Replication problems: slave fails to update
I'm trying to resolve a frustrating replication problem with my databases. The master contains a number of schema, only using Innodb tables. Updates happen regularly, usually using bulk inserts of the form INSERT ... ON DUPLICATE UPDATE. Data is mostly numbers. The missing queries contain no non-deterministic functions, no BLOB/TEXT fields, no triggers or procedures, and no variables. The queries are generated by various C programs, connecting through Connector/ODBC. typical table (explain results): 'nodeID', 'int(10) unsigned', 'NO', 'PRI', '', '' 'calculationID', 'int(10) unsigned', 'NO', 'PRI', '', '' 'columnID', 'tinyint(3) unsigned', 'NO', 'PRI', '1', '' 'value', 'double', 'NO', '', '', '' 'lastUpdate', 'timestamp', 'NO', '', 'CURRENT_TIMESTAMP', 'on update CURRENT_TIMESTAMP typical bulk insert: INSERT INTO risk.risk_node_tree (nodeID, calculationID, columnID, value, lastUpdate) VALUES (1,2,1,1000,null),... ON DUPLICATE KEY UPDATE value=VALUES(value) Replication is active, and I am able to test it by doing single point modifications through the query browser. However, the bulk inserts seem to vanish: The Master updates, but the slave does not. There are no errors in the log file. SHOW SLAVE STATUS states no problems. I have attempted changing binlog_format, and have received the same results on all three settings. The Master has no settings to ignore any particular schema. Using the query browser, and running the same exact query with the same user, results in the query properly replicating. Both instances are 5.1.34. This is causing me to have to resynchronize the databases every night, which is getting to be something of a chore. Does anyone have any idea what might be happening, or could suggest an avenue of investigation? Any help would be greatly appreciated.

replication problems
I have a simple master-slave replication setup. Nothing very interesting as far as I know, both running identically configured 5.1.31 using 'mixed' replication. I have a couple of issues which I assume are related, although I suppose they might not be: 1) When the monitoring showed that slaving had stopped, I found the last_sql_error which was about a foreign key constraint failing. Is it possible that the queries against the master get into the bin log out of order so that a referent was changed while there were still outstanding references to it? If not, how is it possible that the query would succeed on the master but not on the slave? 2) Unable to get quick answers to that I decided that safest and easiest would be to take a dump of the master and use it to create a new slave from scratch. However, one of my databases failed to load into the new slave, with an Identifier too long (error 1509). But this dumpfile came from the master. If it's ok on the master, how can it be too long for the slave? And of course, the real question is how do I stop this happening again? Is it something wrong with my mysql server setup? Or is it bad code on the part of my users? And if the latter, what can I do to prevent their bad code making my slaving fail? -- Duncan Hutty System Administrator, ECE Carnegie Mellon University Please use informative subject lines -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=arch...@jab.org

Replication problems - packet sizes and more
My master has two databases: channel and hardware. I'm only interested in replicating hardware, so I set up replicate-do-db=hardware on the slaves. However, I am having problems because of giant LOAD DATA operations performed nightly on channel. Replication blows up with max packet exceeded errors. Due to this weird java program we have to use to load data from our partner, I can't just make the packet size really large on the master and slave and be done with it. I tried doing that, but the java program freaks out if i set mysql's packet size too big for the java heap. (I hate java so much.) So, my questions are: - does anyone know how to make java not care how big the mysql packet is? - is there any way to have the mysql master just not even send big packets to the slaves? - is there any way to make the mysql slaves ignore too-big packets? they are only happening on a database that i don't want to replicate anyway. thanks -jsd- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

Not really fixable, due to the way the MySQL protocol works, a query (including the data for LOAD DATA LOCAL INFILE) has to fit in an entire packet, the packet size needs to be sent to the server _first_, so that means the clients have to allocate all memory required for a query, plus some overhead to escape any 'special' characters...The c-based client would have problems as well (it would have to allocate just as much memory), you just wouldn't get an exception, your program would end up in swap instead. The JDBC client only grows the packet to max_allowed_packet if it needs to. The one case where it probably doesn't need to is for LOAD DATA LOCAL INFILEThe C-library implementation of LOAD DATA LOCAL INFILE _does_ use max_allowed_packet sized packets to send the file from client - - server. Are you using LOAD DATA LOCAL INFILE with JDBC? If so, check out a nightly build of Connector/J 3.1.x from http://downloads.mysql.com/snapshots.php ... It has a change to it where it will use the smaller of 1MB or max_allowed_packet for LOAD DATA LOCAL INFILE operations (this still works, it's just not the 'normal' way the client library works). -Mark - -- Mark Matthews MySQL AB, Software Development Manager - Client Connectivity Office: +1 708 332 0507 www.mysql.com -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBpTKctvXNTca6JD8RArT9AJ4/gvtsg3u9449Kk8y7N62zglfZOQCgrcXq Ga820/B6m+joEVsKueFf/18= =UHTi -END PGP SIGNATURE- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

I tried writing a Perl script to run a query of SHOW SLAVE STATUS and
parsing the 30-or-so fields that would otherwise return, but it's
complaining:
DBD::mysql::st execute failed: Access denied; you need the
SUPER,REPLICATION CLIENT privilege for this operation at ./checkslave.pl

Snippet of code:
my $dbh_2 =
DBI-connect(dbi:mysql:ouofa:slave2.domain.org,systemcheck,mypasswd,
{ RaiseError = 1, AutoCommit = 0, PrintError = 0 } ) or die
(SLAVE2 MySQL database offline: $!) ;
my $cur_info = $dbh_2-prepare(SHOW SLAVE STATUS) ;
$cur_info-execute() ;
my @row = $cur_info-fetchrow_array() ;
... line 19 would be the -execute() call.
I did this:
GRANT SUPER,REPLICATION CLIENT to 'syscheck'@'mywebserver.domain.org'
IDENTIFIED BY 'mypasswd' ;
... on the slaves, but that didn't help me any.
How can I check a slave's status without having to manually log in to a

Transaction Replication Problems
Has anyone ever encountered a problem where replication stops due to a partially completed query on the master? I am currently encountering this problem on my server and was wondering if I need to resync the slave server to the master by copying all the data files to the slave and then restarting replication. Is this my best action? The error I am receiving is: 040820 14:51:56 Slave: query 'BEGIN' partially completed on the master and was aborted. There is a chance that your master is inconsistent at this point. If you are sure that your master is ok, run this query manually on the slave and then restart the slave with SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; SLAVE START; . Error_code: 1158 040820 14:51:56 Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with SLAVE START.

Re: Replication problems
That got me greping through my Master's log and I came accross the following : Error reading packet from server: log event entry exceeded max_allowed_packet - increase max_allowed_packet on master (server_errno=65535) This seems to have happened in the date ranges where replication was failing. I cant confirm it is related but is it possible this would cause replication to fail on the server ? Also a new table is created every day therefore a single failure cant have been the reason for replication failure over a period of time. It also brings me to a critical question what do I set as the max_allowed_packet so that I will successfully save all updates to a TEXT field? TEXT fields dont have a size limit so how do I make sure I will never see this error ?

Various replication problems with 4.0.10-gamma
Hi, I'm having a bit of a nightmare getting replication working. Both slave and master are 4.0.10-gamma If I install fresh copies on two clean machines, and follow the instructions in manual.txt, everything works fine. The problem is that I need to do this in a production environment, so I can't quite follow the instructions. I've tried using LOAD DATA FROM MASTER, but this aborts and the logfile shows a ER_NET_MASTER_READ has occurred in the middle of the third table. So, I removed the mysql data directory on the slave, and completely re-installed and re-populated it (just to be sure I had a clean start). Then tried again by taking a snapshot - Just one database to start with. I then tried a CHANGE MASTER TO ... and SLAVE START This now fails with: 030218 14:21:53 Error updating slave list: Query error It seems that replication is trying to do a SHOW SLAVE HOSTS. I assume that this is running on the master, so I tried to login to the master by hand and run it to see what the error is. I get the error: ERROR 1227: Access denied. You need the REPLICATION SLAVE privilege for this operation I've tried setting the grants again, but it doesn't seem to make any difference: mysql GRANT REPLICATION SLAVE,RELOAD,SUPER ON *.* TO myuser@myhost IDENTIFIED BY 'mypass' mysql show grants for myuser@myhost; ++ | Grants for myuser@myhost | | ++ | GRANT RELOAD ON *.* TO 'myuser'@'myhost' IDENTIFIED BY PASSWORD 'asdadadasdadasas' | | ++ 1 row in set (0.00 sec) Whats going on here ?

Hi All I am trying to make a replication for my database. The master and the slave both in version 3.23.41 and i am working on windows 2000. I create user with FILE privilege and I flush all the tables and block write queries. Now I run the query SHOW MASTER STATUS and I get null in all the columns (file, position, Binlog_do_db and Binlog_ignore_db) What should I do?

Replication Problems with Adding New Records
I am using MySQL version 4.0.10 on both Slave and Master. I am running a Visual Basic front end connected to MySQL via MySQL ODBC v3.51.04. When using MySQLCC, adding records to the master database will work fine, the server shows the additional record added. When using our app in VB, a record will be added on the Master, but the Slave does not pick up the added record. The log-bin file shows there is something recorded, but no error message or no change! If anyone has any input, that would be great... If you need or want further explaining please email, I will be glad to help... Thanks...

replication problems with InnoDB tables...?
So I have been reading a lot lately about replication but I can't find a good summary/explanation of MySQL's replication features regarding InnoDB tables and how their transactional properties may cause problems in replication. I have seen suggestions that InnoDB tables should be converted to MyISAM tables before being loaded and then converted back to InnoDB tables. I have also seen many others here confused as to what problems there are between InnoDB and replication. So, could some friendly MySQL guru please explain to me, and many others, what the replication issues with InnoDB tables really are...please? The docs state that InnoDB is replication safe yet there seem to be so many problems with them when updates fail, roll back or are partially executed because some constraint conflict that causes replication to stop.

Kris, - Original Message - From: Krzysztof Karski [EMAIL PROTECTED] Newsgroups: mailing.database.mysql Sent: Tuesday, January 21, 2003 11:35 AM Subject: replication problems with InnoDB tables...? So I have been reading a lot lately about replication but I can't find a good summary/explanation of MySQL's replication features regarding InnoDB tables and how their transactional properties may cause problems in replication. transactions should not cause problems in replication. However, a relevant bug fix is this: MySQL/InnoDB-4.0.6, December 19, 2002 ... Fixed a bug: in replication issuing SLAVE STOP in the middle of a multi-statement transaction could cause that SLAVE START would only perform part of the transaction. A similar error could occur if the slave crashed and was restarted. I have seen suggestions that InnoDB tables should be converted to MyISAM tables before being loaded and then converted back to InnoDB tables. LOAD TABLE FROM MASTER only works for MyISAM tables. To set up a new replication slave you should use a cold backup, or a hot backup made with the non-free InnoDB tool. I have also seen many others here confused as to what problems there are between InnoDB and replication. So, could some friendly MySQL guru please explain to me, and many others, what the replication issues with InnoDB tables really are...please? The docs state that InnoDB is replication safe yet there seem to be so many problems with them when updates fail, roll back or are partially executed because some constraint conflict that causes replication to stop. A relevant bug fix: MySQL/InnoDB-4.0.6, December 19, 2002 ... Fixed two bugs introduced in 4.0.4: in AUTO_INCREMENT, REPLACE could cause the counter to be left 1 too low. A deadlock or a lock wait timeout could cause the same problem. MySQL does not write to the binlog SQL statements which fail. It does not write to the binlog any SQL statements from a transaction which is rolled back. Thus, these are never replicated, and in the slave there should not be any constraint violation errors.

Redhat 8.0 MySQL 3.23.52-3 Replication Problems
I have been having a lot of trouble configuring mysql to do just the simplest replication. Its a standard RedHat 8.0 install, I have followed the directions on http://www.mysql.com/doc/en/Replication_HOWTO.html to the letter half a dozen times now and still, the slave server crashes repeatedly as soon as I enter SLAVE START command. Number of processes running now: 1 mysqld process hanging, pid 26754 - killed 030113 17:54:33 mysqld restarted /usr/libexec/mysqld: ready for connections Number of processes running now: 1 mysqld process hanging, pid 26778 - killed 030113 17:54:34 mysqld restarted /usr/libexec/mysqld: ready for connections Above is what is logged. I eventually have to kill the process and try again. I have tried entering master login/bin-log information in my.cnf and using CHANGE MASTER TO... while logged into slave mysql server. Neither method works. Was wondering if anyone had some insight into this problem. I would be happy to provide more information.

replication problems
We have two users, lets call them test and test2. When we log in as test from our front end web servers, we can execute queries and they replicate. When we log in as test from our back end db servers (say to run a cleanup script by hand), the queries replicate. When we log in as test2 from our back end db servers (as part of a periodic process), it replicates the queries. When we log in from our front end web servers as test2, the queries do not replicate. They are never added to the binary update log. Otherwise, everything appears to work fine; the master db server runs the queries and updates the tables appropriately. If necessary I can upload a copy of our grant table, but I'm hoping someone has a quick. easy fix. :) Thanks - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

mysql replication problems
dear everybody, I have tree linux 7.3 machines on which MySQL-3.23.51-1.i386.rpm, MySQL-client-3.23.51-1.i386.rpm and MySQL-shared-3.23.51-1.i386.rpm is installed. the intrusion detection system snort loggs to these machines. Every machine is set up the same way and contains the same table. The data of these three tables is always different. this works well, but now I want to have a place/machine where I can read the data of these three tables. Maybe I can set up a master to which all the other databases can log their data? Or perhaps I can configure every machine as master and as slave at the same time and thus every machine contains the whole data of these three machines. I am a newbie in mysql and don't know how to do it. I read the following link : http://www.mysql.com/doc/en/Replication.html but I don't know if mysql meets my requirements. Anyway I tried to configure two of my databases like the example configuration. I had no problem with the master. then I tried to set up the slave and couldn't find the my.cnf, the mysqld and the mysqld.log files. I set up the two machines the same way!! Perhaps I used the wrong softare, but why exit the files on the other machine? thanks for your help martina podesser FLEXTRONICS World Trade Center A-1300 Vienna Austria [EMAIL PROTECTED] www.flextronics.com - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

mysql replication problems
Both my slave server say they are replicating correctly in the mysqld.log but they arn't. Any change made to the master is not reflected to the slaves. I have tried reseting the master and slaves but didn't change anything. Also tried redumping the databases to the slaves but that didn't effect anything. Anyone have any ideas?

Re: replication problems
I'm having the same problems, but I've noticed that the reported error doesn't seem to be a real failure. The databases seem to be updated correctly. When I look at my slave error log, I can see that the at position is a number that always matches the size of the log file on the master. This cannot be a coincidence. Is it perhaps trying to read past the end of the log file or something? I haven't really looked at MySql in years because it's been working fine, but in setting up replication, I see now that I have some Innobase tables, some not. Haven't a clue how that happened, but my my.cnf does not have the related directives uncommented. This could be related to problems reading the logs, I assume? I'm doing some testing, but any suggestions appreciated. I don't have a spare server to play with and the master is our main production server, so I have to play carefully to remain employed. I tried with both master and slave running mysql-3.23.47-pc-linux-gnu-i686 and then tried moving the slave to 3..23.51 with the same error results.

Re: replication problems -- resolution
Just to let you know that when I installed 3.23.51 binary on both Debian Linux boxes, same problem, but when I re-installed the 3.23.49a binary on both boxes the problem went away. Uncertain why.

Fix the problem, and re-start the slave thread with mysqladmin start-slave. ERROR: 1051 Unknown table 'TB_Tage,TB_Tage' Sounds, as if you were doing some cross database updates / inserts. This might lead to problems if you only replicate some of the databases on the master. So, if there is a Database A, B, C, D on master each with tables A1,A2,A3 or B1,B2,B3 and so on, and you only replicate A and B and you do: use A; insert into C.C1 (a,b,c) VALUES (1,2,3); you'll get this error. You might avoid it with replicate-wild-ignore-table=C.* More details in: http://www.mysql.com/documentation/mysql/bychapter/manual_My SQL_Database_Administration.html#Replication_Options But note that: use C; insert into A.A1 (a,b,c) VALUES (1,2,3); would not be replicated to the slave, if you choosed to replicate only A and B. Even though it affects A. (Strange, but that's the way live goes). At least with MySQL 3.23.36 So best is to avoid cross-databases actions except for SELECT with replication enabled.

Replication Problems
Hy all, I just try to set up Replication with two mysql databases, i did everything like described in the Replication-Howto. Now i get the following errors when starting the slave: 020117 18:37:55 mysqld started Can't initialize InnoDB as 'innodb_data_file_path' is not set /usr/sbin/mysqld-max: ready for connections 020117 18:37:55 Slave: connected to master '[EMAIL PROTECTED]:3306', replication started in log 'samba-bin.001' at position 536 ERROR: 1017 Can't find file: './tropon_001/Tagesberichte.frm' (errno: 13) 020117 18:37:55 Slave: error running query 'CREATE TEMPORARY TABLE TB_Tage TYPE=HEAP SELECT DISTINCT Datum FROM Tagesberichte AS TB WHERE Besucher_ID=10021 ' 020117 18:37:55 Error running query, slave aborted.

Re: strange replication problems
Benjamin Pflugmann writes: Hi. Does the error log of the master contain any error? Nothing at all in the master logs. Does the new log position make sense? Yes, the position is ok, and the slave gets the updates. Its just that strange error messages about dropped connections and 0-byte packets, and only on one of the slaves. It hangs always on the same offset. So it doesn't get forward at all. That's why I assume some priciple error. No, no, the log position changes as the updates are arriving from the master. There is some file called master.info in the database directory of the client. Could you redo the reload and delete that file after you stop the slave in the process. No, nothing, still the same message. Thanks for trying to track this, but I dont think that this is some principle problem, because I have a whole bunch of servers running replication, and running it for quite some time, they are all working fine, except for these messages on jus one slave. I suspect that this is either some really wierd quirk in replication process or I am overlooking something in the configuration of that particular server, even though I checked everything thousand times already.

Replication problems
We are looking for a solution to backing up a remote database, without using mysqldump, and replication seemed to offer the solution required. I set up the master/slave configurations on both the master and the slave exactly the way it was shown in the MySQL documentation (4.10.3 How To Set Up Replication), With some additional options as shown: MASTER my.cnf [mysqld] log-bin binlog-do-db=masterslave server-id=1 SLAVE my.cnf [mysqld] master-host=172.16.0.100 master-user=rep1 master-password='yesmaster' master-port=3306 server-id=2 replicate-do-db=masterslave I checked the slave status thinking it was telling me everything was fine mysql show slave status; | Master_Host | Master_User | Master_Port | Connect_retry | Log_File | Pos | Slave_Running | Replicate_do_db | Replicate_ignore_db | | 172.16.0.100 | rep1| 3306| 60 | | 4| Yes | masterslave | | I made some updates on the master, a couple of inserts and deletes.

Replication Problems
Hi Before enabling replication between two live machines, I've been doing some tests in the office between two similar machines. Everything appears to work well, as expected, except the command LOAD TABLE x FROM MASTER; This records an error on the screen ERROR 1188: Error From master: 'Access denied for user : ' and in mysql.err 010529 092358 fetch_nx_table: failed on create table Does anyone have an idea what might be causing this error ?

Re: Replication Problems
Hi Problem solved. After adding select permission (now file+select) to the replication user the command LOAD TABLE x FROM MASTER works perfectly. The only question is, why does this command need SELECT permission, whilst the rest of replication does not ?

Replication, problems with binlog-ignore-db
Hi, we use mysql with replication, all works fine. Now we wan't exclude some tables from the replication. I enter in my.cnf the line binlog-ignore-db = news (stop the master and restart the master after the change in my.cnf) After this, the master don't repliacted any databases, only the tables on the master db are updated. If i enter in mysql "show master status;" i get following result: +-+--+--+--+ | File| Position | Binlog_do_db | Binlog_ignore_db | +-+--+--+--+ | sumatra-bin.014 | 73 | | news | +-+--+--+--+ 1 row in set (0.01 sec) on thew slave i get: mysql show slave status; +-+-+-+---+-+-+---+-+-+++--+ | Master_Host | Master_User | Master_Port | Connect_retry | Log_File| Pos | Slave_Running | Replicate_do_db | Replicate_ignore_db | Last_errno | Last_error | Skip_counter | +-+-+-+---+-+-+---+-+-+++--+ | sumatra | blah| 3306| 60| sumatra-bin.014 | 73 | Yes | | news| 0 || 0 | +-+-+-+---+-+-+---+-+-+++--+ 1 row in set (0.00 sec) which each time has the same position number (on Master and SLave), when i enter the above statement I don't find something about souch a Problem in the manual. I use mysql Version 3.23.36 on Sun Solaris 2.6 Master configuration : log-bin server-id = 1 binlog-ignore-db = news Slave confguration: master-host=sumatra master-user=blah master-password=blah master-port=3306 server-id=2 Thank for your help Dani Daniel Tschanz Phone: +41 32 344 86 00 Rolotec AG Direct: +41 32 344 86 42 Gottstattstrasse 24, Postfach 8 Fax:+41 32 344 86 86 2500 Biel 8 mailto: [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

inserts with now() resulting in replication-problems
My Replication-Slave crashed a few days ago with an error in the error-log saying something like "duplicate primary key processing query "INSERT INTO testtable (time,name,number) VALUES (NOW(),'Hello',10)" testtable's primary key was (time,name) time: datetime name: varchar number: int What I was wondering after that: I do a "INSERT INTO testtable (time,name,number) VALUES (NOW(),'Hello',10) on the master. Then I do the *same* query again 1 Minute later. No Problem, since time has passed and NOW() is now different, so i do not have a duplictae key. If the Slave gets out of sync (loses the connection to the server), connects again and tries to catch up, it processes those two queries *within one second* which would result in an duplicate primary key on the slave. The Slave would abort with an error and the replication would stop. Is that right or did I misunderstand the concept? I changed the query to REPLACE instead of INSERT which is, in this case, fine with me, but is it possible to tell mysql to ignore such problems and keep the Replication up? I'd like to make the server send be a mail or SMS on my mobile phone if that happens. So if I could make the slave keep on replicating but write a line into a logfile like "serious-errors.log". I could then make some shell-script send me a mail... i'm running mysql 3.23.28-gamma on debian linux on Athlon-PCs. thanks for any explaination!

Just seems wrong to me, but what do I know ;-) - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
