Privileges for geodatabases in Db2

Privileges determine what someone is authorized to do with the data and the database. Privileges should be assigned based on the type of work the person does within the organization. Is this person involved with administration of the geodatabase? Does he or she need to edit or create data? Or would this person only need to query the data?

Privileges are set at different levels. The tables in this topic list the minimum required database and dataset privileges for common types of geodatabase users: data viewers, data editors, data creators, and the geodatabase administrator.

Privileges for users in geodatabases on Db2 on Linux, UNIX, and Windows are different than those required for geodatabases on Db2 on the IBM z operating system (z/OS). Therefore, there are two different tables of user privileges.

You can use Db2 tools or SQL statements to administer database privileges.

Privileges on datasets in geodatabases should be granted or revoked using ArcGIS clients and must be done by the dataset owner.

Db2 on Linux, UNIX, and Windows

Db2 grants CREATETAB, BINDADD, CONNECT, and IMPLICITSCHEMA database authority plus USE privilege on the USERSPACE1 table space and SELECT privilege on the system catalog views to the PUBLIC group by default. To remove any of these database authorities, a database administrator must explicitly revoke them from PUBLIC.

If any of these privileges are removed from PUBLIC, they need to be granted to individual database users or groups. For example, if CONNECT is revoked from PUBLIC, it needs to be granted to anyone who needs to connect to the database. Similarly, if SELECT on the system catalog views or tables is revoked from PUBLIC, individual users or groups must be granted SELECT on the following or they will not be able to connect to the geodatabase:

  • SYSIBM.SYSDUMMY1 (catalog view)
  • SYSCAT.ROLEAUTH
  • SYSCAT.DBAUTH
  • SYSCAT.TABAUTH

Type of userDatabase privilegesDataset privilegesNotes

Data viewer

  • CONNECT to database
  • EXECUTE on MON_GET_CONNECTION

SELECT on database objects, SELECT on SYSIBM.SYSDUMMY1, SYSCAT.ROLEAUTH, SYSCAT.DBAUTH, and SYSCAT.TABAUTH

If your database is configured to use shared log file tables (the default), the following additional privleges are needed:

  • CREATETAB
  • IMPLICIT_SCHEMA

The MON_GET_CONNECTION function cleans up defunct processes from the PROCESS_INFORMATION table when the user connects. To clean up connections, the user must be able to execute MON_GET_CONNECTION.

Data editor

  • CONNECT to database
  • CREATEIN, ALTERIN, and DROPIN for the necessary schema
  • EXECUTE on MON_GET_CONNECTION

  • SELECT, INSERT, ALTER, and DELETE privileges on other user's tables.
  • CONTROL, ALTER, DELETE, INSERT, SELECT, UPDATE REFERENCES, SELECT on SYSIBM.SYSDUMMY1
  • SELECT on SYSCAT.ROLEAUTH, SYSCAT.DBAUTH, and SYSCAT.TABAUTH

Table and feature class owners use the Privileges dialog box or Change Privileges geoprocessing tool in ArcGIS to grant editing privileges on their data to other users.

The MON_GET_CONNECTION function cleans up defunct processes from the PROCESS_INFORMATION table when the user connects. To clean up connections, the user must be able to execute MON_GET_CONNECTION.

Data creator

  • CONNECT to database
  • CREATETAB in database
  • CREATEIN, ALTERIN, and DROPIN for the necessary schema
  • EXECUTE on MON_GET_CONNECTION

CONTROL on database objects, SELECT on SYSIBM.SYSDUMMY1

SELECT on SYSCAT.ROLEAUTH, SYSCAT.DBAUTH, and SYSCAT.TABAUTH

The MON_GET_CONNECTION function cleans up defunct processes from the PROCESS_INFORMATION table when the user connects. To clean up connections, the user must be able to execute MON_GET_CONNECTION.

Geodatabase administrator (the sde user)

  • DBADM authority
  • SYSCTRL or SYSADM authority
  • EXECUTE on MON_GET_CONNECTION

The DBADM authority gives the sde user all privileges against all objects in the database and allows him or her to grant these privileges to others. It is required to create or upgrade a geodatabase.

DBADM authority is also necessary to remove client connections from the database. In addition, the sde user must have either SYSCTRL or SYSADM authority to remove client connections from the database.

The MON_GET_CONNECTION function cleans up defunct processes from the PROCESS_INFORMATION table when the user connects. To clean up connections, the sde user must be able to execute MON_GET_CONNECTION.

Db2 for z/OS

Security on z/OS is higher than on other platforms. Most privileges are not automatically granted to PUBLIC by default; you need to grant privileges to individual user IDs or groups.
