一、问题描述
1. 查看 broker 日志发现报错
| tail -f drcorcl.log | |

| 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
