z/os db2 what datasets do i need from smpe for db2 to run?

at this organization, after the smpe work was done, the following datasets were moved from the smpe environment to the db2 environment. then db2 was taken down and all the datasets were renamed. this seems like way to many datasets to me. how many of these datasets are really needed?
