Installing Converged Application Server Using the Silent Installation

Silent mode is a way of setting installation options once and then using those settings to duplicate the installation on many machines. The installation program reads your settings from a Response File that you create before you begin installation. The installation program does not display any options during the installation process.

About the Response File

The entries in the Response File (response.rsp) correspond to the prompts that you would see if you used GUI mode.

Incorrect entries in response.rsp can cause installation failures. To help you determine the cause of a failure, Oracle recommends that you create a log file when you start the installation.

The following shows a sample version of a response.rsp file. Your input may be slightly different, depending on your installation.

[ENGINE]

#DO NOT CHANGE THIS.
Response File Version=1.0.0.0.0
 
[GENERIC]
 
#Set this to true if you wish to skip software updates
DECLINE_AUTO_UPDATES=true
 
#My Oracle Support User Name
MOS_USERNAME=
 
#My Oracle Support Password
MOS_PASSWORD=<SECURE VALUE>
 
#If the Software updates are already downloaded and available on your local system, then specify the path to the directory where these patches are available and set SPECIFY_DOWNLOAD_LOCATION to true

#The federated oracle home locations. This should be an existing Oracle Home. Multiple values can be provided as comma seperated values

#Set this variable value to the Installation Type selected. e.g. Converged Application Server, Complete with Examples.
INSTALL_TYPE=Converged Application Server

Returning Exit Codes to the Console

The silent installation program generates exit codes that indicate the success or failure of the installation.

Table 5-1 Installation Program Exit Codes

Code	Description
0	Installation completed successfully.
-1	Installation failed due to a fatal error.
-2	Installation failed due to an internal XML parsing error.

If you start the silent installation process from a script, you can have these exit codes displayed to the console. Example 5-1 shows a sample command file that runs the WebLogic Platform installation while in silent mode and echoes the exit codes to the console from which the script is executed.

Example 5-1 Return Exit Codes

#!/bin/bash
 
# Execute the installer in silent mode
java -jar occas_generic.jar -silent -responseFile /home/user/bin/response.rsp
 
exit_code=$?
 
echo "exit code = ${exit_code}"

echo 'Exit Code Key'
echo '---------------'
echo ' 0 = Installation completed successfully'
echo '-1 = Installation failed due to a fatal error'
echo '-2 = Installation failed due to an internal XML parsing error'

Running the Installer in Silent Mode

To perform a silent installation:

Log in to the target system.
Download the Converged Application Server software from the Oracle software delivery website at:

http://edelivery.oracle.com
Create a response file, as described in "About the Response File".
Go to the directory where you downloaded the Converged Application Server software.
Start the installer by entering the following command:
```
java -jar occas_generic.jar -silent -responseFile ResponseFile
```
The installer checks for all required software and writes errors to a log file if it detects any missing or unavailable components, or if there are any connectivity-related issues.
Check whether the installer completed successfully by retrieving the exit codes, as described in "Returning Exit Codes to the Console".
