The Oracle text and locking

Hi Experts,

I'm on Oracle 11.2.0.3 on Linux. I've implemented the Oracle text in my database. My production dba told me today that there is some locking problems in production and he sent me a report from ASH. I can post that ASH in a separate email thread, but first of all in this post you ask who are there known issues with Oracle expected text that it causes associated locks or lock? I read somewhere that oracle indexes text get defragmented over time. My full text index is defined as sync on commit. For example, should they be rebuilt over time - say drop and recreate them? What should be the frequency of doing this?

I'll be very grateful for any pointer on it.

Kind regards

There are different ways to optimize, some fast and partial and some more slow and painstaking.  Please see the procedure optimize_index of the ctx_ddl package:

CTX_DDL package

The type of optimization and frequency can be set in the index settings, as you do with sync (on commit), or on demand using dbms_job and dbms_scheduler.

  • Please help with the oracle text and select for each word in the sentence

    Hello

    I have a problem with a query which NEEDS to be done in SQL (not pl/sql in the stored procedure):

    Suppose that a phrase such as "Church of snowboarding."

    Can I divide this by using:
    Select regexp_substr ('church snowboard', ' [^] +', 1, level) word
    of the double
    connect regexp_substr ('church snowboard', ' [^] +', 1, level) is not NULL)

    now I have words 'showboard' and 'Church '.

    So far so good.

    Now I need for each of these words, to create a list of unique IDS collected using text oracle contains the query as follows: (pseudocode)
    for SPLIT.word in "snowboarding", "Church".
    SELECT SCORE (1) NIVEAU_RECHERCHE,
    NO_MATRC,
    NO_NOM_
    OF GR_OT_NOM_ASSJT
    WHERE CONTAINS (name, SPLIT.word, 1) > 0
    UNION
    SELECT SCORE (1) NIVEAU_RECHERCHE,
    NO_MATRC,
    NO_NOM_
    OF GR_OT_NOM_ASSJT
    WHERE CONTAINS (name, ' SYN('||)) SPLIT.word: ', GR_THESAURUS)', 1) > 0
    UNION
    SELECT 100 AS NIVEAU_RECHERCHE,
    NO_MATRC,
    NO_NOM_
    OF GR_OT_NOM_ASSJT
    WHERE NAME LIKE '% "| SPLIT.word | '%'

    so of course I have to untangle this UNION to remove duplicates

    Anyone here sees a way out of my situation? A way to make the loop in a select (use with and such) then
    Just add a select distinct NO_MATRC, NO_NOM_ from)

    I tried, but I'm out of ideas so I thought that some guru here might have the answer ;)

    Thanks in advance for any advice

    See you soon

    You might end up with something like the XML below, ideally as binding in the query.

    SELECT SCORE (1) NIVEAU_RECHERCHE,
    NO_MATRC,
    NO_NOM_
    OF GR_OT_NOM_ASSJT
    WHERE CONTAINS (name, e
    Church of snowboard

    transform ((JETONS, "{", "}", "AND"))
    transform ((JETONS, "{", "}", "OR"))
    turn ((JETONS, «SYN (",", GR_THESAURUS) ', 'AND'))
    turn ((JETONS, «SYN (",", GR_THESAURUS) ', 'GOLD'))
    transform ((JETONS, «?)) {","} "," AND"))/seq >
    transform ((JETONS, «?)) {","} "," GOLD"))/seq >

  • Performance issues and options to reduce the loading with the Oracle text implementation

    Hi Experts,

    My database on Oracle 11.2.0.2 on Linux. We have Oracle implemented for the fuzzy search. Our oracle text indexes are defined as sync on commit that we cannot afford to have stale data.  Now our application done literally thousands of inserts/modifications/deletions of these columns where we have these Oracle text index defined. Thus, we see a significant impact on performance because the oracle text synchronization routines is called on each commit. We do nightly index optimization (optimization full every night at 3:00).  The text index oracle internal operations are appearing at the top of the sql page in our AWR report and fears it causes a lot of load on the DB.  Since we do optimization of the complete index once during the night, I think I should change that, and if I do, he's going to help us?

    For example, here are some data of AWR report my one day:

    Time elapsed (s) Executions Time by Exec (s) % Total % CPU %IO SQL ID SQL module SQL text
    27,386.25305 4410.0916.5015.829.98ddr8uck5s5kp3Start ctxsys.drvdml.com_sync_i...
    14,618.81213 9800.078.818.3927.7902yb6k216ntqfbegin ctxsys.syncrn (: idxownid,...)


    More top sql full text:

    ddr8uck5s5kp3begin ctxsys.drvdml.com_sync_index (: idxname,: idxmem,: partname);
    end
    02yb6k216ntqf

    begin ctxsys.syncrn (: idxownid,: idxoname,: idxid,: ixpid,: rtabnm,: flg); end;

    Now if I do optimization of the complete index that more often, and not only once night 15:00 will be this average, the load on DB sync on commit will decrease? If Yes, how many times should I optimized and the optimization itself does not lead to a load? Can anyone suggest?

    Thank you

    OrauserN

    It's to you which values you want to experiment.  Since 1 G, which is the same as 1024M is the maximum I could try that assigning to an index and see what effect it has.  You can use the same AWR report that you used previously and compare performance.  To determine when paging depends on your operating system and what tools you have.  Another option might be to use TRANSACTIONAL, that allows searching for unsynchronized lines and allow you to synchronize every five minutes, like Herald suggested, without any latency problem.  You can read about it here (scroll down to transaction):

  • Problem with the Oracle text markup

    Hello

    I have a problem with the Oracle text markup.

    I am looking for keywords in a text which is composed by a question and answer.
    Here is the structure of my text:
    & lt; div class = 'question' & gt;
    & lt; a & gt; the title of my question & lt; /a & gt;
    & lt; div class = "reply & gt;
    content of response
    & lt; / div & gt;
    & lt; / div & gt;

    It is possible to search those keywords in the question or answer only. For this, I use the stored procedure:

    {call CTX_DOC. MARKUP)
    index_name = >?
    textkey = >?
    text_Query = >?
    restab = >?
    query_id = >?
    startTag = >?
    (EndTag = >?)}

    _with these parameters: _

    index_name = < my index >
    textkey = < id for the search text >
    text_Query = < a query containing the keywords >
    restab = < a table SQL to store the marked text >
    query_id = < id >
    startTag = ' < span class =-"highlight\" >. "
    EndTag = "</span >.

    The markup should be done only in the place you want (question, answer, or both).
    The markup is good when I search a keyword throughout the text, in the question or answer only.
    * If I search two key words in the question or answer, the markup is bad *.

    _Example: __
    I am looking for the words "* Internet *" in question only.
    Here's the query passed to the stored procedure:
    + * text_query * = 'service & internet' INPATH (//div[@class = 'question'] / has) +.

    In the question, these words are well marked.
    In response, only the first word is marked.

    * Why the first keyword is also marked in the response while the query specifies a search in question only? *

    The same problem appears when I search for the same keywords in the response only.
    In this case, in the answer, these words are marked as well.
    In the issue, only the first word is marked.

    Thanks for your help

    Edited by: user11088931 Apr 21. 2009 06:17

    Try text_query = (service & internet) INPATH (//div/a)

    Single quotes in a query do nothing. I think that your request has been treated as

    Service & (internet INPATH (//div/a))

  • EA6500 will not send/receive the cell text and multimedia

    I just took an EA6500 on clearance.  It works very well for all applications except text messaging.  I can send and receive texts and multimedia on all other WiFi connections I use, but it does not work on my EA6500.  Is this standard, or is there a place I can change the settings?

    We are with US Cellular by using an old Samsung (not sure of the model), two S7s and an iPhone 6 (more or sPlus... not sure), more on WiFi an old M bike, only.

    Thanks for any help on this.

    Natalie

    Cell phones use the cell signal from the phone to the normative texts and the data connection of the phone for multimedia content.  None of this happens on WiFi.  It does not work on all other WiFi connections, you are confused.  Text works when you have cellular signal and the works of content media when you have a valid data connection.  Maybe it would help if there is an application that transmits over the internet, then on mobile networks, but not using the original text/sms on the phone app.

  • How to change the white text and more light colours of text and illustrations to deep colors or provide a deeper black outline, so that they are legible?

    I noticed that the illustrations and white text are not readable as well as light colored fonts that I use. I have consulted with Microsoft and other help sections various areas recommended, but impossible to find what is the problem and how to solve these problems. In order to clarify, for example, if I go on a site that displays white text anywhere on the screen, or illustrations in white, I can't read or see anything even if I do expand. I tried to innovate in following things suggested in onlne Microsoft Help related to the resolution section, but can't find anything on this specific problem when I do a search. I tried to change my display resolution settings, change the background color of my screen, themes and even the font colors, but nothing changes for the problem. I also noticed that any file in my computer appearing in any color of light is also hard to read. I must not do something correctly, but I don't know what. It's a pain for example, when I go to a site, and the white text and illustrations appear, but do not have any black outlining. Magnification just leads to the same result. Can anyone identify which is the problem, the settings on which I should be focusing and provide instructions on how to fix this?  I use Windows Vista Home Premium and I am a layman when it comes to computers.

  • Windows 8 cursor jumps in the existing text and continues to type here rather than the finish line that I am on, anyone else spotted the same thing?

    Just upgraded to Windows 7 to 8, using MS Office Word 2010, worked well on Win 7, but now type text and the cursor suddenly jumps into the existing text and continues typing, rather than the finish line that I'm on.  Thought, I was accidentally touched for touch pad or other keys, so now consciously look for this but can find nothing on my part.  Have experienced it before with a processor OS Linux and Open Source, when the OS has been updated.  Think there may be a loophole to WIN 8.  It also happens when keying in the screens like this, that has happened twice while here. Someone else spotted the same thing?  Or is it just me?

    Also, anyone know how to disable "Open Tap" on the Mouse touchpad of the notebook, its annoying, I could disable in WINDOWS 7 but cannot know how Win8.

  • Customize the appearance of the attribute - text and control

    The OPM user guide provides guidance on how to customize the text (issues, labels, etc.) and controls: here

    However, the OPM IDE does not allow the two to be customized at the same time. If the 'IsHTML' box is ticked then the CSS fields are grayed (and occult content precedent).

    Is it possible to customize text and control for the same attribute style?

    In order to make the two guests of question HTML tagged and change the styles/class for the control, you must change the models in speed and/or CSS files directly.  Guide the developer Oracle policy Automation for your version to reference:

  • iPhone battery 6 draining on the home screen and locking

    I've read other posts on the drain of the battery on the iphone but that you did not find an answer that reflects my situation.

    Relates to the iphone 6, ios 9.3.1 64 GB,.

    I took my phone this morning and pressed the home button to check the remaining capacity before getting ready for the day.  It is 79%.

    I ask without opening any application or even unlock.  As usual, the screen goes black after a few seconds.  I go back an hour and a half later, and now it's 23%.  So I check the battery use it it shows as home and lock screen used 97% of the power of the battery since my last load.

    Why the drain?  It doesn't drain as quickly when I watch a video and it was just the home button to check the remaining power.

    The percentage shown is not since the last charge. It's usage in the last 24 hours. It could have been 5 counts at the moment.

  • Invert the colors in the layer text and background

    Hello

    Can someone please guide me through do reverse my position.

    Basically, I created an outline of buildings in the background using the pen tool - this part is fine. Then I had filled white buildings inside and outside with black.

    Then I have the text layer. Now, I want to have the text overlapping the two portions of the black and white of the background while being in the Middle, and the problem I am facing is I'm trying to make sense of the texts that overlaps the black area to be white and black when he rides the white area.

    So just a summary:

    Question #1: How can I go to do this inversion of color?

    Question #2: Just another question - is there a better way to create sharp backgrounds? I basically used the pen tool to create rectangular shapes, a little inclined to the buildings in the background - the area selected and filled with the foreground color, which, in my case, I chose white. I left at 0 Pixels and checked anti-aliasing when I chose the area by the way. I'll get this pattern printed on a black shirt, then I want the lines to be as sharp as possible, if someone can you please advise me if I don't do something right in the above. Kindly let me know if there are better ways to do it as well.

    I thank you all in advance and have a nice day!

  • Problems with the HTML text and cutting!

    Hey everybody,

    This is my first post a lot! I have a very simple question but frustrating, I cut text in illustrator (object > slice > make), then to make this text in HTML (slice Options) text. Then I export my picture with other pictures behind this text using the 'Save for Web and devices' option to find that the "HTML" text has moved all art behind it!

    I have attached a picture of a very basic example of what is going on, as you can see all around this text has been moved, the text does not stay on top of the work behind it?

    screenshot.jpg

    I would appreciate any help on this problem, probably very easy to solve!

    Thank you very much!

    There is nothing "to"stay on top"- a slice is a slice and they are prepared automatically side by side. You can only assign a background color. I strongly suggest do you a little reading on HTML / CSS first. No offense, but you are using the wrong tool if you think that I could remotely anything like usable HTML code...
