RE: Locking issue

I traced the row cache locks (event 10222, level 4) for both a select with dynamic sampling and the statistic job:

--select with dynamic sampling

SQL> !grep cid /u00/oracle/orabase/diag/rdbms/db_site1/DB/trace/DB_ora_15329_0001.trc | grep 'kqrpre:' | awk '{print $4}' | sort -u

cid=0
cid=10
cid=16
cid=2
cid=8

cid=0
cid=10
cid=11
cid=13
cid=16
cid=17
cid=2
cid=3
cid=61
cid=63
cid=8

Lok, you could try to capture the stack trace for the event 10222. Sayan has just published the article on how to do that: http://orasql.org/2021/05/20/oracle-diagnostic-events-cheat-sheet/

Best regards,
