IBM has a new availability solution, GDPS active-active continuous availability (GDPS/A-A), that offers an unlimited distance between data centers, cross-site workload monitoring, automated workload balancing, and recovery time objectives measured in seconds. I have a few highlights here. Full details can be found in IBM announcement letter 611-023.
- The first configuration available from GDPS/A-A is Active/Standby. As per the announce, IBM intends to deliver more over time. For example, an Active/Query configuration.
- To keep data in sync across sites, GDPS/A-A takes advantage of IBM's Q Replication for DB2 and a new IBM data replication product for IMS called InfoSphere IMS Replication for z/OS. A video here on ChannelDB2 shows how active-active replication works with Q Replication.
Health and performance monitoring is done through the Tivoli Enterprise Portal (TEP). I have a screenshot below. The image's first bullet shows where Active-Active information appears in the TEP navigation tree. The second bullet shows a launch point you can configure for
the Q Replication Dashboard
. The Dashboard gives you a way to drill down into health and performance details for Q Replication.
That's it for this post... just enough to whet your appetite :)
