The following is a real life example of how a BlueZone administrator can make BlueZone configuration modifications without
affecting your users’ personalized configuration settings.
Scenario
Let's say that your users are allowed to make and save their own display and keyboard mapping customizations to their BlueZone
Mainframe Display sessions. However, a situation comes up that requires a change to the IBM 3270 Mainframe Host IP Address
(or DNS Name).
Not using the profile schemes feature
If you are not using the profile schemes feature, you must modify your top-level BlueZone configuration profile by changing
the IP address (or DNS name). Then, you must instruct all your users to rename their current .zmd file. The next time they run BlueZone Web-to-Host, the modified .zmd file is downloaded. This accomplishes the task of changing the host IP address but all your users’ personalized customizations
like display, font, or keyboard mapping changes are lost, unless you teach your users how to export these settings from their
old renamed .zmd file and import them into the new .zmd file that was just downloaded.
Using the profile schemes feature
When using the profile schemes feature, your .zmd file already has the Profile Schemes dialog configured to allow the importation of a TN3270E dialog-level profile (.tn3). The .tn3 file contains all of the BlueZone Mainframe Display TN3270E configuration settings like Host IP Address (or DNS Name) and
TCP Port. Using the Wizard, modify your .zmd file by modifying the Host IP Address (or DNS Name). Then save just the TN3270E dialog settings as a dialog-level configuration profile. It automatically has
the same name as your .zmd file and is automatically created with a file extension of .tn3, and is written to the proper location on your workstation or web server.
Once you add the new .tn3 file to your downloaded file list, the new .tn3 file is automatically downloaded to all your users the next time they launch BlueZone Web-to-Host.
When this new .tn3 file is downloaded to your users, only the TN3270 settings in your users’ .zmd file are overridden, leaving all the users’ personalized customizations intact.
Summary
|
• |
Using the profile schemes feature, it is possible to allow your users to make BlueZone configuration customizations, yet still
allow the BlueZone administrator make configuration modifications without overwriting the users’ customizations.
|
|
• |
You must have the Allow Local Save? feature enabled in order for the profile schemes feature to work.
|
|
• |
You must pre-configure your top-level configuration profile in advance by selecting the feature or features you want to be
able to override.
|
|
• |
The Web-to-Host control module never allows the overwriting of a top-level BlueZone configuration profile (.zmd file).
|
|
• |
The profile schemes feature works by a downloading a dialog-level configuration profile which overrides values stored in the
users’ top-level configuration profile. In other words, you have a constant top-level configuration profile that never changes,
and you modify it by adding dialog-level configuration profiles that override values in the top-level configuration profile.

|
• |
A dialog-level configuration profile is a subset of a top-level configuration profile. |
|
• |
There are as many as nine (9) dialog-level configuration profiles for a single top-level configuration profile. |
