Esri Maps for IBM Cognos is web-based software that integrates maps and data into IBM Cognos Business Intelligence (BI) reports. Architecturally, Esri Maps for IBM Cognos offers the following benefits:
The end result is that Esri Maps for IBM Cognos integrates directly with the IBM Cognos BI architecture. It leverages in-place security, deployment capabilities, scalability, and content promotion.
Esri Maps for IBM Cognos contains a gateway component (EM4C Gateway), a dispatcher component (EM4C Dispatcher), and has its own content server (EM4C Server).
EM4C Gateway exists in the web tier and is installed on all IBM Cognos Gateway servers. In an IBM Cognos deployment, there will be one EM4C Gateway for each IBM Cognos Gateway.
The EM4C Gateway component is used to serve up static files such as images, cascading style sheets (CSS), and JavaScript resources. In addition to serving static files, this component also appends items to the IBM Cognos Report Studio toolbox.
The EM4C Dispatcher component acts as a plug-in to the IBM Cognos Report Service. This is used to bridge the communication between the BI Bus and other EM4C components.
At runtime, the EM4C Dispatcher sends prompt values and context information to the EM4C Server. This ensures both proper security and proper use of any selected user prompts.
EM4C Server is also responsible for handling the synchronization of IBM Cognos report elements at runtime by sending requests to the Cognos Dispatchers and processing the results. It is also responsible for the administration and configuration of Esri Maps for IBM Cognos content. This is done through the Esri Maps Designer interface, which is accessed from IBM Cognos Connection.
EM4C Server can be installed on any server as long as it meets the minimum requirements for a computer in an IBM Cognos deployment. No IBM Cognos components need to be installed. EM4C Server is often installed on one or more computers in the application tier of an IBM Cognos deployment for failover.
If your deployment includes more than one EM4C Server, one is configured as the proxy (or primary) server and is responsible for load balancing between other EM4C Servers. This proxy maintains an affinity cache that directs subsequent requests to the appropriate EM4C Server.
The following illustrates an example Esri Maps for IBM Cognos deployment:
