How Do You Stop All The Connections To MySQL?
I don't want any application accessing my databases while performing the recovery operations. In Oracle, you can stop the TNS listener on the server side. What is the equivalent of this in MySQL?

Stop Further Connections To Database
Does anyone know of a way to stop further connections to a database while letting existing ones complete? Does restarting the server allow ALL threads to complete before shutting down?
Can't Stop Mysql
Got mysql started, created root password. Decided to change it and used mysqladmin to try and change. It says access denied. I tried to stop the service, can't do that. I even restarted the computer and it says there is still a connection on localhost:3306 and it can't make changes. I have deleted mysql and completely re-installed. Nothing changes. How can I completely stop the service that it tying up :3306. Is there anyway to see those ports and see what is connected?

Start And Immediate Stop Of MySql
Installed MySQL 4.0.20, Apache 2.0.50 and php 4.3.8 on RHEL AS custom server installation. Did the following, in accordance with online forum/faq suggestions and with Julie C. Meloni's book SAMS Teach Yourself PHP, MysQL and Apache. ln -s mysql... cd mysql scripts/mysql_install_db groupadd mysql useradd -g mysql mysql chown -R root /usr/local/mysql chown -R mysql /usr/local/mysql/data chown -R mysql /usr/local/mysql chown -R root /usr/local/mysql/bin ./ysqld --user=mysql Preceding attempt to start MySql generates the following (slightly paraphrased): Can't change to run as user 'mysql' Please check that user exists. Suggestions?

How To Get Stop Word List In Mysql
I want to use the stop word list of my sql in my program. How can I get this list in sql. Is it stored in some table in database. How can I access it using a query.
Stop Words In Mysql - Ignoring A/an/the
What are the mechanisms to make words like a/an/the in text and varchar character fields ignored when performing SELECT and utilizing ORDER BY in SQL queries? I've done some hunting around into documentation on character sets (but they are geared mainly at character-by-character rules) and saw some reference to string collating and stop words -- but not seen any of this all put together.
How Can I Start And Stop Mysql Server Automatically On Win 98?
I am trying to deploy an application on a Win98 machine (have no choice as this is all the customer has). My application requires the mySQL server to be running, but I cannot work out how to get win98 to automatically start the service on bootup and shut it down when it closes. Any ideas?
# Of Mysql Connections
I was wondering what you guys thought about this. How many mysql connections do you think is to many on a php page?
Mysql Connections
I am currently running MySQL 5.0 on RHE3. I would like to know if someone can tell me how can I get the total number of connections/session to the mysql server via the console or command line?
MySQL Connections
A shared hosting provider allows to setup 10 MySQL databases. The only thing is that each database is forced into having its own username and password, which means a separate connection has got to be made to each database. Is there a way to join tables over the two connections
How Do You Open Mysql To Outside Connections?
I have a DB server and an APP server. I am trying to open MySQL on the DB server so the APP server can connect to it. I did the command: GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PW' WITH GRANT OPTION; However, it still won't connect.
Closing MySQL Connections
Here's a question for you, my hosts have told me that that one my pages, php, was causing their server to reboot because there were too many open connections and that they should be closed. Now, correct me if I am wrong but I thought that the connections were closed after a minute of inactivity. Does this sound right? Could open connections cause their server to reboot a lot, say 3 times in 15 minutes? If so, what can I do about it?
Managing MySQL Connections...
MySQL is currently reaching its limit of connections, and is not responding to new ones. What would prevent against this? Would closing the connection through PHP at the end of every page help with mysqli_close(); Or should I set my max_connections in the my.ini configuration file to a higher number? What other ways can lower the amount of connections?
Best Practices For Php/mysql Connections
I'm working on a data intensive project right now and though I'm able to write code I'm by no means a php or mysql guru, to say I know 'just enough' would be a good statement. So I'd like to ask those who know better... Without going into specifics; users will be searching the database, and/or adding data to the database. I would estimate that there will be far more searches than additions/edits. One of my main concerns is managing the connection to the database for each user. What would the most efficient method be, generally speaking? I would think that I do not want them to establish a connection for each request.
Getting Mysql Error Too Many Connections
I have limited controll of the server settings for MySQL all I can do is create a database, a database user and delete database. I can also use myPhP admin to manage the tables and stuff but as far as controlling the sql server thats all on the hosting company. I recently set up a forum boards (SMF forums its great) all of a sudden one day I went to optimize the tables and whammo the whole board stopped working. When I went to log into plesk and go into My Php admin it keeps giving me this error "Welcome to phpMyAdmin 2.6.0-pl3 phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in config.inc.php and make sure that they correspond to the information given by the administrator of the MySQL server. MySQL said: #1040 - Too many connections What exactly is this error and how do I fix it. I am a noobie with My Sql is this a problem with my hosting companys server or is this an issue I can fix? My hosting support said my database is corrupt (figured that much) but I can't restore untill I can overcome this error..
Several /tmp/mysql.sock Connections
I did a netstat -an and I saw around 80 lines like this: c41cd9d8 stream 0 0 0 c41cd230 0 0 /tmp/mysql.sock Is the server holding too many connections and then cant handle anymore? What can I do to fix this? I am running Mysql 3.23.49 with persistant connections off.
Netstat And 500 MySQL Connections
I was performing some benchmarking on my app and discovered that it opens 400-500 MySQL connections show by the netstat command: tcp 0 0 enssbos:36185 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36184 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36191 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36190 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36189 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36188 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36179 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36177 enssbos:mysql TIME_WAIT tcp 0 0 enssbos:36176 enssbos:mysql TIME_WAIT . Does this look right? Why are there so many tcp network connections for one script? I do use ajax with multiple updates, but I feel as if I am going to run into problems here.

Closing Persistent Connections In Mysql
it might be a stupid question,but I just want to know how can we close persistent connection in mysql (using php). what are the advantages and disadvantages for using persistent connection?
Tracking MySQL Outgoing Connections
I currently have this serious issue where a bunch of mysql connections are being sent from one of my servers to another. I think its a virus or some sort of hole in my scripting but my main server keeps on sending fake logins to my database server. I do not know how this is happening, but IS THERE A WAY for the mysql client (not the database server) to track all of the outgoing connections that are being made?
MySQL Max Connections Remote And Local
My website runs on two servers. One is mean't for PHP and the other is the database MySQL. Whenever a request is made, the PHP attempts to connect to the MySQL via a remove host variable in the mysql_pconnect() function. This works fine, however when it comes down to having lots of connections in the my.cnf file, which one do I edit? max_connections = 1000 Now do I set this in the MySQL only, or do I set it in the PHP server as well?
Remote MySQL Connections, Still Not Working
I've read, and done all the tutorials, forum posts, and comments I could find regarding setting up a mysql server access for remote connections, but I still seem to have problems. I have a LAMP server running behind a closed router connection. A dynamic DNS is masking the connection, and I have the appropriate ports open for HTTP, SSH, VNC, FTP, and I thought MySQL (3306). But for some reason I still cannot get MySQL to connect from a foreign host. The I have port forwarding (3306) to the correct system behind the router, and I can access the server just fine via http/ftp. The MySQL server is happily running PHP MyAdmin with the localhost connection too. I've set a (actually a couple now) user to have the ip access of "%", and granted all permissions to that user, flushed the permissions, even restarted the server. I still can't get the remote connection to work.
Mysql Too Many Connections Performance Issues
I have a website running on a linux/apache/mysql/php server. I receive about 8,000-10,000 visitors a day with about 200,000 to 300,000 page views. The server is a RedHat Linux server running PHP 5.x, MySQL 5.x, Apache 2.x We have been suffering from a number of performance issues. Our hosting company has set our max connections to 100, and we are using persistent connections in PHP. At times the mysqld process takes 100% of the CPU. We have also been suffering from mysql_pconnect(): Too many connections errors. What can I do to fix these issues? When I run a top on the server I see this ...

Remote ODBC Connections To MYSQL
I have a requirement to do some standard table work with existing online survey software (PHP based- using MYSQL). I would like to test the ability to do this work from desktop clients such as access or open office. I have set up an ODBC connection on my machine with appropriate passwords etc. When I run the test in the WinXP ODBC diaglog, it is says that connection is succesfull. However, when I try to use the same DSN in ACCESS or the database component of Open Office, it is that it is unable to make the connection. For example in ACCESS, trying to link tables, the message comes that the ODBC call fails.] In OPEN OFFICE when I do the test connection, I get "ACCESS DENIED" for user... which is the user account and password that I use in the web based projects.
External MySQL Connections Error
I'm trying to connect from my computer to my server. I add my computer to the allowed access hosts. And I'm able to logon correctly. But when I try to select the database I get this error: Access denied for user 'USER'@'%' to database 'DATABASE' Any ideas?
MySQL 4.0 Refusing Local Connections
I am hardly an expert on MySQL. I have limited knowlege on how MySQL 4.0 works. I have used MySQL 4.0 nearly half a dozen times, using these steps, and everything working flawlessly. Download MySQL 4.0 without installer, Extract it to c:mysql. go to c:mysqlin, run winmysqladmin.exe, it will prompt for a username and pass. I type in a fresh combonation. It will start up. I will install the service, and then add the service using the systray icon that appears from winmysqladmin.exe. Now i am capable of logging in with root, set permissions, build databases, etc... etc... For some reason, I cannot figure out why. It is now refusing all local connections. The server is running windows 2000 advanced server. When i install it i do it with the remote desktop connection. simply because the server itself is 1300 miles away.
Sudden Query Stop
i created this script that would loop through a csv file. the file contains about 5000 rows. now when the loop is finished, i looked at the number of rows at the database, its around 360. so i checked, i echoed errors and stuff, and when im sure no errors are left, it puzzles me that whenever the loop finishes, the row count on my database is at 360-380 rows only. i took out the query command out of the loop and echoed the SQL only..its successfull echoed all 5000 possible sql. also..i noticed that my loop actually times out after 30 seconds, resulting in 360-380 rows inserted (i am truncating the table before every loop by the way.) is there any setting in my apache/php/my.ini that i have to configure? if you need to see the code, ill post it on request..
Stop Duplicate Records
How do i stop duplicate records from being inserted into the database. i need to stop duplicates of title and link from being entered .....
Stop Query Ordering
select ... FROM ... WHERE ... IN ('2', '1', '7', '3', '17') I have a query in the same format as above, where I want to select only certain items from from a table based on there ID. The problem I have is that MySQL then orders the results based on this ID (I presume this is because it is the index). What I want to happen is the results to be returned in the same order as the query... is this possible?
Stop Duplicate Records
Sorry if this is extremely newbie of me but how do i stop duplicate records? I have created a small site with php and mysql which allows a user to reserve a parking space online. Im only learning mysql and php so its all done very simply - I have a table with 2 fields - space and daybooked. users can go online and book for example Space number 2 for Wednesday. How would i carry out a check that would stop another user from double booking the same space?
Stop Users From Pressing
I've got a preview button in my app that runs a crystal report. For the first few seconds all is well. You can't click anything on the form and the cursor is an hourglass (as set by my code). But then the form becomes responsive again, the hourglass turns back into a pointer, and the user can select File, Close for example. So for example, the user can open an order, print it, and close the order before the crystal report code finishes printing, causing an error. I've tried this.Enabled = false; This does work but it makes all the controls greyed out. Its not that I want to prevent form events from firing as much as I want to ignore user mouse and keyboard input.
Stop Optimize Table
While trying to shorten my files, I tried optimize table - later I found that I need: mysqlcheck -u root -p[password[ --all-databases --analyze --optimize (thanks to Markus Popp). But it gives this error: mysqlcheck: Got error: 1044: Access denied for user 'root'@'localhost' to database 'information_schema' when executing 'OPTIMIZE TABLE ... ' How can I stop this? The optimise command seem to be in the way (and since I started it, my computer has got pretty slow)
Webserver Leaving Many Unauthened Connections On Mysql
MySQL 4.0.24_Debian-10sarge2-log I have a seperate mysql server and several webservers. One of them recently had an upgrade from debian 3.2 to 4 . Also many things like apache and php got upgraded. This webserver works, but its going slow sometimes. When I check mtop on the mysql server, I mostly see something like this : ID User Host Command State 8606722 unauthen ip:422 Connect login 8606729 unauthen ip:422 Connect login 8606733 unauthen ip:422 Connect login 8606734 unauthen ip:422 Connect login there are usually about 20-40 of those lines, with ip being that of the updated webserver. The only other lines are about 20 waiting 'Delayed, waiting for' lines for delayed inserts (wich is normal), and now and then a real mysql query. All the other webservers do not seem te behave like this, so I'm not sure if this really is a mysql problem. But what I want to know is : what can I do to avoid those hanging connections ? Sometimes there are so many of them, that mysql is running out of connections and is blocking access from other webservers. I can raise this value ofcourse, but that is not a real solution of the core problem.
Mysql Heavy Load On Databases And Connections?
I'm preparing for a lot of potential traffic to a web app. My question is. Is there any restriction on the amount of databases you have on a single mysql installation on a linux server. Could there be any performance issue if for example I had 100,000 databases all being connected to at different times? What is the upper limits of a standard LAMP dedicated server? What i mean is how many simultaneous connection can it handle before it starts to slow down for the users?
Cleaning Up MySQL Connections To Avoid 1040
Well, I'm trying to run PHP $result = mysql_query("SHOW FULL PROCESSLIST"); while ($row=mysql_fetch_array($result)) { $process_id=$row["Id"]; if ($row["Time"] > 200 ) { $sql="KILL $process_id"; mysql_query($sql); } } To clean up my connections, as I'm getting a 1040 error "too many connections". Of course, I can't run this until I can actually connect, unless there is a way around somehow. I don't have any admin rights, I just have a web-based "php my-admin" module to run the db. Every page people access opens a mysql connection, and then it is closed with PHP mysql_close($connection); . Would putting in PHP <?php mysql_close($connection); $NASI_connection = null;?>
MySQL Persistent Connections, Stored Procedures
We have a PHP/MySQL based website. It's our first project where the DB work is being handled my someone else the client hired. They are having us use a lot of stored procedures they created. We've found that in order to run the procedures we have to use a persistent (mysql_pconnect) connection in our PHP scripts. Otherwise, using mysql_connect, ALL the stored procedures generate a mysql error. If we use pconnect they don't. Is this normal to have to use pconnect with stored procedures and if not, what could be the cause? The second problem we are now running into is we are unable to connect to the database because we are exceeding the max connections. Even on our development server which uses a separate database on a separate server with maybe only has 5 or 6 different people that know about the website and use it. The production site is maxed out, getting a too many connections error message. We are still invetigating but I believe they said there were 40 connections to the database. The website is inaccessible because it can't connect. I guess another thing I'm curious about is on a website that is very DB intensive and has maybe a max of 50 simultaneous users at a time, what would a reasonable setting be for max connections on MySQL considering we have to use persistent connections?
MySQL Redhat Slow Responding To Connections
I have installed MySQL 3.53 on two RH7.3 and one RH9.0 boxes. On one of the 7.3 and the 9.0 box, when I try to connect remotely, it takes about 45 seconds to connect, whereas the other 7.3 box connects almost immediately. The fast box has standard install of 7.3 with tomcat added. The 9.0 box is straight RH9.0 standard install. I can't find anything in common between the slow boxes, but not on the fast one.
Shouldn't Mysql_pconnect Force Reuse Of Mysql Connections?
I have this function I call everytime I need to make a query from within my php-scripts: function db_connect ($user, $pwd, $db, $debug = 0) { $link = @mysql_pconnect("localhost", "$user", "$pwd"); if($link && mysql_select_db("$db")) if($debug == 1) { printf("Connection OK!"); } Return ($link); if($debug == 1) { printf("Connection not ok!"); } Return (FALSE); } I thought that making another or a third call to db_connect would reuse the same connection to the database, since I use mysql_pconnect() to connect. But listing the active processes indicates something else: Code:
MySQL Server Initialize Broken Connections
I'm working on program that acts as MySQL client. After successful connection program send queries for a long time. When I stop server mysql_query return error (no surprise). But when I start server my program recieve information again without connection reinitialization. I suppose MySQL server track connections somehow but I didn't find any info about it in documentation. Can somebody point me to docs or explain this behaviour?
How To Prevent Stop Words In A MATCH - AGAINST?
I have a simple search engine for my website, and the MATCH-AGAINST works well when search english words (contained in the `name` and `desc` columns), but when try to search a item-code contained in the `sku` column it seems like mysql handle that code (such as "hp-504") as a stop word and returns zero rows...
4.0.14 Runs CPU Usage Up And Eventually Stop
I am running 4.0.14 on a FreeBSD 4.8-STABLE machine (upgraded to CVS from last week) and I am having a problem. We run a fairly large website using PHP so there is always many connections to the database. On 4.0.12 the cpu usage never shot to over 20% and ran extremely fast. After upgrading to 4.0.14, the cpu goes anywhere between 20-60% and in many situations will not accept any database connections. After browsing the website for a few minutes, I will type mysql on the command line and it will give an error of too many connections. Does anyone know what may be causing this high load from the upgrade? Again the previous versions did not do this and ran very well. I could use 4.0.12 but I wanted to report this in case it continues in future versions.

Create A Stop Word File
I need to change the stop word file used by the MySQL in fulltext seach. The documentation (www.mysql.com/doc/en/Fulltext_Fine-tuning.html) explains how to inform to MySQL the new stop word file through the "ft_stopword_file" variable. But I could not find any reference to the layout of this file, for example, how to separate each stop word in the list? Does someone have any experience on that?
