Data Guard Broker配置篇
一、在配置好的DG上修改Listener文件，增加GLOBAL_DBNAME.
注意这里的GLOBAL_DBNAME参数格式：<db_unique_name>_DGMGRL.<db_domain> 的连接。
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.233.150)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcm)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcm)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl_st_DGMGRL)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcm)
)
)
ADR_BASE_LISTENER = /u01/app/oracle
二、重启监听，会发信啊之前配置的orcl_st_DGMGRL也注册进来了

三、进入后查看配置信息
DGMGRL> show configuration
Configuration - OrclBroker
Protection Mode: MaxAvailability
Databases:
orcl_pd - Primary database
orcl_st - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
1.查看主库信息
DGMGRL> show database verbose 'orcl_pd';
Database - orcl_pd
Role: PRIMARY
Intended State: TRANSPORT-ON
Instance(s):
orcl
Properties:
DGConnectIdentifier = 'orcl_pd'
ObserverConnectIdentifier = ''
LogXptMode = 'SYNC'
DelayMins = '0'
Binding = 'optional'
MaxFailure = '0'
MaxConnections = '1'
ReopenSecs = '300'
NetTimeout = '30'
RedoCompression = 'DISABLE'
LogShipping = 'ON'
PreferredApplyInstance = ''
ApplyInstanceTimeout = '0'
ApplyParallel = 'AUTO'
StandbyFileManagement = 'auto'
ArchiveLagTarget = '0'
LogArchiveMaxProcesses = '4'
LogArchiveMinSucceedDest = '1'
DbFileNameConvert = ''
LogFileNameConvert = ''
FastStartFailoverTarget = ''
InconsistentProperties = '(monitor)'
InconsistentLogXptProps = '(monitor)'
SendQEntries = '(monitor)'
LogXptStatus = '(monitor)'
RecvQEntries = '(monitor)'
SidName = 'orcl'
StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=masicong)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl_pd_DGMGRL)(INSTANCE_NAME=orcl)(SERVER=DEDICATED)))'
StandbyArchiveLocation = '/u01/archivelog'
AlternateLocation = ''
LogArchiveTrace = '0'
LogArchiveFormat = '%t_%s_%r.dbf'
TopWaitEvents = '(monitor)'
Database Status:
SUCCESS
如果有报错或需要可以单独编辑其中内容
edit database 'orcl_st' set property 'ArchiveLagTarget'='0'; edit database 'orcl_st' set property 'LogArchiveMaxProcesses'='4'; edit database 'orcl_st' set property 'LogArchiveMinSucceedDest'='1';
2.查看备库信息
DGMGRL> show database verbose 'orcl_st';
Database - orcl_st
Role: PHYSICAL STANDBY
Intended State: APPLY-ON
Transport Lag: (unknown)
Apply Lag: (unknown)
Real Time Query: OFF
Instance(s):
orcm
Properties:
DGConnectIdentifier = 'orcl_st'
ObserverConnectIdentifier = ''
LogXptMode = 'SYNC'
DelayMins = '0'
Binding = 'OPTIONAL'
MaxFailure = '0'
MaxConnections = '1'
ReopenSecs = '300'
NetTimeout = '30'
RedoCompression = 'DISABLE'
LogShipping = 'ON'
PreferredApplyInstance = ''
ApplyInstanceTimeout = '0'
ApplyParallel = 'AUTO'
StandbyFileManagement = 'auto'
ArchiveLagTarget = '0'
LogArchiveMaxProcesses = '4'
LogArchiveMinSucceedDest = '1'
DbFileNameConvert = '/u01/app/oracle/oradata/orcl, /u01/app/oracle/oradata/orcm'
LogFileNameConvert = '/u01/app/oracle/oradata/orcl, /u01/app/oracle/oradata/orcm'
FastStartFailoverTarget = ''
InconsistentProperties = '(monitor)'
InconsistentLogXptProps = '(monitor)'
SendQEntries = '(monitor)'
LogXptStatus = '(monitor)'
RecvQEntries = '(monitor)'
SidName = 'orcm'
StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=masicong)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl_st_DGMGRL)(INSTANCE_NAME=orcm)(SERVER=DEDICATED)))'
StandbyArchiveLocation = '/u01/archivelog'
AlternateLocation = ''
LogArchiveTrace = '0'
LogArchiveFormat = '%t_%s_%r.dbf'
TopWaitEvents = '(monitor)'
Database Status:
SUCCESS
3.启动fast_start
DGMGRL> enable fast_start failover;
4.启用fast_start如果报警告，是因为需要先在别的机器启动start observer。start observer需要单独在服务器上启动，在后台自动运行，不能关闭，否则主备库就无法自动监控运行状态。就无法使用快速启动故障转移功能。
