hi all,The minimum storage space required for the selected physical design structures exceeds the default storage space selected by Database Engine Tuning Advisor. Either keep fewer physical design structures, or increase the default storage space to be larger than at least 3 MB.Use one of the following methods to increase storage space: (1) If you are using the graphical user interface, enter the required value for Define max. space for recommendations (MB) in the Advanced Options of the Tuning Options tabbed page; (2) If you are using dta.exe, specify the maximum space value for the -B argument; (3) If you are using an XML input file, specify the maximum space value for the <StorageBoundInMB> element under <TuningOptions>I set max space for recommendation in tuning option, but not affect!
