For 5.0 or 5.1 you should really use the most recent versions. 5.1.22 is beta software, the first stable (GA) release was 5.1.30.

Re: Performance issue old server witn mysql 4 vs new server with mysql 5 and old server WINS!
Yup, I'm doing clean tests,lshutdown, and reload mysql each test. The raid setup is similar, Faster is raid1 with 10k harddisk, slower is raid 10 with 15k. Metrics show Old raid Secuecial writting 1G: 533 mb/s (using dd if=/dev/zero of=1G bs=1024 count=102400) Secuencial reading 1G: 500 mb/s New raid Writting: 500 mb/s Reading 800 mb/s Average...

Mysql 4 and or Partitions.
Ok... I solved my mistery of the slow 22G table rebuild the kernel to support memory and now things are working. But still quite slow. I do sum() operations over the 22G table. I'm using the latest version of mysql 4... (I WILL migrate soon, I promise), one thing I have notice, is that operations over that 22G table, seasuring the I/O with iostat never surpass the 23mb/s for reading... even if I test the IO of the array, it can easily give me 300mb/s for reads... and like 150 for random reads... first of all, is there any way to squeeze more speed out from mysql 4? No... I imagined that... So, my next step is migate to a newer version of mysql ( YEY ^_^ )... I have read a few about partitions. The specific query I'm making is a query which do a sum filtered over a date field. What would be the best approach to partition this table? Can I mix innodb with partioned tables and still have acid compliance? The split in several partitions creates more lecture threads or how parelelization over partitions works? And last, does mysql 4 support partitions? XD tia.

If this sample is indicative of the quality of the rest of PerlDesk, I'd seriously reconsider allowing it anywhere near my servers until a full review of the code was performed. Any help on how to fix this would be appreciated, I'd recommend that you either contact the vendor for support or forgo upgrading mysql. I assume that the software was tested with mysql 4 so you probably should continue to use that until you get a version of the software that supports mysql 5. You might fix this one problem, but who knows what other incompatibilities are lurking in the code (and will bite you at the worst possible time) -r -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

DBI does not get involved with the validation of the statement; it leaves that to the database driver (DBD). Not getting any feedback until execute might have been true for earlier version of DBD::mysql because they did not support server-side prepared statements (BTA, neither did mysql itself...). These days you should get feedback when preparing the statement (assuming your server supports it and it is enabled in the driver). -r -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Yes -- sorry for being so general. You can use the binlogs for a)
replication b) replaying changes since your last backup so you get
point-in-time recovery. If you have no replication slaves, just delete
everything older than your latest backup. You can just use 'rm'. If
you use PURGE MASTER LOGS BEFORE, it's a bit easier than cron because
you can do it across all platforms easily. On UNIX of course, you'd use
something like
find /var/lib/mysql/data -name *.bin -mtime +7 -exec rm {} \
(My find syntax is guaranteed to be wrong there... don't run that as I
typed it).
But if you do it via SQL, you don't have to mess with this.

So, I take it since I do not have a slave at all, I could safely just
disable this feature altogether?
If I do not need point in time recovery, and the once every 12 hour dump I
do across all databases is ok with me, I suppose I can just disable said
feature? Heck, some of these boogers are a GB each :-)

MySQL 4 vs 5 - threading model change?? Config Problem?
When I ran version 4, mysql would start as many mysqld process as it needed. This would vary depending upon how busy it was. As a lay perosn I will refer to this as the threading model. I have upgraded to version 5 and notice that no matter what it only runs 1 mysqld. Everything seems to work fine, but I want to make sure that mysqld is taking advantage of my multiple processors. Has the htreading model changed and now MYSQL will only run one mysqld OR have I missed something and need to enable it? Am I getting the best bang for my buck by haveing just one mysqld running?

I know your problem is now solved, but a quick tip for users of BBEdit when searching for 'rogue' characters: Sometimes you can't see them at all in the normal display, but if you go to the page preferences menu - the third little square from the left inside the message window - and select Show Invisibles, this can reveal various oddities. You may find, eg, control characters appearing as inverted red ?s, or non-breaking spaces (I /think/ that's what they are) appearing as grey bullets where you expect normal spaces. -- Cheers...

Differences between MySQL 4 and 5 for scripts
I have posted a similar question on the blojsom group but I feel I will have better chance of an answer here. Blojsom 3 was developed using MySQL5 for it's back end. However the host I am with uses 4.0.25 and are unwilling to upgrade - which is fair enough. So I decided to see what I can do to make the database creation scripts MySQL4 compliant. The CHARSET was the easy one - just change it to CHARACTER SET but the next one was more tricky: The problem I am having is that version 4 fails giving a syntax error for the single quotation marks. It appears the script (which was written on a Mac using MySQL dump 10.9 if that is any help) uses ` and not ', but doing a general search and replace doesn't fix it. I've searched the online docs regarding quotes but came up short (too many hits with too many unrelated items) so if anyone knows the exact url that would be helpful too. Here's a snippet of the code: DROP TABLE IF EXISTS `Blog`; CREATE TABLE `Blog` ( `blog_id` varchar(50) NOT NULL, PRIMARY KEY (`blog_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Thanks, G. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Re: Differences between MySQL 4 and 5 for scripts
Graham, I seem to recall those single quote marks working without a problem on various platforms and versions of MySQL. Of course they are generally just a nicety and only required if you are using reserved words as table/column/key names, so you could just remove them entirely. Could you post the exact error message you're getting please? Two thoughts - 1) You may have a bogus hidden character in your SQL file. If you look at it with a text editor (BBEdit, TextWrangler, etc), with the show invivisbles feature on, do you see unusual stuff? Sounds strange but I've seen stranger. 2) You could work around this problem a different way ... - create a 5.0 database yourself using the standard supplied scripts, perhaps on your own workstation - dump your new database structure using mysqldump with the flag --compatible=mysql40 which should create a file suitable for piping into a MySQL 4.0 server Dan Graham Reeds wrote: I have posted a similar question on the blojsom group but I feel I will have better chance of an answer here.

Thanks, G.
Single quotes (') are for strings. Backticks (`) are for identifiers. To the
best of my knowledge, this hasn't changed from 4.0 to 5. Hence, using your
table definition,
INSERT INTO `Blog` (`blog_id`) VALUES ('This is a blog id');
would be correctly quoted.
Strictly speaking, you only need to quote identifiers which wouldn't otherwise
be allowed (reserved words), so none of the backticks are needed in your example
(or in mine). See the manual for details:
http://dev.mysql.com/doc/refman/4.1/en/legal-names.html
http://dev.mysql.com/doc/refman/4.1/en/reserved-words.html
What leads you to believe your error is related to quoting? I think it is more
likely to be something else. If you post the query that gives the error and
include the exact error message, I'm sure someone will be able to identify the
problem.

MySQL 4 Kernel Panic-ing
I've got an xserve running 10.3.9 and MySQL 4.0.27-max that is restarting itself every 2-3 days. It appears that it is due to a kernel panic, though I don't have direct access to the machine (colocated) to verify when it occurs. There are no crash.logs from MySQL, and watchdog and system.logs show nothing. I have culled the following panic.log - can anyone tell if MySQL is the cause of such?

Re: MySQL 4 Kernel Panic-ing
Hi John - Yes, at my former workplace, we had a couple of different instances where we experienced severe crashing problems on G4-based machines. Prior to using a G4 Xserve, we were using a dual-G4 tower as our MySQL and Intranet server, and as we ramped up MySQL usage, the hard crashing got to where it was nearly every morning. Finally traced it to our backup process, Retrospect, accessing files while MySQL was trying to access them. Specifically excluding MySQL's data directory from your backup process is a must. Excluding temp and log dirs is also probably a good idea. We were already dumping out data out to another directory daily, but didn't realize that the simultaneous access would be such a problem. This was with MySQL 3.23 and later 4.0, and OS 10.1 through 10.2 I think. When we moved to a G4 Xserve (serving MySQL and our Intranet), we again had horrible crashing problems. Weird, like none I'd ever seen, where the OS basically just entered a slow spiral of death that led to it either rebooting on its own or us noticing the problem first and hard-resetting it. Apps would stop opening, cli processes would no longer run, running apps would slowly stop responding. Traced it to a pair of Kingston RAM modules. Once those were out, the machine righted itself and I believe continues to serve data (though no longer MySQL) to this day. Weird I know but I swear that was it. This was with MySQL 4.0 and (I think) OS 10.2 through 10.3. HTH, Dan John May wrote: I've got an xserve running 10.3.9 and MySQL 4.0.27-max that is restarting itself every 2-3 days.

Totally different join-behaviour in mysql 4 and 5?
As I already wrote I try do get a replication running from a mysql-4.1.13 (32bit) master to a 5.0.18 (64bit) slave. It only runs for a few minutes and then a query hangs. I think I now found out why: I modified a multi-table-update that hung to a select. The same query on the absolutely identical tables gives totally different explains on both systems: While my query has a cardinality of 23,124*1=23,124 on mysql4, it has 6,412*34,341=220,194,492 on mysql5 - and takes forever and makes me think everything hangs?! I verified this with a dump of to tables that I imported on various few different systems. I created a new test-database, piped the dump into that and ran the following queries.

Re: Totally different join-behaviour in mysql 4 and 5?
Comma separated JOINS strikes again!!! [...] Here is where you will find this change documented in the manual: http://dev.mysql.com/doc/refman/5.0/en/upgrading-from-4-1.html I read that page over and over again... probably too late at night. thanks for that info. Thanks to Peter, too. I made that select out of an multi-table update that hung in the processlist. That query came out of a very old script floating around... I found a few more and modified the updates, i think I shouldn't have that problem any more. I think nobody over here ever used comma-joins except for those few times. At least I hope so. ;) but that was only part of my problems, my replication still hangs every now and then... I'd be glad if you could have a look at my other postings 5.0.18-max-log as a slave of a 4.1.13-standard-log master problem - slave hangs. Maybe you have any ideas what I could try to get this working... thanks Jan -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Hello. From http://dev.mysql.com/doc/refman/5.0/en/union.html: ORDER BY for individual SELECT statements within parentheses has an effect only when combined with LIMIT. Otherwise, the ORDER BY is optimized away. Therefore you're getting the same results, because ORDER BY doen't work for your query.

It will stop working correctly, without giving any errors, as soon as your table gets to a certain size. Perhaps that will never happen in this particular case, but I think this sort of thing is a bad idea, in general. Your desire is to sort the rows of tablea. You want all the rows with item = 1 first, then all the rest. Within each group (item = 1, item != 1), you want the rows in random order. You should see that this is simply a two step ordering. Instead of trying to fake that with unioned queries, you should solve it directly in your ORDER BY clause. Both the query Gleb sent, SELECT * FROM tablea ORDER BY IF(item=1,0,1), RAND(); and the one I sent, SELECT * FROM tablea ORDER BY (item != 1), RAND(); do just that. Both will provide the results you asked for, and neither will break when the table reaches some particular size.

MySql v3.23 is part of the Fedore Core 3 distribution. MySQL v4.1 only became standard in Fedora Core 4. I suspect it's one of the non-Fedora repositories you're using.

UNIQUE issue at mysql 4.* and mysql 5.*
Hi all
I've created a table in mysql 4.1.12 and 5.0.9-beta-standard as follow
| manager_new | CREATE TABLE `manager_new` (
`id` bigint(20) NOT NULL auto_increment,
`id_from_hits` bigint(20) default NULL,
`from_ip` varchar(15) default NULL,
`pool` char(1) NOT NULL default 'n',
`to_ip` varchar(15) default '',
`lstupdate` date default NULL,
`comment` varchar(50) default NULL,
`added_by` enum('yariv','eddie','lisman','sweiss','interface') default
'interface',
`black_white` char(1) NOT NULL default 'B',
PRIMARY KEY (`id`),
UNIQUE KEY `from_ip` (`from_ip`,`to_ip`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
The two tables are EMPTY ,where I try this insert in each version I get :
mysql 5
mysql insert into manager_new
(id_from_hits,from_ip,to_ip,lstupdate,comment) values
(39,'192.118.68.5','192.118.68.5',now(),'added automatically');
ERROR 1062 (23000): Duplicate entry '192.118.68.5-192.118.68.5' for key 2
mysql 4
mysql insert into manager_new
(id_from_hits,from_ip,to_ip,lstupdate,comment) values
(39,'192.118.68.5','192.118.68.5',now(),'added automatically');
Query OK, 1 row affected (0.00 sec)
Is there any change in the way that mysql 5 treats UNIQUE index?
or is it a bug?
Best regards
Yariv

UNIQUE issue at mysql 4.* and mysql 5.*
Hi all
I've created a table in mysql 4.1.12 and 5.0.9-beta-standard as follow
| manager_new | CREATE TABLE `manager_new` (
`id` bigint(20) NOT NULL auto_increment,
`id_from_hits` bigint(20) default NULL,
`from_ip` varchar(15) default NULL,
`pool` char(1) NOT NULL default 'n',
`to_ip` varchar(15) default '',
`lstupdate` date default NULL,
`comment` varchar(50) default NULL,
`added_by` enum('yariv','eddie','lisman','sweiss','interface') default
'interface',
`black_white` char(1) NOT NULL default 'B',
PRIMARY KEY (`id`),
UNIQUE KEY `from_ip` (`from_ip`,`to_ip`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
The two tables are EMPTY ,where I try this insert in each version I get :
mysql 5
mysql insert into manager_new
(id_from_hits,from_ip,to_ip,lstupdate,comment) values
(39,'192.115.52.5','92.115.52.5',now(),'added automatically');
ERROR 1062 (23000): Duplicate entry '192.118.68.5-192.118.68.5' for key 2
mysql 4
mysql insert into manager_new
(id_from_hits,from_ip,to_ip,lstupdate,comment) values
(39,'192.115.52.5','192.115.52.5',now(),'added automatically');
Query OK, 1 row affected (0.00 sec)
Is there any change in the way that mysql 5 treats UNIQUE index?
or is it a bug?
Best regards
Yariv

compat RPM for MySQL 4.x on RHEL3 [PRESS RELEASE]
PD Inc. http://www.pdinc.us 156 Briarvista Way North East Atlanta, Georgia 30329-3615 +1(443)269-1555 EIN:52-2351863 August 1, 2005 Document#20050801P00 References#--- PRESS RELEASE: For immediate release. Contact:Ning Li [EMAIL PROTECTED] (443) 921-0381 PD Inc. has open-sourced their compatibility RPM that enables system administrators to install MySQL 4.x on Red Hat Enterprise Linux (RHEL3) Operating System with minimal impact. Baltimore -- August 1, 2005 -- PD Inc. today announced the release of their MySQL-shared compat RPMs for RHEL3. With these compatibility RPMs a system administrator can now upgrade to MySQL 4.x whilst keeping legacy libmysqlclient.so.10 and libmysqlclient.so.12 client libraries as provided by the RPMs and maintaining maximum Red Hat support compliance. Red Hat Enterprise Linux (RHEL) Operating System is one of the most commonly used open-source operating systems. More than 1/3 of the server market uses RHEL, including all Linux servers from IBM, and Dell. There are current limitations on RHEL support, limiting system administrators from reasonable deviations in application selection on the system. MySQL greater than 3.23 is not supported by Red Hat, Inc. on RHEL3. Normally to upgrade to MySQL 4.x many other applications on the system need to be upgraded and/or recompiled including Apache, PHP, and Perl. In doing so, Red Hat, Inc. no longer will support these system modifications. To solve this problem, PD Inc. has now released two compatibility RPM solutions. One for MySQL 4.0 and the other for MySQL 4.1. This open-source software allows system administrator to upgrade MySQL 4.x without upgrading other applications. With the a compat RPM, an IT department can minimize the non compliant applications installed, reduce the workload on staff, and ensure a smoother transition. These RPMs can be downloaded from: http://public.pdinc.us/rpms/mysql About Red Hat, Inc.

Re: Mysql 4.x Error
Hello. You have several problems and they're should be resolved step by step. First fix the problems with permissions. Usually they're solved by changing the owner of mysql database to mysql user. Check what's wrong with /var/log/mysqld.log. It might be necessery to create it manually. Why are you removing libssl.so.4. I think these libraries could exists both in the system. plaza c [EMAIL PROTECTED] wrote: Hi, Im using : mysqlclient10-3.23.58-6 ,mysql-server-4.1.11-2,mysql-4.1.11-2 On fedora 3. when i run the following command its gives Error: [EMAIL PROTECTED] etc]$ /etc/init.d/mysqld start touch: cannot touch `/var/log/mysqld.log': Permission denied chmod: changing permissions of `/var/log/mysqld.log': Operation not permitt= ed Initializing MySQL database: mkdir: cannot create directory `/var/lib/mysql/mysql': Permission denied chmod: cannot access `/var/lib/mysql/mysql': No such file or directory mkdir: cannot create directory `/var/lib/mysql/test': Permission denied chmod: cannot access `/var/lib/mysql/test': No such file or directory Installing all prepared tables /usr/libexec/mysqld: error while loading shared libraries: libssl.so.5: cannot open shared object file: No such file or directory Installation of system tables failed!

MySQL 4 Old Password
Is there a way to tell mysql 4 to defaul to the old style passwords instead
of having to run this every time we add a user?
SET PASSWORD FOR mailto:'user'@'localhost' 'user'@'localhost' =
OLD_PASSWORD('passowordo');
Applications we develop in php, and phpMyadmin don't seem to work with the
new style password.
Thanks!

Re: Fedora Core 2: upgrade mysql 3 to mysql 4
Hello. I want to upgrade mysql 3 to mysql 4. At first, you should read: http://dev.mysql.com/doc/mysql/en/upgrade.html Search the MySQL lists archives about possible problems which you can expect. It is strongly recommended to make a backup. How to remove mysql3 and install mysql 4? It depends on what kind of distribution you have. Probably rpm -U would help for the rpm distribution.

RE: Authorizing Problem in MySQL 4 with Mandrake 10
Be careful maybe you are mistaking here: the mysql root user as nothing to see with the mandrake root user. For exemple I lauch the mysql server as root from command line whereas I'm just a user on my desktop. So the mandrake root password and the mysql root password are also completly different. maybe this can be helpful: http://dev.mysql.com/doc/mysql/en/unix-post-installation.html From: Prabath Ranasinghe [EMAIL PROTECTED] (by way of Prabath Ranasinghe [EMAIL PROTECTED]) Reply-To: [EMAIL PROTECTED] To: mysql@lists.mysql.com Subject: Authorizing Problem in MySQL 4 with Mandrake 10 Date: Wed, 23 Feb 2005 18:46:29 -0500 -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hash: SHA1 Hi All, I installed a fresh copy of Mandrake Linux 10.0 with MySQL.

File locking mysql 4
Does mysql 4 require file locking? I'm not talking about in the database -- I know how to lock and unlock tables for data consistency. I'm referring to the filesystem that the data lives on. For reasons too boring to go in to, I have a mysql server and I'm keeping the database files (i.e., the var directory) on a filesystem that doesn't support file locking. Is this going to pose a problem? If this is being sent to the wrong mailing list, please point me to the right one.

Re: File locking mysql 4
MySQL itself doesn't require file locking. Infact there is an option to turn it off. --skip-external-locking that disables using the flock() system call. Just watch out that you don't accidently start two mysqlds on the same datadir. -Eric On 24 Jun 2004 13:42:33 -0700, Shelly Zhang [EMAIL PROTECTED] wrote: Does mysql 4 require file locking?

Re: bigint support in MySql 4
sorry, I don't know that one.

`timestamp` timestamp(14) NOT NULL,
`usuario` varchar(20) default NULL,
PRIMARY KEY (`empresa`,`tienda`)
) TYPE=MyISAM;
The condensed extract of the C program tha does the locking is as follows:
SQLinst = lock tables invcorr write, invfacturas write;
state = mysql_query(connection, SQLinst);
if(state != 0)
{
wxMessageBox(mysql_error(mysql), Error:, wxOK |
wxICON_EXCLAMATION,
this);
wxMessageBox(_(Could not lock table!), _(Error:), wxOK |
wxICON_EXCLAMATION, this);
return;
}
SQLinst = select ultfac from invcorr where empresa='
+ sCodigoEmp
+ ' and tienda='
+ sFacTienda
+ ' order by tienda;
state = mysql_query(connection, SQLinst);
result = mysql_store_result(connection);
if(mysql_num_rows(result) != 0) // Tiene registros
{
while((row = mysql_fetch_row(result)) != NULL)
{
// Asigno valores
sFacDocu = row[0] ? row[0] : ;
}
}
mysql_free_result(result);
sFacDocu.ToDouble(dFacDocu);
dFacDocu++;
sFacDocu.Printf(%09.0f, dFacDocu);
SQLinst = update invcorr set ultfac='

+ ' where empresa='
+ sCodigoEmp
+ ' and tienda='
+ sFacTienda + ';
state = mysql_query(connection, SQLinst);
SQLinst = unlock tables;
state = mysql_query(connection, SQLinst);
This final update is what seems to sleep and not react inmediately. The
application resides in one central server with dual Xeon 2.8 Ghz CPU's and 6
Gb RAM. All users run the application at the server connecting either via
ssh, VNC or Linux Terminal Server Project.
During the day, I will get 3 or 4 duplicate numbers per store. Given the fact
that reporting sales tax received, depends on a correct sequence of invoices,
my company could get into big trouble if authorities think we are trying to
avoid sales tax reporting.

MySQL 4 goes to sleep with table locks?
I am using Mandrake 9.1 and MySQL 4.0.11 from the LM CD's. In my application, I have a table that stores the sequential numbers of invoices prepared by several stores. Every time a salesman prepares an invoice for a customer, the system goes to this table, locks it with lock tables table write, reads the number of the last invoice made for that store, adds one to that number, updates the field, and unlocks the table. In theory, I should never get a duplicate invoice, but in practice, I do. So, it seems that MySQL maintains, under some special circumstances, the same number and does not update it. Maybe there is a parameter in my.cnf I could change to make sure all updates are processed inmediately? Auto increment field would not apply in this case, since there is only one record per store that gets updated for every invoice. I would appreciate any advise. Thank you. -- Alfredo J.
