Very good point. The "effort to handle raw" is nothing less nothing more than a modern myth. In the bad old days before Logical Volume Managers, indeed it was a pain to partition a disk into raw sections. But this has not been the case now for over ten years. Even without LVMs, some makers had other very good tools to achieve this. Pyramid for example had a tabular partitioning text config file that was dirt easy to manage with an editor.

With LVMs, the thing is so dumb easy it is now probably a lot more complex to lay a cooked file system on top of a raw partition than to just give it to Oracle and be done with it. However, the snag remains that a raw partition has to be totally given to Oracle. While a file system may be shared with other non-Oracle data. This can be an advantage or a disadvantage, contingent on how the system is being used. Received on Thu Sep 16 2004 - 07:33:07 CDT
