Introduction:Multiple installation of IBM Informix Dynamic Server is now enabled in IDS 11.50 xC2. With this, users will be able to install multiples copies of IDS on a single machine with the ability to create instance(s) per installation. For example, a user can have 11.50 xC1 and 11.50 xC2 co-existing on the same machine with instances related to each installation running on that machine.
With this new effort, a user that has an installation of IDS 11.50 can invoke setup.exe and will be presented with existing installation of IDS on the machine. The user can then make a choice between installing a new copy of IDS and maintaining an (one of the) existing copy(ies). If there is an existing installation of IDS 11.50 on a machine, a user that launches setup.exe in graphical mode will be presented a panel similar to the one below:
However, with an existing installation of IDS 11.50, launching setup.exe in silent mode will require a maintenance response file. Without a maintenance response file or with an installation response file, the installer will abort. To install a subsequent copy of IDS 11.50 in silent mode, the user should pass the ‘-multiple’ command line option to setup.exe.
In addition to the "-multiple" command line option, there are 2 command line options for maintenance namely "-path" and "-instnum". These 2 new command line options are used to launch maintenance mode for a specified installation. Since they perform the same functionality, they should be used interchangeably and not in conjunction with one another.
Usages of the newly implemented options:
This option can be used in conjunction with other installation command line options. E.g.
setup.exe -multiple -s -f1"C:\TEMP\server.ini" -f2"C:\TEMP\server.log"
setup.exe -path [installation path]
The user invokes setup.exe with the ‘-path’ option passing the installation path for which maintenance is required. This option can be used in conjunction with other maintenance command line options. E.g.
setup.exe -path [installation path] -s -f1"C:\uninst.ini"
setup -instnum [installation number]
The user invokes setup.exe with the ‘-instnum’ option passing installation number for which maintenance is required. Note that each installation is tagged with an installation number in shortcut menu (except for the first installation which doesn’t have a tag). This option can be used in conjunction with other maintenance command line options. E.g.
setup.exe -instnum [installation number] -s -f1"C:\uninst.ini"
