White Paper – Oracle VM Template for MySQL Enterprise Edition

A new white paper is available that steps you though the benefits and the use of the Oracle VM Template for MySQL Enterprise Edition (also see yesterday’s press announcement). Get the white paper here.

As a reminder Oracle Virtual Manager provides a way to add High Availability to your MySQL deployment (this is separate from MySQL Replication and MySQL Cluster).…

MySQL Cluster fault tolerance – impact of deployment decisions

MySQL Cluster is designed to be a High Availability, Fault Tolerant database where no single failure results in any loss of service.

This is however dependent on how the user chooses to architect the configuration – in terms of which nodes are placed on which physical hosts, and which physical resources each physical host is dependent on (for example if the two blades containing the data nodes making up a particular node group are cooled by the same fan then the failure of that fan could result in the loss of the whole database).…

MySQL Cluster – flexibility of replication

One of the better kept secrets about MySQL Cluster appears to be the flexibility available when setting up replication. Rather than being constrained to implementing a single replication scheme, you can mix and match approaches.

Just about every Cluster deployment will use synchronous replication between the data nodes within a node group to implement High Availability (HA) by making sure that at the point a transaction is committed, the new data is stored in at least 2 physical hosts.…
