Question 100/180

In your organization, there are two key databases. One of them is used primarily for an online transaction processing (OLTP) application and is directly accessed by the users in a client/server configuration. The application must process an average of 4,000 small transactions per day. The users enter frequent queries on whose results they depend for completing their transactions. One of the SLA requirements is that any query or transaction processing in the OLTP system should not exceed 15 seconds.
The second database supports a decision support system (DSS) as well as batch report programs. It is accessed by client-side users, who submit ad hoc queries through SQL*Plus and by a browser-based,third party application that provides pooled connections for a large user base. The queries vary: some fetch only a few records, whereas others fetch and sort hundreds of records from several tables. As per the SLA specification the average turnaround time for a query on the DSS returning 10000 records should be 24 hours.
For both the systems, the number of users is not consistent and may vary from time to time.The management wants to ensure maximum resource usage is allocated for the OLTP processing.
Which two considerations should you give priority to when tuning these databases? (Choose two.)

A. Maximize throughput for batch processing.

B. Minimize response time for the decision support systems.

C. Minimize parallelism for the OLTP systems.

D. Maximize parallelism for the decision support systems.

E. Minimize the response time for OLTP users.
