Hi Guys
Slightly technical question - but does anyone have any experience of using TM1 Excel Perspectives via an Internet Proxy ?.
Are there any pitfalls ?.
Cheers
Nick

It would be helpful to explain just exactly what it is you are trying to accomplish rather than posting a generic term like "internet proxy". Based on your knowledge and/or experiences, that term can mean many things. What are you trying to do, access a TM1 server that's behind a firewall via the internet? Run a TM1 server on a cloud platform and access that server via the internet?....., etc.?

So sorry for not being specific - I was just trying to get a gauge whether this was a total no-no.
I am trying to understand how the TM1 Perspectives add-in communicates with a TM1 server.
What I want to do is access TM1 server that is internet hosted, the TM1 Perspectives client will be on a customers network which allows internet access via proxy.
Googling suggests that historically in your applix world you needed to have a TM1 HTTP proxy in place which has since been deprecated.

I haven't tested that particular setup but I have several others and the bottom line is that a direct connection of Perspectives to a TM1 server outside your local network is going to perform very poorly. This is common knowledge among TM1'ers and admitted to by IBM. If you must have Perspectives as the client, the only viable solution is to use Citrix (or Citrix-like solution), where Excel and Perspectives are loaded onto a Citrix box and the TM1 server is either running on the same box or one sitting right next to it on the network strand. So, you need to explore running Citrix over a proxy, not TM1.

My belief is that IBM have something 'in the labs' which is intended to address this.

You must be a glass half full kind of person. I am not nearly so optimistic. It's been this way for years and years. Given that all the development efforts are being put into Contributor, Insight, PM, etc., I just don't see anything happening on this front.

I was thinking about this thread just this morning when I saw  from our large blue friends:
Problem(Abstract)
It is not recommended that TM1 Performance Modeler is used over a Wide Area Network (WAN) or any network connection with significant latency between the client machine and the TM1 Server.

Although Cognos TM1 Performance Modeler can be provisioned to client machines from the TM1 Applications portal (in a web browser), this is primarily intended as a means of simplifying deployment for modelers working on a LAN.

Symptom
Use of TM1 Performance Modeler over a Wide Area Network (WAN) may result in poor responsiveness.

Knowing as you all do:

  • My fondness for Performance Muddler and
  • My appreciation of TM1's WAN performance,
visualising the volume of laughter-propelled Corn Flakes sprayed over my monitor when I read that is left as an exercise for the reader.
