编辑 $ORACLE_HOME / network / admin / listener.ora为

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /usr/lib/oracle/xe/app/oracle/product/10.2.0/server)
      (PROGRAM = extproc)
    )
    (SID_DESC =
    (GLOBAL_DBNAME = XE)
    (ORACLE_HOME = /usr/lib/oracle/xe/app/oracle/product/10.2.0/server)
    (SID_NAME = XE)
     )
