Re: What is vnc
I must admit that being predominantly a mainframe user under z/OS, I also FTP download files to the PC, edit them and FTP upload them again IF I have a significant amount of rework on some code. Copy/paste and graphical screens (not fixed 43*80 screens used by ISPF-Edit) are just more friendly than ISPF-Edit on the mainframe. But for normal editing sessions, I still use ISPF-Edit.

Re: What is vnc
I use various NFS clients against Linux content all the time. One of interest is the CMS NFS client, which allows use of XEDIT on Linux files. Sweet! But be careful about dissing EMACS. It really is more than an editor. It's really a LISP engine disguised as an editor. (EMACS could be taught to speak 3270, if anyone took the time to train it on the UTSGlobal tube driver.) Actually, be careful dissing any editor because the whole thing tends to wax religious, as you've seen.

Re: hit ratio
Yes I agree your numbers are so low that this is of little consequence. The hit ratio means that when some user requested data it was found in the md cache so i/o was avoided. This is generally a good thing. Here's the explanation from the help: HIT RATIO-hhh% identifies the percentage of successful lookups in the minidisk cache. This is the percentage of eligible read I/Os that were avoided because of the minidisk cache. But your numbers this morning are so low no meaningful conclusions are valid.

Re: What is vnc
Greetings Warren. I've encountered times where I had NO choice but to use a GUI installer (Neon Shadow Direct Driver, for instance). When that happens, I would start a VNCserver. One comes with the SLES distribution. There are ones that have less overhead, but since I use this only rarely, I've not bothered. Starting the vncserver: vncserver -depth 24 -geometry 1024x768 :0 This creates a VNC server on which you can do something by connecting a vnc viewer to. You basically get an xterm shell and nothing else. No desktop overhead, no full blown KDE or GNOME. But it is enough* to use a GUI tool. Once you run this it wil prompt for a password to use to access things. It will also create a directory in your $HOME dir called .vnc - in that directory is a file called xstartup cat xstartup #!/bin/sh xrdb $HOME/.Xresources xsetroot -solid grey xterm -geometry 80x24+10+10 -ls -title $VNCDESKTOP Desktop twm The default seems to be to start twm - Tiny window Manager. It's ok. It works. it's ugly. You could choose to use another window manager as personal preference dictates. If you change this while the vncserver is running you need to stop and start it: vncserver -kill :0 - Where :0 is your X windows screen. Since there is no desktop running on z, :0 is available. On an intel box, you'd want to default to :1 or :2. Restart the server per above, and connect to the DNS resolveable name OR IP address using a PC based VNC viewer. Note: this is a great way to burn CPU resources on your z box. Get in, get done, get out.

Re: What is vnc
Another use for VNC has nothing to do with running it on the mainframe linux itself. You can run VNC on a smaller server and use it as a go-between allowing you to start long-running gui tasks (such as system installs) and then close your laptop and go home or to the coffee shop, where you can pick back up in your install without any loss or interruption. A second use, which we do here quite a bit, is the feature that a VNC session can be viewed by more than one user at a time (the -share option). This allows you to show a problem to a coworker or vendor, or to watch someone do a procedure and learn how to do it, or to share a desktop during a conference call. -- Bob Nix On 3/9/07 8:49 AM, James Melin [EMAIL PROTECTED] wrote: Greetings Warren.

Re: What is vnc
With the level of (pure) editing power that is out there in the world, I prefer not to use XEDIT anymore either. I also came from that environment which then turned into TSO/ISPF. The beginning of this last project has me using one of the 'pads' and I guess I'm spoiled. In fact, the vendor scripts I'm running convert input files because they expect you may be using a DOS editor. I do need to say that emacs actually does everything I ask of it but I did notice a spike in cpu usage when I'm editing a large text file. (In my case it was something close to 30-40% which seemed quite high since I was the only one the system. However this may be because I'm running Linux on a VM/Guest and I need to go beg the VM sysprog for a bigger slice...I don't know). This is another concern and makes me wonder if I need to offload this function to the linux desktops somehow. I think my main point is that I would like to use the power of the linux desktop to do the editing and use the VM/Linux guest as a file server. It sounds like NFS is made to order in this case. I'm a newbie so I'm bound to make some ignorant statements but I'm a good learner so I won't do it again [fo sho]. much thanks - Original Message From: Richard Troth [EMAIL PROTECTED] To: LINUX-390@VM.MARIST.EDU Sent: Friday, March 9, 2007 5:04:35 AM Subject: Re: What is vnc I use various NFS clients against Linux content all the time.

Re: Help with Virtual IP's.
No, you aren't missing anything. I was mistaken about the two OSA's in the same vswitch. I have two osas and two vswitches, and the two osas are on different networks, hence the need for ospfd and such. My original goal was to use the single vswitch with a failover osa, but as I pursued this problem I discovered from the network group that it wasn't configured the way I had originally thought.
