  Can I uninstall predictive function? If this is not the case, can I do the delay so long as it has the same effect?

  Hello, Keith,

  You have posted to the Feedback Forum.  Your question is beyond the scope of Microsoft Answers and must be validated in the TechNet Forums.

  There are a wide variety of functions of prediction you can use, but you must choose the function that fits the type of model that you created. Usually, this choice depends on the algorithm used to create the model.

• Problem with BasicEditField and predictive text

  What can I do for remove predictive text in a BasicEditField programmatically, as the search for address book entry?

  I think that I can't do with the code, allowing only multitap in the context menu, but the user has seen the AddressBook and want the same thing.

• Query is running slowly (30 sec) first, then quickly - how to find out why?

  Hi all

  First of all, a warning: we are a company of rapidly growing software which provides a SaaS-like solution and is hosting an Oracle database for our own software running at client locations. I'm still not a DBA, but I've been learning for a while now and will follow appropriate courses, next year. This problem becomes urgent enough, however.

  We have an Oracle 12 c (12.1.0.1.7) running on a pretty Beefy hardware (card SSD 8 cores, 72GO,) and it works fine. One of our applications raise queries that run slowly very often, but when I run the same query through Toad, it is very fast again. Sometimes I can make the same query to be slow again by changing settings, adding values to an in(), etc., but not always. By not being is not in a position to know WHY the query is slow, I can not as a solution. We have been struggling with this problem for some time (more than a year, I think) and had the same problem when you still run Oracle 11.

  Some more bits of information that might be relevant:

  -This user defines cursor_sharing for force, per my request (the software itself does not lie)

  -J' put optimizer_index_caching at 25, because I know the DB all be in memory.

  -J' put optimizer_index_cost_adj at 50, because I saw full table scan too for my taste. The two parameters when it is while the queries were not already productive.

  -Memory: memory_target = 40 GB, db_cache_size = 5.5 GB, pga_aggregate_target = 8 GB sga_target = 30 GB

  -Optimizer_dynamic_sampling is the default, 2.

  -J' saw a few query plans have a note, something like "Explain plan was made with the statistics from previous executions. All do not have this, however.

  -J' saw some explain plans in which the actual recordings differ a large amount of the expected records, planned somethings was 1, real was 4 billion...

  -We actually had to add / * ordered * / for some queries to speed up execution. It's been a few other issues have better results (20 sec every time! to 200 ms), but worse when Oracle has finally found the execution plan (40ms).

  -Many queries seemed to start with arrays of harm to our taste.

  -A copy of the database, running locally, also had some problems with queries - the plan of the explain command took 2 seconds, the query itself only a few Ms. the same database of course does not receive any insert/update statements.

  It may be important to note that this scheme receives a lot of updates and inserts, so I thought that it could screw up the statistics?

  As I wrote, we have been struggling with this problem for a long, long time. We have made changes to hardware, the parameters of the Oracle, the client software, everywhere, but are no closer to a permanent solution. Any help would be greatly appreciated!

  Kind regards

  Jelmer

  In particular the line 25 confuses me. Always this BITMAP AND even that crazy E-lines / difference A-lines. I'm sure that's the only reason for the poor performance of this query...

  I think you have a mixture of different effects here, which doesn't makes it really simple to understand exactly what is happening. To some extent this seems to be caused by the new features added in 11g and 12 c.

  1. looking at the trace of the files provided above, there seems to be some problem with dynamic sampling overload (DS). This seems to be one of the reasons why you have this "first slow exec", the second fast exec, in this case without a change of regime. In this trace file, it takes 5 seconds or more to run all these queries recursive dynamic sampling as part of the generation of the plan, and there are two DS queries that contribute significantly to that time (more than 3 seconds for these two DS queries).

  In order to have OPTIMIZER_DYNAMIC_SAMPLING 11 value causes these additional queries. The advantage of this setting is that you get good enough (join) estimates. Of course, it is difficult to judge how much you make this setting and how you lose the overhead of generating plan. New DS queries make use of the RESULT_CACHE have, in principle, reassessment of the same DS queries should come from the RESULT_CACHE. However, if your RESULT_CACHE is too small to contain all of the query results (although these result sets is usually very small) you can sometimes get slowdowns in generational terms if these queries need to be run instead of pull results from the cache.

  2. the function of vibration of statistics of course is involved and sometimes leads to a re-optimizing. Once again, this could then lead to the problem mentioned in point 1., if DS requests takes a long time to generate the plan.

  So these two functions together could lead to some difficult to predict behavior (slow first => possibly caused by DS, second time slow => caused by Feedback: statistics, leading again to DS, third etc. quick time.). It may also explain why you see 'first exec' slow, second fast exec, if re-optimizing na not take too much time and lead to a better execution plan.

  3. the special regard that seems to be the wide track as part of an internal source of lines join nested loop - and in this case, the estimates are * iterative *, so be careful when comparing E-lines (iteratively) with A-lines (cumulative across all iterations). The index used functionality combine to combine two indexes TASK_IDX1 and TASK_IDX2 suggest that it would be beneficial to add PERSON_ID to TASK_IDX1 and maybe get rid of TASK_IDX2 - but it might be appropriate to other queries, which I can't really judge. You can then check if adding more attributes to TASK_IDX1 it would make even more selective about the level of the index, as most of the lines for this particular query is filtered on the WORK table, so adding TASK level. FIXED, TASK. CLOSED and/or TASK. PLAN_START / PLAN_END it would make an even more effective operation. But adding PERSON_ID should solve this particular problem.

  4. the 'quick' this query (mentioned somewhere at the beginning) variation has no merge view inline (SELECT HELP... GROUP BY...), then you can try this by adding a NO_MERGE hint to the inline query (SELECT / * + NO_MERGE * / AID...), just to see if that gives you several times the plan 'rapid '. I still think that the index change described might be the best choice.

  5 SQL Directives of the Plan have been mentioned a couple of times, and I think that it is not quite clear to you what they are. They are not "advice", but are a new feature added to 12 c where Oracle persists some information on bad estimates and then evaluates these SQL Plan plan generation for dynamic additional sample queries and the production of statistics to create additional guidance extended statistics. I don't have enough experience with this new feature and therefore cannot judge how they play a role here. You can ask DBA_SQL_PLAN_DIR_OBJECTS and DBA_SQL_PLAN_DIRECTIVES to see if there are tickets for your particular objects in question.

  Onkar,

  I don't appreciate posting you this issue in several forums at the same time.
  If I know you also posted this on Asktom, I wouldn't even bother.
  As for your "problem":
  First of all: some kind cursor_sharing MUST have been implemented. Oracle is a predictable system, not a fruitmachine.
  Anyway, your statement that '0' is replaced by a variable binding is simply false. If you really believe this isn't fake, SUBMIT an SR.

  But your real problem isn't Oracle: it is your 'application', which is a mess anyway. Allowing for alphanumeric numbers is a very bad idea.
  Now, you already put workaround on workaround on workaround on workaround.
  Question is this: it is terminal, and you must either to kill him or to replace it.

• On the prediction of Word (end of Word).

  Hello
  
  I wonder if the end of the Word can be done in the form of Oracle.
  
  Say that there is a text tabled, when the user makes several enter queries, when it
  types of something, word prediction/word completion will invite the history of query words.
  
  Is this possible in the form of ORACLE 11 g?
  
  Kind regards

• Performance problem - Index is not used when a string of zero padded is queried

  Hi all
  
  I have a table T1 that has many columns. One such column C1 is a varchar2 (20). T1 has 10 million rows and there is an index I1 called C1. His stats are updated for tables and indexes. Here are the scenarios:
  

  Scenario 1
  select *   from T1 where C1 = '0013206263' --Uses index I1 
  187 ms
  Scenario 2
  select *   from T1 where C1 = '8177341863' --Uses index I1
  203 ms
  *Scenario 3*
  *select *   from T1 where C1 = '0000000945' --Uses Fulll Table Scan --Very Slow*
  *45 seconds*
  
  When I force the sql to use the index through a hint, it is working fine:
  Scenario 4
  select /*+ INDEX (t1 i1) */  *   from T1 where C1 = '0013206263' --Uses index I1 
  123 ms
  Scenario 5
  select /*+ INDEX (t1 i1) */  *   from T1 where C1 = '8177341863' --Uses index I1
  201 ms
  *Scenario 6*
  *select /*+ INDEX (t1 i1) */  *   from T1 where C1 = '0000000945' --Uses index I1*
  *172ms*

  Is there a reason for this problem of performance? Why the optimizer goes for FTS in scenario 3?

  It's balanced height histogram - by default in 10g if you do not deliberately block histograms you get histograms.

  => working on this now because there is a power outage now

  No need, your response to Justin provided examples which proved the point.
  If you expect always a few lines for all values of this column then you must ensure that this histogram does not builds. To avoid histograms in general, you must specify method_opt like 'for all columns size 1' in the call to dbms_stats.gather_table_stats; and don't forget that in 10g, you get an automatic job working at 22:00 that could remember his stats because he thinks that current statistics have gone stale.

• PIO, LIO and the cost of an Oracle query

  Hi guys,.
  
  Here are the definitions I've read to
  
  [http://www.orafaq.com/wiki | http://www.orafaq.com/wiki]
  
  PIO or physical i/o refers to the reading and writing from/to the disk.
  LIO or e/s logic refers to the reading and writing to/from memory (for example, / from the SGA buffer Cache)
  
  Basically, what I've read, the COST is measured in PIOs.
  
  If we had a query that returns to 20 lines, and:
  
  2 rows of 20 found in datablock X in the buffer cache
  4 lines of 20 found in datablock Y in the buffer cache
  
  2 rows of 20 found in datablock has the disk
  2 rows of 20 have been found in datablock B on disk
  2 rows of 20 found in datablock C disk
  2 rows of 20 have been found in datablock D disk
  6 rows of 20 found in datablock E disk
  
  then it would be correct to say that LIO is 2 and PIO is 5?
  
  And it looks like the cost of this operation was 5. Is this correct?
  
  Thank you

  The cost formula that you are citing the book is used to calculate the cost of access to a single table to a path indexed using a b-tree index.

  From the perspective of the optimizer, the cost of a more complex query consists of three components:
  A component of the CPU
  A component based on the number of unique block reads predicted
  A component based on the number of multiple blocks bed predicted.

  In the case of 'single table by index b-tree'-, we can assume that the CPU component is tiny (and it will be nil in any case in 8i or 9i if you have not enabled the CPU cost); and there will be no close readings. So for this path, the only component is the one-piece readings, and it's the formula gives number of Wolfgang Breitling.

  Technically, the cost of a query SO time for the query to execute measured in units strange slighltly. In 10g implementation plan makes this explicit by including a TIME column in the table of the plan; and you can see that this time column is always COST * sreadtim / 1000, where sreadtim is the time for a single block of reading as recorded, or a derivative, sys.aux_stats$.

• How to disable 10 IOS predictive emoji

  After the update to IOS 10 text predictive suggestions seem not to be as relevant as in 9 IOS, and a suggestion slot is taken up with an emoji. How to I disable this inept - I'm not a child of five and I text adults who can read without needing photos to help! It's really annoying and I want to turn it off.

  Thanks for all the suggestions - and no, I don't want to turn off the predictive text, only to stop the emoji characters to appear in a "predictive text" bar - they are not text they are pictures. Grrrr!

  Settings > general > keyboard > keyboards > edit > delete the Emoji.

• Predictive Emoji does not work

  I have a s 6 +.

  I have installed IOS 10.0.1 with the first backup of my 9.3.5 existing phone.  Then, I used the function "update and restore ' in iTunes to clear my phone and have a clean installation of 10.0.1.  Then I restored my 9.3.5 backup on my phone that works now 10.0.1.

  Everything works beautifully.  Except, the predictive function "emoji."   I should be able to type in something like "lets get beers for the party" and it should show the beers and the part emoji in above the keyboard auto-correction suggestions as I type each of these words.  Mine is not that.  TI just poster automatically corrects the normal which is always done if my message happen me to typo.

  I have only the Emoji keyboard English and active.  I have reset the keyboard dictionary. I tried enabling/disabling/off predictive function within the parameters of keyboard.   I have removed/added Emoji keyboard back in.  I force-restarted my phone in each handset the above.  I tried all the "fixes" that have been published, but nothing has worked.

  I get the Emoji keyboard manually and it analyze my text I typed and propose to change the words corresponding emoji - that works.

  But I'm looking for a fix to the predictive emoji bug.

  Try sending yourself a bunch of emoticons by text by opening your emoji keyboard and only randomly by tapping on them. Send you a couple of them. Worked for me.

• Predictive emoji does not

  I've recently updated to ios10 on my iphone6. After doing so, I was check for changes and searched the Internet for changes. I saw was predictive emoticons. Unfortunately, I can't get to work. I did all of the suggestions I found; Toggle the predictive keyboard, reset the keyboard, deletion/addition of keyboards, but none who has solved my problem.

  I can get emoji to highlight the words if I type the emoji icon, but the words do appear the emoji in the predictive text bar.

  Has anyone found an answer to this? I know that it isn't just me that I did a search and found others with the problem. Most of them have failed to get the legal solutions to work with them.

  I have exactly the same problem - im on a 6s and updated yesterday.

  My wife who also has 6 s set day and its predictive emojis are working perfectly.

  I tried to reset the phone, removing the emoji reset as suggested online dictionaries but did not make a difference.

  Seems like a lot of people have the question, a response from Apple would be appreciated

• How to remove predictive text bar?

  Hi all

  I've just updated to iOS10 and when texting etc. the predictive text bar is above the keyboard. On versions previous IOS you could easily hide this sliding downwards, however this ability has been removed. Am I stuck with that boring bar forever or is there a more in depth to remove this way?

  Thanking you in advance.

  Press on and press and hold on the emoji icon in the lower left corner and drag your finger up to predictive > Off.

• Emoji predictive isn´t work

  Hello!

  Today I updated my iPhone IOS 10 5 and I noticed that when writing simple words like 'Apple' or 'Hi!' they don t get "emojified". I have a mini iPad 2 with iOS 10 too and predictive emojis arises.

  I did a little research and found this...

  https://www.igeeksblog.com/predictive-Emoji-not-working-in-iOS-10-on-iPhone-iPad /.

  ... but nothing seems to work.

  Someone knows how to fix this?

  Thank you!!!

  I'm having the same problem. I even tried to reset all settings. No luck.

• iOS 10 - Emoji in not included in the predictive text

  Updated to iOS 10 today. Always play with it and try to understand things. But one thing that some friends of mine who can make my iPhone's display an emoji in the section of text predictive once you enter a word that has an associated emoji.

  I tried to disable/enable the predictive text, reset the dictionary of text and adding and removing of keyboards and languages, as proposed in line. Also tried to change these settings and hard/soft reset the phone. No dice.

  Now I am cause of GROUND I wiped my own dictionary that I was put in place for some time. Back to the AutoCorrect 'duck' If you know what I mean

  A few colleges to work can get emoji in predictive text while myself and others may not.

  This function does not seem to work anywhere in the phone, iMessage, Notes, E-mail, etc.

  Anyone else having this problem read this?

  I use an iPhone 6 Plus.

  Thank you

  Yes - I see the same question. The only thing I have not tried is a full restore, but I was hoping to avoid this.
