Administration Support for Older Hosts and Nodes
TIBCO ActiveMatrix Administration server supports hosts and nodes of versions prior to ActiveMatrix Service Grid 3.4.2.
ActiveMatrix Service Grid may support many solutions in a production environment. Upgrading to a newer version of the ActiveMatrix Service Grid may bring with it unique challenges. For that reason, some enterprises may be reluctant to upgrade their entire set of applications to the new version at once. Some businesses may choose to upgrade gradually, some may plan it in phases, and some may not upgrade their applications at all.
TIBCO ActiveMatrix Administrator can manage ActiveMatrix Service Grid Hosts, Nodes, and Applications running versions prior to ActiveMatrix Service Grid 3.4.3. With this, you can install the latest ActiveMatrix Service Grid version and continue to use and manage the existing ActiveMatrix environments.
In an enterprise, the hosts or nodes could have a version that is different from the ActiveMatrix Administrator that manages them. For example, in 3.4.1, ActiveMatrix Administrator can be upgraded to 3.4.2 while the host it manages could be running on an older version (3.4.0, 3.3.0, or 3.2.0) and they can still coexist.
When a runtime host is upgraded to 3.4.3, all the nodes managed by that host are also upgraded to 3.4.3. As a result, the host and the nodes it manages are in sync and run the same version of ActiveMatrix Service Grid.
Exceptions to Version Coexistence
As a rule, a Deployment Artifact Archive (DAA) can only be used with nodes whose version is greater than or equal to the TIBCO Business Studio - BPM Edition version used to create the DAA. For example, a DAA created by ActiveMatrix Service Grid 3.3.0 requires nodes running ActiveMatrix Service Grid 3.3.x or higher (for example, 3.4.x).
To find out the node version, you can use the
tibcohost.exe describeNodes
command or use the ActiveMatrix Administrator UI Nodes tab.
