To upgrade the software, you must upgrade the DEB or 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. Contact Ocient Support for assistance with the upgrade process.
The Ocient System does not support the downgrade of the software.
Consult the release notes for the target version. The version might have changes to any of the supported operating systems, the required operating system configuration, or the rolehostd configuration.

​
Ocient System Prerequisites

  • An existing Ocient installation is present on each node in the cluster.
  • The RPM or DEB file is locally available on the file system.
  • No jobs are running on the Ocient cluster.
  • All nodes have stopped the rolehostd service. For details about stopping the rolehostd service, see the Startup and Shutdown Procedure.

​
RPM Upgrade

Consult the documentation of the package manager of your operating system for specific options and command-line syntax.
Use this command to upgrade using an Ocient RPM package from the local file system. Include ./ or specify the full path to the RPM file, otherwise the dnf command attempts to search the configured repositories instead of installing the local RPM file. In this example, replace XX with the Ocient package version of the provided file.
Shell
sudo dnf install ./ocient-XX-x86_64.rpm
After the upgrade is complete, you must run the startup procedures on all nodes. For details, see Startup and Shutdown Procedure.

​
DEB Upgrade

Use this command to upgrade using an Ocient DEB package from the local file system. Include ./ or specify the full path to the DEB file, otherwise the apt command attempts to search the configured repositories instead of installing the local DEB file. In this example, replace XX with the Ocient package version of the provided file.
Shell
sudo apt install ./ocient-XX-amd64.deb
After the upgrade is complete, you must run the startup procedures on all nodes. For details, see the Startup and Shutdown Procedure. Maintenance Overview Ocient Hyperscale Data Warehouse Release Notes
