Timesten - Connection

Timesten Component


An application can connect to the IMDB Cache or TimesTen database by:


You may see up to 2047 connections.

While the best response time is achieved with TimesTen running in-process with the application (also known as “direct mode”), conventional client/server access is commonly used when a database is shared by several applications running on different servers.

Applications access TimesTen databases using standard SQL via:

  • JDBC,
  • ODBC,
  • ODP.NET,
  • OCI (Oracle Call Interface),
  • Pro*C/C++,
  • and Oracle PL/SQL programming interfaces.

The routines that implement the TimesTen functionality are embodied in a set of shared libraries that developers link with their applications and execute as a part of the application's process.
