OpenText Analytics Database 26.2.x – Types of database users

Admin: Database administration user

Mon, 01 Jan 0001 00:00:00 +0000

On installation, a new OpenText™ Analytics Database automatically contains a user with superuser privileges. Unless explicitly named during installation, this user is identified as dbadmin. This user cannot be dropped and has the following irrevocable roles:

With these roles, the dbadmin user can perform all database operations. This user can also create other users with administrative privileges.

Important

Do not confuse the dbadmin user with the DBADMIN role. The DBADMIN role is a set of privileges that can be assigned to one or more users.

This documentation often refers to the dbadmin user as a "superuser". This term is unrelated to Linux superusers.

Creating additional database administrators

As the dbadmin user, you can create other users with the same privileges:

Create a user:

=> CREATE USER DataBaseAdmin2;
CREATE USER

Grant the appropriate roles to new user DataBaseAdmin2:
```
=> GRANT dbduser, dbadmin, pseudosuperuser to DataBaseAdmin2;
GRANT ROLE
```
User DataBaseAdmin2 now has the same privileges granted to the original dbadmin user.

As DataBaseAdmin2, enable your assigned roles with SET ROLE:

=> \c - DataBaseAdmin2;
You are now connected to database "VMart" as user "DataBaseAdmin2".
=> SET ROLE dbadmin, dbduser, pseudosuperuser;
SET ROLE

Confirm the roles are enabled:

=> SHOW ENABLED ROLES;
name          | setting
-------------------------------------------------
enabled roles | dbduser, dbadmin, pseudosuperuser

Admin: Object owner

Mon, 01 Jan 0001 00:00:00 +0000

An object owner is the user who creates a particular database object and can perform any operation on that object. By default, only an owner (or a superuser) can act on a database object. In order to allow other users to use an object, the owner or superuser must grant privileges to those users using one of the GRANT statements.

Note

Object owners are PUBLIC users for objects that other users own.

See Database privileges for more information.

Admin: PUBLIC user

Mon, 01 Jan 0001 00:00:00 +0000

All non-DBA (superuser) or object owners are PUBLIC users.

Note

Object owners are PUBLIC users for objects that other users own.

Newly-created users do not have access to schema PUBLIC by default. Make sure to GRANT USAGE ON SCHEMA PUBLIC to all users you create.
