You don't need to "find" it. Oracle will tell you when it discovers a deadlock!

When it does it'll raise an ORA-00060. And write this to the alert log, e.g.:

ORA-00060: Deadlock detected. More info in file /ade/b/573371012/oracle/log/diag/rdbms/b11204n/b11204n/trace/b11204n_ora_24107_CHRIS.trc.


The tracefile will give you more information about the sessions and SQL involved. For more info on reading this, see:
