Which statement about Allocation Units is incorrect?

  1. Every Oracle ASM disk is divided into allocation units (AUs)
  2. An AU is the fundamental unit of allocation within a disk group,
  3. A file extent consists of one or more AUs.
  4. The au size disk group attribute can have the following values; 1, 8, 16, 32, 64, or 128 MB.

Answer(s): D

Explanation:

When you create a disk group, you can set the Oracle ASM allocation unit size with the AU_SIZE disk group attribute. The values can be 1, 2, 4, 8, 16, 32, or 64 MB, depending on the specific disk group compatibility level. Larger AU sizes typically provide performance advantages for data warehouse applications that use large sequential reads. Reference:

  1. Server pools logically apportion a cluster into groups of servers offering database or application services.
  2. MAX_SIZE and importance are valid server pool attributes,
  3. You can configure each server pool with a maximum size. The minimum size cannot be configured.
  4. Oracle Clusterware manages availability between server pools automatically. It cannot be
    manually configured.
  5. Servers are assigned to server pools by name.

Answer(s): A,D

Explanation:

Server pools logically apportion a cluster into groups of servers offering database or application services. Server pool properties control the scalability and availability of those databases and applications. You can configure each server pool with a minimum and maximum size, which determines scalability. Oracle Clusterware manages availability between server pools, and you can further regulate availability by configuring the importance value of individual server pools.
