Wait evnt

hi
normally ,what should be top most wait-events to know good performance database

Your question does not compute.
Good performance is based on timing not wait events.
If the users are not complaining, if you are meeting your SLA, then you have good performance.
If users are complaining then use wait events, in connection with good detective skills, to identify the bottleneck.
This is science ... not magic.

  • Wait for event step..

    hi all,
    I have a wait for event step in my owrkflow and it is working fine. My problem us i am not able to trigger this event using program can anyone please let me know what i am doing wrong. following is the code i am using to trigger the event

    however if i execute the FM SAP_WAPI_CREATE_EVENT by passing the values it works fine.
    Thanks
    Saurabh

    Hi
    however if i execute the
    FM SAP_WAPI_CREATE_EVENT by passing
    the values it works fine.
    It will trigger only when you execute the above function module or
    SWE_EVENT_CREATE because 
    You have a BO and an event associated with it now when you want to trigger this this event through program then you have to make a kind of mapping between BO and your program so thta's what this Fm does, when ever you execute the program as you are passing all the values to the Function the Evnt associated with the BO is triggered.
    In order to trigger use SWE_EVENT_CREATE aand after calling this fucntion use COMMIT WORK statement
    Could you let  me know what condidtion did you write for the WAIT step to continue.
    Regards

  • Gc current request waits for concurrent DL inserts

    I see 8 different concurrent session runing following insert statement ( DL load ) on 2 different node of a 4 node RAC cluster (10.2.0.4). Table T1_TEMP is on ASSM tablespace. This DL insert from a ETL tool.
    INSERT /*+ SYS_DL_CURSOR */ INTO T1_TEMP
    ("C1","C2","C3","C4","C5","C6"
    ) VALUES
    (NULL,NULL,NULL,NULL,NULL,NULL)and they all observing 'gc current request' or "gc buffer busy" waits.. for several files with Block# 2. Wondeing why it's having so many waits on Block#2 ( I guess, t's file header block ).. Since it's a direct level Insert( Yes I have confirmed it's indeed DL insert), all it should aquire is TEMP segement above HWM and start inserting directly into DL. So just wondering why it's experincing gc related waits...
    I tried to find object name by querying dba_extents but it does not return any thing for file# 717, block# =2 or for any of the file#/block#2 mentioned below.

    Hi Tanel,
    From the OP's Inputs
    Buffer buy wait is with respect to : id#= 65549 (P3) in block#= 2
    gc current request with respect to : id#= 33554445 in block#= 2
    As you stated from first post,
    Block #2 is where the file level space usage bitmap header lives in locally managed tablespaces. This manages the file level space, not segment level.
    If you're doing heavy parallel insertions with small fixed LMT extent size then when segments are extending frequently you can end up with contention on that block. First of all you way for troubling shooting this problem is pretty good..!!
    My doubt, what is the reason that it would "end up with contention", since as user is performing "parallel insertions" small fixed LMT Extent size. In this case does row extending would not happen..??
    From the second post
    The ID# is a partially a bitfield and partially the class# of block involved in the wait.
    The lower two bytes indicate the block class. Which in your case is mostly 13 (if you look only at the lower 2 bytes of the values, e.g. 65549 - power(2,16) = 13.How about the "33554445" - (33554432 ->2^25) = 13
    I would be thankful to if you could added some inputs.

  • Problem with Threads and "plase wait..."-Window

    Hi everyone,
    I have a problem that I'm not able to solve in any way... I have a time-consuming task (a file decryption) which I execute in a separate thread; I've used the SwingWorker class, like suggested by sun-tutorial, and it works right. The problem is that I have to wait that the decryption have finished before continuing with program-execution. Therefore I would like to display a "please wait"-window while the task runs. I've tryed all the possible ways I know but the problem is always the same: the waitWindow is displayed empty, the bounds are painted but the contents no; it's only painted when the decrypt-task has finished. Please help me, I have no more resources....
    decrypt-file code:
    public class DecryptFile {
      private String cryptedFileNameAndPath;
      private ByteArrayInputStream resultStream = null;
      // need for progress
      private int lengthOfTask;
      private int current = -1;
      private String statMessage;
      public DecryptFile(String encZipFileNameAndPath) {
        cryptedFileNameAndPath = encZipFileNameAndPath;
        //Compute length of task...
        // 0 for indeterminate
        lengthOfTask = 0;
      public ByteArrayInputStream getDecryptedInputStream() {
        return this.resultStream;
       * Called from ProgressBarDemo to start the task.
      public void go() {
        current = -1;
        final SwingWorker worker = new SwingWorker() {
          public Object construct() {
            return new ActualTask();
        worker.start();
       * Called from ProgressBarDemo to find out how much work needs
       * to be done.
      public int getLengthOfTask() {
        return lengthOfTask;
       * Called from ProgressBarDemo to find out how much has been done.
      public int getCurrent() {
        return current;
      public void stop() {
        current = lengthOfTask;
       * Called from ProgressBarDemo to find out if the task has completed.
      public boolean done() {
        if (current >= lengthOfTask)
          return true;
        else
          return false;
      public String getMessage() {
        return statMessage;
       * The actual long running task.  This runs in a SwingWorker thread.
      class ActualTask {
        ActualTask () {
          current = -1;
          statMessage = "";
          resultStream = AIUtil.getInputStreamFromEncZip(cryptedFileNameAndPath); //here the decryption happens
          current = 0;
          statMessage = "";
      }The code that calls decryption and displays waitWindow
          final WaitSplash wS = new WaitSplash("Please wait...");
          final DecryptFile cryptedTemplate = new DecryptFile (this.templateFile);
          cryptedTemplate.go();
          while (! cryptedTemplate.done()) {
            try {
              wait();
            } catch (Exception e) { }
          this.templateInputStream = cryptedTemplate.getDecryptedInputStream();
          wS.close();Thanks, thanks, thanks in advance!

    Maybe you can try setting the priority of the long-running thread to be lower? so that the UI will be more responsive...

  • My iPad wont let me download apps it just keeps saying waiting.

    My iPad wont let me download apps it just keeps saying waiting.

    1. Make sure that you do not have a stalled download in iTunes - a song or podcast .... if you have a download in there that did not finish, complete that one first. Only one thing can download at a time on the iPad so that could be what is causing the problem.
    2. If that doesn't work - sign out of your account, restart the iPad and then sign in again.
    Settings>Store>Apple ID. Tap your ID and sign out. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    Go back to Settings>Store>Sign in and then try to update again. Tap one waiting icon only if necessary to start the download stream.
    3. You can also try deleting the waiting icons - tap and hold down on an icon until it wiggles - the tap the X on the icon to delete it. Then try to download again.
    4. You can try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your app preferences and device settings again.
    5. Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons

  • DVR Problem w/QIP7232P2 DVR Operation; HOW Long will I have to wait for 1.9.1?

    THE SHORT PROBLEM:
    1) DVR records only a few moments of pre-scheduled events then the recording stops with only 10 to 30 seconds stored content and this is reported in the on screen detail.
    2) DVR records a full 1 hour show however, after 20 or so minuets of playback, use of the fast forward, skip (to get around a commercial) or pause DVR functions will cause the playback to jump to the end and you can't see the rest of the story.  One must start the show over again, view stuff you have seen before to get to where the error happen.  If you fast forward too close to the point of the error, you will get dumped out of the show all over again.  Once you get close you just have to watch commercials and what you have seen before and then not use any DVR functions in order to watch the rest of the show.
    3) DVR records a full 1 hour show, you fast forward to a time that is say 50% into the show, the progress bar will move forward like normal to show you get close to the point of you stopped watching the show before (to help solve problem #2 above) BUT, if you go too far, the progress bar will jump back to the start of the show and you may be dumped out of the program or it may continue to move forward.  However the operation of the progress bar is not right.
    This would render the DVR less then useful.  Verizon has replaced my STB and talked me through the reset of AC power operation that is the normal fix for most STB issues.  I'm told this will require a software upgrade from 1.9 to 1.9.1.  OK, GET IT DONE and CREDIT USERS OF DVRs THE FEE PAID FOR SOMETHING THAT IS NOT WORKING.
    THE LONG STORY WITH DETAILS:
    All seemed to be well with the unit for a few months and the upgrade to the new 1.9 software looked like it went off without a hitch.
    But.....Starting on around 12/17/11 I noticed that my DVR was recording only about 10 to 30 seconds of programming during scheduled events.  Sometimes it would attempt to record the same event one or two times, each only lasting a few moments.  I called Verizon customer service I think on 12/20/11 and they asked me to pull the 120 volt power and then re-apply power.  This helped the problem but, remote testing seemed to show an issue and the customer rep decided a replacement unit was needed and Order No. MDDQ08V49U was created and another set-top box was shipped to me.
    It is too bad that the technology has been developed to allow the external storage of digital content however, one can't back the 200 plus hours of video one may have stored on a set-top box and restore it on a new unit.  It is also not possible to reproduce the vast extent of scheduling of events.  No, it seems when you change out a set top box, all the programming is gone and you have to spend an afternoon coping down the schedule from the Series Manager and then re-enter all new events by making new recording events; a very time consuming operation.
    So it is frustrating once after this afternoon is wasted reprogramming a new set-top is all done with the new set-top box installed, I find that on 1/5/12 when viewing recorded programming that should be one hour long, I only seem to get 22 minutes of playback.  I try to look at this in detail and see that the first 22 minutes indeed play back in a normal manor.  One is able to use the jump forward mode to skip over a commercial and all is good.  If after 22 minutes you don't do anything, playback will continue to the end of the 1 hour.  BUT, if after the first 22 minutes you try the skip or pause function, the program will jump to the end screen where you are given the option to: Program Options Page were you can select Play, Save until I delete, or Delete.
    On 1/4/12 I called Tech Support and asked what to do about this 2nd box having yet another DVR problem.  Once again I was asked to cycle the 120 volt AC power and disconnect and reconnect the coax "because electricity can build up in the set-top box".  (I thought that was a cute reason).  I asked the Customer Service rep if this was a Tier 2 or Tier 3 Troubleshooting method and she told me she was not authorized to tell me. 
    1/5/12 a Manager calls me back to follow up on a survey from the December service call and after seeing that I had a trouble ticket on 1/4 to see what is going on. He attempts to talk me into getting the on screen diagnostic screen to come up (press a mix of power and OK) but that just does not work like the old set-top box. We review the problem and he is not sure what else to do then send a Tech to the house to review the problems.  He did tell me the STB I had in December WAS a known bad number; something about an issue with ribbon cable fault going to the hard drive.  Well OK, but it seems ODD that the two like problems seem to happen to a known bad box and now to a new box that is not in the "bad" lot of numbers.  This new STB also had been running 1.9 like the old STB for some number of weeks/months without issue then BANG, a problem pops up!  It seems like this is a deeper problem but I trust with all the fact Verizon can find the right answer.
    1/6/12 Aaron Phelps, Cable Splicing Technician comes to look at the problem. Nice guy!  I show him the two recorded shows that have the problem.  He can't get the on-screen diagnostic up but we use the test via the Main Menu and all readings seem OK.  He also tests signals via an external meter with good results. 
    At last, he calls Tier 2 Tech support and I'm told by him that it seems some bug is in ver 1.9 and we will have to wait a month for a 1.9.1 to come out that should address a memory issue in the DVR.  I don't know is this is the real story but Aaron tells me the ONLY fix they have is to swap out STB and he has no other 7232 units so... I'd have to go back to a smaller hard-drive or wait a month to see what happens.
    To say again, it is a problem when the only answer in practice is to reboot the STB or replace it and this does not solve the problem.  The field Techs don't know about a software bug less they call tier 2 support.  Also, as it is so common to just replace the STB, the process may take only a moment in physical action to swap wires HOWEVER, it is an afternoon to get programming done so a new DVR is recording all the shows a Customer has established; on top of the time talking to phone Tech support and waiting for someone to show up to the home, that is a considerable investment in Consumer time.  If you can't back up the content with the local drive due to copyright issues how about a cloud approach? I'd encourage a known bug to be resolved quickly and perhaps solve the manor that a STB is backed-up and replaced.
    I learn on 1/6/12 my friend had like problems:
    xxxxxx address blocked
    Claire had the added problem that a pre set event she set to record change by an hour.  I've not seen this but, I see in the Forum URL below, another person had the same problem as reported by "DC-Videophile" on 01-01-12 at 08:33 PM.  On this same forum "rich3fan" reports problems that I have on 01-04-12 11:54 AM.  The very bad news would seem from "markjrenna" 01-04-12 09:29 PM where it is suggested that 1.9.1 will not be out before 1Q12!!!!  That is a long time to have this problem.

    I notice with this event, when you hit fast forward, the progress bar moves forward with time then at a point it goes back to the start point, even when good video is playing in fast forward.  This program worked beyond 22 min then failed at maybe 38 min.  When I tried again, it failed at another point earlier (maybe 15 min) so it does not have a pattern.

    and a lot more......... 

    I am having the same problems. My guess is that a lot of people are having the same problems and just living with it. Those of us who know where to go on the Internet come here to find a fix.
    It seems Verizon has some explaining to do. Maybe they should try Beta testing new software a little better. I would rather have to wait longer for something that works. I am sure that some manager or director said this is close enough, deploy it and we will see what happens. Well, you are seeing the problems. Time to fix your mistake.
    All of us are telling our friends about the problems. The longer this goes on, the more people we will tell about it.
    Wouldn't you rather us be telling our friends that their is an error in the new interface and that you are working hard to fix it?
    If you want to be up front about this, then just tell us. We are adults and can handle it. If you made a mistake, own up to it and give us some credit for doing your Beta testing in the field.
    Customer Service is all about telling the truth and if you made a mistake, admit it and lets move on with a fix. I do not want to be told again that I should be able to unplug it, power cycle it, try the on-board diagnostics, etc., etc.......
    I am going to be repsonding on a daily basis to keep this topic at the top of the list.
    Time to come clean. You will feel better Verizon.
    Let's talk tomorrow.

  • User must wait several minutes before NEW opportunity shows up in report

    When a user creates an opportunity, they will then add product revenue to it. After that, they need to run a report of the opportunity and send the quote to the customer.
    The report will prompt for the opportunity name and then retrieve the formatted quote form.
    The issue is, after the opportunity is created and product revenue added, when the user tries to run the report, the data selection will not display the opportunity. The opportunity will not show up until after the user logs out and then back into CRMOD.
    EDIT: The log out/in portion was just a coincidence and plays into a delay in some sort of background processing problem.
    If the user just waits , up 15 to 20 minutes in some cases, the opportunities will show up in the list. Sometimes, they appear very quickly, other times it take a very long time.
    I am surmising that this has to do with some sort of business function that runs in the background, and being a shared system, there is a backlog in the processing. Similar to the wait queue for data imports.
    Is this normal behavior?
    Edited by: nsidev on Aug 28, 2009 1:59 PM

    Hi, I think the problem is with the drop down prompt not getting refreshed with newly added opportunities, otherwise with the direct reports clicking the "rerfresh" link brings the newly created opportunity. The problem also doesnt seem to happen if the prompt is of type "Browse through choices and/or type in directly "

  • Mark waiting and cancelled tasks completed

    Hi All,
    is there sql somewhere that can mark certain tasks that are in waiting and canceled status to Completed?
    Thanx.

    I would suggest using the APIs to update the status or use the manuallyComplete API instead.

  • ITunes Match Unable To Get Past "Waiting for Apple to deliver your iTunes Match results..."

    Been trying for days but it just gets to "Waiting for Apple to deliver your iTunes Match results..." and then stops and allows me to press the Start button again to start the match process.  Sometimes I get error -3231.
    I've called Apple and they want $19 to solve the issue even though I paid the $25 for Match.
    I've turned iTunes Match off.  Turned Genius off.  Logged out of my iTunes account.  Quit iTunes.  Restarted. Logged back into iTunes account.  Turn Genius on.  Turn iTunes Match back on and let it go through the process again with no success.
    My library has a couple hundred songs less than the 25,000 max but it is pretty large.  Had the same issue when I tried with a smaller library some time ago.  I've created a new library and have the same issue.

    Hi,
    You should consider rebooting your internet router
    Then try holding option key whilst turning off match. Close iTunes and then reopen. Turn on iTunes Match and select add this computer.

  • I set up family sharing wrong, so i left family sharing and joined the right way agin but an error occurred and now it tells me I'll have to wait 364 days to rejoin again! How can I reset my account so I can use it again?

    WWhen I set up family sharing i did it with me as family organizer, but as my spouse is the organizer I had to leave the "family" I created and join his. But while setting it up an error occurred, and the screen went blank. Now I tried to join his family sharing again, and my phone keeps telling me I can't because accounts can only join families twice a year.
    I Don't really want to wait 364 days from now, is there a way in which I can reset my accoint so I can join family sharing again?
    Apple support doesn't have a solution for me yet!
    KInd regards

    This morning I looked at my family sharing account again an IT WORKS NOW! Think Apple has done a reset to my account, though I'm not exactly sure why! So I hope it works for you guys as well!

  • Error while loading a Cube in BW - "Waiting for Semaphore"

    Hello Experts:
    I seem to be having a frequent problem while doing a Delta load from BW (3.5) cube to exactly similar cube in BI 7.0.
    The load is done daily via a Process Chain. Before doing the Delta load, I also have a step to DELET Index from the
    cube in BI. The Delta loads have been successful but frequently they take about 7 or 8 hours to load. The number of
    records are not many 80,000 to 140,000 records range. There have been successful loads for similar range withing
    7 or 8 minutes. However, when it gets hung up it takes 7 or 8 hours.
    Looks like it is a Lock happening in 3.5 BW system. Tcode SM12 shows that it is locked and then in T. Code SM66, it
    shows that it is hun for resources..... The message inicated is "Waiting for Semaphore". After about 7 hours, the load
    automatically happens.
    This is causing issues becuase the upward data loads don't happen and Users can not access the data until late afternoon
    for their planning in BPC.
    Is there a way this error or Waiting for Semaphore be avoided or time is reduced....? How can I achieve this? Any
    fne tuning tricks anyone can suggest please......!!
    Thanks a lot in advance.

    Thanks to both of you....  ppreciate the feedback.  I guess, I will have to wait for the situation to arise again as today's delta went normally.  I will see if this happens again.  I am not sure whether the Semaphore number is same as the "Work Process Number" in SM66 (which was 3 in my case) or is it the Process ID (which is 22872082 in my case). 
    If I go to SM50, I shoudl find either the Process ID then.
    Would I be searching for the OSS notes corresponding to Process ID (in this case 22872082...? or would it for sempahore number (if it is different .... as I mentioned 3 in my case..?
    Could you please clarify which is Semaphore number and if it is same as the process ID I am talking about so that I can search for the right OSS notes.
    Also, finding all this will only tell me why it hung.... but is there a way we can make it kick off and not get stuck or I have to wait it out until the resources get released.....?  Which in my case then would stil be a wait for 6/7 hours!!
    Apreciate your feedback.
    Best.....  Lee

  • My iphone 3GS no longer syncs with iTunes. The phone is recognised, backs up but then I get an error message: "Waiting for changes to be applied". BUT unlike other people, it doesn't stay stuck on it, instead the process closes down immediately

    Hi all,
    Apologies: I've just joined the community and didn't quite figure how to write a msg! Hope it works...
    Anyway,
    I read many posts on this annoying error message (Waiting for changes to be applied) in the last 2/3 days, but they all refer to the sync staying stuck on it.
    Mine doesn't.
    I read the message, then it quickly shuts down the sync and the iTunes progress bar only shows the apple...
    As suggested by many, I removed voice msgs, turned off/on, tried to sync in individual stages (calendar only...) but nothing works.
    I am up to date on iTunes (11.1.1.11) and have IOS 6.1.3 on my phone, to sync on a Win8 pc (all worked fine until recently).
    I have had this phone for several years and it has never done this.
    It worked absolutely fine, until I loaded the latest version of iTunes it seems...
    Any suggestions?
    Many thanks

    ALSO, on the iPod under Settings>General>iTunes Sync, you may need to back out of the "iTunes Wi-fi Sync," and reopen it to get it to update.
    (I use iTunes 11.1.5.5)

  • Hp LaserJet P3015 printer "waiting for printer to become available" message

    Hello All,
    I have searched through many message boards about this issue (some steaming back to as far as 2009) and I have yet to find a solution that has worked for me.
    Background of situation:
    In my office we have a dozen iMacs and Networked hp LaserJet P3015 printers.  Most work perfectly fine with out issue.  We are currently running 10.8.4 OS.  There are a few issues that seem to be unique to users or types of iMacs.  1) Three brand new iMacs (the skinny ones that come without the CD drives) where showing a message prompting for the "printer operator group".  I have that setting turned off but reguardless I added the user accounts to the "printer operator group" as well as the "printer admin group".  After I did that the users started to recieve the message "waiting for printer to become avaible".  When this message appears it never printers (I left it for a 20 minute period to no avail).  I have tried a whole host of fixes with short term success but the issue keeps reoccuring.  Here is a list of fixes I have tried:
    What I have tried
    1) I plugged the iMac directly into the printer via USB cable to install the drivers locally
    2) I added the user to the printer operator group and the printer admin group
    3) I checked all settings on both the printer and computer
    4) I have removed and re-added the printer several ways (from the network and directly via UBS cable)
    5) I checked the Ethernet connection to the printer (all are fine) (also eliminated the need for it by directly plugging her in via USB cable)
    6) I have "power" shut down the printer
    7) I restarted the printer settings on the network to eliminate any lingering issues
    8) Made sure the software is up to date (which according to some message boards is what the problem is)
    9) I have replaced both the actual Computer and Printer (with another brand new iMac), while additionally creating a new user account to eliminate hardware and faulty user settings as the culprit, as well as plugged the printer directly into the computer and removed it from the network.
    10) I prayed to the IT gods
    Other Notes:
    I did see a solution from a message board that said to delete all "hp_" files in system/library/extensions and then directly plug the printer into the computer to install the drivers that way (which he said worked) but the guys also said that if he ran software update then the issue would re-occur.  This seems to be counter productive as I like to keep all software up to date
    What I have noticed:
    - The issue seems to affect the newer iMacs in my office more then the older machines despite everyone running the same OS version
    Thank you all so much in adavanced for your time reading my post.  The issue has been extremely frustrating for both me and the end users and I appreaciate any help that anyone can provide (even if its just pointing me in the direction of another message board)
    - Chris

    You have not mentioned it but based on some of the things that you have said, I would assume that the Mac's are bound to a domain. So, for one of these Mac's, if you logged on locally and then created a print queue to the network printer, do you get the same message?
