19c 数据高可用实用配置 RAC + SingleADG

 

一、     环境介绍

二、     操作步骤

2.1.   配置静态LISTENER.ORA监听

RAC各个节点按如下配置:

 

[oracle@ora19crac1 ~]$ vi $ORACLE_HOME/network/admin/listener.ora
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = scan-ora19cracdb)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = woo_DGMGRL)
      (ORACLE_HOME =/u01/app/oracle/product/19.3.0/dbhome_1)
      (SID_NAME = woo)
    )
  )
 
[oracle@ora19crac2 ~]$ cat $ORACLE_HOME/network/admin/listener.ora
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = scan-ora19cracdb)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = woo_DGMGRL)
      (ORACLE_HOME =/u01/app/oracle/product/19.3.0/dbhome_1)
      (SID_NAME = woo)
    )
  )

 

 

单实例节点配置:

 

[oracle@ora19cadg ~]$ cat $ORACLE_HOME/network/admin/listener.ora
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = ora19cadg)(PORT = 1521))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )
 
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = woo_DGMGRL)
      (ORACLE_HOME =/u01/app/oracle/product/19.3.0/dbhome_1)
      (SID_NAME = woo)
    )
  )

2.2.   配置TNSNAME.ora网络连接文件

所有节点配置如下:

 

[oracle@ora19crac1 ~]$ cat $ORACLE_HOME/network/admin/tnsnames.ora 
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/19.3.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
 
WOO =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = scan-ora19cracdb)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = woo)
    )
  )
 
 
WOOSTY =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.84.99)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = woosty)
      (UR=A)
    )
  )

2.3.   所有节点在hosts中添加如下解析

 

[root@ora19cadg ~]# tail -2 /etc/hosts
192.168.84.95                   scan-ora19cracdb
192.168.84.99                   ora19cadg

2.4.   开启归档和force logging

需要关闭一个实例,在一个实例上做以下操作即可:

 

SQL> alter database force logging;
 
Database altered.
 
SQL> alter system set db_recovery_file_dest='+FRA_GP01' scope=spfile sid='*';
 
System altered.
 
SQL> alter system set DB_RECOVERY_FILE_DEST_SIZE=2g scope=spfile sid='*';
 
System altered.
 
SQL> shut immediate
SQL> startup mount;
ORACLE instance started.
 
Total System Global Area  805304088 bytes
Fixed Size                  9139992 bytes
Variable Size             394264576 bytes
Database Buffers          394264576 bytes
Redo Buffers                7634944 bytes
Database mounted.
SQL> alter database archivelog;
 
Database altered.
 
SQL> alter database open;
 
Database altered.
 
SQL> alter database flashback on;
 
Database altered.
 
SQL> col force_logging format a10
SQL> select name,open_mode,database_role,flashback_on,force_logging from v$database;
 
NAME      OPEN_MODE            DATABASE_ROLE    FLASHBACK_ON       FORCE_LOGG
--------- -------------------- ---------------- ------------------ ----------
WOO       READ WRITE           PRIMARY          YES                YES

2.5.   检查初始化参数文件

 

SQL> show parameter db_name
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_name                              string      woo
 
SQL> show parameter uniq
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
db_unique_name                       string      woo

2.6.   配置RAC端主库参数

 

ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(woo,woosty)' sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=woo' sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=woosty ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=woosty' sid='*';
ALTER SYSTEM SET db_file_name_convert='/DBSoft/oracle/oradata/woo/','+DATA_GP01/WOO/'scope=spfile sid='*';
ALTER SYSTEM SET log_file_name_convert='/DBSoft/oracle/oradata/woo/','+DATA_GP01/WOO/ONLINELOG/' scope=spfile sid='*';
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO sid='*';
ALTER SYSTEM SET FAL_SERVER='woosty';

2.7.   开启Broker

 

SQL> alter system set dg_broker_start=true;
 
System altered.

2.8.   添加standby日志组

 

SQL> alter database add standby logfile 
  2  group 5 ('+DATA_GP01/WOO/ONLINELOG/group_5.log') size 200m;
 
Database altered.
 
SQL> alter database add standby logfile 
  2  group 6 ('+DATA_GP01/WOO/ONLINELOG/group_6.log') size 200m;
 
Database altered.
 
SQL> alter database add standby logfile 
  2  group 7 ('+DATA_GP01/WOO/ONLINELOG/group_7.log') size 200m;
 
Database altered.
 
SQL> alter database add standby logfile 
  2  group 8 ('+DATA_GP01/WOO/ONLINELOG/group_8.log') size 200m;
 
Database altered.
 
SQL> alter database add standby logfile 
  2  group 9 ('+DATA_GP01/WOO/ONLINELOG/group_9.log') size 200m;
 
Database altered.
 
SQL> select group#,status,type from v$logfile;
 
    GROUP# STATUS  TYPE
---------- ------- -------
         2         ONLINE
         1         ONLINE
         3         ONLINE
         4         ONLINE
         5         STANDBY
         6         STANDBY
         7         STANDBY
         8         STANDBY
         9         STANDBY
 
9 rows selected.

2.9.   备库创建相应目录

 

[oracle@ora19cadg ~]$ mkdir -p /DBSoft/oracle/oradata/woo/pdbseed
[oracle@ora19cadg ~]$ mkdir -p /DBSoft/oracle/fast_recovery_area/woo
[oracle@ora19cadg ~]$ mkdir -p /DBSoft/oracle/admin/woo/adump

 

2.10. 手工创建备库参数文件和密码文件

 

[oracle@ora19cadg dbs]$ cat initwoo.ora 
*.audit_file_dest='/DBSoft/oracle/admin/woo/adump'
*.audit_trail='db'
*.cluster_database=false
*.compatible='19.0.0'

*.db_name='woo'
*.db_recovery_file_dest='/DBSoft/oracle/fast_recovery_area/woo'
*.DB_RECOVERY_FILE_DEST_SIZE = 2g
*.diagnostic_dest='/DBSoft/oracle'
*.enable_pluggable_database=true
*.DB_UNIQUE_NAME=woosty
*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(woo,woosty)'
*.LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=woosty'
*.LOG_ARCHIVE_DEST_2='SERVICE=woo ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=woo'
*.db_file_name_convert='+DATA_GP01/WOO/','/DBSoft/oracle/oradata/woo/'
*.log_file_name_convert='+DATA_GP01/WOO/ONLINELOG/','/DBSoft/oracle/oradata/woo/'
*.STANDBY_FILE_MANAGEMENT=AUTO
*.FAL_SERVER='woo'
 
[oracle@ora19cadg dbs]$ orapwd file=orapwwoo password=oracle entries=10
