What's New

This preface summarizes the new features of Oracle TimesTen In-Memory Database release 11.2.2 that are documented in this guide. It provides links to more information.

New features in Release 11.2.2.4.0

You can now specify an alias or the IP address of the network interface when you want to use a specific local or remote network interface over which database duplication occurs. For details, see "Duplicating a database".

New features in Release 11.2.2.2.0

• By default, replication is performed with a single thread. You can increase your performance by configuring parallel replication, which configures multiple threads for sending updates from the source database to the target database and for applying the updates on the target database.

  There are two types of parallel replication: automatic and user-defined. In this release, automatic parallel replication is introduced. For more information, see "Configuring parallel replication".

New features in Release 11.2.2.1.0

• You have additional control over TimesTen application behavior when Oracle Clusterware is managing a TimesTen active standby pair. The AppFailureInterval, AppRestartAttempts and AppUptimeThreshold Clusterware attributes are new. See "Implementing application failover".

New features in Release 11.2.2.0.0

• Durable commit behavior has changed. See "DURABLE COMMIT" for active standby pairs and "DURABLE COMMIT" for other replication schemes.

• LOB columns can be replicated. See "Table requirements and restrictions for active standby pairs" and "Table requirements and restrictions for replication schemes".

• TimesTen provides in-memory columnar compression. However, you cannot replicate tables with compressed columns. This restriction is mentioned in "Table requirements and restrictions for active standby pairs" and "Table requirements and restrictions for replication schemes".
