MySQL Error
 
HELP!!! Could someone help me please.

I get 4-10 of these errors daily. It got so bad one day that my site crashed. Any advice? I contact my service provider and they told me that it has to do with viewing permissions. I have no idea what to do. Anything would be of help.


Database error in vBulletin :

What is the host service you are using? root or reseller hosting..

host of the web address from the control panel

phpmyadmin , select the repair database tables.

If you enter the following command from the ssh server authority.

Code:
mysqlcheck -u root -p --auto-repair --check --optimize --all-databases
and last.. mysql root password enter...

Code:
service mysql stop
service mysql start
I hope that is helpful :)

Where would I enter that code? What does that do? How often should I repair or optimize the tables? Sorry still new to mysql

I am using 50 of 300 MB is that enough or do I need more disk space?

borbole 05-12-2011 05:05 PM
You have enough disc space. When did this start to happen for the first time? Did you install any mod or did any other modifications to your forum before the error popped up?

fanhockeycoach 05-12-2011 06:42 PM
it started 6 or 7 months ago. i don't think i install or did any other modifications

I got this reply from my host:

The error you are reporting is due to too many active connections to your MySQL database. If you are using mysql_pconnect(), this type of connection never closes. It is a persistent connection that stays open for later use. This can easily cause you to have too many active connections depending on how many people visit the website. We suggest you change it to mysql_connect() instead if you are using this. If you are using mysql_connect(), you may not be closing the database connection at the end of a query, please check that all connections are closed after use.

Does that make sense? Where do I make those changes? Is this something I change on the config.php file?

Boofo 05-14-2011 10:22 PM
What is this set to in your config.php file?

PHP Code:
//    ****** MASTER DATABASE PERSISTENT CONNECTIONS ******
//    This option allows you to turn persistent connections to MySQL on or off.
//    The difference in performance is negligible for all but the largest boards.
//    If you are unsure what this should be, leave it off. (0 = off; 1 = on)
$config['MasterServer']['usepconnect'] = 0; 

fanhockeycoach 05-14-2011 10:36 PM
I have it set at 0

Who is your hosting company?

fanhockeycoach 05-15-2011 05:49 PM
network solutions

Boofo 05-15-2011 06:05 PM
Ask then what you max db connections is set to.

fanhockeycoach 05-17-2011 04:16 PM
thanks for all your help so far. I have two more questions:

1. In the config.php file under master database server name, what is the difference if I put in the servername compared to IP address? Does it change anything if I use one or the other?

2. What is a slave database?

What should it be set too?

It should look like this:

Quote:
// ****** MASTER DATABASE SERVER NAME AND PORT ******
// This is the hostname or IP address and port of the database server.
// If you are unsure of what to put here, leave the default values.
$config['MasterServer']['servername'] = 'localhost';
$config['MasterServer']['port'] = 3306;
You don't have a slave database as that would be on another server, IIRC.

My max_connections are set to 300, but I am on a VPS, and that is probably overkill. Hostagator has their shared accounts set to 25, IIRC.

My max is 10. So what does that mean?

Boofo 05-18-2011 11:01 PM
It means you need to get a new host. If you get very many users on at the same time, you will keep having those kinds of errors.

fanhockeycoach 06-26-2011 12:23 AM
I got 100 VB Database errors yesterday and might site wasn't showing up. I got another 20+ today.

My host shows I am only using 58 of my 300 mb. Would adding another 1000MB help reduce these errors or should I be looking for a new host?
