Cube DTP load runs forever but doesn't do anything

Hi experts.
I was hoping to get some guidance on an issue I'm having loading one of my cubes.  I've searched the forums but can't seem to phrase the search correctly because I'm not getting any results.  I'm on BW 7.x.  Here is the data flow and scenario:
APO Datasource A --> BW Cube A --> DTP --> BW Cube C
APO Datasource B --> BW Cube B --> DTP --> BW Cube C
This is a monthly load that has been in place for several years with no previous issues.  Yesterday everything went fine up until the load from
BW Cube B --> BW Cube C.  This DTP normally runs about 10-15 minutes.  But yesterday I tried running it twice, once for two hours, and once for 4.5 hours, and never got a single record to load in the target cube.  It just kept showing "0 Data Records" under the Process Request section.  The load never completed and never erred.  I eventually cancelled both runs manually.  Neither SM21 nor ST22 indicated any problems.  I checked with my Basis guy and he did not see any issues on the Oracle side.
Now, Cube B is the largest cube in my BW at around 48 GB, but I've never had problems with this load before.  Between the first and second attempt I dropped and rebuilt the indexes and verified statistics.  But I don't know what to fix because I can't find any errors.
Points will be awared to anyone with viable suggestions or direction to a solution.
Thanks in advance.

Hi,
During your load time, Is any new loads/full loads are scheduled at bw prod?
There might be something scheduled on that day. you need to track the whole loads scheduled in that time frame. you may find if any changes on scheduling loads other than usual.
before loading data to cube, have deleted the index?
Can you check dtp monitor logs in detailed?
During your load have you checked SM51 whether free application servers available to process your load?
Thanks

  • Downloads such as adobe flash update won't download even when anti virus is disabled. The download box appears and runs but doesn't show anything.

    Any updates or downloads won't download in Firefox. The download box appears, goes thru the motions but doesn't park anything in the file. I usually have to quite Mozilla, use Explorer for the download, such as Go to Meeting, or Adobe updates. Can't download anything with Firefox from your browser.

  • My iPod syncs, but doesn't save ANYTHING on the iPod

    Basically, my iPod syncs, but doesn't save ANYTHING on the iPod, its the first iPod I have used and it really annoys me... I have tried pretty much everything :@
    Help?!

    Hello JellyPopJade,
    And welcome to Apple Discussions!
    How do you have your iPod configured to sync with your iTunes library? Automatically or do you manually manage its contents by dragging what you would like from your library to the iPod.
    If you have it set to automatically sync all checked songs and videos, make sure each track you wish to sync to your iPod is checked within your iTunes library.
    Under the Summary tab for your iPod, is there any space taken of by the "Other" category (orange)?

  • Why displaying cube 0PUR_C01 content runs forever?

    We conducted data load to 0PUR_C01 through two different datasources 2LIS_02_ITM and 2LIS_02_SCL.  Check the cube, find the initial request for 2LIS_02_ITM did add 1648 records, but when we try to display this cube content by only selecting a few fields for selections like Company Code, Purchasing doc category, and etc., and take the default Max no. of hits of 200, but when hit the execute button to try to display the cube content, find it always runs forever at the selection screen with going no where!
    Any reason?
    Thanks

    Kevin,
         I never had this problem, while displaying the data. better check with your basis, they can help who is working on the system they can guide you. If you do RSRV tests in the parrllel it will take time.
    I'm thinking, some of your colleague is doing some thing at that time. Check with your basis.
    All the best.

  • SQL*Loader running forever

    Hello,
    I am using Oracle 10.2.0.4 on RHEL 4u4. I am trying to load a table with data using "Load Data from User Files" in Enterprise Manager (SQL*Loader).
    When I run the job, it just runs forever and never finishes. I am only trying to load about 6,400 rows, so I can't imagine it should take very long. I have created a .BAD file, a .DISCARD file, and a .LOG file, but all are empty. I have also been monitoring the alert log, but I don't see anything pertaining to the load in there either. Perhaps I have something incorrect in the control file??
    Here's a sample of my data in the flat file:
    1*"LAURA,LORA,LAURIE,LAURI,LARA"*
    2*"SARA,SARAH"*
    3*"JENNIFER,JENN,JEN,JENNI,JENNY"*
    And the control file generated by Enterprise Manager:
    LOAD DATA
    APPEND
    INTO TABLE NAMES.NAME_VARIANTS
    FIELDS TERMINATED BY '*' OPTIONALLY ENCLOSED BY '"'
    COUNTER INTEGER EXTERNAL,
    VARIANT_TEXT CHAR
    I am unsure how to troubleshoot this as I am getting nothing in either log file!
    Mimi

    Update. I tried running the control file manually using sqlldr at the command line and it worked just fine. Not sure why scheduling the job through Enterprise Manager didn't work for me. Anyways, problem resolved!

  • MSI 970a-g46 motherboard starts up but doesn't display anything.

    Hello, I'm having problems with a new motherboard I got from Amazon, specifically the 970a-g46. The following are my specs in use with this motherboard:
    CPU: AMD Phenom 2 x4 965
    GPU: nVidia GeForce 560 GTX
    Ram: 8gb Kingston HyperX Fury 1866mhz.
    PSU: Corsair 650TX (650 Watts)
    Compatability-wise, everything checks out so I wasn't expecting problems at first. All the other parts excluding the ram I've used before. Here's exactly what happens:
    I power up the computer after everything is installed and connected. The 4 phase LEDs turn on which tell me the CPU is powered up and working (so I assume). I don't get any beeps or buzzs mainly because I don't see any speaker/buzzer on this board. The monitor blinks and while it is connected to my GPU, it doesn't display anything, it's just a black screen. I can leave it on for a few minutes and I'll still not see anything happen. An important observation here is that my keyboard which has LEDs will turn on after a short period of time in boot-up (with my older set-up that is). This does not happen ever regardless of how long I leave my computer on on this new mobo.
    I've gone over and checked/tested numerous things:
    * The PCI-E and ATX cables for the GPU, motherboard and CPU are all connected and secured (I've tried both 4-pin and 8-pin connections for the CPU, neither help).
    * I've tried jumping the CMOS multiple times to no avail.
    * I tested the ram on another computer and it worked just fine on that one.
    * I've tested the motherboard without a GPU and it still does nothing (though I think that's because this motherboard doesnt have its own integrated GPU for some reason).
    So far the only possible reasons why my computer is not working is because of my PSU (very unlikely as it's only a year old and it's a Corsair, which I've heard is very reliable in the long-run), GPU (It is quite a few years old but even without the GPU my computer still doesn't go past boot-up), CPU (possible due to its age and how many freaking time I've reseated it (probably around 8 times) so I wouldn't doubt it, but before I put it into this motherboard I did check its pins and they were all there and placed nice and smoothly into the socket.) and finally the motherboard (it's possible that this is just a defected motherboard and giving me a super hard time which would be a first in all the years I"ve spent computer building).
    The best case scenario of course is me giving some kind of oversight to how I transferred over the parts and connectors. I might've missed something obvious to please any advice/insight on how I can solve this problem would be greatly appreciated
    EDIT: Some other things I did but forgot to mention:
    * Checked ground nut things and ensured they matched the specifications of the motherboard ATX; only 6 are under the board and each one is aligned up with the holes on the board as designed.
    * Tried booting up without powering the CPU. Only one phase LED light came on, still the same problem (for an obvious reason this time now).
    * Re-seated GPU multiple times, re-connected cables multiple times.
    What I have NOT done is re-seat the CPU because I am almost out of acetone so I would need to get another supply of that which won't be until tomorrow. I also have not re-seated everything back on my older motherboard to check if it still works. Tomorrow I'll most likely do that and if I find that the old motherboard works flawlessly then that tells me that the new motherboard I got is either defected or there's some compatability issue I"m missed out on.
    EDIT 2: Just found a speaker and plugged it into the motherboard. Booted it up and I got no beeps whatsoever. So this mobo is giving me no video activity (there is a signal it's just blank), and no beeps from the motherboard. I have no idea what that could mean at this point.
    EDIT 3: I decided to test a few things with the new speaker I just got. First I removed ram and tried running, I got 3 beeps which I assume is the beep sequence of faulty/no ram. Removed the power to CPU and the GPU itself individually, gave no beeps this time.

    What's the serial number of your MB? Needed to determine what BIOS may be on the MB. Exactly which version of the CPU is it? There were several different 965 CPUs and they required different BIOS versions, 1.2, 1.9,2.2 depending on which CPU you actually have.
     Also another problem may be that native memory supported by your CPU is DDR3-1333, not 1866
     None of the supported CPUs have integrated graphics, any MB graphics would be in the chipset, not CPU. Examples would be 785G, 880G
    Thank you very much rhradacut! The problem was that the mobo for whatever reason was forcing 1866mhz on my CPU when it only supported up to 1600mhz. I had to install a spare ddr3 module to downclock it so that I could access the BIOS and manually set the DRAM timing to 1600mhz for it to work. That's a very strange problem that I figured would've been auto-resolved by the hardware, and would also be a big problem if I didn't have any spare DDR3 ram to work with.
    Once again thanks for helping out on solving my problem.

  • Mini Bridge in CS5.5 opens but doesn't do anything

    I am running CS5.5 on a MacBookPro. When I try to use Mini Bridge the little gray panel opens up but there is no "browse files" button, I can't open settings, I can't search, I can't do anything with it! Bridge works works just fine. I am including a screen shot of my MB window to show what I am seeing. I have tried everything I could think of including restarting Bridge and PS. Is there something else I need to try other than a complete reinstall of the App, which I will not do just to get MB to work.
    Thanks for any and all suggestions.

    I'm back to this discussion because I have never solved the problem. Today I uninstalled and reinstalled PS. I trashed preferences, checked to make sure Switchboard was working (it is), and have decided that my mini bridge extension is broken. Any place I can go to download a fresh copy? The window is dead. Even the settings selection doesn't bring anything up.
    Thanks.

  • Preview launch but doesn't display anything

    Well, everything was running (nearly), but since this morning when I want to view an image or a pdf, preview opens but does not show me the pdf or picture.
    Iv' tried opening preview and than do file-open file, but I just got the same result.
    any clues.
    PS: the "nearly" is about an unresolved issue where very frequenly the macbook pro want shut down properly. It looks like it off, but it's not and it won't "wake". The only way I've found to get out of this "nearly off" state is to manually shut it down by pressing the power button for a few sec. Than it boot, but display a message saying that mac os didn't close properly...

    Log back into your problem account:
    Here's the whole litany for thoroughly checking your home folder. It's not as daunting as it looks.
    1. Navigate to ~(YourHome/Library/Fonts - drag this folder to the desktop.
    • Restart and test your applications.
    • If they work start adding the fonts back few at a time.
    ( Likely suspects are Times RO, Helvetica Fractions and Times Phonetic, also if you do not use Classic you can trash the classic fonts.) If not, replace your Fonts folder.
    2. Check Preferences Thoroughly;
    • Navigate to ~(YourHome/Library/Preferences drag this folder to the desktop.
    • Restart and test your applications.
    • If this works, save the old preferences folder somewhere else or on disk, name it "old prefs" .
    ** Note: A very important file is the "com.apple.Mail.plist" preference file located in the Preferences folder which contains all email account settings and general mail preferences (hold this one and replace if your problem is not with Mail).
    You'll have to go through some of your System Preferences and apps to set the preferences back to how you like them. (Or if you have the time and inclination, "cherry pick" through until you find the problem one or two.)
    3. Check Permissions Inside Home Folder
    • Navigate to YourHome/Library.
    • Get Info (Command - i) on folders for apps you are having problems with.
    • Open the "Ownership & permissions" disclosure triangle.
    • Make sure you are the owner, with "read and write" access.
    • Click on "apply to all"
    • If this is correct, open the "Applications Support" folder and do the same procedure (Command+I) for the folders with the names of the applications you are having trouble with.
    (Note:The reason to check this is because repairing permissions with Disk Utility doesn't touch permissions inside your home folder.)
    4. Navigate to YourHome/Library/Caches and drag this folder to the trash, then log out and back or restart. There is no need to replace this folder.

  • My Time Machine also runs "successfully" but doesn't back up anything.

    I know on page 2 that this problem was already posted and solved, but it looked like the person didn't have Time Machine on or something like that. Can someone please give me a quick run down into why this is happening and how to fix it?
    Thanks,
    Chuck

    Obviously I need help with why Time Machine is not backing anything up and not with why the Time Machine button doesn't work.
    Thanks (again),

  • PPTP ip-up.d runs script but doesn't execute program

    Hi everybody
    I installed and configured PPTP and ip-up.d scripts. Everything seems to work, all three existing scripts are executed and also the echo is written to syslog but I don't get the program to start. If I execute the script manually it works like a charm.
    What is the matter?
    Solutions tried
    PATH definition added
    echo line before and after executing remmina added -> both worked
    changed program execution with "sudo -u <user> remmina" and "su <user> -c "remmina" etc. also not worked
    permissions checked, every script file is on 755
    #!/bin/sh
    PATH=$PATH:/usr/bin
    echo "`date +%b" "%e" "%H":"%M":"%S` PPTP: Remmina wird gestartet" >> /var/log/syslog.log
    /usr/bin/remmina

    Hi, sorry for late answers:
    ..scripts that end with '.sh'. Is that the case?
    [emak@PC-LE-T42-LI ip-up.d]$ ll
    insgesamt 20K
    drwxr-xr-x 2 root root 4.0K 20. Mär 13:40 ./
    drwxr-xr-x 5 root root 4.0K 6. Mär 07:16 ../
    -rwxr-xr-x 1 root root 229 3. Nov 2011 00-dns.sh*
    -rwxr-xr-x 1 root root 110 16. Mai 18:45 01-remmina.sh*
    -rwxr-xr-x 1 root root 162 20. Mär 13:23 02-routes.sh*
    They should be correct and permissions sufficient.
    Does remmina fork?
    No, I don't see any procs running by executing
    ps -ef | grep remmina
    Last question:
    you can execute it as a separate process by adding &!
    I tried that with no better success.
    As I wrote above, the script is executed, the echo line is written to syslog but no process of remmina is starting. I'm sure it's a dumb thing but still annoying... Any more ideas to try?

    When I am trying to test this checkbox in my application (in either debug mode or 'run' mode) an error is being thrown which I am not able to figure out why this error occurs (though I know its complaining about Null object reference). But when I am building the application with "Export Release Build" option and installing the application on my desktop to test the same checkbox - it works!! I am not sure why this is happening. Any help?
    Can you tell me why it's not complaining about Null object when I build the project or how to overcome this problem?
    This is the error:
    TypeError: Error #1009: Cannot access a property or method of a null object reference.

    Thanks in advance.

    Can you post the code at ComponentContainer.as line 48?
    Also, make sure the debug SWF is up to date; delete it in bin-debug, make a change to ensure the new one has come up.

  • My MacBook won't go passed a grey screen and the apple logo . It has a loading bar but doesn't do anything and just shuts down after the loading bar is complete... HELP!

    Please please help!  I'm a college student taking finals. Need it fixed asap

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 3
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 4
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 5
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 6
    Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 7
    Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 8
    Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 9
    Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
    Step 10
    This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 11
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Disk Utility verify or repair permission runs but doesn't indicate anything

    Recently I ran Disk Utility to repair permissions after a software upgrade and the utility ran and ran, but no permissions were repaired and the utility didn't stop running. After an hour, I stopped running repair permissions. Does this indicate something remiss about the utility? Or worse? What should I do about this?

    You might want to boot from your OS installer disk and launch Disk Utility. Repair Disk from there.
