ERROR: Zend_Db_Statement_Exception
Eine Ebene höher

A Google Search shows that under Windows there is dbupgrade.exe
Is there such a tool under Linux too??

Basically i need to take a mysql database that I uploaded to my directory, and load it back into a database. :@
Get Mysql Database From Shell
Apr 14, 2007I have a problem getting mysql to start, so I am planning to setup a new server and move all the mysql databases to a new server.
The problem is I normally get mysql databases when mysql is running by using mysql command lines. Now that I cannot start mysql, I cannot use that method.
Is there a mysql directory that contains all the mysql databases for me to tar it up and untar it on a different? If there is a directory that contains all the mysql databases, do I need to exclude some files/folders so it doesnt conflict with the files/folders on my new mysql server?

Dec 1, 2007I got this weird problem with my VPS which has MySQL 4.1.22 running on it. Everything works fine for sometime and then out of a sudden, it stop recognizing the mysql users and refused to allow my PHP scripts to access the database.
It seems that I needed to restart mySQL server to resolve the issue. Then out of the blues, the same problem occurs.
I am running Cpanel on a VPS and there isn't any overloading as the database access is pretty light on my 512mb VPS.
I contacted my web host about the issue and it seems like all they do is to restart the mySQL. This cannot be a solution as it happens at least once or twice a day depending on how soon I could catch the problem.
All the time this problem occurs, the MYSQL Server is still active and working. I can even access it through PHPMyAdmin but not through the scripts.
I just added an hourly crontab so as to restart the MySQL server as a stop gap.

MySQL With Huge Database
Nov 26, 2007ways to improve the database performance in the situation when I have to modify a large table (several million rows), by e.g. adding a column. Currently this would take several hours which is too slow. The bottleneck is disk I/O. I am considering either partitioning the table over several innodb files on several disks, or going to a RAID-5 or RAID-10, it this will give me better write performance.
The database is 130GB large, and the problem table (which I make period changes to) is the largest table on the server. I cannot have downtime of 3 hours each time I make a change and adding blank fields (to be used later, when a new field is needed) is not an option.
Each time I add a column, the cpu goes into high (80%) io wait state for about 3 hours.
I have a hack which would allow me to split the large table into multiple smaller tables based on some criteria (for example, forumID or such). Here are a couple of things but would like to know which is best, and am open to new ideas. The ideas so far:
1. Split the table into 3 or 5 smaller tables each on it's own disk. The disk IO would then not be so bad, and it might only take 1 hour to perform the table change. But this might not work because the changes to the database (as in adding a column) might be serial, meaning only 1 disk is being written to at a time. (Then again, maybe it will work if I launch 3 different scripts, one to update each table at once).
2. Do RAID 5 or 10, and have 3 or 5 disks. This again might not help at all because of the above issue with MySQL writing serially.
I am using latest MySQL 5.0.45 with InnoDB engine on Debian etch Linux
