RMAN uses v$session_longops to record it's progress. After each backup set
it uses the DBMS package to update "progress" in the V$ view, having first
queried out of the view to find some relevant data within . So when the view
goes "bad" RMAN does its initial backup set/piece, trys to update
v$session_longops and subsequently gets an Ora-03113
error and dies. Hence,
the backup "fails" inasmuch as it did not run to completion. I reality we
get less than 10% of our Db backed-up when this problem is in force.
The query RMAN runs (and gets ora-03113
select sofar, context from v$session_longops where sid = (select distinct
sid from v$mystat) and opname like 'RMAN:%' order by start_time desc,
Hope this is clear
