[ale] Oracle Flash Cache on RHEL5 (or CentOS5 or any other variant except OEL5).

[Lightner, Jeff]

Oracle has a feature called Flash Cache that can be enabled in 11gR2.   It is apparently only officially supported in their knockoff of RHEL called OEL and also in Solaris.

We found a rather poorly written blog that seemed to suggest the user got it to work in RHEL but doesn’t give any details.  (It might also be read that he did NOT get it to work since he made a comment earlier about planning to move to OEL.)

I’m wondering if anyone has run into this and made it work on RHEL5 (CentOS5 or any other variant except OEL5).

P.S.  Surprise, surprise – Oracle started making OEL from RHEL source then bought Sun/Solaris and now seems to be doing its best to insure users are forced to use one of the two operating systems they own rather than allowing for open systems as they previously encouraged.   Not so long ago they announced they were not going to port new stuff to Itanium which effectively removes HP-UX as a choice.   They are making tools like this that they only support in OEL which effectively removes Linux competition if you want to use their DB and Apps.   Recently for another upgrade they suggested one use their OEL kernel in one’s RHEL box for “more features” but buried in their documentation they quietly note they won’t support that kernel unless one is paying them for a subscription and its certain RedHat won’t either since it isn’t them that supplied the kernel.   Nice Catch-22.

Apparently Oracle has learned much from Microsoft – better to force people into using your other products by removing interoperability than to actually allow choices.
