★ 创建测试目录
//////////////////////////////////////////
su - oracle
mkdir -p /home/oracle/zzt_backup/
★ 进行全库备份
//////////////////////////////////////////
SQL> shutdown immediate
SQL> startup mount
RMAN> run{
allocate channel zzt_disk01 device type disk;
allocate channel zzt_disk02 device type disk;
allocate channel zzt_disk03 device type disk;
#数据文件
backup incremental level 0 database tag zzt_lvl0_data
format '/home/oracle/zzt_backup/zzt_lvl0_data_%d_%T_%u.dbf' ;
#归档文件
sql 'alter system archive log current';
sql 'alter system archive log current';
sql 'alter system archive log current';
backup archivelog all delete input tag zzt_lvl0_arch
format '/home/oracle/zzt_backup/zzt_lvl0_arch_%d_%T_%u_%e.arc' ;
#控制文件
backup current controlfile tag zzt_lvl0_ctlf
format '/home/oracle/zzt_backup/zzt_lvl0_ctlf_%d_%T_%u.ctl' ;
#参数文件
backup spfile tag zzt_lvl0_spfi

}
★ ASM磁盘组迁移指导
//////////////////////////////////////////
※ 新旧ASM磁盘组迁移方向
+DATA → +NDATA
+FRA → +NFRA
★ 用RMAN迁移参数文件+控制文件到新ASM磁盘组
//////////////////////////////////////////
RMAN> run{
allocate channel zzt_disk01 device type disk;
restore spfile to '+NDATA/spfile.ora';
restore controlfile to '+NDATA/ctrl01.dbf';
restore controlfile to '+NFRA/ctrl02.dbf';
release channel zzt_disk01;
}
★ 查看当前数据库redo信息，以便后期完全恢复时参考
//////////////////////////////////////////
SQL> select * from v$log;
SQL> select * from v$logfile;
SQL> shutdown immediate
★ 修改RAC中DB的参数文件到新位置
//////////////////////////////////////////
[root ]# su - oracle
[oracle]$ cd $ORACLE_HOME/dbs/
[oracle]$ vi initXXX.ora 【此处的XXX为数据库节点实例名】
SPFILE='+NDATA/spfile.ora'
★ 修改RAC中DB的控制文件到新位置
//////////////////////////////////////////
SQL> startup mount
SQL> alter system set db_recovery_file_dest='+NFRA' scope=both sid='*';
SQL> alter system set control_files='+NDATA/ctrl01.dbf','+NFRA/ctrl02.dbf' scope=spfile sid='*';
SQL> startup mount force
SQL> show parameter spfile
SQL> show parameter control_files
SQL> show parameter db_recovery_file_dest
★ 使用RMAN备份将数据库恢复到到新ASM磁盘组
//////////////////////////////////////////
RMAN> run{
allocate channel zzt_disk01 device type disk;
allocate channel zzt_disk02 device type disk;
allocate channel zzt_disk03 device type disk;
set newname for database to '+NDATA';
restore database;
switch datafile all;
switch tempfile all;
release channel zzt_disk01;
release channel zzt_disk02;
release channel zzt_disk03;
}
SQL> select name from v$datafile;
★ 修改归档路径并使用RMAN备份进行数据库恢复
//////////////////////////////////////////
注意：如果RMAN检测到一个归档的重做日志已存在，就不会在磁盘上还原这个归档的重做日志，即使设置的还原位置不同与默认的归档日志位置，Oracle 也不会在这个新的位置上恢复归档的重做日志。
RMAN> run{
allocate channel zzt_disk01 device type disk;
allocate channel zzt_disk02 device type disk;
allocate channel zzt_disk03 device type disk;
set archivelog destination to '+NFRA';
#restore archivelog all;
recover database;
release channel zzt_disk01;
release channel zzt_disk02;
release channel zzt_disk03;
}
※ 查看归档的相关信息
SQL>
select * from (select thread#,SEQUENCE#,name from v$archived_log order by thread#,SEQUENCE#) where thread#=1 and rownum<5
union
select * from (select thread#,SEQUENCE#,name from v$archived_log order by thread#,SEQUENCE#) where thread#=2 and rownum<5
;
★ 验证数据库完整性并起库
//////////////////////////////////////////
※ 根据之前的控制文件中记录的redo在线日志信息（v$log/v$logfile）来判断数据库是否可以并执行了完全恢复
※ 对比查看rman执行“recover database”恢复时，有没有恢复current组的在线日志
① 如果有恢复，则直接resetlogs起库即可；
SQL> alter database open resetlogs;
② 如果没有恢复，则使用下面的方法手动指定相关在线日志文件进行恢复，然后起库
SQL> recover database using backup controlfile until cancel;
+DATA/{DB_NAME}/onlinelog/{group_1.261.952947745}
【输入没有备份的在线日志文件进行完全恢复】
【如果选择的redo在线日志选择正确则输出：“Log applied.”】
【如果选择的redo在线日志选择错误则输出：“ORA-00325”】
SQL> alter database open resetlogs;
★ 修改redo日志相关信息
//////////////////////////////////////////
※ 具体执行步骤参考网文：https://www.cnblogs.com/xqzt/p/5034826.html
alter database add logfile thread 1 group 5 ('+NDATA','+NFRA') size 50M;
alter database add logfile thread 1 group 6 ('+NDATA','+NFRA') size 50M;
alter database add logfile thread 2 group 7 ('+NDATA','+NFRA') size 50M;
alter database add logfile thread 2 group 8 ('+NDATA','+NFRA') size 50M;
alter system switch logfile;
alter database drop logfile group 1;
alter database drop logfile group 2;
alter database drop logfile group 3;
alter database drop logfile group 4;
★ 修改临时表空间相关信息
//////////////////////////////////////////
SQL> create temporary tablespace temp2 tempfile '+ndata' size 10m autoextend on;
SQL> alter database default temporary tablespace temp2;
SQL> drop tablespace temp including contents and datafiles;
至此整个数据库操作执行完成，感谢您的观看。以下为相关日志输出，仅供参考
