Do statistics impact insert into global temporary tables?

edited Aug 31, 2018 5:02AM in Database Tuning (MOSC) 8 commentsAnswered

On 12c with GLOBAL_TEMP_TABLE_STATS set to SESSION, experiencing performance problems with the insert into global temp tables.  The insert completes sometimes and sometimes hangs until killed.

Can anyone shed light on how statistics may or may not be impacting this?

Howdy, Stranger!
