(Oops. This reply went to the wrong thread.) We have never defined any installation userids on any SE. The only users defined are the standard IBM supplied one. Are you saying, if we defined at least a few of our own, we could have multiple 'sysprogs' logged on simultaneously?

Sent: Thursday, May 28, 2020 9:25 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: (External):Re: HMC in Service Mode, IPL Question CAUTION EXTERNAL EMAIL I think you mean user like SooSysprog. Soo means Single Object Operations. This is complex issue, and it is fixed in 2.15 (z15 machines) - I know that from guy who is part of HMC/SE development team. Regarding z14 and older HMC levels the devil is in user table. 1. Some people do not define users and use pre-defined one like SYSPROG, OPER, SERVICE, etc. Sometimes even with default passwords. ;-) It's not worth further investigation. 2. Some people use LDAP, let's ignore it for clarity. 3. Some people do define custom userids, preferably each person has its own userid. However there is some "gotcha" here. You define users in HMC. HMC, but not SE. SE has still its own, predefined set of users. What happens when user JOHN1 defined as clone of SYSPROG logs on HMC? He is JOHN1. What about single object operations? Well, SE doesn not know JOHN1. However SE knows and trust HMC. In that case JOHN1 will be mapped to SooSYSPROG, which is SYSPROG equivalent. So, JOHN1 may manage SE. My recommendation is to repeat user definition on each SE and HMC in your shop. Of course there is no requirement all users have to be equally defined. However the above ...has no meaning for your issue. Why? Because of locked resource. SE object is busy and that's why any other person cannot perform SOO. The same apply for for many other objects in SE and HMC. Regarding Service Mode - I see no cons against IPL during this time. Note, IPL has very little to do with SE. Yes, SE initiate IPL process, but it is very limited. -- Radoslaw Skorupka Lodz, Poland W dniu 28.05.2020 o 17:33, Jesse 1 Robinson pisze: > We have remote access to HMC/SE.
