we have 4 managed server nodes like
i am trying to created from server1 as just right click and click managed partitions option and then create new partition.
And give the name of partition name like test and it successfully created in server1 but it could not reflected in other three nodes.
EM should be targeted to AdminServer only... not the the managed servers...
Go to weblogic console, on deployments look for "em", go to targets and click on change target... Only AdminServer must be selected...
There's a good chance you'll have to recreate your domain, as it's looking like it was not properly configured as per Enterprise Deployment Guide...
