rman连接cdb，备份整个数据库
run{ allocate channel C1 device type disk format '/home/oracle/backup/full_db_%U'; backup database include current controlfile plus archivelog ; release channel C1 ; } crosscheck backupset; delete noprompt obsolete;
或者
backup database include current controlfile format '/home/oracle/backup/full_db_%U' plus archivelog format '/home/oracle/backup/full_db_%U';
结果如下：

模拟pdb库全库恢复
首先删除一个数据文件
SQL> !rm /data/app/oracle/oradata/orcl/pdborcl/pdborcl_users01.dbf
打开pdborcl，报错如下
SQL> alter pluggable database pdborcl open; alter pluggable database pdborcl open * ERROR at line 1: ORA-01157: cannot identify/lock data file 10 - see DBWR trace file ORA-01110: data file 10: '/data/app/oracle/oradata/orcl/pdborcl/pdborcl_users01.dbf'
基于cdb恢复pdb库
连接rman
[oracle@xqzt ~]$ rman target /
