[pooja]

we are currently using 8.1 in our department.Now they asked us to work on 8.4 as well.
now my question is--

is it possible to install both 8.1 amd 8.4 on same machine? if yes how..??

If NO, what will be the best solution?

It would be great if we get detail resposne, and kindly thank you in advance.

Hi Pooja,

Yes - you can have multiple instances of Cognos 8 on the same server or group of servers.  You will need to:

a) Install Cognos 8.4 into a different location than Cognos 8.1  (eg install into a folder called c84 rather than the default c8 within Program Files).
b) Define new virtual directories in your web server for Cognos 8.4 (eg set up a virtual directory called cognos84 instead of cognos8)
c) Modify the default port numbers for the IBM Cognos 8 service, shutdown service and logging in 8.4 Cognos Configuration.
d) Use a different content store database for Cognos 8.4

Be aware that it will effectively double the memory and CPU requirements when you have both instances running, so your hardware may not be up to the job of running both instances with full user loadings.

Best regards,

MF.

b) Define new virtual directories in your web server for Cognos 8.4 (eg set up a virtual directory called cognos84 instead of cognos8)
Define additional application pools and assign each virtual directory its own pool.

Which is possible from IIS 6 and higher..
