User Has More Than 'max_user_connections' Active Connections
i am running MySQL server 5 on Windows Server 2003 (x86) and i cannot connect to the server by logging in as any user; i get the following error: "User has more than 'max_user_connections' active connections" I was running a Java program a day ago and thought, that it could have caused a problem by not closing the connections to the db in a right way, so i restarted the MySQL service...

Most Active Users Query
I have a site where users can post in different categories (topics, questions, answers, comments). There is a table for each of those types, and each one has a userId field on it. I'd like to add a "most active users" section that shows the top 10 users with the most entries in topics + questions + answers + comments, but I'm not sure what query to use to get that information.

Shifting Active DB From 1 Server To Another...
I'm after suggestions on the best way to go about shifting an active MySQL database (its for a web stats script) from one server to another along with domain transfer. The problem lies in the time that the shift actually takes place.. i can put a copy of the script and database on the new server so that when the domain transfers, it'll just keep working on the new server... problem here is i dont know when the shift will take place, and will most likely lose some hours/ days of statistics. Maybe if i can make the current script write to a database on the new server using the temporary ip address, and then when the shift takes place make the new script access the local db on the new server (same one as was being accessed before)... is this possible with php/mysql? Is what i'm trying to do do-able, or should i just give up and accept the loss of a few hours/ days of information?

Backing Up Very Active MySQL Database
I'd like to know how some of you with very active MySQL databases (like large vBulletin forums) handle backups? mysqldump raises the server load significantly and slows the site. I think I may lose queries here if they back up while it's trying to do the backup. mysqlhotcopy complained about not being able to open some of the table files. I think it's running into locked files despite its attempts to lock them for itself as there are many queries per second on almost all tables. This is a dual-core Opteron 280 server with 2GB RAM. The database is about 2GB in size right now, and all tables are MyISAM type. Are there any settings I should tweak to get mysqldump or mysqlhotcopy to do the backup without effecting live services, even if the backup takes slightly longer to run?

Converting Field Type In Active Database
When I designed my db in several tables I used unsigned integer fields to hold an integer that each bit was a 'flag'. Now I realize that the set field type does just what I was trying to accomplish. Is it safe to convert the field(s) from uint to set and keep their current values? Obviously all external programming (queries) will have to be adjusted, but it seems to make more sense to use the set type.

Error 1203 User Root Has More Than 'max_user_connections' Active
This error occurs when I atmysqlt to connect to a database via MySQL Administrator or phpMySQL. Everything was working yesterday, when I left work. And this morning, voila...cannot get in.

Too Many Connections Error
I have been getting the following error consistently every few days: Warning: Too many connections in /path/to/connection.php I altered the max_connections in my.cnf to allow for 300 connections. I am not using persistent connections with php. I used to use them but got this too many connections error all the time, so I switched to non-persistent connections, but they don't seem to be getting killed off? I am using php to connect. has anyone else dealt with this issue? Should I perhaps be closing the mysql_connect() after running each query?

Dual Connections
I am developing a PHP script that needs to connect to two different databases in one script. There is one catch, however. One database is on a local computer (laptop). The other database is on a server 1,000 miles away.Is this possible? In case you are wondering why I need this capability: This application allows a user to enter data into a database on their local computer (laptop). With the click of a button, I want to transfer all of the data from the local database to the database on the server. Therefore I need to connect to the local database, loop through each record, copy it into an array. Then I need to connect to the server database, loop through the array, and insert each row into the server database. This must all be in the same script.

'Too Many Connections' Error;
I manage a Linux box that runs a small website and today, my clients got the 'Could not connect: Too many connections' error when they tried to connect to their CMS. Here is what I did: 1. Ran "show full processlist" from a mysql prompt and got the following info: +-----+------+-----------+------+---------+------+-------+-----------------------+ | Id | User | Host | db | Command | Time | State | Info | +-----+------+-----------+------+---------+------+-------+-----------------------+ | 405 | root | localhost | NULL | Query | 0 | NULL | show full processlist | +-----+------+-----------+------+---------+------+-------+-----------------------+ 1 row in set (0.00 sec) In other words, there was only one person logged on, and that was me. I ran this a bunch of times during the day and this was all I ever saw.

What Are Connections And How To Manage Them
I have been using mySQL for several years now, but I currently developing a larger/broader usage website with intense mySQL contents usage. I have been told that mySQL has a so-called connection limit of 50-70. QUESTIONS: 1) What is a connection limit? Or... How do you count 1 connection? 2) How do you properly manage this, to e.g. handle a site that has 1000 simultaneous users logged in to a web site and interacting with the database.

Selecting Across Connections
This is either a very simple answer or a very dumb question, i'm also sure there is alot of documentation on how/why not to do this possibly too much hence my issue with figuring it out. I have a db on-site at locationA. I have a db hosted online at locationB. I want to schedule a query to run regularly (twice daily) that Selects into a table on db at locationB data from tables at locationA, the query needs to be executed at locationA. I.e. SELECT locationA.myonsitedb.tblMyTable.* INTO locationB.myonlinedb.tblMyRemoteTable.* Unfortunately, in my noobness I have no idea where to start here, I have no problem with the queries but I'm completely green to the setup of connections and how to query across these connections or how to setup the scheduling.

Aborted Connections
I get pages error logs with this message - "Got an error reading communication packets". And the aborted clients are easily in hundreds. Here is my set of configurations: I am running Microsoft .Net 2.0 on Windows 2003 Server using IIS 6.0. I am using Mysql 5.0 with Mysql/.Net Connector 1.0. Some of the settings on my.ini - Connection timeout - 180 Wait timeout - 360 Max packet size - 10 M Max connections - 5000 (pretty high, but set to be on a safer side) When a perform a netstat -ao - I have lot many sockets open with TIME_WAIT status. On the MySql Command client - the Aborted clients average around 100's The connection string from ,Net application has pooling=false with no help. The webserver does not have a heavy load and has less than 5 users at any point in time. On the registry settings, I have the max ports > 60000 and the time_wait setting changed to 30. My application is opens a connection, performs a query and closes the connection and this is the fashion followed for all DB operations.

ODBC CONNECTIONS
We are in the process of setting up a database to house some information from our (legacy) ERP. Two questions have arisen: 1. Can we create a direct link to the data source from the db? 2. Currently we are using access as an intermediate connection - the link to the dsn in in access and then we have been exporting the data to the MySQL table. However, this will not let us update the tables it creates because it says the file already exists. If we stay with this method, how do we update the tables on a nightly basis (needs to be an automatic function).

Slow Connections
I am using MyODBC-3.51.11-2-win on Win 2003 OS. I am not able to see all of the connections in the list under the System DSN tab. The connections that show allow the ASP pages to run at an expected rate. However, the ones not showing in the list are running extremely slow. If I attpemt to recreate the connection I am told that the connection already exists and asks if I want to replace the existing connection. Wheter I click yes or no the connections do not show and the pages run slowly. How do I get them to show or resolve the issue. The ASP code is the exact same SQL statements and connection strings as the in previous applications.

Database Connections
i have a general question using the mySQL database. Lets say I have 10 database queries in my application. The 10 queries do not happen one after the other in a short time, so it can be that between one and the next query elapse seconds, or minutes, depending on e.g. user actions of my application. Well, should I open and close a connection for every query or should I open one connection in the beginning of my apllication, then do the ten queries with the same connection and afterwards close the connection again? I think both is possible, but what is 'best practice'? Is it a matter of speed from/to the database

Too Many Connections By A Php File
I have been using a certain php file to connect to a mysql database for some time, but the last time that I checked it for bugs, I got an error message "Warning: mysql_connect(): Too many connections in /home/yonni/public_html/cgi-bin/register.php on line 19. ERROR 3: The connection to the registration database is temporarily unavaliable: Too many connections" I have not changed the coding for the connection to the database since I first wrote it. The code for this part of the script is: $dbh=mysql_connect("localhost", "*my username*", "*my password*") or die ('ERROR 3: The connection to the registration database is temporarily unavaliable: '.mysql_error()); mysql_select_db("yonni_") or die ('ERROR 4: unable to select the correct database'); Why has this error occured, and is there a way of avoiding it? There is noone else viewing the site yet, and I do not know what the problem is. Please help

Too Many Connections (my.cnf Set To 3550)
I'm getting the following error in one of my scripts: Warning: mysql_pconnect(): Too many connections in /home/filexoom/public_html/includes/mysql.class.php on line 5 mySQL: Too many connections on line 5 in /home/filexoom/public_html/includes/mysql.class.php To fix the problem I've raised the max_connections to 3550 (had to raise it gradually), but it is still getting the error on occasion. I don't understand what's going on, I only have about 4000 users in the db. I have restarted httpd, mysql, and even the entire server after editting my.cnf. However I'm still getting the same issue. I'm thinking perhaps the script is not closing the db connections, so there are a bunch that are still open, but should be closed. If so, is there anyway I can kill/flush all the current connections?

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?

Mysql_pconnect() Do Persistent Connections Ever Die
I currently connect to my db with PHP code that uses non-persistent connections. I've read that persistent connections can help performance since a connection to the db will use an existing unused connection. If my system was to go through a busy period whereby I seen an extra 50% or more activity for ten minutes or so, would the extra connections stay alive for ever or is there a time limit of inactivity? Would the unused connections just sleep if they don't die? Is there any negative effect of having these connections waiting around?
