Tungsten Replicator

Downgrading to an Earlier Release

If after upgrading Tungsten Replicator you are experiencing problems, and Continuent Support have suggested that you downgrade to an earlier version, follow these steps to revert your existing installation.

  1. Stop Tungsten services on all servers:

    shell> stopall
  2. Extract the release of Tungsten Replicator that should be installed instead, if not already done so

  3. If installed via the Staging Method, use tpm fetch to retrieve the current configuration. Skip to the next step if installed via the INI method.

    shell> ./tools/tpm fetch --user=tungsten --hosts=host1,host2,host3,host4 --release-directory=/opt/continuent
    Note

    In the event that the tpm fetch operation fails to detect the current configuration, run tpm reverse on one of the machines in the configured service. This will output the current configuration. If necessary, execute tpm reverse on multiple hosts to determine whether the information matches.

    If you execute the returned text from tpm reverse, it will configure the service within the local directory, and the installation can then be updated.

  4. Change into the correct release directory, and update Tungsten Replicator to deploy the new release, if running an INI deployment, you will need to execute this on all servers:

    shell> cd /opt/continuent/software/tungsten_replicator-7.1.4-81/
    shell> ./tools/tpm update --replace-release
  5. Start all the services on the Primary:

    shell> startall
  6. Start the services on remaining servers:

    shell> startall
