一、 环境介绍
主库 | 备库 | |
架构 |
| 单机 |
操作系统 | RedHat Linux 7.7 x64 | RedHat Linux 7.7 x64 |
数据库版本 | Oracle 19.3 | Oracle 19.3 |
IP地址 | 192.168.84.91 | 192.168.84.92 |
SID | woo1 | woo2 | woo |
DB_NAME | woo | woo |
DB_UNIQU_NAME | woo_pri | woosty |
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

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' *.control_files='/DBSoft/oracle/oradata/woo/control01.ctl' *.db_block_size=8192 *.db_create_file_dest='/DBSoft/oracle/oradata/woo' *.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 OPW-00029: Password complexity failed for SYS user : Password must contain at least 8 characters.
