1.1 Why Migrate?

Migration to RTR Version 3 takes advantage of the new features and improved capabilities of RTR Version 3. These include:

•Improved installation procedure using Polycenter Software Installation Utility (PCSI), not VMSINSTAL

•Interoperability with multiple operating systems including:

OpenVMS (Alpha and VAX)

UNIX (DIGITAL UNIX, SUN Solaris, IBM AIX, HP–UX)

Windows NT

Windows 95 (client only)

•Improved ability to choose a primary server

•Use of more than one other node for a standby server

•Network transport selection (DECnet or TCP/IP)

•New SHOW command screens containing information about transactional messages, resource managers, and some new state names

•New MONITOR pictures

•A new API, the Portable API

•Role clariﬁcation (Requestor changed to Client)

•Compatibility with Version 2 applications (no recompilation or linking required)

•Use of mailboxes instead of OpenVMS cache and global sections for interprocess communication

•Use of OpenVMS quotas, eliminating need for manually sizing conﬁguration parameters

•Enhanced partition management

•Enhanced journal management

•Exception logging

•Support for industry standard protocols for resource managers:
