For those how are interested in what I am doing now I provided my app screenshots with ‘Find Peaks’ button that runs ZScore algorithm on a cryptocurrency market data (follow the this link for the algorithm source code in C++).
Honestly I am not quite enough understand yet how it works, because I run it first time today, but at least there is some correlation between input parameters and the results. The lesser the threshold and the longer the lag the lesser peaks are found. Increasing the influence also reduces the peak count.
I succeeded with building my app for iOS and my first step in publishing the app in App Store was opening generated .xcodeproj file in XCode, but XCode froze displaying rotating progress indicator and wait cursor.
SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Unified Auditing';
Check what options are enabled:
SELECT up.AUDIT_OPTION, uep.SUCCESS, uep.FAILURE from AUDIT_UNIFIED_ENABLED_POLICIES uep, AUDIT_UNIFIED_POLICIES up
where uep.ENTITY_NAME = 'ALL USERS' and uep.ENABLED_OPTION='BY USER' and uep.POLICY_NAME = up.POLICY_NAME and up.AUDIT_OPTION_TYPE = 'STANDARD ACTION'
