Resource Assignment
Resource assignment differs for organizations, database groups, and databases.
Resource Assignment for Organizations
System administrators can assign multiple resource bundles to each organization. System administrators can
assign a particular base database template to multiple resource bundles. Organization administrators allocate
the resource bundles to database groups and enable base DB templates. When you create databases, they draw
on the resources assigned to the database group and the base database templates enabled in the organization.
This resource isolation guarantees that different organizations and different database groups have control over
their resources.
If you chose the Express installation and enabled Create defaults in the Data Director Setup wizard, a system
resource bundle and Default resource bundle are created during setup. A Default organization with a Default
database group within that organization is also created, and the Default resource bundle is assigned to the
Default organization.
Resource Assignment for Database Groups
When you create a database group, you assign a resource bundle that specifies the resources for that group.
You cannot assign more than one resource bundle to one database group. Multiple database groups can share
one resource bundle.
When you assign a resource bundle to a database group, you can specify how to allocate each resource.
n
CPU priority or reservation.
n
Memory priority or reservation.
n
Storage allocation.
n
Storage reservation percentage.
n
A network for the database group. You cannot divide the network. You can select only one network when
you create a database group even if several networks are associated with the resource bundle.
If you do not specify the CPU or memory allocation, Data Director sets the reservation to zero but sets
expandable reservations to true. If expandable reservations is set to true, the CPU or memory can expand
beyond the specified value.
Resource Assignment for Databases
A database consumes the resources assigned to its database group.
n
You can specify the number of virtual CPUs, the memory size, and CPU and memory priority for each
database that you create.
n
You cannot specify storage allocation. All databases consume the data and the backup storage allocated
to their parent database group. You can specify the size of data or PITR disk of each database.
n
Each database uses the network assigned to the database group as the DB access network.
