You work as a database administrator for Certkiller .com. Users in the Certkiller PROD database complain about the slow response when accessing the database. In the Active Session Waiting： Configuration page you find that the majority of the wait time is for the redo log buffer.Further investigation using the Run Queue graph and operating system tools reveals that the redo log files are on the same disks， and that the disk I/O for the redo log files is the reason for the performance degradation. Which two actions would you take to gain performance？（）A、Increase the size of redo log filesB、Increase the size of redo log bufferC、Increase the number of redo log filesD、Place the redo log files on a separate diskE、Decrease the number of redo log groups to twoF、Increate the number Log Writer （LGWR） process

Why can setting too low a value for the FAST_START_MTTR_TARGET parameter reduce your overall database performance？（）A、Data blocks have to be written more frequently by DBWR. B、Redo blocks have to be written more frequently by LGWR. C、You need to substantially increase the size of your database buffer cache to hold the additional checkpoint records. D、You need to substantially increase the size of your redo buffer cache to hold the additional checkpoint records.
