GOAL:
Does Progress work on a Windows 2000 Cluster?
GOAL:
Is Progress supported on Windows 2000 Cluster?
FIX:
Progress is supported on Microsoft Windows Clusters.
The way clustering works with Windows is that there are two nodes (for example node A & node B), these share an external storage device (disk) which only one node has control of at a time. Both nodes have a their own physical IP address and computer name. The cluster service uses a Virtual IP address and Computer name. It is the virtual address which the client should reference, not the actual IP address
ame of each node. The cluster service can then direct client requests to the virtual node to the current physical node which is active. Therefore if failover does occur, the client still connects to the virtual node, which will then be pointing at node B.
A Progress database would use ProService to automatically stop and start each database in case of failover between the nodes. A failover object for the ProService could be created within the Cluster Administrator and this would be stopped on one node and started on the 2nd node.
Also the product Fathom High Availability Clusters is specifically for using Progress databases in a clustered environment.
