myeclipse连接oracle错误

ora-12505 
1.重新启动监听程序
2.listener.ora中增加红色部分
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = E:\oracle\product\10.2.0\db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = E:\oracle\product\10.2.0\db_1)
(SID_NAME = orcl)
)
  )
通过sql*plus连接数据库
执行select INSTANCE_NAME from v$instance;
把SID_NAME改成这个结果。

ora-00604  eclipse下的eclipse.ini中，Duser.language=en改成Duser.language=zh
