We are looking at doing some encryption on our z10 usings ICSF and the supplied CPACF faciltiy that comes with the z10. This encryption will be done using DB2 v9.1 and OS 1.11. Is anyone doing this and what impacts have you seen on CPU usage. IBM tells us it depends on what you encrypt no big suprise but we are doing hospital and doctors claims so we have HIPPA requirements to encrypt some dat fields but not entire records. So if you are doing this any help in deteriming impacts would be help full. We plan on starting testing to give us some idea of the impact in September but would like to know projects before hand.
