Another Support Case Study : OCFS O_DIRECT flag, file system cache and RAC consistency among SGAs

Filed under: Oracle How To — H.Tonguç Yılmaz @ 8:05 am

Knowledge comes with experience and experimentation, but of course only your experiences will be limited. Other than documentation I love reading support case studies very much. They are real life experiences, you can also find out some “don’t do”s and bugs here.

So I want to share one recent Ubtools support case study I liked very much;

“ORA-01187: cannot read from file” in one of the RAC Node

And two complementary reminders;

Ubtools support issuenavigator and RSS

Previously released Oracle support case studies
