If you want TIBCO® Adapter for SAP Components to scale (add new Engines) automatically, you can define rules that add or remove TIBCO Silver
® Fabric engines based on engine statistics Adapter for SAP component statistics.
Statistics consist of engine and machine measures that are independent of TIBCO® Adapter for SAP and any other statistical information gathered from the Adapter for SAP via TIBCO Hawk ® when that is applicable.
The Archives tab defines what archive is added or removed according to the rules you define in the other tabs.
Use the Add icon at the right of the column heading row to add one or more archives (process instances) to be scaled up or down in your stack.
Select the Adapter for SAP component that was used to upload the application archive file and use the Archive Names field to specify what archive is subject to the rules you set using the other tabs of the Archive Scaling Rule Editor.
Use the Add Archive Conditions tab and click the
Add icon to the right of the column heading row to create and define a new Add Archive rule.
You can define more than one rule. With more than one rule, set the Satisfies field to specify whether all rules must be satisfied or whether any one rule can be satisfied to trigger addition of a new archive instance.
The Remove Archive Conditions tab enables you to release computing resources and remove unused or idle Component Archives or process instances to scale down your Component Archives just as you scaled them up according to conditions you define on usage statistics.
With the Target Component Conditions tab, you can restrict the start of new Archive instances to those machines that have the same set of resources that you choose. Set a rule or several rules with statistics, operators, and values as you would on the Add Archive Conditions tab and further restrict where the new Archive instances can start depending on component Instances that have:
Same Component: works all the time for Component Archive scaling.
From the set of Components: works only if your Component Archive is compatible with the set of components present. For example an Adapter for SAP archive can scale on an Adapter Component.
Same Component Type: the process archive has the possibility of being scaled up on different versions of the product
Same Enabler: components that require a specific enabler should use this option.
Same Middleware Version: this selection ensures that the Component Archive runs on machines with the appropriate middle ware: TIBCO Adapter for SAP, TIBCO TRA, TIBCO Hawk, etc.
Same Enabler and Middleware Version: this selection ensures that your Component Archive scales up successfully, but it is the least restrictive of the target component conditions. .
