Yes, both database size are exactly same, infact it is a clone of the production environment, the min max paging space and other parameters are also same.... everything is same. DATA, DATABASE, Parameters, OS,
only difference
ORADB = Production Environment runs on P4 and Oracle is on SAN = report take 25 minutes
CloneDB = Clone Environment runs on P5 and Oracle is on internal Disks = report takes 1 hour and 15 minutes
This way it sounds more logical, because SAN disks are (in most cases) much faster than physical disks. They have usually a lot more IOPS and more throughput bandwidth, because a lot of different reasons: stripesets, caching controllers, buses with higher bandwidth, ....
Your systems seem not to have the same amount of memory at all:
Further this looks dubious:
whereas:
Not the value in itself is problematic, but the huge difference. Monitor the value closely over time, if it increases heavily you have found a potential bottleneck. If it stays at this level it is perhaps an artefact of some temporary memory shortness.
Finally, the tuning parameters seem to be different (compare "maxperm" and "minperm" in the different outputs, probably others are different too). You should run "vmo -a" (and the other tuning utilities, "schedo", "ioo", "no") on both machines to investigate other differences. What good values for maxperm and minperm would be is hard to suggest because it depends heavily on the (detailed) OS version which we do not know.
Another supposition (which would have to be proven by facts) of mine is that the faster processor is not needed in the special kind of report you run and therefore contributes nothing to some faster execution, whereas the disks contribute heavily.
