Oracle Linux环境单实例迁移到RAC集群
Oracle Linux环境单实例迁移到RAC集群
- 一、RMAN手动还原备份集方式
- 二、RMAN DUPLICATE方式
一、RMAN手动还原备份集方式
1.1 迁移环境
源数据库
操作系统：CentsOS 7.2
Oracle数据库版本：11.2.0.4 单实例
ORACLE_SID：ORCL
DB_NAME:ORCL
目标数据库
操作系统：CentOS 7.5
Oracle数据库版本：11.2.0.4 RAC
ORACLE_SID：ORCL
DB_NAME:ORCL
1.2 迁移准备
1、在迁移前需要在单实例数据库做好RMAN全备，以及归档日志备份。在RAC环境还原时需要考虑pfile中控制文件的路径。
2、此案例中rac环境的实例名、DBNAME与源数据库均相同。如迁移完毕，可将旧数据文件从ASM中删除
1.3 迁移步骤
1.3.1 源服务器做RMAN全备
rman target /
run
{
allocate channel c1 device type disk;
allocate channel c2 device type disk;
backup database filesperset 2 format '/u01/rman/full_%d_%U.bak';
backup archivelog all format '/u01/rman/arch_%d_%U.bak';
release channel c1;
release channel c2;
}
1.3.2 查看备份集
ll /u01/rman
[root@gs oracle]# ll /u01/rman -hrt
总用量 2.0G
-rw-r----- 1 oracle oinstall 768M 11月 12 11:44 full_ORCL_7jti1ekt_1_1.bak
-rw-r----- 1 oracle oinstall 946M 11月 12 11:44 full_ORCL_7iti1ekt_1_1.bak
-rw-r----- 1 oracle oinstall 4.2M 11月 12 11:44 full_ORCL_7kti1elc_1_1.bak
-rw-r----- 1 oracle oinstall 96K 11月 12 11:44 full_ORCL_7mti1ele_1_1.bak
-rw-r----- 1 oracle oinstall 18M 11月 12 11:44 full_ORCL_7lti1elc_1_1.bak
-rw-r----- 1 oracle oinstall 12M 11月 12 11:44 arch_ORCL_7oti1elf_1_1.bak
-rw-r----- 1 oracle oinstall 252M 11月 12 11:44 arch_ORCL_7nti1elf_1_1.bak
-rw-r----- 1 oracle oinstall 8.0K 11月 12 11:44 arch_ORCL_7pti1elh_1_1.bak
1.3.3 拷贝备份到目标RAC数据库服务器
scp /u01/rman/* oracle@172.16.4.41:/u01/rman
1.3.4 在目标RAC数据库检查文件目录权限
RMAN备份目录
chown -R oracle:oinstall /u01/rman
adump目录
mkdir -p /u01/app/oracle/admin/orcl/adump/
1.3.5 rac数据库修改集群参数为false
$ sqlplus / as sysdba;
SQL> alter system set cluster_database=true scope=spfile sid='*';
1.3.6 生成pfile文件
create pfile from spfile;
1.3.7 关闭rac数据库
srvctl stop database -d orcl
1.3.8 修改rac数据库pfile参数
su - oracle
vi $ORACLE_HOME/dbs/initorcl1.ora
*.audit_file_dest='/u01/app/oracle/admin/orcl/adump'
*.audit_trail='none'
*.cluster_database=FALSE
*.compatible='11.2.0.4.0'
*.control_files='+DATA/orcl/controlfile/control1.ctl'
*.db_block_size=8192
*.db_create_file_dest='+DATA'
*.db_domain=''
*.db_name='orcl'
*.diagnostic_dest='/u01/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
*.memory_target=830472192
*.open_cursors=300
*.processes=150
*.remote_listener='rac-scan:1521'
*.remote_login_passwordfile='exclusive'
*.sessions=170
*.LOG_ARCHIVE_DEST_1='LOCATION=+data'
备注：需要注意控制文件以及归档日志文件的目录参数
1.3.9 目标rac数据库启动到nomount
sqlplus / as sysdba
startup nomount;
1.3.10 还原控制文件
[oracle@rac1 ~]$ rman target /
RMAN> restore controlfile from '/u01/rman/full_ORCL_7lti1elc_1_1.bak';

Finished restore at 2018/11/09 15:22:56
1.3.11 数据库启动到mount状态
RMAN> alter database mount;
1.3.12 手动注册备份集目录到控制文件
RMAN> crosscheck backupset;
RMAN> catalog start with '/u01/rman';
RMAN> list backupset summary;
1.3.13 查看控制文件中数据文件、日志文件目录

set newname for datafile 1 to '+DATA';
set newname for datafile 2 to '+DATA';
set newname for datafile 3 to '+DATA';
set newname for datafile 4 to '+DATA';

单实例迁移到RAC环境完毕
二、RMAN DUPLICATE方式
2.1 迁移环境

操作系统：CentsOS 7.2
Oracle数据库版本：11.2.0.4 单实例
ORACLE_SID：ORCL
DB_NAME:ORCL
目标数据库
操作系统：CentOS 7.5
Oracle数据库版本：11.2.0.4 RAC
ORACLE_SID：ORCL
DB_NAME:ORCL
2.2 迁移准备
1、在迁移前需要在单实例数据库做好RMAN全备，以及归档日志备份。在RAC环境还原时需要考虑pfile中控制文件的路径。
2、rman还原之后需要做如下动作
生成asm的spfile
恢复rac环境的集群参数
恢复节点2undo表空间
增加节点2 thread日志组
在srvctl组件中增加数据库节点
