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/

arcch/
arch/

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
