Automatic install SOA/BPM QuickStart under Linux

Fri, 2016-02-26 07:51
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 -
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.
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:
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':

Response File Version=


#Set this to true if you wish to skip software updates



#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 oracle home location. This can be an existing Oracle Home or a new Oracle Home

As an extra I also created an start script called 'jdev12c.sh':
. $PWD/jdev12c_env.sh
echo start Jdeveloper BPM Quickstart 12cR2

The actual install script is as
. $PWD/jdev12c_env.sh
if [ ! -d "$JAVA_HOME" ]; then
# Install jdk
echo Install jdk 1.8
sudo rpm -ihv ./jdk-8u74-linux-x64.rpm
echo jdk 1.8 already installed
# 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. -silent -responseFile $PWD/bpmqs1221_silentInstall-lnx.rsp
echo JDeveloper BPM QuickStart 12cR2 already installed
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.

BPM/SOA 12c: Symbolic Filebased MDS in Integrated Weblogic

Tue, 2016-02-02 05:44
In BPM/SOA projects, we use the MDS all the time, for sharing xsd's and wsdl's between projects.

Since 12cR1 (12.1.3) we have the QuickStart installers for SOA and BPM,  that allows you to create an Integrated Weblogic domain to use for SOASuite and/or BPMSuite.

In most projects we have the contents of the MDS in subversion and of course a check out of that in a local svn working copy.

My whitepaper mentioned in this blog entry describes how you can use the mds in a SOA Suite project from 11g onwards.

But how use the MDS in your integrated weblogic? I would expect that some how 'magically' the integrated weblogic would 'know' of the mds references that I have in the adf-config.xml file in my SOA/BPM Application. But unfortunately it hasn't. That is only used on design/compile time.

Now you could just deploy/sync your MDS to your integrated weblogic as you would do to your test/production server and did on 11g.

But I wouldn't write this blog-entry if I did not find a cool trick: symbolic links, even on Windows.

As denoted by the JDEV_USER_DIR variable your (see also this blog entry), your DefaultDomain would be in 'c:\Data\JDeveloper\SOA\system12.\DefaultDomain' or 'c:\Users\MAG\AppData\Roaming\JDeveloper\system12.\DefaultDomain' (on Windows).

Within the  Domain folder you'll find the following folder structure: 'store\gmds\mds-soa\soa-infra'.
 This is apparently the folder that is used for the MDS for SOA and BPM Suite. Within there you'll find the folders:
  • deployed-composites
  • soa
In there you can create a symbolic link (in Windows a Junctions) named 'apps' and pointing to the folder in your svn working copy that holds the 'oramds://apps'-related content. In Windows this is done like:
C:\...\DefaultDomain\store\gmds\mds-soa\soa-infra>mklink /J apps y:\Generiek\MDS\trunk\SOA\soa-infra\apps
The /J makes it a 'hard symbolic link' or a 'Junction'. Under Linux you woud use 'ln -s ...'.

You'll get a response like:
C:\...\DefaultDomain\store\gmds\mds-soa\soa-infra>Junction created for apps <<===>> y:\Generiek\MDS\trunk\SOA\soa-infra\apps
When you perform a dir you'll see:

Volume in drive C is System
Volume Serial Number is E257-B299

Directory of c:\Data\JDeveloper\SOA\system12.\DefaultDomain\store\gmds\mds-soa\soa-infra

02-02-2016 12:06 <DIR> .
02-02-2016 12:06 <DIR> ..
02-02-2016 12:06 <JUNCTION> apps [y:\Generiek\MDS\trunk\SOA\soa-infra\apps]
02-02-2016 12:07 <DIR> deployed-composites
02-02-2016 11:23 <DIR> soa
0 File(s) 0 bytes
5 Dir(s) 18.475.872.256 bytes free
You can just CD to the apps folder and do a DIR there, it will then list the contents of the svn working copy folder of your MDS but just from within your Default Domain.

Just refire your Integrated Domain's DefaultServer and you should be able to deploy your composites that depend on the MDS.

Using SKIP LOCKED feature in DB Adapter polling

Tue, 2016-01-19 04:53
Last few days I spent with describing a Throttle mechanism using the DB Adapter. Today the 'Distributed Polling' functionality of the DB Adapter was mentioned to me, which uses the SKIP LOCKED clausule of the database.

On one of the pages you'll get to check the 'Distributed Polling' option:
Leave it like it is, since it adds the 'SKIP LOCKED' option in the 'FOR UPDATE' clausule.

In my example screendump I set the Database Rows per Transaction, but you might want to set in a sensible higher value with regards to the 'RowsPerPollingInterval' that you need to set yourself in the JCA file:

The 'RowsPerPollingInterval' is not an option in the UI, unfortunately. You might want to set this as a multiple to the MaxTransactionSize (in the UI denoted as 'Database Rows per Transaction').

A great explanation for this functionality is this A-Team blogpost. Unfortunately the link to the documentation about 'SKIP LOCKED' in that post is broken. I found this one. Nice thing is that it suggests using AQ as preferred solution in stead of SKIP LOCKED.

Maybe a better way for throttling is using the AQ Adapter together with the properties

Automatic install of JDeveloper

Wed, 2016-01-06 01:57
A few weeks ago I wrote a little script to do a silent install of SOA/BPM QuickStart.
Yesterday I enhanced the script to also do an automatic install of Java and adapt the environment settings to have the JDeveloper settings specific placed in C:\Data\JDeveloper\SOA.

To run the script you should have the following files placed in one folder (for instance c:\temp\soabpm):
Download the jdk-8u65-windows-x64.exe from here. If you use another version adapt the script below to change the JAVA_HOME as the place where it should be installed and the reference to the installer (jdk-8u65-windows-x64.exe) to the version. The script below ignores any other installation of Java (either an other update of jdk8 or earlier versions).

Using the 'setx' command  (see docs) the JAVA_HOME is explicitly set, and also later on the variables JDEV_USER_DIR_SOA and JDEV_USER_HOME_SOA pointing to C:\Data\JDeveloper\SOA. I picked the jdev.boot from an earlier install adapted the ide.user.dir.var variable as follows:

# The ide.user.dir.var specifies the name of the environment variable
# that points to the root directory for user files. The system and
# mywork directories will be created there. If not defined, the IDE
# product will use its base directory as the user directory.

A copy of this jdev.boot file I placed in the same folder as the script. The scripts sets the FMW_HOME as 'C:\oracle\JDeveloper\12210_BPMQS'. After the install of JDeveloper-SOA/BPM QuickStart, it copies this jdev.boot file to the right place in the FMW_HOME (%FMW_HOME%\jdeveloper\jdev\bin).
Make sure that you have the installer jar files (fmw_12. and fmw_12. unzipped in the same folder. You could have downloaded them in zip files. You can use this script also to do a complete silent install of the JDeveloper Studio Edition, but then use the generic installer downloaded here (Oracle JDeveloper 12c Generic/Others(2.1GB)).

The installBpmQS.bat script is as follows.
@echo off
set JAVA_HOME=c:\Program Files\Java\jdk1.8.0_65
echo setx -m JAVA_HOME "%JAVA_HOME%"
rem Check Java
if exist "%JAVA_HOME%" goto :JAVA_HOME_EXISTS
echo Install %JAVA_HOME%
jdk-8u65-windows-x64.exe /s INSTALLDIR="%JAVA_HOME%"
echo %JAVA_HOME% exists
rem check BPM12.2 QS
set FMW_HOME=C:\oracle\JDeveloper\12210_BPMQS
if exist "%FMW_HOME%" goto :BPMQS_HOME_EXISTS
echo Install %FMW_HOME%
rem echo "Current dir2:" %~dp0
echo "Silent install BPM QuickStart, using response file:" %cd%\bpmqs1221_silentInstall.rsp
"%JAVA_HOME%\bin\java.exe" -jar fmw_12. -silent -responseFile %cd%\bpmqs1221_silentInstall.rsp -nowait
echo %FMW_HOME% exists
if not exist c:\Data mkdir c:\Data
if not exist c:\Data\JDeveloper mkdir c:\Data\JDeveloper
if not exist c:\Data\JDeveloper\SOA mkdir c:\Data\JDeveloper\SOA
rem set JDEV_USER_DIR_SOA and JDEV_USER_HOME_SOA as 'c:\Data\JDeveloper\SOA'
echo set JDEV_USER_DIR_SOA and JDEV_USER_HOME_SOA as c:\Data\JDeveloper\SOA
setx -m JDEV_USER_DIR_SOA c:\Data\JDeveloper\SOA
setx -m JDEV_USER_HOME_SOA c:\Data\JDeveloper\SOA
echo copy jdev.boot naar "%FMW_HOME%\jdeveloper\jdev\bin"
copy jdev.boot "%FMW_HOME%\jdeveloper\jdev\bin" /Y
echo done

For completeness, the content of the response file is:

Response File Version=


#Set this to true if you wish to skip software updates


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 oracle home location. This can be an existing Oracle Home or a new Oracle Home
Save this as bpmqs1221_silentInstall.rsp. If you use this for the installation of JDeveloper Studio Edition or any other version of JDeveloper, then adapt the name, also in installBpmQS.bat above, and adapt the FMW_HOME/ORACLE_HOME in both installBpmQS.bat and the response-file.

I could have enhanced this script to put the possible points to change in variables. But I think with my eloboration you should get the point...
