Table Of Contents
DB parameter groups are associated with base DB templates and contain the database configuration settings
used to provision database instances. DB parameter groups specify database configurations that vary from db
engines. For vFabric Postgres, this includes parameters such as connection, memory, IO, WAL, checkpoint,
logging, and so on. When organization administrators enable a base DB template, they can use the default DB
parameter group for the template. They can also create a new DB parameter group or copy from another
template, so that database users can choose a parameter group based on actual need when provisioning
databases.
Resource Templates
Database Resource templates define the computing and storage resources for creating a database, the database
parameter group, and the high availability settings.
Resource Settings
When you create a template, you can specify the number of virtual CPUs,
memory size, and recommended database storage allocation. You can enable
high availability for the template and all corresponding databases. You can also
choose the CPU and memory priority, which affects the allocation of resources
for all databases in the database group. The levels (high, medium, and low)
give certain databases higher priority than other databases in the same
database group. The CPU reservation and Memory reservation text boxes let
you reserve resources for each database that you create from the template.
If you make changes to a template, databases that are already created from the
template are not affected.
You can create different templates for different situations. For example, you can define a resource template for
engineering with a small memory size and have high availability disabled. You can define the resource template
for QA with a larger memory size and with high availability enabled.
Backup Templates
Backup templates define backup settings for databases. You can associate a backup template with a database
when you create the database, or you can associate a backup template with a database at a later time. See
“Select a Database Backup Template,” on page 153.
You can use one of the predefined backup templates for consistency across your organization. See “Backup
Template Settings,” on page 152.
You can also clone and customize an existing template and associate the custom template with your database.
You can customize frequency, start time, and retention for snapshots and for external backup. You can also
enable and customize point-in-time recovery, and you can specify a backup label. See “Create a Backup
Template,” on page 95.
Enable a Base DB Template
Organization administrators enable a base DB template on the underlying resource bundles so that
organization users can provision databases based on the base DB template. Only organization administrators
and users with Manage base DB templates privileges can enable, disable, and edit base DB templates.
Prerequisites
System administrators have assigned at least one base DB template to the resource bundles of the underlying
organization.
Log in to Data Director as an organization administrator or as an administrator with privileges to enable base
DB templates.
