How to install BWC in silent mode / do an unattended install?
================================================

While performing silent installation using the option:  -options &ltresponsefile>, the value for &ltresponsefile> must be absolute path and not a relative one. Also, using the response file, the installer can be run in GUI or Silent mode. Please find the steps for different modes below:

- GUI mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-suite_5.3.0_win_x86.exe -a -options C:\temp\bwc_inst_resp
- GUI & Debug mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-suite_5.3.0_win_x86.exe -a -options C:\temp\bwc_inst_resp -is:javaconsole -log #
NOTE: By running in GUI mode, you will be able to verify that the values from response file are properly prefilled in all the panels.

While doing installation in silent mode make sure to comment or remove the line "-silent" in the response file -

- Silent mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-suite_5.3.0_win_x86.exe -a -options C:\temp\bwc_inst_resp -is:silent -silent
- Silent & Debug mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-suite_5.3.0_win_x86.exe -a -options C:\temp\bwc_inst_resp -is:silent -silent -is:javaconsole -log #

I have successfully installed BWC 5.3.0 on my local machine using silent mode option. I have attached a sample copy of the file (bwc_inst_resp) for your reference. Please let me know if this helps.

How to install BWC FT/HA setup in Silent mode with a response file?
=======================================================

These steps were carried out using BWC 5.3 with Oracle 9.2 and it should be not much different for BWC 5.4 or other DB systems.

On Machine1 I have installed Primary Server using Silent mode and then on Machine2 installed Secondary Server similar silent mode.

Machine1:

Downloaded/copied "TIB_bwc-suite_5.3.0_win_x86.exe" to temp folder and ran this command.
C:\temp&gtTIB_bwc-suite_5.3.0_win_x86.exe -a -options c:\temp\bwc_inst_resp_bwcserver1 -is:silent -silent -is:log c:\temp\server1.log

Machine2:

Downloaded/copied "TIB_bwc-suite_5.3.0_win_x86.exe" to temp folder and ran this command.
C:\temp&gtTIB_bwc-suite_5.3.0_win_x86.exe -a -options c:\temp\bwc_inst_resp_bwcserver2 -is:silent -silent -is:log c:\temp\sec.log

First installed on Machine1 then tested starting and stopping BWC server that was successful and also tested using BatchRegistry + PCGUI. All worked.
Then installed on Machine2, started and stopped BWC server and also tested using BatchRegistry + PC GUI.

I have also made these servers part of SERVER_GROUP and it works as expected.

Oracle table also shows both servers:
SQL> select server_name from server_names;

SERVER_NAME
--------------------------------------------------------------------------------
bwc53_server1
bwc53_server2

Please find attached "bwc_inst_resp_bwcserver1" (Machine1) and "bwc_inst_resp_bwcserver2" (Machine2) that I have used to install BWC 5.3 in silent mode.

I have also tested installing Additional BWC 5.3 server on unix using silent mode option with response file and it works.
Please find attached response file i have used - "bwc_inst_resp_bwcserver2_unix"

$ bwworkflow.5.3.0-suite_linux24gl23_x86.bin -options /home/user1/bwc_inst_resp_bwcserver2_unix -is:silent -silent -is:log /home/user1/sec.log
