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.
The TimesTen JDBC driver implements the JDBC 4.2 API (Java 8) and is certified to work with Java 8, 9, and 10 runtime environments (JRE).
This includes support for standard REF CURSORs, large update counts, SQLType, and DatabaseMetaData enhancements. (See "Working with REF CURSORs".)
TimesTen Scaleout includes a new client routing API that enables Java client applications to route connections to a grid element based on the key value for a hash distribution key. This feature enables the client application to connect to the element that stores the row with the specified key value, avoiding unnecessary communication between the element storing the row and the element connected to your application. For more information, see "Client routing in TimesTen Scaleout".
The TimesTen JDBC driver implements the JDBC 4.1 API (Java 7) and is certified to work with Java 7 and Java 8 runtime environments (JRE).
There are new error codes for manual retry after transient errors. TimesTen automatically resolves most transient errors (which is particularly important for TimesTen Scaleout), but if your application detects certain error codes, it is suggested to retry the current transaction or most recent API call, as applicable. Refer to "Retrying after transient errors (JDBC)" for details.
