This process must be run from the staging directory in order to run properly. Determine where the current software was installed from.
tpm query stagingtungsten@staging-host:/opt/continuent/software/tungsten-clustering-5.3.6-24
This outputs the hostname and directory where the software was installed
from. Make your way to that host and the parent directory before
proceeding. Unpack the new software into the
and make it your current directory.
tar zxf tungsten-clustering-5.3.6-24.tar.gzshell>
Before performing and upgrade, please ensure that you have checked the Appendix B, Prerequisites, as software and system requirements may have changed between versions and releases.
Before any update, the current configuration must be known. If the
environment variables were used in the original deployment, these can be
set to the directory location where the configuration was stored.
Alternatively, the update can be performed by fetching the existing configuration from the deployed directory by using the tpm fetch command:
./tools/tpm fetch --reset --directory=/opt/continuent \ --hosts=host1,autodetect
This will load the configuration into the local staging directory. Review the current configuration before making any configuration changes or deploying the new software.
This will output the current configuration of all services defined in the staging directory. You can then make changes using tpm configure before pushing out the upgrade. Run tpm reverse again before tpm update to confirm your changes were loaded correctly.
This will update the configuration file and then push the updates to all hosts. No additional arguments are needed for the tpm update command since the configuration has already been loaded.
The tpm update command may cause a brief outage while restarting the connectors. This will occur if you are upgrading to a new version You can avoid that with:
The connectors must be updated separately on each server by running:
The tpm command will use connector graceful-stop 30 followed by connector start when upgrading versions. If that command fails then a regular connector stop is run. This behavior is also applied when using tools/tpm update --replace-release.
