in your original email i saw you formatted the V-DISK using using the CMS FORMAT command I do not see on your linux side where you create a swap partiition on these devices. i.e. mkswap /dev/dasdb and so on the CMS Format does not write a SWAP signature onto the V-DISK. we use the swapgen util t

I am going to bump it's storage back up before I go home. Interestingly enough - although I see swap being used on other servers I do not see it used on the servers running this particular application. But I was using vmstat while the customer created the problem and I swear I saw swapping. I'll

hmm.. I just tried this on my Linux workstation and the numbers are pretty close between free -m and swapon -s. Could it be that something is attempting to load into memory that can't be swapped out and really needs more than 128M?Maybe try 256M and see how it goes? Others here probably have

What about "free -m" -- does it show swapped being used? I've only used swapon -s to see what devices are there and their priority... So I'm not sure of the accuracy of that 'Used' number -- would just want to compare with free -m results... Scott On Tue, Jul 29, 2008 at 3:47 PM, Smith, Ann (

Then there's nothing you should need to do but restart the server.. see my previous post if you're trying to do it dynamically without restarting.. Do the swapon -s to determine what swap disks are being used.. Scott On Tue, Jul 29, 2008 at 3:33 PM, Smith, Ann (ISD, IT) < [EMAIL PROTECTED]> wro

Yes. I think the server had swap disks. I just want to increase the size of the V-disks. I increased them as far as VM is concerned. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Scott Rohling Sent: Tuesday, July 29, 2008 5:28 PM To: LINUX-390@VM.MARIST.

Oh - and to add swap dynamically: Bring the vdisk or real disk online: chccwdev -e address address being the appropriate virtual address of the disk Make the disk a swap disk: mkswap /dev/dasdX Tell Linux to use it: swapon /dev/dasdX X being the appropriate drive letter.. Scott On Tue, J

2008-07-29 Thread Scott Rohling
A little confused because you seem to be indicating the swap disks are used, but are asking how to get Linux to use them? Anyway -- your swap disks are probably defined in /etc/fstab - so check there to ensure they are all mounted as swap. If you've added any disks, add the appropriate line to t

I have a SLES10 server that is running a java app using tomcat5 and is hitting out of memory conditions.

Hi there is there an easy way to map USS UID/GID from z/OS USS to Linux accross an NFS mount point ? In older versions of NFS there was a map_static=map.file parameter where you could build your own static mapping table, but in NFSv4 it seems to have gone. We dont have a common LDAP or NIIS ser
