Weblogic Learning Part3

Node Manager

–>using node manager we can start/stop managed server from weblogic console.
–>Node manager is machine specific.
–>Shutdown Managed server

 -->grep the respective manged server process id
    -->ps -ef | grep -i <name of managed server>
 Note:The process id which is being followed by long list of processes, having a string -Dweblogic.Name ....
      that first id will be the process id of managed server and need to be killed
  -->kill -9 <processid>

—>Configuring Node Manger
———————–

1)Configure the unix machine
http://example.com:7001/console
Lock & Edit
Machines
New
Name : LinuxMachine1
Type: Unix
Type: Plain
Listen Address:localhost
Listen Port:5556

2)Add managed servers to the machine
3)Enrolling domain with nodemanager
–>It’s done with the help of wlst
[Direct Mode]
–>/u01/app/oracle/product/middleware/oracle_common/common/bin
–>./wlst.sh
–>wls:/offline> connect(‘weblogic’, ‘Oracle123’, ‘t3://example.com:7001’)
–>wls:/iam_domain1/serverConfig/> exit()
[interactive mode]
–>./wlst.sh
–>wls:/offline> connect()

                      Steps to enroll domain
                      ---------------------

wls:/iam_domain1/serverConfig/> nmEnroll(‘/u01/app/oracle/product/middleware/user_projects/domains/iam_domain1’, ‘/u01/app/oracle/product/middleware/user_projects/domains/iam_domain1/nodemanager’)
wls:/iam_domain1/serverConfig/>exit()

*Editing NodeManager.properties

cd $DOMAIN_HOME/nodemanager
vi nodemanager.properties
–>SecureListener=false

*Starting Node Manager

cd $DOMAIN_HOME/bin
./startNodeManager.sh

–>Note: go to ==>weblogic console>>Summary of Machines>>Linux Machine1>>Monitoring>>Node Manager Status
and make sure it’s Reachable.

–>Types of Node Manager: 1)Java Based : SSL,Plain
2)Shell Based : SSH,RSH

–>MSI Mode: Managed Server Indepenence Mode
