How to disable login / sign in from web client

Does anyone know of an easy way to disable additional logins on the web server while keeping it running and not impacting the users already logged in to it? There's lots of ways to do it with security, ocm, etc, but everything we've come up with impacts the users already logged in, or just results in more work than it's worth. A typical scenario is, we have a system problem...users are still logged in...we want to stop additional people from logging in while we work to get the existing users off the system "gracefully" without just taking it down. Any ideas would be appreciated... To put things in perspective, we have approx 1,300 users today and expect up to 2,500 total...

Backup the index.html. Then create a basic web page saying the system is not available and save it as index.html.

Our users go to:

Http://serverort/jde/owhtml

The index.html sitting inside the owhtml folder then calls the E1Menu.maf

If the users bookmarked the E1Menu.maf link this wouldn't work all the time but might prevent some of the users from getting in.

Hi,

This works in Xe :

Update the table F0093 and replace all the Jxx7333
entries (LLLL field) to Zxx7333 (JDV7333 to ZDV7333, etc).

When users login (via Web or Fat), one of the first
JDE does is to read that table to identify which
environments the user (or role) can login to.

Given that Z environments don't exist, they won't
be able to login there. Of course, a similar
strategy can also be applied to Fat or WTS environments.

Users that are already logged-in will continue working,
but new users won't find any usable J* environment.

Once your work is done, you just have to re-update
your F0093 and set the LLLL field back to Jxx7333.

As far as I tested, you don't need to restart services
or instances.

Regards,
