| PCM currently does not provide a server failover functionality.
There are customers out there who have implemented some form of
"failover" by putting other applications in place, such as
shadowing. We are currently in the process of defining and
designing a failover functionality for the next release of PCM.
If you have any suggestions/requirements, please send me mail.
You can also post it here for general discussion.
Customers who have implemented partial failover do the following:
- shadow or copy over the PCM datasets (config db, etc) to a
secondary site also running a PCM server
- use the secondary server to monitor the primary PCM server.
- action routine set up so if failure is detected on the primary
server, the secondary server looks at the configuration database
(from the shadowing/copying) and re-establishes connections
to those nodes.
What's not covered in this scenario that we are still trying to
address are:
- licensing: the secondary server now has to have the same
set of licenses as the primary
- return of controls to the primary server when it comes back
up.
