• Commit to taking a lot of time for the update statement to bulk - 11 GR 2

  Hi team,

  We have a source table, which is the main table for our application.

  When I commit a transaction after update block, it takes long about 2 to 4 minutes.

  I don't understand why it takes too long...

  Could you please help me on this fix, please...

  It's the details on the table,

  Total number of records: 35 M record

  Validation interval: 500 records / commit

  Total scores: 3

  total number of columns: 95 - including primary, unique and foreign key columns (all columns will be updated for each update because update from the app online)

  Total no of the foreign key columns: 12

  Unique key column: 1

  Total index: 27 ( including the key index foreign 12 + 1 + 1 index of primary key Unique key index )

  example of update statement,

  UPDATE DIRECTORY_LISTING_STG
  SET
    COLUMN_1 = :VAL_1
    .
    .
    .
    COLUMN_94 = :VAL_94
  WHERE RECORD_KEY = :P_KEY_VAL;

  line-by-line UPDATE is slow by slow transformation

  In Oracle no other session can 'see' upgrade from uncommitted changes.

  The only way to significantly reduce the elapsed time is to have only 1 UPDATE & 1 COMMIT!

• SQL error: ORA-01840: value not long enough for the format of the date of entry

  It is a delete SQL in a driver of demand, which gives no error, but does remove all the lines either. I have converted the removal 'from' to ' Select * ' and may see the following error:
  
  Select * FROM PS_GPDE_DV_TRIG40 WHERE EXISTS (SELECT FROM 'X'
  PS_GPDE_DV_ELIG_MO ELG WHERE ELG. EMPLID = PS_GPDE_DV_TRIG40. EMPLID AND
  ELG. EMPL_RCD = PS_GPDE_DV_TRIG40. EMPL_RCD AND TO_DATE (TO_CHAR (ELG. PRD_END_DT
  "YYYY"). TO_CHAR (ELG. PRD_END_DT, "MM"). '01', "YYYY-MM-DD") =.
  PS_GPDE_DV_TRIG40. GPDE_DV_EVT_EFFDT AND ELG. CAL_RUN_ID = "CAL_0812")
  Error report:
  SQL error: ORA-01840: value not long enough for the format of the date of entry
  
  
  The interesting thing is that if I attach a condition of emplid, then the SQL above does not give an error and return lines:
  
  Select * FROM PS_GPDE_DV_TRIG40 WHERE EXISTS (SELECT FROM 'X'
  PS_GPDE_DV_ELIG_MO ELG WHERE ELG. EMPLID = PS_GPDE_DV_TRIG40. EMPLID AND
  ELG. EMPL_RCD = PS_GPDE_DV_TRIG40. EMPL_RCD AND TO_DATE (TO_CHAR (ELG. PRD_END_DT
  "YYYY"). TO_CHAR (ELG. PRD_END_DT, "MM"). '01', "YYYY-MM-DD") =.
  PS_GPDE_DV_TRIG40. GPDE_DV_EVT_EFFDT AND ELG. CAL_RUN_ID = "FM_CG_0812")
  and emplid = "1234"
  
  now, if the number of lines is identified (by giving more number of emplids), it begins to give the error when the number of rows returned is greater than about 30. It is completely independent of what employee is used, so there is no question of data dependence.
  
  Function optimizer cost is off and a subquery nest is off on the init.ora file

  Explanations would be welcome!
  
  Thank you

  I think it is question of data combined with a not very sensible date format mask (it could fail when the null data, because of your concatenation with '01' and work when not null data).
  Have you tried with a simple TRUNC?

  Your code:

  ...TO_DATE(TO_CHAR(ELG.PRD_END_DT, 'YYYY') || TO_CHAR(ELG.PRD_END_DT , 'MM') || '01' , 'YYYY-MM-DD') =PS_GPDE_DV_TRIG40.GPDE_DV_EVT_EFFDT...
  

  After change:

  ...TRUNC(ELG.PRD_END_DT , 'MM') =PS_GPDE_DV_TRIG40.GPDE_DV_EVT_EFFDT...

  Step 1: Please do all the same underneath if you did some before as is often total
  a process that solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
  below.
  
  Then, work your way through these - don't forget the drive might be bad, could be a coward
  cable or slight corrosion on the contacts (usually for a laptop) and other issues.

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
  ends. Remove and replace, do not just tight. For laptops, you can often clean power and
  contacts data with a pencil eraser.

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
  manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

  ===============================

  Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
  Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
  do it right.

  Did you follow the Troubleshooting Guide for the reader who still does not work? There are
  the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

  Check with your Maker system and a device for the two possible firmware updates and
  the correct registry entries for your car.

  Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive

• SQL Developer 3.0 EA 1 Advanced support for the type of data in the unit tests

  Hello
  
  According to SQL Developer 3.0 EA 1 New Feature List (http://www.oracle.com/technetwork/developer-tools/sql-developer/rel3-featurelist-ea1-166831.html#ut)
  the EA 1 version 3.0 supported advanced data types in the unit tests. This means support the ANYDATA and RECORD types? I installed version 3.0 of EA 1 to CentOS linux, but it seems that those advanced types are not supported yet. When I try to add a unit test for a function that returns the record type, I get quick error: "the return of PL/SQL RECORD type is not supported. Cannot test (function_name) because 1 arguments have not supported for types". Also if I try to unit test procedure which parameter is of type ANYDATA, I get quick error: "the type UNDEFINED P_DATA argument is not supported. Cannot test (procedure_name) because 1 arguments have not supported for types". Are those advanced data types supported in SQL Developer 3.0 FINAL version?
  
  Thank you

  Hi Mikka,

  Only simple PL/SQL records are currently supported i.e. those containing no optional or repeating components and where all components are themselves supported. This restriction is in place, due to the fact that we are using JDBC as a parameter mechanism which does not directly support the passage the PL/SQL record type.

  ANYTYPE and ANYDATA are currently not supported because they have a dynamic value type and must be set programmatically. In the future, it would be possible to support these via the dynamic value and and validation features.

  This will remain for the final version.

  Kind regards

• My MBP with retina display has no top file, but storage information still show a lot of memory being exhausted by audio, photos and movies.

  Where are all these "hidden audio, photographs and films that take about 3 GB of space from my hard drive? I am naïve.

  This view will be incorrect until the Spotlight indexing your drive. In addition, it is only an effort to classify the files types are known by their file extension. Thousands of files on the computer, however, will only be classified as 'Other' because they did not have a type that falls into one of five or six available categories. If you want an accurate display of disk space then: press command-I to open the window read the information. In the top panel is a visualization of the status of your drive: capacity, used and available. It's everything you need to know. If you want information on the types of files and their location, and then use a tool such as OmniDiskSweeper or GrandPerspective.

• Whenever I load a file (.jpg) image in firefox, it shows a grid of tiles for the empty border. Is there a way I can change it to a solid color?

  It has been a solid gray in some older versions of firefox (14 or earlier), so it must be customizable.

  For now, it's showing a grid made up of squares white and cyan checkerboard.

  Already tried to add "background-color: #00000;" to userchrome.css. He has nothing.

  Thanks for trying to help, but I don't think that you have taken the trouble to read the question at all. Flash has no effect display jpg files because it is not even running, and do all the other plugins unless they specifically target the JPEGs

• Will we still have access to Auto rig for the custom character content that we create in the 3rd party software like Maya or Blender 3D?

  We will still be able to take the content of custom character that we modeled ourselves, instead of the Assembly in the fuse and use the automatic Rigger for joint investment and weighting of the skin?

  The Rigger automatic, as this was the Mixamo, is the best solution I've seen for character rigging auto and mapping weight skin.

  It takes a few hours of tedious technical work and simplifies it in 2 minutes.

  Hi Andy!  Mixamo services have not changed at all, so you can download characters customized to auto-rig yet.  Mixamo rigging and animation are all in a free preview, so you can use it to your heart's content.

  Fuse CC also still has the ability to import custom content, but you will need to create it with the Adobe fuse CC content creator package because the content for fuse CC is different from that of the content of fuse 1.3

  I can't understand it. When I write a script I do not get one commit even if in the result of the statement, it says "engaged." However with the same sql so I get out the commit and just execute the statement and then use the validation icon it works. For example, this will not sql commit
  
  delete

  Test_Table
  Where user_id = 'abc123 ';
  commit;
  
  But if I run it like this and click the validation for this:
  
  delete
  Of
  Test_Table
  When user_id = "abc123".
  
  Any info much frequented

  How do you run it? If you use F9 (or the green arrow), it runs only a single statement.
  If you use F5 (or the green arrow with a piece of paper behind it), it will run the entire worksheet (or the selected area) as a script.

  If both statements are running, you should see

  x deleted rows.
  Validation succeeded.

• I'm doing a blank publication widget, but he keeps ignoring my changes of State for relaxation. How can I have my state changes still work for the things placed in the trigger?

  So here's what I have so far. The menu works perfectly, thanks to some Youtube tutorials. And everything is connected properly. But the only thing is that the "WORK" button does not change of State which is set up for this. I tried to apply the change of State before I placed it in the trigger area and after. Doesn't seem to do the job.

  Objective status change is essentially the 'WORK' text will turn white and white space in the run will teal'c also turn teal'c. Thus, the colors will be reversed. I have a link next to it, "ABOUT", which is currently successfully. I suppose that if it is not possible then I'll have to find another design... but I would like to know if there is a way to do it!
