Tibco BusinessWork ActiveMatrix for dummies ...

I had a hard time understanding the Tibco BusinessWorks ActiveMatrix (Tibco BW AMX for short) proposal. Thanks to Thomas Been from Tibco France, things are a little clearer now.

Which Tibco BW do you want?

With version 5.7 of the tool you know have the choice between two options:
  • AMX foundation based = Tibco BW AMX = BusinessWorks services are deployed in Tibco AMX foundation. The administration tool is then Tibco AMX Administrator.
  • TRA based = Tibco BW Standalone = BusinessWorks services are deployed in TRA. The administration tool is then Tibco Administrator.

Governance Cockpit = TIBCO AMX Administrator

TIBCO AMX Administrator provides configuration, deployments et monitoring services. This creates then a unique cockpit (common environment) for administrating the SOA platform, the Runtime components, and the runtime governance (UDDI directory, policy Mgt, SLA management).

TIBCO AMX Administrator hosts and offers access to AMX governance services like:
  • AMX Runtime UDDI Server
  • AMX Policy Manager
  • AMX Service Performance Manager
But it also enrich its offer with:
  • Different views for managing the service lifecycle. The same service deployed on several nodes will have all its metrics aggregated and the different configurations will be easily available.
  • Shared Resources will be declared and managed in one place.
  • Logging will be common to all AMX services. The common Logging framework offers then a unique logging for a service deployed on several nodes (if grid is activated)
TIBCO AMX Administrator was designed to be flexible and is a kind of service container. More services will be added in the future for different types of stakeholders (not only administrator).

SLA Management = Service Performance Manager (SPM)

AMX Service Performance Manager is a tool to manage SLA. So you can:
  • Define SLA et rules around them (violation rules, and also service usage conditions)
  • Actions to be executed when rules are triggered (re-deploy a service on another node, etc.).
SPM works with both Tibco BW AMX and Tibco BW Standalone and offers deployment of services in both Tibco BW AMX (deploying in different nodes) or Tibco BW standalone (will launch another instance of the TRA).
Deploying BW services in AMX Foundation is included for free in any BW client licenses. But this is not including SPM that requires new license(s).

How to move from Tibco BW Standalone to Tibco BW AMX?

Two options :
  • Archive level. Simple re-deploy, without changing the archive, in AMX foundation. Tibco Engineering Team did take care about the compatibility. In that case, TIBCO AMX Administrator provides the same archive information that in TIBCO Administrator.
  • SCA Migration. You have to open the archive in Tibco BusinessStudio, make some modifications to create an SCA valid diagram. Then you can benefit from transversal functionalities of AMX like:

    • Shared Resources usage
    • Total Visibility in TIBCO AMX Administrator, especially in the service view
    • Hosted services Invocation on the Grid (if grid is used)
    • Common logging framework usage
    • Direct integration with SPM and PM
    • The archive can not contain processes that are « not services » (files, etc).

Recommended Upgrade Process

1/ Migrate the infrastructure first and deploy previously made Tibco service archives on it.
2/ Train your teams to SCA and re-packages your Tibco projects as SCA components.
3/ Think internal Grid or go to the Cloud with Tibco Silver.
