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.

How to solve a dictionary access poor performance in 12C?

Jun 7, 2017 12:17PM edited Nov 7, 2018 12:24PM in SQL Performance (MOSC) 18 commentsAnswered ✓

Hi,

I'm having performance problems accessing the Oracle 12C data dictionary. - Oracle 12.1.0.2 EE with Oracle Linux 6.3.

Looking at metalink, I found solutions as below:

ALTER SYSTEM SET optimizer_features_enable = '11 .2.0.4 'SCOPE = BOTH;

This partially solved the problem.

Is there a patch or a different workaround?

Paulo
