra queries still come in as soon as the webserver is back up and php scripts start to work again. The only way to stop it all, is to restart mysql, but that is something that I can not just do very easily. I rely on several heap tables for my site and they need to be refilled with data from normal tables. So restarting mysql is something I only like to do at night, with very few visitors online.

I hope I'm explaining my problem well enough. And I hope there is a way for me to check what really is going on, and if there is a way to stop mysql from 'running double' ?
