Your database supports an online transaction processing (OLTP) workload on an SMP machine.

The database is stored in ASM.

Examine these initialization parameters.

Applications are update intensive using indexed access and modified blocks are written in batches by the DBWR process.

You notice a large number of free buffer waits and increase the size of the buffer cache, but eventually the same waits occur.

Which two actions would you recommend? (Choose two.)

Select all that apply.

• A

  decrease the size of the buffer cache

• B

  configure asynchronous I/O

• C

  modifying the ASM disk for the database to use high redundancy

• D

  configure multiple DBWn processes

• E

  configure I/O slaves for the DBWR process
