IBM's WebSphere Application Server (WAS 5.0 and 5.1) offers three products for application developers to choose from, each providing a different set of functionality:

  • WebSphere Application Server - Express
  • WebSphere Application Server - Base
  • WebSphere Application Server - Network Deployment

Typically, application developers who manage applications on multiple servers under one instance use WAS Network Deployment because it provides the interface to manage applications on multiple servers. But this article describes how to use the Base product to do the same thing.

The initial WAS Base Administrative Console allows application developers to manage the applications on the default server for an instance (i.e., the server that was created when the instance was created), but they cannot manage applications on additional servers for that instance. However, it is possible to configure the WebSphere Administrative Console so that each server has its own Administrative Console. This allows application developers to manage their applications on non-default servers (i.e., servers that were not created when the instance was created). To implement this configuration, follow these instructions:

1. Find the port for the non-default server to use for its WebSphere Administrative Console:

  1. Open a system command prompt and change to the was_install_root/bin directory.
  2. Run the dspwasinst command for the non-default server that you want to manage. The syntax of this command is
    dspwasinst –instance instancename –server servername
  3. In the results returned, find where the Web Container transports are listed. If the instance does not have security enabled, select one of the non-SSL ports to use as the WebSphere Administrative Console port. If security is enabled, choose an SSL port instead.

2. Assign the ports found in step 1 to the virtual host table:

  1. Go to the WebSphere Administrative Console for the default server.
  2. On the left sidebar, expand Environment and click on Virtual Hosts.
  3. In the virtual hosts table, click on admin_host.
  4. In the admin_host properties, click on Host Aliases.
  5. Under host aliases, click New to add the new port.
  6. Under host name, type the name of the host where the WebSphere Administrative Console will be located. Or, to include all hosts, type "*". Under the port field, enter the port that was found in step 1. Then, click OK.

Repeat steps 1 and 2 for each non-default server that contains applications to be managed through the WebSphere Administrative Console.

3. Deploy the WebSphere Administrative Console application on the server(s):

  1. Go to the WebSphere Administrative Console for the default server.
  2. On the left sidebar, expand Applications and click on Enterprise Applications.
  3. Click on the adminconsole application to view its properties.
  4. On the properties screen, click on Map modules to application servers.
  5. On the Map modules to application servers screen, select all the servers that will use the WebSphere Administrative Console, including the default server. Use the Ctrl button to select multiple servers. Then, click the check box next to the adminconsole application and click OK.

4. The changes that were made in steps 2 and 3 need to be saved to the master configuration, so click on Save in the upper left corner. Then, the in Save to Master Configuration screen, click Save to save the changes.

5. Restart the non-default server where the WebSphere Administrative Console was added.

6. Open the WebSphere Administrative Console for the non-default server at http://hostname:admin_port/admin.

At this point, application developers will be able to manage their non-default server applications through the WebSphere Administrative Console.

  • SB Profound WP 5539More than ever, there is a demand for IT to deliver innovation. Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects. The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the company are not aligned with the current IT environment.

  • SB HelpSystems ROBOT Generic IBM announced the E1080 servers using the latest Power10 processor in September 2021. The most powerful processor from IBM to date, Power10 is designed to handle the demands of doing business in today’s high-tech atmosphere, including running cloud applications, supporting big data, and managing AI workloads. But what does Power10 mean for your data center? In this recorded webinar, IBMers Dan Sundt and Dylan Boday join IBM Power Champion Tom Huntington for a discussion on why Power10 technology is the right strategic investment if you run IBM i, AIX, or Linux. In this action-packed hour, Tom will share trends from the IBM i and AIX user communities while Dan and Dylan dive into the tech specs for key hardware, including:

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
