Effect of locked stats on dynamic statistics

edited Dec 8, 2018 9:51PM in Database Administration (MOSC) 3 commentsAnswered ✓

Hello All,

I was looking at any kind of repercussions as a result of locking schema statistics on other areas especially performance area..like dynamic statistics.

DB version : Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

I have referred 'usage notes' under LOCK_SCHEMA_STATS Procedure Parameters.

"This procedure either freezes the current set of the statistics or keeps the statistics empty (uncollected) to use dynamic statistics".

We have loading jobs in database frequently and i am worried if i will be missing the benefits of dynamic statistics due to locked statistics.I am locking the schema stats and scheduling stats gather job from scheduler as it has custom parameters for dbms_stats as per vendor requirement.

Howdy, Stranger!
