Getting Node id, Cell ID, Server ID of Mbean in wsadmin

By -
Hey automation expert welcome to another interesting exploration on wsadmin basic commands that could build your Jython script much effectively. Let's jump into it.
Basic understanding of wsadmin objects
Here I've listed out what we need to consider as wsadmin objects which could help as build blocks for your Jython based automation scripts.
  • Node – an individual system, either physical or virtual
  • Node Manager – the process controlling the individual node and all servers in all cells, it executes the commands of the Deployment Manager
  • Profile – a WebSphere entity similar to a node concept wise
  • Application Server – a Java Virtual Machine (JVM) process
  • Application – a Java enterprise application it could be .ear file with some modules
  • Cluster – a group of Servers, all running the same applications
  • Cell – an administrative domain of one or more servers
  • Deployment Manager (DM) – the administration application for a cell

How do all these pieces work together? 

 “Multiple Nodes in a Cell run Servers that contain Applications. All pieces are controlled via the Deployment Manager”

How to retrieve Node ID in wsadmin?

This task is very much required for most of the create method executions. When you create servers, when you construct Cluster Member servers your script need Node id. Ofcourse if you wish to Sync the differe!!nt members of a node also requird the Node id.

wsadmin>AdminConfig.getid('/Node:DmgrNode05')
'DmgrNode05(cells/DmgrCell05/nodes/DmgrNode05|node.xml#Node_1)'

How to retrieve Cell Name in wsadmin?

wsadmin>CellName=AdminControl.getCell()

What is the command to Retrieving Cell ID in wsadmin?

 wsadmin>AdminConfig.getid('/Cell:'+CellName)
'DmgrCell05(cells/DmgrCell05|cell.xml#Cell_1)'

How can I retrieve the Servers list in wsadmin?

 wsadmin>AdminTask.listServers('[-serverType APPLICATION_SERVER]')
'server1(cells/DmgrCell05/nodes/AppSrvNode/servers/server1|server.xml)'

How to fetch the Server ID on wsadmin?

wsadmin>AdminConfig.getid('/Server:server1')
'server1(cells/DmgrCell05/nodes/AppSrvNode/servers/server1|server.xml#Server_1407376951191)'
wsadmin>

Different automation scripts requires the wsadmin provided MBean values. so that we can store in the Jython variables like list and strings we can use them further to enhance the automation logics.

Hoping this post helped you in doing simple command exections on your wsadmin prompt. Keep writing your comments and thoughts on this blog

Server Control from wsadmin The building blocks for this script are as follows: Get Node name  Get the Server name Get the server state Using the AdminControl stop/start/restart How to get Node Name in wsadmin using Jython? We can use the nodeName using AdminControl  with getNode method or completeObjectName querying. wsadmin>nodeName=AdminControl.getNode() wsadmin>print nodeName ubuntu-was8Node01 wsadmin>objn = AdminControl.completeObjectName('WebSphere:type=Server,*') wsadmin>print objn WebSphere:name=server1,process=server1,platform=proxy,node=ubuntu-was8Node01,j2eeType=J2EEServer,version=8.5.5.6,type=Server,mbeanIdentifier=cells/ubuntu-was8Node01Cell/nodes/ubuntu-was8Node01/servers/server1/server.xml#Server_1183121908656,cell=ubuntu-was8Node01Cell,spec=1.0,processType=UnManagedProcess wsadmin>print AdminControl.getAttribute(objn, 'nodeName') ubuntu-was8Node01 In the above interaction we have experimented in two options directl...

Jython Deployment automation in WebSphere

We can have different JEE applications to install on IBM WebSphere Application Server such as: Enterprise applications .ear files Web Applications .war files Business Application Utility/shared libraries .jar files You need to know what type of application you wish to deploy. Where to install it in the Cell. If it is an EJB application you need to provide the binding details as an initial parameter. All application-related functions are available with AdminApp object. For making the application changes permanent you need to save the AdminConfig. Web application deployment with Jython wsadmin Let's see the war file installation process AdminApp.install(ear, '[-BindJndiForEJBBusiness [[ejb_1.jar ejb1 ejb_1.jar,META-INF/ejb-jar.xml test.ejb1 jndi1 ]]]') # For Web application inside .ear files you need to provide virtual host name. These virtual host varies in the ND cell. AdminApp.install('fullpath/yourApp.ear', ['-MapWebModToVH', [[...

Hello automation with Jython enthuiastic Guys!! Welcome to this post. In this post we are going to explore more WebSphere cluster specific operations. Which are most important for doing automations with wsadmin scripting. Cluster State using Jython You can get the state of the cluster using AdminControl object method getAttribute will give that. The cluster state might be one of the three common important states websphere.cluster.running websphere.cluster.partial.start websphere.cluster.partial.stopped websphere.cluster.stopped Cluster object required to get the state of the cluster, AdminControl will gives us the state of the cluster getAttribute method will takes two argument cluster object and 'state' command. Cluster = AdminControl.completeObjectName('cell='+ cell +',type=Cluster,name='+ cluster +',*') state = AdminControl.getAttribute(Cluster, 'state') Start Cluster with Jython To start the member servers of a clust...
