WLST exceptions

Property “Name” of Server with original name “_sample” is invalid. The property value is duplicated

Actually means that when you read the domain, the existing server in config.xml had not been started with AdminServer running (which creates the server directory for the domain).

Similarly, you must give a JDBC System Resource a name explicitly:

jdbcSR=create(dsName, 'JDBCSystemResource')
jdbcSR.setName(dsName)

WLSTException: 'Error occured while performing deploy : Error deploying the applicationError occured while performing deploy : Unexpected Error.Error occured while performing deploy : Could not find Targets that match mdm-weblogic-8089 in null Use dumpStack() to view the full stacktrace Use dumpStack() to view the full stacktrace'

The “null” is the list of available servers to deploy to. Can look at {domain}\config\config.xml and see that new server did get written, but deploy is not viewing that server as an acceptable target to deploy to.

This is because the AdminServer was (already) running. The offline script updated the config.xml, but the already running AdminServer did not pick up the change, so it did not see any target it could deploy to.
