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

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
