Which three statements are true about Automatic Hard Disk Scrubbing and repair on high-capacity storage servers in an X5 Database Machine?
You plan to migrate a database supporting an OLTP workload to your new X5 Database Machine.The current database instance supports a large number of short duration sessions and a very high volume of short transactions.Which three X5 Database Machine features can improve performance for this type of workload?
Your X6 Exadata Database Machine is running Oracle Database 12c, and has a large database with some very large tables supporting OLTP workloads.High-volume insert applications and high-volume update workloads access the same tables.You wish to compress these tables without causing unacceptable performance overheads to the OLTP workload.Which three are true regarding this requirement?
You plan to migrate a database supporting both DSS and OLTP workloads to your new X5 Database machine.The workloads contain many complex aggregating functions and expensive joins on large partitioned tables in the DSS workload and indexed access for OLTP workloads.Which three benefits accrue as a result of this migration?
You issued these commands to all Exadata Storage Servers in an X6 Exadata Database Machine using dcli: alter iormplan objective = low_latency alter iormplan activeThere are no database or category plans defined.You are encountering disk I/O performance problems at certain times, which vary by day and week.DSS and Batch workloads perform well some of the time.Further investigation shows that at times, the workloads are all OLTP I/Os, at other times all batch I/Os, and sometimes a bit of each.You wish to have disk I/O managed so that performance will be optimized for all workloads.Which statements would you issue to all Exadata Storage Servers to achieve this?
Which four are true about Exadata features?
