Introduction

1.1Why Migrate?

•Support for subtransactions or nested transactions Additionally, other considerations are:

•New features will be implemented in RTR Version 3, not in RTR Version 2

•Some software problems will be addressed only in RTR Version 3 and not in RTR Version 2

•Some improved capabilities are already available only in RTR Version 3

•More extensive release test coverage than with RTR Version 2

•RTR Version 3 tested for year 2000 compliance (RTR Version 3.1D, Version 3.2)

•Any residual year 2000 problems will be ﬁxed only in RTR Version 3.1D or later

Other changes introduced with RTR Version 3:

•New format and content of journal to improve security and ﬂexibility of transactional messaging

•Change of shared library name RTRSHR.EXE to LIBRTR.EXE

Note

There is no upgrade path for Windows 3.1 clients; applications must be rewritten using the RTR Version 3 API.

1.2 Goals and Nongoals

The goal of this document is to assist the RTR Version 2 system manager in planning and implementing the migration of an RTR Version 2 environment to RTR Version 3.

It is not a goal of this document to instruct the system manager about RTR or teach troubleshooting or analysis of the RTR environment.

1.3 Reading Guidelines

Read this document, the RTR Version 3 documentation and Release Notes before beginning to implement an RTR migration to RTR Version 3.
