High Availability with WebLogic Clusters - Oracle WebLogic Server 12c Advanced Administration - page 37

Getting ready
Make sure the Administration Server is up and Node Manager is running on all machines
in the domain.
If the cluster PROD_Cluster was created previously, delete it from the domain before
creating the new one:
1. Log in as a wls user to shell and start WLST:
[wls@prod01]$ $WL_HOME/common/bin/wlst.sh
2. Connect to the Administration Server using wlsadmin as the user, <pwd> as the
password and t3://prod01.domain.local:7001 as the server URL:
wls:/offline> connect("wlsadmin","<pwd>","t3://prod01.domain.
local:7001")
3. Run the following WLST commands to delete the original PROD_Cluster cluster and
the Managed Server instances:
edit()
startEdit()
editService.getConfigurationManager().removeReferencesToBean(getMB
ean('/Clusters/PROD_Cluster'))
cd('/')
cmo.destroyCluster(getMBean('/Clusters/PROD_Cluster'))
cd('/Servers/PROD_Server01')
cmo.setCluster(None)
cmo.setMachine(None)
editService.getConfigurationManager().removeReferencesToBean(getMB
ean('/Servers/PROD_Server01'))
cd('/')
cmo.destroyServer(getMBean('/Servers/PROD_Server01'))
cd('/Servers/PROD_Server02')
cmo.setCluster(None)
cmo.setMachine(None)
