• I found the show/hide button toolbars, but you should know how to REMOVE toolbars that appear on this list?

  I found the show/hide button toolbars, but you should know how to REMOVE toolbars that appear on this list?

  Is attached a screenshot of my screen with the context menu to show/hide tabs. I want to delete some of them and let others. Please help me to know how. Thank you!

  Hmm, maybe this "one-time" imported into the new preference? Try this:

  (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (2) in the search above the list box, type or paste the cust and make a pause so that the list is filtered

  (3) double-click the preference of browser.uiCustomization.state and the content must be highlighted in a small dialog box.

  (4) copy the whole line and paste it into Notepad and save it as a backup.

  (5) in Firefox, click on the button '3-bar' menu > developer > Notepad. Remove the comment that appears and paste data preferably, that must appear on a long line. Click on the "Pretty Print" button to make it more readable.

  So I hope that you can spot the extra toolbars and change them out, taking care to preserve the commas between the elements.

  I don't have the extra toolbars in mine, but I copied and pasted back this spaced format and Firefox was able to handle it well. I went into customize and moved a button, and when I left, Firefox has rewritten the preference set as a single line. Assuming that yours works fine, then you can get rid of the backup from step (4).

• Satellite P300 - 219 PSPCCE - what should be the optimal heat of CPU?

  Hello there;

  I use for my laptop Satellite P300-219 (PSPCCE) newly bought about a week now. When you type I can't help noticing, the place where I put my left hand, I want to say the empty space to the left of the touchpad, feels much too hot. I looked for the manual and I have learned that it is where the CPU.

  Then I searched for a way to measure the heat of CPU, and after having tested some programs with too many different measures, I led to believe that the 'CPUID hardware Manager"gives the best results, after you set the correct value TJUNCTION.

  Here are the steps I get today while typing this message:

  ACPI hardware monitor
  Temperature 0 45note ° C (112 ° F) [0xC6E] (THRM)

  Intel Mobile Core 2 Duo T6400 hardware monitor
  Temperature 0 56a ° C (° F 132a) 0 x [31] (Core #0)
  Temperature 1 54a ° C (° F 129a) 0 x [33] (Core #1).

  Monitor hardware ATI Mobility Radeon HD 3650
  53A temperature 0 ° C (° F 127a) (GPU Core)

  Hardware Hitachi HTS543232L9S monitor
  Temperature 0 37â? Â ° C (98A? Â ° F) (0 x 25) (Assembly)

  From now you mind, windows taskbar indicates that I use roughly about 15 & 35% CPU. After a little use, I even though the CPU heats by a maximum of 69a ° C.

  The truth is, I don't know what to do with these readings, is my laptop which works very well, or he has problems? Could someone please tell me what should be the optimal level of heat for a P300, or where I can learn?

  Thanks in advance.

  Hello

  In my opinion, everything is ok with your laptop, buddy and the temperatures are quite good. Don t be to worry about this!
  If your laptop could overheat, it would have to close or freeze immediately. If this isn't the case, everything is ok with the temperatures.

  What you can do is to change the cooling method in Windows power management. Here, you change between performance and battery optimized cooling.

  By the way: you should also clean your laptop at any time. I clean my laptop every 3-4 months using a jet of compressed air. This blows the dust from the cooling fans.

• Tips on optimizing the performance of table.

  Hello

  I read several article on optimizing the performance for the table. Finally, I settle on a strategy to implement, but I have a few questions.

  Let's say we want to display a wide range of data in a table. The number of lines displayed on the screen is n = 25.

  For each VO displayed in table form: Open model project->->->-> Data Model Instances to View object Data Model Module of Application -> select your view object-> press the modify... button-> Tuning

  • For best performance Oracle ADF Performance Tuning Documentation indicates that in lots of field must be set to n + 3
  • The scope of the queryoptimizer indicator should be the value + 3, so if n = 25, FIRST_ROWS_28 FIRST_ROWS_n
  • By default, access is set to Scrollable, which is OK as long as you aren't iteration in a large data set, but if you are, then you must change the Access Mode to the Range Paging
  • Set the size of the beach to n + 3

  Q1: What is the reasonable maximum for a set size? Client wants to display huge table as 200 lines that is not really usable, but it's what they want. I was wondering if the definition of the size of the beach at 203 is a reasonable value, or if it is too high.

  Q2: I have really not understand the purpose of the indicator of QueryOptimizer even after reading the documentation. Is it okay to put it at FIRST_ROWS_203 if your batch size is 203?

  Thank you

  JDev 11.1.2.4

  What version of jdev we are talking about?

  Is the table in paging mode (+ 11.1.1.7)?

  Q1 Yes), the tip is still standing, then set-203. The reason is that the table will display 200 lines that you need to load them in any case. In this case, it is best to load them into a round trip. a smaller rangesize then the number of visible rows in the table means more then 1 trip on the server and the db.

  Q2) the query optimizer indicator is just passed to the db which then decides to use it or not. The indicator shows the db to deliver the first n lines of results as soon as possible. If you have large result sets the db can provide the result set when it comes always collection more data FRO the game results in the background. This will display the fastest page to the user.

• Need a tool to investigate SQL performance

  If anyone can share a tool to study the SQL performance?

  Hello

  I don't know if this is a good place but you can opt for Quest Toad, which is one of the most common SQL configuration tool.  However, if you are interesting in SQL performance specifically to your DB, then you can consider SQL tuning packs that come with DB Oracle enterprise edition (careful if you use the standard edition).

  In addition, Oracle has a very nice set of scripts allow you to download... but you must have an account to the Oracle support:

  Well, the other forum you mentioned is the Korean equivalent of the English forum.

  You have already discovered, it is not controlled to many users. I didn't know that it exists at all.

  In general it is to you where you ask your questions. All for one here are driven by the community and some employees of the Oracle, you cannot wait has answered all your questions. If you really need to answer you go through paid support.

• should we run catbundle.sql after creation of DB?

  Hello, I have installed oracle 11.1.0.7 and installed the patch (10249534) CPU 2011.
  
  I intend to create the database after a few weeks. So after you have created the database, should I run the scripts below?
  Given that this is part of remedial education.
  
  
  * 3.2.2.1 loading modified the SQL files in the database *.
  The steps following loading changed files SQL in the database. For a CCR environment, perform these steps on one node.
  
  For each instance of database running on the Oracle home being patched, to connect to the database using SQL 'More'. Connect as SYSDBA and run the script catbundle.sql as follows: *.
  
  CD $ORACLE_HOME/rdbms/admin
  sqlplus/nolog
  SQL > CONNECT / AS SYSDBA
  SQL > STARTUP
  SQL > @catbundle.sql cpu apply
  SQL > QUIT
  Execution of catbundle.sql is reflected in the sight of dba_registry_history by a related line of series CPU bundle.

  Hello!

  You must run the catbundle.sql only for databases created before the application of the CPU.
  If you create a new database after the application of the CPU on the ORACLE_HOME, you don't need the script to run catbundle on it.

  Best regards
  Norbert
