GOAL

The requirement to use an existing WebLogic Server 10.3.2 for installation of Grid Control 11.1.0.1.0 is a new one for the Grid Contorl product . Herein is provided an example of a simple WLS installation that will serve this purpose.

A step-by-step description with graphical representation of the installer progress is available here.

A complete description of the Weblogic Server 10.3.2 prerequisites, installation options and procedures can be found in the Fusion Middleware section of the Oracle documentation available on OTN:

SOLUTION

A) Prerequisites:

Grid Control 11g uses WebLogic Server instead of OC4J which was traditional with Grid Control versions 10.1 and 10.2.  Grid Control 11g will deploy from an existing Weblogic Server during the Grid Control Installation.

1) Obtain the wls1032_generic.zip for installation of WLS on 64bit platforms.

Note that in the 64bit version of Linux (x86_64), the required jdk for WLS installation is not bundled and additional action on the part of the user is required to access the appropriate java resources. Installation of the jdk is described elsewhere. The version must be 10.3.2 and the WLS base product installer must the the generic type for 64bit installation..

2) Verify a jdk1.6 is available for 64bit WLS installation.
Execution of wls1032_generic.jar will require this jdk.

Software sources for this example:

The jdk 1.6 with java executable is located here: /u02/jdk16/jdk1.6.0_18/bin
The wls source is located here: /u02/wls/wls1032_generic.zip
And the script is executed from the /u02/wls/ directory.

To prepare the Web:Logic Server base product installer, alter the downloaded file accordingly (note: do not unzip the "wls1032_generic.zip" file):

$mv wls1032_generic.zip wls1032_generic.jar

3) An empty directory named "Middleware" is provided for simplicity (this name will be used in the installer).

4) Supporting the Graphical User Interface

If the installation is not being undertaken in a local desktop session, ensure that an X server session is available to support rendering the GUI WLS installer application.
Set the DISPLAY environment variable to point to the X server that will display the installer. The format of the DISPLAY environment variable is:

hostname:display_number.screen_number

Example (C shell):

% setenv DISPLAY test.mydomain.com:0.0

Example (Bourne or Korn shell):

$ DISPLAY=test.mydomain.com:0.0; export DISPLAY

You can test the display by running the xclock program:

$ xclock &

Oracle Application Server requires a running X server during installation only. The frame buffer X server installed with your operating system requires that you remain logged in and have the frame buffer running during installation. If you do not wish to do this, then you must use a virtual frame buffer, such as X Virtual Frame Buffer (XVFB) or Virtual Network Computing (VNC).
For information about obtaining and installing XVFB or other virtual frame buffer solutions, search for "frame buffer" on the Oracle Technology Network site. You can access the site at:

(RE: Oracle??? Application Server Installation Guide/10g Release 2 (10.1.2) for Linux x86/Section 4.9.4)

See this reference to correct other issues with the X server associated with WLS installation:

Note. 973202.1 Weblogic Installation Does Not Start : Unable To Instantiate GUI

5) /tmp Directory Requirements

The installation program uses a temporary directory into which it extracts the files necessary to install the software on the target system.
The files in the temporary directory require approximately 2.5 times the space that is ultimately required for the installation.
If enough room is not available on /tmp, then a temporary location with sufficient space must be provided when installing WLS.


B) Procedure:

1) Start the Installer

Invoke the WLS 10.3.2 installer from the .jar source, referencing the jdk1.6 as in this example (being run from the /u02/wls/ directory in this example):

/u02/jdk16/jdk1.6.0_18/bin/java -d64 -jar /u02/wls/wls1032_generic.jar


2) Welcome

The WLS installation Welcome screen will show after extraction of the source from the .jar file is complete.

Select Next to begin WLS installation.


3) Choose Middleware Home Directory

The Choose Middleware Home Directory screen allows selection of the desired location of the WLS software (note that default places it in the user's home directory).
Select Browse to enter the filepath to the Middleware directory.

Direct the WLS installer to the Middleware directory where WebLogic Server 10.3.2 is to be installed.
This directory does not actually need to be named "Middleware", but wherever the WLS installation goes will be known as the Middleware location.

Example: /u01/app/Middleware/

Select Open on the Middleware Home Directory Selection popup window.

Select Next on the Choose Middleware Home Directory screen to accept the Middleware location into the installer.


4) Register for Security Updates

The Register for Security Updates screen presents to option to register for upcoming security updates.
Accept this option by adding the information requested.
If this option is declined, the user is asked about the certainty of this decision in an Are You Sure? Popup window, to which the "Yes" answer can be given.

In either case, once the desired option is given, select Next to proceed.


5) Choose Install

The Choose Install Type offers a choice between a Typical or a Custom installation.

For Grid Control purposes, choose Typical and then Next.


6) JDK Selection

The JDK Selection screen should show the optional location of the jdk1.6 installations known to the installer. Note that no option is provided for the bundled type. The jdk installed earlier to support 64bit WLS should be selected (it was referenced when the installer was invoked).

Select Next once the jdk 1.6 location is verified.


7) Choose Product Installation Directories

On the Choose Product Installation Directories screen, the user will be presented with the value chosen for the Middleware directory and a default location inside it for the wlserver_10.3 directory. 

The default can be accepted by selecting Next.


8) Installation Summary

The Installation Summary screen will show the default options determined by the user and the disk space required for the wls installation.

Select Next to accept the choices and begin WLS installation.


9) Installation Progress

The WLS installation progress screen shows a progress bar and the name of the file currently being copied.
Note that there is new content in /Middleware.


10) Decline Quickstart for Grid Control Purposes

When the installation is complete, the option to run Quickstart is presented on the Installation Complete screen. 
Quickstart configures an example WLS domain for trial use, so it is not needed for Grid Control.
Uncheck the Run Quickstart option and select Done.


11) Finish:

The .../Middleware directory is now populated with the necessary middle tier software, ready to be configured by the Grid Control OMS installer.
