Query to return all Oracle Deadlocks in 12c












2















Is there an object I can query in 12c to return all ORA-60 Deadlock alerts?



I just want to do a weekly report that outputs the number of deadlocks that have occurred and what schema they occurred on.



My Oracle knowledge is not great, and I have drawn a blank when searching for resources on this online.



Thanks

          Sure:



          select
          ss.value
          from
          v$sysstat ss
          join v$statname sn using (statistic#)
          where
          sn.name = 'enqueue deadlocks'
          ;


          I did not test it extensively though.

          • @Molenpad It is the number of deadlocks since instance startup. I am not aware of any semi-reliable method that gives this information by schemas other than analyzing all the trace files created on deadlock occurences.

          The deadlocks are reported to the alert log with the error ora-00060 if I remember well, and with X$DBGALERTEXT you should be able to "query" the alert log, based on that you should be able to create a query where you can get the deadlocks occurred during some window (days, weeks, etc) as long as you have the info in the alert log.
