OT - DB2, AS400, Websphere
by Stuart Bailey 03 Mar '13

03 Mar '13

Does anyone have any experience of DB2 / AS400 and Websphere I have a project to replace an existing website (with database backend) onto an OSS system using a LAMP server. Trouble is, the AS400 is used for all the financial site of the website. I do not have the source code for the websphere component, but will need to reverse engineer this in order to replicate the communication with the AS400 on the LAMP server. Does anyone have experience of these systems, or know anyone who does?

after another mysterious crash
by Peter Alcibiades 03 Mar '13

03 Mar '13

Another mysterious crash. We run for three weeks or so continuously, no power off, then suddenly it dies. This time I thought to start from system rescue disk and try memory checks. This did seem to produce reporducible dying. After three crashes in a row I decided to bit the bullet and replace the innards. Yes, it would be possible just to replace the memory and see if that helped, but its productive time being lost at every iteration of this problem. The result is surprising. Now I have 16G memory in two sticks, and an i5 processor in an Asus itx board. It is a lot quieter and a lot cooler than the previous rig. In fact you can just about hear it. Started from the old hard drive with no problem and everything runs perfectly though rather faster. So, if you are looking for a compact and fast configuration, get the Silverstone mini itx case with the big fan on the front, put an i5 in it, and its perfect for a compact desktop. Recommended. I liked it with an i3, but this is superb. Al

http://www.kickstarter.com/projects/1755283828/open-source-edition-of-livec… Gone open source. Its a successor to Hypercard, but across all platforms including mobile, and they raised enough money to modularise the code and take it open source. Well over subscribed. Very encouraging. Peter

Do I use rsync or cp?
by Chris Walker 26 Feb '13

26 Feb '13

In the recent past I asked about fixing a RAID array on a NAS drive and was kindly given some advice by Mark Rogers. Plainly a sensible option and which was included in the advice, was to have a backup. So yesterday I went out and bought a USB3 1 TB external drive along with a new USB 3 card. I've bunged the card in and got all sorts of errors, something about 'ring error' which from my brief searches relates to the kernel being too old. I'll attend to that later as I can still use the new drive on a USB 2 port. Granted it will take longer but I can live with that. My question is how should I safely copy everything off my NAS box on to the new drive? Should I just use cp or rsync? The emphasis here is 'safely' as I want to make sure I copy everything off the NAS and back again in case that goes 'nipple north'. If it helps, here's what I want to copy from - //storage_server/Laptop_Share on /media/Laptop_Share type cifs (rw,noexec,nosuid,nodev) //storage_server/FTP_RAID_C on /media/linux_Share type cifs (rw,noexec,nosuid,nodev) //storage_server/Epox_Share on /media/Epox_Share type cifs (rw,noexec,nosuid,nodev) //storage_server/Media_Share on /media/Media_Share type cifs (rw,noexec,nosuid,nodev) In the past I would simply have cp'd everything off but having watched the recent discussions on rsync, it has prompted me to ask this question here. Any help appreciated.

I thought I understood rsync, but clearly I don't
by mick 16 Feb '13

16 Feb '13

As it says really. I need some advice on an rsync mechanism I use to routinely backup my desktop to my NAS. The command I have used for some time is: /usr/bin/rsync -rLptgoDvz --stats / --exclude-from=rsync-excludes /home/mick nas:/home/mick-backup ("/" indicates line break above and is not part of the command line) That has worked fine for some long time, but I have just upgraded my desktop disk from 1TB to 2TB. In the process of doing so I moved the old disk to a new SATA port so that I could just copy across internally all my data from the old disk to the new. In doing so (using something like "cp -r /old-disk/micks-stuff /new-disk/micks-stuff") like a pillock I forgot to add the -p switch so all my files now have a current date/time as last modified. Guess what? My latest rsync now seems to be updating ALL by backed up files (over 800 GB of videos/photos/music etc) to the NAS. This will take some time. I thought that rsync used a rather more sophisticated algorithm (including checksums for example) than simply a check of last modified time stamp. In trying to reduce the file transfer I have tried modifying the rsync command by taking out the -t switch, but of course that doesn't work, all that happens is that the target file date/time remains unmodified after the copy. So, short of actually letting the rsync run to completion, can anyone suggest a better approach (and yes, I know I could have saved myself a lot of pain by being more careful earlier....)

"Correct" way to mount CIFS shares after network comes up and unmount them before it comes down
by Mark Rogers 15 Feb '13

15 Feb '13

As per subject really! On my old PC I had CIFS entries in fstab and scripts in /etc/network/if-up.d and if-down.d, and whilst the mount worked well the unmount usually locked the PC on shutdown (SysRq-B was about the only thing it would respond to). I now have a new PC so I want to set this up correctly. All I want is that when eth0 comes up, several Samba shares are mounted, and before eth0 goes down they are unmounted (forcibly if necessary). I've looked at upstart as a possibility but I don't see how to run a script before networking goes down, unless I edit the relevant network script (I don't want to change system scripts). In case I'm overcomplicating this, all I really want is a handful of shares to be available whenever the network is, and for them not to cause me problems if I restart or shutdown networking. I'm using Kubuntu 12.10 -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Two network switches free to a good home
by Srdjan Todorovic 15 Feb '13

15 Feb '13

Hi all, I've got 2 network switches free to a good home. They are untested (fans spin and LEDs light up, but not tested network ports), but I have no reason to suspect they are duff. They are: 1. CentreCOM FS716 16-port 10/100 mbps switch. 2. Netgear FS518T 18-port switch. 10/100 mbps for ports 1-16 (I think) and 1 Gbps for ports 17 and 18. Both do not have the auto mdix thingy so you will need correct patch ethernet cables (port 16 has the ToPC / ToHub toggle button on both switches). Both are powered using mains kettle cable (not supplied). Both have fans (the Netgear is a fair bit louder). Both are about the same size, just bigger than A4 paper I'd think, and metal cased, about 1U high. Google the dimensions if you want. I can bring them both in to this week's ALUG meet in Norwich. If anyone wants them, let me know so I can stick them in the car for the meet. Regards, Srdjan
