Define groups of nodes to simplify large environment configurations.
Node groups allow you to submit jobs to multiple nodes.
Before you begin
Create a job manager and register one or more nodes in
a flexible management environment. Verify that the job manager process
is running.
About this task
여러 배치 관리자 간의 관리 조치를 조정하고,
연합되지 않은 여러 개의 애플리케이션 서버를 비동기적으로 관리하며,
작업 관리자가 포함된 관리 프로파일에서 서버를 시작하는 작업을 제출할
수 있습니다. 작업 관리자를 사용하여 작업을 실행하려면 애플리케이션 서버
및 배치 관리자 노드를 작업 관리자의 관리 노드로 등록하십시오.
Node
groups can be used to improve your system administration, including
easy management of branch office systems and server farms. For example,
a business has 1000 global store locations, and each location has
three application servers. Each store location is connected to the
business headquarters data center. The business manages all systems
and runs jobs from the business headquarters. In this scenario, the
business can easily manage the branch offices by creating one node
group per continent.
Procedure
- Launch the wsadmin tool.
Navigate to the
app_server_root/bin directory
and run the following command to launch the wsadmin tool and connect
to the job manager process:
wsadmin -profileName myJobManager -lang jython
- Create a node group.
Use the
createManagedNodeGroup command
to create a new node group in your flexible management configuration:
AdminTask.createManagedNodeGroup('-groupName European_Branch_Offices
-description "Management group for all European branch offices"')
- Add nodes to the node group.
Use the
addMemberToManagedNodeGroup command
to add nodes to the new group. Each node can belong to one or more
groups. The following example commands add the
Hursley_office,
Berlin_office,
Warsaw_office,
and
Paris_office nodes to the
European_Branch_Offices node
group:
AdminTask.addMemberToManagedNodeGroup('-groupName European_Branch_Offices -managedNodeNameList
"[Hursley_Node01][Berlin_Node01][Warsaw_Node01][Paris_Node01]"')
- Optional: Verify that the system added the
nodes to the node group.
Use the
getManagedNodeGroupMembers command
to display the nodes for the node group of interest, as the following
example displays:
AdminTask.getManagedNodeGroupMembers('-groupName European_Branch_Offices')
The command returns a list of node names that are registered
with the node group of interest, as the following sample output displays:
"[Hursley_Node01][Berlin_Node01][Warsaw_Node01][Paris_Node01]"
Results
A node group with node group members exists in your flexible
management configuration.
What to do next
Use the job manager to submit, monitor, and manage jobs
for your node groups.
