Ocient Software Upgrade
To upgrade the software, you must upgrade the RPM package on each node in the cluster. Versions of the Ocient software must match across the cluster, so upgrades must be done in an all-or-nothing fashion.
The Ocient System does not support downgrade of the software.
Consult the release notes for the version to which you are upgrading. The version might have changes to any of the supported operating systems, the required operating system configuration, or the Ocient node provisioning that would require a full re-install of the node to upgrade.
- An existing Ocient installation is present on each node in the cluster.
- A DNF/YUM repository with the new Ocient RPM is available, or the RPM is locally available on the file system.
- No jobs are running on the Ocient cluster.
- All nodes have stopped the rolehostd service.
The command you use to upgrade the Ocient System depends on the version and where the RPM package file is located. Use these commands to perform the upgrade.
If you upgrade the RPM from a repository, use this code.
Consult the documentation for the package manager of your operating system for specific options and command-line syntax.
To upgrade to the latest version, use this code.
To upgrade to a specific version, use this code. In this example, ensure that you replace the XX with the Ocient package version of your choice.
If you install the RPM from the local file system, use this code. In this example, ensure that you replace the XX in the RPM filename with the Ocient package version of your choice.
Then, you must run the startup and shutdown procedures on all nodes. For details, see Startup and Shutdown Procedure.
