Allow separate grantable authoriy for REFRESH MQT

The current authorization to issue a REFRESH TABLE on an MQT is the following (this is true up through and including v12):
The privilege set for REFRESH TABLE must include at least one of the following authorities:
•Ownership of the materialized query table
•DBADM or DBCTRL authority on the database that contains the materialized query table
•SYSADM or SYSCTRL authority
•DATAACCESS authority

If you want to delegate this authorization to application teams, the above entitlements are too great.

Providing a grantable REFRESH TABLE authority would allow for the delegation of this authority without involving a DBA who would typically have this authority, and allow application teams to maintain their own refresh of an MQT.

  • Not Under Consideration
Who would benefit from this IDEA? All persons using MQTs could allow for a granular implementation conforming with the idea of least privilege.
How should it work?



Idea Priority High
Priority Justification The introduction of the authority will allow adherence to the concept of least privilege.

    Thank you for submitting this Db2 for z/OS enhancement request.

    We have reviewed this request and believe it is a good candidate for the Db2 for z/OS product. However, it is not in our current roadmap and we are unable to deliver it within the next 36 months. Therefore, unfortunately, we will not be implementing this Idea.

    We appreciate your input to the Db2 for z/OS development team. We also hope that you will continue to submit ideas for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.
