MailBag Friday (#18)

Every Friday, we dedicate this space to sharing solutions for some of the most frequently asked questions posed to our ThinManager Technical Support team.  This weekly feature will help educate ThinManager users and provide them with answers to questions they may have about licenses, installation, integration, deployment, upgrades, maintenance, and daily operation.  Great technical support is an essential part of the ThinManager platform, and we are constantly striving to make your environment as productive and efficient as possible.



We use Thin Manager version 3.3.  I noticed under the Properties tab there are values for Terminal Memory Information.  What do those number represent?  I have several sessions running Wonderware Intouch and most of them have the same values leaving plenty of extra memory but a couple of session who’s numbers are much smaller.  I would like to make them the same if I can and see if the rebooting time improves.


The Total Memory is the amount of physical memory installed on the terminal motherboard that is available to the terminal. Because some of the physical memory may be used for video you don’t often see 32 MB, 48 MB or 64 MB, but see instead 29.8, 45.7, or 61.3 MB.

The Free Memory is memory that is not being used to run the firmware, render the graphics, or communicate with the terminal server.  Different terminals will have different loads depending on the number of sessions they are displaying and what that session is doing.




 I am trying to use an iFIX terminal server session and pass it between an actual thin client and the WinTMC .  It seems the way to do this is through TermSecure with the TermSecure user having the iFIX session as a Display Client, not the terminal itself.

Is there another way to do this?



TermSecure is designed to be ‘portable’ in the sense that you can assign applications/display clients to a certain user and have that application go where the user goes. Having the display client assigned to a specific terminal restricts it to that specific device.

If you wanted the application to be visible on terminal A then have it switch to fat client B, assigning the application/display client to a TermSecure user would be the way to go.




Our terminal server has a screen resolution of 1280×1024 (recommended screen resolution of any DeltaV Workstation).  Our tablet PC which we are using to connect to this terminal server has a screen resolution of (1024×768).


We would like the larger resolution image on the terminal server to be shrunk down so that it scales down and fully fits onto the smaller screen of the tablet PC to allow us to see the full contents of the larger display on the smaller tablet PC.

Any ideas? 


If they are trying to show a 1280×1024 DeltaV session on a 1024×768 then they need to set the WinTMC video to 1280×1024 on the Video Resolution page of the Terminal Configuration Wizard for that tablet and then connect to a fresh session.





If your OS crashes and you reinstall on the same exact PC with all the same hardware and software, can you reinstall your original License file if you retained it?


The install Id comes from 3 sources. They are, by order used by ThinManager, (1) serial number of the mother board, (2) the MAC address of the network card, and the (3) GUID of the OS install.  If you re-install on the same hardware the mobo serial (1) and MAC (2) will be the same so the original license will work. Only if the GUID is used (rare) or you swap out hardware will you have to re-activate.
