Pre-Installation Requirements for the Enterprise Edition (Multi-Tier) Request Broker and Database Agent(s) for DB2, for Windows

DBMS Requirements

You need to know a variety of information pertaining to your target DB2 DBMS instance and database:

You will need an installation of the DB2 native client on a supported operating system, if you cannot install the Enterprise Edition server components on the same machine as DB2. At the time of writing, this product is called DB2 Connect. Product names may vary over time.
You must know whether the local DB2 components are 32-bit or 64-bit. The Enterprise Edition server components must match the bit format of the local DB2 components, not the OS.

The Request Broker and database-specific Agents must be installed on the same machine as DB2 or a DB2 native client. If you install on the same machine as the DB2 native client, you must have a DB2 database alias configured.
You must know whether TCP ports 5000 and 8000 are already in use on the Broker host. These ports are the defaults used by our Request Broker and Web-based Admin Assistant. If other services are using these, you will need to assign different (unused) ports to the new services during installation.
For best results, the Enterprise Edition server components should be installed while logged in as the local DB2 or DB2 native client owner.
All DB2-related environment variables should be set prior to installation. This is typically accomplished simply by logging in as the local DB2 or DB2 native client owner.
