distributed/clustered/redundant architecture

Is there any documentation or case study available online that elaborates further on the distributed/clustered solution?
Thanks in advance.

"Can Texis be used in a distributed/clustered/redundant architecture?
Yes, most of our larger customers have implemented some sort of redundancy strategy. The designs tend to vary based on many particulars including the size of the application, user load, frequency of update, etc.

There isn't as the solution chosen does depend on the specifics of the application.

Jonh,
The replication strategy suggested in the tutorial (http://www.thunderstone.com/texis/site/ ... eload.html) would require having several copies of the same database in order to facilitate load balancing. Replication of terabytes of data is not always the most cost effective solution.

Currently we mount large SAN volumes on Linux machines to store our databases. It is possible to share a single SAN volume by several machines with read/write access. If we could share a single database located on a SAN volume by several machines, that would be the Holy Grail for us. As far as I know, currently texis does not support such architecture. I've tried running texis queries in a similar environment. One of the machines encounters lock issues that has something to do with SYSLOCK.

Does Thunderstone product roadmap include implementation of something similar?
