>The z890 that was loaned to ISU will be configured as a model 370 and with an IFL. It will be configured with 4 LPARS. A z/OS LPAR will be for operating system students to install, configure and IPL at will. I can only imagine how many times that will be IPL'ed in a day. The other LPAR will be a more stable z/OS system for teaching DB2, COBOL, Assembler, and other courses. I heard at Educause that a large retail company has donated 2 million rows of transactional DB2 data for the Academic Initiative project. There will also be two z/VM LPARS with Linux instances under them. > If the idea is to be haveing students IPL the z/OS partition many times a day, I do have a suggestion and I must warn you, I was a MVT/MVS/TSO bigot for a time until I was in an installation where I needed to something similiar. My direction is to put z/VM in the LPAR for z/OS IPL'ing and you can have as many students working at one time, versus single threading them through the computer room at the HMC. I had an LPAR which needed to support my VM/XA system and my bosses MVS/XA system for testing. After I getting it in the morning and the rest of the shop got it in the afternoon, I finally IPL'ed a VM/XA Hypervisor bare-bones system and IPL'ed my VM/XA test system 2nd level and his MVS/XA system 2nd level. He worked on his system most of the afternoon and saw me working on mine and was very puzzled. He asked my how and all I said was, "You are my Guest" and he knew, blew up and threatened to fire me. He was a civilian and I was military. He crashed all systems and was furious. About 3 days later it dawned on him the value and I showed him how he could IPL his system from his desk, etc. To do what you have to do is quite easy and since you have z/VM expertise, it should very, very, simple. Besides the DASD savings can be enormous. I would define for my trainee, a 15 3390 system which was only actually using 5 3390- 3 volumes (3 mini-disk volumes per real volume). So to my trainee, it looked like he had 15 actual volumes to make it seem more world like. Then they could ipl it from their desk, etc. So they had to learn how to build the system, cutomize everything from PARMLIB to JES2 to VTAM to etc. AND if they hosed things up, it would not harm anything. Think about it. I know IBM understands the value of z/VM for their training classes are most always hosted as z/OS guests of z/VM. jim ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
