adpreclone on dbTier failled RC-40003

@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=server

Hi,
on R12.2 and DB 11.2.0.4 on AIX

running :

perl adpreclone.pl dbTier
adpreclon failed with
RC-40003: Fatal: Unable to connect to database as APPS schema
And in log file
JDBC URL: jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=server.us.oracle.com)(PORT=xxx))(CONNECT_DATA=(SERVICE_NAME=vision.us.oracle.com)))
WARNING:     Exception occurred: java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection
    Connection could not be obtained; returning null
But I can connect in sqlplus :

sqlplus apps/***@vision
It seems that it's a jdbc problem because domain  name (us.oracle.com) in connection string is not correct.
