Uncovering Oracle’s Hidden Parse Failures: Why AWR Shows 99% Parse Time

A customer’s Oracle 11g RAC experienced chronic high CPU usage; deep AWR analysis revealed that massive parse time was attributed to mutex waits and a hidden hard‑parse failure caused by a missing column, which triggered Bug 16175381 and forced process spin, ultimately resolved by correcting the faulty SQL.

MySQL Time Zone Setting Causes High CPU and Slow Queries Due to Mutex Contention

A production MySQL incident showed sudden system CPU spikes and many running threads despite low query throughput, which was traced to the server's time_zone=system setting causing timestamp conversion to lock a global mutex, leading to excessive spin‑locks, context switches, and degraded performance that was resolved by changing the time_zone to a fixed offset.
