I think almost everyone knows how to create a package for IBM functional Tester. But these are the basic things that you need to do while creating a package for that .
1) Create a package that would install the IBM Installation Manager.( Dont worry about the upgrade of Installation managew, becoz the installation would automatically upgrade the package).
2) Create the .xml files for how the installation should happen. The xml file would contain the location of the repository sources and the where the license files are located.
For silent installation this the command line.
C:\Program Files\IBM\Installation Manager\eclipse\IBMIM.exe --launcher.ini silent-install.ini -input "U:\responsefile.xml"
U: drive that is right. U need to map the drive for the installation to happen. The source directory should be mapped first for the installation to happen.
