Pre-Installation Requirements for the Multi-Tier "Enterprise" Edition Request Broker and Database Agent(s) for Oracle, for Unix-like OS

DBMS Requirements

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

Oracle SID
Oracle TCP Port
Oracle SQL*Net or Net Service Name Only required when the Multi-Tier server components are not installed on the Oracle server.
Hostname or IP adddress of Oracle database server

You will need an installation of the Oracle native client on a supported operating system, if you cannot install the Multi-Tier server components on the same machine as Oracle itself. At the time of writing, this product may be called SQL*Net, Net 8, Net 9, Net 10, the Oracle Instant Client, or the OCI Client, depending on the Oracle version. Product names vary over time.
You must know whether the local Oracle components are 32-bit or 64-bit. The Multi-Tier server components must match the bit format of the local Oracle components, not the OS.

The Request Broker and database-specific Agents must be installed on the same machine as Oracle or an Oracle native client. If you install on the same machine as Oracle SQL*Net or Net 8/9/10/11, you need an Oracle Net Service Name 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 Multi-Tier server components should be installed while logged in as the local Oracle or Oracle native client owner.
All Oracle-related environment variables should be set prior to installation. This is typically accomplished simply by logging in as the local Oracle or Oracle native client owner, 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
```
