Power Down while creating array...

Hello all,
I just found out that I need to do a unexpected shut down of an Xraid tonight. No biggie except for the fact that one side is 45% done burining in a new array.
If I power down the Xraid while the array is being created would it somehow harm the hardware? I can deal with starting the burn in again, but I don't want to damage the physical disks..
Any help would be appreciated.
Regards,
Daniel
XRaid

Called Support on this. As long as the Raid is powered down correctly before the plugs are pulled, the burn in should continue where it left off when the raid is powered back on with no damage. Worse case scenario is you have to rebuild the array from the start.

Tax code does not show in Drop Down while Creating SC

Hi all,
While creating Shopping Cart Tax code drop down only display Taxable.
This Taxable we have made as default in the configuration. We have same configuration transported from our Development box to Quality box.
In Development box Requestor can see Taxable and non-taxable in the drop down while in Quality box only Taxable is showing in the drop down.
Has anybody came across this kind of prob
Regards,
Smita

Hi
Configuarion is missing in this case.
Please maintain data in the following tables in SRM side, similar to what is maintained in R/3.. In order to go ahead further.
The main tables are as follows ->
BBP_TAX Tax Codes for Enterprise Buyer
BBP_TAXT Enterprise Buyer: Tax Code Description
BBP_MAP_TAX_CODE ( Assign Enterprise Buyer Tax Code to FI System )
BBP_DET_TAX_CODE ( Tax Code Determination )
Please go through the following pointers which will definitely help.

T61p power down while idle in docking station

Hi,
I have a weird problem with my T61p. I work for hours when the laptop is docked, then I leave it alone for a few minutes and when I come back it is powered down. There is no indication that it shuts down Windows XP cleanly, since unsaved work disappears. It appears as if it shuts down as if I would hold the power button.I have the same problem with my docking stations at home and at work.
Any help would be appreciated!
Thanks, cj

Thanks KiDYu, unfortunately it didn't help....
Getting back to this 4 month old problem (actually, 1 year old problem...). I have been trying many different things (driver updates, monitoring temp, using TPFanControl to monitor/control fan).... nothing helps. When I work with my laptop docked everything is great, when I go get a coffee I come back and it's powerd off.
My typical temp (right now, after using it, Pandora running in the background) while docked is CPU 81 celsius, gpu 78, pwr 69. Seems to be within reasonable limits. Also it doesn't seem like the temp should go up when I'm NOT using the laptop, so I doubt this is a overheating problem.
My best guess is that something in the power management software detects "idle" after some minutes and tries to do something thereby causing a power-down.
I have found another thread in a different forum where somebody has the same problem with a X61:
http://forum.thinkpads.com/viewtopic.php?f=30&t=69643
Any help would be greatly appreciated, this is really annoying.

Prob while creating array in BPEL

Hi Folks,
I tried to create a string array in my BPEL to hold the values returned from my DB Adapter.
I created an element like the following in my "ArraySample.xsd" file.
<element name="myArr" type="xx"/>
 <complexType name="xx">
 <sequence>
 <element name="arr" type="xsd:string" maxOccurs="unbounded"/>
 </sequence>
 </complexType>
</element>
Is there any other place I have to create any supporting stuffs like part name.
Plss advise me. IF possible could any one give the step details of how to create an array in BPEL process.
Thanks
VP

Hi PS,
Plss refer only the bold letters of code, I'm able to append values to the array.
arr[] = {1,2,3}
While retrieving, for index 1 (arr[1]=123) it returns the entire value (appended value)
if I go for arr[2], its throwing error expression is empty.

Creating array descriptor

I need to create an array descriptor for a type that is defined in a package (Oracle 8.1.6).
If I define the type outside the package I can create the descriptor, otherwise I can't - even if I fully qualify the type with:
USER.PACKAGE.CUSTOMTYPE
or
PACKAGE.CUSTOMTYPE
The JDBC connection is created under the USER account.
Any ideea if this is a bug in JDBC or am I doing something wrong ?
Thanks,

IBook G4 makes the power-down noise while it's running

I know this is not a good sign and I'm guess that I'm at the early stages of HD failure, but thought it's worth checking. Here's the basic situation:
1. About two or three weeks ago, I noticed that after being idle for a while my computer would make a pinging noise--it's just like the sound you hear when you power down using the power button.
2. The computer didn't freeze or anything so I repaired permissions, verified the disk, had to do some Disk Utility repairs, and went on my merry way.
3. During the past 10 days I've gotten the folder with the flashing question mark and Finder icon a couple of times. The first time I was connected to the network at my office and my iBook booted from there. When I rebooted from the local HD it worked fine. Last night I heard the pinging sound, my computer froze and when I rebooted from my Leopard Disk and went to Disk Utility and the HD didn't appear in the Volumes window. I turned the computer off after this happened a couple more times. This morning I started up fine, was able to SELECT the Leopard DVD from System Preferences and run First Aid on my HD, but n the midst of that, the ping happened and I got the gray "You must restart!" box. Just did that and now my HD doesn't appear in as a disk, volume, or image option.
I'll try Single User Moder, PRam, etc. but I don't think that's the problem I'm having here. Help!

There are a couple of little utilities that can help you keep track of the inner workings of your hard drive and hopefully give you a heads up ahead of a failure:
S.M.A.R.T. Utility
http://www.versiontracker.com/dyn/moreinfo/macosx/32454
S.M.A.R.T. Reporter
http://www.corecode.at/smartreporter/
S.M.A.R.T. Utility can be downloaded and run several times for free. It will give you a more detailed look inside your hard drive than just "verified" or "failing". I think it tends to be a bit more critical than Disk Utility is. If you click on the "Show all" buttons, it will show you any errors on the drive.
S.M.A.R.T. Reporter installs an icon on your menu bar that is green when S.M.A.R.T. status is verified and red when it is not. It's intended to give you a heads up if your drive starts to fail.
Even though all seems well now, I'm not sure your hard drive is really to be trusted, especially if it is getting long in the tooth. It may well work for a while longer, but you might want to monitor how many errors it has and definitely keep everything well backed up.
It could be that your drive is starting to have intermittent mechanical problems, and this is something that Disk Warrior cannot fix. Intermittent problems can come and go and never seem to happen at the shop when you take it in. But if you find anything of concern in S.M.A.R.T. Utility, that would be something more concrete to go on. But as long as you keep everything backed up, there's no reason not to continue using the drive until it goes south for sure.
Good luck!

My desktop (M73 SFF) keeps power down and restart while playing games

I bought M73 small form factor with Intel core i5-4570 and 4GB RAM with integrated video in Sep. 2014.
Recently, it keeps being shut down while playing game (starcraft 2).
Is this related to hit sink issue? graphic? or both?
How do I fix this problem? Should I replace hardware?
Thanks!

Probably heat related. You can monitor the temps using Hwmonitor or SpeedFan. Your BIOS may have a fan setting, that you can adjust for better cooling performance (acoustic performance is the default.) And check that your BIOS and drivers are up to date, using Lenovo System Update, including the optional ones.

After reading and resetting everything with Keyboard I still get blank white screen. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans at full speed.

After reading and resetting everything with Keyboard I still get blank white screen on 2nd? page of boot. The only way I can boot to Mavericks is unplug power cord, push and hold power button while plugging power cord in. Fans run at full speed, machine boots then runs normal except the dvdrw will not . The mid 2011 IMAC had the same problem with LION. I changed hard drives, formatted, and installed a clean install of latest os x mavericks. Any help would be greatly appreciated.

Use the uninstaller provided with the Sophos software. You can uninstall CUDA via the preference pane. Be sure you remove the com.nvidia.CUDA extension which is located in the /System/Library/Extensions/ folder. Not sure if Fan Control has an uninstaller so you will have to do it manually:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
 1. AppZapper
 2. AppDelete
 3. Automaton
 4. Hazel
 5. AppCleaner
 6. CleanApp
 7. iTrash
 8. Amnesia
 9. Uninstaller
10. Spring Cleaning
For more information visit The XLab FAQs and read the FAQ on removing software.
Be sure to remove your two Login Items. Finally do this:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Lion, Mountain Lion, or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
 Note: You will need an active Internet connection. I suggest using Ethernet

I have been trying to use time machine on a new lacie 2tb usb 2 drive for back up. I continue to get: "unable to complete backup.An error occured while creating backup folder". When I use disk utility to repair I get another error message: unable to repair disk unmountable.
Help me Obie One Canobie you are my last hope

I have confused myself with the facts! Started out keeping track of every step and every variable but have sort of lost it as we progress here. First I quit all applications then swapped connections between mouse port and backup disk port to influence possible bad connections question. Changed power outlet receptacle for the backup disk. Disabled the put-the-HD-to-sleep option. Then powered down the computerator.
Next started up computerator. Turned Time Machine ON and experienced multiple successful backups! Then I started up a few applications, Mail and Text Edit (but not Safari so far). Had a few more successes. After each backup, I used Disk Utility to verify the backup disk is still OK. This because the error about unable to unmount the backup disk seems to go hand in hand with Disk Utility finding the backup disk to be bad.
Put computer to sleep for the night. Upon starting up in the morning, and before doing anything else, I did a backup disk verification... BAD! Did a restart and verified the backup disk... OK.
Did a few Sleep-bad, Restart -OK repetitions.
It seems consistent: Sleeping the computer apparently messes up the backup disk but doing a Restart "repairs" it.
=============================
Now then, I don't understand everything I know here. Methinks that maybe keeping the HD from sleeping during lulls in activity has allowed successful backups through the day but manually putting everything to sleep for the night causes a return to the problem of spinning-back-up-too-slowly (which was explained earlier). Is there any truth in this?
I may abandon this Seagate thing for something more compatible. What's out there that we know works reliably for us?

After a power failure while iPhoto was running, I get the message "Your photo library is either in use by another application or has become unreadable" and iPhoto will not open????

After a power failure while iPhoto was running, I get the message "Your photo library is either in use by another application or has become unreadable" and iPhoto will not open???? held down the option and the command and tried to run what was ticked off and it just sits there with a spinning wheel and does nothing, can I throw the app away and download a new one? or will it still not open?

, can I throw the app away and download a new one? or will it still not open?
You could, but the error message is indicating that your iPhoto library needs repairing.
Check, if iPhoto will run, if you launch it on a new library. Hold down the alt/option key, while you launch iPhoto. Select to create a new library from the panel that will show. Can you create a new library? If yes, try again to fix the library. Which options have you tried from the Library First Aid panel, when you launched iPhoto with the option and command key held down?
If you have not tried "Rebuild"; do that next. But be sure to make a backup of your iPhoto library, before you try this.

"error occurred while creating the backup folder" (-50)

Symptoms:
Bare HDD (Hitachi 1TB). When run on a simple cable setup, no issues. Recently got a Thermaltake BlacX dock, which is more convenient. First and more backup of any given session goes fine, then at some point, the error occurs, after which I can't unmount the drive without forcing it. After I force-eject, I can then reconnect the drive and backups will be fine again.
It may, although I'm not sure of this, occur when I leave the machine to sleep with the drive attached.
This implies that something between Time Machine, OSX and the BlacX are unhappy. Repair and reset haven't helped. Thoughts? I can always go back to using the cable, it was just a pain to set up, so I did backups less frequently, which is bad for me.
The Time Machine error is:
Unable to complete backup. An error occurred while creating the backup folder.
Latest successful backup: 10-09-13 at 1:47 PM

G'day all. Partner has an iMac 21.5 with Intel processor. OSX 10.6.4
Interestingly, we also have the exact same problem with a different brand external hardware RAID 1 as follows:
Welland Terra ME-580J fitted with two Samsung 1.5TB SATAII 3.5" 32M HD154UI drives.
The Welland site [http://www.welland.com.tw/html/2bay/580j.html] info is pretty brief but it DOES show Mac/PC in its brochure.
Connected via USB2.
From new we had to go through the initialisation stuff and had lots of hair pulling moments. Basically the RAID1 drive needed to be partitioned.
As with Geoffrey, TM did an initial full back up, then went OK for a few hours, then TM started giving the error message "error occurred while creating the backup folder".
Additionally any repair attempts via Disk Utility failed because the TM (Raid1 drive) couldn't be unmounted.
ALL apps were shut down leaving only Finder. Still couldn't unmount ext HDD. Kept getting the message that an app may be using the drive, etc.
Forced demount. Unplugged USB, turned power off to Welland and re-arranged the drives to be two independent drives.
Re powered the Welland, re-connected by USB, and there were TWO drives shown as "Time Machine" except one had the TM icon, the other a standard USB icon. This is exactly as I would have expected seeing as RAID1 disks have identical data on each.
RE-partitioned the USB drive to a) remove all data and b) change its name to avoid confusion.
TM now seems happy. I'm NOT happy, however, as this completely negates the whole idea of having back-ups to a RAID1 set-up.
It would be easy to suggest there is a problem within iMac/OS X, as two people having exactly the same problems with completely different hardware is just too much of a co-incidence.
Any thoughts and help would be truly appreciated, as I'm at the end of my limits, here.
With thanks, Ian.
PS please be kind to me, as I haven't gained a lot of Mac knowledge yet!
