The Oracle Exadata Deployment Assistant is normally used when the system is initially installed and configured, and its purpose is to gather networking information for the Database Domains and for the physical components in the Oracle SuperCluster T5-8, such as the SPARC T5-8 servers, Exadata Storage Servers, switches and PDUs. However, in this section, you will be using the Oracle Exadata Deployment Assistant to gather networking information for the clusters and single-instance database zones that you want to set up.
Because you will be using the Oracle Exadata Deployment Assistant to gather networking information for clusters and single-instance database zones, rather than for physical components as the tool was originally intended for, it's useful to keep these things in mind as you perform the procedures in this section:
The Database Machine Prefix would normally refer to the name of the Oracle SuperCluster T5-8 as a whole, and would be used as a prefix for the hostnames for the components inside the Oracle SuperCluster T5-8. However, for the procedures in this section, the Database Machine Prefix refers to the name for the cluster that you will be setting up, and will be used as a prefix for the zones that are a part of that cluster.
The Oracle Database Deployment Assistant would normally assign hostnames to the compute nodes (the SPARC T5-8 servers) in several areas, such as the Administration Network. However, in some areas in this section, information that is being entered for compute nodes will actually apply to the zones that are part of this particular cluster, not to the compute nodes themselves. The instructions in this section will point out when information that needs to be entered for compute nodes actually applies to zones rather than compute nodes.
In other areas in this process, information that is being entered for a compute node actually does apply to the compute node and not to a zone in the cluster, such as the ILOM host name and IP address for the compute node. The instructions in this section will point out when information that needs to be entered for compute nodes actually does apply for the compute nodes, and not for zones in this cluster.
When the Oracle Database Deployment Assistant is first run on your Oracle SuperCluster T5-8 during the initial installation and configuration, part of the process would include assigning host names and IP addresses to the switches and PDUs. Because you are using this same tool in this situation to gather networking information to be used for the clusters and single-instance database zones, certain screens will have networking information for the switches and PDUs that will be based on the information you are entering for this particular cluster, and would therefore be different from the information that was originally entered for those components when your system was first set up. The networking information for the switches and PDUs are not cluster-dependant, so you will be asked to manually change the networking information for those components back to their original values several times in these procedures.
