DBMS_DATAPUMP with degree (parallel), causes worker run on wrong RAC node
Hi @ all,
I have a very very strange problem with DBMS_DATAPUMP :
- I have a procedure that export (every night) some objects from my database on a partition mounted only in the node 1 in +/exports+ mount point
- This Procedure is inside a job, inside a job group, inside a service that force this job to run ONLY on node 1 of my RAC (Enterprise 11.2) , and the service works fine:
#srvctl status service -d ORCL
Service EXPDPNODE01_SERVICE is running on instance(s) ORCL1- These objects are grown and the exp require too much time. I have introduced the parallelism
Now with parallelism enabled my problem is that the exp raise many ORA-31617 apparently for no reason but the problem seems described here: [ http://oraclehandson.wordpress.com/2012/07/17/oracle-11-2-datapump-ora-31617-ora-19505-ora-27037/] and I have confirmed this problem because i have found one Worker run on second node ...
With expdp (application) i can use option introduced in 11.2, cluster=N but i want to use DBMS_DATAPUMP ...
can you help me?
Edited by: iaio on 26-mar-2013 15.31
Works! Thank you ... I was reading 11.1 but in 11.2 oracle have added many additional parameters!!!
I have tested and works good! This is my (new) START_JOB :
DBMS_DATAPUMP.START_JOB (
HANDLE => HNDLR,
SKIP_CURRENT => 0,
ABORT_STEP => 0,
CLUSTER_OK => 0,
SERVICE_NAME => 'EXPDPNODE01_SERVICE'
);Thank you again!

I have a new Macbook pro and need to run some Windows software, it appears "Parallel" should work well from what I've have read. Will I have any issues or problems accessing and printing from various printers on my Windows 7 network within Parallel? Is Parallel in fact the best way to go?
First, back up all data immediately, as your boot drive might be failing.
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.

Hello
I have an I mac with Yosemite operating system.
I installed a windows seven 64 bit on it.
also i have a parallels desk top with version 10.
if i run my windows without parallels my windows and my office is activated ,but if i run my parallels then my windows and my office can not be activated .
My problem is activating my windows and office through parallels desktop .
i had installed windows an parallel desktop several times ,also i installed several times parallel tools with menu bar in parallels desk top and when i am installing parallels desktop tools in any way i can see the (CTRL+ALT )
all of my application in windows works properly through parallels desktop except
activation of office and windows .
I do not no any solution for my problem , i need for helps .thanksIt is not W10, it is the Technical Preview version of W10.
Search on the Windows forums (fora for the latinist) for activation in the TP W10. -
I have a desktop machine windows 7 based with CS5 loaded and working without problem. I have recently purchased a laptop running 8.1 windows. I have loaded the cs5 package onto the laptop and it appears to work but when I try to update, although I am being told there are updates it attempts to download the update but then tells me there is a problem and to quit and try again later.. I have tried a number of times to download the updates but itkeeps telling me to quit and try later. what is wrong please?
There could be a 32 bit vs 64 bit issues-is the old machine a 32 bit? and what is the new machine as far as 32/64 bit. I am not sure now if CS5 has in the help menu of the PS app the selection to update within PS if so that might work. I know that the Creative cloud app for installs updates etc has caused me much consternation over the last couple few years. Last it could be something like your Software firewall settings or anti-virus anti malware programs. I know that updating the infamous adobe flash that Internet Explorer pop ups setting and having AV turned on as opposed to off can interfere or plain break the update ability

DS 1.2 SDK extension component cause APS running with error
By following DS Administrator Guide Section 6.1.3, we are able to successfully deploy the extension to the BI platform (BO 4.1 SP2 version 14.1.2.1121) from the DS design tools.
However, after restarting Adaptive Processing Servers, it state become "Running with Errors".
By checking the properties, the error came from Analysis Application Service "Unable to initialize service. LogID:"
With this error, attempt to execute a simple DS analysis application (e.g. standard desktop blank template - blank page) on BI platform will result in error.
"A session with the Application Service could not be established."
The initial exception that caused the request to fail, was:
Analysis Applications enterprise client was unable to open the session: while trying to invoke the method com.sap.ip.bi.zen.boe.server.transport.corba.ZenServiceImpl.openSession(com.sap.ip.bi.zen.boe.transport.corba.CorbaLocale, java.lang.String, java.lang.String, com.crystaldecisions.thirdparty.org.omg.PortableServer.POA) of an object loaded from field com.sap.framework.services.zen.Zen.zenService of an object loaded from local variable 'this'

Uninstall the SDK extension and restart the APS will bring everything back to normal. Have tried others SDK extension package and all give the same problem.

with the latest IOS 7.0.3 for my iPhone, it no longer syncs with iTunes. I've run the diagnostics for syncing and it says everything is working, which it clearly isn't. Is there anything to be done without restoring iPhone? Thanks
update : so after reading numerous posts, I tried unchecking entire playlist and just tried one of my playlists. That sync seemed to work, so I rechecked entire playlist and did the sync. It worked. Then I went in to my "walk to work" playlist and added some songs to see if it would sync now, and it did!!! so happy now. will see what happens tomorrow.

Any tip as to how to change the apple id for icloud and any idea how to know what apps i bought with the other apple id so as to delete them from my ipad to avoid being asked to enter another apple id every time they get updated? thanks!

Hi I have just bought a mac book pro 2ghz 8gb ram with haswell.also it's running maverick. I am wanting to start using logic but does it work ok with maverick everything I read says it's no good please help
Which version of Logic? I have 9, but I've yet to install it. I'm just creating the images of the disks atm to install them on my Haswell. Will let you know how that performs.
Logic 10 would most certainly work fine though. -

I used to shoot video in my Powershot S3 IS (Format MVI_.AVI) and load them into iPhoto, I used quicktime pro so I could convert for emailing to family members. That was when I was running Leopard now with Mt. Lion nothing works. Videos do not open at all. Any simple suggestions, I am not real keen on iMovie Productions and not real certain how they compress for emailing attachments. Something simple here that I am missing? Thanks so much. I am a grandpa trying to share with family members far away (quickly & simply).
I am surprised that Apple did not build a converter into Mt. Lion.
Apple does have a converter built into Mountain Lion. It is call "Quicktime." However, in order to use this converter, you must first make sure the compression formats are playback compatible with QT. Basically, there are three levels of QT compatibility. The lowest is "Playback." These file can be played by QT but may not be conversion or edit compatible with QT. The second level is QT "Conversion" compatible. These files are playback compatible and can be converted to other compression formats using QT. "Edit" compatible media files are "Fully" compatible with QT since the can be played, converted and/or edited by QT. The main problem here is that AVI is a "legacy" file format that has not been officially supported by Microsoft for more than 11 years when it was replaced by Windows Media multimedia file/compression formats. Many of the original compression formats used in AVI files have never been transcoded for the Mac platform, use beyond system 9, or use beyond PPC platforms. In addition, some commonly used AVI codecs are proprietary or use non-standard (hybrid) profile and level combinations. In short, there is little wonder that Apple has been distancing itself from this outdated file type as it re-writes and upgrades its own QT structure to support more standardized, more scalable, more modern high definition file types and compression formats. It is really unfortunate that users continue to use this outmoded file type simply because it is freely available, easy to use, or they are simply too lazy to move on to a more modern or more efficient file types and/or compression formats.
I tested Wondershare Video Converter Ultimate for the Mac, which seems to be the "state of the art". I may be purchasing a new camera which might create a whole new set of variables. This program seems to cover all bases and is great for novices.
There are many third-party apps available if you wish to search for them. Many are even available in the App Store. Most do their job well and it is usually a matter of personal user preference as to which is best.
HandBrake seems more suited to folks with more experience and knowledge.
I mentioned Handbrake primarily because it is free and easy to use when you employ the included conversion presets options. (The TV options can normally be used for almost any situation depending on the source file and output requirements.) It is also excellent for more experienced users, but has a somewhat limited choice of output options as it does not access the user's system QT codec component configuration. -
Automatic Parallelism causes Merge statement to take longer.
We have a problem in a new project as part of the ETL load into the Oracle datawarehouse we perform a merge statement to update rows in a global temporary table then load
the results into a permanant table, when testing with automatic parallel execution enabled the plan changes and the merge never finishes and consumes vast amounts of resources.
The database version is:-
Database version :11.2.0.3
OS: redhat 64bit
three node rac 20 cores per node
when executing serially the query response is typically similar to the following:

I understand that the query is considered for parallel execution due to the estimated length of time it will run for and although the degree of parallleism seems excessive
it is the default maximum for the server configuration, what we are tryig to understand is which statistics could be inacurate or missing and could cause this kind of problem.
In this case we can add the no_parallel hint in the etl package as a workaround but would really liek to identify the root cause to avoid similar problems elsewhere.

Based on the discrepancy between the estimated number of rows and the actual, and the below posted bind value of 2012-04-25 i'd first be checking if the statistics on T_CACHARGES are up to date.
As a reference

So that would be my first avenue of exploration.

Failed to run parallel path when using call library function node in LV2009
I have a problem with two parallel paths not being run in parallel on LabView 2009.
See the image below.
This code initializes an external device, the upper part contains a call library function node to download my code into the device. When done, the function returns and the "Done" flag is set to True.
The lower part contains a call library function node to check the download status, reporting the percentage of downloaded code.
This updates a progress bar that is referenced by the calling VI module and this works fine in LV 7, 8 and 2011. The lower path of the VI updates the progress bar while the CLFN in the upper part is still downloading code to my device.
Somehow, in LV2009 this does not work when running this inside my application. When running just the calling VI (the window showing the progress bar) it works but not when that VI is called by my application.
Is there some limit on parallel threads that is different in 2009 than in other versions ?
Or is there some other problem in 2009 that might cause this problem ?
My labview version is 9.0f3 (32-bit).
Regards,
RobI've just installed the DETT tool and checked what the different versions of LabView do.
In LV2009 the application instance runs in a thread (5) but the modal dialog (the VI above) then drops to thread 0 and stays in thread 0.
In LV2011, stays in the same thread as the application instance and only a trigger event (this could be the progress bar reference?) is executed in thread 0.
So it seems there is a 'feature' in LV2009 where modal dialogs are by default not following the preferred execution system set in the VI properties ...
When I change this from "same as caller" into another thread (I used "other 1") then my progress bar works as expected.
I'm not a LabView thread expert (not even a novice ) so I'm just guessing that "other 1" as a thread is OK. This VI only runs during startup of the application to download the code to my device.
To answer Ben's question: "What thread does a modal VI run in?":
In LV2009, the modal VI runs in thread 0 (UI thread ?). When the preferred execution system is set to another thread, the modal dialog still starts in thread 0 but then switches over to the other thread.
In LV2011, the model VI runs in the caller's thread (preferred execution system set to "follow caller") from start.
Thanks,

A problem with this webpage caused Internet Explorer (IE9) to close and reopen the tab
I have IE9 (using 32-bit version) installed on a relatively new laptop with Windows 7 64-bit. Up until last weekend IE9 worked fine and Flash Player worked fine too.
At the weekend a webpage asked for Flash Player to be updated - which I did. Ever since then whenever I go to a webpage needing Flash Player I get the message "A problem with this webpage caused Internet Explorer to close and reopen the tab". This happens twice and then an IE9 error page.
I have read the discussions in here about the problems with Flash Player 10.3 and have tried the various solutions. I have updated to 10.3.181.16 having tried 15 and 14 previously. Same problem.
I have reset IE9. Same problem.
I have disabled all add-ons which stops the problem. If I enable just the Flash Player add-on then the problem recurs. Since there are so many webpages that use Flash I do not want to run my browser without this add-on running.
If I enable the add-on and run IE9 using software rendering instead of GPU rendering then I don't get the problem. However, this isn't exactly making the best use of the resources on my laptop.
This may well all be related to the 10.3 problems but no one seems to have mentioned having a problem with tabs closing and reopening so I thought I would post on here to check.
Any suggestions for how to solve this (other than using software rendering)?Thanks again for your reply. I appreciate the time you have taken to respond.
I think, however, you misunderstand the problem. IE9 does not reopen the tabs on just one website - it is doing this on every website that needs Flash Player. Therefore, running in Compatibility mode is not an option. In fact, because IE9 reopens the tabs so quickly and then ends up with an error page, I cannot even click the Compatibility button anyway.
I could use ActiveX filtering - true. All that this means is that Flash does not play on any of the websites. When I want to re-enable ActiveX for a particular website where I need to see the Flash Player item, this just triggers the error.
This problem also happened on .14, .15 and well as the current .16 version. It did not happen with the previous version of Flash Player that I had on the system (version 10.2 I think).
The fact is that either Flash Player or IE9 or both is/are broken. The two choices I am still left with are:
1. Use software rendering (which contradicts the latest advertisements for IE9 about unleashing the power of IE)
2. Use another browser - I have no problems with either Firefox or Chrome
