Warehousing and Quick Cached IO
Please excuse my ignorance but I have a question. We are currently looking
at using Veritas for our volume management and our file systems and are thinking
about using the Oracle Edition. We are in a warehousing enviroment. Unless
we have memory up the wazoo, I really don't think we will benefit in performance
in regards to Quick Cache I/O because potentially we could have literally
hundreds of datafiles. The only benefit I see would be the ability to have
the datafiles in a file system for management with an equivalent speed as
raw. Has anyone done any benchmarks in a DSS type environment. I have seen
them for OLTP but that does not do me any good.
Any thoughts would be appreciated,
Keith Janke
