Memory growth is observed by the propagation process; i.e the following query shows large memory allocations associated with PGA and UGA heaps ; memory continues to grow as propagation is ongoing :
select a.sid, a.statistic#, b.name, a.value
from v$sesstat a, v$statname b
where a.sid in (select /*+ rule */ sid from dba_jobs_running where
job in (select /*+ rule */ job from dba_jobs ))
and b.statistic# in (20,21,25,26)
and a.statistic# = b.statistic#;
The propagation job may then subsequently fail with the error :
ksedmp: internal or fatal error
ORA-00600: internal error code, arguments: [kwqpcbk179], , , , , , ,
