How to restrict Oracle Forms Users to access OEBS during Maintenance

Hi All,

We are in the middle of one of the important tax project go live, which needs to be done during business hours(some steps). While doing so, we dont want any end users to login and make any changes in OEBS.

The challenge is, the OEBS is online , so any user might login and make changes. We thought of sending alert, however that may not guarantee that users will not login.

Also, If we try to end date users , then we need to disable/put on hold of  all conc jobs scheduled by them which will be again tedious job, this will also affect WF items if any  orders needs to process , then it will hang in.
