Thats the output of: fuser -c <filesystem> Its very handy for finding process with open filehandle in a specified filesystem.

The output you see are indeed process ids the format of the output is pid status(user) so given the above output

19570o(oracle)   10884o(oracle)    5627c(root)   25359o(oracle)

o - open files
c- current directory

check the man page for more info..
