Or TELNET 127.0.0.1 to get to the "localhost"? That's what I do, on
occassion, on Linux.

I am not sure what you are trying to do but you might try using
telnet.
From your logged on CMS just telnet xxx.xxx.xxx.xxx < == your
z/VM systems IP.
This should allow you to logon to something else, without
killing your old logon.

Re: switch user without logoff
Always give hard problems to the laziest man you know. They'll find the least difficult way to solve the problem. I think it would be more lazier if i just do all the thing how i learned, without thinking how can i make things better, easier and safer.

Oh yes. If you TELNET you get to the VM logon screen and there you can issue the logon xxx BY xxx. Using PASSTHRU or SESSION from your CMS userid was popular when we had physical terminals with limited number of sessions or when there is limited connectivity to the target system. And for the MVS people it was often a VTAM application playing (multi) session manager. A special "temporary disconnect" allows you to go back and forth while keeping the target session open in the background. The biggest drawback is that you tie up the CMS session when you reach out to the other target session. Most folks today have a workstation with a TN3270 client. In that case it is much easier to just open a new session on the workstation and navigate between the sessions. Some of the analogies just don't do it when you try to find "a way to do it on VM" and it helps to understand what function you really need. As others suggested with TRACK, you don't have to logon to the userid to see (part of) console output. Also, many applications keep log files on disk where you can see them, or you may need to close the spooled console to see things. Quite often we find it easier to review log files to see what happened rather than "try it again while we're looking at it" I find the "SEND" very effective in doing things for other virtual machines (either with or without SCIF). If you make PROP the secondary console for your service machines you have central logging plus the ability to issue commands without leaving your place. Rob

Always give hard problems to the laziest man you know. They'll find the least difficult way to solve the problem. Look around for a copy of RXLDEV. RXLDEV is a REXX function package that allows you to create and manipulate CP LDEVs from REXX. Once you can do that, you can automate just about anything. If all you need is to issue some line-mode commands and trap the output, don't forget that telnet can be simulated in REXX by using RXSOCKET calls connecting to port 23. Two other must-have tools: SESSION has already been mentioned, and if you have a privileged ID, you must have a copy of TRACK. I carry them on a USB drive everywhere I go.

You can create arbitrary numbers of sessions (I typically have 8-10 defined) and switch between them with a PF key or by name. Each session does need to be a separate userid, though; nothing equivalent to 'su' within the same session. YVETTE's got some more sophisticated features, but SESSION requires zero installation and configuration; copy the binary someplace convenient, SESSION FOO PF12, and you're off. Hit PF12 (or whatever you defined the exit key to be), and you're back to the original session. You can even run SESSION from inside XEDIT if you need to pop over to another id and check something out and come right back to where you left off.
Re: switch user without logoff
Okay, so how I read your problem is that you have some process running in another virtual machine and you want to check it without logging off your id and logging onto the other id. There are several ways and I sometimes use all of them. First, spool the console of the process virtual machine, write status messages to that virtual console, get the TRACK program to view the current open console buffer. Or get the VM:Spool product from CA and use it to view the entire console log. Another way is to write those status messages to a file on a minidisk and use "VMLINK processid cuu ( FILELIST" to look at the current read-only view of the status file. An older style of sending status messages is to at regular intervals, send a punch file with a status message in it to your monitoring userid, and user RDRLIST/PEEK to view the status messages. There are more advanced techniques like including an SMSG/IUCV handler into your process virtual machine to intercept, parse and respond to queries for status messages. /Tom Kern /301-903-2211 --- Zoltan Balogh <[EMAIL PROTECTED]> wrote: > First of all, if i forget: Happy new Year, happy 2007! > > ...snipped... > Nowadays i finished all change what i could do for make things easier, but i > was thinking of maybe possible to do the checking phase (using two user with > method logon by) without have to logon manually to each user.

Since I connect to VM with some flavour of TN3270E, I usually just open another session, that way I can have both VM sessions visible at once. The "session" command allows me to flip back and forth between two IDs with a PF key, but there's nothing like having both visible at the same time. However, I use "session" more and more to log on quickly for a specific task because the method we have to use to get logged on is getting more and more inconvenient in the name of security.

Re: switch user without logoff
Not sure what you are after, but maybe #CP DISC HOLD will help? To me, it is a lot like the "switch user" feature of some Unix/Linux X session managers and of Windows (XP) home edition. If you're connected via VTAM, your "session" usually remains. If you're connected via TELNET, your "session" usually drops when you DISConnect or LOGOFF. But the HOLD option retains the connection. Very handy. Conceptually like a "switch user" function. I second Mike Walter's endorsement of SESSION. -- R;
Re: switch user without logoff
First of all, if i forget: Happy new Year, happy 2007! Tell the truth i had many problem about posting this problem to list because SMTP server didnt want to follow in 2006. At least for one week when ive got a new message what isnt contained: it just a warning message, you dont have to resend your email. Then i tried again, and that time i was lucky. So it is just a simple story about the source message, and what i wanted to say yet: i always very happy i got many help and ideas how can i solve my problems. So a very big thank you for you all! Ok, back to the questions. Sorry i start with a little story too for getting picture a bit more about my line of my questions. Im working at IBM, ive got this job in end of september, about 3 month after i got my degree. I knew ill work with mainframes, with VM. Ive got basic and advanced level knowledges of VM using and administrating. Now me and one of my collegue got a project what is started to migrating to our country some month ago, almost the time when i joined. Nowadays i have to check logs and files and -tell the truth- ive got many free time. So i started to make some rexx & pipe prog for my fun (see: questions about using colors) and i tried to make the checking phase a bit more easier if i can (see: problems with starting exec's from an exec). Nowadays i finished all change what i could do for make things easier, but i was thinking of maybe possible to do the checking phase (using two user with method logon by) without have to logon manually to each user. I know it is a very lazy thing, but while im trying to solve problems i know more the VM and ill see more its borders, what can i do and what not. And if i can do it, how. So this is the answer to your question, what do i want to do ( and a some kind of why in my long story) Zoltan Ps: Ill give a try the telnet, perhaps the "users" have right for using telnet. (the logins i log into are seems only for checking and maintaining, if i good well they arent kind of service machines, or maybe only at night)
Re: switch user without logoff
One "Sessions" was a freebie "value add" from Amdahl for their customers. Great stuff. Instead of logging on, you issued a DIAL PIE (or whatever server name you used) command and it permitted starting up and hot-switching up to 12 logons from that single screen. Didn't Arty Ecock had another program named "session" that built an LDEV on an existing logged on CMS userid, and popped you into that session? The old Amdahl Sessions tool was bought by Technologic Software Concepts or Irvine, CA. They renamed it Pie/VM-Sessions, enhanced and supported it for many years before their direction changed. They formally dropped the product and its support on January 1, 2000 (killed by Y2K; with few customers they did not want to spend time re-writing the code to validate the CPU serial number against the 4-digit date). But PC terminal emulation software has pretty much made it obsolete anyway, although with an added cost of a communications connection for every emulator session. With TCPIP, the cost of the connections is pretty insignificant - SNA was a little more expensive. None of those were anything like Linux's sudo. If the requirements were made clearer, perhaps we could address it another way (maybe using SCIF, or a server running a command authorization program).

No, there is no built-in "hot key" function in CP maintain multiple terminal sessions on a single (real or logical) connection. I suggest one of the following (in order of preference): 1. Create another emulator session to connect to VM and use your emulator's own "jump next" key to switch between sessions. 2. If you are connected to a 3270 terminal controller (e.g. 3174), use the Multiple Logical Terminal (MLT) function of the controller to perform the switch function. 3. Download the YVETTE package from the VM Download Library. You can program a PF/PA key to act as the "jump next" key. Alan Altmark z/VM Development IBM Endicott
