How to setup openPDC on a clustered environment?

Mar 30, 2011 at 3:32 PM

Is there a guideline on how to setup openPDC on a clustered environment for both "fail over" and "load balanced" configurations?


Thanks in advance.

We haven't developed a guide - but there is some text in the FAQ.

We normally deploy a highly available openPDC system just using standard Windows clustering technologies.

The simple case is a fail-over cluster where two boxes are up and running, both having the openPDC installed with the same configuration.

One box is assumed to be "Active" the other is consider to "Stand-by".

Windows cluster can fail back and forth between the boxes as needed, making the stand-by active and the active stand-by.

The cluster will automatically start/stop the openPDC service on the active server as needed.

The load balanced cluster is similar, but all instances are active - this mode requires much more "device level" configuration in order to work.

We do have some "scale-out" documentation for creating a distributed hive of historians to be able to stay ahead of an archive load:

Hope that helps!
