Create and Configure Managed Servers in Oracle WebLogic Server

Before You Begin

This tutorial shows you how to create, configure, and start Oracle WebLogic Server Managed Servers.

Background

This tutorial is part of the Oracle WebLogic Server 12c series and assumes that you have completed this tutorial:

Install WebLogic Server and Create a Basic Domain

A WebLogic Server domain always has exactly one Administration Server. This special instance of WebLogic Server is responsible for the configuration of the entire domain. Other servers in the domain are called Managed Servers and they are typically the servers on which you run your applications. A domain may contain any number of Managed Servers.

This tutorial covers creating and configuring Oracle WebLogic Server Managed Servers by using the Oracle WebLogic Server Administration Console. It also shows you how to start Managed Servers from the command line using the domain start script.

What Do You Need?

An installation of Oracle WebLogic Server 12c. See http://www.oracle.com/technetwork/middleware/weblogic/downloads/index.html.
This tutorial uses an instance of WebLogic Server installed in /u01/app/fmw.
A properly configured Oracle WebLogic Server domain containing an Administration Server and the following settings:

Domain directory: /u01/domains/ExampleDomain
Administration Server Listen Address and Port Number: localhost:7001
Domain administrator credentials: The user name and password you specified when you created the domain.

Creating Managed Servers

To create Managed Servers in the domain:

If the Administration Server of the domain is not already running, start it.
- Open a terminal window and navigate to the domain directory:
- In the domain directory, enter:
- At the prompt, enter the credentials of the domain administrator.
- Examine the terminal output and wait for the Administration Server to reach the RUNNING state.
After the Administration Server is running, access the WebLogic Server Administration Console.

Open a web browser and enter the URL:

http://localhost:7001/console

On the Welcome screen, enter the user name and password that you specified when you created the domain, and then click Login.

In the left pane of the Console, under Domain Structure, expand Environment, and then select Servers.

On the Summary of Servers page, you can view all the servers defined in the domain.
To create Managed Servers, or change anything in the domain configuration, you must first lock the domain configuration (to prevent other accounts from making changes during your edit session) and enable an edit session.

In the Change Center, click Lock & Edit.
In the Servers table, click New.

Enter the required properties for a new server:

Server Name: server1
Server Listen Port: 7003

Click Finish.
The Console displays the message: Server created successfully.

Repeat step 5 to create server2, listen port 7005, and server3, listen port 7007.
In the Change Center, click Activate Changes.

The Console displays the message: All changes have been activated. No restarts are necessary.
The Administration Console updates the domain configuration with the new server configuration data.

Configuring Managed Servers

To configure Managed Servers:

On the Summary of Servers page, select server1.

The settings for server1 are displayed.
To modify the settings for server1, you must first lock the domain configuration and enable an edit session.

In the Change Center, click Lock & Edit.
Under Settings for server1, select Logging, and then General.
Change the rotation file size to 7500. This increases the size of the server log files before a new log file is created.
Click Save.

The Console displays the following message: Settings updated successfully.

Also increase the log file rotation size of server2 by performing the following steps:

Under Domain Structure, expand Environment, and then select Servers.
In the Servers table, select server2.
Under Settings for server2, select Logging, and then General.
Change the rotation file size to 7500.
Click Save.

In the Change Center, click Activate Changes.

The Console displays the message: All changes have been activated. No restarts are necessary.
The Administration Console updates the domain configuration with the new server configuration data.

Starting Managed Servers

To start Managed Servers:

Run the Managed Server start script.

Open a terminal window and navigate to the bin directory under your domain directory. In this tutorial, the domain directory is: /u01/domains/ExampleDomain
Enter: startManagedWebLogic.sh

This command takes two arguments: the name of the Managed Server that you want to start and the URL of the Administration Server
In this tutorial, the values for those arguments are: server1 and http://localhost:7001

$ cd /u01/domains/ExampleDomain/bin
$ ./startManagedWebLogic.sh server1 http://localhost:7001

At the prompt, enter the administrator user name and password.

NOTE

Wait for the following terminal output messages:

<Aug 23, 2018 9:57:34,722 AM EDT> <Notice> <WebLogicServer> <BEA-000360> <The server started in RUNNING mode.>
<Aug 23, 2018 9:57:34,817 AM EDT> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to RUNNING.>

Repeat steps 1 and 2 to start server2.
In the Administration Console:

If you need to log in again, do so.
Under Domain Structure, expand Environment, and then select Servers.
In the Servers table, examine server1 and server2. Both should show their state as RUNNING.
