This document, "DEC TCP/IP Services for OpenVMS: Installation and Configuration" (November 1994, Part Number: AA-LU49G-TE), is a manual for OpenVMS system or network managers. It describes the step-by-step process for installing and configuring the DEC TCP/IP Services for OpenVMS software, also known as UCX (Universal Communications Executive), on OpenVMS VAX (Versions 5.5, 6.0, 6.1) and AXP (Versions 1.5, 6.1) systems.

The process is divided into four main phases:

1. Preparation: This involves backing up the system disk, ensuring necessary privileges, and verifying that the system meets hardware and software requirements (e.g., sufficient disk space, quotas, memory for BIND Server, global pagelets, and global sections). It also details configuring OpenVMS SYSGEN parameters (like Global Pagelets/Sections, Nonpaged Dynamic Pool, and Interrupt Stack Pages for VAX with PWIP) and running AUTOGEN. Crucially, a Product Authorization Key (PAK) must be registered via the License Management Facility (LMF) unless the software is solely used for displaying DECwindows applications remotely. Checklists are provided for gathering required information.

2. Installation: This phase uses the standard OpenVMS VMSINSTAL procedure to copy UCX distribution files, create directories, and provide Release Notes. Instructions are given for first-time installations and re-installations (including shutting down existing UCX, handling file purging in clusters, and managing renamed files). Troubleshooting for unsuccessful installations is also included, often pointing back to unfulfilled prerequisites or inadequate quotas.

3. Configuration: After installation, the system manager runs the UCX$CONFIG.COM command procedure. This can be done interactively via menus or using direct commands. The configuration covers the core environment (BIND Resolver, Domain, Routing, Interfaces, Time Zone), various client components (FTP, LPR/LPD, NFS Client, REXEC/RSH, RLOGIN, SMTP, TELNET), server components (BIND, BOOTP, TFTP, FTP, LPR/LPD, NFS, PC-NFS, PORTMAPPER, TELNET, SNMP), and optional components (PWIP, SRI QIO, Anonymous FTP). It also covers assigning a User Identification Code (UIC) for service accounts. An Installation Verification Procedure (IVP) is run to test the configured software, and error handling for common IVP issues (e.g., incorrect network configuration, missing PAK) is provided.

4. Post-Configuration: This phase includes essential tasks to make UCX fully operational:

   • Editing system startup (SYSTARTUP_VMS.COM) and shutdown (SYSHUTDOWN.COM) procedures to automatically start and stop UCX.
   • Verifying SYSLOGIN.COM file protections.
   • Populating relevant databases (e.g., /etc/hosts, /etc/networks) with network information.
   • Setting up DECwindows for TCP/IP applications.
   • Refining NFS Server (binding disk devices, exporting file systems, adding proxies) and NFS Client (adding proxies, mounting devices) configurations.
   • Making NFS online documentation accessible to remote users.
   • Creating additional BIND Server files as needed.

Finally, the document mentions ongoing steps for network tuning by modifying UCX and SYSGEN parameters. Appendices provide examples of installation and configuration, and a list of installed UCX and PATHWORKS files.
