Earlier I wrote about the automatic or silent install of JDeveloper. As a preperation for an automatic install of the complete SOASuite I translated this to Linux.

To do so in Linux you'll need to adapt the sudoers file.

Log in als root via het commando

[oracle@darlin-vce-db ~]$ su -
Password: 
Last login: Fri Feb 26 06:44:05 EST 2016 on pts/0

Then edit the sudo-ers file:

[root@darlin-vce-db ~]# vi /etc/sudoers

Uncomment the lines for the Cmnd_Alias-es SOFTWARE en SERVICES (remove the hash ’#’ from the start of the lines)

## Installation and management of software
Cmnd_Alias SOFTWARE = /bin/rpm, /usr/bin/up2date, /usr/bin/yum

## Services
Cmnd_Alias SERVICES = /sbin/service, /sbin/chkconfig

Then add the following two lines to the end of the file:

## Extra rights for oracle to do for instance rpm without password.
oracle          ALL=  NOPASSWD: SERVICES, SOFTWARE

Save the file (use an exclamation-mark in the ‘:wq!’ command, since sudoers is a read-only-file.
I separated the settings for the environment in a seperate file, called 'jdev12c_env.sh', so you can use that before starting JDeveloper later on or to add these settings in your profile:

#!/bin/bash
echo set Jdeveloper BPM Quickstart 12cR2 environment
export JAVA_HOME=/usr/java/jdk1.8.0_74
export JDEV_HOME=/u01/app/oracle/JDeveloper/12210_BPMQS
export JDEV_USER_HOME_SOA=/home/oracle/JDeveloper/SOA
export JDEV_USER_DIR_SOA=/home/oracle/JDeveloper/SOA

I adapted the response file because of a different ORACLE_HOME path under Linux and renamed it to 'bpmqs1221_silentInstall-lnx.rsp':

[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
 
#
MOS_USERNAME=
 
#
MOS_PASSWORD=
 
#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
AUTO_UPDATES_LOCATION=
 
#
SOFTWARE_UPDATES_PROXY_SERVER=
 
#
SOFTWARE_UPDATES_PROXY_PORT=
 
#
SOFTWARE_UPDATES_PROXY_USER=
 
#
SOFTWARE_UPDATES_PROXY_PASSWORD=
 
#The oracle home location. This can be an existing Oracle Home or a new Oracle Home
ORACLE_HOME=/u01/app/oracle/JDeveloper/12210_BPMQS

As an extra I also created an start script called 'jdev12c.sh':

#!/bin/bash
. $PWD/jdev12c_env.sh
echo start Jdeveloper BPM Quickstart 12cR2 
$JDEV_HOME/jdeveloper/jdev/bin/jdev

The actual install script is as

#!/bin/bash
. $PWD/jdev12c_env.sh
echo JAVA_HOME=$JAVA_HOME
if [ ! -d "$JAVA_HOME" ]; then
  # Install jdk
  echo Install jdk 1.8
  sudo rpm -ihv ./jdk-8u74-linux-x64.rpm
else
  echo jdk 1.8 already installed
fi
# Install BPM QS
if [ ! -d "$JDEV_HOME" ]; then
  # Install JDeveloper BPM QuickStart
  echo Install JDeveloper BPM QuickStart 12cR2
  $JAVA_HOME/bin/java -jar fmw_12.2.1.0.0_bpm_quickstart.jar -silent -responseFile $PWD/bpmqs1221_silentInstall-lnx.rsp
else
  echo JDeveloper BPM QuickStart 12cR2 already installed
fi
echo copy jdev.boot naar $JDEV_HOME/jdeveloper/jdev/bin
mv $JDEV_HOME/jdeveloper/jdev/bin/jdev.boot $JDEV_HOME/jdeveloper/jdev/bin/jdev.boot.org
cp $PWD/jdev.boot $JDEV_HOME/jdeveloper/jdev/bin/
echo copy JDeveloper BPM QuickStart 12cR2 environment and start scripts to ~/bin
cp $PWD/jdev12c_env.sh ~/bin 
cp $PWD/jdev12c.sh ~/bin

As described in the Windows variant of this install this script copies an adapted version of the jdev.boot file to use the JDEV_USER_HOME_SOA and JDEV_USER_DIR_SOA environment variables as set in the jdev12c_env.sh. Also it copies the jdev12c_env.sh and jdev12c.sh scripts to the ~/bin folder (user home dir), so after install you're good to go by running the jdev12c.sh script for starting JDeveloper.
