Hi all,
Today i set up a circular replication between three nodes A,B C
successfully.
I expect whatever writes on A will propagated to B then Propagated to C
because the structure is like below :-
A - B - C - A
I created a sample table stag in test database in A and insert few records

I stand corrected and apologize. Numerous multi-master setup descriptions I've
read have said to set this (including the one linked in the original question).
However, as you said, the entry in the manual clearly says it defaults to 0.

Don't use circular replication with more than 2 servers. If one of your 3
crashes and cannot be recovered, you will have a nightmare on your hands to fix
the broken replication.

I've got an issue where two MySQL servers are in circular/multimaster

that GRANT statements issued on 6871 are replicated to 206871 and
I was reading the circular replication post on Onlamp.com, how they
achieve this master-master configuration. I was wondering if this will
always work out in a scenario. For example:

Node1 starts at time A, 5

Chain replication is fine as long as reading stale data from the last slave

The long story short is we use the fact that MySQL has the ability to
run the SQL thread and the IO thread of replication separately, and
control them individually.
I'm fairly green with replication, but I have a simple cron job that

Does anyone use circular replication with MySQL 4.x? For instance:
A to B
B to A
I know it's possible as long as you're carefull with your client
applications and the way they write/update the db. Just wondering if
anyone has had success or problems with this type of situation.
Thanks

If you are using InnoDB, then you do not need to stop server A to take a

I've had some brief discussion about this with other people on other lists
and have decided to move the conversation here, since there are far wiser
MySQL gurus here than I. Here's the scenario:
I want to have two (or more, but for now let's say two) db servers
running. These servers will have
tables.
It is not entirely clear wether replication will work with innodb
tables.
We're hoping to use MySQL 4.x
Can we build reliable, circular replication with innodb tables in MySQL?
We will have the application pick a single master node for any
particular table and/or database until all nodes

Hi,
We're doing something weird (what else is new). We're hoping to use
MySQL as the base of a distributed database
even/odd is a little limiting, what happens down the road when another
site needs to be added.
A better method might be to use a unique session ID for each client site
in combination with a
generated sequence ID see the white paper
