Distributing Framework Manager Components
connect to an additional, dedicated gateway that is configured to connect to the dispatcher using the internal dispatcher URI. You must configure appropriate security for this gateway, such as SSL . This method is useful when the modeling tool is outside a network firewall.
Note: Do not change your main gateway to use the internal dispatcher URI. Doing so reduces the security of the IBM Cognos 8 portal and studios.
Where you install Framework Manager, and how you configure it, can depend on how large your metadata models are and on which Web server you use.
Web Servers Other Than Microsoft IIS
For Web servers other than Microsoft Internet Information Services (IIS), no functional difference exists between the two communication routes between the modeling tool and the Application Tier Components dispatcher. For either route, the modeling tool uses the BI Bus SOAP API. If you use the Web server route, and you have medium- and large-sized packages (approaching 1 MB), the models are broken into smaller pieces (chunked) for transmission.
If you use a Web server other than Microsoft IIS, we recommend that you configure the modeling tool to communicate through your Web server gateway (using the first route). This eliminates the need to set up additional communications channels if you use firewalls to separate the modeling tool, Web server, and Application Tier Components.
Firewall Considerations
When the modeling tool is outside a network firewall that protects the Application Tier Components, communication issues with the dispatcher can occur. For security reasons, the default IBM Cognos 8 configuration prevents the dispatcher from accepting requests from the modeling tool when it is outside the network firewall.
Configuration Requirements
Framework Manager communicates with the Application Tier Components, which can be installed on one or more application servers. To publish packages, you must configure Framework Manager to communicate with the dispatcher, either directly or through a dedicated gateway.
You must ensure that Framework Manager can communicate with IBM Cognos 8 server components. On the computer where Framework Manager is installed, configure the following environment properties:
- Gateway URI
- Dispatcher URI for external applications
If the modeling tool is using a dedicated gateway instead of communicating directly with the dispatcher, you must also configure the Dispatcher URIs for gateway property on the dedicated gateway computer.
