01.a. Installation of WebLogic Server 12c on Unix and Linux platforms


The beginning of the WebLogic Administration practical work with installation of WebLogic software. Before you began, you must aware per-requisites for installation and also how you can proceed for the installation.  This blog post is specially for newbies who just began learning WebLogic.

Determining supported configurations for WebLogic Server


Software requirements
There are many Java vendors according to your platform you need to select specific Java. every WebLogic release version is publishing a certificate matrix which will tell you what platform versions it support and which JDK version you need to use for WebLogic installation.
  • Sun/Oracle HotSpot JDK
  • Oracle JRockit
  • IBM JVM
  • HP JDK
Example Certificate Matrix Reference
WebLogic 12.1.3 certificate matrix

Hardware Requirements
  • 512 MB RAM
  • 20 GB HDD
  • CPU 300 MHz
  • i3 or above processors Amd

Installation modes

WebLogic server 12c can be installed in two ways
  • Silent mode installation
  • GUI mode installation

WebLogic 12.1.3 silent mode installation on Ubuntu

1. What is silent mode installation? And why?
This is the initial setup required to learn WebLogic Administrator. If you unable to do silently you are unfit for the production environment setup. Silent-mode installation allows us to define an installation configuration only once and then use the configuration to duplicate the installation on many machines. During installation in silent mode, the installation program reads the inputs for desired settings up configuration from an silent response file that you must prepare before beginning the installation. The installation program does not display any configuration options during the installation process. Silent-mode installation works on both Windows and Linux and UNIX systems also.

WebLogic 12c silent mode installation

Major Benefits
  • Less time of execution of installation process 
  • Cloud ready platforms use this method most often
  • This process can be used in configuration tools such as chef, puppet etc 
  •  Easy to install in multiple machines/Production environments
  •  No need of X11 or Mouse clicks!!
Java Installation
Step 1: JDK installation

You can download JDK from Oracle Technical Network (OTN)  Link
 We have two choices to install JDK on a Linux platform:
1. Common for any Linux platform: tar.gz file
tar -zxvf /u01/app/software/jdk*.gz

 

2. Alternative in the Ubuntu box as follows:
To install WebLogic server in silent mode installation first we have to install JDK in the Ubuntu.
  1. sudo add-apt-repository ppa:webupd8team/java
  2. sudo apt-get update
  3. sudo apt-get install oracle-java7-installer
Step 2: Set Environment variables in bash profile
export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export PATH=$PATH:$JAVA_HOME/bin
export MW_HOME=/u01/app/oracle/fmw/oraclehome
export WL_HOME=$MW_HOME/wlserver
export CLASSPATH=$WL_HOME/server/lib/weblogic.jar:.

alias wlst="$MW_HOME/oracle_common/common/bin/wlst.sh"
Step 3:Download WebLogic server 12.1.3 Generic file from download link.

Steps involved in silent mode installation

Step 4:Create a directory “silent” and copy the wls.jar file to this directory. mkdir silent
Step 5:Go to the silent directory by using cd silent/
Step 6:Create a file oraInst.loc file in silent directory as follow as: vi oraInst.loc And insert inventory location and installation group as follow as
Inventory_loc=/u01/app/oracle/silent/oraInventory/
Inst_group=oinstall
Step 7:Create response file and insert below things in the response file
[ENGINE]
Response File Version=1.0.0.0.0
[GENERIC]
ORACLE_HOME=/u01/app/oracle/fmw/oraclehome
INSTALL_TYPE=WebLogic Server
MYORACLESUPPORT_USERNAME=
MYORACLESUPPORT_PASSWORD=
DECLINE_SECURITY_UPDATES=true
SECURITY_UPDATES_VIA_MYORACLESUPPORT=false
PROXY_HOST=
PROXY_PORT=
PROXY_USER=
PROXY_PWD=
COLLECTOR_SUPPORTHUB_URL=

You could edit the ORACLE_HOME as you change versions and also

There could be multiple options for INSTALLATION_TYPE:

  1. WebLogic Server
  2. Coherence
  3. Complete with Examples
  4. Fusion Middleware Infrastructure [Infrastructure domains]
  5. Fusion Middleware Infrastructure with Examples [for Restricted JRF, EM domains]


Please remove the 15 line  that is  two tags

Step 7: Go to the wls.jar location ie in silent directory and insert the following command

java -jar /u01/app/software/fmw_12*_wls.jar \
-silent -invPtrLoc /u01/app/oracle/silent/oraInst.loc \
-responseFile /u01/app/oracle/silent/responsefile.rsp


Step 8: Check WebLogic server is installed in mention location or not

Conclusion 


 Easy once you worked on this procedure you can work on SOA, OSB, ADF and any Oracle Fusion Middleware products.
The above work is for 12.1.3 version which is older version of 12c!

WebLogic 12.2.1 installation in silent mode

The latest version of 12c is 12.2.1.0.0 lets enjoy the new features of WebLogic on Vagrant box here I am executed the installer without matching the certificate matrix. So two of them are not satisfied

  1. Ubuntu Linux
  2. JDK 1.8.0_51 is expected provided 1.8.0_45 

oracle@mydev:/u01/app/software$ java -jar fmw_12.2.1.0.0_wls.jar -silent -invPtrLoc /home/oracle/silent/oraInst.loc -response /home/oracle/silent/responsefile.rsp
Launcher log file is /tmp/OraInstall2015-10-30_01-30-57AM/launcher2015-10-30_01-30-57AM.log.
Option "-response" is deprecated; use "-responseFile" instead.
