After you complete the hardware installation and cabling procedures, and power on the compute nodes in your MiniCluster, you then must go through the software configuration process. As part of that process, you need to decide on the following:
How you want your MiniCluster set up (all database virtual machine groups, all application virtual machine groups, or a mixture of the two)
How many total virtual machine groups you want
When you first get the MiniCluster, the Oracle Solaris OS is preinstalled on both compute nodes. Once you boot up both compute nodes, you then must go through the MiniCluster-specific initial installation procedures.
The mcinstall user is set up at Oracle before the MiniCluster is shipped to your site. The mcinstall user is given the main system administrator role for MiniCluster, similar to the traditional root user role. Only the mcinstall user can go through the initial installation and administration procedures.
