12C RMAN 备份参考v1
windows bat
1,C:\dba\utility\rman\rman.bat
del C:\dba\utility\rman\full_db_* /q
set TNSNAME=ceipuat
rman target /@%TNSNAME% cmdfile=C:\dba\utility\rman\rman.cmd
2.C:\dba\utility\rman\rman.cmd
backup filesperset = 5 as compressed backupset database format 'C:\dba\utility\rman\full_db_%U' plus archivelog delete all input format 'C:\dba\utility\rman\full_db_arch_%U';
step 0:
backup scripts:
backup filesperset = 5 as compressed backupset database format 'C:\dba\utility\rman\full_db_%U' plus archivelog delete all input format 'C:\dba\utility\rman\full_db_arch_%U';
Step 1: 重启服务器后，oracle 会自动拉起，不需要 操作。
检查健康方法：
确认以下服务的状态是 正在运行 的状态
OracleService****
OracleOraDB11gHome1TNSListener***
Step 2:
确定数据库文件的目录都存在 （C:\APP\ORACLE\ORADATA\sid\pdb_name or PDBSEED）
rman target /
restore controlfile from autobackup;
(或者指定的有控制文件 备份的备份集)
alter database mount;
restore database;
restore arachivelog all;
recover database;
shutdown immediate;
startup mount;
alter database open resetlogs;
12C引进了pdb的概念,使得rman的恢复相对来说复杂了一些,这里对pdb的常规备份和恢复进行了简单测试,供大家参考
1.cdb启动和pdb关系测试

证明直接startup cdb里面的pdb不会自动open,需要手工进行open
2.rman使用cdb备份数据库

[oracle@ora12c cdb]$ cp -r pdb1 pdb_bak
3.删除pdb1
[oracle@ora12c cdb]$ rm -rf pdb1
4.把pdb1数据库open
