Running Multiple Instances of the CMS without using Host Headers?

I installed MojoPortal in IIS 6.x and it runs fine. However if I install another copy of it on the server I get asp.net 4 conflicts and errors.

I don't use host headers and the only way I can run multiple instances is if i run each in it's own app pool. I would prefer to have them all running in the same app pool as we need to conserve RAM usage in IIS. We have several pools (asp.net 1,2, 4 etc) and we are seeing a performance hit now.

Host headers are not an option. Is it possible to run multiple copies on the same server without asp.net assembly conflicts?

Re: Running Multiple Instances of the CMS without using Host Headers?

This should not be a problem, I have multiple instances running in different app pools w2003 IIS6 here.

I assume you have unique IP address for each site.

Have you checked all the ASP.NET bindings on the sites ar all set correctly.

What are the errors?

Have you checked there is not another web.config higher up the folder tree holding the site that has the problem?

Re: Running Multiple Instances of the CMS without using Host Headers?

I can make multiple installs work in separate app pools, however I was hoping to run all of the mojoportal instances in one pool like i do with other asp.net 4.0 apps. We have 16GB of RAM on the server, however we see a performance hit when we have many active app pools.

 

Also each has it's own IP, root folder and separate site in IIS.

Re: Running Multiple Instances of the CMS without using Host Headers?

If each has its own IIS site and is running in the root of that site then the only way I know of that a web.config conflict can occur is if one or more sites is physically located in the file system below the folder of another or if there exists another web.config in the folder above the site folder. Using the same app pool is not a cause of the conflict. However all apps using the pool must use the same version of .NET.

If you cannot change the file system arrangement to elimninate the conflicts there is some information about ways to mitigate those conflicts in our Developer FAQ

Hope that helps,

Joe

Thanks Joe. I will investigate further when I install another copy of Mojo on the server (shortly) and will post any errors I get.
