The following sections provide information that you need to know before installing the BEA WebLogic SIP Server software:
The BEA installation program supports the following methods for installing the BEA WebLogic SIP Server software:
Graphical-mode installation is an interactive, GUI-based method for installing WebLogic SIP Server. It can be run on both Windows and UNIX systems. For installation procedures, see Installing WebLogic SIP Server Using Graphical-Mode Installation.
Note: | If you want to run graphical-mode installation, the console attached to the machine on which you 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 you attempt to start the installation program in graphical mode on a system that cannot support a graphical display, the installation program automatically starts console-mode installation. |
Console-mode installation is an interactive, text-based method for installing WebLogic SIP Server from the command line, on either a UNIX system or a Windows system. For instructions for using this method, see Installing WebLogic SIP Server Using Console-Mode Installation.
Silent-mode installation is a noninteractive method of installing WebLogic SIP Server that requires the use of an XML properties file for selecting installation options. You can run silent-mode installation in either of two ways: as part of a script or from the command line. Silent-mode installation is a way of setting installation configurations only once and then using those configurations to duplicate the installation on many machines. For instructions, see Installing WebLogic SIP Server Using Silent-Mode Installation.
WebLogic SIP Server is distributed on both the BEA Web site and CD-ROM.
You can download the WebLogic SIP Server software from the BEA Web site at
http://commerce.bea.com
.
If you purchased WebLogic SIP Server from your local sales representative, the installation program and documentation are included on the product CD-ROM.
The following sections specify the installation prerequisites for a WebLogic SIP Server installation:
The minimum system requirements for WebLogic SIP Server are given in the following table.
A configuration of hardware and operating system that is supported by WebLogic Platform is required. See
WebLogic SIP Server Supported Configurations.

The WebLogic Platform installation program requires a Java run-time environment (JRE) to run. A JRE is bundled in the Windows installation program and in some UNIX installation programs (those with filenames ending in
.bin ). Both the BEA WebLogic JRockit SDK (Windows and Linux only) and the Sun Java 2 SDK are installed on your system. You can specify the SDK to use with your domains when you create the domains with the Configuration Wizard.
|
The BEA installation program uses a temporary directory in which it extracts the files necessary to install WebLogic SIP Server on the target system. During the installation process, your temporary directory must contain sufficient space to accommodate the compressed Java run-time environment (JRE) bundled with the installation program and an uncompressed copy of the JRE that is expanded into the temporary directory. The extracted files are deleted from the temporary directory at the end of the installation process. As a general rule, installation programs require approximately 2.5 times the amount of temporary space that is ultimately required by the installed files.
By default, the installation program uses the following temporary directory:
Note: | If you do not have enough temporary space to run the installation program, you are prompted to specify an alternate directory or exit the installation program. |
To make sure that you have adequate temporary space, you may want to allocate an alternate directory for this purpose. To do so, follow the instructions provided in the following table.
When you use the Configuration Wizard to create user domains, you have the option to configure the Administration Server as a Windows service. When the Node Manager or a server is installed as a Windows service, it starts automatically each time you boot your Windows system. You must have Administrator privileges to install the Node Manager or a server as a Windows service.
For additional information, see Starting and Stopping Servers in the WebLogic Server 9.2 documentation set.
Secure sockets layer (SSL) encryption software is available with two levels of encryption: 56-bit and 128-bit. WebLogic SIP Server enables both levels by default.
During installation of WebLogic SIP Server, you need to specify locations for the following directories:
When you install WebLogic SIP Server, you are prompted to specify a BEA Home directory. This directory serves as a repository for common files that are used by multiple BEA products installed on the same machine. For this reason, the BEA Home directory can be considered a central support directory for the BEA products installed on your system.
The files in the BEA Home directory are essential to ensuring that BEA software operates correctly on your system. They perform the following types of functions:
The following illustration shows the structure of a sample BEA Home directory, created by the WebLogic SIP Server installation program.
This illustration depicts only the files and directories required in the BEA Home directory. If you choose the default product installation directory, however, you will see additional directories in the BEA Home directory, such as sipserver31
. Although the default location for the product installation directory is within the BEA Home directory, you can select a different location outside the BEA Home directory.
During installation of WebLogic SIP Server, you are prompted to choose an existing BEA Home directory or specify a path to create a new BEA Home directory. If you choose to create a new directory, the WebLogic SIP Server installation program automatically creates the directory for you.
Note: | For a BEA Home directory, you are allowed to install only one instance of each version of a BEA product that uses the BEA Home directory convention. For example, you can install only one instance of WebLogic SIP Server 3.1 in a BEA Home directory, but that BEA Home directory may also contain an earlier version of WebLogic SIP Server. |
The files and directories in the BEA Home directory are described in the following table.
Although it is possible to create more than one BEA Home directory, BEA recommends that you avoid doing so. In almost all situations, a single BEA Home directory is sufficient. There may be circumstances, however, in which you prefer to maintain separate development and production environments, with a separate product stack for each. With two directories, you can update your development environment (in a BEA Home directory) without modifying the production environment until you are ready to do so.
The product installation directory contains all the software components that you choose to install on your system, including program files and examples. You are prompted, during the initial installation of WebLogic SIP Server, to choose a product installation directory. If you accept the default, the WebLogic SIP Server software is installed in the following directory:
C:\bea\sipserver31
Here, C:\bea
is the BEA Home directory and sipserver31
is the product installation directory for the WebLogic Platform software. However, you can specify any name and location on your system for your product installation directory; there is no requirement that you name the directory sipserver31
or create it under the BEA Home directory.
The installation program installs the software components in a product installation directory represented by the WL_HOME
variable. If, on your initial installation, you choose to install individual components of WebLogic SIP Server and not the full complement of products, and later decide to install additional components (using the same BEA Home directory), you are not prompted, during the subsequent installations, to specify a product installation directory. The installation program detects the WL_HOME
directory and installs the additional components under in it.
A description of the WebLogic Platform directory structure is provided in Selecting Directories for the WebLogic SIP Server Installation.
If you launch the installation from the command line or from a script, you can specify the -log
option to generate a verbose installation log. The installation log stores messages about events that occur during the installation process, including informational, warning, error, and fatal messages. This type of file can be especially useful for silent installations.
Note: | You may see some warning messages in the installation log. However, unless a fatal error occurs, the installation program completes the installation successfully. The installation user interface indicates the success or failure of each installation attempt, and the installation log file includes an entry indicating that the installation was successful. |
To create a verbose log file during installation, include the -log=
full_path_to_log_file
option in the command line. For example:
platform
XXX
_win32.exe -log=C:\logs\platform_install.log
In this filename, XXX
represents the version number of the software you are installing.
The path must specify a file. You cannot create a folder simply by including a name for it in a pathname; your path should specify only existing folders. If your path includes a nonexistent folder when you execute the command, the installation program does not create the log file.
