Upgrading

Configuring Security for the Terracotta Server Array

The Terracotta keychain file for the Terracotta Server Array (TSA) now uses the obfuscation scheme by default. If you have configured security for the TSA, and prefer to retain the original encryption scheme for the keychain file, you must explicitly configure the following secret provider in the Terracotta configuration file:


<servers security="true">
...
<server ... >
<security>
<keychain>
..
<secret-provider>com.terracotta.management.security.ConsoleFetchingBackend</secret-provider>

Simplified Configuration of tc-config

If you are upgrading from an earlier version of Terracotta configuration, note that tc-config.xml has extensive changes:

See the TSA Configuration Reference for a complete listing and definitions of configuration elements.

Configuration changes to admin.xml (when upgrading from 4.0.0 to 4.0.1)

TMS has changed admin.xml format. While upgrading to 4.0.1 from 4.0.0, a new file will be created and the old configuration information will be available in a backup file in folder : ~/mgmt/server/. Connections can also be established using TMC via the new Connection link on home page.
