Be sure to check property settings after an upgrade, as described in the upgrade procedures. These include:
- Container property settings in the SpectrumDirectory\server\conf\spectrum-container.properties file
- Open search property settings in the SpectrumDirectory\index\opensearch.template file
After you complete an upgrade, you can copy customized settings from files in the backed up copy of the entire SpectrumDirectory directory that was created before the upgrade.
Configure new cluster instances property setting
This release adds the required spectrum.repository.cluster.instances property that specifies the number of database nodes in the cluster.
spectrum.repository.cluster.instances setting to the correct number of nodes, your server will fail to start and will remain in a standard server (non-cluster) state.Before you start the cluster, make sure that the spectrum.repository.cluster.instances property specifies the number of nodes in the cluster. For a separated configuration, specify the number of nodes in the database only cluster. This property is specified in the spectrum-container.properties file:
- Standard cluster
SpectrumDirectory\server\conf\spectrum-container.properties- Database only cluster
- DatabaseDirectory\repository\spectrum-container.properties
If you do not set this property setting to the correct number of nodes, your server will fail to start and be in a standard server (non-cluster) state. If this occurs, first stop the cluster and make sure all Java processes are stopped. Then, on each node, set the property to the correct number of nodes in the cluster. Finally, delete all files and folders in the SpectrumDirectory\repository\data directory except for the dbms folder. It is important that you do not delete the dbms folder, or the cluster will not start.
