Re: OSA-ICC HMC panels do not work

Radoslaw, Sounds somewhat like a problem I encountered while installing our EC12. Importing the file from USB would appear to work but got an error during the validate. Looking for my doc. As I recall, it was related to never having any configuration on the OSA-ICC PCHID . Can you manually, with

Multiprise 3000 internal DASD hardware issues

Hi folks I'm bringing up an old Multiprise 3000 - 7060-30. For fun and education rather than production needless to say! All is mostly well so far but I'm having a problem configuring the internal DASD. There are 11 18GB disks in there and 7 SSA jumpers. The loop and plugging rules appear to be c

Here's the CVE: *CVE-2015-5600* http://seclists.org/oss-sec/2015/q3/173 z/OS OpenSSH doesn't support keyboard-interative authentication, so this particular brute force attack on passwords would not apply anyway. I'll also point out a couple of things: 1) All popular security software has defect

Re: rsync anyone?

Gil, I'm not sure if an ssh invocation of pax like this works in all cases. Certainly z/OS to non-z/OS it would not work since, by default, ssh exec sessions are translated EBCDIC/ASCII and vice versa in the z/OS OpenSSH implementations. I would have to check, but this seems unlikely to be binar

Re: rsync anyone?

Gil, Thanks for the correction. I was thinking if he was doing a one-time move he could mount a filesystem on the originating LPAR, do the pax command, dismount, and then mount again on the receiving LPAR. Cumbersome, but works for a one time move. If it is going to be an ongoing process then

AW: rsync anyone?

Dave, a long time ago I looked at the source code of rsync and it is no trivial task to port it to an ebcdic platform (at least it was). A colleague of me was so frustrated too that he wrote a command line tool and a daemon that can be used to sync directories using the "rsync algorithm", but u

Re: rsync anyone?

The pax command is a good choice because it can copy all files, directories, and symbolic links in a directory using a single command without overlaying any existing files. For example: cd /Service/ZOS113/var pax -rvwk -pe * /var Bill -Original Message- From: IBM Mainframe Discussion L

rsync anyone?

Hi, I have been working with IBM to identify how to move a USS directory that has files and subdirectories to a different LPAR. They said Ported Tools and the scp command. However, OpenSSH has had security issues IIRC. The other thing they mentioned was to port rsync over to z/OS. I also ha

Back from Christmas break to a lot of responses - thanks to all. Summarizing the responses thus far: * Select and/or tune your algorithm first. Check. * Tuning for a specific machine is a bad idea because you'll have to retune for every new machine. Check. This code is sufficiently critical t

Re: Is there a source for detailed, instruction-level performance info?

As Tom has noted, the most dramatic performance enhancements typically come from a change in strategy or algorithm used. In my experience you get better results by looking for ways to accomplish the end result by having the program do fewer actions rather than concentrating on micro-optimzing the
