Re: Novell Suse vs Red Hat
We chose SuSE originally based on license/maintenance costs. (Our management demands contracted support.) We later switched to RedHat since Oracle supports running on RedHat but not on SuSE. Since we only want to support one distro, we went with RedHat.

Re: db2 scripts using crontab
Crontrab runs a minimal profile before it executes the command. You man need to run the root profile within your script. Use the .

Re: newbie : can i resize an ext3 fs
Assuming you are running under z/VM: If you have all file systems on the same disk you may want to move one or more directories to their own physical disk. You can use the command du -sk * to get the current size of the files in a directory and its subdirectories. Create a disk of a size that includes room for files and growth, copy the files from the directory to the new disk, mount the new disk at that directory, and erase the old files. (You may need to perform the erasure from another Linux instance. See below.) Modify /etc/fstab so the new disk gets automatically mounted. Directories that are most often split off are /tmp, /usr, /var, and /home. The idea is to keep those file systems that most often fill up from affecting the root ( / ) file system. After you mount the new file system you will not have any extra free space. The old files are still under the mounted file system taking up space. Shut down the problem operating system. Detach the problem disk (or log off). From another Linux instance link to that disk. Mount it at /mnt. Erase all the files and subdirectories under /mnt/var/. Umount the disk and detach it. Log on to the problem system and boot. Your world should be bright and sunny! Some file systems cannot be split from root ( / ). They are needed before the other file systems get mounted. An example is /etc. If this all seems overwhelming, you can just DDR your current disk to a bigger disk, swap the disk virtual addresses, and boot from the new disk. There is a resize2fs command so that will expand the file system so it can use the new space. Others who know more can expand on these notes.

It works better if most of those noework connections are between virtual machines on the same mainframe. Those connections are virtual and data moves at the speed of memory. There are other pipes to move data between mainframes. There are channel-to-channel adapters (fiber) and such-like.

(There may also be LIFO pipes, but I am not sure.) It is a staging device of a sort. Application 1 will write to the pipe when it is ready. Application 2 will read the data at its leisure. When FTP tries to read the pipe it waits for some other application to write to the pipe. Unless some other application writes an end-of-file to the pipe, FTP will never end. Don't try to FTP it. Application 1 on the new system may build the pipe there. If not, you can manually build it.

At point d we look at the system and see the first space partially full and the second with some pages being used.

It appeared the commands worked because they created the log files (with correct date and time stamps) associated with the maintenance. But on closer examination the files all had a zero byte count. So it looks as if crontab is doing his job and maintenance is starting but no output is coming out and it also looks as if the backups aren't done.I did a chmod on the scripts so I know they can be executed.

Do you use the SUSE provided s390tools or a selfcompiled version?
To catch most of the possible reasons:
Can you post the output of
- uname -a
- strace vmcp q userid
- stat /dev/vmcp
- cat /sys/class/misc/vmcp/dev
- rpm -qv s390-tools
- which vmcp
- file /usr/bin/vmcp

On my SLES 9 Lin-z system on zVM 5.2 I have a recursive directory loop. It is at /var/lib/ntp/var/lib/ntp/ The bottom ntp directory is actually a link ntp -> ../.. I guess it is just a way to keep system programmers busy! :-) Since I don't need ntp on my Lin-z/VM system I guess it doesn't matter. Has anyone else seen this?

Re: Dumping a LIN-z System
Thank you!
We have decided to go with VMDUMP rather than disk-based dumps. I will try
making vmhalt=VMDUMP. The "Dump Tools" book seems to be for the October
2005 stream, but I read it anyway. It did help.
Thanks again!

You're right that one dump disk per server does not scale, and picking
one from a pool is not trivial (well, a pool of 1 could do). But you
would be better off with VMDUMP instead.
If the kernel crashes the CP READ wil make evidence disappear before
you're there to take the dump. My understanding is that the kernel
does a halt in case of bad damage, in that case vmhalt="VMDUMP 0:ALL"
would do the trick. Have a look at the "Using the dump tools" book
which describes the process to read in the dump in Linux (in the Linux
that caused the dump, or at least one with exactly the same level of
kernel).

Dumping a LIN-z System
It looks to me that taking a dump of a LIN-z system is a manual process. You either manually IPL a disk, a tape, or you do the VMDUMP command. The automatic dumping after an oops or kernel panic that is available on LINTEL is not available on LIN-z. True? It seems that if I don't want to have a dump disk on every LIN-z system then I need to do the VMDUMP. Could I have a pool of dump disks and link to one when I need it?

How to load the vmcp driver?
I am playing with VMCP. It uses a driver named vmcp.ko that appears as /dev/vmcp. In order for this to work the driver must be loaded. It can be done manually with modprobe or insmod.

It seems to me that there must be a better way to have a driver loaded at boot time. Isn't there a file that has a list of such things? modprobe.conf.local just has alias names and options.

You've gotten some good responses. Does this information help? Linux is a done-by-volunteers implementation of POSIX. Unix is a branded implementation of POSIX (and contains "DNA", as they call it, of the historical Unix operating system). As far as we know, Linux does not contain any AT&T Unix code. Unix (POSIX) implementations that run on mainframe hardware include: + UTS (originally from Amdahl, now spun off to UTSGlobal) - AIX/370 (including both S/370 and XA operation modes) - AIX/ESA .. way ahead of its time! - "experimental" systems such as IX/370 and VM/IX * USS * OpenVM + Linux The last two, marked with "*", are not stand alone operating systems. The two marked with "+" are the only currently viable POSIX operating systems available for mainframe hardware. UTS is the system on which I learned Unix. It has always exploited S/370 (and now S/390 and zSeries) hardware, not merely tolerating it. For example, UTS treats 3270 terminals as normal terminals and addresses the EBCDIC matter and the block mode nature of these devices in some creative ways. I have heard it said that the original developers of UTS not only understood mainframe hardware but also understood Unix. (This is counter to the usual "us -vs- them" embattlement between mainframe people and Unix people.) AIX/ESA deserves mention for its academic and historical value. It had a Mach based kernel, a feature which makes it superior to Linux. It exploited S/390 "data spaces" rendering enormous memory regions, beyond its contemporary Unix peers. AIX/370 was sold commercially. (My experience was in academia.) It was a port of AIX for PC hardware to the S/390, and to me seemed a bit half-hearted: did not exploit S/390 hardare, toleration only. USS (UNIX Systems Services) is a POSIX layer on top of MVS. The character set is EBCDIC, which any traditional Unix user will find very confusing. Other than that, USS is Unix in that it follows the POSIX specification and has Unix branding, so legally it is as close to Unix as HP-UX or AIX, though it is not what a Solaris customer would expect. OpenVM is a POSIX layer on top of CMS. Here too, the character set is EBCDIC. I am a huge fan of OpenVM (since getting over the char set issue). It is an execellent implementation, but it does lack some important features (notably, fork() is partial). If someone who knows IX/370 or VM/IX could share their knowledge we might learn a little more about the fork() situation along the way. -- R; -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

If I recall some of the commands are like the old VM EDIT line-mode editor. (I used to dial in to VM over 1200 baud line with a print-on-paper terminal - many eons ago.)

Someday I will build in 3270 console support, but until then I have to use PuTTY. tom - - - - - - - - - - - - Toto, I have a feeling we're not in the mainframe world any more. _/) Tom Shilson ~GEDW & VM System Services Aloha Tel: 651-733-7591 tshilson at mmm dot com Fax: 651-736-7689 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Re: Moving root to a new volume
Hi, Yes, but In my example, I was making the old and new root disks available to a second system. In a follow-on note to mine, Mark Post gave an example of doing it all on one system. I suggest that you look at his method first. From Mark's Post Taking the system out of service for such a long period of time can easily be avoided by: 1. Adding the new disk to the existing system dynamically 2. Doing the same dasdmft, fdasd and mke2fs. 3. Following the HOWTO at http://linuxvm.org/Info/HOWTOs/movefs.html from steps 3 to 4, but doing the "cd" to /, instead of /usr. 4. chroot to /mnt 5. Update /etc/zipl.conf, but only if any device numbers will change. 6. Run zipl 7. exit the chroot environment 8. Unmount the new file system. 9. Reboot at the time of your choice. This also eliminates the need to modify all the other parameters in /etc/zipl.conf to remove the /mnt from the directory paths.

Can Linux Console be "Spooled?"
As a long-time VMer (the first Rel 3), when I am working on Linux I really miss having my console spooled, showing all my commands and all my output. I have tried using tee with the shell, but I haven't been able to make it work. Is there any way to do this?
