Symptoms

session hang during insert with parallel dml

From the Hang Analyze found that same ISNERT is running from sessions and one session is blocking by other.

 

On further investigation found that issue is due to the Unified auditing on.

PARAMETER            VALUE

With unified auditing off and audit trail is set to "DB,extended" the query is running very fast.
