203
what are MEANT to do ...
204
1) extract candidate SQL statements
2) consider candidate indexes per SQL
3) consolidate overlaps
4) create invisible/unusable
5) check "virtual" explain plan
203
204

92. 16/10/2019
92
205
6) create true index (as invisible)
7) test execute each SQL for benefit
8) decide on index benefit for each SQL
9) SPM to avoid regressions
10) make new indexes visible
206
every
