Re: Better option then polling ?
Hello, I am fairly new to mysql and have a strange request I am not sure if stored procedures will solve this. I have a table in a database that is constantly being updated with new information. I would like to be notified if certain information gets committed. Lets say for example the table gets updated every time a login attempt happens regardless if it is successful or not. So I want an app to watch the table for incorrect logins and if found to send an e-mail. Now there are several problems with this ... first... there could be hundreds of logins so we do not want the same app to spawn multiple processes each notifying the same incorrect login attempt. I was thinking about a cron that would run every X minute searching any newly added rows and keeping the last row id in a tmp file. Is there a better way ? Well, as far as I know, not with MySQL. But you might request it for 5.0 ... Database engines like InterBase, Firebird and Oracle have event mechanisms. Clients can register interest in a particular event and whenever the database fires such an even, the client will be notified in an asynchronous manner. A trigger on your table could solve this problem then. Obviously, this is a much better way compared to polling. :-) But, as I said, as far as I know, MySQL doesn't support this (yet).

Re: How does one choose between MySQL and MaxDB?
Hello Darrell, all, this is a question which cannot be answered completely IMO. Also, as people's backgrounds differ, I may fail to find words which you understand the way I meant them - please take this into account. Am Do, den 10.03.2005 schrieb Darrell A. Sullivan, II um 17:17: Hello, I am planning to port some systems that are currently using proprietary database management to an SQL environment. In looking at the MySQL web site it appears that they have two different SQL database servers. I am trying to determine how to choose between the two. [[...]] Yes, these are distinct products: Both are DBMSs which speak SQL, but coming from separate code bases they have different properties / features and were (originally) targeted at different environments. Can anyone tell me what the practical day-to-day differences between the two products would be? MaxDB was targeted at the enterprise market from the start, with trained administrators, pre-planning of capacity, regular backups etc, whereas MySQL originally targeted fast application development, integration into Web servers, and embedding into applications. MySQL is now adding features which are essential for the enterprise market, whereas MaxDB is getting integrated into PHP etc. Still, both systems have their history and maybe never will be really similar. I looked at the documentation page that listed the differences between the two and it basically seemed as though MySQL was playing cath-up to MaxDB. In the sense that MaxDB already has some SQL features which MySQL is currently (or will be) adding, you are right. It is for you to check and decide how urgently you need these. Do not use older DBMS comparisons based on the status of MySQL 4.0 (or even 3.23), for any new setup you should take 4.1 (production) or even 5.0 (test, development - still alpha status). OTOH, MySQL has some properties that MaxDB does not have and IMO never will have - let me list just these: - different table handlers to choose from - the myisam table handler is extremely fast (no logging) and optimised for read-mostly situations - the multiple-version properties of InnoDB - various character sets and collation sequences, settable at DB, table, and even column level - replication (a former version of MaxDB offered distribution, and that was removed intentionally) However, considering how many people use MySQL there must be some driving reason behind that choice. I tried to give these above. The choice is for you to make.

Delays in replication and internet latency
Hi, We have replication running here and it has been excellent for a number of years. Recently we have been having lag in replication from London to Palo Alto (Plenty of bandwidth but a latency of 300ms round trip). The replications binlogs are being written at a rate of about 100MB to 200MB per hour and whilst we have no problems replicating to several servers that are reasonable close to the master, the Palo Alto server is getting over an hour behind at times. Does anyone know if there is something I can do to solve this? What experiences have others had in the past? Perhaps there is some way to increase the packet size or something to get over this latency problem... Or any other ideas?

Re: Multiple 1-1 tables better performance
Richard Lynch [EMAIL PROTECTED] wrote on 03/10/2005 05:13:09 PM: Apologies if this comes through twice... I *think* I fargled the To: the first time... My boss is claiming that having multiple 1-1 tables, with an index on the keys, is better performance. Example of his claim: table_1: person_id, name, phone table_2: person_id, address, city, state, zip, country is faster than: table: person_id, name, phone, address, city, state, zip, country Don't seem right to me that you'd get better performance by having the computer have to look up more crap, even if it is indexed. And surely SELECT name, phone FROM ... isn't going to be slowed down *THAT* much by the other data in the table sitting there unused... Is it? You can assume we're not dumb enough to do SELECT * FROM ... when we only need name and phone, okay? PS Since his largest table has way less than 1000 records, this question is largely academic anyway, and he should go for more maintainable and simpler schema. But I've given up on that argument. We might sell this to somebody someday with LOTS of records. Yeah, right. -- Like Music? http://l-i-e.com/artists.htm In my general experience, there are a few times when you need to split a single logical item across several physical tables (where there is a 1-1 between the tables for these records): a) You could put frequently accessed (or required) information on one table and rarely used (or optional) information on another. Smaller tables imply (but do not guarantee) faster response especially if one of the tables is a fixed-width table. b) You wanted/needed to use different ENGINES for different parts of the information. This occurs frequently in MySQL development when you want to use a fulltext index (MyISAM) on some fields while the rest of the data is stored in InnoDB. c) You want to assign separate permissions to groups of columns. You can put each group into their own table. This is related to but slightly different than column-level permissions. Fortunately, MySQL supports both design choices. Then there is the case of normalization. I can understand keeping phone numbers and addresses on separate tables than the person's name, birthdate, and other bits of unique information. People only get one set of names (not counting aliases, they would get a separate table) but they can have multiple phone numbers (home phone, work phone, fax machine, cell phone, etc.) and multiple addresses (work address, home address, vacation address, etc.). It makes great sense to split that kind of associated information into their own tables so that you can create 1-n relationships. However, if you have just 1-1 information and neither table is fixed width, and you do not have any of the other reasons (and I am sure there are more) that I outlined above, then you will be better served by keeping the information in a single table. Here is some more ammunition for your argument. The single slowest thing about using a database is using the hard disk. Each read request takes some average time (from 1ms to 100ms or more, depending on hardware) to find and retrieve any single block of information from the physical recording media. disclaimer THIS IS NOT AN OFFICIAL MYSQL EXAMPLE BUT IS MEANT TO BE REPRESENTATIVE OF HOW MANY DATABASES OPERATE Say you want to find a record whose PK value is 16. (If we assume that the OS has already cached the physical file information, then we can eliminate disk reads of the file allocation indexes in order to locate each file). seek 1 - find the first record of PK index file seek 2 - scan/search the index file for record with value 16. Get the offset of the data record in the data file from this index record. seek 3 - Use the offset found in the index to position the read heads at the beginning of the data record in the data file. seek 4 - Scan the disk to read record the entire record into memory (this is usually faster (by a factor of 10 or more) than any of the other previous steps). In essence this takes nearly no time compared to all of the other seeking we have to do just to get to this point. /disclaimer So by forcing the database to read one logical record from multiple physical tables (if it doesn't need to be arranged that way due to other reasons), your boss is forcing that cycle to repeat several times while if it were all on one table you would go through that cycle once and be done with it.

Re: Replication only DB
Remember replicate-do-db doesn't look at queries to decide which ones to replicate. It only looks at the USE flag. This is very important: manual snip http://dev.mysql.com/doc/mysql/en/replication-options.html Tells the slave to restrict replication to statements where the default database (that is, the one selected by USE) is db_name. To specify more than one database, use this option multiple times, once for each database. Note that this does not replicate cross-database statements such as UPDATE some_db.some_table SET foo='bar' while having selected a different database or no database. If you need cross-database updates to work, make sure that you have MySQL 3.23.28 or later, and use --replicate-wild-do-table=db_name.%. /manual snip -Eric On Fri, 11 Mar 2005 09:36:53 -0600, Peter Brawley [EMAIL PROTECTED] wrote: replicate-do-db came in with 3.23.16, and it's in the manual (though the online search engine mishandles a search for 'replicate-do-db'--look under 'Replication startup options').

How to determine how many ibdata files are needed?
Using MySQL 4.1.10, SuSE 8.2 Pro, reiser file system. Hi: I have been trying to locate a reference which would provide guidelines to determine if one ibdata should be used, or when to use several (two, three, etc.), but I can not seem to find anything in the manual. I have tried a single ibdata file for my 5 Gb database (which is going to grow as history gets added to it), two and even three ibdata files, the last with the autoextend argument. I have not seen a difference in performance so far. Is there any advantages to having one single ibdata file, or is it better to have several, and if so, how many? If you could point me to a url where I can read about this, I would greatly appreciate it. Thank you and regards. -- Alfredo J.

I wish Mysql has such configuration option for that in future release. Sam, That *may* be good to hear. I've used other databases that keep record counts in the index so any Select statement will return an accurate and fast record count. However it slows down the inserts/updates as it has to maintain these index counts as each record is added. So I hope this new mySQL feature can be turned off if necessary. You usually don't get a new feature like this without a speed penalty somewhere.

MySQL 4.1.10a has been released
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, MySQL 4.1.10a, a new version of the popular Open Source/Free Software Database Management System, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://dev.mysql.com/downloads/ and mirror sites. Note that not all mirror sites may be up to date at this point in time - if you can't find this version on some mirror, please try again later or choose another download site. This MySQL 4.1.10a release just includes the additional patches for recently reported potential security vulnerabilites in the creation of temporary table file names and the handling of User Defined Functions (UDFs). We would like to thank Stefano Di Paola [EMAIL PROTECTED] for finding and reporting these to us. Please note that these changes affect the way in which User Defined Functions (UDF) are loaded. Please refer to the section User-defined Function Security Precautions in the manual: http://dev.mysql.com/doc/mysql/en/udf-security.html Functionality added or changed relative to 4.1.10: * Security improvement: The server creates `.frm', `.MYD', `.MYI', `.MRG', `.ISD', and `.ISM' table files only if a file with the same name does not already exist. * Security improvement: User-defined functions should have at least one symbol defined in addition to the `xxx' symbol that corresponds to the main `xxx()' function. These auxiliary symbols correspond to the `xxx_init()', `xxx_deinit()', `xxx_reset()', `xxx_clear()', and `xxx_add()' functions. `mysqld' by default no longer loads UDFs unless they have at least one auxiliary symbol defined in addition to the main symbol. The '--allow-suspicious-udfs' option controls whether UDFs that have only an `xxx' symbol can be loaded. By default, the option is off. `mysqld' also checks UDF filenames when it reads them from the `mysql.func' table and rejects those that contain directory pathname separator characters. (It already checked names as given in `CREATE FUNCTION' statements.) See the section in the manual on writing UDFs.

MySQL 4.0.24 has been released
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, MySQL 4.0.24, a new version of the popular Open Source/Free Software Database Management System, has been released. It is now available in source and binary form for a number of platforms from our download pages at http://dev.mysql.com/downloads/ and mirror sites. Note that not all mirror sites may be up to date at this point in time - if you can't find this version on some mirror, please try again later or choose another download site. This is a bugfix release for the recent production version. It also includes fixes for recently reported potential security vulnerabilites in the creation of temporary table file names and the handling of User Defined Functions (UDFs). We would like to thank Stefano Di Paola [EMAIL PROTECTED] for finding and reporting these to us. Note that these changes affect the way in which User Defined Functions (UDF) are loaded. Please refer to the section User-defined Function Security Precautions in the manual: http://dev.mysql.com/doc/mysql/en/udf-security.html Please refer to our bug database at http://bugs.mysql.com/ for more details about the individual bugs fixed in this version. News from the ChangeLog: Functionality added or changed: * Security improvement: The server creates `.frm', `.MYD', `.MYI', `.MRG', `.ISD', and `.ISM' table files only if a file with the same name does not already exist. * Security improvement: User-defined functions should have at least one symbol defined in addition to the `xxx' symbol that corresponds to the main `xxx()' function. These auxiliary symbols correspond to the `xxx_init()', `xxx_deinit()', `xxx_reset()', `xxx_clear()', and `xxx_add()' functions. `mysqld' by default no longer loads UDFs unless they have at least one auxiliary symbol defined in addition to the main symbol.

By default, the option is off. `mysqld' also checks UDF filenames when it reads them from the `mysql.func' table and rejects those that contain directory pathname separator characters. (It already checked names as given in `CREATE FUNCTION' statements.) See the section in the manual on writing UDFs. * `InnoDB': Added configuration option and settable global variable `innodb_autoextend_increment' for setting the size in megabytes by which `InnoDB' tablespaces are extended when they become full. The default value is 8, corresponding to the fixed increment of 8MB in previous versions of MySQL. * InnoDB: Do not acquire an internal `InnoDB' table lock in `LOCK TABLES' if `AUTOCOMMIT=1'. This helps in porting old `MyISAM' applications to `InnoDB'. `InnoDB' table locks in that case caused deadlocks very easily. Bugs fixed: * `FOUND_ROWS()' returned an incorrect value after a `SELECT SQL_CALC_FOUND_ROWS DISTINCT' statement that selected constants and included `GROUP BY' and `LIMIT' clauses. (Bug #7945) * Queries of the form `(SELECT ...) ORDER BY ...' were being treated as a `UNION'. This improperly resulted in only distinct values being returned (because `UNION' by default eliminates.) (Bug #7672) * Index cardinality was not being updated properly for `TEMPOARY' tables under some circumstances, such as `CREATE TABLE ... SELECT' followed by `ANALYZE TABLE'. (Bug #7519) * Fixed a server crash caused by `DELETE FROM TBL_NAME ... WHERE ... ORDER BY TBL_NAME.COL_NAME' when the `ORDER BY' column was qualified with the table name. (Bug #8392) * Fixed a bug in `MATCH ... AGAINST' in natural language mode that could cause a server crash if the `FULLTEXT' index was not used in a join (`EXPLAIN' did not show `fulltext' join mode) and the search query matched no rows in the table (Bug #8522). * Platform and architecture information in version information produced for `--version' option on Windows was always `Win95/Win98 (i32)'. More accurately determine platform as `Win32' or `Win64' for 32-bit or 64-bit Windows, and architecture as `ia32' for x86, `ia64' for Itanium, and `axp' for Alpha. (Bug #4445) * `InnoDB': Honor the `--tmpdir' startup option when creating temporary files. Previously, `InnoDB' temporary files were always created in the temporary directory of the operating system. On Netware, `InnoDB' will continue to ignore `--tmpdir'. (Bug #5822) * Fixed an optimization problem that allowed a negative number to be stored in a `DOUBLE UNSIGNED' column when it was assigned a value from a signed `DOUBLE' column. (Bug #7700) * Fixed a failure of multiple-table updates to replicate properly on slave servers when `--replicate-*-table' options had been specified. (Bug #7011) * Renamed `set_bit()' and `clear_bit()' functions in source

Re: configuring Mysql Query Browser with charset latin5
Hello. The general way to order a MySQL client to use some encoding is to execute SET NAMES 'encoding'. See: http://dev.mysql.com/doc/mysql/en/charset-connection.html But, as said at: http://bugs.mysql.com/bug.php?id=6982 Query Browser starts a new session for every new query, except when you start a transaction. And your previous SET NAMES doesn't have an effect. So, you may start a transaction, and then execute SET NAMES. During all transaction your character_set_xxx variables should have the same values.

Re: Better option then polling ?
There's nothing wrong with polling as long as it's moderate and it doesn't lock resources. On a heavily updated table in a large volumen site, it scales much better than nasty triggers or events firing all over the place. Triggers are intended to maintain internal database consistency by enforcing business rules at the DB tier. They're not meant for event notification of external applications, especially if you're holding the transaction hostage until the remote call is completed. As someone mentioned here, asynchronous events (fire'n'forget) in some DBMS systems are much better suited to this because they don't don't prolong transactions, and subsequently locks on resources. I think the best choice in your scenario is to use adaptive polling: Track the average of DELTA (new records added between polls) over time, and adjust the polling internval accordingly. For example, if the current average DELTA is 100, and the new DELTA was 120, then you decrease the polling interval proportionally but not less than MIN value, and if it was 80, then you increase the polling interval proportionally but not greater than MAX value. This way you can adapt well to surges in events and prevent queue buildups. Homam --- Michael Gale [EMAIL PROTECTED] wrote: Hello, I am fairly new to mysql and have a strange request I am not sure if stored procedures will solve this. I have a table in a database that is constantly being updated with new information. I would like to be notified if certain information gets committed. Lets say for example the table gets updated every time a login attempt happens regardless if it is successful or not. So I want an app to watch the table for incorrect logins and if found to send an e-mail. Now there are several problems with this ... first... there could be hundreds of logins so we do not want the same app to spawn multiple processes each notifying the same incorrect login attempt. I was thinking about a cron that would run every X minute searching any newly added rows and keeping the last row id in a tmp file. Is there a better way ? Thanks.

Re: Lock timeout problem
Mauricio, - Original Message - From: Mauricio Pellegrini [EMAIL PROTECTED] Newsgroups: mailing.database.myodbc Sent: Friday, March 11, 2005 9:13 PM Subject: Lock timeout problem Hi, we are using mysql 4.1.4-gamma and a few days ago we started to receive lock wait timeout messages from within our application also on other connections via tcp/ip ( from mysql clients ) the same thing happens While we are trying to discover what is causing these errors I've noted this in the output of SHOW ENGINE INNODB STATUS this is the text: ---TRANSACTION 0 735105891, ACTIVE 1812 sec, process no 24059, OS thread id 1741492237 225 lock struct(s), heap size 27968, undo log entries 12427 use SHOW PROCESSLIST to determine if you have a dangling session. You should commit your transaction. It looks like someone forgot to commit a big transaction. Question #1. Can I identify the query that was running in that transaction? I Think it may not be inside the binary log as we had to stop the server and start it again . Question #2. What does the 225 lock struct(s) mean It means appromately that the transaction has locks on 225 pages or 225 tables.

Re: Better option then polling ?
There's nothing wrong with polling as long as it's moderate and it doesn't lock resources. On a heavily updated table in a large volumen site, it scales much better than nasty triggers or events firing all over the place. Triggers are intended to maintain internal database consistency by enforcing business rules at the DB tier. They're not meant for event notification of external applications, especially if you're holding the transaction hostage until the remote call is completed. Enforcing business rules? If you can put your rules into constraints, do it and drop the triggers. Triggers can be used for anything you like. Firing events can be one of them. As someone mentioned here, asynchronous events (fire'n'forget) in some DBMS systems are much better suited to this because they don't don't prolong transactions, and subsequently locks on resources. I think the best choice in your scenario is to use adaptive polling: Track the average of DELTA (new records added between polls) over time, and adjust the polling internval accordingly. For example, if the current average DELTA is 100, and the new DELTA was 120, then you decrease the polling interval proportionally but not less than MIN value, and if it was 80, then you increase the polling interval proportionally but not greater than MAX value. This sounds like usuable advice.

mysql error nr.0
Using MySQL version 4.0, I am trying to backup my database using MySQL Administrator. When executing the backup I get error mysql error nr.0 which doesn't tell me much. I did a Google search on the error and it didn't tell me much. Can anyone shed light on this error message? Thanks. Darin Vanatta [EMAIL PROTECTED] __ Do you Yahoo!? Yahoo!

./mysql_install_db: line 86: my_print_defaults: command not found
Hi All, after experiencing trouble with the rpm install on Fedora3, I went with the tar install. All went well, until I got to this part of the install manual, After you complete the procedure and have the server running, you should assign passwords to the accounts created by *mysql_install_db*. Instructions for doing so are given in Section 2.9.3, Securing the Initial MySQL Accounts http://dev.mysql.com/doc/mysql/en/default-privileges.html. In the examples shown here, the server runs under the user ID of the |mysql| login account. This assumes that such an account exists. Either create the account if it does not exist, or substitute the name of a different existing login account that you plan to use for running the server. 1. Change location into the top-level directory of your MySQL installation, represented here by /|BASEDIR|/: shell cd /|BASEDIR|/ /|BASEDIR|/ is likely to be something like |/usr/local/mysql| or |/usr/local|. The following steps assume that you are located in this directory. 2. If necessary, run the *mysql_install_db* program to set up the initial MySQL grant tables containing the privileges that determine how users are allowed to connect to the server. You'll need to do this if you used a distribution type that doesn't run the program for you. Typically, *mysql_install_db* needs to be run only the first time you install MySQL, so you can skip this step if you are upgrading an existing installation, However, *mysql_install_db* does not overwrite any existing privilege tables, so it should be safe to run in any circumstances. To initialize the grant tables, use one of the following commands, depending on whether *mysql_install_db* is located in the |bin| or |scripts| directory: shell bin/mysql_install_db --user=mysql shell scripts/mysql_install_db --user=mysql Below is what I did, [EMAIL PROTECTED] scripts]# mysql_install_db --user=mysql -bash: mysql_install_db: command not found [EMAIL PROTECTED] scripts]# ./mysql_install_db --user=mysql ./mysql_install_db: line 86: my_print_defaults: command not found Could not find help file 'fill_help_tables.sql' in ./support-files or inside .. I guess I'm missing something quite fundamental, yes..? Just can't think what. Anyone see the obvious.? Cheers.

insert - select from two different applications race condition?
I have a simple problem... I'm using mysql 4.1.9/innodb table and two small python applications A and B first application A is executed, and do a simple INSERT into a table then application B is executed: - B does a SELECT in the same table, that should return the entry created by application A (and based on the result, an UPDATE (to the entry application A has created) or an INSERT if it can't find it... but in this scenario it should find it since B is always executed just after A is) I can be sure that application A is executed before application B is started, even though B can be started just after A is done. The problem is that every once in a while, the SELECT doesn't return anything... even though I can check that application A created the entry... Everything looks as if the INSERT from application A hasn't completed when the SELECT in the application B is performed... Even though application A terminated before application B started! Any clue about what's going on? How can I prevent that? thanks -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
Problem: Too many connections
Hi, I have a live site using mysql. It is heavily used with over thousand users per minute, with 3 select / update queries per user per minute accounting to over 3000 queries per minute. The problem is that many times connection to this mysql server fails with the error Too many connection also sometimes the server becomes down bcoz of overload. The server has around 4GB of RAM with mysql version of 4.0.23 So my question is , is the problem related with just tuning of configuration parameters or can the problem be solved by any means too. Any kind of help is deeply appreciated. Thanks in advance, Sapna
