看出错误提示“无法获取文件状态”，在STANDBY 中没看到/opt/app/oracle/oradata/DB2/standby_redo04.log
日志文件 。


我的参数中配置为：
db_file_name_convert             string
DB1, DB2
可能在STANDBY 中已把 DB2 默认为文件 目录是：“/opt/app/oracle/oradata/DB2”。

在主库中查看并修改：


SQL> SHOW PARAMETER DB_FILE_NAME_CONVERT;

NAME                     TYPE
------------------------------------ ---------------------------------
VALUE
------------------------------
db_file_name_convert             string
DB1, DB2
SQL> ALTER SYSTEM SET DB_FILE_NAME_CONVERT='/opt/app/oracle/oradata/DB1','/opt/app/oracle/oradata/DB1' SCOPE=SPFILE;
System altered.

SQL> ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='/opt/app/oracle/oradata/DB1','/opt/app/oracle/oradata/DB1' SCOPE=SPFILE;                  
System altered.

SQL> SHOW PARAMETER LOG_FILE_NAME_CONVERT;

NAME                     TYPE
------------------------------------ ---------------------------------
VALUE
------------------------------
log_file_name_convert             string

SQL> ALTER SYSTEM SET DB_FILE_NAME_CONVERT='/opt/app/oracle/oradata/DB1','/opt/app/oracle/oradata/DB1' SCOPE=SPFILE;

System altered.

SQL> CREATE PFILE='/tmp/initDB1_stby.ora' from spfile;

File created.


ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=DB2 lgwr sync affirm VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=DB2';

SQL> ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=DB2 lgwr sync affirm VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=DB2';


并在STANDBY 库中修改pfile:

*.db_file_name_convert='DB1','DB2'
修改为：
*.db_file_name_convert='/opt/app/oracle/oradata/DB1','/opt/app/oracle/oradata/DB1'

*.log_file_name_convert='DB1','DB2'
修改为：
*.log_file_name_convert='/opt/app/oracle/oradata/DB1','/opt/app/oracle/oradata/DB1'


完成后的测试：

1.查看 redo 文件 已过来了。




2.在主库中测试插入：
SQL> insert into test values(11) ;

1 row created.

SQL> commit;

Commit complete.

SQL> alter system switch logfile;

System altered.


3.在STANDBY 中查看：
SQL> alter database recover managed standby database disconnect from session;

Database altered.

SQL> select * from test;

5.查看动态表：

    1.
    select * from v$dataguard_stats;

        NAME    VALUE    UNIT    TIME_COMPUTED    DATUM_TIME
    1        +00 00:00:00    day(2) to second(0) interval    08/01/2013 11:47:57    08/01/2013 11:47:55
    2    apply lag    +00 00:15:15    day(2) to second(0) interval    08/01/2013 11:47:57    08/01/2013 11:47:55
    3    apply finish time    +00 00:00:07.000    day(2) to second(3) interval    08/01/2013 11:47:57    
    4    estimated startup time    118    second    08/01/2013 11:47:57    


    2.查看日志传输情况
    select sequence#,first_time,next_time from v$archived_log;

    ......

    SEQUENCE# FIRST_TIME           NEXT_TIME
