A database warehousing application is beginning to experience decreases in its message
throughput, but messages are still being processed. The application is required to log each
transaction to the database warehouse prior to sending the transaction downstream for
processing. The application also recently scaled up to process larger batches of updates.
What is a possible cause for the performance degradation being experienced by this application?

A.
The MQPUT calls need to be recompiled to use 64bit memory buffering

B.
The space allocated for queue manager logs needs logs be increased

C.
The queue sizes need to be increased to handle the larger batches of message

D.
The queue manager needs to be modified to use the high message throughput mode.
