If you plan to enable point-in-time recovery, calculate additional storage to accommodate the point-in-
time recovery write-ahead logs (WALs). The size of the allocation depends on the expected volume of
transactions on the database.
Every database requires a certain amount of storage overhead for the operating system, database software,
swap space, log files, snapshots, and so on. The storage for overhead is explicitly allocated and does not count
against database storage allocation. Database storage allocation is for the database schema and data only. You
must have enough resources available to cover the database allocation and to cover any overhead.
Even if the database group has enough free space for creating a database, database creation does not finish if
you do not have enough resources for the overhead. If the free space is less than the following calculation, Data
Director cannot create the database.
(storage allocation * storage reservation %) + overhead
Database Creator Permissions
After database creation finishes, the following permissions on the new database are granted to the database
creator.
Edit information and
storage
Enables the database creator to edit database properties such as the name,
description, and size of the database.
Manage IP whitelists
Enables the database creator to assign IP whitelists to this database and to create
custom IP whitelists for this database.
Modify administrator
accounts
Enables the database creator to add or modify database users for this database.
Database users are granted full permission on this database.
Start database and Stop
database
Enables the database creator to start and stop.
View properties
Enables the database creator to view the database.
Edit settings
Enables database creators to edit database parameters, database ingestion, and
refresh settings and SSL certificates.
Monitor status
Enables database creators to monitor dashboards, events, tasks, reports, and
logs. You can also define, monitor, and acknowledge alarms.
Database Creation
As a DBA or application developer, you create databases to serve your project or application requirements.
Data Director provides several methods for creating and provisioning databases.
n
“Create an Empty vFabric Postgres, MySQL, or Oracle Database,” on page 103. Use a resource template
to create an empty database. Use this method when developing a new application or the database
characteristics or data are not important to the current phase of your project.
n
“Create a Database from a Catalog,” on page 107. Use this method when you require a database with
known characteristics and pre-loaded data. Catalog databases are read-only and cannot be modified or
powered on by users, though the data in the catalog database can be refreshed periodically from the source
database.
n
Create a database by cloning an existing database. Use this method to create a database in a pristine state,
with pre-loaded data and configuration settings, for testing and development purposes. See Chapter 10,
“Cloning Databases,” on page 127.
