Cognos 8.4.1 and 8.4 on the same Machine.

[NaviGator]

Hello guys,

I have Cognos 8.4.1 installed on my laptop. It's working fine and no problem. Now due to some work requirements, I need to install Cognos 8.4 or 8.3 on my laptop.

I have tried to install 8.4 with the existing installation 8.4.1 but it is not working. The service is not starting. I have tried to change the ports for everything in the new installation, changed the services names, the virtual directory names in IIS but still no luck.

Is there anything wrong or missing ? I don't want to uninstall 8.4.1 because I already have work on it. So any advice that can help me ?

Thanks a lot ..

Hm. I know that this is working perfectly for us, so you need to search for some config-mistake or so.

Hint: You don't need to change the service name. The Service name ALWAYS automatically includes the configurated port number, if this is NOT the default Port Number.

Checklist:
- All ports in the cognos configuration different between 8.4 and 8.4.1
- IIS configured for two different pages
- All URIs/URLs in the cognos configuration different between 8.4 IIS-Directory and 8.4.1 IIS-Directory
- different content stores are used (cognos configuration).

Additional: Create a separate IIS Application pool for each installation...

I have done it. It seems that the problem was in the Configurations but it is solved now. Both 8.4.2 and 8.4 are working fine in the same machine ..

the issue now is, I have created 2 separates IIS virtual directories for both installation (cognos8 and c84) . and I can access them now with no problem using URL like

http://localhost/cognos8  and
http://localhost/c84

My question is : they are working as mentioned but I didn't change anything Gateway URI property in Gateway settings in the Cognos Configurations. both Gateway URI are

http://localhost:80/cognos8/cgi-bin/cognos.cgi

I thought that we would need to change something in this URI at least for the second installation to be something like

http://localhost:80/c84/cgi-bin/cognos.cgi

but it is working now without a change. So do you know why it is working like this ??

Thanks ..

I think it's because there's not much difference between them 8.4 and 8.4.1 .... but if you didn't change anything then the c84 gateway is using the cognos8 gateway and it's using the cognos8 cognos.cgi component....

Thank you ReportNet Addict for your note.

That's mean in the normal case, I should change the Gateway for the second installation ? In my case I should have

http://localhost:80/c84/cgi-bin/cognos.cgi

as my Gateway for my second installation ?
