IBM Assessment: IBM WebSphere Process Server V7.0, Deployment 認定 A2180-608 試験問題:

1. A business integration application makes use of a non-interruptible business process which is invoked synchronously to update a backend SAP application and a data warehouse deployed on the DB2 database. Under peak loads, the business process performs poorly. The deployment professional is approached to fine tune the resources for better performance. What should be the appropriate tuning settings?

A) Increase the Java heap size but keep it low enough to avoid heap swapping.
B) Replace the DB2 database data store for the business process with file store.
C) Increase the sib.msgstore.discardableDataBufferSize default value to hold the data for which the quality of service attribute is best effort non-persistent of the business process.
D) Reduce the number of transaction boundaries within the business process and try to use parallel execution paths.
E) Increase the number of connections in the connection pool of the JDBC data source to connect to DB2 database.

2. A company wants to provide a new application prototype to any client to process their data. The intention is to start with a simple management system that provides a service to handle electronic contact requests. After a first evaluation of the solution, it is decided to use a WebSphere JCA adapter for e-Mail. The data will be processed by secured downstream SCA components once the data is sent to the adapter. What should be done to integrate the adapter solution in a secured WebSphere Process Server environment?

A) No action is required. WebSphere JCA adapters do not provide any authentication or authorization mechanism for inbound and outbound operations.
B) Consult the e-Mail service provider regarding the communication protocol. Secure the connection between the adapter and the service provider using SSL or similar protocols.
C) Advise the development team to enhance the service interface to retrieve customer specific information (e.g. user name and password). Each request sent to the adapter must be authorized for processing first.
D) Advise the development team to configure the security identity on all components connected with the adapter. Deploy the application and map the security identity.

3. In a clustered WebSphere Process Server (WPS) V7.0.0 environment, a company has migrated several long running business processes from earlier V6.x versions. An application performance issue which was identified in earlier versions was resolved by adjusting the maximum concurrent endpoints parameter of the BPEInternalActivationSpec of the Message Driven Bean (MDB) based on the peak load. However, the long running business processes do not perform as well as before. In spite of adopting similar settings, what has happened in the new WebSphere Process Server V7.0.0 environment and what are the appropriate tuning settings?

A) In WPS V7.0.0, the default for business process navigation is modified to utilize the advanced performance optimizations feature that leverages work manager based navigation. Accordingly, adjust the BPENavigationWorkManager message pool size and the InterTransactionCache size to accommodate the maximum concurrent incoming requests.
B) Modify the JMS connection factory BPECFC connection pool size to number of threads in the BPEInternalActivationSpec plus 10%. This is the required setting in WPS V7.0.0 used when work manager based navigation is enabled.
C) Modify the sib.msgstore.discardableDataBufferSize and sib.msgstore.cachedDataBufferSizeCachedDataBufferSize for optimal messaging engine (ME) performance.
D) WPS V7.0.0 fix pack one must be installed to enable optimization introduced by the Business Object (BO) Runtime Framework.

4. A highly available WebSphere Process Server clustered environment comprises of cluster1 with two members, clusterMemberA and clusterMemberB. cluster1 has been added as a member of a bus. The two cluster members host a message producer application, App1, and a message consumer application App2 which needs to consume messages produced by App1. App2 must receive messages in a sequential manner maintaining the order of message delivery. During peak load, the clusterMemberA is most active taking significant performance impact while clusterMemberB is almost idle and is only experiencing about 25% of the overall activity. Identify the steps the deployment professional should take to reconfigure the messaging infrastructure so that the load is balanced more evenly among both cluster members of cluster1.

A) Create another server with messaging only capabilities. Add this server as a bus member and detach the cluster1 from the bus.
B) Create an additional messaging engine on cluster1 so that each cluster member hosts an active messaging engine for an even load distribution.
C) Create a secondary two member cluster cluster2 with messaging only capabilities. Add cluster2 as a bus member and detach the cluster1 from the bus.
D) Create a secondary two member cluster cluster2 with messaging only capabilities. Add cluster2 as a bus member and create an additional active message engine on cluster2 and detach cluster1 from the bus .

5. A deployment professional is asked to investigate a failure in a business process. However, the specific process instance being investigated is still running. After close examination, one of the activities of the process instance is stopped. What action should the deployment professional take to resolve this issue so that the current process navigation can continue?

A) Examine the variables of the stopped activity and update the values as necessary, and save the settings.
B) Change Continue On Error setting of the process template to no but make sure this setting is overridden at the activity scope to a value of yes.
C) Change Continue On Error setting of the process template to yes and ensure this setting is inherited at the activity scope.
D) Set the expiration for the stopped activity so that after a specified interval the activity terminates and the process can continue.
