12c broker 配置文件损坏处理

一、问题描述
1.查看broker日志发现报错

tail -f drcorcl.log >> Starting Data Guard Broker bootstrap << Broker Configuration File Locations: dg_broker_config_file1 = "+DATADG/orcl/dr1.dat" dg_broker_config_file2 = "+DATADG/orcl/dr2.dat" 2017-12-02 17:08:50.847 DMON: Attach state object 2017-12-02 17:08:50.941 DMON: cannot open configuration file "+DATADG/orcl/dr2.dat", retrying 2017-12-02 17:08:51.952 DMON: cannot open configuration file "+DATADG/orcl/dr2.dat" 2017-12-02 17:08:51.954 ORA-17503: ksfdopn:2 Failed to open file +DATADG/orcl/dr2.dat 2017-12-02 17:08:51.954 ORA-15173: entry 'dr2.dat' does not exist in directory 'orcl' 2017-12-02 17:08:51.954 DMON: Error opening "+DATADG/orcl/dr2.dat", error = ORA-16572 2017-12-02 17:08:51.954 DMON: Establishing "+DATADG/orcl/dr1.dat" as the more current file 2017-12-02 17:08:51.958 DMON: rfafoGetLocks reinitializing dubious PMYSHUT lock value block contents: sts=0, flags=0x0, spare1=0x0, spare2=0x0, cksm=0x0, rndm=0x0 2017-12-02 17:08:51.958 DMON: Broker state reconciled, version = 0, state = 00000000 2017-12-02 17:08:51.958 DMON: Broker State Initialized 2017-12-02 17:08:51.958 Version = 1 2017-12-02 17:08:51.958 State = 00000000 2017-12-02 17:08:51.958 DMON: Entered rfm_get_chief_lock() for CTL_BOOTSTRAP, reason 2 2017-12-02 17:08:51.959 7fffffff 0 DMON: Entered rfm_get_chief_lock() for CTL_BOOTSTRAP, reason 0 2017-12-02 17:08:55.971 7fffffff 0 DMON: start task execution: broker initialization 2017-12-02 17:08:55.971 DMON: Boot configuration (0.0.0), loading from "+DATADG/orcl/dr1.dat" 2017-12-02 17:08:55.979 DMON Registering service orcl_DGB with listener(s) 2017-12-02 17:08:55.980 DMON: Executing SQL [ALTER SYSTEM REGISTER] 2017-12-02 17:08:55.980 SQL [ALTER SYSTEM REGISTER] Executed successfully 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

 <roidb01:+ASM:/home/grid>$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
