Enable Management of Change (MoC) permissive mode

  • Last UpdatedApr 24, 2025
  • 1 minute read

When Management of Change (MoC) permissive mode is disabled, MoC restricts permissive mode aware processes (listed below) from modifying configuration fields when you have not supplied a changeset. When MoC permissive mode is enabled, permissive mode aware processes can modify configuration fields when you have not supplied a changeset. These untracked configuration changes will be logged in a process-specific log and stored by the MOCOrchestrator service in the AuditLogEntries table of the ManagementOfChange Database.

Note: By default, MoC permissive mode is disabled.

The following is a current list of permissive mode aware processes:

  • Advanced Database Editor (ADE)

  • Application Calculation Engine (ACE) Editor

  • Batch Tracking Compiler (BTC)

  • LMSDel

  • DBPut

  • DBDel

If permissive mode is disabled when you run permissive mode aware processes (that is, BTC, LMSDel, DBPut, and DBDel) from Windows PowerShell without supplying a changeset, you will receive an error message indicating the change is not permitted in the current mode. When you are using ADE and ACE code editors and do not supply a changeset (that is, Read-Only Mode), the toolbar Save buttons and menu items will be disabled.

To enable MoC permissive mode

Note: For information on overriding default configuration settings, refer to Modify configuration settings.

  1. Create or open the ManagementOfChange.json file found in the following locations:

    • %DNADataRoot%\RealTime\config\Settings\ManagementOfChange.json

    • %DNADataRoot%\ManagementOfChange\config\Settings\ManagementOfChange.json

  2. Set the ManagementOfChangePermissiveMode value to true.

    The following example shows the default content of the configuration settings JSON file:

    {

    "ManagementOfChange": {

    "ManagementOfChangePermissiveMode": false,

    }

    }
