12/02/2017 17:08:55
Broker Configuration:       "dg_config"
      Protection Mode:            Maximum Availability
      Fast-Start Failover (FSFO): Disabled, flags=0x0, version=0
      Primary Database:           orcl (0x01010000)

2.查看broker是否正常

DGMGRL> show configuration;

Configuration - dg_config

  Protection Mode: MaxAvailability
  Members:
  orcl   - Primary database
    orcldg - Physical standby database 

Fast-Start Failover: DISABLED

Configuration Status:
SUCCESS   (status updated 57 seconds ago)       --正常可用。
因为设置了两个broker文件，所以损坏了一个文件没所谓。

二、处理过程

1.停掉dmon进程

SQL> alter system set dg_broker_start=false;
System altered.

2.复制配置文件

    $asmcmd -p
lsASMCMD [+] > 
DATADG/
ASMCMD [+] > cd datadg
ASMCMD [+datadg] > ls
ASM/
ORCL/
arcch/
arch/
orapwasm
ASMCMD [+datadg] > cd orcl
ASMCMD [+datadg/orcl] > ls
ARCHIVELOG/
CONTROLFILE/
DATAFILE/
DATAGUARDCONFIG/
ONLINELOG/
PARAMETERFILE/
TEMPFILE/
dr1.dat
ASMCMD [+datadg/orcl] > cp dr1.dat dr2.dat

3.启动dmon

SQL> alter system set dg_broker_start=true;

System altered.
SQL> !ps -ef|grep dmon
oracle   31088     1  0 17:40 ?        00:00:00 ora_dmon_orcl
oracle   31120 25505  0 17:40 pts/0    00:00:00 /bin/bash -c ps -ef|grep dmon
oracle   31122 31120  0 17:40 pts/0    00:00:00 grep dmon

SQL>

4.查看broker日志
