Blocking cause

Hi Experts,
I'm on Oracle 11.2.0.2 on Linux. In my database, there is a reported deadlock and I'm not able to find the right or even two different sessions participated in it. Here is the info of the deadlock trace file. I will be grateful for information on the cause of the problem.

Next time I'm on a RAC system suitable I will check if there is something else that gets dumped, which may help. In the meantime you could simply model a PK block on your system to see what is happening:
Example 1: insert into tableX id = 1 (where id is the pk)
Example 2: Insert tableX id = 2
example 1: insert into tableX id = 2
example 2: insert in tableX id = 1

Wait and see what happens, then search for the trace files.

I finally managed to find some time to work up to a two-node RAC and tried the above test. As expected that I saw not a trace of ORA-00060 dump in a FOREGROUND process, what I got was a dump of the process backwards plan lmd. "Of course, was particularly interesting, the" Global Wait-for-Graph ' (WFG).

{code}

Wait-For-Graph (WFG) overall to DDT [0.1]:
0x9dc4f498 wq 3 2 cvtops x 1 TX 0x140009.0x1fc (ext 0 x 5, 0 x 0) BLOCKED [2 000-0001-0000000 C] inst 1

{code}

Notice the similarity, it's in the structure of the WFG in your example
And here are the details of granted queue / convert the same trace:

{code}
GRANTED_Q:
LP 0x9e1c9150 gl KJUSEREX rp 0x9e7ac4a0, [0x2000d], [0x31e9], [TX] [ext 0 x 2, 0 x 0]

CONVERT_Q:

Master 1 owner 2 1 3 mseq rseq bast 0 x 1 0x77d497ad history
Convert opt KJUSERGETVALUE

{code}

Again, note how similar, they are to your example.

As a little extra - these excerpts come from the body which received the deadlock message - and the session information in the identified lmd trace file the local session in detail, citing the SQL it was running (like you). At the same time the process on the other instance lmd also dumped a trace file describing (among other things), waiting in this instance and the SQL session he had run when he started waiting.

  • Username blocking which is held on the database at the time

    Hello

    Using oracle 11.2.0.3 and concluding that on sat morning (03:30 a table cannot be updated due to an exclusive lock.

    merge into the affected table.

    Nothing else, we are aware to access the table at the moment because of some process must be because of the ORA-00054 - busy resource.

    Is there a way that we can identify what caused the blocking / causing the lock - happenening each week.

    Thank you

    You get it in history, when you get the lock again and then query the table mentioned above.  In addition, to check any kind of blocking session problem use this query.

    Select b.session_id, a.SERIAL #, «blocker details» a.username

    session $ v has, dba_lock b

    where b.session_id = a.sid

    and b.blocking_others = 'block ';

    Concerning

    Asif Kabir

    I find what the problem is. If you enable sync extension in setting-> sync (which I activated recently in my PC and laptop, I believe that this is a new feature), then it would break. That's why my lab PC and laptop are broken everyday. I'm in China, so there may be some sort of internet block causing this bug. But the synchronization of other are fine.

  • How to record entries of UI with the data measured in a TDM file?

    Hello

    I built a user interface to monitor and control a pump test bench, I use the USB-6212 in a Windows PC with the new SW and readers.

    Now I try to collect all the measured data and control values in the UI, permanently at 1 kHz and write it in a single file of CT.

    The problem is that only the measured signals get connected, but only a few values at the beginning of the file are saved in the user interface; then all empty.

    I have all tried, producing waveforms, synchronize them with measured data for the same stamps, aling & resample and blocks of collector of the Toolbox Signal Express, but there are still some missing data in the user interface.

    In my original configuration, indicated in the post, I set up the block of analog to read continuously at 1 kHz with 100 samples, while output and analog digital on-demand writing. I have included the file complete, just in case some block causes disruption.

    Your express DAQ screws will probably be reading/writing of multiple samples for each run, then wire you a single value for your set points. The use of the data type of dynamic signals hides this information from you (that's why nobody is using them once they become more familiar with LabVIEW).

    You need to take only the last value of dynamic data, or touch your set points so they are the same size as your dynamic data. If you write 100 samples at a time, then you will have your set points only once by 100 values. You must create a table/waveform of 100 points with the same value.

  • What are the alternatives to the update of the indicators using nodes of property?

    Hello

    I'm building a VI that must update several controls/indicators in several points throughout its execution. It must also be able to accept the new values of the controls at any time.

    The problem is that all these controls and indicators on the face before of the VI another who called my VI. The current version of my program updates all these controls and indicators using references and property nodes (each indicator/control to be used has its own reference on my VI control, and these references are then sent to nodes of property), which makes it naturally slow.

    At the moment I plan to rebuild my VI so that the principal is able to recover data without the help of the references, but it is not only a lot of time but also difficult and impossible without my code turning into a massive pile of disorganized (especially since the lab computer is quite slow and the main big enough VI that by pressing the button "clean/re-organize block" causes a crash).

    Alternatives to this? Queues?

    This (my nugget events) is the best general solution, I came here.

  • Windows 7 automatically my volume control (results in all devices being cut).

    Hello

    I've traveled around a solution to this, but I had no chance at all.

    I use Windows 7 Ultimate x 64 and I find that the volume control seems to have a mind of your own.  After starting my computer, sometimes the sound is muted.  If I try to increase the volume using the volume control slider, Windows 7 he dragged down once again and I am unable to do anything unless I reboot and get lucky he did not yet.

    There are also times where it will be repeated enough randomly while I have a game open or I play music or just about anything else.  Once it does, it is impossible for me to put my levels sound back as they were, without having to reboot.

    Specifications of the PC:

    Intel Q6600 @ 2.4 ghz.
    Motherboard P5KC with 4 GB of RAM.
    Creative X - Fi fidelity.

    I tried right click on the volume control, go to the sounds-> Communications tab and selecting 'doing nothing '.  I tried to update to the latest drivers available for my sound card, directly from the creative support site.

    I don't know what else to do.  It is extremely frustrating to have to reboot unnecessarily several times a day because of this problem.  I googled for answers and saw that there are other people who have similar problems, but they seem to use a different material than I am, and there is not a lot of information circulate another that "update your drivers", which did nothing for me.

    Could someone please recommend anything else I can try?

    You guys are going to be shocked but - after I had all the settings and the tinkers pilot and got no where - I UNPLUGGED my wireless mouse and used the pad - I had to order my volume - up and down immediately.  Something with the mouse is in conflict with the sound program.  Maybe my wheel mouse or key has been blocked causing an automatic decline or increase - not sure.  For me, the mouse was the culprit - good luck!
