Anybody have experience of running UC4 OM in high availability mode? If so, how does it compare?


Were your findings in a test or live environment?

Hi Mrs Broflovski

I have experience running UC4 OM in high availability mode in a production environment (at a large investment bank). The UC4 OM architecture compares very favourably with the HA architecture of other workload automation products. The architecture also lends itself to processing high volumes of jobs with virtually no latency.

With regard to HA - The resiliency of your scheduling database is typically left in the hands of the DBAs (who will leverage the resiliency features of Oracle, DB2 or MS SQL). When it comes to the UC4 OM server processes (Communication Processes , Work Processes and the Dialog Work Processes) you run these processes on multiple servers so that scheduling and user access continues without interruption when any individual server fails.

Obviously every product has it's advantages and disadvantages, for UC4 OM its High Availability architecture is an advantage.

Cheers
