Open Source Database Clusters?
grugruto asks: "A lot of open source solutions are available to scale web sites with clusters but what about databases? I can't afford an Oracle RAC license but can I have something more reliable and fault tolerant than my single Postgres box? I have seen this recent article that looks promising for open source solutions. Do anyone have experiences with clusters of MySQL , Postgres-R, C-JDBC or other solutions? How does it compare to commercial products?"
Open Sores software will never have the stabilty and features of its commercial counterparts - To do so would go against the whole point of open sorse (Copy a commercial software (via source or functionality), and do a 1/2 arse job of it).
Use Oracle.
Funny, it looks like many don't even know what a cluster is. Some even mention replication as some sort of clustering. :)
The only real clustering technology to speak of is OpenVMS clusters.
