Significant 'Cursor: Pin S Wait On X' Waits When Using In-memory Column Store and Parallel Query (Do

edited May 6, 2022 8:30AM in Database Tuning (MOSC) 8 commentsAnswered ✓

Hello everyone,

I am enabling IM for several tables and for some queries that access tables with parallel IM I found a downgrade due to 'Cursor: Pin S Wait On X' Waits .

It looks like situation described in Doc ID 1910787.1

But I am on Oracle version 19.10 , 2 nodes RAC , EE , ( OS Red Hat Enterprise Linux 7.9) and document states that the problem is fixed in 12.2

Does anyone have the same problem ?

Do you have suggestion on how to fix it ?

Thank you,

Paolo Castelletti
