Decision Insight 20200928 Save PDF Selected topic Selected topic and subtopics All content Cluster prerequisites Hardware prerequisites Make sure you have checked all the installation prerequisites. These prerequisites apply to all node types which are part of a clustered deployment: Primary/Replica or HA Main/Backup. For more information, see Clustered deployment. Hardware prerequisites All nodes must have the same hardware configuration in term of CPU, memory and disk space. See Hardware prerequisites. Software prerequisites All nodes must have the same operating system and the same Decision Insight release. In case the embedded JRE is not used (see How to change the JRE of a node?), then the same version of the JRE must be used on all nodes. Network prerequisites Two network interfaces must be available on all nodes of the cluster. The default interface is for the HTTP, JMX, ... data and is meant to be connected with other pieces of equipment that need to access to the deployment, like in the standalone deployment setup. The second interface must be dedicated to internode communications. This network must not be accessible from outside the cluster. For each node, the IP of the interface of this private network must be specified in the node configuration in order to route all the internode traffic through this network. For information purpose, the following TCP/IP port will be used in this network: 9010 (or other - configurable) for session sharing, redolog transfer, checkpoint transfer & distributed computing Related Links
