对38号文件执行介质恢复

在对38号文件进行介质恢复后打开CDB时提示39号文件也需要进行介质恢复

如是执行recover database命令来对CDB进行介质恢复并打开CDB
SQL> recover database; Media recovery complete. SQL> alter database open; Database altered.
在打开JYPDB时提示PDB的45号文件需要进行介质恢复

SQL> recover datafile 45; Media recovery complete. SQL> alter pluggable database jypdb open; alter pluggable database jypdb open * ERROR at line 1: ORA-01113: file 45 needs media recovery ORA-01110: data file 45: '+DATA/JY/5F9AC6865E87549FE053AB828A0ADE94/DATAFILE/cs.294.966380783'
如是查询数据文件检查点SCN与数据文件头SCN，发现44与45号文件的数据文件检查点SCN与数据文件头SCN号不一致并且数据文件检查点SCN比数据文件头SCN号大，因此需要进行日志文件来进行恢复。但在执行recover datafile命令成功后，打开JYPDB时仍然提示需要进行介质恢复。
