Okay,

#1 Rbattle

I am using P550 VIOS so it cannot have a dedicated SAN HBA card,

Have to first assign the HDISK from SAN to I/O VIOS server and then from VIOS to LPAR

#2 IBMTECH and Bakunin

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

AIX P4 = PRODUCTION
Code:
