Upgrading a Cluster with the Data Hub Module
Prerequisites:
- Before upgrading, be sure to read the release notes for the new version. The release notes contain a list of known issues, important compatibility information, supported upgrade paths, and module-specific data backup recommendations.
- Apply all the latest updates available for your operating system, especially those that resolve issues with Java.
-
Important: We recommend that you create a backup before upgrading so that you can recover your flows, security settings, and other settings, if an error occurs during the upgrade process.
-
Note: If you have customized settings in the wrapper.conf file located in <SpectrumDirectory>/server/bin/wrapper, we recommend that you copy this file to a separate location before you upgrade the Spectrum™ Technology Platform server. After you complete the upgrade, compare the contents of wrapper.conf installed during the upgrade with the contents of the saved copy of the file. You can then manually copy customizations that you want to retain after the upgrade into the updated version of the file. This is particularly important for changes to the initial and maximum Java heap sizes.
In a cluster that runs the Data Hub Module, each node hosts the Spectrum™ Technology Platform server as well as Data Hub Module models. When upgrading, you need to upgrade your models in addition to upgrading the Spectrum™ Technology Platform server.
The upgrade process consists of these steps:
- Back up your models and properties files.
- On the master server, upgrade Spectrum™ Technology Platform then upgrade your models.
- On each non-master server, upgrade Spectrum™ Technology Platform then copy the upgraded models from the master server to the non-master server.
To upgrade a cluster that runs the Data Hub Module, follow this procedure:
