Ok, I have discovered that this is a question of decimal separator. My Windows system has by default Polish reginal settings, where the decimal sparator is "," opposite to "." for English. When I send the same Envelope with float values in format required by Tuxedo it works OK. But the question arises : how to change the Tuxedo to require other format ? The changing of regional settings to English does not work ? Does it reads them only during installation ?
This is a known issue and has been fixed in SALT. Unfortunately it was fixed in SALT 1.1 and not propagated to the latest SALT version yet. I am not quite sure which version you are using. If you already bought SALT, you may ask your Oracle support person to ask a patch with fixing propagation. You can also work around this by,
Set the following registry key before starting Tuxedo.
Thank again for you help !
This is my test/development environment. The target one will be on i5/i6/AIX so I will need to come back to the problem once again when the system will be about to run the pre-production tests.
