客户端版本是10.2.0.1.0 32位， 服务器是9.2.0.4.0 64位。客户端连接服务器报ORA-28547: 连接服务器失败, 可能是 Oracle Net 管理错误。

[oracle@PENG admin]$ tnsping vm9i
TNS Ping Utility for Linux: Version 9.2.0.4.0 - Production on 07-JAN-2010 09:19:38

Used parameter files:
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.222)(PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = dbtest) (INSTANCE_NAME = dbtest)))
OK (10 msec)
最后检查了一下监听程序的配置文件 发现多了 (PROGRAM = extproc)
[oracle@PENG admin]$ vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = dbtest)
(ORACLE_HOME = /u01/app/oracle)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.222)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
手工配置监听的时候，从上面COPY下来的 就后面的那个没去掉。去掉 (PROGRAM = extproc)
保存退出。
