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

DBMS Requirements

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

You must possess third-party or native JDBC 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 JDBC Data Sources.
The JDBC driver jar file (or a symbolic link to it) must be included in the active CLASSPATH.
- Supporting Java libraries (or links to them) may also need to be included in this variable value.
- Directories containing other supporting libraries may need to be included in one of the other shared library environment variables (e.g., LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH).
You must have a Java Runtime Environment (JRE) that is compatible with the Multi-Tier "Enterprise" Edition Request Broker and Bridge Agent(s) for JDBC Data Sources.
- Generally, the latest JVM from http://java.com/ is the best choice.
- If using a 64-bit JDBC Driver, you must have a 64-bit JVM, and 64-bit Multi-Tier "Enterprise" Edition Request Broker and Bridge Agent(s) for JDBC Data Sources.

The Bridge Agent(s) for JDBC Data Sources must be installed on the same machine as the JDBC drivers that connect to the target database.
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 third-party JDBC driver.
All JDBC-related environment variables should be set prior to installation. This is typically accomplished simply by logging in as the owner of the local third-party JDBC 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
```
You must know the driver class name of your JDBC driver.
You must know the full details of the JDBC connection URL that connects to your target JDBC Data Source.
