Oracle单实例ASM搭建DG_BROKER(Linux7.4_19C)

2024-06-03 22:48

本文主要是介绍Oracle单实例ASM搭建DG_BROKER(Linux7.4_19C),希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!

1、检测准备库是否能正常切换

主库:
alter database commit to switchover to physical standby with session shutdown;备库:
alter database commit to switchover to primary with session shutdown;
alter database open;主库:
startup;

2、确保主备库都是spfile启动

主库:
SYS@dgpri>show parameter spfile;NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
spfile				     string	 +DATA/ZZZDGPRI/parameterfile/spfile.276.1025373149**备库:**
SYS@dgphy>show parameter spfile;NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
spfile				     string	 +DATADG/ZZZDGPHY/parameterfile/spfile.258.1025389845

3、修改dg_broker_start参数为TRUE

主库:
SYS@dgpri>show parameter dg_broker;NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
dg_broker_config_file1		     string	 /u01/app/oracle/product/19.2.0.0.0/dbhome_1/dbs/dr1ZZZDGPRI.dat
dg_broker_config_file2		     string	 /u01/app/oracle/product/19.2.0.0.0/dbhome_1/dbs/dr2ZZZDGPRI.dat
dg_broker_start 		     boolean	 FALSESYS@dgpri>alter system set dg_broker_start = true;System altered.SYS@dgpri>host ps -ef | grep dmon
oracle   35590     1  0 18:39 ?        00:00:00 ora_dmon_dgpri
oracle   35639  9449  0 18:39 pts/2    00:00:00 /bin/bash -c ps -ef | grep dmon
oracle   35641 35639  0 18:39 pts/2    00:00:00 grep dmon备库:
SYS@dgphy>show parameter dg_broker;NAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
dg_broker_config_file1		     string	 /u01/app/oracle/product/19.2.0.0.0/dbhome_1/dbs/dr1ZZZDGPHY.dat
dg_broker_config_file2		     string	 /u01/app/oracle/product/19.2.0.0.0/dbhome_1/dbs/dr2ZZZDGPHY.dat
dg_broker_start 		     boolean	 FALSESYS@dgphy>alter system set dg_broker_start = true;System altered.SYS@dgphy>host ps -ef | grep dmon
oracle   14377     1  0 18:39 ?        00:00:00 ora_dmon_dgphy
oracle   14410  8169  0 18:40 pts/2    00:00:00 /bin/bash -c ps -ef | grep dmon
oracle   14412 14410  0 18:40 pts/2    00:00:00 grep dmon

4、修改dg_broker参数文件位置

主库:
SYS@dgpri>alter system set dg_broker_config_file1 = '+DATA/dr1ZZZDGPRI.dat' scope = spfile;System altered.SYS@dgpri>alter system set dg_broker_config_file2 = '+DATA/dr2ZZZDGPRI.dat' scope = spfile;System altered.备库:
SYS@dgphy>alter system set dg_broker_config_file1 = '+DATADG/dr1ZZZDGPHY.dat' scope = spfile;System altered.SYS@dgphy>alter system set dg_broker_config_file2 = '+DATADG/dr2ZZZDGPHY.dat' scope = spfile;System altered.

重启主备库

5、配置DG_BROKER监听和TNS

可以使用默认监听,也可以创建一个非默认监听,这里使用默认监听。查看domain,如果存在则需要在服务后加上domain后缀
SYS@dgpri>show parameter domainNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
db_domain			     string**配置LISTENER**主库:
[grid@kkk admin]$ cat listener.ora
#Backup file is  /u01/app/grid/crsdata/kkk/output/listener.ora.bak.kkk.grid line added by Agent
# listener.ora Network Configuration File: /u01/app/19.2.0.0.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.16)(PORT = 1521))))SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)(GLOBAL_DBNAME=ZZZDGPRI)(SID_NAME=dgpri))(SID_DESC=(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)(GLOBAL_DBNAME=ZZZDGPRI_DGMGRL)		#DG_BROKER专用服务名(SID_NAME=dgpri)))ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON		# line added by Agent
VALID_NODE_CHECKING_REGISTRATION_LISTENER=ON		# line added by Agent备库:[grid@hhh admin]$ cat listener.ora 
#Backup file is  /u01/app/grid/crsdata/hhh/output/listener.ora.bak.hhh.grid line added by Agent
# listener.ora Network Configuration File: /u01/app/19.2.0.0.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.17)(PORT = 1521))))SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)(GLOBAL_DBNAME=ZZZDGPHY)(SID_NAME=dgphy))(SID_DESC=(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)(GLOBAL_DBNAME=ZZZDGPHY_DGMGRL)(SID_NAME=dgphy)))ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON		# line added by Agent
VALID_NODE_CHECKING_REGISTRATION_LISTENER=ON		# line added by Agent添加后lsnrctl reload配置TNS主备库tnsnames.ora文件添加如下TNS_ZZZDGPRI_DGMGRL=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.16)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = ZZZDGPRI_DGMGRL)))TNS_ZZZDGPHY_DGMGRL=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.17)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = ZZZDGPHY_DGMGRL)))

6、配置DG_BROKER参数文件

DGMGRL> create configuration c1 as primary database is ZZZDGPRI connect identifier is TNS_ZZZDGPRI_DGMGRL
> ;**12c环境直接添加备库会报错,清空log_archive_dest_n**
DGMGRL> add database ZZZDGPHY as connect identifier is TNS_ZZZDGPHY_DGMGRL maintained as PHYSICAL;
Error: ORA-16698: member has a LOG_ARCHIVE_DEST_n parameter with SERVICE attribute set#清空主备库log_archive_dest_n参数DGMGRL> add database ZZZDGPHY as connect identifier is TNS_ZZZDGPHY_DGMGRL maintained as PHYSICAL;
