Cache Tables

Cache Tables

The Data Object Cache Manager is the component of the Data Integration Service that creates and manages cache tables in a relational database.
You can use the following database types to store data object cache tables:
  • IBM DB2
  • Microsoft SQL Server
  • Oracle
After the database administrator sets up the data object cache database, use the Administrator tool to create a connection to the database. Then, you configure the Data Integration Service to use the cache database connection.
When data object caching is enabled, the Data Object Cache Manager creates a cache table when you start the application that contains the logical data object or virtual table. It creates one table in the cache database for each cached logical data object or virtual table in an application. The Data Object Cache Manager uses a prefix of
CACHE
to name each table.
Objects within an application share cache tables, but objects in different applications do not. If one logical data object or virtual table is used in multiple applications, the Data Object Cache Manager creates a separate cache table for each instance of the object.
