配置ORACLE 10G DATA GUARD,报错ORA-12505

原创 Linux操作系统 作者:anchen211 时间:2008-11-04 16:37:48 0 删除 编辑

主库alert.log如下:

Tue Nov  4 15:44:46 2008
Errors in file /u01/app/oracle/admin/logstat1/bdump/logstat1_arc0_6272.trc:
ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
PING[ARC0]: Heartbeat failed to connect to standby 'test2'. Error is 12505.

从库alert.log报错如下:

Tue Nov  4 23:46:08 2008
Errors in file /u01/app/oracle/admin/logstat1/bdump/logstat1_mrp0_16454.trc:
ORA-12505: TNS:listener does not currently know of SID given in connect descriptor

经检查发现主从的监听和TNSNAMES.ORA的配置均正确无误.

tnsping均能正确返回.

但在从库中测试连接报错.

SQL> conn sys/oracle@test2 as sysdba
ERROR:
ORA-12505: TNS:listener does not currently know of SID given in connect
descriptor


Warning: You are no longer connected to ORACLE.
SQL> exit

监听的状态信息:

怀疑是没有正确监听的原因,手动进行注册如下

[oracle@localhost admin]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 5 00:19:51 2008

Connected to:

SQL> ALTER SYSTEM REGISTER;

System altered.

SQL> exit
Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

[oracle@localhost admin]$ sqlplus sys/oracle@test2 as sysdba

ERROR:
ORA-12505: TNS:listener does not currently know of SID given in connect
descriptor


Enter user-name:
ERROR:

Enter user-name:

仍然没有效果.

最后修改监听器的配置

[oracle@localhost arch]$ vi /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (SID_NAME = logstat1)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
    )

  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.10.204 )(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

增加红色区域后重启监听,问题解决.

这说明还是动态服务器注册的问题.
