Files are vanished in OEL 5.0
 

Hi,

I am using Oracle Enterprise Linux 5.0.This is same like RHEL distribution.Sometimes some files are missing.Some example files are *.exe, *.war.Can anyone let me know the solution? Please

How did they get lost? Removed? Examples just not installed? Does the vendor support its distribution? What does it have to say about it?

You would not expect to see .exe files in Linux. "exe" is an extension used for Windows executables. I don't know what a .war file is, and I have never seen one.

As unSpawn implies, you would need to tell us exactly what is missing (and what is not working).

Just an aside note: war files are java web archives. I've seen them when installing web applications using tomcat.

I have some important files in /tmp location.Now I cant see these files.I think I dont want to mention all those file names.These files are just documentation.Thats it.You can assume that some contents of /tmp folder are missing.

It may be the virus issue?

Nope. The /tmp directory is used by various applications to store temporary files. Temporary means they have not to be stored permanently, therefore there must be a mechanism to remove them periodically. Indeed most unix systems remove temporary files using a cron job, either by the find and rm command or by tmpwatch. In short the rule is: don't keep valuable data in the /tmp directory, since sooner or later they will be pushed in a black hole! ;)

If this is the case,will the Unix system remove the part of /tmp contents? Because I can see some old files which were created along with missing files.

Hi Colucix,

Is there any possible to find out cron job? If so,can you please let me know to delete that cron job?

In RHEL5 it should be controlled by /etc/cron.daily/tmpwatch which will be in turn managed by the system crontab - /etc/crontab - through the run-parts mechanism. See man run-parts and man tmpwatch for details, then you will find out the correct way to remove the cron job. But... I strongly suggest to not wipe it off, otherwise the /tmp directory (and its partition) can fill up in a short period of time. Simply, I would not keep valuable data in /tmp directory.
