Oracle10g Grid Computing with RAC
Chapter 12 - RAC Design Considerations

Tablespace Design in Real Application Clusters

  • Tables and indexes that are mostly READ or READ-ONLY and infrequently modified.

The following criteria must also be considered for separating database objects into tablespaces:

  • Tables should be separated from indexes.

  • Assign read-only tables to READ-ONLY tablespaces.

  • Group smaller reference tables in the same tablespace.

Using this strategy to group objects into tablespaces will improve the performance of Oracle's dynamic resource mastering. Oracle’s "dynamic resource re-mastering by datafiles" algorithm re-distributes GCS resources to the instance where they are needed most. This re-mastering strategy is designed to improve resource operation’s efficiency. Oracle re-masters cache blocks to the instance with which the cache blocks are most closely associated based on historical access patterns. As a result, resource operations, after re-mastering, require minimal communication with remote instances through the GES and GCS.

Extent Management and Locally Managed Tablespaces

Allocating and de-allocating extents are expensive operations that should be minimized. Most of these operations in Real Application Clusters require inter-instance coordination. Keep in mind that a high rate of extent management operations can adversely affect performance in Real Application Clusters environments more than in single instance environments. This is especially true for dictionary-managed tablespaces.
