VSI-I64VMS-REDIS-V0400-0-1-RELNOTES.PDF

This document describes the BETA release of Redis 4.0.0 for OpenVMS (I64 and Alpha systems), provided by VMS Software. Redis is an Open Source, in-memory data structure store used as a database, cache, and message broker.

Key Features Included:

• All in-memory/caching functionalities.
• Lua scripting.
• Publish/subscribe.
• A language-agnostic API, enabling application development in 3GLs like COBOL, FORTRAN, and C.
• Example programs and a benchmarking utility.

Key Features Missing/Limitations:

• No on-disk persistence (planned for future releases).
• Redis clustering and replication functionality is untested.
• Maximum cache size is limited to just under 1GB due to the use of 32-bit pointers (64-bit support is planned).
• Applications storing floating-point data on OpenVMS Alpha must use IEEE floating-point format or perform conversions.

Installation & Requirements:

• Installed via an OpenVMS PCSI kit using PRODUCT INSTALL REDIS.
• Requires post-installation steps: adding Redis startup/shutdown commands to SYSTARTUP_VMS.COM and SYSHUTDWN.COM, and configuring redis.conf.
• Requires specific OpenVMS privileges (e.g., TMPMBX, NETMBX, BYPASS, SYSPRV, DETACH) and increased system quotas (e.g., FILLM, BYTLM, CHANNELCNT).
• System requirements: OpenVMS 8.4-1H1/2L1 Alpha, HP TCP/IP Services V5.7 (MultiNet likely compatible), and HP C V7.3-018 compiler.
• Installation on an ODS-5 enabled file system is recommended.
