  Although you have an OUTER JOIN on TASK_DTL. TASK_ID, it is converted to a JOIN IN-HOUSE with (TASK_DTL. PKT_CTRL_NBR IS NULL OR TASK_DTL. INVN_NEED_TYPE = 1), which is the equivalent of the 'EXISTS' version above.

• Invalid object for this request

  Hi friends I have an another problem concerning textframe.

  my java script code is like this,

  firstLine var = xmlElement.lines.firstItem ();

  var newTextFrame = firstLine.textFrames.add ();

  -> newTextFrame.geometricBounds = [0,0,50,50]; error: Invalid object for this request

  If (firstLine.textFrames.length > 0) {}

  newTextFrame.move (null, [0, (newTextFrame.geometricBounds [2] - newTextFrame.geometricBounds [0] + 3) * (firstLine.textFrames.length)]);

  }

  After the execution of this file, I got a error: Invalid object for this request

  
  If anyone knows the soln please help me.

  concerning

  Tahir.
  

  The frame that you add is "inline" and is oversetting image, no doubt, so its geometricBounds are inaccessible. One solution is to create as anchored to instead and then make your changes and then put it back on line if you want to:

  var newTextFrame = firstLine.textFrames.add({anchoredObjectSettings:{anchoredPosition:AnchorPosition.ANCHORED}, geometricBounds:[0, 0, 50, 50]});

• Library meets live TV with the error: "there are currently no TV signal detected for this channel. The channel may be temporarily off the air. »

  I recently changed my TV card to an analogue of Hauppauge PVR150 at a Hauppauge DVB - S Nova S more. Media Center has worked well before.

  Media Library will recognize the new card, search and branch on 239 satellite channels, but may not display the channels giving the error message "there is currently no TV signal detected for this channel. The channel may be temporarily off the air. »

  I have installed WinTV 7 and that you can view all the channels very well in this program so obviously the map and the intensity of the signal are not the problem.

  In my quest through other forums, I heard problems re codec: mpeg2 and we tried several packs of codecs (including shark007) but with no improvement.

  My last move was to uninstall Media Center, uninstall all codec packs, uninstall the TV card and drivers, then reinstall the media library and the TV card and am still unable to view TV channels.

  Suggestions have greatly accepted.

  I've searched the Internet high and low for a solution to this problem and can lead to nothing more than what is proposed here by Divya.

  The problem seems to be fairly common and seems to be associated with codec. Most of the solutions I've come across related to the installation of media center alternatives and after several tries I finally opted for new version of Media Portal 1.1.0 beta

  Installed without a hitch and so far the interface is similar to the media library but has better customization and the ability to incorporate plug-ins.

  I did try the latest version (1.0.2) of the media portal, but said she had a few problems of stability (probably related to the W7 compatibility).

  Very happy now with Media Portal 1.1.0 Beta so will not need any other solution to this problem.

• You try to create VHDX or another format not supported for this version of the server

  Hello

  I have a problem with vWorkSpace do not load VM and I really hope that someone here might be able to add comments. We run vWorkSpace v8.5 on a box of windows server 2012 and v6.1 Hyper-V on Windows Server 2008.

  After running then changing the main image, I've updated the image of our cloud. Once the update of the virtual machine would not load, giving the below error

  We believe that it is somehow to do with Hyper-V under Windows 2008 and vWorkSpace running on Windows 2012 - the VHDX format is not supported by the version of Hyper-V server. A glance online confirms this. So my question is, how update the master image changed the format VHD vWorkSpace wants to use and is there a way to assign vWorkSpace don't know this format?

  I have widely in search of a solution to this line and not found anything it either, nor there seems a clear way in the vWorkSpace console to change that.

  Thank you

  Hello

  I suspect that you have created a snapshot on your model.  It is not supported, if you delete the snapshot so that the .avhd is merged to the vhd/vhdx and update the model in vWorkspace again.  If this does not work, you will need to delete the model of vWorkspace and then re-import.

  As you can see it table2 is exactly 1 row and join table1 on a correspondence of single line.

  Why the plan of the explain command seems (at least for me) to indicate that it looked like all the rows in TABLE1?

  the optimizer's decisions are based on the object (and maybe system) statistics: so it's a good idea to provide as much information as possible in these statistics. Basically, there is nothing wrong with statistics automatic collection job - so I would count on that if I don't have very good reason to use anything else. Of course, there are some situations in which it's a good idea to add a few adjustions for automatic collection: sometimes, there is too much created histograms, sometimes there is too little (basically you have histograms when the distribution of the data is not yet). And if there are columns with correlated values who serve together in boundary conditions then create extensive statistics may be a good idea. To make these adjustions, you can use the routines of pref dbms_stats. And sometimes, it may even be a good idea is not to collect statistics for an object and use the sample dynamic (dynamic statistics) for more detailed information on the cardinality of distribution and join.

  In the book of my opinion Jonathan Lewis cost base Oracle Fundamentals still contains the best explanation of the use of optimizer statistics - and Christian Antognini Oracle performance troubleshooting also provides a lot of valuable information about statistics and their gathering. Of course the documentation also explains the basics in detail: Managing optimizer statistics - 11 g Release 2 (11.2). And if you want to get a shorter summary, then you can always take a look at the Web of Tim Hall site: https://oracle-base.com/articles/misc/cost-based-optimizer-and-database-statistics.

• Generation to EXPLAIN the PLAN on a database that is open in READ ONLY mode

  Hello
  
  I use the Oracle 10.2.0.3 version.
  
  If my database is opened in READ ONLY mode, means that no insert/update/delete operations are allowed here.
  
  During the generation of the PLAN to EXPLAIN this, the PLAN_TABLE registrations for any SQL. But my database is opened in READ ONLY mode, means that no inserts can happen.
  
  So, how can I generate EXPLAIN PLAN for my SQL in this State?
  
  Thanks in advance.

  You can always do: 'explain the plan in some_table@remote_database' to avoid inclusion in the local database. Unfortunately 10g added an extraction of the sequence of the code "explain plan", and that's where the call fails if you have tried this distant approach on your version.

  Here's an idea that I have not tested. If you configure a link of data to your database from production to the database read-only, you could then do a "explain plan" in the database of production for the SQL statement by changing each object reference in the SQL statement to "object@readonlydatabase". In most cases this will allow the optimizer to recognize the statement as "entirely to distance" and get the optimizer on the readonly database to create the execution plan - which will be then written into the production database.

• Explain the plans differ as the parameter value changes

  Hi all
  
  My colleague posted a similar question a few days before. Happened because of some bad index. But now we are in a strange situation.

  It shows a hash join and nested with cost 16963 loops and gives the result in 2-3 seconds. It gives the same plan to explain even now if we use batch_id = '130609'
  
  Now all of a sudden from yesterday it gives different explain the plan below. Only difference in the query below is the value of batch_id

  All tables are analyzed today.
  
  Please share your thoughts on this.

  You have a histogram of frequencies on the BATCH_ID column missing at least 2 values according to your index statistics (235 buckets vs 237 separate keys).

  If the value that you use in the query is missing then this could be the explanation for the estimation of cardinality bad (since you're on pre - 10.2.0.4. In 10.2.0.4 that this behavior changes).

  The size of the sample of 5 300 lines is also very low, given the 57,000,000 lines according to the index statistics.

  You have two options (which can be combined):

  -Increase the size of the sample using a parameter explicitly estimate_percent, for example at least 10 percent

  exec DBMS_STATS. GATHER_TABLE_STATS (null, 'GACC_DTL_V1', estimate_percent-online 10, method_opt => 'FOR COLUMNS SIZE 254 BATCH_ID,' waterfall-online fake)

  -Get rid of the histogram

  exec DBMS_STATS. GATHER_TABLE_STATS (null, 'GACC_DTL_V1', method_opt-online 'FOR BATCH_ID COLUMNS SIZE 1', cascade-online fake)

  Note: Is there a particular reason why you store numbers in varchar columns? This might be the reason why Oracle believes that it must generate a histogram using the AUTO SIZE option.

  I tend to promote to remove from the histogram, but you must first verify the data if the BATCH_ID values are spread out and the histogram is reasonable:

  select
          batch_id
        , count(*)
  from
          gacc_dtl_v1
  group by
          batch_id;
  

  No constarints are at the DB level. All are processed Application level.

  Have you checked this in DBA/ALL/USER_CONSTRAINTS?

  It's also a good idea to have constraints at the level of the DB. It keeps your data consistent and quite often helps the optimizer. It allows even 10.2 and later to make things like the elimination of a join table that can make a huge difference in performance.

• a sql id have more than explain the plan so I'd like to come up with plan used at runtime.

  Hi all

  
  

  In a sql oracle11g having id several explain the plan so I'd like to come up with plan used at runtime.

  For example SQlID:-8yczg5zav14vt have 5 sql plan and I want to check that we execute at any time, please let me how I can check by sql queries

  Yes that's right cost is different, he means here another effective plan for oracle will analyze the declaration again and stored as new slider of the child. Especially since I explained that.

• explain the plan and so on

  Hello world
  
  
  could someone please provide me with details of explained the plan and I would appreciate some related details explain plan, trace and tkprof
  
  Thank you
  Shareef

  Hello

  PLAN of EXPLAINING is an Oracle utility that analyzes a statement and shows the expected execution plan. It may be different from the implementation plan real for a number of reasons.

  Extended SQL trace (10046 event) is a way to gather advanced diagnostic information. There are different levels, at levels 8 and 12 provide the greatest level of detail (you will be able to see the events of waiting and the bind variable values).

  TKProf is a utility that processes the raw trace files and makes shaped the output in a more readable way. However, some experts prefer to work with trace files "gross" - they are not so difficult to read, especially if you get some practice.

  There are other events of tracing: 10053 allows you to see what is happening inside the Oracle optimizer, 10104 allows to see the stats of hash etc join.

  Best regards
