Yesterday, an Exadata storage server flashdisk entered the poor performance state.This flashdisk os used by flashcache and has a griddisk which is a member of a normal redundancy diskgroup.Identify the six steps you must perform to replace flashdisk.
You recently upgraded your Exadata image to the latest release; previously you were using 11.2.0.3.At the same time, you decide to address some performance problems as follows:You noticed increased latency for the database log writer, especially during the quarterly battery learn cycle on the cells.You have complaints of erratic performance from certain write-intensive applications.Which two actions could improve performance in these areas?
Which two statements are true about the use of direct path loads when selecting from external tables in a database on a Database Machine?
Your customer wants you to partition the database and storage grids in his X3-2 full rack, creating database clusters and two storage grids.One cluster will be used for production and should consist of 6 databases servers and 11 cells from the first storage grid.The other cluster will be used for test and development, and should consist of 2 database servers and 3 cells from the second storage grid.The storage must be partitioned so that the cells are visible only to the appropriate database servers based on the description above.What must be done to achieve this?
Which three statements are true about the initial storage configuration after the standard deployment of a new database Machine?
To troubleshoot a possible hardware problem, you consider moving all disk drives from one Exadata storage server to a replacement chassis.You must contain storage availability while performing task.The Exadata storage server is an X3-8 Database Machine and storage grid is not partitioned.Which two factors would prevent you from moving the disks from one Exadata storage server to another one?
