Now Im puzzled, I wasnt aware of the fact you have to pay for an PAV license. I didnt read the whole story. I was sure, that PAV is only an eckd-linux-driver bussiness, wich isnt developed/released yet. Perf: The goal is, to get the most perf, lowest response time, best scalabilty, and of

Re: down load site for: webmin

I need to look at the support for administration of LDAP user accounts. What is a good freebee product for LDAP admin if not webmin ? I see that cpu, gq, and directory_administrator come on the SuSE SLES8 CD's. Any recommendations ? TIA

Re: Linux 2.6 Kernel

Gregg and Arnd, Thanks very much for your input, guys! As you may have deduced, I'm working on finding ways to safely and easily allow kernel and application sharing work on the 2.6 kernel. It -does- seem that the early mount of /dev/pts is causing my difficulties, and I'm having trouble

Forms flash or overlay printing

I need to do some quick research as we may be heading very quickly to disaster mode. We have a Xerox 4890 laser printer (one of those big things) that is channel attached. It broke over the weekend and Xerox has been trying to fix it over the last few days. Well we have voter notification

Re: Forms flash or overlay printing

Tom, Forms overlay is not described, but for basic setup of CUPS (sounds like you won't need Samba) on SLES-8 see the redpaper Printing with Linux on zSeries Using CUPS and Samba on the Web at: http://publib-b.boulder.ibm.com/Redbooks.nsf/RedpaperAbstracts/redp3864.html?Open -Mike MacIsaac, IBM

Re: Forms flash or overlay printing

Two suggestion: 1) find the nearest Xerox demo center and cut a tape with the output. Road trip. 2) use the forms functions in CUPS to print the form and the output simultaneously. You can feed this via RSCS to CUPS and get CUPS to add the form w/o too much trouble. Contact me offline for how to

Re: Forms flash or overlay printing

Thanks Mike I'm reading it nowand configuring...neat stuff. I'm always amazed that this stuff works. I've configured a CUPS printer, brought up the web stuff, printed test pages (that took way, way too long to print, but great resolution). Although I can't configure printers or modify

WG: Performance of large file systems

But we have big performance problems on an 40GB fs (LVM, 10 Stripes on M9, 4 phys Escon) with an mySql-DB on it. Reorgs and even selects sometimes takes a lot of time. (Same on SCSI-Raid is double-performance) Two things: 1) A reorg does both a read and a write, so the activity of the 4 escon

WG: Performance of large file systems

Aren't the DASDs virtual in the storage boxes?? Tracks are living anywhere!? That may be true for the RVA, which is a log structured array (paging) device that maps a page anywhere in the backend. On a shark, each LSS is a separate RAID 5 group and device addresses are assigned sequentially in

Dirt Simple Monitor

I have been playing around trying to make a simple monitor like top for vm. If you create two files MONITOR EXEC and MONITOR2 EXEC you can see what I have been up to. I have not written any vm scripts for 10 years and had never seen cms pipes before so Im sure there are better ways to do this.

Looking at some previous posts, Maybe MONITOR is a bad name Im trying TOP for a while to see if that causes me any problems. Mike Caughran wrote: I have been playing around trying to make a simple monitor like top for vm. If you create two files MONITOR EXEC and MONITOR2 EXEC you can see what I
