客户端连接服务器报ORA-285472010-01-07 14:13:07

分类： Oracle

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。

状况如下：

C:\>sqlplus "sys/oracle@vm9i as sysdba"

SQL*Plus: Release 10.2.0.1.0 - Production on 星期四 1月 7 13:41:20 2010

ERROR:
ORA-28547: 连接服务器失败, 可能是 Oracle Net 管理错误

请输入用户名:
ERROR:
ORA-01017: 用户名/口令无效; 登录被拒绝

SP2-0157: 在 3 次尝试之后无法连接到 ORACLE, 退出 SQL*Plus

而本地登录报ORA-03113错误。

[oracle@PENG admin]$ sqlplus system/oracle@vm9i

SQL*Plus: Release 9.2.0.4.0 - Production on Thu Jan 7 09:16:08 2010

本地操作系统认证登录却没问题

[oracle@PENG admin]$ sqlplus "sys/oracle@vm9i as sysdba"

[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。
