Hi,

The tail of my log is the following:

# tail LOG.033010
...
**INFO** Time: 19:36:15 Operations: STOP DATABASE SYSTEM initiated.
**INFO** Time: 19:36:20 Operations: STOP DATABASE SYSTEM completed successfully.
**INFO** Time: 19:46:38 Operations: START DATABASE SYSTEM initiated.
**INFO** Time: 19:46:50 Operations: START DATABASE SYSTEM completed successfully.

BUT

# ls -l log
-rw-rw---- 1 xxx xxx 77431 Mar 30 18:38 LOG.033010


So, how is it possible that some process writes to the file but file time modification still remains untouched?

Thank you

is the time off on the machine writing to the file?

I don't know how linux handles it, but two guesses are

1: The database has an internal clock adjusted so that it is a constant and doesnt change when the clocks do.

2: The amended date/time of a file is only done when the file is closed or a specific type of write is issued, so while some buffered writes (from the cache) show up in tail the OS hasnt amended the time because the file never closed or there are oustanding cache writes pending (this would be my guess otherwise the OS would be doing nothing but updating the last changed time on a quickly changing file) perhaps its an option of the FS on the disk?
