As Mark said, there are products that will do this on certain flavours of *nix. However they have their own, erm, peculiarities. The one that we used at my last job insisted on using it's own version of the pam modules to keep everything under control. I wasn't very happy about this but the

Re: what is the page size reported on the perfomance monitor tool kit

2004-04-23 Thread Post, Mark K
Page size is 4K. Without also seeing what Linux thinks is happening, it would be hard to say if your storage allocation is appropriate. Based on the fact that you're doing no paging at all (during the reporting period), I would say you're likely grossly over allocated. Very few things in Linux

I updated zipl.conf incorrectly :(

2004-04-23 Thread Ken Vance
Hi, Thanks for all of the responses yesterday in regards to the 26 disks question. We were working on this today, but unfortunately I updated the zipl.conf incorrectly. On the dasd= parameter, I added a comma after the last device range. This should have been a blank. The ZIPL was run, and

The question I have is whether the read-only root file system you have is an initrd, or real DASD. I would think it's an initrd. In which case, you should be able to mount your real root file system, chroot to it, and fix zipl.conf. Mark Post -Original Message- From: Linux on 390 Port

Virtual Storage Tuning Whitepaper for Red Hat Enterprise Linux 3

For all those people that have asked about possible virtual storage tuning knobs for Linux, a couple of Red Hat employees have put together a short whitepaper on the subject that is (perhaps) specific to RHEL3. http://people.redhat.com/nhorman/papers/rhel3_vm.pdf Not being a performance person,

3 zVM's on same Mainframe Shared DASD

I am going to be installing 3 different zVM's on the same z990 for 3 different sets of engineer departments. Shared DASD. What are the implications of using same VOLID's for 440RES W01 W02 etc. Does zVM detect duplicate VOLSERs (like z/OS) during IPL? I'd prefer to change these VOL ID's and

Linux and buffers and memory allocation

I know that linux is buffer happy. Exceptionally so. Just got the while VM thing going, and that went smoothly enough. Now I'm trying to tune memory so that linux paging is minimized but VM paging does not increase as a result. I have one guest with 1.3 GB real (for Webspher ND) and it tends to
