10.4.3. Upgrades with an INI File

Use the tpm update command to upgrade to the latest version.

shell> cd /opt/continuent/software
shell> tar zxf tungsten-clustering-6.1.20-5.tar.gz
shell> cd tungsten-clustering-6.1.20-5
shell> ./tools/tpm update --replace-release


The use of --replace-release is not mandatory for minor configuration changes. however it is highly recommended when upgrading between versions.

Using this option will ensure that underlying metadata and property files are cleanly rebuilt, thus ensuring any new or deprecated properties between releases are correctly added/removed acordingly.

After unpacking the new software into the staging directory, the tpm update command will read the tungsten.ini configuration and install the new software. All services will be stopped and the new services will be started.


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:

shell> ./tools/tpm update dataservice --no-connectors

The connectors must be updated separately on each server by running:

shell> tpm promote-connector

During the lifetime of the cluster, switches may happen and the current Primary may well be a different node than what is reflected in the static ini file in the master= line. Normally, this difference is ignored during an update or an upgrade.

However, if a customer has some kind of procedure (i.e. automation) which hand-edits the ini configuration file master= line at some point, and such hand-edits do not reflect the current reality at the time of the update/upgrade, an update/upgrade will fail and the cluster may be left in an indeterminate state.


The best practice is to NOT change the master= line in the INI configuration file after installation.

There is still a window of opportunity for failure. The update will continue, passing the CurrentTopologyCheck test and potentially leaving the cluster in an indeterminate state if the master= option is set to a hostname that is not the current Primary or the current host.
