Oracle announced a new Exadata Critical Issue this morning (EX21) which applies to the ESS software versions 18.104.22.168.2 and 22.214.171.124.1.
“This issue is encountered only when a disk media error occurs while synchronous I/O is performed. Because the majority of I/O operations issued with Exadata storage are done asynchronously, and this problem is possible only when disk media errors are experienced while synchronous I/O is performed, the likelihood of experiencing this problem is low. However, the impact of hitting this problem can potentially be high.
This problem affects Exadata Storage Server software versions 126.96.36.199.1 and 188.8.131.52.2.
Disk corruption symptoms are varied. Some corruptions will be resolved automatically by Oracle Database, while other corruptions will lead to unexpected process shutdown due to internal errors.”
ESS 184.108.40.206.1 DOES have a patch available, but 220.127.116.11.1 does not at the moment (the patch is “pending”). I’m sure it will become available soon.
I have MOS email me whenever the Exadata Critical Issues document (1270094.1) is updated so I’m quickly aware of the latest important bugs. It’s pretty neat and I’d advise other Exadata types to make use of it as well.
