Linux clustered server: Grant privileges to IBM DB2 for i database users
Configuration and runtime database users are granted a different set of privileges, depending on whether these users are schema owners or not. We can create a copy of the SQL scripts and edit this copy to manually grant permissions to configuration and runtime database users.
- Prerequisites
- Linux clustered server: Modify IBM DB2 for i database properties
- Linux clustered server: Create groups and assign users for IBM DB2 for i
- Linux clustered server: Create IBM DB2 for i user profiles
- Linux clustered server: Set up IBM DB2 for i databaes automatically
Required privileges of the configuration database user
When a configuration database user is a schema owner, the property...
domain.DbUser
...is assigned the same value as the property...
domain.DbSchema
...and a role is created for a configuration user in each database domain.
This role is created and assigned automatically when you run the following configuration task:
- create-database
To learn more about the specific permissions granted to the configuration database user, navigate to the SQL script templates in the installation directory of IBM WebSphere Portal. These read-only templates should not be modified. To grant these privileges, we can create a copy of the SQL scripts and use this copy to grant permissions manually.

Required privileges for the runtime database user
When the runtime database user is a schema owner, the property...
domain.DbUser
...is assigned the same value as the properties domain.DbRuntimeUser and domain.DbSchema. The runtime database user typically does not create tables used to query and manipulate data and does not by default have access to these tables. To grant minimum privileges to a runtime database user to work with these tables, access needs to be provided for the objects individually. A role is created for runtime database users in each database domain. These roles are created and assigned automatically when you run the following configuration tasks:
- create-database
- grant-runtime-db-user-privileges
Before you run these configuration tasks, the runtime database user can only access the database to validate configurations. To learn more about the specific permissions granted to the runtime database user, navigate to the SQL script templates in the installation directory of WebSphere Portal. These read-only templates should not be modified. To grant these privileges, we can create a copy of the SQL scripts and use this copy to grant permissions manually.
