Finding what tables are in INMEMORY

by Granville Bonyata on March 26, 2017

Since INMEMORY allows the INEMOMERY and its compression settings to be at the column level, when looking at what we have INMEMORY, besides v$im_segments, we need to also look at V_$IM_COLUMN_LEVEL.

When checking for INMEMORY, I look at:


dba_tables – Is the table configured for INMEMORY.

v$im_segments – Has the table actually been loaded into INMEMORY, and if so, is it completely loaded so it can be used?

v_$im_column_level – Which of the columns are INMEMORY?
