[Unattended] Multiple-step setups, problem with "visibility" of new environment variables

Hi all,

I have a problem concerning installation of Ingres RDBMS (for those of
you who don't know it, it's something like MySQL...) client software.

In the moment it looks like this.

todo.pl "%Z%\install\packages\ingresclientservicepack\setup.exe /silent"
todo.pl ".reboot"
todo.pl "%Z%\install\packages\ingresclient\setup.exe /silent"

(The switches are a little bit more complicated in reality, so the
above is somehow simplified...)

The reboot is necessary because the Ingres-Client software defines a
new environment variable II_SYSTEM (pointing to the Ingres
installation path) and the Ingres-Client-Servicepack setup *must see*
that variable in order to run through. If I leave out the reboot, the
service pack installation does not work.

So the question is: how can I achieve in "multiple step" scenarios
that the second step will see environment variables set by the first
step *without* having to reboot?

Regards
Gerhard

well, try to add a path for the user:

set II_SYSTEM=C:\Ingres

|reg add HKCU\Environment /v PATH /d "%II_SYSTEM%;%path%" /f|

Hello Juanjo,

first of all, thanks for your response.

I have setup a little test case based on your suggestion.

***part1.bat***
set II_SYSTEM=C:\Ingres
reg add HKCU\Environment /v PATH /d "%II_SYSTEM%;%path%" /f
***part1.bat***

***part2.bat***
todo.pl "echo %PATH%"
***part2.bat***

***runallwithoutreboot.bat***
todo.pl "part2.bat"
todo.pl "part1.bat"
***runallwithoutreboot.bat***

I have executed runallwithoutreboot.bat using appsonly.bat

Unfortunately, the output of echo command in part2.bat will *not show* c:\Ingres

Logging off from Windows (or rebooting) + logging in + cmd.exe + path command
---> c:\Ingres is shown

So it was worth a trial but doesn't seem to solve the problem.

I wonder if the with-env.pl script would be useful for my scenario,
has anybody here used it and can give some examples?

Regards
Gerhard

Could you please upload the content of this script on the wiki.

with-env.pl is in the SVN trunk:
http://unattended.svn.sourceforge.net/viewvc/unattended/trunk/install/bin/with-env.pl?view=log

Should I upload to the WIKI anyway...?

Have you tried:

todo.pl "ingres-sp.bat"
todo.pl "%Z%\install\packages\ingresclient\setup.exe /silent"

And in your scripts folder, have ingres-sp.bat as follows:

set II_SYSTEM=C:\ingres
%Z%\install\packages\ingresclientservicepack\setup.exe /silent

That should work to enable your service pack installer see the environment variable, it won't last beyond that shell launched for the batch script to run in, but it doesn't need to.

If the variable is in effect a "fixed" path, how about setting the variable before the client is installed ?

http://vlaurie.com/computers2/Articles/environment.htm might be of use
