Multithreading works only with the direct path load

Oracle DB version: Oracle Database 11 g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production

I'm on my way live load to load data from a flat file into a table using SQL * Loader. I also kept as parallel. However, I can't in multithreading is used at all, based on the report of the log file.

I use the settings according to the true value in the sqlldr: -.

parallel=true , multithreading=true , skip_index_maintenance=true

Output in the journal sqlldr:-

Path used: Direct Insert option in effect for this table: APPEND

Trigger DEV."R_TM_BK_BORROWER" was disabled before the load.

DEV."R_TM_BK_BORROWER" was re-enabled.

The following index(es) on table "YO"."TM_BK_BORROWER" were processed:

index DEV.I_NK_TM_BK_BORR_1 loaded successfully with 1554238 keys

index DEV.I_NK_TM_BK_BORR_2 loaded successfully with 1554238 keys

index DEV.I_NK_TM_BK_BORR_3 loaded successfully with 1554238 keys

index DEV.I_NK_TM_BK_BORR_31 loaded successfully with 1554238 keys

 

Bind array size not used in direct path.

Column array rows : 5000

Stream buffer bytes: 256000

Read buffer bytes: 1048576


Total logical records skipped: 1

Total logical records read: 1554241

Total logical records rejected: 48

Total logical records discarded: 2

Total stream buffers loaded by SQL*Loader main thread: 7695

Total stream buffers loaded by SQL*Loader load thread: 0

So, I can still see the newspaper sqlldr that all data flow buffers loaded by the main thread and load wire is not always used.

SQL * Loader load wire do not unload the SQL * Loader main thread. If the load wire supports the current stream buffers, then it allows the primary thread to build the buffer to the next stream while the thread of load load the current stream to the server. We have a server CPU 24.

I'm not able to find a clue on Google too. Any help is appreciated.

  • showacls works only with the unc on windows 2008 servers paths

    Hi people!

    We use the command showAcls.exe to the folder list ntfs permissions (we then use this list for some internal processes).  It worked well UNTIL we have upgraded a server to Windows 2008.  When we have a command like:

    showacls \\fs05\Userhome_45\brian-ba

    It returns nothing. No error, no data, just returns to the command prompt.   Needless to say that this command worked fine until the \\fs05 server has been upgraded.  I have found that if:

    I put a copy of showAcls.exe on the \\fs05 server and remote control and then in the server AND reference the full physical path, it will work.

    rcmd \\fs05 s:\showacls "s:\HO_USR1\User_Data_Processing\Userhome_45\brian-ba" / s

    Everyone knows this? Or am I the only one still using showAcls.exe?

    Would love to hear of a workaround

    Thank you!

  • GPIB analyzer works only with the Trace of e/s on the same computer

    Following the advice on the basics of knowledge I want to capture Trace IO simultaneously with the

    Capture on the field PC Analyzer.  This is because I have to go on a customer site and only want to

    capture non-intrusive traffic GPIB.  The IO Trace does not capture the field of PC that has the GPIB +.

    card.  When I run IO path on the Test PC, it works fine.  However, I want to avoid encroaching on the

    Setting up clients to say IO Trace Facility.

    If I run a basic series write and read VI. EXE on the PC in the field and to perform only IO capture of this

    works fine (no instrument not attached - just to make sure IO Trace works on PCs in the field).  If I run the NOR

    draw on its own on the field PC, then run the Test PC controlling Instruments, IO Trace is

    does not work.

    At this point, I wonder if Analyzer and IO Trace can not run simultaneously on the same PC?

    OR Trace does not work with GPIB cards +?

    Help much appreciated.  Thank you

    Trace of e/s OR and GPIB Analyzer can be run on the same computer, but not in the way you want.

    The GPIB analyzer is actually a Logic Analyzer, which "listens" for all lines GPIB directly from hardware. For this reason, it can be run from any computer connected to your GPIB topology, even it is not involved in the transers. This allows almost completely corner the bus logging.

    Trace IO OR works with drivers OR Save function calls that are made. These function calls can only be captured the system where they are called, therefore NO IO Trace should run on the test computer. Trace IO NOR will always be a small impact on the time where the test system, due to the time it takes to connect to each call.

  • HP Touchpad browser works only with the Cisco Valet Plus router

    I bought a 16 GB HP Touchpad several months ago and had been enjoying his excellent WiFi feature with my old G from Linksys WRT54GS wireless router until I replaced it with a new Cisco Valet Plus (model M20) wireless-N Router a couple of days.

    Although I could easily and successfully, join the Touchpad to the Cisco Valet network, browser fails most of the time to load web pages.   For example, if I go to www.yahoo.com, the browser is going to slowly load the web page, or it will expire with a pop-up message error "Impossible to load the Page.   If I try to select a link from the homepage of Yahoo, it expires with the same message.  And this happens for all web pages.  If the initial page happens at all, I can then from this page a link to any other.

    I know that the issue is not with the router because I have several other devices connected to it and they are all working well, including a laptop HP ProBook, an iPad and a Wii Console, I use to watch Netflix movies on.  None of them has a problem - only the Touchpad.

    If I go into settings-> Wi - Fi, it shows that the Touchpad is connected to Cisco network.  And when I run the diagnostic system, it shows that the Wi - Fi works correctly.

    Does anyone have an idea how to solve this problem?

    I have found a workaround that did the trick.  I had to change the channel setting auto on a coded hard 1 channel wireless.

    Now, the Touchpad works very well, as well as all other devices that have worked.

  • My Wacom Graphire4 graphics tablet works only with the pen pressure, OK in CS5 but not CS6...

    I am Windows 7 Professional 64 bit and still have the CS5 and CS6 64 bits loaded.  I've used my tablet with stylus Graphire4 with CS6 will detect all problems.  All of a sudden it only works with the pen pressure even if the stylus pressure is off.  I'm trying to use it as a mouse and frequently use shift/click when you change a mask.  I can do it no longer.  If I run CS5 the pen works as it should but not CS6.  When I first open the CS6 with visible brush the brush palette shows a hard brush, but when I open a file it turns into sensitive pressure without measure by me.  I have reset the brushes, re-installed the driver and finally downloaded a driver more but the problem persists.  Because it works very well in CS5 but not CS6 it must be a problem to Adobe.  It's very frustrating.  I enclose a composite image showing what happens to the CS6.  The right side shows what looks like the brush palette until I open a file.  The left side shows what happens when I open a file.   Even if I do not open a file and make changes within the brush palette, it immediately turns to pen pressure.  It's very strange.

    I would of course someone can provide information that could help.

    Kind regards... Ralph

    brush_palette.jpg

    No answers, but in the meantime, I have come into contact with Adobe.  Problem has been resolved by phone.  Resolution is to delete the preferences file reopen CS6, date at which the PS automatically creates a new preferences file.  It was she, corrected a problem... Ralph

  • Magic Mouse works only with the latest el capitan

    Why Apple is not the problems with El Capitan (10.11.6) and it's Magic Mouse? The only way is connected to my MacBook Pro is to remove the com.app.bluetooth.plist at the end of each session and even that does not always work. When it is finally connected, the mouse connects and reconnects constantly during the session. The mouse is an Apple product, and Apple does not seem to recognize the problem or give anyone a viable solution.

    Determine that the problem is inherent in the software is an act of faith (there is no batches of messages here with the same problem).

    Try resetting the SMC and the NVRAM.

  • Samsung 850 EVO Solid State Drive works only with the MacBook Pro - Solution?

    I recently bought a Samsung 850 EVO 500 GB Solid State Drive for mid 2012 MacBook Pro father. The computer was working properly, but it was just very slow. I took the old drive and installed the SSD. I took it to an Apple store so that they could install the OS. A guy at the Genius Bar met with me and first tried to install the OS via the Ethernet cable. It is impossible to install some general error. He then tried to install it on a disc. Which also failed. He said he was not familiar with the type of error that he saw. But he said it was a mistake 'bad '. He said he saw the SSD for my SATA cable worked. He concluded that the reader must be defective. I explained how it is virtually impossible because they have a rate of close to zero. He said: "well they are produced en masse" and explained how they could install a hard drive themselves for some too expensive price. A bit annoying.

    In any case, I took the SSD back to my house and threw it in my desktop PC. It works very well. Then what should I do? Why am I not able to get the SSD to install it? From what I read, the Samsung 850 EVO should be compatible with a MacBook Pro 2012. Can I do to install it at home? Is that all I can say people at the Mac store to help them along?

    Most likely, the drive is formatted for use with Windows computers. First step would be to format correctly for Macs.

    This is Mac OS extended (journaled) with a GUID partition map.

    OS X will only be installed on a properly formatted disk.

  • printer scan works only with the new windows 7

    upgrade windows xp to windows 7 with the new HP Omni 220PC. Have a printer HP C309g-m. To scan from the printer to the computer xp, I had to use the HP Solution Center. The printer works very well with the new windows 7 program and new computer. I install wireless. No problems with it. Today when I went to scan a document with the HP Solution Center (I thought I had to use as before), this message came.

    "HP Solution Center cannot work because your device installation is not complete. Please connect the usb cable, or rerun the installation for a network installation cd. If it does not complete the installation, or you do not have the cd, access the HP help files by clicking on the start menu. "Everything I did. My installation CD said I had a version of the latest update on the installation CD, it was of no use. I went to the HP site and find a download for the drivers updated etc. I downloaded and installed. (although I don't know whether or not it was a duplicate of the drivers of devices on windows 7 for this.) I checked Add/Remove programs to make sure that the printer and the hp solultion Center have been added to the programs. they are listed. I can always scan with

    the hp Solution Center. Should I not this program to scan with this new pc? How can I scan from my printer now? I even tried to click scan on the printer, then scan to computer. the message I got was 'Try from scan of compurer. Refer to the documentation for more details ".  To be sure, I'm all mixed up now. All I want is for my scan printer to work with my new pc.  Everything works well except that scan thing, may help me understand what to do?:  Thank you

    all fixed. has crossed my computer to start then click HP click HP and open list. Went to my printer-clicked on my printer and clicked on the icon list to see if it worked correctly. This is a problem with the drivers and a box popped up with directions on where and how to download and install the devices for windows 7.
    Done this and tested it and everything works fine now. (Ihad already tried the HP site for support and downloaded and installed the fix suggested for the problem, but it did not work). in any case, its fixed and I hope that if someone has a problem, this information will help you.

  • RV220W works only with the PPTP server on one VLAN only

    Hello

    I have a RV220W (firmware 1.0.3.5) but I can't seem to work with the PPTP server on one VLAN only.

    My default VLAN is in 192.168.1.1/24.

    I created a VLAN ID 10 in 192.168.50.1/24 inter - vlan routing: disabled and device management: disabled.

    (Menu network > LAN > belonging to a VLAN and multiple VIRTUAL local network subnets).

    Then I configured a PPTP server on the IP 192.168.50.200 to 192.168.50.210 range.

    Finally, I created my user.

    (Menu VPN > IPSEC > VPN users).

    The PPTP tunnel is at work, but on all of my local network and not only the VLAN ID 10.

    Any idea? ...

    This seems to be a limitation of the firmware 1.0.3.5. Firmware 1.0.4.x will support the rules on access inter - VLAN, which I hope, can be used to restrict traffic VLAN by default your VLAN ID 10.

    If you want you can import the Boot Camp partition as a Virtual Machine based on a separate stand alone file, or you can install Windows from scratch.  After you import if desired you choose and you don't want to use Boot Camp natively or as a training Camp for the virtual partition Machine (not that any) and want to recover the space that the Boot Camp partition is far from taking the Macintosh HD you can then use the Boot Camp Assistant (/ applications/utilities/Assistant Boot Camp) to remove the Boot Camp partition to reclaim that space.

    For the import of the Boot Camp partition as a Virtual Machine based on a stand-alone file, take a look at: VMware Fusion (menu bar) > help > VMware Fusion help > creating virtual machines > import Virtual Machines > import the Partition Boot Camp

    Regarding the Boot Camp existing partition Virtual Machine...

    Note: These senses are different which have already been posted so read and follow through... Note: These steps assume that you have a single Apple to default installation of Windows on a single Boot Camp partition and Boot Camp of VMware Fusion single default partition Machine virtual (without a snapshot *) and if you have changed the partition Boot Camp Virtual Machine to add additional hard disks to be virtual or RAW disk then do not use these instructions unless you backup the Boot Camp partition the Machine package virtual first. * Also note that Fusion 2.0.0 may accidentally have a snapshot with the virtual partition Boot Camp Machine and it should not have, then you should check to ensure that the condition does not exist as well. (With merger closed if the partition Boot Camp Virtual Machine package is over 1 MB in size, then you might have a snapshot in place and do not continue with these instructions.)

    ===

    1. If the merger is open, close it.

    2. in a Terminal (/ Applications/Utilities/Terminal) copy and paste command, as the following and then press Enter and it will delete the partition Boot Camp Virtual Machine of the metadata and the Virtual Machine to help.

    Note: This does not affect the Boot Camp partition install windows in that it does not remove it.  Also be sure you copy all the command line below, as well as, "RM" at the beginning of the ' (quote) after the s in the Machines. "

    RM - dfr "/Users/$ the specified item was not found./Library/Application Support/VMware Fusion/Virtual Machines.

    3. start Fusion (/ Applications/VMware Fusion) and select the Boot Camp partition on the window library of Virtual Machine, and then ctrl-click it and select Delete.

  • TMSPrint works only with the Web Player

    I use TMSprint for all the impressions of my piece which works fine on the desktop. However, when you try to access the print function via the web player, I get a "TMsMPrint" module not found. All modules are loaded. I suspect that the tms_mp.dll module that seems to lead the process is the culprit - although I've had my ISP add the .dll type other than the reader needs, this doesn't work. It seems that TMSprint will not work on the web. Is this true?

    If so are there any alternatives that will work, for example Printomatic?

    With the help of your files and my localhost, I was able to understand the problem. He was not mprint.x32 this file is not required (it is an earlier version of MPrint). The problem was the line in the .aam that reads set DOWNLOAD. The "update" command actually did a directory change. All files listed after that it will go into the download folder until it reaches put an another command. You can see the dowload file if you open the web drive location while the piece is still ongoing in your browser, this is a temporary file that is deleted by the runtime during the shutdown. If you remove this line from the aam file then the file tms_mp.dll will in the right folder and it will work.

  • IMessage works only with the last update in elcappitan

    Why not send iMessages on my iMac since the upgrade to the latest version of El Capitan?

    Hey lahugus,

    I use iMessage every day and if it stopped working for me all of a sudden I wouldn't be happy.

    I would first double check the messages preferences and check iMessage is enabled and that you are connected with the correct ID of Apple.

    If that is correct, turn off the computer, and then turn it back on and test again.

    If it does not sign iMessage and then again in it.

    These steps should solve your problem.

    See you soon
