Use this page to view or change the settings of an application server instance. An application server is a server which provides services required to run enterprise applications.
To view this administrative console page, click Servers > Application servers > server_name.
On the Configuration tab, you can edit fields. On the Runtime tab, you can look at read-only information. The Runtime tab is available only when the server is running.
Specifies a logical name for the server. Server names must be unique within a node. However, for multiple nodes within a cluster, you may have different servers with the same server name as long as the server and node pair are unique. You cannot change the value that displays in this field.
For example, a server named server1 in a node named node1 in the same cluster with a server named server1 in a node named node2 is allowed. Configuring two servers named server1 in the same node is not allowed. WebSphere Application Server uses the server name for administrative actions, such as referencing the server in scripting.
On the z/OS platform, this name is sometimes referred to as the long name.
Data type | String |
Default | server1 |
Specifies the short name of the server and must be unique within a cell. This field only applies to the z/OS platform. The short name is also the default z/OS job name and identifies the server to the native facilities of the operating system, such as Workload Manager (WLM), Automatic Restart Manager, SAF (for example, RACF), and started task control.
This field is optional. If you do not specify a value for the short name field, the short name defaults to BBOSnnn, where nnn is the first free number in the cell that can be used to create a unique short name. For example, if default short names are already assigned to two other servers in the cell, the short name BBOS003 will be assigned to this server if you do not specify a short name when you create this server. After the application server is created, you can change this generated short name to a name that conforms to your naming conventions.
The default values for the servant and adjunct jobnames are this short name with either an S, for the servant, or an A, for the adjunct, appended. If you must use an 8-character server short name, the servant and adjunct jobnames become 9-character names. Therefore, you must update the start command arguments for the servant and the adjunct process definitions to use the new 8-character server short name. The topic "Converting a 7-character server short name to 8 characters" describes how to perform this update.
Specifies the generic short name of the server and must be unique within a cell. This field only applies to the z/OS platform. The generic short name for the server becomes either the cluster transition name, if you are creating an unclustered server, or the cluster short name, if you are creating a clustered server.
This field is optional. If you do not specify a value for the generic short name field, the generic short name defaults to BBOCnnn, where nnn is the first free number in the cell that can be used to create a unique generic short name. For example, if default generic short names are already assigned to three other servers in the cell, the generic short name BBOC004 is assigned to this server if you do not specify a generic short name when you create this server.
Enabling this option may reduce the startup time of an application server. This may include JVM settings such as disabling bytecode verification and reducing JIT compilation costs. Do not enable this setting on production servers.
Specifies that you want to use the JVM properties -Xverify and -Xquickstart on startup. Before selecting this option, add the -Xverify and -Xquickstart properties as generic arguments to the JVM configuration.
If you select this option, you must save the configuration and restart the server before this configuration change takes effect.
The default setting for this option is false, which indicates that the server will not be started in development mode. Setting this option to true specifies that the server will be started in development mode (with settings that will speed server startup time).
Data type | Boolean |
Default | false |
Select this field to start the server on multiple threads. This might shorten the startup time.
Specifies that you want the server components, services, and applications to start in parallel rather than sequentially.
The default setting for this option is true, which indicates that the server be started using multiple threads. Setting this option to false specifies that the server will not be started in using multiple threads (which may lengthen startup time).
Note that the order in which the applications start depends on the weights you assigned to them. Applications that have the same weight start in parallel.
To set an application's weight, in the administrative console, click Applications > Enterprise Applications > application_name, and then select the Starting weight option.
Data type | Integer |
Default | 1 |
Range | 0 - 2147483647 |
Select whether there is a single class loader to load all applications or a different class loader for each application.
Specifies whether the class loader should search in the parent class loader or in the application class loader first to load a class. The standard for Developer Kit class loaders and WebSphere Application Server class loaders is Parent first.
This field only applies if you set the Class loader policy field to single.
If you select Parent last, your application can override classes contained in the parent class loader, but this action can potentially result in ClassCastException or linkage errors if you have mixed use of overridden classes and non-overridden classes.
The native operating system's process ID for this server.
The process ID property is read only. The system automatically generates the value.
The name of the cell in which this server is running.
The Cell name property is read only.
The name of the node in which this server is running.
The Node name property is read only.
The run-time execution state for this server.
The State property is read only.
