a Client/Server online upgrade from a TimesTen version prior to 6.0” on page 113.

If you are upgrading from a version of TimesTen that is 6.0 or above, the process is much easier. Starting with 7.0, TimesTen Server is able to talk directly to all versions of TimesTen Client from 6.0 onward.

There is no need to keep the old installation of TimesTen Server when upgrading to the new version in this case. See “Performing a Client/Server online upgrade from TimesTen version 6.0 and above” on page 116.

The simple Client/Server online upgrade process minimizes, but does not eliminate, the interruption of client application access to the data store being upgraded. To maintain nearly continuous availability of a data store to all clients, you may use the approach outlined in “Online upgrades with replication” on page 94 to keep an identical copy of the data store available to the old version of TimesTen Server while you upgrade the first copy to the new version. Once the upgraded copy of the data store is available to the new version of TimesTen Server, you may stop the old version and start the new version, listening on the same port. The only interruption in availability using this method will be the very brief period during which the old server is stopped and the new server is started.

On Windows, more than one version of TimesTen cannot be installed at the same time. Therefore, it is not possible to perform online upgrades with Client/Server on Windows if you are upgrading from a version of TimesTen prior to 6.0. It is also not possible to combine the Client/ Server online upgrade procedure with that for performing an online upgrade with replication unless you use two different machines, one for each version of the data store that you are upgrading.

Performing an in-place data store upgrade

To upgrade an existing data store without exporting the data store to an external format, you can perform an in-place upgrade. This requires that all applications disconnect from the data store and that the data store be unloaded from shared memory.

Unloading a data store

TimesTen data stores remain loaded in shared memory as long as any applications or TimesTen agents (such as the cache or replication agents) are connected to them. Data stores may also be kept in shared memory, even when no applications or agents are connected, if the RAM policy of the data store has been modified using the ttAdmin
