One of the major vehicle drivers for SAME is the convenience of management. It hands down a great deal of the performance factors to consider to the OS and also the underlying storage space layer. The suggestion is that your tablespace documents are currently spread out throughout a zillion disks in the storage space array so any kind of messing around you do in addition to this does not aid a lot. Nonetheless, as ever before, the evil one remains in the information. It is alluring to deal with the storage space layer as a black box yet you actually do require to recognize what is taking place and also recognize what rests under each of your tablespace documents.

From a do not - desire - to - touch - the - config POV - examine your indexes. if you are contacting tables that are greatly indexed, bear in mind that each time you write a row, the indexes are being transformed. Less indexes, much less physical IO.

This will certainly - clearly - have an influence on reviews.

If you have the moment & ability, I have actually located dividing generally created tables right into details tablespaces and also seeing to it that/those tablespaces are saved on a different RAID network additionally aids, yet this relies on the hardware you are making use of and also includes a number of various other factors to consider.

If you actually do have time to contemplate this, after that acquire & read Cary Millsaps 'Optimizing Oracle Performance' - it's dated (all relying on what variation of oracle you are making use of) yet a timeless.
