Connection Server is a CORBA server and is accessed remotely. Connection Server serves the
CORBA and HTTP clients to address the 2-tier and web tier deployment modes respectively.
See the SAP BusinessObjects Business Intelligence platform Administrator Guide for more information

3.5 Connectivity services
Three Connection Server server instances come with the default BI platform installation. They are
grouped under Connectivity Services in the Central Management Console (CMC).
Connection Server servers host the following services:
• Native Connectivity Service (64-bit)
• Native Connectivity Service (32-bit on MS Windows only)
The Adaptive Processing Server hosts the Adaptive Connectivity Service, which allows user applications
to access Java-based data sources remotely.
When starting up, the Connectivity Services advertise the list of the data sources they support on the
BI platform cluster, so that SAP BusinessObjects applications are able to look up and use the appropriate
server instance. Applications look for data sources through Connection Server frst in library mode, then
in the server mode.
Connection vs. Service
When Connection Server is used in library mode, the list of available data sources is defined by the
data access drivers and middleware installed on the local machine. When Connection Server is used
in server mode, the list of data sources also includes those supported by each server instance that runs
on the back-end system of the BI platform.
Each server instance supports a subset of the data sources supported by the Data Access layer. The
subset depends on the following parameters:
• the CS server implementation technology (C++ or Java)
• the host operating system (UNIX flavors or MS Windows)
• the drivers you can select when installing the BI platform
• the active data sources you can select for each server instance in the CMC
The following table describes which Connectivity Service each kind of connection can use.
