3.2 Silent Mode Installation of the eG Manager and Agents
Silent mode installation is a standard way to ensure repeatability of the installation process.
Administrators use this process when installing the same software in multiple locations/servers.
Usually, the process of a silent install involves saving all the configurations/inputs provided and
reapplying these during subsequent installation without human intervention. The key advantages of a
silent install are repeatability, and the prevention of human errors that may occur during manual
installation.
3.2.1 Silent Mode Installation of the eG Manager
The first step towards installing the eG manager in the silent mode is to create the silent mode script
for a manager installation. The script file will carry the extension .iss, and will contain the inputs
provided by the administrator while installing the eG manager in the normal mode. Before attempting
script creation, ensure that the eGManager_.exe is available on the local host. Then, to create the
script, do the following:
1. From the command prompt, switch to the directory in which the eGManager_.exe resides.
2. Next, issue the following command: eGManager_.exe -a -r /f1””. For
example, to create a script file named eGManager.iss in the c:\script directory, the command should
be: eGManager_.exe -a -r /f1”c:\script\eGManager.iss”.
3. The Normal mode manager installation will then begin. The inputs supplied during the normal
mode will automatically be saved in the iss file that was created in step 2. Refer to the eG
Installation Guide for the detailed procedure for installing an eG manager on Windows in the
normal mode.
The next time you wish to install the eG manager on the same host, you can do so in the Silent mode,
following the steps given below:
1. Uninstall the eG manager on the host (if it already exists).
2. Ensure that the eGManager_.exe is present on the host, go to the command prompt, and then
switch to the directory containing the manager executable.
3. From that directory, execute the following command to install the eG manager in the silent mode:
eGManager_.exe -a -s /f1””. In other
words, to extract installation inputs from the eGManager.iss file that was created in our example
above, the command will be: eGManager_.exe -a -s /f1”c:\script\eGManager.iss”.
4. The eG manager installation will then begin and proceed in the silent mode. Setup will extract the
required inputs from the iss file specified in step 3 above and perform the installation
automatically, requiring no user intervention of any kind.
