Hi,
I am an oracle DBA pretty new to unix. We had one of the filesystems full and a colleague cleared some stuffs to create more space. I just checked now and found there is now more space available. How do i find exactly what he cleared? We have oracle database installed and its a RAC environment. I set environment to one of the instance and checked the path for our ORA_ALERT doing:

tail **full path**/bdump/alert_BC2.log

After i did this, i didnt really find anything similar to what he did. Can someone please help?

Hi,

did your colleague made space-cleaning via Oracle (i.e. by shrinking datafiles, removing old RMAN backups, etc.) or did he operated via operating system commands (i.e. deleting filesystem files, etc.)?

I am not sure. What i think is he either removed some old logs or deleted maybe a core file or probabaly searched for any large file in that directory.

ok so, if he made the search and removal job via command line there is a chance his commands are still recorded into the history file.
if you share the same operating system login account on the machine you could try with a

history | more

ls -laR | more

Thanks Frappa. We share the same login and checking history as you said was helpful. Thanks for your help
