See Roadmap for Installing and Configuring the Installation Topology for a roadmap that describes steps to create this topology.

Element	Description and Links to Additional Documentation
APPHOST	Standard term in Oracle documentation for the machine that hosts the application tier.
WebLogic Domain	Logically related group of Java components. In this case, the Administration Server, Managed Servers, and other related software components. See What is an Oracle WebLogic Server Domain? in Understanding Oracle Fusion Middleware.
Administration Server	Domain central control entity. Maintains domain configuration objects and distributes configuration changes to Managed Servers. See What is the Administration Server in Understanding Oracle Fusion Middleware.
Cluster	A collection of multiple WebLogic Server instances running simultaneously and working together. See Understanding Managed Servers and Managed Server Clusters in Understanding Oracle Fusion Middleware.
Machine	Logical representation of the computer that hosts one or more WebLogic Server instances (servers). Machines are also the logical glue between Managed Servers and Node Manager; to start or stop a Managed Server with Node Manager, the Managed Server must be associated with a machine.
Managed Server	Host for your applications, application components, Web services, and their associated resources. See Understanding Managed Servers and Managed Server Clusters in Understanding Oracle Fusion Middleware.

Obtaining the Oracle WebLogic Server and Coherence Distribution

To download Oracle WebLogic Server and Coherence software for development or evaluation, go to the Software Downloads page.

Note:

As of Oracle WebLogic Server 14c (14.1.2.0.0), the WebLogic Server and Coherence examples are provided in a separate examples JAR file, fmw_14.1.2.0.0_wls_examples.jar, which you install in the same ORACLE_HOME as your WebLogic Server installation. For more information about obtaining and installing WebLogic Server see Installing the WebLogic Server Code Examples .

To obtain Oracle WebLogic Server and Coherence, follow these steps:

Download the generic installer fmw_14.1.2.0.0_wls_Disk1_1of1.zip.
(Optional) Download the WebLogic Server and Coherence examples installer fmw_14.1.2.0.0_wls_examples.jar.
Extract the contents onto your system.
The extracted files run the product installer and install the software onto your system (Installing the Oracle WebLogic Server and Coherence Software).

Verifying Digital Signature and Integrity of Installation Archive Files

Oracle digitally signs the installation archive files with Oracle certificates to ensure the integrity of the packages before you deploy them in your environments.

Use the Java utility jarsigner to verify the integrity of your installation archive files. You can verify the integrity of the installation archive files before you extract the installation files.

Quick Verification

To quickly verify the installation archive files, use the jarsigner command with the -verify option:

Go to the directory where you have downloaded the installation archive files.
Run this command to check your installation archive file:
```
jarsigner -verify installation_archive_file
        
```
For example, to check the Oracle Fusion Middleware Infrastructure archive:
```
jarsigner -verify fmw_14.1.2.0.0_infrastructure.jar
```
```
jar verified.
```

Detailed Certificate Information

If you want detailed certificate information, then use the -verbose:summary and -certs along with the -verify option.

Go to the directory where you have downloaded the installation archive files.

Run this command to check your installation archive file:

jarsigner -verify -verbose:summary -certs installation_archive_file

For example, to check the Oracle Fusion Middleware Infrastructure image:

jarsigner -verify -verbose:summary -certs fmw_14.1.2.0.0_infrastructure.jar

The output is similar to the following:
