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.
Stop Tungsten services on all servers:
shell> stopallExtract the release of Tungsten Replicator that should be installed instead, if not already done so
If installed via the Staging Method, use
tpm fetchto 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/continuentNoteIn the event that the
tpm fetchoperation fails to detect the current configuration, runtpm reverseon one of the machines in the configured service. This will output the current configuration. If necessary, executetpm reverseon 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.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-releaseStart all the services on the Primary:
shell> startallStart the services on remaining servers:
shell> startall
