Re: replication - queries out of order or dropped?
Hi Martin, Replication definitely does not ignore CREATE DATABASE all the time, just every now and then :) I had 93 databases that made it through replication, and the 94th failed. There aren't any binlog-ignore-db paramaters. I've dumped the binlog out, and CREATE DATABASE did make it into the log, and the slave did make it past that point without creating the database. Is there any reason to think that replication is more reliable in the 4.0 series?

Re: replication - queries out of order or dropped?
I've been doing a lot of poking around... the actual database is what didn't get created. The CREATE DATABASE statement did make it into the log file, and the slave got past that point without ever creating the database. Go figure...

replication - queries out of order or dropped?
Hi All, Trying my best to maintain some production servers running mysql-max-3.23.53a-pc-linux-gnu-i686 with one master and one slave. We keep having issues where we create a new table on the master, and a short while later the slave will crash because it starts trying to perform queries which insert into the new table, but it looks as if the query to create the table hasn't been executed yet (ie the table doesn't yet exist on the slave). I've got three pairs of master/slave servers, and this is happenning on all of them. My experience is that I can brute-force something such as setting the skip count to some positive integer, etc. etc., but that's only a hack, and doesn't get around the big problem here which is that somehow the queries are seemingly getting either skipped or out-of-order. Any help here? My management is getting quite upset about this. We're not using the slaves for anything at present, but they are meant to be a disaster recovery option. Right now they're worthless... Thanks in advance, David Nedved here is the output of show slave status on a currently broken slave: (sure enough the table exists on the master, but not on the slave) Welcome to the MySQL monitor.
