Installing and Updating License Files

The following sections explain how to acquire, install, and update your product licenses:

About BEA Product Licenses

BEA products use an XML-format license file called license.bea. This license file, stored in the BEA Home directory, is used for the BEA products installed in that directory. Your BEA software checks this file at run time to determine which product components you are authorized to use. In addition, for WebLogic Real Time 1.0, access to the JRockit Deterministic GC option requires an additional evaluation or production license key to replace the empty license.bea file in the JRockit /jre directory. For instructions on updating this license, see Updating Your BEA JRockit License for the Deterministic Garbage Collector.

Licenses are release specific. For example, to use WebLogic Server 9.1, you must have a 9.1 license file. To convert a pre-9.1 license.bea file to a WebLogic Server 9.1 license.bea file, see Upgrading Licenses from Previous Software Releases.

The types of license files that can be used as the license.bea file and the technical restrictions that they impose are described in the following table.

Table 6-1 WebLogic Real Time License File Types
License Type	Description
Development	Used in a development environment where a developer is preparing an application to run on top of your WebLogic Real Time software; a production license is required for deployment. Enables all component products provided in your product distribution. Enables you to run your software on a single machine, even if it is running multiple instances of WebLogic Server Permits client connections from a maximum of five IP addresses. IP addresses are tracked from the time the server is started. When you restart the server, the count is reset. Is installed in the BEA Home directory as `license.bea`. Is not tied to the IP address of a machine.
Production	Used in full-scale production environments. May restrict functionality to the software components that you have purchased. Enables you to run your software on a single machine, even if it is running multiple instances of WebLogic Server Permits client connections from an unlimited number of IP addresses. Must be purchased separately. For information about purchasing a production license, contact your sales representative or visit the BEA corporate Web site at `http://www.bea.com`. Is tied to the IP address of the machine. A production license can be used only on a machine with the same IP address that is specified in the license file.

When you install your software, a non-expiring development license file (license.bea) is installed on your system. By default, your software uses the development license installed with the product so that you can start using it immediately. Subsequently, when you install additional BEA products that include a license.bea file, the installation program automatically adds the new product licenses to the license.bea file.

Updating Your WebLogic Real Time Product License

When you install WebLogic Real Time, the installation program generates a development license.bea file for use with the software and installs it in the BEA Home directory. If you are installing your software in an existing BEA Home, the installation program automatically adds the development license included with your product distribution to the existing license.bea file.

In some cases, however, you must update the license.bea file separately, independent of the installation process. For example, you must update your license file if at least one of the following is true:

You purchase a product for production use and you receive a production license to replace your development license.
You want to upgrade production systems to a new release of the software. After installing the current release of the software, you must upgrade your license to the current version. To do so, see Upgrading Licenses from Previous Software Releases.
You purchase a new release of a product you are already using in production and you want to use both the old and the new releases in production on the same system. For example, you are currently using WebLogic Server 8.1, you purchase WebLogic Server 9.1, and you want to use both releases on the same system.
You purchase additional WebLogic Real Time software with production licenses, and you want to add the production licenses for the new software to the production licenses for software already in production use on your system.
You want to consolidate existing production licenses for different component products onto a single machine.
You want to transfer existing production licenses from one machine to another machine with a different IP address.

In each of these cases, you will receive a new license file from BEA, the contents of which must be included in the license.bea file in the target BEA Home directory. To facilitate the license update process, BEA provides an UpdateLicense utility that merges the new license into the existing license in the BEA Home directory, and deletes any expired or duplicate entries.

The UpdateLicense merge process is not intended to modify the license attributes for any component or feature in the license files being merged. For example:

If you merge a WebLogic Server 8.1 production license with a WebLogic Server 9.1 development license, the development and production rights associated with the different WebLogic Server license versions are retained. The merge process creates a single license file which can be used for both WebLogic Server 8.1 production and WebLogic Server 9.1 development. The merge process does not change the development and production rights associated with either the WebLogic Server 8.1 or WebLogic Server 9.1 entry. If you want to upgrade the WebLogic Server 8.1 production license to WebLogic Server 9.1, see Upgrading Licenses from Previous Software Releases.
If you merge a WebLogic Server 8.1 license for IP address A with a WebLogic Server 9.1 license for IP address B, the IP addresses for both WebLogic Server license versions are retained. The merge process creates a single license file that can be used to run WebLogic Server 8.1 on IP address A and WebLogic Server 9.1 on IP address B. The merge process does not change the IP address associated with either the WebLogic Server 8.1 or WebLogic Server 9.1 entry. If you want to change the IP address for a given license file, you must use the BEA eLicense system at http://elicense.bea.com.

Important Considerations for Updating Your license.bea File

When determining how to update your license.bea file, you should consider the following:

Updating license.bea Using the UpdateLicense Utility

Save the license update file that you received through e-mail, with a name other than license.bea, in the target BEA Home directory. For example, save the file as new_license.bea. Use this file as the license_update_file in step 4 of this procedure.

WARNING: Do not overwrite or change the name of the existing license.bea file.

Perform the step appropriate for your platform:

On a Windows system, open an MS-DOS command window and go to the target BEA Home directory.
On a Linux system, go to the target BEA Home directory.

If it is not already included, add the JDK to your PATH variable by entering the following commands:

On a Windows system:

set PATH=BEA_HOME\JDK\bin;%PATH%

On a Linux system:

PATH=BEA_HOME/JDK/bin:$PATH export PATH

In this command, JDK represents the directory that contains the JDK being used for this installation, for example, jdk150_04 or jrockit90_150_04.

Merge the license update file into your existing license by entering one of the following commands:

On a Windows system:

UpdateLicense license_update_file

On a Linux system:

sh UpdateLicense.sh license_update_file

license_update_file represents the name to which you saved the license update file in step 1.

Save a copy of your updated license.bea file in a safe place outside your BEA software and application installation directories.

Although no one else can use your license file, you should save a copy of it in a place that is protected from both malicious and innocent tampering.

Updating Your BEA JRockit License for the Deterministic Garbage Collector

For WebLogic Real Time 1.0, access to the BEA JRockit 5.0 Deterministic Garbage Collection option requires an additional evaluation or production license key to replace the empty license.bea file in the BEA_HOME/jrockit-realtime1.0_XXX/jre/ directory. To enable deterministic garbage collection, this key must be replaced with an evaluation or production Deterministic GC license.

These steps explain how to update the empty BEA JRockit license file with the evaluation Deterministic GC license key:

Download the evaluation JRockit Deterministic GC license from the WebLogic Real Time Product download page at http://commerce.bea.com/showproduct.jsp?family=WLRT&major=1.0&minor=0.
To install the evaluation JRockit Deterministic GC license, simply copy it to:

BEA_HOME/jrockit-realtime1.0_XXX/jre/

WARNING:

If you already have a JRockit Mission Control license, you should make a backup copy before overwriting it with the Deterministic GC license.

The name of the license should be license.bea, thus, the full path to the license should be:

BEA_HOME/jrockit-realtime1.0_XXX/jre/license.bea

To enable the Deterministic GC option, you can:

For WebLogic Server, start the server with the -Xgcprio:deterministic option in the startup script.
For standalone Java applications, enter the -Xgcprio:deterministic option from a Java command line.
Use Start BEA Home Tools Configuration Wizard to create a WebLogic domain with the Deterministic GC enabled.

Note:

Follow steps 2-4 when updating the BEA JRockit license with either a WebLogic Real Time 1.0 CD-ROM kit evaluation license or a WebLogic Real Time 1.0 production license obtained from BEA.

Upgrading Licenses from Previous Software Releases

The format of the license.bea file changes with each release of WebLogic Real Time software. To upgrade a license.bea file from a previous release to a license for the current release, complete the following steps:

Note:

You need a BEA eLicense account to log in to this Web site. If you do not have a BEA eLicense account, click the Register link on the Customer Support site to register for one.

In the left navigation area of the Web page, click Upgrade/Downgrade and follow the instructions on the page. If the license you want to upgrade is not listed, click the Add a Missing License link. The BEA Licensing team will research the missing license for you.

You will receive an upgraded license file through e-mail. To update the license.bea file on your system, see Updating license.bea Using the UpdateLicense Utility.

Installing Licenses for Use with Promotional CD Distributions

In some cases, BEA distributes software for promotional purposes on CD. Such CDs include installers that do not automatically generate a development license key. Instead, the CD folio directs you to a BEA Web site, where you can obtain a development license file after you supply a code from the CD folio. The license file you obtain allows you to begin using the software immediately, and entitles you to the same usage rights described for the development license in Table 6-1, WebLogic Real Time License File Types, on page 6-2.
