Re: Cannot complete database transfer
I keep getting 'command not found'. This error indicates that your shell cannot find the mysql file to execute (or that it is not executable for some reason... bad permissions). This can be caused by mysql (client) not being installed or by the client not being on a path that your user can see. more below... Victor Pendleton wrote: Did you install MySQL on the other box?

On the other I created the database using a manager and tried the 'mysql username password database filename.sql' command The problem is, I cannot seem to get the box to see the mysql. I found it in init.d The mysql in init.d is a control script that starts and stops the daemon. It is not the mysql client program and mysql mysqld. vi (or whatever your text editor preference may be) the script and look at it. You can find your bin dir somewhere in this file. Once you find it you can see if mysql is in there. I have root access try su - instead of su if that is what you are using for root access. I keep getting 'command not found'.

Re: Install problems with phpMyAdmin
This may be a bit off-topic for the MySQL List but see below: Gunter Götz wrote: Hello experts, according the desprictions I have installed the phpMyAdmin (2.6.0-pl3) as following: shell su - enter shell mv phpMyAdmin-2.6.0-pl3.tar.tar /usr/sbin/ enter shell cd /usr/sbin/ enter shell tar -zxf phpMyAdmin-2.6.0-pl3.tar.tar enter shell rm phpMyAdmin-2.6.0-pl3.tar.tar shell mv phpMyAdmin-2.6.0-pl3/ phpMyAdmin shell phpMyAdmin/ enter phpmyadmin is a web application. You extracted it to your /usr/sbin directory which is probably not where your web server is looking for files (unless you directed it to do so in your httpd.conf). The default for Apache is in the apache install directory (often /usr/local/apache/html). At the configuration file I did following changes: shell vi config.inc.php $cfg['PmaAbsoluteUri'] = 'http://localhost/phpMyAdmin'; $cfg['Servers'][$i]['auth_type'] = 'http'; $cfg['Servers'][$i]['user'] = ''; After that I startet a browser(Mozilla) at that local server and entered: http://localhost/phpMyAdmin/ But unfortunately it appeared only the message The connection was refused when attempting to contact localhost. Sounds like your web server is either not running or is running on a different port (you would have to alter the std port in httpd.conf) On that server runs a mysql server (V.4.0.22) which is placed in /usr/sbin/mysqld. I`m just a beginner with linux, mysql and phpMyAdmin. Who can give me support? Is there any additional software for PHP necessary? To run phpmyadmin you need: Web Server that supports php (Apache is good, if you get Apache 2.0 use the prefork option with PHP, if you don't know what that is go with the 1.3.x versions for linux)-- www.apache.org MySQL-- www.mysql.com PHP-- www.php.net There are quite a few Linux distro's that can create all of this during install for you if you are unfamiliar with installing software on Linux. hth, Jason McKnight Mgr.

Re: MySQL support for AMD64
I don't have your configuration but I do have 2 servers running with 3ware controllers (800 or so megs in RAID 5 on each). They are stable and performance is good. I don't run MySQL on these however. I also have an AMD64 box running Fedora/AMD64/MySQL and everything is stable. My AMD64 box is not a production box (sadly I usually buy DELL for servers and they may never offer an Opteron solution). There are others on the list who can tell you what you need to know about running high end MySQL installs but I can tell you RAID5 is probably going to limit your performance. Also you might want to calculate the possible size of indeces as that can affect how much ram you really need. hth, Jason McKnight Mgr.

Re: Downsides of MySQL?
To the original poster: Is this a loaded question just to see what kind of response you might get? The application that requires a database server was not mentioned as far as I can tell, but that will influence your decision on what backend to choose. If you need every feature set under the sun go get Oracle. It is really nice. It is also really expensive and you need some massive hardware to run it (to run it well anyway). And dont for get to hire that Oracle DBA while your at it for an additional $60k (US) per year. If you need a fast reliable database server MySQL will do nicely for most applications. I'll bet there is NO WAY that you can even pay for access to the actual developers of the commercial database systems. You get that access right here in this list. You can also pay them (yes everybody needs some type of income) for different levels of support. check it out.

We've used it as our database in the past and we plan on using it in the future as possible. With that said, I confess I don't have as intimate a knowledge of mySQL to address some of the things in the email that was sent to me. I'd like to hear what some of you have to say/think about this. I know some of the things said below aren't entirely correct, but I'm not 100% sure about some of the others. --Begin Quote-- MySQL - as I said at our meeting, we would not be comfortable with this as an enterprise strength solution. MySQL is unsupported freeware and lacks enterprise management functionality. Do these people even know what they mean by 'enterprise management functionality', or did they just crib from an Oracle brochure? DO they have any specifics about what they require? It has a small limited feature set compared to ORACLE, DB/2 and is lacking the functionality to support data replication and has little capability for generating management info. No surprise that these folks haven't been following MySQL development for quite a while, and probably don't know about its replication features. I haven't used 'em myself, though, so I can't vouch for their robustness. As far as the feature set manageability, it's true - there's a lotta things MySQL made a conscious decision to leave out (unions, views, triggers, stored procedures, subselects [i know, coming soon], foreign key support, etc.) in favor of speed/small memory footprint. And you have to go to third-parties for reverse-engineering/diagramming tools. If your application requires such, then maybe MySQL _isn't_ the right solution; however - depending on your app - Oracle/DB2/whatever might be sheer overkill. Administrative overhead for systems like those might far outweigh any advantages they have for you. There are question marks around the scalability of the product, I'm not sure of the locking algorithms used (whether row level or record level) - the It depends on table type; AFAIK, it can be table (ISAM/MyISAM), page-level (BDB), or row-level (InnoDB). See: http://www.mysql.com/doc/L/o/Locking_methods.html http://www.mysql.com/doc/T/a/Table_locking.html http://www.mysql.com/doc/I/n/InnoDB_Next-key_locking.html You've got a choice! This used to be considered a good thing... fact that it is not generally used in multi-user solutions is a good enough indication that this is not accepted database technology for industrial-strength multi-user systems. The fact that it is unsupported freeware would mean that an end user would potentially be held to ransom by a DBA with specific knowledge. This kinda of statement is beginning to REALLY rile me when I hear it. Even if you discount the fact that this mailing list provides better support than the majority of PAID support programs, if you want to, the MySQL folks would be more than happy to take a large amount of your $$$ to provide excellent support: http://www.mysql.com/support/arrangements/types.html - this can include customizing MySQL for you! There are also individual consultants firms that will support you as well. How anyone could actually back up a claim of MySQL being 'unsupported' is beyond me. The mySQL security model is also not sufficiently developed for any system that involves money. I dunno, with some combination of encrypted fields, database server behind a firewall, SSH-tunnelled communication and good DB/system administration, you'd have a plenty secure
