Question
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?
Options
- ADefine multiple instances of the flow on the BAR file.
- BDeploy the flow to multiple execution groups.
- CDeploy multiple instances of the flow in different schemas.
- DDeploy the flow to a second broker and use MQ Clustering to redistribute these messages.
