A question on execution plan

edited Nov 25, 2014 1:51PM in Database Tuning (MOSC) 5 commentsAnswered ✓

Hi experts,

I am on Oracle 11.2.0.4 on Linux. I have following query plan (a part of the big plan I have copied here) for one of the sql and have a question about it.  It shows some big numbers under OMEM/1MEM/USED-MEM  sections of the runtime execution plan. What does it imply? Does it mean that the query has an issue? The query completes in less than 10 seconds which is acceptable but i am not sure of the memory related issues and need help on it: The output is from this command and I didn't want to reveal the actual table

Howdy, Stranger!
