Anybody tried installing Arch on HP Pavillion TX series?

those with the rotating touchscreen and all?
tried tuxmobil and linuxonlaptops, they only have articles on Ubuntu and Fedora.
can there be any problems specific to ArchLinux, or is it safe to buy the notebook and try installing Arch, since Fedora runs well?
thanks.

Let us know how this turns out. I was thinking about going after that series, but I can't abandon Arch. :-)

Anybody tried install oracle 10g into Microsoft Windows Server 2003

Dear sir/madam
I would like to know is anybody tried install oracle 10g 10.2.0.1.0 into Microsoft Windows Small Business Server 2003?
Will it works smoothly? any problems about it? any networks problems?
I am prepare to buy Genuine Microsoft Windows Small Business Server 2003, so I would like to know about this matter.
many thanks

While I have not installed Oracle on Windows 2003 Small Business Server, I would suggest that you not install on that particular version of Windows. While I have not worked with SBS, I believe that this is an all-in-one solution that handles Exchange email services, file services, print services, domain control (all roles), DNS, WINS, HTTP, and probably a couple other things also.
While it sounds like a great idea to add Oracle to this server, I suspect that you will encounter some of the same issues that cause problems when Oracle is installed on a Windows domain controller. On such a server, there is no concept of a local group (the ORA_DBA group that the installer tries to create). Available memory, availalble free CPU, and disk contention may also be a problem due to contention with other services running on the server.
You might take a look at the following Metalink articles:
Note:46001.1
Note:77665.1
Note:160538.1
I would suggest that you take a look at the 64 bit Standard Edition of Windows 2003 if it is compatible with your hardware, or if you are familiar with Linux, do as Aman suggested. If possible, run only Oracle on the server.
Incidentally, Windows 2003 SBS is not listed on Oracle's certify web page, even though Windows 2008 is listed.

Trying to install arch

well a while ago I tried installing arch but then gave up on it since I have limited bandwidth and cannot download large packages like GNOME at anytime but now i wanna try again. So i setup my system to install on an external hard drive. I configured all the files and installed the packages but when I went to set the root password i got a bunch of errors i think saying:
/arch/setup: line 1406 : 30000 Segmentation fault chroot ${DESTDIR} passwd root
arch/setup: line 1406 : 30000 Segmentation fault chroot ${DESTDIR} passwd root
arch/setup: line 1406 : 30000 Segmentation fault chroot ${DESTDIR} passwd root
arch/setup: line 1406 : 30000 Segmentation fault chroot ${DESTDIR} passwd root
with the 300000 going from 1-about 40000 in a few seconds. it has been doing this for a few mintues waht is the problem? any solution?

Hi
Thank you for the reply and information. I have gotten further. I am now stuck at installing the boot loader. I get an error that says:
Unable to find OpenFirmware path for boot=/dev/sda2
Please add ofboot=<path> where <path> is the OpenFirmware path to /dev/sda2 to /etc/yaboot.conf
So I have Googled and that ofpath should give me this information. But I then get this error when I run ofpath /dev/sdb2:
Unable to determind controller path!
Am I doing the right thing to find out the OpenFirmware path? Is there anything else I can try?

fsck -f /dev/sda2fsck makes no sense because /dev/sda2fsck is not a deivce. If the wiki says that, then it is wrong. It's only doing a fsck anyway so probably not really needed. If you are just formatting th swap partition then use, mkfs.ext{234}.

Trying to install Arch on a SD card.

I have an EEE PC 900 and was trying to install arch on a 32gb sd card.
Every kernel I have tried so far boots then during bootup says it cannot find the root drive.
I tried changing the root delay but that didn't work. So far I tried the defalt kernel and toofisnes's kernel and both came up with the same error.
Can anyone help point me in the right direction?

Good. Glad to hear that your motherboard supports usb boot. However, you did not understand my question.
Think back to when you installed Arch And it asks if you want to boot from an encrypted/RAID/LVM/USB/etc root partition? That USB option is pretty important. (Post-install it is one of the mkinitcpio hooks.) Without it, your kernel will not have the drivers to read your root partition.
Reinstall from the Arch iso. When you get to the kernel step, it will ask "Do you want to boot from USB?" Select "yes".

Has anybody tried to install RAC on Zones as nodes ?

Hi guys,
Could anyone share his experiences about installing Oracle RAC
on Solaris zones located on single physical machine ?
I created 2 sparse root zones , presented the same raw devices for ocr and votedisk to them and try to install clusterware,
but during clusterware initialization there is an error
OCROSD[1]utsz:3: ioctl DKIOCGAPART failed. errno 48
Does anybody tried similar configuration ?

I have not tried this since it is explicitly unsupported by oracle.

When it comes to installing the packages I get and error about "key could not be looked up remotely" with different keys mentioned. I have tried changing the SigLevel to Never in /etc/pacman.conf but this seems to get over written when I start the package install form the installer (/arch/setup). How can I get round this?

Trying to install Arch Linux on a HP-dv2000 laptop

I am able to start up from, the CD no problem. I get the Arch Linux menu. What I think is the problem is maybe a resolution issue because as I go to install it, the screen looks wonky and I can't see the command line properly. I know when I install Ubuntu for example, the installation screen looks off to one side. Only after installing the nvidia driver after successfully installing Ubuntu does the screen look the way it supposed to.
I think the same think is happening here when trying to install Arch Linux. Any suggestions on how I can resolve this? This is a big deal for me because for the first time, I think I am going to learn a ton of stuff about Arch Linux. I am willing to take the plunge following the beginner's guide along the way.
Thanks for the help!!

ArchLinux is designed to run whether in VirtualBox or on a real machine.
If you have a TV connector plugged in it will chop some regular lines at the bottom to make up for the difference in TV resolution.
There are a couple of packages related to nvidia hardware, nouveau is one of them. Just do a pacman -Ss nvidia for possibilities of things you might need to install. Your nvidia hardware is a little newer, so probably nvidia is the package you'll need instead of nouveau.
Are you using X? When you install the proper xf86-video-* driver it shouldn't have any problems with X. If modesetting is turned off, then some resolutions may not be made available (especially in Gnome), so it is best to keep it turned on if at all possible (kernel default).

Trying to install Arch with Ubuntu hardy already installed

I have Ubuntu already installed on my system and I want to install Arch on a separate 10gig partition ( which is already made) but when I boot from the Arch cd and go to install Arch only sees the main drive it doesn't see anything else what am I doing wrong. I only want to install arch on the 10 gig partition for now until I am more familiar with Linux

Dual booting with other linux distros
This is done exactly the same way that Arch linux is loaded. Here we assume that the other distro is on partition [s/h]da3.
title Other Linux
root (hd0,2)
kernel /boot/vmlinuz (add other options here as required)
initrd /boot/initrd.img (if the other kernel uses/needs one)
[edit] Dual booting with other linux distro (Chainloading)
To avoid maintenance nightmare, you might want to chainload the GRUB in the MBR to another bootloader you might have installed in the bootrecord of a partition [(hd0,2) in our example] instead of the MBR. This way the auto-magic stuff of some distro will manage the menu.lst on (hd0,2) (if it is grub) for its own distro and you will boot with all the option needed (like the correct last kernel) without the need to copy/paste some part of that menu.lst into yours.
In our example [1], GRUB is in the MBR and some other bootloader (BL) (be it grub or lilo) is in the Boot Record of (hd0,2).
| | | | % (hd0,2) |
| M | | | B % |
| B | (hd0,0) | (hd0,1) | L % Other |
| R | | | % Distro |
| | | | % |
| ^
| chainloading |
Then, you simply use in your menu.lst:
title Other Linux distro
root (hd0,2)
chainloader +1

Installing Arch on Asus Eee, Already Read the Wiki [Solved]

I'm attempting to install Arch on my Asus Eee 701 (4GB SSD model) and I made a mistake that I'm having trouble correcting. First, I accidentally wrote the image to my Eee's SSD, instead of my USB drive. I tried to install Arch with the installer on my SSD, set up the partitions (one for /, one for /boot, and one for /home), but when I issued the command, it told me that the disk was in use. It was then that I realized what I did. I used an Ubuntu LiveCD on another computer to burn the image file again, this time to my USB drive. I booted my Eee from the USB drive and tried to partition my SSD again, but this time, it tells me:
Device or resource busy
This disk is currently in use - repartitioning is probably a bad idea.
Unmount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
Use the --force flag to overrule all checks.
When I boot from my SSD, I get the same message, so I'm not even 100% certain that I booted from my USB drive before. My USB drive's activity light was on though.
Is there any way to fix this? Also, given that I have an SSD, what partitions should I set up and how big should they be? I can't find any concrete numbers in the wiki.
Thanks in advance for the help.
Last edited by Tyrian (2008-11-17 04:14:23)

I'll try that, thanks. What would happen if I dismounted the SSD with -f if it was in use?
EDIT: I just realized that when I go into the installer, it lets me set up partitions manually (I run the installer, pick "Prepare Hard Drive", "Partition Hard Drives", "/dev/sda"). But how should I set them up? When I test it by just making one 4GB partition, it tells me, "Wrote partition table, but re-read table failed. Reboot to update table." So I rebooted, and it appears to work. So I deleted that partition, made a 512MB one, rebooted, and repeated until I had 3 partitions in ext2, a 512MB (sda1, bootable), 512MB (sda2), and one roughly 2.5GB (sda3). I then went to "Set Filesystem Mountpoints", said "NONE" for the swap (due to the avoiding pitfalls section of the wiki), picked "/dev/sda1" as "/" in ext2, made "/dev/sda2" as ext2 called "/var", and made "/dev/sda3" in ext2 called "/home", then said "DONE". When I say "Yes" as the confirmation prompt, I get this message:
Error creating filesystem: mke2fs /dev/sda1
I hit enter and get dropped back to the "Prepare Hard Drive" menu. I followed this section of the Beginner's Guide too.
Is there any way to fix this?

Has anybody tried the Day-Timer iPhone App - Syncs. Calendar + Todo list?

I have had my iPhone 3Gs calender sync. break several times,
and honestly none of them seem to be my "fault". I stumbled across this app. and for $6 I'd take the cowards way out rather than try to fix my current broken sync. problem with iTunes. Has anybody tried this?
http://www.daytimer.com/iphoneapps/
Frankly the demo. seems pretty clever:

I have not connection with Day-Timer company... other than being a potential customer

Vlingo doesn't consume all the app memory space itself... it can be used by a number of factors, including the browser cache.
Your unintall of Vlingo also caused a reboot of the device in which all the free memory space was cleared, from routine use of the BB device.

Installing Arch Linux on USB key: error while booting

Hello,
first of all, I must say I've followed the steps from this article on arch wiki to install archlinux on my USB key: https://wiki.archlinux.org/index.php/In … _a_USB_key
So what I did is to use one of my 2 usb keys to INSTALL linux, and the second one to RUN linux. I used dd to write on the 1st usb, eveything worked fine when booting, then I do install arch on the my second usb following the stept from the link above, everything works until I get this error while booting (at the middle):
Waiting 10 seconds for device /dev/sdc/
Root device '/dev/sdc' doesn't exist. Attempting to create it.
ERROR: Unable to determine major/minor number of root device '/dev/disk/by-uuid/lotsofnumbers'
You are being dropped to a recovery shell
Type 'exit' to try and continue booting
/bin/sh: Can't contact tty; job control turned off
[ramfs /]#
To summarize I'll show you my conf files that could help you to resolve my problem:
/etc/fstab.conf
/dev/sdc1 /boot ext2 defaults 0 1
/dev/sdc2 / ext3 defaults 0 1
/dev/sdc3 /home ext3 defaults 0 1
So here I've sdc1 boot 32MB partition; sdc2 root 3GB partition; sdc3 home 978MB partition for a total of 4GB USB key~
I didn't make a swap partition as in the tutorial they are writing it's unnecessary for some kind of reasons.
/etc/mkinitcpio.conf
HOOKS="base udev usb autodetect pata scsi sata filesystems"
I've added to here, "usb" to the hooks
installed GRUB on my sdc, here is the menu.ist:
# (0) Arch Linux
title Arch Linux (USB)
root (hd0,0)
kernel /vmlinuz26 root=/dev/sdc ro vga=773
initrd /kernel26.img
So, I boot GRUB without problems, start Arch Linux, but then I got this error above.
I've searched alot on some forums and read many stuffs, but sitll can't fix it and it seems complicated.
I've tried to boot with UUID, also, but didn't make difference. I tried to remove some parameter from the hooks, but unfortunately this wasn't working still. I've read somewhere to use chroot, but I didn't catch on how to do that and what was the use of chroot, I'm still noob user of arch linux and currently learning. Maybe it's the problem, as some forum were talking about creating a new image, but I still don't know how to make it. By the way, I'm not sure this could have fixed my current problem. I've also read somewhere it could be due to my lack of space, but I wrote you how I did partition my USB key, let me know if you have any suggestion please.

1. What I did is re-installing entirely from my installation disk or USB to test out different setting in my config files, because I don't know how to edit my .conf as I can't really finish to boot to the end and get in terminal mode? If there is a quicker way to edit files from any terminal to go into my current USB sdc to modify directly my file from there, I'd enjoy probably. So rebuilding the initpio, no, I just re-installed to test out different configs.
2. Yes, same error.
3. Tested out by-id/by-path and uuid = no difference
4. Didn't know about larch, it seems to be a nice tool, I'll check it out

Install arch on a read-only filesystem

Hi to all, I have an idea about installing arch in a particular way, a way that makes the system more secure.
I want to install a host archlinux system on a hard disk or ssd but I want no data can be written to the storage. The host system will have a predefined set of programs and should use a ramdisk to store temporary data. It is something very similar to a ISO.
The real computation will be handled through a series of virtualbox instances of linux ( the virtualbox images will be stored on an external hard disk, a read/write volume ).
How could I achieve this? Through unionfs? AUFS? or some other thing?
Last edited by pabloski (2011-02-16 16:18:11)

I want to mount my sda2 read-only and union it with a tmpfs, so the machine is secure and the file system is the same every boot.
I installed aufs3 with 3.2.6-1-aufs_friendly, I made a hook (as some-guy94 adviced), but it doesn't work.
The code is:
1. mkdir -p /root/ro /root/rw
2. mount /dev/sda2 /root/ro
3. mount -t tmpfs root.rw /root/rw
4. mount -t aufs -o "dirs=/root/rw=rw:/root/ro=ro" root.union /
At 2. it says: "mount: mounting /dev/sda2 on /root/ro failed: No such file or directory" Both files exist - I can list them just before the mount.
3. & 4. work, but it doesn't matter as sda2 gets mounted rw on / right after (by initramfs's init, I gues).
Can you help me with this, or point some useful howtos?
Btw: is there a better way of debugging a hook, other than making the image and rebooting each change?
Update: This is how they did it in larch: http://git.berlios.de/cgi-bin/gitweb.cg … cpio/hooks
mount -t ext3 /dev/sda2 /root/ro works now.
I used exec /sbin/switch_root as in larch3 hook and for loop from /lib/initcpio/init:109 to move /proc /dev /sys /run to the new root
So the union mount works just fine now, my sda2/sbin/init & sda2/etc/rc.sysinit run, but the latter fails with following:
* Mounting Root Read-Only - this is actually quite acceptable
* Starting UDev Daemon
* Loading Modules
* Remounting Root Read/Write - acceptable as well
After boot X opens and system freezes immediately (no reaction to keyboard, doesn't ping). No useful information in logs. I don't think system can run well without udev/modules. So this is udev not liking / mounted rw (as tmpfs is rw) or maybe /dev /proc /sys /run fault.
I tried to make union mount only in rc.sysinit when /dev/sda2 is already mounted on /, but mount --move / other-dir fails.
Any ideas what can be wrong?
My code:
run_hook ()
read -p "Union mount root (y/N)? " answer
if [[ "$answer" == "y" ]]; then
modprobe aufs
ro="/root/ro"
rw="/root/rw"
un="/root/un"
rob="${un}/ro"
rwb="${un}/rw"
mkdir -p $ro $rw $un
mount -t ext3 /dev/sda2 $ro
mount -t tmpfs -o "size=20%" root.rw $rw
mount -t aufs -o "dirs=${rw}=rw:${ro}=ro" root.union $un
mkdir -p $rob $rwb
mount --bind $ro $rob
mount --bind $rw $rwb
mkdir ${un}/media
mkdir ${un}/sys
mkdir ${un}/proc
mkdir ${un}/dev
/bin/mknod ${un}/dev/console c 5 1
echo "rootfs / rootfs rw 0 0" >${un}/etc/mtab
[ -z "${init}" ] && init="/sbin/init"
if [ -e "${un}/${init}" ]; then
mount
read
for d in proc sys dev run; do
if [ -d ${un}/${d} ]; then
mount --move /${d} ${un}/${d}
else
umount /${d}
fi
done
exec /sbin/switch_root -c /dev/console ${un} ${init} ${CMDLINE}
fi
fi

Installed Arch on external usb drive: Drive errors after reboot

I installed Arch on my external usb hard drive and everything seemed to be working fine. After rebooting though, I had a bunch of filesytem errors (ext3) and the system was unstable. I am guessing that this has to do with the unloading of the usb modules at shutdown. If this happens to early, then the root drive doesn't have a chance to shutdown properly, hence the filesystem errors.
Anyone know how to solve this?
Thanks!

EtreCheck looks at your log files for any kernel I/O errors. That is what it is reporting. EtreCheck just reports what it finds and tries to avoid judgements exception the most extreme cases. The drive might be OK. I am seeing more reports of this than I would have expected. It may just be a problem with Yosemite. It really prefers SSD disks in all cases. On my own machine, I have seen a slow external drive exhibit classic failure symptoms and sounds when connected via USB2. But then when I switched to FW800, it was fine. Other people are reporting that when they downgraded back to Mavericks, their disk errors went away.
So, I don't have a good answer for you. The drive might be bad, and it might be fine. Yosemite is definitely having problems with it. You may experience performance problems with that drive attached.

Anybody tried installing Arch on HP Pavillion TX series?
