Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Explain plan - Index is causing issue

Feb 15, 2022 6:46PM in Database Administration (MOSC) 4 commentsAnswered

Hi Experts,

DB 12.2.0.1 April 2021 CPU. We have a simple select query which is taking about 9 seconds in prod and 0.2 seconds in non prod.

When we compare the explain plan seems in prod it uses INDEX but in non prod it goes for full table scan.

select count(*) from ps_combo_data_tbl where process_group = 'XXXXXX' and ACCOUNT = 'YYYYYY';

Prod:

Non Prod

Could you kindly suggest?
