- Hi. I am working on an application that needs to be able to guarantee
- that certain data has become "permanent." It has been proposed that this data
- be written to a database table during the interval it needs to have that
- status, but it seems to me that's somewhat excessive. I would like to be
- able to write the data to disk using the O_SYNC flag to open the disk file.
-
- I am under the understanding that due to the nature of the AIX filesystem,
- it is guaranteed not to become corrupted or to lose files under any
- circumstances short of physical damage to the disk. What I would like to
- know is whether the same that is (allegedly) true of filesystem structure
- is also true of file data.
-
- In short, once I know that data has been written to the disk, can I be sure
- that it is just as safely there as if it had been written to a commercial
- database table?
-
- If someone can give an authoritative answer I'd be most grateful.
- Thanks,
- - Jeff.
