• Wait events

  Hello

  the 11.2.0.4 SE on Win 2008

  then, do not have AWR. Then having the Top 5 leading timed events

  I ran the following:

  SELECT EVENT, n.WAIT_CLASS,

  TIME_WAITED_MICRO, ROUND(TIME_WAITED_MICRO*100/S.DBTIME,1) PCT_DB_TIME

  V $ SYSTEM_EVENT E, V$ EVENT_NAME N,.

  (SELECT the DBTIME VALUE OF V$ SYS_TIME_MODEL WHERE STAT_NAME = "DB time") S

  WHERE E.EVENT_ID = N.EVENT_ID

  AND N.WAIT_CLASS NOT IN ('inactive', ' E/s system') and ROUND(TIME_WAITED_MICRO*100/S.DBTIME,1) <>0

  ORDER BY ROUND(TIME_WAITED_MICRO*100/S.DBTIME,1) ASC;

  

  Can I conclude that the most important issue on the database is db file sequential read and should be the subject of an investigation?

  Or rows returned are meaningless on the performance? Tunning?

  Do you sugest any other question?

  Thank you.

  Hello

  > Can conclude that the most important issue on the database is db file sequential read and should be the subject of an investigation?

  A wait event isn't a problem. It is just a little work of the database and the database is there work wo.

  This is a problem only if you too (in many calls of i/o) or slow (long of IO call duration)

  Your instance has been started just two minutes ago, no? This is not very important. Caches must warm up.

  You need to install Statspack. Read about it ORACLE_HOME/rdbms/admin/spdoc.txt

  Kind regards

• Apps stuck on waiting after updating iOS 10

  Hey guys,.

  Since upgrading to iOS 10 a couple of my applications like facebook are stuck on waiting and I can't access it. I tried all the usual fixes like restarting the phone and enter the purchased section on the app store, but it won't let me even remove apps or stop the download.

  Sometimes simply knock on the home screen application stops the download and then you are able to resume and it works. Otherwise... I'm afraid you will have to reinstall iOS.

• Free trial of InDesign stuck on "waiting".

  I am trying to download a free trial of Indesign, and he is stuck on "waiting". He said 'pending' for an hour now. I tried to uninstall everything, using the Adobe cleaner, rebooting, etc.. Nothing has worked. Please help - I need this program now.

  I guess that you download at the bottom of the link:

  Direct download links of Adobe CC 2015: 2015 creative cloud release | ProDesignTools

  This is a temporary solution, but it is very important to solve the problem with CA. CC it not only installs the app, it auto-detects also the necessary updates from time to time, whenever there is change of operating system like Windows or Mac OS, respective updates of patches are released.

  but you can also download these patches similarly direct link, but you will need to check the Web site frequently to check the available updates, or you can also check the Help menu of Apps.

  Believe me, you have no idea how useful this Forum is for people. Feel free to ask if you need further assistance, we will be happy to help you...

• Wait events, SQL * Net message from client

  Hi all

  I have a doubt about oracle wait events, specifically of "SQL * Net message from client. I've read a lot about this, I've seen some say that network and other material resources can provoke him, and saw that the problems in the application code can cause it too. I am tracking a few tests here and I don't have that chooses are the double event, usually a lot of SQL * Net message to client waiting (I used sqlplus, developer sql and pl/sql). Can someone explain to me why? Another question is where this wait type cause interference, meet it demand for the database and stays on hold and do not meet another request so that the wait is over, is it? The waiting just finish when the application closes the database connection or there is another way to end the waiting?

  Since then, thank you very much.

  Hello

  chooses double what usually causes a lot of SQL * Net message to client waiting

  Do you run them from your server applications or from the DB server itself?

  "SQL * Net client message" is an idle wait event although he'd still explain to the elapsed time of the query.

  It indicates only that the database is waiting for the other entries of the customer and when he expects the DB, those expectations get incremented.

  I suggest you explore size SDU, RECV_BUF_SIZE, and SEND_BUF_SIZE parameters.

  Hello

  What should worry, to this end, I have sguuest read you link below.

  http://www.Oracle.com/technetwork/database/bi-Datawarehousing/TWP-parallel-execution-fundamentals-133639.PDF

  As the default value for sufficient, depends on place on many factors as optimizer, which can not sometimes be enough when set to default values, cpu, memory, data, resources.

• My Adobe CC application on windows 8.1 tries to download updates for Indesign, Dreamweaver and Flash, but it is stuck on "waiting" indefinitely. How can I solve this problem and start downloads, updates?

  My Creative Cloud Deskop on Windows 8.1 application gets stuck on "waiting" when you try to update applications. Please help me understand how to get the download to start.

  I have a Gigabyte P27.
  8.1 Windows 64-bit

  and a full subscription of CC with Creative Cloud Desktop application as well (this is where I will have questions)

  All my installed applications work fine. I'm enrolled correctly and synchronization also works very well.

  -Very well, so after a lot of trouble trying to open Photoshop CC, go to help and updates it. This has opened a different kind of Application Manager, and when I invited to be updated, my UAC Windows asked the permission of the administrator and I said OK.

  The files are now all the manual update. I'll fix the permissions in the OOBE folder, then remove the "run as Administrator" box of the update. Maybe it will work. I'm going to come back here to confirm that where someone always ends up this question.

• Wait events "direct path write" and "direct path read".

  Hello
  
  We have a query that takes more than 2 minutes. It's a 9.2.0.7 database. We took the request trace/tkprof and identified there so manay 'direct entry path' and 'direct path read' wait for events in the trace file.
  
  WAITING #3: nam = "Write" direct path ela = 5 201 p1 = p2 = p3 70710 = 15
  WAITING #3: nam = "direct path read" ela = 170 201 p1 = p2 = 71719 p3 = 15
  
  In the light of the foregoing, "p1 = 201" is a the file_id, but we could not find any data file, the temporary file, the control file with this id # 201.
  Can you please let us know what "p1 = 201" here, how to identify the file that is causing the problem.
  
  Thank you
  Sravan

  Whatever it is:

  show parameter db_files
  

  back? I think, is that it returns 200.

  Read the file live and direct file writing events are reads and writes of tablespace TEMP. Wait events, folder # is reported as db_files + id of a temporary file. So, 201 means temp #1 file.

  Now, as to your real performance issue.

  Without seeing the SQL and the corresponding implementation plan, it is impossible to be sure. However, the most frequent causes of temporary entries are the operations of sorting and group by operations.

  If you decide to display your plan and SQL execution, please be sure to make it readable by formatting it. Information on how to do this can be found here.

  Hope that helps,

  -Mark
