9. z/TPF migration survey What are we doing now Staff to learn and use CVS/UNIX HFS Get programmers used to TPF Toolkit (IDE) before introducing new debuggers and new library system. Rewriting offline performance reporting tools Migrating SW to Single Source Compliance

10. z/TPF migration survey Big hitters to carry forward Transaction Monitoring/Billing/Collecting Dump Processing (online and offline) Assembler Stack macros Resource Policeman Capture Restore tools

11. z/TPF migration survey Not carried forward System Performance Monitoring tools (replaced with IBM Profiler and CDC) Some debugging tools Step by Step Trace ???

12. z/TPF migration survey Long Term Needs Native SQL database and SQL assembling process (Bind with DB2) IBM continue to pick up enhancement requests Impact of z/TPF on CPU cycles – Solve the longstanding CPU cycles issue

13. z/TPF migration survey Library System Migration Versioning – totally dropping or changing to another scheme Developing tools to ensure accuracy of HFS source to production Retrofitting new scheme to 4.1

14. z/TPF migration survey 64-bit mode Do this later. 2G addressing good enough for now, z/TPF will free up lots of memory

15. z/TPF migration survey Testing Message Capture and Replay Parallel testing of 4.1 and z/TPF systems with user validation of both results New library and build system has to be validated as well
