Node agent server settings

Use this page to view information about and to configure a node agent. A node agent coordinates administrative requests and event notifications among servers on a machine. A node agent is the running server that represents a node in a WAS Network Deployment environment. To view this console page, click System administration > Node agents > node_agent.

A node agent must be started on each node for the deployment manager node to collect and control servers configured on that node. If we use configuration synchronization support, a node agent coordinates with the deployment manager server to synchronize the configuration data of the node with the master copy that the deployment manager manages.

We must initially start a node agent outside the console. For information on how to initially start a node agent, see the addNode command and the startNode command.

The Runtime tab displays only when a node agent runs.


Name

Logical name for the node agent server.

Information Value
Data type String


Node

Name of the node for the node agent server.

Information Value
Data type String


(zos) Short name

Short name of the node agent server.

The server short name must be unique within a cell. The short name identifies the server to the native facilities of the operating system, such as Workload Manager (WLM), Automatic Restart Manager, System Authorization Facility (SAF) (for example, Resource Access Control Facility (RACF )), started task control, and others.

The name can be 1-8 alphanumeric or national language characters and cannot start with a numeric.

The system assigns a cell-unique, default short name.


(zos) Unique ID

Unique ID of this node agent server.

The unique ID property is read only. The system automatically generates the value.


(zos) Run in 64 bit JVM mode

Whether to run the node agent in 64-bit addressing mode to obtain more than the virtual memory that is available to the node agent when the node agent runs in 31-bit addressing mode, which is 2 gigabytes (GB).

Deprecated feature: You should eventually convert all of your servers to run in 64-bit addressing mode because support for running servers in 31-bit addressing mode is deprecated.depfeat

Information Value
Default true (checked)


Start components as needed

Select this property if you want the server components started as they are needed for applications that run on this server.

When this property is not selected, all of the server components are started during the startup process. Therefore, selecting this property usually results in improved startup time because fewer components are started during the startup process.

Avoid trouble: If we are running other WebSphere products on top of the this product, make sure that those other products support this functionality before you select this property.gotcha


Process ID

Specifies a string identifying the process.

Information Value
Data type String


Cell name

Name of the cell for the node agent server.

Information Value
Data type String
Default hostNetwork


Node name

Name of the node for the node agent server.

Information Value
Data type String


State

Indicates whether the node agent server is started or stopped.

Information Value
Data type String
Default Started


Current heap size

Indicates the current heap size that the server JVM uses, in megabytes.


Maximum heap size

Indicates the maximum heap size that the server JVM can use, in megabytes.
