Preparing for installation
• Type of installers
Installation Type Description
OS-specific Package installer
This type of installer is a standalone version of the installation program
that includes the JDKs for the selected platform. The installer may be
either an .exe file or a .bin file, depending on the selected platform
Note: Silent mode installation is supported only for Package installers.
Generic Package installer
This type of installer is a .jar file. It does not include the JRockit SDK and
Sun JDK. We can use this type of installer to install the product on any
supported platform on which Java is already installed.
Upgrade installer
Upgrade installers allow us to upgrade an existing WebLogic Server
installation to the current patch release.
Since WebLogic Server 12.1.1 is a new major release, there is no upgrade installer for this release.
Development-only and supplemental installers
The development-only installer is a ZIP file that we extract to a
Middleware home directory to create a WebLogic Server installation. It
contains a WebLogic Server installation that includes all of the artifacts
needed for development.
We must not use this for WebLogic Server installation for production. This is also available to provide additional features, such as
server examples, for a development-only installation.

Product Distribution
The WebLogic Server installers are distributed in the following ways:
 WebLogic Server installation DVD
 Download from the Oracle Software Delivery Cloud website at http://edelivery.oracle.com/.
Only the OS-specific Package installers and Generic Package installers are available from this site; Upgrade
installers are not available here. These files are downloaded as ZIP files.
 Download from the Oracle Technology Network Web site.
The OS-specific Package and Generic Package installers are available from this site; Upgrade installers are
not available here. The downloaded file is a .bin, .jar, or .exe file, depending on your platform.

Installation Prerequisites
 System Requirements
 WebLogic Server Installation User
 Before we start the Installation program
 Temporary Disk Space Requirements
 Administrator Privileges
 About Installing Node Manager as a Windows Service.

System Requirements
Component Requirement
Processor 1-GHz CPU
Hard disk drive
A complete installation (including SDKs) requires approximately 3.9 GB of disk space.
This includes temporary disk space that is needed during installation. Depending on the
components you choose to install, and the installer that you are using, less disk space
may be needed.
Memory A minimum of 1 GB RAM, although Oracle recommends 2 GB of RAM.
Color bit depth display
For graphical-mode installation, 8-bit color depth (256 colors) is required. For console-mode
and silent-mode installation, there is no color bit depth requirement.
JDK
The installation program requires a JRE to run. A JRE is bundled in the Windows 32-bit
and Linux x86 installation programs, as well as in some UNIX installation programs
(those with file names ending in .bin).For other platforms, the installation program
does not install a JDK. File names for these installation programs end in .jar. To run the
.jar installation programs, we must have the appropriate version of the JDK installed on
our system, and include the bin directory of the JDK at the beginning of the PATH
variable definition.
Note: It is important that we use a JDK because the installation process assigns values to JAVA_HOME and related
variables to point to the JDK directory. All scripts installed by the installation program use this JDK by default,
including scripts to start sample applications, the Configuration Wizard, and other development tools.

WebLogic Server Installation User
 If we are using the Generic Package installer or the Linux 64-bit installer, Oracle recommends that to set umask to 027 on our
system prior to installation. This ensures that WebLogic Server file permissions will be set properly during installation. We can
use the following command:
umask 027
We must enter this command in the same terminal window from which you plan to run the WebLogic Server installer.
 When installing WebLogic Server on a UNIX or Linux operating system, do not run the installation program as the root user.
 When using a WebLogic Server(WLS) Upgrade installer to upgrade an existing WLS installation on Linux or UNIX operating
systems, we must run the Upgrade installer using the same user ID as was used to perform the initial WLS installation.
 On Windows systems, if we want the option to create the Start menu shortcuts in the All Users folder, or in the Local User's
Start menu folder, we must use an account that has administrator privileges when you log in to the target system.

Before We Start the Installation Program
 Before we start installation If we are using the Generic Package installer or the Linux 64-bit installer, Oracle recommends that
to set umask to 027 on our system prior to installation. This ensures that WebLogic Server file permissions will be set properly
during installation. We can use the following command:
umask 027
 If we are installing the software in graphical mode on a UNIX or Linux machine, we must set the DISPLAY environment
variable before running the installer.
 If we want to use WebLogic Server with JDK 7, we must make sure to implement the changes that supports WLS installation.
 If we are using a .jar installer, replace JAVA_HOME with the installation location of the supported JDK we installed for our
platform.
 Make sure that we are installing our product on a supported hardware or software configuration.
 We cannot reinstall a product on top of a previously installed version of the same product, either in the same Middleware
home directory or in the same file location.
We can, however, add products and product components to an existing installation and can also install patches to an
existing installation using an Upgrade installer or Smart Update.
 If we are adding components to an existing installation of WebLogic Server, we should shut down any running servers before
starting the installation.

Temporary Disk Space Requirements
The installation program uses a temporary directory into which it extracts the files that are needed to install the software on the
target system. During the installation process, our temporary directory must contain sufficient space to accommodate the
compressed JRE bundled with the installation program.
By default, the installation program uses the following temporary directories:
 Windows platforms—directory referenced by the TMP system variable
 UNIX platforms—system-dependent temporary directory
Note: If we do not have enough temporary space to run the installation program, we are prompted to specify an alternate
directory or exit the installation program.
Setting Up the Temporary Directory
Platform Procedure
Windows
Do one of the following:
1) Set the TMP system variable to a directory of your choice.
2) If you run the installation program from the command line, include the
-Djava.io.tmpdir=tmpdirpath option, replacing tmpdirpath with the full path of the directory you
want to designate as a temporary storage area for the installation program.
Eg : wls1036_win32.exe -mode=console -Djava.io.tmpdir=C:Temp
UNIX
Enter the following option on the command line when we start the installation :
-Djava.io.tmpdir=tmpdirpath
Here, tmpdirpath is the full path of the directory we want to designate as a temporary storage area for the
installation program.

Administrator Privileges
• On Windows systems, if we want the option to create the Start menu shortcuts in the All Users folder, or in
the Local User's Start menu folder, we must use an account that has administrator privileges when you log
in to the target system.
Available Shortcut Options
Option Behavior
All Users
All users registered on the machine are provided with access to the installed software.
Subsequently, if users without administrator privileges use the Configuration Wizard from this
installation to create WebLogic domains, Start menu shortcuts to the domains are not created. In
this case, users can manually create shortcuts in their local Start menu folders, if desired.
Local User
Other users registered on this machine do not have access to the Start menu entries for this
installation
If a user without administrator privileges installs the software, the Start menu entries are created in the user's local Start menu
folder.

About Installing Node Manager as a Windows Service
When installing your software on a Windows platform, we can optionally install WebLogic Server Node
Manager as a Windows service.
The WebLogic Server Node Manager is used to:
 Start and stop server instances—both Administration Servers and Managed Servers—remotely.
 Monitor the self-reported health of servers and automatically kill server instances whose health state is
FAILED.
 Migrate servers in a WebLogic Server cluster.
 Automatically restart servers that have the "failed" health state, or have shut down unexpectedly due to a
system crash or reboot.
In a multi-machine environment, we must install Node Manager on each machine that hosts Managed Server
and Administration Server instances of WebLogic Server.
To install the Node Manager Windows Service during an initial installation, we must select a Custom
installation.
• Note: When installing in silent mode, we do not specify a Custom installation. Set the
INSTALL_NODE_MANAGER_SERVICE data-value to yes to install the service.
If we do not install the service during the initial installation, we can install it after installation using the
installNodeMgrSvc.cmd command. We can also uninstall it at any time using the uninstallNodeMgrSvc.cmd
command.

Selecting Directories for Installation
During the installation process, we must specify locations for the following home directories:
 Oracle Fusion Middleware
 WebLogic Server, Coherence (if applicable)
The user_projects directory is not present until we create our first WebLogic domain.

Middleware Home Directory-Considerations
• When we are installing WebLogic Server, we are prompted to choose an existing Middleware home(MW_HOME) directory or
specify a path to create a new Middleware home directory.
• MW_HOME directory servers as a repository (central support directory )for common files that are used by multiple Fusion
Middleware products installed on the same machine.
• The files in the Middleware home directory are essential to ensuring that WebLogic Server operates correctly on your system.
They facilitate checking of cross-product dependencies during installation.
Middleware Home Considerations
 Do not include spaces in the name of your Middleware home directory. CLASSPATH may not be resolved if the name of the
directory contains spaces.
 We can install only one instance of each version of a WebLogic Server product in a single Middleware home directory.
 If we need to maintain separate versions of WLS on the same machine, each version must be in its own Middleware home
directory.
The directories in the Middleware home directory vary depending on the installer that we are using and the products we selected
for installation.

Multiple Home Directories Scenarios
We may need to maintain multiple Middleware home directories in the following situations:
 We may prefer to maintain separate development and production environments, with a separate product stack for each.
With two directories, we can update our development environment without modifying the production environment until we
are ready to do so.
 We may want to maintain two different versions of WebLogic Server at the same time.
Note: We do not have to create a second Middleware home directory when using an Upgrade installer to upgrade an existing
WebLogic Server installation to the current patch release.
 The registry.xml file in our WebLogic Server installation is corrupted.
 After installation, the shared modules directory would contain multiple versions of one or more of the same third-party
products.

Installation Modes
 Graphical mode
Graphical-mode installation is an interactive, GUI-based method for installing our software. It can be run on both Windows and
UNIX systems.
 Console mode
Console-mode installation is an interactive, text-based method for installing our software from the command line, on either a UNIX
system or a Windows system.
 Silent mode
Silent-mode installation is a non-interactive method of installing software. We must use an XML properties file to specify the
installation options. We can run silent-mode installation from either a script or from the command line. Silent-mode installation
allows us to define the installation configuration only once, and then use that configuration to duplicate the installation on many
machines.

Type of Installation
When performing a graphical mode or console mode installation, the installation program provides two types of installation
1. Typical
2. Custom
Typical
In a Typical installation, most of the components that are included in the installation program are installed.
Custom
In a Custom installation, we can choose the software components you want to install on our system.
Sample domains preconfigured to use the Derby database are created only for the installed components.
On Windows and Linux systems, two JDKs are installed:
 JRockit 1.6.0 JDK
 Sun JDK 1.6.0

Generating a Verbose Installation Log
If we launch the installation from the command line or from a script, we can specify the -log option to generate a verbose
installation log. The installation log stores messages (informational, warning, error, and fatal) about events that occur during the
installation process. This type of file can be especially useful for silent installations.
Unless a fatal (irrecoverable) error occurs, the installation program completes the installation successfully.
To create a verbose log file during installation, include the -log=full_path_to_log file option in the command line.
For example, to create a verbose log file for the WebLogic Server Package installer for Windows, enter:
wls1034_win32.exe -log=C:logsserver_install.log
The path must specify a file. We cannot create a folder simply by including a name for it in a pathname; our path should specify
only existing folders.

GUI Mode Installation
In order to run the installation program in graphical mode, the console attached to the machine on which we are installing the
software must support a Java-based GUI. All consoles for Windows systems support Java-based GUIs, but not all consoles for UNIX
systems do. If we attempt to start the installation program in graphical mode on a system that cannot support graphical display,
the installation program automatically starts in console mode.
Starting the Installation Program in Graphical Mode on Windows
1. Log in to the Windows system.
2. Go to the directory that contains the installation program
3. Double-click the installation file.
Starting .bin Installation Programs in Graphical Mode on UNIX Machines
1.Log in to the target UNIX system.
2.Go to the directory that contains the installation program.
3.Launch the installation by entering the following commands:
chmod a+x file_name.bin
./file_name.bin
If we plan to install the Server Examples, you must include the following parameter in the installation command. Otherwise, the
installation may take longer than expected.
-Djava.security.egd=file:/dev/./urandom

Continued…
Starting .jar installation Programs in Graphical Mode
1.Log in to the target system.
2.Add the directory of the appropriate JDK to the PATH variable definition on the target system. For example, on UNIX or Linux
systems, add the bin directory to the beginning of the PATH variable:
PATH=$JAVA_HOME/bin:$PATH; export PATH
3. Go to the directory where you downloaded the installation program
4. Launch the installation program by entering the following command (this example shows the Generic installer):
java -jar wls1036_generic.jar ( -mode=console (for console mode))

Continued…
Installing WebLogic Server on 64-Bit Platforms Using a 64-Bit JDK
If we are installing WebLogic Server on a 64-bit platform using a .jar installation program:
Add the directory of the appropriate JDK to the PATH variable definition on the target system. For example, on UNIX, add the bin
directory of the appropriate 64-bit JDK to the beginning of the PATH variable definition on the target system:
JAVA_HOME=path_to_64-bit_JDK; export JAVA_HOME
(UNIX or Linux only) Include the -d64 flag in the installation command when using a 32/64-bit hybrid JDK (such as for the HP-PA,
HPIA, and Solaris64 platforms). For example, if installing in graphical mode using the Package installer:
java -d64 -jar wlsversion_generic.jar ( -mode=console (for console mode))
Run the java -version command (or java -d64 -version command on UNIX or Linux platforms using a 32/64-bit hybrid JDK) to
ensure that your JAVA_HOME refers to a 64-bit JDK.
If we are using the Sun 64-bit JDK, use the following command to install WebLogic Server:
java -Xmx1024m -jar wlsversion_generic.jar ( -mode=console (for console mode))

Console Mode Installation
When installing WebLogic Server in console mode, respond to the prompts in each section by entering the number associated with
your choice or by pressing Enter to accept the default. To exit the installation process, enter exit (or x) in response to any prompt.
To review or change your selection, enter previous (or p) at the prompt. To proceed to the following window, enter next (or n).
Starting the Installation Program in Console Mode on Windows
1. Log in to the target Windows system.
2. Open a command prompt window.
3. Go to the directory that contains the installation program.
4. Launch the installation by entering the name of the installation program. For example, to start the WebLogic Server Package
installer for Windows in console mode, enter
wls1036_win32.exe -mode=console
Starting .bin Installation Programs in Console Mode
1. Log in to the target UNIX system.
3. Launch the installation by entering the following commands:
./file_name.bin -mode=console

Silent-Mode Installation
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 settings for our configuration
from an XML file that we create 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 UNIX systems.
Overview of Silent-Mode Installation Steps
The silent-mode installation process has two primary steps:
1. Create a silent.xml file that defines the installation configuration that you would normally enter during an interactive
installation process, such as graphical-mode or console-mode installation. For example, in silent.xml, we can supply the values
for the Middleware home directory, the product directory, and the components to be installed.
2. Start the silent-mode installation that is appropriate for below situations:
Starting the Installation Program in Silent Mode on Windows
Starting .bin Installation Programs in Silent Mode
Starting .jar installation programs in Silent Mode

Considerations for Silent-Mode Installation
• Silent-mode installation requires the same amount of temporary disk space and uses the same temporary storage directories
as a standard installation. The installation program does not alert us if there is not enough space in the temporary directory.
• A silent-mode installation takes the same amount of time as a standard installation.
• At the beginning of a silent-mode installation, an initial installation program window or message is displayed briefly,
indicating that the installation has started. No messages are displayed to indicate that the installation is in progress or has
completed successfully.
• Incorrect entries in the silent.xml file can cause installation failures. To help us determine the cause of a failure, Oracle
recommends that you create a log file when we start the installation.
• The XML definition (<?xml version="1.0" encoding="UTF-8"?>) must be at the very beginning of the silent.xml file. Do not
enter a space or line breaks before the XML definition.
• We cannot reinstall any WebLogic product on top of a previously installed version of the same product—in the same
Middleware home directory or in the same file location. To reinstall the same version of a product, you must first uninstall the
previously installed instance of it or install the new instance in another location.
• However we can add products and product components to an existing installation

Creating a silent.xml File for Silent-Mode Installation
• Before you can run the installation program in silent mode, you must first create a silent.xml file. Since, the installation
program uses an XML file (silent.xml) to determine which installation options should be implemented.
To create a silent.xml file:
1. Copy the sample code provided and paste the code in an XML file.
2. Save the file, with the name silent.xml, in the same directory that contains the installation program.
3. In the silent.xml file that we saved on your system, edit the values for the data-value names to reflect our configuration.
We must follow XML guidelines for characters when modifying values. So, we cannot use characters reserved for use in XML, such
as <, >, [, and ].

Starting Silent Mode Installation
Starting the Installation Program in Silent Mode on Windows
1) Log in to the Windows system
2) Create a silent.xml file that defines the configuration settings
3) Open a command prompt window
4) Go to the directory that contains the installation program
5) Start the installer
For example, to launch the WebLogic Server Package installer on Windows 32-bit platforms, enter:
wls1036_win32.exe -mode=silent -silent_xml=path_to_silent.xml
(Here, path_to_silent.xml is the full path of the silent.xml file.)
An Oracle Installer window is displayed, indicating that the files are being extracted. No other prompt or text is displayed.

Continued…
Starting .bin Installation Programs in Silent Mode
1. Log in to the target UNIX system.
2. Create a silent.xml file that defines the configuration settings
4. Launch the installation program by entering the following commands:
./file_name.bin -mode=silent -silent_xml=path_to_silent.xml
In this command, file_name.bin is the name of the installation file and path_to_silent.xml is the full path of the silent.xml file.

Continued..
Starting .jar installation programs in Silent Mode
1.Log in to the target system.
2. Create a silent.xml file that defines the configuration settings.
3. Add the directory of the appropriate JDK to the PATH variable definition on the target system. For example, on UNIX or Linux
systems, add the bin directory to the beginning of the PATH variable:
4. Go to the directory that contains the installation file.
5. Launch the installation by entering the following command:
java -jar file_name.jar -mode=silent -silent_xml=path_to_silent.xml
In this command, file_name.jar is the name of the installation file and path_to_silent.xml is the full path to the silent.xml file.
An Installer window is displayed, indicating that the files are being extracted.

Exit Codes for Silent Mode Installation
When run in silent mode, the installation program generates exit codes that indicate the success or failure of the installation.
Exit Code Description
0 Installation completed successfully
-1 Installation failed due to a fatal error
1 Installation failed due to an internal XML parsing error
If we launch the silent-mode installation process from a script, we can choose to have these exit codes displayed on the console.
