PTF IP22973 fixes APAR IC57288

This fix handles the following situation:
The Net Search Extender is able to install
silently using the -s option. But the instance
services are not created.
This fix now ensures that NSE is able to install
silently and create the instance services.

Installation summary on Windows:
================================
1. Stop NSE and DB2
2. Uninstall NSE
3. Reboot the machine
4. Record a response file according to the section 'RECORD MODE' below
5. A file called setup.iss has been created in the specified directory and NSE is propperly installed
6. If you want to use the same settings on a different machine, execute setup.exe in silent mode according 
   to the section 'SILENT MODE' described below.

After that, NSE is installed and the necessary instance services are created.

Installation on Windows - detailed description - please read carefully:
=======================================================================

This method uses some more command-line options provided by
InstallShield. The command-line options that require a parameter
must be specified with no space between the option and its
parameter.

Installation methods:

/r Record mode (records a response file for silent installations)
/s Silent install (runs installation silently)
/x Uninstallation mode (removes current installation)

/f1 Specify alternative response file name (full path)
/f2 Specify alternative setup log file name (full path)

RECORD MODE:

In order to run an installation in silent mode, you first must
run setup.exe /r to generate a response file. All run-time dialogues
are displayed and a file called Setup.iss is stored. By default the file 
will be stored in the directory specified in the environment variable %WINDIR%.
If you want to specify another file name and location, use the /f1 parameter.

Example:

setup.exe /r /f1"d:\some_directory\setup.iss"

SILENT MODE:

In order to run an installation silently, using the same settings you used during
the recording of the setup.iss file, you must run setup.exe with the /s option.

Using the /f1 argument allows you to specify the location of the response
file and the /f2 argument allows to locate the log file name for the setup.

Example:

setup.exe /s /f1"d:\some_directory\setup.iss" /f2"d:\another_directory\mysetup.log"

The Setup.log file for a successful silent installation will look similar to the 
output shown below:

===================================================
[InstallShield Silent]
Version=v6.00.000
File=Log File
[ResponseResult]
ResultCode=0
[Application]
Name=DB2 Net Search Extender
