Hi Andreas,
with NDB, you have 3 types of node: SQL which is mysqld, Management
running ndb_mgmd and data running ndbmtd. SQL and Management can be on
the same physical host (cohosting) but you ideally need 2 for HA, the
ndb_mgmd process is very small and low on resources. Data nodes, for H
Hi Yves,
Ø NDB requires a minimum of 4 nodes for HA...
I understood that in NDB-Cluster the concept of „nodes” has nothing to do with
physical (or virtual) hosts but with running instances / processes. That’s at
least, what can be derived from

Hi Andreas,
NDB requires a minimum of 4 nodes for HA... 2x SQL/mgmnt nodes + 2x
data nodes. The SQL/mgmnt nodes could be your tomcat servers without
problem but the data nodes must be other physical servers.

No, not really. :-) I just want to avoid the overhead of DRBD for replication.
We have to get faster than that. :-)
As I already wrote. I'm evaluating two different approaches:

Hi!
I’m on the lookout for alternatives to our current MySQL “cluster”, which is an
Active/Standby solution with MySQL on DRBD.
With increasing customer demand for a faster failover, we want an
Active/Passive or even an Active/Active cluster.
Currently we run a Tomcat application, which works i
