Radoslaw. OK, you made me go look at the IMAGE profiles for my PROD systems. We have 3 PROD systems on a single CPC. My recollection was incorrect, and should have looked before I replied. We have 3 domains, one for each prod lpar assigned USAGE on each, with 4 crypto engines online. All 3 prod lpars have Control access to all 3 domains, and was the source of my mis-information and are set that way, so that when we do TKE key ceremony, we can load the PROD master keys for all PROD domains in one operation.
My apologies for spreading FAKE NEWS. :) -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of R.S.

Our PROD lpars are all on the same domain. IMHO no, domains cannot be shared. Maybe your prod LPARs reside on different CPC each? Some remarks: 1. Single LPAR can have more than one domain, but z/OS ICSF can use only one at a time. However you can change domain number in PARMLIB and recycle ICSF. 2. Domain number cannot be assigned to more than one active LPAR. Deactivated LPARs could share domain id. 3. In the old days it was possible to have i.e. 40 LPARs and number of domains was 16. In that case More crypto engines were needed, for example Crypto 1 and 3 were assigned to LPARs 01-0F, Crypto engines 2 and 4 were assigned to LPARs 10-1F and remaining LPARs had no access to Crypto engines (CPACF is not affected). In that case LPAR 01 and LPAR 11 may have Domain Id 2 assigned, but on separated Crypto engines. 4. It is impossible to have i.e. Domain 12 on Crypto1 and Domain 07 on Crypto2 at a time. 5. It is also possible to have the same master keys on different domains (and even different CPCs) - in that case, CKDS/PKDS can be shared/copied between that systems. -- Radoslaw Skorupka Lodz, Poland ====================================================================== Jeśli nie jesteś adresatem tej wiadomości: - powiadom nas o tym w mailu zwrotnym (dziękujemy!), - usuń trwale tę wiadomość (i wszystkie kopie, które wydrukowałeś lub zapisałeś na dysku).
