Restriction rules summary:
1. If the VHSGCONF is empty, any user can browse and reply to any prompt in all
environments.
2. If one of the VHSGCONF entries is for a specific user (for example,
PROD.BATCH). then only this entry will be used when the corresponding user logs
on.
3. If a user does not have a specific entry, the corresponding group entry (for
example, PROD.*) is used for the user.
4. If the VHSGCONF file is not empty and there is no entry for the user, the user is
not able to browse and reply to the VHS prompts.

Many Windows NT workstations can see the same set of VHS prompts. So if one user
replies to a prompt, all the other workstations that have access to the same prompt are
updated. In that case, the VHS GUI will just remove the prompt on the view, based on
the EMS event generated by VHS.
Single Node Recommended Setup
If you plan to use VHS on a single node and you have a high volume of application
messages, we recommend that you use an alternate collector instead of the default
($0). By using an alternate collector, you are spreading the load across multiple CPUs
and disks, improving the VHS GUI performance.
Multiple Node Recommended Setup
If you plan to use the VHS GUI to browse application messages and prompts
distributed on multiple nodes, you need to configure and use EMS Forwarding
Distributors. These distributors require a special filter to pass only a subset of the VHS
events to a central node.
The following is an example of a filter that passes only the events required by the VHS
GUI.
Note. The user of the VHS GUI is set via the logon of the CSG.
