Chapter 2 Creating a TIBCO Silver Fabric Enabler for Adapter for SAP Stack : Dependency Requirements

Dependency Requirements
Each TIBCO® Adapter for SAP Component, must have a component dependency set on one TIBCO Administrator Component. You must set this Component Dependency for each of your TIBCO® Adapter for SAP Components. Those components without defined Component Dependencies will not have enough information for proper publishing.
The TIBCO® Adapter for SAP Component must have the TIBCO Administrator configuration information so that it may publish, unpublish, and communicate with other components (if required) successfully. A connection is supported between theTIBCO® Adapter for SAP Component and one instance of the TIBCO Administrator Component. Connecting with more than one TIBCO Administrator Component is not supported. After setting the dependency, TIBCO® Adapter for SAP will start after TIBCO Administrator is up and running.
To set the dependency, follow these steps:
1.
During creation or edit of the TIBCO® Adapter for SAP Component, select Add/edit default rule settings from the Menu of the Component Wizard.
2.
Use the Add Rule pull down to select the Component Dependency option.
3.
In the Depend on field, select the name of the TIBCO Administrator component that runs inside your Stack.
If you run TIBCO Administrator in the Fault Tolerant mode, clear the Shutdown Dependency check box. Otherwise, all TIBCO® Adapter for SAP Components might stop if TIBCO Administrator stops working.
If the Administrator component was configured to "Use dependent EMS server" then that dependency must be set here as well.
When using a dependent TIBCO Enterprise Message Service server, the dependency should be set in the TIBCO Administrator component, which must also have a dependency on TIBCO EMS Server Component.
Shutdown Dependency
Establishes a requirement for the parent, specified in the Depend on field, to be active to keep the dependent component running. When selected, the stack stops component dependencies if the parent component becomes unresponsive.
If you use a Database domain, enabler for adapter for SAP continues to work. However, every change in TIBCO Administrator is not taken into account by Enabler for Adapter for SAP even after exporting the changes.
If you run TIBCO Enterprise Administrator in the Fault Tolerant mode, clear the Shutdown Dependency check box. Otherwise, all BusinessWorks components stop if TIBCO Enterprise Administrator stops working.
Ordered Shutdown
Ordered Shutdown provides for a logical, sequential shutdown so that dependent components are shut down first. Ordered shutdown is especially important when the domain is hosted using a file structure instead of a dependent database. When you have an administrative component that uses an external database, the order of shutdown is less important.
Restart Component for new rules
If new rules are defined for a component that has already been deployed, it must be restarted for the new changes to be applied. If you wish to manually restart components later to propagate changes leave this box cleared.
Pack by Host
Check the Pack by Host check box to specify that dependent components must run on the same host.
For more information on all these setting, refer TIBCO Silver Fabric User’s Guide.
