Hello Michael

Yes it is possible.

It is important to set the correct path and environment variables and a case of MSS or PGS use 64 bit DSN entries for 64 bit Uniface and use 32 bit DSN entries for 32 bit Uniface.

In my environment I use bat scripts to set PATH and other environment variables:

An example with Informix and Oracle:

32 bit

@echo off 
setlocal
set "THEVERSION=104R2w32"
set "UNIFACE_HOME=C:\\uniface\\installations\\%THEVERSION%"
set "PATH=C:\\Program Files (x86)\\MySQL\\MySQL Installer for Windows;%PATH%"
set "PATH=%UNIFACE_HOME%\\common\\bin;%PATH%"
set "CLIENT_LOCALE=en_US.utf8"
set "DB_LOCALE=en_US.utf8" 
set "INFORMIXDIR=C:\\Program Files (x86)\\Informix Client-SDK"
set "PATH=%INFORMIXDIR%\\bin;%PATH%"
set "INFORMIXSERVER=infserver"
set "INFORMIXSQLHOSTS=C:\\Program Files\\IBM Informix Software Bundle\\etc\\sqlhosts.infserver"
set "PATH=C:\\Oracle\\instantclient_19_16;%PATH%"
set "TNS_ADMIN=C:\\Oracle"
set "_EXE=%UNIFACE_HOME%\\common\\bin\\ide.exe"
set "ADM=%UNIFACE_HOME%\\uniface\\adm"
set "ASN=.\\asn\\ide_%THEVERSION%.asn"
set "INI=C:\\uniface\\project\\ini\\unicode%THEVERSION%.ini"
call "%_EXE%" /dir=".." /adm="%ADM%" /asn="%ASN%" /ini="%INI%" ?
endlocal
exit

64 bit

@echo off 
setlocal
set "THEVERSION=104R2w64"
set "UNIFACE_HOME=C:\\uniface\\installations\\%THEVERSION%"
set "PATH=%UNIFACE_HOME%\\common\\bin;%PATH%"
set "CLIENT_LOCALE=en_US.utf8"
set "DB_LOCALE=en_US.utf8" 
set "DBDATE=DMY4"
set "INFORMIXDIR=C:\\Program Files\\IBM Informix Client-SDK"
set "PATH=%INFORMIXDIR%\\bin;%PATH%"
set "INFORMIXSERVER=infserver"
set "INFORMIXSQLHOSTS=C:\\Program Files\\IBM Informix Software Bundle\\etc\\sqlhosts.infserver"
set "PATH=C:\\Oracle\\instantclient_21_7_x64;%PATH%"
set "TNS_ADMIN=C:\\Oracle"
set "_EXE=%UNIFACE_HOME%\\common\\bin\\ide.exe"
set "ADM=%UNIFACE_HOME%\\uniface\\adm"
set "ASN=.\\asn\\ide_%THEVERSION%.asn"
set "INI=C:\\uniface\\project\\ini\\unicode%THEVERSION%.ini"
call "%_EXE%" /dir=".." /adm="%ADM%" /asn="%ASN%" /ini="%INI%" ?
endlocal
exit

Hello Peter,

thanks for your quick response. One additional question:

Can these two "installations" share the same UAR? Or do we have to compile our components with both 32 and 64 bit?

Best regards

Hello Michael

Yes they can use the same uar file.

Perfect... Thank you very much
