Supported Cache Features in TimesTen Scaleout

The following features are supported for cache operations in TimesTen Scaleout:

• Using Passthrough

• Using Oracle RAC

Using Passthrough

When an application issues statements on a TimesTen connection, the statement runs in the TimesTen database or passes through to run in the Oracle database. Whether the statement runs in the TimesTen or Oracle database depends on the composition of the statement and the setting of the PassThrough connection attribute.

You can set the PassThrough connection attribute to control which statements run locally in TimesTen and which are to be redirected to run in the Oracle database.

See Setting a Passthrough Level in Oracle TimesTen In-Memory Database Cache Guide.

Using Oracle RAC

Oracle RAC enables multiple Oracle database instances to access one Oracle database with shared resources, including all data files, control files, PFILEs and redo log files that reside on cluster-aware shared disks. Oracle RAC handles read/write consistency and load balancing while providing high availability. See Using Cache in an Oracle RAC Environment in Oracle TimesTen In-Memory Database Cache Guide.
