Pre-Installation Requirements for the Multi-Tier "Enterprise" Edition Request Broker and Bridge Agent(s) for ODBC Data Sources (a/k/a, the ODBC/JDBC/ADO.NET-to-ODBC Bridge), for Unix-like OS

DBMS Requirements

Your target data source must be SQL compliant.
You must have all information necessary to configure an ODBC connection to the data source.

You must possess third-party or native ODBC drivers that connect to your target data source. A client portion of these drivers must be installed on the same machine as the Multi-Tier "Enterprise" Edition Request Broker and Bridge Agent(s) for ODBC Data Sources.
- The ODBC driver library file (or a symbolic link to it) must be included in the active shared library environment variable (e.g., LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH).
- Supporting libraries (or links to them) may also need to be included in this variable value.
You must know whether the local ODBC components are 32-bit or 64-bit. The Multi-Tier server components must match the bit format of the local ODBC components, not the OS.

The Bridge Agent(s) for ODBC Data Sources must be installed on the same machine as the ODBC driver that connects to the target data source.
A System DSN based on the local ODBC driver should be pre-configured and tested to successfully connect to the target data source.
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 Multi-Tier server components should be installed while logged in as the owner of the local ODBC driver.
All ODBC-related environment variables should be set prior to installation. This is typically accomplished simply by logging in as the owner of the local ODBC driver, but if logged in as a different user, you can often achieve the same by using that user's .profile or similar, with a command like one of these (depending on your active shell) --
```
source ./.profile
. ./.profile
```
