As of this afternoon, version 126.96.36.199.1 of Oracle’s Exadata storage server software, is out in the wild. This is the first publicly available version of the 188.8.131.52 branch, a major release including a full OS image with an update to Oracle Enterprise Linux 5.5. A number of bugs causing cell server crashes and hangs have been fixed, including 9472035, 9870117, and 9722560.
Both storage server and database portions of this patch can be applied in a rolling fashion, avoiding entire database downtime. The minimum prerequisite version is 184.108.40.206.3, with an exception made for Exadata V1 devices at 220.127.116.11.0. If you’re running an earlier version, apply the 18.104.22.168.3 patch first.
