2.1.2 Eighth Rack Expansion Procedures
This section contains specific procedures that may be required for expanding some Oracle Exadata Database Machine Eighth Rack models.
Some of the following procedures only apply in specific circumstances. So, if present, check the applicability note at the beginning of the procedure. Otherwise, the expansion of an Eighth Rack through the addition of database or storage servers uses the same general procedures as the elastic expansion of a non-Eighth Rack. See Extending Elastic Configurations and Configuring the New Hardware.
Also, in the following procedures:
-
The disk group names and sizes are examples. The values should be changed in the commands to match the actual system.
-
User equivalence (password-less SSH) is assumed to exist between the
root
user on the first database server and all other database servers, and to thecelladmin
user on all storage cells. -
The text files
cell_group
anddb_group
should be created to contain lists of cell host names and database server host names, respectively.
