How to Extend the Admin Group Properties in 12c OEM

Introduction (12c OEM)

There is a default maximum for the number of values that can be supported for a target property as administration group criteria. If you see a warning message indicating that you have reached this maximum value, you can extend it using the OMS property admin_groups_width_limit. Specify the maximum number of values that should be supported for a target property. For example, to support up to 30 values for a target property that will be used in administration group criteria
