Chapter 2 Connectivity

This chapter provides instructions and information for setting up and testing connectivity to the following database systems:

DB2®
Notes®
ODBC
Oracle
OLE DB
Sybase

Client libraries of the external systems to be accessed must be installed on the IBM® Lotus Enterprise Integrator® (LEI) server and the Domino® server. When running activities, if the LEI server that you want the activity to run on and the Domino server where the LEI Administrator resides are on separate machines, the client libraries must be installed on both machines.

Note: Access to other IBM i DB2 Universal Database™ for IBM i (DB2 UDB for IBM i) servers is integrated into IBM i. No additional software installation is required when using the Lotus® Connector for DB2 on IBM i.

DB2 Connectivity
This section lists supported platforms and configurations. It also lists specific IBM Lotus Enterprise Integrator (LEI) activities supported by the Lotus Connector for DB2.
Connectivity to DB2
This section provides information about software required to connect to DB2. This information is provided to help you get started. You should refer to the documentation for the specific software you are using for complete instructions.
Connectivity to DB2 on IBM i
This section describes connectivity considerations between DB2 on a Microsoft Windows workstation and DB2 Universal Database for IBM i (DB2 UDB for IBM i). None of the options described require the installation of software to the IBM i.
ODBC DB2 UDB for IBM i Connectivity
ODBC DB2 UDB for IBM i connectivity is facilitated through the DB2 client. This gives the server the advantage of straight connectivity, speed, and data type access without the ODBC layer. However, if you install products such as IBM's client access for IBM i, then the connectivity is through the ODBC link. Verify the requirements of the individual packages.
Connection for DB2 CAE and DDCS
IBM Lotus Enterprise Integrator (LEI) offers native connectivity to DB2. This provides a direct connection to DB2 on all DB2-supported platforms, and enhances the DB2 connectivity previously provided through ODBC. The native interface offers improvements in speed and support for native data types not accessible through ODBC. This section contains information on configuring native DB2 connectivity through Distributed Database Connection Services (DDCS).
Sample Steps for DB2 Administration Client Configuration on Windows
The following illustrates some sample steps you may wish to follow when configuring your DB2 connectivity using the Administration client on Microsoft Windows. For full details, refer to the DB2 manual Install/Use DB2 Clients for xxx where xxx is your operating system. The following steps assume you are installing the administration client for the server machine running on Windows and using TCP/IP.
Sample Steps for DB2 Administration Client Configuration on UNIX
The following illustrates some sample steps you may wish to follow when configuring your DB2 connectivity using the Administration client on UNIX. For full details, refer to the DB2 manual Install/Use DB2 Clients for xxx where xxx is your UNIX operating system. The following steps assume you are installing the Administration client for the server machine running on UNIX and using TCP/IP.
When to Use IBM Distributed Database Connection Services (DDCS)
DDCS has been replaced by DB2 Connect™ Personal Edition and DB2 Connect Enterprise Edition.
