本篇内容介绍了“分析SQL中的RAC+DataGuard Broker”的有关知识,在实际案例的操作过程中,不少人都会遇到这样的困境,接下来就让小编带领大家学习一下如何处理这些情况吧!希望大家仔细阅读,能够学有所成!
前言:
在备库需要清理昨天的环境:
SQL> alter system set log_archive_dest_2='';
System altered.
一、主备库启用Broker特性
主:
SQL> alter system set dg_broker_start=true;
System altered.
备:
SQL> alter system set dg_broker_start=true;
System altered.
SQL> show parameter dg
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
adg_account_info_tracking string LOCAL
adg_redirect_dml boolean FALSE
cell_offloadgroup_name string
dg_broker_config_file1 string /u01/app/oracle/product/19.3.0
/dbhome_1/dbs/dr1woo.dat
dg_broker_config_file2 string /u01/app/oracle/product/19.3.0
/dbhome_1/dbs/dr2woo.dat
dg_broker_start boolean TRUE
inmemory_adg_enabled boolean TRUE /dbhome_1/dbs/dr1woo.datdg_broker_config_file2 string /u01/app/oracle/product/19.3.0 /dbhome_1/dbs/dr2woo.datdg_broker_start boolean TRUEinmemory_adg_enabled boolean TRUE
二、登录Broker命令行DGMGRL
dgmgrl sys/oracle@woo
三、创建Primary库
DGMGRL> CREATE CONFIGURATION dg_config AS PRIMARY DATABASE IS woo CONNECT IDENTIFIER IS woo;
Configuration "dg_config" created with primary database "woo"
三、创建standby备库
DGMGRL> ADD DATABASE woosty AS CONNECT IDENTIFIER IS woosty MAINTAINED AS PHYSICAL;
Database "woosty" added
四、启用配置
DGMGRL> ENABLE CONFIGURATION;
Enabled.
五、查看配置
DGMGRL> show configuration;
Configuration - dg_config
Protection Mode: MaxPerformance
Members:
woo - Primary database
Fast-Start Failover: Disabled
Configuration Status:
SUCCESS (status updated 0 seconds ago)
六、查看主库信息
DGMGRL> SHOW DATABASE woo;
Database - woo
Role: PRIMARY
Intended State: TRANSPORT-ON
Instance(s):
woo1
woo2
Database Status:
SUCCESS
七、查看备库信息
DGMGRL> show configuration;
Configuration - dg_config
Protection Mode: MaxPerformance
Members:
woo - Primary database
woosty - Physical standby database
Fast-Start Failover: Disabled
Configuration Status:
SUCCESS (status updated 45 seconds ago)
八、故障诊断
DGMGRL> show database woo statusreport;
STATUS REPORT
INSTANCE_NAME SEVERITY ERROR_TEXT
DGMGRL> show database woosty statusreport;
STATUS REPORT
INSTANCE_NAME SEVERITY ERROR_TEXT
