DG Broker搭建
1.环境说明
databaseddb _ name db _ unique _ namenetservice名称primaryogoglogg _ p物理2.查看参数站
----主库
SYS@oggshow parameter broker
名称类型值
- - -
DG _ broker _ config _ file 1 string/u01/app/Oracle/product/11。2 .0/dbhome _ 1/DBS/dr1 ogg。数字式录音带(digital audio tape)DOS文件名数据文件
DG _ broker _ config _ file 2 string/u01/app/Oracle/product/11。2 .0/dbhome _ 1/DBS/dr2 ogg。数字式录音带(digital audio tape)DOS文件名数据文件
dg _代理_开始布尔值错误的
----备库
SYS@dogg show parameter broker
名称类型值
- - -
DG _ broker _ config _ file 1 string/u01/app/Oracle/product/11。2 .0/db _ 1/DBS/dr1 dog。数字式录音带(digital audio tape)DOS文件名数据文件
DG _ broker _ config _ file 2 string/u01/app/Oracle/product/11。2 .0/db _ 1/DBS/dr2 dog。数字式录音带(digital audio tape)DOS文件名数据文件
dg _代理_开始布尔值错误的
------修改dg_broker_config_file参数。这里就用默认的路径，也可以自己指定。如果是在RAC环境中，这个把这个文件把到共享的存储上面，如果有ASM可以放到ASM中。

3.启用BROKER
----在两个数据库上面都执行：
alter system set dg_broker_start=true scope=both;
4.登录配置
---在其中任意一台做下面的操作就可以了，另它安装了client的客户端也是可以的
[oracle@ogg-80 ~]$ dgmgrl
（1）连接到当前的主数据库
DGMGRL> connect sys/oracle@ogg_p
DGMGRL> help create -----查看帮助
Creates a broker configuration
Syntax:
CREATE CONFIGURATION <configuration name> AS
PRIMARY DATABASE IS <database name>
CONNECT IDENTIFIER IS <connect identifier>;
（2）创建一个配置文件(ogg是db_unique_name，oggDG是配置的名字--可以修改，ogg_p是连接到prod数据库的tnsname）
create configuration oggDG as primary database is ogg connect identifier is ogg_p;
（3）启用配置文件
DGMGRL> enable configuration;
（4）增加备库到配置文件中 (dogg是备机的db_unique_name，dogg_s是连接到sprod数据库的tnsname）
DGMGRL> add database dogg as connect identifier is dogg_s;
（5）启用备库
DGMGRL> enable database dogg;
（6）查看配置文件
DGMGRL> show configuration
Configuration - oggdg
Protection Mode: MaxPerformance
Databases:
ogg - Primary database
dogg - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
（7）查看主库的配置消息
DGMGRL> show database verbose ogg;
Database - ogg
Role: PRIMARY
Intended State: TRANSPORT-ON
Instance(s):
ogg
Properties:
DGConnectIdentifier = 'ogg_p'
ObserverConnectIdentifier = ''
LogXptMode = 'ASYNC'
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/dogg/, /u01/app/oracle/oradata/ogg/'
LogFileNameConvert = '/u01/app/oracle/oradata/dogg/, /u01/app/oracle/oradata/ogg/'
FastStartFailoverTarget = ''
InconsistentProperties = '(monitor)'
InconsistentLogXptProps = '(monitor)'
SendQEntries = '(monitor)'
LogXptStatus = '(monitor)'
RecvQEntries = '(monitor)'
ApplyLagThreshold = '0'
TransportLagThreshold = '0'
TransportDisconnectedThreshold = '30'
SidName = 'ogg'
StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=ogg-80)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ogg_DGMGRL)(INSTANCE_NAME=ogg)(SERVER=DEDICATED)))'
StandbyArchiveLocation = '/u01/app/oracle/archive'
AlternateLocation = ''
LogArchiveTrace = '0'
LogArchiveFormat = '%t_%s_%r.dbf'
TopWaitEvents = '(monitor)'
Database Status:
SUCCESS
（8）查看备库的配置消息
DGMGRL> show database verbose dogg;
Database - dogg
Role: PHYSICAL STANDBY
Intended State: APPLY-ON
Transport Lag: 0 seconds (computed 0 seconds ago)
Apply Lag: 0 seconds (computed 0 seconds ago)
Apply Rate: 0 Byte/s
Real Time Query: ON
Instance(s):
dogg
Properties:
DGConnectIdentifier = 'dogg_s'
ObserverConnectIdentifier = ''
LogXptMode = 'ASYNC'
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/ogg/, /u01/app/oracle/oradata/dogg/'
LogFileNameConvert = '/u01/app/oracle/oradata/ogg/, /u01/app/oracle/oradata/dogg/'
FastStartFailoverTarget = ''
InconsistentProperties = '(monitor)'
InconsistentLogXptProps = '(monitor)'
SendQEntries = '(monitor)'
LogXptStatus = '(monitor)'
RecvQEntries = '(monitor)'
ApplyLagThreshold = '0'
TransportLagThreshold = '0'
TransportDisconnectedThreshold = '30'
SidName = 'dogg'
StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=d-ogg)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=dogg_DGMGRL)(INSTANCE_NAME=dogg)(SERVER=DEDICATED)))'
StandbyArchiveLocation = '/u01/app/oracle/archive'
AlternateLocation = ''
LogArchiveTrace = '0'
LogArchiveFormat = '%t_%s_%r.dbf'
TopWaitEvents = '(monitor)'
Database Status:
SUCCESS
（9）修改StaticConnectIdentifier参数，记得两个数据库都要修改。
DGMGRL> edit database ogg set property StaticConnectIdentifier='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.80)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=ogg)(SERVER=DEDICATED)))';
DGMGRL> edit database dogg set property StaticConnectIdentifier='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.90)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=dogg)(SERVER=DEDICATED)))';
（10）开始切换
DGMGRL> switchover to dogg;
Performing switchover NOW, please wait...
Operation requires a connection to instance "dogg" on database "dogg"
Connecting to instance "dogg"...
Connected.
New primary database "dogg" is opening...
Operation requires startup of instance "ogg" on database "ogg"
Starting instance "ogg"...
ORACLE instance started.
Database mounted.
Database opened.
Switchover succeeded, new primary is "dogg"
（11）查看状态
DGMGRL> show configuration;
Configuration - oggdg
Protection Mode: MaxPerformance
Databases:
dogg - Primary database
ogg - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
（12）再次切换回去
DGMGRL> switchover to ogg;
