32bit vs 64bit

[wvdheiden]

Hi All

Here is a small resume for all people struggling with Rhapsody on Windows systems.

What Windows Version?
NO: Windows 95, 98, ME, 2000, NT
NO More: Windows XP
Rather not: VISTA
Prefered: Windows 7
Not yet (but probably never): Windows 8
Not yet (but maybe): Windows 8.1
Feeling lucky (but you won't be): Windows 10
REALLY?: Linux, but you are on your own. Use a VM instead.

What bitsize of Windows
32-bits: Yes
64-bits: OK but be careful

What bitsize of Rhapsody
32-bits: Yes
64-bits: Don't please

What bitsize of Java
32-bits: Yes
64-bits: OK but it won't help, install 32-bit as well

The risk free Rhapsody installation:
- Install the 32-bit developer in a user defined path (e.g c:\DevTools) where path names are short and do NOT contain other characters then A to Z, 0 to 9 and -_ (dash, underscore, NO Spaces, NO special characters) Then tick "install all files in one location".

I use 64-bit Rhapsody on Windows 7 without any problem.
I build for 32-bit targets (cpu = x86).
I've always installed to a single folder too (eg: C:\Rhapsody810).
I've also used Linux but I agree that Windows is better for Rhapsody.
Are these official IBM predictions?

Hi

First: this is not an official IBM statement.
Rhapsody64 lacks support for some more or less important features:

Abstract
Features listed in this document are not available in the Windows 64-bit version of IBM Rational Rhapsody version 8.0.3 and later.

Content
Limitations in the Windows 64-bit version of Rational Rhapsody 8.0.3 and later
Action language
Code-centric workflows:
Rational Rhapsody Architect for Software
Reverse engineering
Code respect/advanced roundtrip
Code-centric settings
Rational System Architect import
Reverse engineering and roundtrip in Rational Rhapsody in C#
Source Code Control (SCC) configuration management (CM) integration (SCC depends on CM tool support of 64-bit):
Rational ClearCase SCM interface
Rational Team Concert (only in Platform integration Eclipse)
Rational Synergy
Microsoft Visual Source Safe
Wind River Workbench 3.3

Not supported
Internal interface to Rational DOORS
Rational Rhapsody ReporterPlus (as of Rational Rhapsody 8.1)
TeamCenter integration
Tornado IDE
Visual Basic for Applications (VBA)
Webify (web-enabling a Rational Rhapsody model)

That is why I did not recommend Rhapsody64.

Rhapsody 8.1.2 now has 64-bit support for ReporterPLUS.
(fwiw I think ReporterPLUS has essentially been superseded anyway by the Rational Publishing Engine).

What is it exactly that you dont like? Just curious - Ive found the 64-bit version of 7 to be fantastic so far. It has the driver compatibility of Vista, but runs on less resources.

This is an old post. Most of it is caught up by time now.
Statement on January 1, 2020: Use 64-bit wherever you can.

The only f=drawback on Rhapsody is that the Roundtrip and Reverse Engineering have flaws since they are still running on 32-bit and called via some tricks. The rest all works. Even the last flaws will be solved in Rhapsody v9.

PS
I would stop using Windows 7 now (Although I liked it more than w10) Microsoft stopped the support for it. (Or will someday now)
