Re: Fw: Server-Client
I could not understand what you try to do. But generally mysql runs on a server machine and the clients connect to it. Every client program you write can connect to mysql server seperately. If you want and need you can also write a server program too. But you have to be more clear about your problems and purpose to get a good answer.

MySQL tables performance question
Hello, I have a table where misc data are stored. Right now this table has about 30 columns, but for sure it will be more in the near future. So I wonder how the big number (50-100) of table's columns affect for MySQL DB performance. Maybe it's better to create more tables rather than more table's columns ??

Do you mean that you want to run two servers as services, and you want to use a single my.cnf file to store the options for them? If so, then you use the approach of specifying a service name after the --install option, and using an option group corresponding to the service name in the option file. Each server will have a different service name, so each server also reads a distinct option group name in the option file. If that's not what you want to do, please clarify. Thanks.

I'm sorry, I'm very new at this. I only downloaded the live version last week. Where do I find the setting you are referring to? By attempt to run the servers, perhaps this is a correct answer to your question: I am only using this for learning purposes. I am hoping to attain new skills and thought that SQL was a good place to start (since I believe it to be the base for many database languages (DBIV (or whatever version they're up to today, Oracle, Sybase, Peoplesoft, etc.) and perhaps if I lose my job this will broaden my choices in looking for a new position/career.

The grants will be only checked. STORING In the backup directory there will be stored the grants. It will keep one week of data like this: mon_grants.sql tue_grants.sql ... CHECK DOMAIN This is a feature not related to dumping the database, but to check the domain of the grants. The way to do it is like this: $ dump_grants --host=SERVERNAME --check-domain=.My.Domain REVOKE USAGE ON big.* FROM 'annmarie'@'%'; REVOKE USAGE ON *.* FROM 'root'@'horta'; The standard error will report the revokes suggested. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Database Admin
Hi, I just installed MySQL. Does anybody know where to manage the databases, create, edit and delete tables? Thanks.
**Checking For Modified Rows**
Hi. I need to replicate data (approx. 10,000 records) from a mySQL database into a different (non mySQl) database automatically on a regular basis. I have no control over the mySQL server (apart from allowing ODBC access) so I cannot modify any tables or enable replication etc... My initial thoughts on how to do this are: 1. Execute a query similar to the following to retrieve a list of rows and a unique checksum: SELECT id, md5(id + _ + name + _ + path + _ + comments) from mytable 2. Lookup each id in my local database a) If it doesn't exist add the id and checksum to my local database and add the record into my actions database as a record to replicate. b) If it exists and the checksums are different update my local database and add the record into my actions database as a record to replicate. REPEAT step 2 for all records At this point the actions database would contain a list of all records which have been inserted or modified. The last step would be to determine which records have been deleted. My thoughts where to mark each record in my local database when a match occurred. Any records in my local database which were not marked as matched would be added to the actions database as records to delete and then deleted from my local database. Any thoughts / feedback on this would be appreciated. Cheers. Kev. E-MAIL DISCLAIMER: The information in this email is confidential and may be legally privileged.

Didn't see a mention of a fix for that problem in the 4.0.14-changelog, will it still fix it? What version of glibc is being used on that system? I noticed that you use the Max binary, which is dynamically linked - so it will use the locally installed libc.so. Is there any special reason for using Max? Or could you try to use our statically linked Standard binary instead? The problem above looks very similar to the problems we had when we linked against glibc 2.2.3 instead of 2.2.5: under high load, a mysqld thread starts eating up all CPU resources on an SMP system. Unfortunately we never found the reason for that - it did not seem to happen when using glibc 2.2.5...

Re: Database Admin
there must be a binary called 'mysql' ('mysql.exe' on windows).
call it, best from the computer where you have installed mysql on:
mysql -uroot
(if it's not in the PATH:
/usr/local/mysql/bin/mysql (i think)
or
c:\programme\mysql\bin\mysql.exe)
now you can enter SQL commands like
CREATE DATABASE...
CREATE TABLE...
INSERT INTO...
SELECT...
if you're not already familiar with these SQL commands, you should look them up in the
mysql manual.

Re: problem with mysql-crashes
Hi Lenz, thanks a lot for your reply! Is that a self-compiled binary or one of ours? It are the MySQL-4.0.13-MAX-RPMs from your site. Not very helpful. Does this occur under high load only? Yeah I know, otherwise I would have tried to generate a reproducible testcase with a given query or such. Any way to have valid pointers there? Nope, the load on that system is mostly around 0.5 with peaks up to 1.5, not something I would call a high load for a dual-system. Also the crashes are at many different times (even in the deep night) so I don't think its related to load :-(. What version of glibc is this system running on? Is it 2.2.3 by chance? Nope, sorry. Its glibc-2.2.4-32. What version of glibc is being used on that system? I noticed that you use the Max binary, which is dynamically linked - so it will use the locally installed libc.so. Is there any special reason for using Max? Or could you try to use our statically linked Standard binary instead? Yeah I could try that instead, maybe I should try with 4.0.13 to see if its a problem of that version. Or should I better try 4.0.14 already? I was hosting a couple of bdb-tables for some time, but no longer now. Currently only myisam and innodb-tables so I could try the standard-built too. The problem above looks very similar to the problems we had when we linked against glibc 2.2.3 instead of 2.2.5: under high load, a mysqld thread starts eating up all CPU resources on an SMP system. Unfortunately we never found the reason for that - it did not seem to happen when using glibc 2.2.5... Hmm, maybe 2.2.4 has the same problem? The problem is that the init-process is taking all the cpu, didn't see a mysql-process doing the same before.

Re: MySQL tables performance question
If you are going to be needing to add columns and/or tables, you should probably rethink your data model. I'm not sure what data you are tracking, but perhaps you can consolidate it a bit more. Make your columns into rows with a row type field. A simple example would be tracking phone numbers. Instead of having separate columns for home, work, and mobile, break it out into another table so you can have unlimited phone numbers. Have a descriptor field to indicate what type of phone number it is. You can then add other phone type with ease, like beeper, fax, car, etc. This also has the added advantage of being able to search on all phone numbers in one query, yet also being able to search on just home phones.

Is it possible to protect MySQL database on a Win2k laptop?
I want to put a MySQL 4.1 database on a Win2k laptop but the problem is it contains confidential client information. It has to be Window because applications accessing the database are written in Windows. The problem is laptops do get stolen quite often, even when running on someone's unattended desk. Most security chains can be cut with a small pair of bolt cutters. I have to convince my boss that if the laptop disappears it won't put the company out of business, and me out of a job.g Is it possible to secure the MySQL database on the laptop so if it does get stolen, the information is safe? The password security of Win2k can be easily bypassed by hacking tools so I can't rely on the security of the OS. I could encrypt some of the columns but how does this affect the indexes? I need to use select custname, col2, col3 from table where custname like 'smith% order by custname'. How would encrypting individual columns affect the use of indexes and sort orders? Are the indexes bypassed? There would be millions of rows of data in the table so I still need to use indexes on these encrypted columns both for searching and for sorting. Does anyone have any advice on how to proceed? TIA. Mike -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Re: How do I show column names in php?
you want to show the column names of WHAT?
if you want to get those of a previous SELECT..., there's a special function for that.
here's some code from my mysql admin module:
$fields = array();
while ($meta = mysql_fetch_field($result))
{
array_push($fields, $meta-name);
}
if you want to get the columns of a table in general, you may either use SHOW TABLE
STATUS... or DESCRIBE...
you can test both in the mysql console and see what they return and how you need to
interpret the result.

Selecting Date Time field, difference in minutes
Hello all, I wonder if is there any way to select from a table all the records which has a Date Field that is at least five minutes old? In other words, I have a table with a date field and I need to select all the records that are older than five minutes, has their date field updated before five minutes. Usually I do it with days by using the to_days() function and comparing the date to now: (to_dayss(now()) - to_days(somedate)). I wonder if I could do the same with minutes.

RE: Can run two versions of MySQL in Windows 2000?
SETUP Windows 2000, Version 5.0 (build 2195, Service Pack 2) (In case it matters, I have about 20 GB available on my 40GB hard drive and 192MB of RAM) SETTINGS Prior to attempting to put on the second server, I wasn't using any options, which was logging me in as [EMAIL PROTECTED] (or more likely [EMAIL PROTECTED]), later I invoked mysql as follows: mysql -h localhost -u root to log in as the root. If you see my treads I was having problems with building temporary tables and was advised to set up a root user, turned out one was set up with the installation so I began using it.). When I started attempting to set up the multiple versions, Victoria Reznichenko directed me to the user manual and was attempting to set it up that way. I shut down the original mysql server and installed the mysql in the 4.1 Alpha folder group with the option mysqld-nt --install mysqld2 which was referenced per the manual in a file called my.cnf as follows: # options for mysqld2 service [mysqld2] basedir = C:/mysql-4.0.14 port = 3308 enable-named-pipe socket = mypipe2 It installed with no errors. Then it instructed I startup the servers as follows: NET START mysql NET START mysqld2 when I did that I got the response: The MySQL service started succesfully. and The mysqld2 service started succesfully. respectively. But when I attempt to invoke MySQL the response is: ERROR 2003: Can't connect to MySQL server on 'localhost' (10061) (BTW. When I came in today I found out that I could no longer connect to 4.1.0 either. When I left last night, I could connect to 4.1.0, but could no longer connect to 4.0.13. According to windows explorer the database files are still there, but for some reason mySQL can no longer point to them.) How I'm running the servers: they are services in Windows. Though I had nothing to do with that. The setup/install utility handled that for 4.0.13. Do I have to give them a unique name for 4.1.0 so Windows can distinguish 4.1 from 4.0? Better detail? Thanks for not giving up on me!

mysql stops processing
Hi, Has anyone ever had any problems with MySQL w/ all InnoDB tables just stop processing queries? There doesn't seem to be any pattern to it, it happens at times of relatively high load (load avg of 4 on a dual proc) but the CPUs still have plenty of idle time, and the disks aren't maxing out. It doesn't happen everytime there is a high load either. The box just stops processing every query, and we quickly hit the max connection limit. The only solution we've found is to shutdown mysql and restart it -- at which point it works fine for a couple days. We are running mysql 3.23.56 w/ redhat 7.3 and 2.4.20 kernel.

If you see my treads I was having problems with building temporary tables and was advised to set up a root user, turned out one was set up with the installation so I began using it.). When I started attempting to set up the multiple versions, Victoria Reznichenko directed me to the user manual and was attempting to set it up that way. I shut down the original mysql server and installed the mysql in the 4.1 Alpha folder group with the option mysqld-nt --install mysqld2 which was referenced per the manual in a file called my.cnf as follows: # options for mysqld2 service [mysqld2] basedir = C:/mysql-4.0.14 port = 3308 enable-named-pipe socket = mypipe2 Okay. You don't have any [mysqld] group for the other server, I take it? But that configuration is odd. It appears to apply to a 4.0.14 installation, yet you state that you're using it for your 4.1 installation. What installation directories are you now using for your two MySQL versions? It installed with no errors. Then it instructed I startup the servers as follows: NET START mysql NET START mysqld2 when I did that I got the response: The MySQL service started succesfully. and The mysqld2 service started succesfully. respectively. Okay, that looks good. When you open the Services Manager, I assume it shows lines for services named MySQL and mysqld2 and that they both have a status showing them to be running? But when I attempt to invoke MySQL the response is: ERROR 2003: Can't connect to MySQL server on 'localhost' (10061) Okay. What was the command you used here? What happens if you use this command: mysql -h localhost -P 3308 or this one: mysql -h . -S mypipe2 (BTW. When I came in today I found out that I could no longer connect to 4.1.0 either. When I left last night, I could connect to 4.1.0, but could no longer connect to 4.0.13. According to windows explorer the database files are still there, but for some reason mySQL can no longer point to them.) How I'm running the servers: they are services in Windows. Though I had nothing to do with that. The setup/install utility handled that for 4.0.13. Do I have to give them a unique name for 4.1.0 so Windows can distinguish 4.1 from 4.0? Yes. The Services Manager will show what the service names are. You may want to shut them down, remove them, and then start over. It may be that the presence of existing services is what's messing things up. To stop the services (assuming service names of svc-name-1 and svc-name-2): net stop svc-name-1 net stop svc-name-2 To remove them: mysqld --remove svc-name-1 mysqld --remove svc-name-2 Then start from the beginning, using the mysqld --install instructions in the manual.

RE: mysql stops processing
Hi, I don't know what type of applications are using your database but if I had to guess at the problem, I would guess that you have a very slow query which runs every now and again that is locking up certain tables/records causing all the other queries to queue up and eventually running out of connections on the DB. To find out if this is the case, when your server gets into this state run a mysqladmin -v pro and see if all the queries are waiting for a lock to be freed up.

Is it necessary to compress tables?
Does MySQL automatically handle deleted row cleanup, or is it necessary to periodically do this manually for tables with a lot of deletions? If it's manual, what are the SQL commands to do this? Also, what happens when changes are made to a field definition? From, say, int to smallint, or tinyint to int, or varchar(255) to varchar(10)? Do temporary tables get created and the data copied over, or does unused space end up in the data files, to be collected later?

error loading mod_auth_mysql
Hi All, I am running mysql-3.23.52 on OS X (10.2.6) and I'd like to install the mod_auth_mysql module for a job I'm working on that used it under a different platform. I compiled the module using: apxs -c -D APACHE1 -L/usr/local/mysql/lib/ -I/usr/include/mysql/ -lmysqlclient -lm -lz mod_auth_mysql.c and installed it: sudo apxs -i mod_auth_mysql.so both of which seemed to go fine. In the httpd.conf file I have put the two lines: LoadModule mysql_auth_module libexec/httpd/mod_auth_mysql.so AddModule mod_auth_mysql.c but when I try to do a graceful restart of apache I get the following response: % sudo apachectl graceful /usr/sbin/apachectl graceful: configuration broken, ignoring restart /usr/sbin/apachectl graceful: (run 'apachectl configtest' for details) % sudo apachectl configtest Syntax error on line 241 of /etc/httpd/httpd.conf: Cannot load /usr/libexec/httpd/libphp4.so into server: (reason unknown) Is there a particular order that this had to go in the httpd.conf file? I can't understand why it is complaining about libphp4. What do you think I'm doing that I should be doing differently? Thanks very much.

UGHH HELP!! I need to write a sql statement that will take the data from my table and use it as column headers. For example, If I have a field named GoLiveDate and a field called Qty and a field called Cars: Cars | Qty | GoLiveDate == CarA | 5 | 7/21/2003 CarA | 10| 7/28/2003 CarA | 14| 8/1/2003 CarB | 2 | 7/21/2003 CarB | 3| 7/28/2003 CarB | 4| 8/1/2003 CarC | 7 | 7/21/2003 CarC | 19| 8/28/2003 CarC | 44| 9/1/2003 The results should be CarsJulyAugustSeptember == CarA15140 CarB540 CarC71944 Any help that you could give or point me to where I can find a solution would help.

Re: mysql stops processing
Unfortunately, we haven't been able to connect to the database because of the maxed out connections. This happens so fast that the maxed out connections is usually the first sign. I've been hesitant to start the monitor, since this has only been happening once every couple days. It's been becoming more frequent, so I'll try turning them on and see if we get lucky. Top isn't showing that our CPU usage is that high. Last time we saw this, it was around 50% on both procs. Also, we are flushing logs every 5 minutes (this has caused problems in the past).

RE: Re-attaching DB to mysql
And from the MySQL docs: --clip MySQL Version 3.23 supports tables of the new MyISAM type and the old ISAM type. You don't have to convert your old tables to use these with Version 3.23. By default, all new tables will be created with type MyISAM (unless you start mysqld with the --default-table-type=isam option). You can convert an ISAM table to MyISAM format with ALTER TABLE table_name TYPE=MyISAM or the Perl script mysql_convert_table_format. --/clip--- You could install this halfway house version or just get hold of the perl scripts and run the mysql_convert_table_format script You've got me interested now - I should be doing real work instead... :) Andrew -Original Message- From: Andrew Braithwaite Sent: Wednesday 23 July 2003 20:59 To: 'Henrik Schmiediche'; 'Mysql' Subject: RE: Re-attaching DB to mysql Hi, If that backup uses the old .ISD .ISM architecture then I would install an old version of MySQL, copy these files into the data dir of that installation and mysqldump them to a file ready for import into your new MySQL v4 install.

large mysql/innodb databases
I was wondering if anyone had any experience with setting up large and fairly high performance databases. We are looking at setting up databases with each machine having somewhere between 500 gigs and 2 terabytes along with a slave box and we'd like to backup everything to tape at a minimum of once a week, but if possible, daily. We're also looking at central storage solutions. However, we're hesitant because that will result in a (very expensive) single point of failure. Of course, we could buy 2, but they are fairly expensive. Has anyone had any experience with setups like this? What kind of backup solutions did you use? We aren't too concerned about the CPU usage as our databases tend to be i/o bound. -- Joe Shear [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

RE: Re-attaching DB to mysql
The mysqldump you use doesn't include the create databease so you'll need to create the henrik DB on the new install. If you keep running it over and over, it will keep inserting the same records over and over again and you'll end up with duplicates. The thing to do is start with an empty db (call it whatever you like) and run the restore just once. This should give you a nice clean backup restore to then do whatever you want with...

This happens so fast that the maxed out connections is usually the first sign. I've been hesitant to start the monitor, since this has only been happening once every couple days. It's been becoming more frequent, so I'll try turning them on and see if we get lucky. Top isn't showing that our CPU usage is that high. Last time we saw this, it was around 50% on both procs. Also, we are flushing logs every 5 minutes (this has caused problems in the past).

Also, no queries are moving forward, no inserts, updates, or selects, even the ones on tables that are only a mixture of inserts and selects. what do SHOW PROCESSLIST and SHOW INNODB STATUS print in this situation? Or is it so that you cannot run them because of maxed out connections? You could write script to run them every 5 seconds so that we could see what is happening. Also, if you do CREATE TABLE innodb_monitor(a INT) TYPE=InnoDB; then mysqld will print the output of SHOW INNODB STATUS to the .err file every 15 seconds. What is the CPU usage from 'top' during the hang? 4.0.14 has better diagnostics than 3.23.56. An upgrade might help, but let us wait a couple of days first. joe Regards, Heikki On Wed, 2003-07-23 at 12:02, Andrew Braithwaite wrote: Hi, I don't know what type of applications are using your database but if I had to guess at the problem, I would guess that you have a very slow query which runs every now and again that is locking up certain tables/records causing all the other queries to queue up and eventually running out of connections on the DB. To find out if this is the case, when your server gets into this state run a mysqladmin -v pro and see if all the queries are waiting for a lock to be freed up.

There doesn't seem to be any pattern to it, it happens at times of relatively high load (load avg of 4 on a dual proc) but the CPUs still have plenty of idle time, and the disks aren't maxing out. It doesn't happen everytime there is a high load either. The box just stops processing every query, and we quickly hit the max connection limit. The only solution we've found is to shutdown mysql and restart it -- at which point it works fine for a couple days. We are running mysql 3.23.56 w/ redhat 7.3 and 2.4.20 kernel. Anybody have any suggestions? thanks, joe -- Joe Shear [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- Joe Shear [EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Is mysqld taking that much though it is not processing anything? I think its all mysqld -- even when it's not going anything. Could it be thrashing on something? We don't have our max connections set that high (100). When we were using 3.23.52, we had really bad problems with a similar problem but the CPU usage would hit 100%. When we upgraded, the problem went away for a month. The 'thread thrashing' problem of 2002 caused CPU usage to increase by a factor of 100, but it did not stop processing completely. Anyway, we need the diagnostic outputs to conclude anything further.

RE: large mysql/innodb databases
Hi, We have similar numbers here. A couple of questions: - are they logfiles that could be rolled over on a daily basis or are they constantly updated huge tables? - is the type of backup you want incremental or a daily/weekly snapshot one? - do you have a requirement for the speed of restore needed in the case of disaster recovery? - is the replicated slave allowed to stop replicating whilst the backup is being performed? Let me know and I think I'll be able to help :) Cheers, Andrew -Original Message- From: Joe Shear [mailto:[EMAIL PROTECTED] Sent: Wednesday 23 July 2003 21:08 To: [EMAIL PROTECTED] Subject: large mysql/innodb databases I was wondering if anyone had any experience with setting up large and fairly high performance databases.

Master/Master Asynchronous replication
Currently we have a web based application that is mostly reads (4:1 r/w). It is using a single MySQL database server. Is there any way to have two database servers in a master/master configuration such that writes to either database server are replicated to eachother. Basically even though we have a 4:1 ration of read/write the writes happen often enought that when the database goes down the app stops working. I know how to get this working in Oracle (insert big laugh here) but Oracle is cost prohibitive. Any pointers? Any suggestions? If this is available in the latest version that would be great.

RE: large mysql/innodb databases
The data is constantly updated. There are 3 or 4 huge tables, and several smaller tables. We would love to have an incremental solution that is *guaranteed* to be correct, but we haven't found a way to do that, so what we've been thing is we'd do a complete snapshot once a week, and do incremental backups of one form or another every day. The replicated slave is allowed to stop replicating during backup. There is no absolute requirement on the time needed to restore. We'd like most disaster recovery to go fairly quickly, but we realize that on our budget, that a major disaster could cause us fairly significant downtime.
