为了更简单的管理data guard可以配置data guard broker来进行管理,配置broker过程如下:

[oracle@oracle11g ~]$ dgmgrl xxx/xxxxx@xxx
DGMGRL for Linux: Version 10.2.0.5.0 - Production

Copyright (c) 2000, 2005, Oracle. All rights reserved.

Welcome to DGMGRL, type "help" for information.
Connected.
DGMGRL> help

The following commands are available:

add            Add a standby database to the broker configuration
connect        Connect to an Oracle instance
create         Create a broker configuration
disable        Disable a configuration, a database, or Fast-Start Failover
edit           Edit a configuration, database, or instance
enable         Enable a configuration, a database, or Fast-Start Failover
exit           Exit the program
failover       Change a standby database to be the primary database
help           Display description and syntax for a command
quit           Exit the program
reinstate      Change a disabled database into a viable standby database
rem            Comment to be ignored by DGMGRL
remove         Remove a configuration, database, or instance
show           Display information about a configuration, database, or instance
shutdown       Shutdown a currently running Oracle instance
start          Start Fast-Start Failover observer
startup        Start an Oracle database instance
stop           Stop Fast-Start Failover observer
switchover     Switch roles between the primary database and a standby database

Use "help " to see syntax for individual commands

DGMGRL> show configuration
Error: ORA-16532: Data Guard broker configuration does not exist

Configuration details cannot be determined by DGMGRL
DGMGRL> help create

Create a broker configuration

Syntax:

  CREATE CONFIGURATION  AS
    PRIMARY DATABASE IS 
    CONNECT IDENTIFIER IS ;

创建broker配置文件

DGMGRL> create configuration 'broker_dg' as primary database is test connect identifier is test;
Configuration "broker_dg" created with primary database "test"
DGMGRL> show configuration

Configuration
  Name:                broker_dg
  Enabled:             NO
  Protection Mode:     MaxPerformance
  Fast-Start Failover: DISABLED
  Databases:
    test - Primary database

Current status for "broker_dg":
DISABLED

DGMGRL> help show configuration

Display information about a configuration, database, or instance

Syntax:

  SHOW CONFIGURATION;

  SHOW DATABASE [VERBOSE]  [];

  SHOW INSTANCE [VERBOSE]  []
    [ON DATABASE ];

DGMGRL> help add

Add a standby database to the broker configuration

Syntax:

  ADD DATABASE  AS
    CONNECT IDENTIFIER IS 
    MAINTAINED AS {PHYSICAL|LOGICAL};

向配置文件添加备库(物理备库test_dg)

DGMGRL> add database test_dg as connect identifier is test_dg maintained as physical;
Database "test_dg" added
DGMGRL> show configuration

Configuration
  Name:                broker_dg
  Enabled:             NO
  Protection Mode:     MaxPerformance

  Databases:
    test    - Primary database
    test_dg - Physical standby database

Current status for "broker_dg":
DISABLED

启用broker配置

DGMGRL> enable configuration
Enabled.

显示broker配置信息,显示如下错误信息:

DGMGRL> show configuration

显然是物理备库test_dg出了故障,检查备库的drctest_dg.log该日志文件在oracle10g中存储bdump文件中:

这里显示
'ArchiveLagTarget' has inconsistent values:METADATA='0', SPFILE='', DATABASE='0'
这说明archive_lag_target参数spfile文件的值与database,metadata的值不相同(它们都为0)。

'LogArchiveMaxProcesses' has inconsistent values:METADATA='2', SPFILE='', DATABASE='2' 这说明log_archive_max_processes参数spfile文件的值与database,metadata的值不相同(它们都为2)。

'LogArchiveMinSucceedDest' has inconsistent values:METADATA='1', SPFILE='', DATABASE='1' 这说明log_archive_min_succeed_dest参数spfile文件的值与database,metadata的值不相同(它们都为1)。

'LogArchiveTrace' has inconsistent values:METADATA='0', SPFILE='(missing)', DATABASE='0' 这说明log_archive_trace参数spfile文件的值与database,metadata的值不相同(它们都为0)。

'LogArchiveFormat' with sid='test_dg'
DG 2015-08-04-17:07:59 0 2 0 RSM Warning: Property 'LogArchiveFormat' has inconsistent values:METADATA='%t_%s_%r.dbf', SPFILE='(missing)', DATABASE='%t_%s_%r.dbf' 这说明log_archive_format参数spfile文件的值与database,metadata的值不相同(它们都为'%t_%s_%r.dbf')。

对以上不一致参数进行修改
