An example of the syntax would be this line in the my.cnf file of your slave: replicate-rewrite-db="master_db->master_db_foo" Any statement on master_db would be replicated to the slave, but then executed on master_db_foo. So, for example: You execute 'update table1 set foo=4 where bar=2;' on the master_db on your replication master. The statement would get replicated down to the replication slave. When the slave is evaluating your replication rules, it will see that the statement should be rewritten to apply to the master_db_foo. Then 'update table1 set foo=4 where bar=2;' is executed on master_db_foo. Hope that helps, Dan

Re: --replicate-rewrite-db fails when attempting to drop a table
Hello. You should not use a cross database syntax for you queries. Instead of 'DROP TABLE `livedb`.`test_replication`' use use livedb; DROP TABLE test_replication Ian wrote: > Hi List, > > I have been asked to setup replication between two customers servers for one > particular > database, which I will call in this post 'livedb'. > > The customer also has a copy of this database on the slave which they use for > testing. > This copy does not contains the same data as the master and the customer > wants to > leave it this way, they therefore asked if it was possible to replicate to a > different database > name, e.g. livedb_backup. > > I suggested the use of the --replicate-rewrite-db option. > > When I set this up and tested it I decided to create a new table and then > drop it to make > sure it was working ok ( if it wasn't I didn't want to taint the existing > data ). > > I created a table called test_replication and it was promptly created on the > slave, but, > when I issued a DROP TABLE command the replication stopped and the follwing > error > was present in the .err file: > > 060117 15:25:22 Slave: Error 'Unknown table 'test_replication'' on query. > Default > database: 'livedb_backup'.

--replicate-rewrite-db fails when attempting to drop a table
Hi List, I have been asked to setup replication between two customers servers for one particular database, which I will call in this post 'livedb'. The customer also has a copy of this database on the slave which they use for testing. This copy does not contains the same data as the master and the customer wants to leave it this way, they therefore asked if it was possible to replicate to a different database name, e.g. livedb_backup. I suggested the use of the --replicate-rewrite-db option. When I set this up and tested it I decided to create a new table and then drop it to make sure it was working ok ( if it wasn't I didn't want to taint the existing data ). I created a table called test_replication and it was promptly created on the slave, but, when I issued a DROP TABLE command the replication stopped and the follwing error was present in the .err file: 060117 15:25:22 Slave: Error 'Unknown table 'test_replication'' on query. Default database: 'livedb_backup'. Query: 'DROP TABLE `livedb`.`test_replication`', Error_code: 1051 Both servers are Windows running version 4.0.26 ( one is win2k the other win2k3 ). Am I doing something wrong or is this a bug? Here is the relevant section of my.ini on the slave: --->8- [mysqld] basedir=D:/mysql datadir=D:/mysql/data set-variable=max_connections=300 log-bin server-id=20 log-error log-slow-queries log-slave-updates log-warnings replicate-do-db=livedb_backup replicate-rewrite-db=livedb->livedb_backup --->8- Thanks Ian -- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
replicate-rewrite-db
I have the same db on master and slave and I want to use replicate-rewrite-db to change the replicating name of this db on the slave. Slave my.cnf: --- [mysqld] datadir=/var/lib/mysql socket=/tmp/mysql.sock master-host=master.company.com master-user=repl master-password= master-port=3306 server-id=2 replicate-rewrite-db=mydb->slave_mydb skip-innodb [client] socket=/tmp/mysql.sock [mysql.server] user=mysql basedir=/var/lib [safe_mysqld] err-log=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid Master my.cnf --- [mysqld] log-bin server-id=1 socket=/tmp/mysql.sock [client] socket=/tmp/mysql.sock [mysql.server] user=mysql basedir=/var/lib [safe_mysqld] err-log=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid The slave seems to ignore replicate-rewrite-db option and tries to create an already existing db (as I said, same db names on master and slave), so I get an ERROR 1007: Can't create database 'mydb'. Database exists I put the replicate-rewrite-db option AFTER creating mydb on master, so the bin log already contains this action. Can this be the problem?

syntax problem with replicate-rewrite-db
Hi All, (sorry if this is a duplicate -- I don't think the original made it) Running mysql 3.23.53-max binary on a RedHat 7.2 based server. Replication is working fine, but I'm running into errors with the replicate-rewrite-db directive. Here's a snippet from my my.cnf file on the slave: master-port = 3306 replicate-rewrite-db=mysql->master_mysql When I try to start the instance, I get the following error in my log: 021118 14:30:56 mysqld started Bad syntax in replicate-rewrite-db - missing '->'! 021118 14:30:56 mysqld ended I've tried every possible combination of white space I could think of, and even cut and pasted the exact syntax from the documentation, and created tables with those names, yet I still get the same error, so it doesn't appear to be a problem specifically with replicating the mysql table. I've also tried mysql 3.23.52-max binary, and gotten the same thing, so it's definitely not a issue with a specific version of mysql... Can anyone help figure out how to get this working?

Hello (Post 2) Has anyone got replicate-rewrite-db (a my.cnf entry) to work. I have replication running fine, however the rewrite doesn't work. I just want to know whether I should persist or if there is something special people had to do to get it working. I have heard / read a few people saying that they couldn't get it to work.
