ORA-01578: ORACLE data block corrupted (file # 5, block # 44)
ORA-01110: data file 5: '/home/app/oraten/oradata/oraten/logging01.dbf'
ORA-26040: Data block was loaded using the NOLOGGING option
数据库报错，看来恢复成功并不一定数据库就是正常的。
再看一下，日志的的dump内容，
[oraten@yue udump]$ strings oraten_ora_10509.trc | grep oad

看来日志中对nologging是有记录的，在rman恢复时，会根据记录将某些块设置为逻辑损坏。
