Queries in Exadata

• Exadata to no Exadata Data Guard

  Hi all

  I was wondering if its possible to have a custodian of data between an exadata at the JRC to a single instance of Linux server with a ZFS storage pool.

  I have experience in a RAC standby single instance with data protection, it is not my problem.

  What I was I was wondering if there is a question in this configuration with the exadata, in theory is a database platform Linux with the support of the Supreme Constitutional Court

  Since I have the HCC support with the ZFS storage pool, I think it's possible.

  Thanks for any advice.

  HI THE CMF.

  It's certainly an interesting use case: have a database Eve supported ZFS device in order to use the HCC when Eve is opened.  Of course, a single ZFS supported by the database instance will be considerably less ability than your Exadata, so I guess it will be a read-only reporting system than a true disaster recovery environment.  If you plan on running large queries on ZFS - backed HCC data, keep in mind that, unlike Exadata, decryption of the HCC is not unloaded to storage, then the available CPU of the server database to manage the workload increased.

• Impact of Exadata database

  Dear gurus,

  Please share your valuable comments what will be the impact on database queries and sql on Exadata full rack when disk_asynch_io = false and filesystemio_options = asynch or setall?

  As of now I have not test machince on Exadata to test above scenerio, so just wanted to know your point of view? Pleae share.

  Thank you

  All right

  When you use ACFS as the file system that is basically like a dumb file system, you lose most of the benefits of Intelligent storage. Therefore, it is quite possible that dbwriter will return to the use of the standard i/o system calls to access the files on acfs. Note that you referenced

• major differences of exadata database, listener, process than the normal RAC environment?

  I would ask for any input about the major differences of exadata database, listener, process than the normal RAC environment.

  I know now the exadata have not only SCAN listeners, but many other listeners. expert here can provide clarification?

  Thank you

  All the right questions... Welcome to the world of Exadata.

  These are questions that could get into a lot more detail and discussion than a forum post. At a high level, you certainly don't want delete all indexes on Exadata. However, you need to index and an indexing strategy will change on Exadata. After you move a database from one not Exadata Exadata environment you are probably more indexed. Indexes used for OLTP transactions real - looking one or a few lines among others will usually quickly with an index. The index used to avoid a percentage of records but always returning number of records can often be moved. On the index depends on the nature of the workload and your application. If you have a control on the index, then test your queries and DML with the index (s) invisible. Check your implementation plan, the columns io_cell_offload in v$ sql, smart scan wait events to ensure you get intelligent analysis... and see if the smart scan is faster than using the index (s). The real-time SQL Monitor is an excellent tool to help with this - use dbms_sqltune or grid/cloud control.

  Parallelism is a great tool to help still speed up queries and direct path loading operations and can help prompt smart scans... but use of parallelism really depends on your workload and must be controlled using DBRM and the parallel init parms, possibly using same parallel declaration put on hold, so it is not overwhelm your system and cause concurrency problems.

  If you have a mixed environment of workload or consolidates databases on Exadata so my opinion is IORM plans should certainly be implemented.

• SQL Tuning for Exadata

  Hello
  
  I would like to know specific to Oracle exadata SQL Tuning methods so that they could improve the performance of the database?
  I am aware that oracle exadata works with Oracle 11 g, but I would like to know weather there any s w.r.t. to SQL tuning on exadata?
  
  concerning
  Sunil

  Well, there are some things that are very different on Exadata. Remember all the standard Oracle SQL tuning you have already learned as Exadata runs the code of database 11g standard, but there are many optimizations that were added that you should be aware of. At a high level, if you make the OLTP type work you should try to make sure you enjoy Exadata Smart Flash Cache that will greatly accelerate your small I / O of the but long-running queries are where appear the great benefits. The high level tuning approach for them is the following:

  1. check if you have found smart Scans.
  2. If you are not, difficulty that never prevents them being used.

  We have been involved in somewhere between 25-30 DB now machinery facilities and in many cases, a little bit of effort changes performance considerably. If you get only 2 to 3 X improvement on your previous platform on these long term requests you get probably not all the benefits of the Exadata optimizations. So the first step is to learn how to determine if you've found the smart analysis or not, and what parts of the statement. Wait events, session statistics, V$ SQL, SQL monitoring are viable tools that can show you this information.

• A few queries on the design of PA

  Hello

  I'm working on a design of PA (1930-1990 MHz) 4W using Freescale LDMOS MW6S004N transistor (attached sheet). It would be very useful if someone could shed some light on the following queries;

  1) I've traced the I - V curve and the Vgs as 2.77V (Vds = 28V, ID = 50mA) and biased the transistor with solenoid and BIASTEE elements to watch the gain and stability. But the gain is only around 7dB @ 1960 MHZ (while the data sheet shows a gain of 18 dB). Also, looking at the factors of stability, a MU1 MU2 is less than 0 and K<>

  Yes, why is the only model not give the gain - without correspondence as other peripheral circuit?

  Why is he unstable? It should be like that?

   

  2) but when I increase the tensions of polarization, I see improving gain up to 10dB and then drop on a further increase of the voltage input/drain. So I'm not supposed to gain the necessary to the data sheet specified bias point?

   

  3) in the datasheet, page nr.8, Zsource and Zload for the test circuit are specified for 1930, 1960 and 1990 MHz. So if I create the test as shown circuit (with input output matching and lines of bias) and make a measure of ZIN at the source and the load of the appliance, should not I should I get accurate impedances at these frequencies? This should be done in a scheme with infectious myonecrose or OMN only and without the device? 

   

  4) should I see the exact data sheet specified impedance if I do a pull source or load pull in the original circuit using LTUNER elements?

  5) , How can I specify the magnitude and angle in the LTUNER element when I have a point of impedance in R + jX format?  I have attached a screenshot of an example of AWR tutorial, but I don't see how the conversion was performed at mag

  Pointers to these queries will help a lot! Thanks in advance.

  1 & 2. It is a power FET; It has a very low output impedance; the datasheet shows the production capacity is 25pF.  If so, I don't see how you get the desired gain when he puts an end to the output of 50 ohms.  In addition, the specification of gain run 4W on.  Look at an angle specified as class AB, so the small gain may not match upward with specifications, either.

  3. If you build the circuit as described, I think lets you get results close to those that they specify.  You can join the project?

  4. you can ask Freescale, but my guess is that nothing will be exact.  Follow patterns of the specific formulas, and despite the flexibility permitted by the various parameters on a FET, it is difficult to get behavior exactly measured in all conditions.

  5. LTUNER is probably not the right choice, if you plan to do harmonic analysis balance; HBTUNER may be preferable because it allows to bypass the harmonics and send power to the rear.  You can reduce the number of items in your base using HBTUNER2test circuit, which has built-in te through.  If you double-click on one any of these elements of tuner, you will see the description of the Mag and Ang parameters, which States that they are for Gamma.  So write some equations and convert z to gamma.  The AWR design environment allows to describe the functions and can handle complex variables. For example, see the image as an attachment.

• Slow queries in executable on the Surface of Win8

  Having a problem with an executable file using LV 2013 and connectivity toolkit.  Exe works fine on my Win7 32 bit machine and the code works well in development on Win 8 Surface mode.  Functioning as an EXE file on the same winning 8 Surface is extremely slow (factor of 20 or so slower that the mode of development on the machine either EXE or on Win7 machine).

  I see a variety of positions "to do something special with EXE using connectivity tools" but they are all<2006 and="" the="" exe="" works="" fine="" on="" win7="" machine="" so="" i'm="" thinking="" they="" "something="" specials"="" are="" not="">

  Pointing to a localhost MySQL database. Database contains about 15 tables and no table has more than 10 k lines.  Does nothing exotic in queries and there is not many of them, like going from databases. Multiple queries (but maybe not all of them, I'm not sure) involving different tables are slow.

  Have tried (all to no effect):

  1] connecting to a remote instance of MySQL with the same data

  2] recompile the EXE file

  [3] restart of the Surface

  Am trying another Surface. Will also try to compile on the Surface (it is currently compiled on Win7-32 and settles to the Surface of Win8 64).

  Any thoughts?

  Solved.  It turns out that it was a combination of a string of bad connection and not degenerated errors and multiple reconnection attempts.

  It was useful; I'll post it here in the interest of sharing: https://www.connectionstrings.com/mysql-connector-odbc-5-2/

• RE: WINDOWS XP SP3 of queries sent October 2, 2010 dear Sir,

  RE: Queries WINDOWS XP SP3
  Envoy on October 2, 2010
  Dear Sir.
  We just installed Service Pack 3.  Now several changes
  have taken place, we want to reverse.
  1. all records have the beginning with FILE menu command
  FIND the best choice (in bold).  That means ENTER key opens
  Search, not the file directly.  We have our own system of
  storage file in subdirecories and do not want to use
  'My documents', "myComp" and other stupid names.  How can do us
  OPEN as the first choice?
  2. when to use CTRL + F to search for a name of text inside file
  a file, the window opens in the same position as the record
  to be examined.  It also closes this folder later.
  How can we have RESEARCH to appear as a separate window, while
  NO previous windows closed?
  3. the default icon for folders is a Manila folder with
  a lot of very small bunk symbols.  How can we define the
  default to a folder empty manilla everywhere?  The
  "applies to subsequent records" does not work.
  4. some record fields (columns) appear very light
  colour, white and tinted white.  This is a nice feature
  We want to use, but it is difficult to distinguish no difference.
  How can we make the differential color stronger?
  5. for the connection of an external hard drive, it automatically
  "autoplays" and a menu comes to "choose action".  We
  Oly use it to back up = data.  How can this unwanted wizardly
  assistance to shut up?
  6. in the browser, the message "Intranet settings are now".
  turned off... "appears every time and takes another bar
  across the width of the screen.  How can we delete this
  message permanently?  We have no Intranet connection.
  7. when clicking a *.pdf file suddenly the first order
  in the menu file is replaced by "open with Adobe Reader 9.
  How can I remove this annoying interference and simply do not have
  'open' option at the top of the page?
  8. from time to time, we record our voices using Microsoft «»
  Tape worm 5.1 SP3 "and headphone\mike together.  But the
  micro alive all the time 24/7.  Where can we find a
  button to turn off the microphone?
  9. in case of a 'research' reviews movies automatically to
  large icons, while we only use the format of "details".  How can-
  avoid us this constantly and everywhere?
  10. in opening the files, there is a subtle broken white color
  several fields of details.  It is strange that not the same
  fields have the same color.  While the colored backgrounds are
  attractive, we would lke more control and stronger colors.
  How we handle this view
  ?
  11. two of my folders have fonts colours blue and yellow, all
  others are in black.  Seems to have no control over that.
  How can I change the font color of the names of files and folders
  ?
  12. When you change the folder icon, it records as a new date
  changed, but no data is changed.  We now *.htm and
  their associates * _files on different dates. How can-
  We store the last modified date when data are
  in fact, only edited?
  13. in EXCEL3000, when two cells are merged in the two lines
  and the alignment of the text is located in the 'Center' then the other
  individual cells along these two lines, all texts are centered
  (including the number of line along the left border) and cannot be
  moved to the 'low' or 'top '.  How can we remove all «»
  alignment of the line '?
  14. in EXCEL3000, the cells seem to have a very slight tint
  (off-white) as the color field.  In edit mode, they turn
  more bright white, includng all other cells that have been
  recalculated after change data in a related cell.
  This lasts until the screen is refreshed.  This only happens
  in some sheets in the same workbook, but no color change
  in the other sheets.  How this attractive feature can be
  controlled in all sheets and how color can be set to one
  stronger tint?
  15. in EXCEL3000, the appearance of color of a spreadsheet is
  controlled by the definition of the location of the color
  palette.  But this can be changed arbitrarily by the user and
  isn't it the same in other versions of EXCEL.  How can we be
  certain that a proposed color actually appears even if
  the file is viewed by another user, or on another computer?
  16. in Internet Explorer v8, when downloading files from
  Internet, the meter on the bottom left starts to
  "Download (1.32 MB 6.35 KB): http://www...". "but then
  freezes and does not increment until the product for download.
  Sometimes it freezes at other values.  Fact that occasionally
  the counter advance at a rate set at full value.
  If it is a bug, can it be fixed?  If it requires an action,
  What do we do
  ?  When the whole numbers are displayed, the two
  decimal places are disappearing.  It is good scientific practice
  ALWAYS show the degree of accuracy, being two decimal places,
  including the zeros.  The mixture of display KB and MB in the
  same statement is NOT good scientific practice.  All units
  must be the same.  To display two decimals in kilobytes
  is insignificant and meaningless.  It would be preferable to view only the
  Megabytes, then to THREE decimal places to take account of
  Kilobytes.
  17. in EXCEL3000, using forms automatic drawing compounding
  several surfaces that overlap, the command "go to the front" and
  "go to the rear for" works well.  But the option 'down' and 'go '.
  superior"do not seem to work.  There is no way to find out
  in which order the drawing folios are stacked.  What makes
  the shading of unpredictable stacked surfaces.
  18. in WORD3000, the cursor blinking on the insert is sometimes
  very short, less than half of a strong letter.  Other times it is
  all the way up.  He's still very thin and not easy to see.
  How that can be controlled
  ?
  19. under WIN - XP, using "save under" a file name can be suggested
  or a new typed in.  By then changing the subdirectory,
  Sometimes the name turns into an existing file,
  already highlighted in this new subfolder.  Expected not
  This change, pressing "enter" of the old file is overwritten
  and its lost data.  How can it be avoided in all cases?
  20. in start the computer, it always displays a message
  "Cannot open the scanner program.  But I do not use a scanner.
  How this message got there and how to stop
  appearing in the future?
  21 when a folder is renamed, its 'Date Modified' passes to
  today.  But all subfolders automatically change their
  "Date of creation" in today.  It is a significant loss of integrety
  all of the files involved.  How this can be fixed or
  prevented from happening again?
  22. when a case is its icon has changed, the research"(CTRL + F)
  present the old icon.  How can we make the icon of a file
  the same appear everywhere wherever it is displayed?
  23. How can I make the sound composition, as the numbering mode
  beeps?
