You can achieve high availability for the service component of the adapter by running multiple service components as members of a distributed queue group. High availability is typically not a requirement for the interceptor component.
To configure highly available adapter instances, the COM server must be installed on multiple machines, and each of those machines should run service instances that have been configured using an RVCMQ session.
The TIBCO Rendezvous daemon process delivers a message to only one service instance. Therefore, if a service
instance goes down, any other instance that is running will receive and process the message. Also, if a service instance is busy processing a message, the TIBCO Rendezvous daemon process will assign the task to another service instance.
To achieve high availability in service components:
Import Metadata
option on the Import Schema
tab, in TIBCO Designer. The Import Schema
tab is available when you select the Advanced Services
folder in the project panel.Make sure that you use RVCMQ sessions in the configuration. Run the repository as a remote server.
For more information on configuring the RVCMQ sessions for the service instance of the adapter, see Configuring the Adapter for Load Balancing Using RVCMQ.
