Enterprise Option for OpenVMS

Before installing the enterprise option for OpenVMS, review the following considerations.

A computer running the supported Alpha and VAX operating systems can use either TCP or User Data Protocol (UDP) with any of the following communications software:
- Compaq UCX 4.2 eco 3 (on Alpha)
- Compaq UCX 3.3 eco 13 (on VAX)
- Compaq TCP/IP Versions 5.0 through 5.3
- Process Software Multinet Version 4.1B (with patches) through Version 4.4
- Process Software TCPWARE Versions 5.3 and 5.4
Important! If necessary, you can install two or more of these communications packages on the same computer; however, you can run only one package at a time. Do not run two or more of these communications packages simultaneously on the same computer.

Note: If you change OpenVMS TCP/IP stacks at any time, you must reinstall the OpenVMS Enterprise Option.
You should back up your OpenVMS system disk before installing the OpenVMS Enterprise Option.
Ensure that you have at least 10 blocks of free space for setup file.
