updated UFT for Linux

The POSIX implementation of UFT is kinda old. I have updated some of it from time to time, but I did a more rigorous clean-up over the weekend. It's now reasonably 21st century code. This release 1.10.2 includes two (untested) RPMs, one for 64-bit AMD/Intel and another for 64-bit Z.

I STRONGLY recommend LVM because it provides generic volume management. What is your workload? If you're just running applications and databases in Linux then I'd recommend LVM+EXT in favor of Btrfs. responding interleaved On 01/12/2018 07:00 AM, Roger Evans wrote: > ?I have had a bad

Re: Recommendation on FSTAB Options

I was going to say, as Berry says, that UUID is the current trend. It's like a superlabel if you're okay with mount-by-label. (A certain other distro threw mount-by-label at me, which aside from the astonishment factor is not a bad idea.) Linux FS labels are (duh) the moral equivalent of IBM

XMITMSG work-alike for POSIX/Unix/Linux

I posted to IBM-MAIN and to IBMVM about this. Thought I had posted here too but can't seem to find it. (The mind ... always the first thing to go.) Minor events in a GitHub project drove me to re-visit doing 'XMITMSG' on Unix/Linux circa Thanksgiving. This is a re-do. I had written a POSIX

CMS style XMITMSG for Linux and Unix and similar platforms

I mentioned on IBM-MAIN and on IBMVM that there is a simple but workable "xmitmsgx" library to do on Unix/POSIX what the 'XMITMSG' command and the APPLMSG macro do on VM/CMS. This is not the first time this thing was tried. But life happens and more important things get attention. It seems to be

Re: Gold On LUN

Don't clone! Just link! I do, and have done, a fair bit of cloning. But I don't recommend it for production systems. (dev, test, recovery, sure) Instead, _share the OS disk or LUN_. Give each "client" (for lack of a better term) its own root. Less to backup, less to push with Puppet, more

CMS FS driver - the old one

The current FS driver for /mounting/ CMS minidisks to Linux is cmsfs-fuse. This note describes the old one. The only advantage to the old driver is that it was wholly kernel space. FUSE is common for a lot of filesystems these days, ostensibly isolating the riskier logic from kernel space. On

CMSFS utility

Good questions, Paul. Copying the Linux-390 discussion list because it seems relevant. I'll discuss the filesystem driver ("cmsfs.o" below) in a separate note, but the CMSFS utility was written for maximum portability. Got an update from Dan Horák a year or five ago, and that should be in the
