DETAILS OF INCIDENTS FIXED BY THE PATCH --------------------------------------- This patch fixes the following incidents: Patch ID: 7.2.0.100 * 3910095 (Tracking ID: 3757609) SYMPTOM: High CPU usage because of contention over ODM_IO_LOCK DESCRIPTION: While performing ODM IO, to update some of the ODM counters we take ODM_IO_LOCK which leads to contention from multiple of iodones trying to update these counters at the same time. This is results in high CPU usage. RESOLUTION: Code modified to remove the lock contention. * 3911964 (Tracking ID: 3907933) SYMPTOM: ODM module failed to load on SLES12 SP2. DESCRIPTION: Since SLES12 SP2 is new release therefore ODM module failed to load on it. RESOLUTION: Added ODM support for SLES12 SP2.
