This section summarizes new features and functionality of TimesTen Release 18.1 that are documented in this guide, providing links into the guide for more information.
You can enable Transport Layer Security (TLS) to provide a more secure network communication for all replication agent communication. See "Replication agents" for more details. Also, you can see whether the TRANSMITTER and RECEIVER threads have been configured for TLS with ttRepAdmin -showstatus. See "TRANSMITTER thread status fields" and "RECEIVER thread status fields" for details.
You can use the Preallocate attribute to ensure that there is sufficient space for a new database when using the ttRepAdmin -duplicate command. If enabled, then TimesTen preallocates file system space for the database checkpoint files for the new database during the duplicate. See "Duplicating a database" and "Duplicating a master database to a subscriber" for more information.
TimesTen Replication features are available with TimesTen Classic or TimesTen Cache and is supported on multiple platforms. See the Oracle TimesTen In-Memory Database Release Notes (README.html) in your installation directory for specific platform versions supported by TimesTen.
In the past, you could use either automatic parallel replication (with or without commit dependencies) or user-defined parallel replication to manually divide work across different tracks. In this release, you can only use automatic parallel replication; user-defined parallel replication is not supported. See "Configuring parallel replication" for details.
Added instructions on how to modify connection attributes, such as PermSize, when using Oracle Clusterware. See "Modifying connection attribute values" for details.
Expanded the instructions for when you need to perform host or network maintenance when using Oracle Clusterware. See "Performing host or network maintenance" for details.
