HSM-like function on Linux on z

2008-10-20 Thread Lee Stewart
Over a year ago there was a discussion with people looking for an HSM-like migrate and retrieve function for Linux. Back then it sounded like there was interest, but no solutions. Since it's been a while, has anyone heard of anything new in this space? Thanks, Lee -- Lee Stewart, Senior SE S

Hi, I think the best way to shutdown is to use the SIGNAL command with the maximum timeout value of 32767 and using the kernel 'vmpoff=LOGOFF' parameter in the /etc/zipl.conf. This way CP will try to logoff the machine only after about 9 hours (more than enough to fix any delays) and Linux kernel

Re: Lin_tape build question

2008-10-20 Thread Hall, Ken (GTS)
It's the "clean" that seems to be causing the trouble, and it shouldn't be needed. Change the SPEC file in /usr/src/{whatever}/SPECS to remove that in the "build" section, and try a manual rebuild ("rpmbuild -bb lin_tape.spec"). My copy of 1.15 doesn't have that, and builds correctly. Haven't tr

SLES10 in an LPAR and kernel.hz_timer

2008-10-20 Thread Ron Foster at Baldor-IS
Hello all, I have been looking at our sysctl.conf parameters to ensure that they are set properly. Back in early SLES9 days I found a recommendation somewhere that said that if you were running SLES9 in an LPAR, you should set kernel.hz_timer=1. And for Linux under z/VM, you should set kernel.h

I usually give a high timeout like . Then when machines don't come down within say half an hour, there is ample time to investigate why before the CP killer hits. Best regards, Pieter Harder [EMAIL PROTECTED] tel +31-73-6837133 / +31-6-47272537 -Oorspronkelijk bericht- Van: Linux

Good insights, Barry. I didn't consider the possibility of long running database users. Surely if they're still connected the database will likely not want to shutdown. Unless there's a shutdown option to ignore connected users unless they're actually active (I'm not that familiar with Oracle

Hello Rich, Indeed, if the application has the correct init scripts and the SIGNAL is trapped to a "shutdown -h now" then a SIGNAL would correctly shutdown the application and the guest. But only if the SIGNAL has been given enough time to shutdown before CP will force the user. That would trigge

I think the problems are the vended products for which you cannot obtain source, and for which the vendor is unable or unwilling to create zSeries binaries. An Intel binary executor on p Series makes sense for this; you can move the product and run it, with very little hassle. This would be a fine

I fail to see what z/OS has to do with any of the discussion at all. I thought we were comparing to zLinux and the z/VM environment. zLinux is much closer to Linux than AIX is... Because it IS Linux. It can run bare bones, or using z/VM as a hipervisor, and z/OS doesn't have to be present at all.

Not every site will have the environment, structure, or support personnel to install and maintain a z Series system and keep up with its needs. In order to cover as many markets as possible, I think it is wise of IBM to supply the alternative structure in the p Series machines. This covers the mark
