ORA-01194: 文件 1 需要更多的恢复来保持一致性 解析
ORA-1194 "file %s needs more recovery to be consistent" ORA-1547 "warning: RECOVER succeeded but OPEN RESETLOGS would get error below" ORA-1110 "data file %s: '%s'" ? [oracle@mlab2 ~]$ oerr ora 1194 01194, 00000, "file %s needs more recovery to be consistent" // *Cause: An incomplete recovery session was started, but an insufficient // number of logs were applied to make the file consistent. The // reported file was not closed cleanly when it was last opened by // the database. It must be recovered to a time when it was not being // updated. The most likely cause of this error is forgetting to // restore the file from a backup before doing incomplete recovery. // *Action: Either apply more logs until the file is consistent or restore // the file from an older backup and repeat recovery. [oracle@mlab2 ~]$ oerr ora 1547 01547, 00000, "warning: RECOVER succeeded but OPEN RESETLOGS would get error below" // *Cause: Media recovery with one of the incomplete recovery options ended // without error. However, if the ALTER DATABASE OPEN RESETLOGS command // were attempted now, it would fail with the specified error. // The most likely cause of this error is forgetting to restore one or // more datafiles from a sufficiently old backup before executing the // incomplete recovery. // *Action: Rerun the incomplete media recovery using different datafile // backups, a different control file, or different stop criteria. [oracle@mlab2 ~]$ oerr ora 1110 01110, 00000, "data file %s: '%s'" // *Cause: Reporting file name for details of another error. The reported // name can be of the old file if a data file move operation is // in progress. // *Action: See associated error message.
ORA-01194: 文件1需要更多的恢复来保持一致性
ORA-01194: file 1 needs more recovery to be consistent
假设所有的oracle数据文件均成功restore并recovery，但打开数据库时仍报错，那么
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: ‘/system01.dbf’
