Proxy server configuration

You can modify an existing proxy server to perform advanced routing options, such as routing requests to a non-WebSphere® Application Server cell, and to perform caching. The options to configure the proxy server from this panel are under Proxy server properties.

To view this administrative console page, click Servers > Server Types > WebSphere proxy servers > proxy_server_name

Name

Indicates a logical name for the proxy server. Proxy server names must be unique within a node.

[z/OS]

Short name

Specifies the short name for this cluster. This field only appears if you are running on z/OS®.

The short name is used as the WLM APPLENV name for all proxy servers that are part of this cluster.

If you specify a short name for a cluster member, the name:
  • Must be one to eight characters in length
  • Must contain only uppercase alphanumeric characters
  • Cannot start with a number
  • Must be unique in the cell

If you do not specify a short name, the system assigns a default short name that is automatically unique within the cell. You can change the generated short name to conform with your naming conventions.

Run in development mode

Enabling this option can reduce the startup time of a proxy server. This time can include Java™ Virtual Machine (JVM) settings, such as disabling bytecode verification and reducing just-in-time (JIT) compilation costs. Do not enable this setting on production servers.

Specify this option if you want to use the -Xverify and -Xquickstart JVM settings on startup. After selecting this option, save the configuration and restart the proxy server to activate development mode.

The default setting for this option is false, which indicates that the proxy server is not started in development mode. Setting this option to true specifies that the proxy server is started in development mode with settings that speed server startup time.

Information Value
Data type Boolean
Default false

Parallel start

Select this field to start the proxy server on multiple threads. This option might shorten the startup time.

Specify this option if you want the proxy server components, services, and applications to start in parallel, rather than sequentially.

The default setting for this option is true, which indicates that the proxy server is started using multiple threads. Setting this option to false specifies that the server does not start using multiple threads which might lengthen startup time.

The order in which the applications start depends on the weights that you assigned to each of them. Applications that have the same weight are started in parallel. You set the weight of an application with the Starting weight option on the Applications > Application Types > WebSphere enterprise applications > application_name page of the administrative console.

Default true

Start components as needed

Select this check box if you want the server components started as they are needed by an application that is running on this server.

When this check box is selected, server components are dynamically started as they are needed. When this check box is not selected, all of the server components are started during the server startup process. Therefore, selecting this option can improve startup time, and reduce the memory footprint of the server, because fewer components are started during the startup process.

Starting components as they are needed is most effective if all of the applications, that are deployed on the server, are of the same type. For example, using this option works better if all of your applications are web applications that use servlets, and JavaServer Pages (JSP). This option works less effectively if your applications use servlets, JavaServer Pages files and Enterprise JavaBeans™ (EJB).

Current Security Level

The current overall security level of the proxy server.

The overall security level is determined by evaluating the security settings. The possible values for Current Security Level are High, Medium, Low, and Not applicable. The overall security level is equal to the security level of the setting that is considered the least secure. For example, to have an overall security level of High, all settings must be configured to the values associated with a HIGH level of security. If any of the settings are configured with a less secure value, the overall security level is the value of that setting.

[z/OS]

Run in 64-bit mode

Enabling this option dedicates more storage for the proxy server than running in 31-bit mode.

Important: By default, newly configured servers run in 64-bit mode. You should not convert your new servers to run in 31-bit mode because support for 31-bit mode is deprecated. Instead, if you have any servers that are running in 31-bit mode, such as servers that you migrated from a previous release of the product, you should consider reconfiguring them to run in 64-bit mode.

Specify this option if you want to switch to 64-bit mode. After selecting this option, save the configuration and restart the proxy server to activate 64-bit mode.

The default setting for this option is false, which indicates that the proxy server is not started in 64-bit mode. Setting this option to true specifies that the proxy server is started in 64-bit mode with settings that speed server startup time.
