Adapter Service Transaction Processing
The following diagram illustrates how webMethods Adapter for IBM Power processes adapter services at run time.
1. An Integration Server client, typically using a flow or Java service, invokes webMethods Adapter for IBM Power service on Integration Server to perform an operation on the IBM Power system resource.
You configured the adapter service earlier using Designer.
2. The adapter service gets a connection from the service's connection pool. Adapter connections contain connection information for the IBM Power system.
3. The adapter service uses the IBM Toolbox for Java to connect to the IBM Power system.
You created and enabled the adapter connection earlier using Integration Server Administrator.
4. Adapter services perform various operations such as reading from and writing to dataqueues, calling a command or program.
5. Depending on the adapter service type, such as a Read DataQueue service, the adapter service may return data to Integration Server.

If the operation is successful, the service returns the output from the service's operation, if applicable.

If the operation is unsuccessful, the service returns an error such as an AdapterException. If IBM Power system throws an exception while performing the adapter service's operation, the adapter passes the exception to the
Integration Server logs.
