A bank uses an online system to handle currency transactions, sent via MQ messaging. To avoid multiple database lookups to obtain the latest currency exchange rates, the rates are loaded into shared variables the first time the flow is executed. Periodic updates to the shared variables are made using a control message. As the volume of transactions increases, it is realized that a single instance of the flow can no longer cope, and so the solution developer is asked to investigate ways to increase throughput. How can the solution developer increase the message throughput?

• A.  Deploy the flow to a second broker and use MQ Clustering to redistribute these messages.
• B.  Deploy the flow to multiple execution groups.
• C.  Deploy multiple instances of the flow in different schemas.
• D.  Define multiple instances of the flow on the BAR file.

A solution developer has been informed of a problem with a message flow. Based on the error given, the problem seems to occur in ESQL code. The solution developer determines the need to debug the code. How does the solution developer set a breakpoint in the ESQL code?

• A.  1. Double click JavaCompute node
  2.Find code breakpoint location
  3.Left click margin of code window beside this location
  4.Choose Add Breakpoint
• B.  1. Double click Compute node
  2.Find code breakpoint location
  3.Right click left margin of code window beside this location
  4.Choose Add Breakpoint
• C.  1. Right click Compute node
  2.Choose open ESQL
  3.Set breakpoint on right hand side margin
  4.Choose Debug
• D.  1. Right click message flow
  2.Set breakpoint in appropriate location
  3.Redeploy flow

A solution developer needs to deploy a message flow initially in "Stopped" state. How must the solution developer achieve this?

• A.  Set the Start Mode property on the broker archive BAR file to "Stopped" status
• B.  Use the mqsistopmsgflow command to stop the message flows once they have been deployed.
• C.  Set the Start Mode property on the broker archive BAR file to "Maintained" status
• D.  Set the Start Mode property on the broker archive BAR file to "Manual" status

A company has implemented the following message flow to process orders received:

The ORDERS.IN node has the Transaction mode set to Yes.
When a failure occurs in the CalculatePrice node it is noticed that the database updates performed in the UpdateOrderDB node are not rolled back. How should the solution developer modify the flow in order to rollback the database updates in the event of a failure?

• A.  Set the Throw exception on database error property on UpdateOrderDB.
• B.  Add a Throw node following ORDER.ERROR.
• C.  Change the Transaction mode of ORDERS.IN to Automatic.
• D.  Insert a TryCatch node between UpdateOrderDB and CreateShippingInfo to handle the error.

To create a message definition, a solution developer has performed the following steps: 1.Create a new message set 2.Create a new message definition file 3.Add a Tagged/Delimited String (TDS) physical format to the message set 4.Import a COBOL copybook 5.Add a Custom Wire Formats (CWF) physical format to the message set 6.Import a C header file Which of the following is true?

• A.  The length of the fields on the CWF format in the COBOL message definition are not set.
• B.  The message definition file created in step 2 contains no logical definitions.
• C.  The message definition file created in step 2 does not support any physical formats.
• D.  The length of the fields on the TDS format in the C message definition are not set.
