ACS - RunSQL scripts - Add function usage feature to block Run SQL Scripts

We would like to use WRKFCNUSG entries to limit this access by specific user ID's at the partition level.
The existing controls to disable 'Run SQL Scripts' in the ACS emulator and Base product option does not work at the partition level. Ideally this could be extended to Toolbox for Java calls as well.

Reasoning: There may be instances where a particular person may install ACS without the registration entries in Windows required to block it at that level.
Additionally the block would not be desired on all partitions (example: a Developer would need ODBC access to a Development partition but not a Production partition.)

There is an existing support document: - Restrict Users from Accessing Functions in Access Client Solutions (ACS) ( that explains the process.

However, this process does not appear to work at all with ACS regardless of the settings being changed on the QIBM_XE1_ODBC entry. We have tried testing this on multiple IBMi 7.4 (TR4 & TR5) partitions with no success.

Is there a way to limit access from the partition level that does indeed work..

The only other option (drastic) we can think of is to use the process of redirection of incoming ODBC workload by user ID to an inactive subsystem. (Basically the approach of workload capping for ODBC/JDBC traffic by user ID to force the undesired traffic to be terminated).

The reply to this ticket was as follows:

My colleague on the data access team provided the following feedback:

On the ACS client the Run SQL Scripts feature can be restricted using steps 1 or 2 in the technote referenced. There is no function usage feature for Run SQL Scripts so it cannot be prevented in that way. Run SQL Scripts hasn't used ODBC for a very long time (V4R4?) it uses the Toolbox JDBC driver for connections. If the customer would like to add a function usage feature for Run SQL Scripts, he will need to submit a Request For Enhancement (RFE).

Use Case:

Prevent access to Run SQL Scripts in ACS at the partition level by user id using WRKFCNUSG or another method to allow such control.

This will prevent users from running SQL scripts via ACS where the access is not wanted while allowing the user to run this on other IBMi partitions where it is desired.

    Since there is an existing solution, no additional support is planned at this time.

    Thank you for submitting your Request For Enhancement. IBM i Access Client Solutions (ACS) supports the same WRKFCNUSG settings supported by IBM i Access for Windows (end of life was 2019). System i Navigator was the component (in Access for Windows) where Run SQL Scripts was previously supported. The following WRKFCNUSG settings are still used to control access to the Database features in ACS:
    Disabling all of those will also disable Run SQL Scripts in ACS. Schemas and SQL Performance Center will also be disabled.

    Does this meet the requirement?
