  Thank you
  Any help appreciated.

  This message indicates that Oracle wants to re-use a redo log file, but
  the
  associated with corresponding control point is not over. In this case,.
  Oracle
  Wait for the control point is carried out entirely. This situation
  may be encountered especially when transactional activity is
  important.

  search for:
  -Background checkpoint started.
  -Control your mat point.

  These two statistics should not differ more than once. If it is

  not true, your base weighs on the control points. LGWR does not reach
  continue
  next write operations that ends the control points.

  Three reasons may explain this difference:

  -A frequency of control points which is too high.
  -A control points are starting but not filling not
  -One DBWR writing too slowly.

  How to resolve incomplete control points is through tuning
  control points and
  newspapers:

  (1) gives the checkpoint process more time to scroll through newspapers
  -Add more redo log groups
  -increase the size of the logs again
  (2) to reduce the frequency of control points
  -increase the LOG_CHECKPOINT_INTERVAL
  -increase the size of newspapers in restoration online
  (3) improve the effectiveness of the control points for the CKPT process
  CHECKPOINT_PROCESS = TRUE
  (4) set LOG_CHECKPOINT_TIMEOUT = 0. This disables the verification script
  based on
  time interval.
  (5) another way to solve this error is for DBWR to write quickly
  the dirty
  buffers to disk. The parameter associated with this task is:

  DB_BLOCK_CHECKPOINT_BATCH.

  DB_BLOCK_CHECKPOINT_BATCH specifies the number of blocks that are
  dedicated
  inside the batch size for writing the control points. When you want to
  speed up
  control points, it is necessary to increase this value.

• How to set permissions for drives avoid the ORA-15063 start-up ASM?

  Hello

  When I try to reboot the DSO after a reboot of the server, I get

  ERROR: diskgroup DATA was not mounted

  ORA-15032: not all changes made

  ORA-15017: diskgroup 'DATA' cannot be mounted

  ORA-15063: ASM discovered an insufficient number of drives for diskgroup "DATA".

  It seems the permission of disks have changed after the reboot. I guess the spfile is inside the DATA diskgroup because it can not even start ASM. When I create a file with values asm_diskgroup and asm_diskstring pfile and 777 on the drive, I managed to start the ASM.

  * .asm_diskgroups = "INDX", "DATA".

  * .asm_diskstring = "/ dev / *'"

  $ oracleasm querydisk p - DATA

  Disk 'DATA' is a valid ASM disk

  / dev/sdb4: LABEL = 'DATA' TYPE = 'oracleasm.

  $ ls-la/dev/sdb *.

  ...

  BRW - rw - 1 root disk 8, 19, 29 mai 10:42 / dev/sdb3 it

  brwxrwxrwx 1 root disk 8, 20, 29 mai 15:17 / dev/sdb4

  ...

  And when I read the documentation I see this ' that the owner of the ORACLE binary file has permissions to read/write on the discs"(so do not run required) but the problem is that this test server should have the same parameters as in production. And the production server has brw - r - for the corresponding disk. So my questions are

  Can it be handled somehow in a different way? How can this have been reached production without the same settings I put in test? Is there an other way around for me in test to achieve?

  The network user (who owns the infrastructue grid) belongs to the same group of test and production. Test and production have ASM version 11.2.0.3, but the different operating system.

  production: 2.6.18 - 274.12.1.el5

  test: 2.6.32 - 504.16.2.el6.x86_64

  As this is my first ASM/grid infrastructure, I don't even know where to begin this review except the support.oracle.com search but I've not found anything except the Action for the error code (which is perhaps the only way around it)

  Any help is appreciated

  Thank you

  / Jenny

  Remember that the permissions of the device must be configured so that the owner of the Oracle database or the process has full access to the appropriate device files. It is not enough to only give ASM full authorization for devices files. ASM provides management for volume, but the database has direct access to device files and ASM does not interfere with inputs and outputs. You can set up groups and owner accordingly. If you have a different owner for ASM, you must assign appropriate groups to give full access ASM configuring oracleasm.

• Avoiding the TRUNC as a condition of setting for the date of transaction

  I've never noticed this before, but tonight I have tested a query and made a trunc (mmt.transaction_date) between April 1, 2012"and 20 April 2012 ' in TOAD and I noticed it was taking a long time to run.
  
  If I remove the trunk and use mmt.transaction_date > = 1 April 2012 ' and mmt.transaction_date < 21 April 2012 "the query ran a lot faster and the explain command plan was also much better."
  
  Then I read that this truncing the date of the operation will be used the index on this field in the table when searching it.
  
  But if I change the setting so that the condition is set to add - it to the parameter, it does not work and maybe someone can help you. This is probably an obvious solution that I just think not.
  
  I created the discoverer as conditions:
  The operation date > =: Start Date of Transaction
  and
  The operation date < = (: Start Date of Transaction + 1).
  
  But I get an error "one of the arguments of the function has an invalid data type.
  
  Or maybe I'm wasting my time trying to avoid using the TRUNK on the date of the transaction?
  
  Kind regards

  You should be OK with the condition:

• Using bulk collect into with assistance from the limit to avoid the TEMP tablespace error run out?

  Hi all

  I want to know if using bulk collect into limit will help to avoid the TEMP tablespace error run out.

  We use Oracle 11 g R1.

  I am assigned to a task of creating journal facilitated for all tables in a query of the APEX.

  I create procedures to execute some sql statements to create a DEC (Create table select), and then fires on these tables.

  We have about three tables with more than 26 million records.

  It seems very well running until we reached a table with more than 15 million record, we got an error says that Miss tablespace TEMP.

  I googled on this topic and retrieve the tips:

  Use NO LOG

  Parallel use

  BULK COLLECT INTO limited

  However, the questions for those above usually short-term memory rather than running out of TEMPORARY tablespace.

  I'm just a junior developer and does not have dealed with table more than 10 million documents at a time like this before.

  The database support is outsourced. If we try to keep it as minimal contact with the DBA as possible. My Manager asked me to find a solution without asking the administrator to extend the TEMP tablespace.

  I wrote a few BULK COLLECT INTO to insert about 300,000 like once on the development environment. It seems.

  But the code works only against a 000 4000 table of records. I am trying to add more data into the Test table, but yet again, we lack the tablespace on DEV (this time, it's a step a TEMP data)

  I'll give it a go against the table of 26 million records on the Production of this weekend. I just want to know if it is worth trying.

  Thanks for reading this.

  I really need check that you did not have the sizes of huge line (like several K by rank), they are not too bad at all, which is good!

  A good rule of thumb to maximize the amount of limit clause, is to see how much memory you can afford to consume in the PGA (to avoid the number of calls to the extraction and forall section and therefore the context switches) and adjust the limit to be as close to that amount as possible.

  Use the routines below to check at what threshold value would be better suited for your system because it depends on your memory allocation and CPU consumption.  Flexibility, based on your limits of PGA, as lines of length vary, but this method will get a good order of magnitude.

  CREATE OR REPLACE PROCEDURE show_pga_memory (context_in IN VARCHAR2 DEFAULT NULL)

  IS

  l_memory NUMBER;

  BEGIN

  SELECT st. VALUE

  IN l_memory

  SYS.v_$ session se, SYS.v_$ sesstat st, SYS.v_$ statname nm

  WHERE se.audsid = USERENV ('SESSIONID')

  AND st.statistic # nm.statistic = #.

  AND themselves. SID = st. SID

  AND nm.NAME = 'pga session in memory. "

  Dbms_output.put_line (CASE

  WHEN context_in IS NULL

  THEN NULL

  ELSE context_in | ' - '

  END

  || 'Used in the session PGA memory ='

  || To_char (l_memory)

  );

  END show_pga_memory;

  DECLARE

  PROCEDURE fetch_all_rows (limit_in IN PLS_INTEGER)

  IS

  CURSOR source_cur

  IS

  SELECT *.

  FROM YOUR_TABLE;

  TYPE source_aat IS TABLE OF source_cur % ROWTYPE

  INDEX BY PLS_INTEGER;

  l_source source_aat;

  l_start PLS_INTEGER;

  l_end PLS_INTEGER;

  BEGIN

  DBMS_SESSION.free_unused_user_memory;

  show_pga_memory (limit_in |) "- BEFORE"); "."

  Thanks in advance for your suggestions.

  Hello

  So when deptlocation is in the two tables, but not the same thing, you want to take the value of the table emp, not the dept table.

  In this case, reverse the NVL arguments:

  WITH     got_rnk          AS
  (
       SELECT     deptno, deptname, deptlocation
       ,     DENSE_RANK () OVER ( PARTITION BY  deptno
                                 ORDER BY          NVL2 ( deptlocation
                                                , 1
                                     , 2
                                     )
                         )     AS rnk
       FROM    dept
  )
  SELECT     e.empno
  ,     e.empname
  ,     e.salary
  ,     r.deptno
  ,     r.deptname
  ,     NVL ( e.deptlocation          -- Changed
           , r.deptlocation          -- Changed
           )          AS deptlocation
  FROM     emp      e
  JOIN     got_rnk     r     ON     e.dept     = r.deptno
  WHERE     r.rnk     = 1
  ;
  

  Apart from the 2 marked lines "Changed", it's the same query I posted earlier.

• How to avoid the duplicateConnection on a sql database?

  I have a database of newspapers that I have access to both c ++ and QML.

  While everything works correctly logs qml page complained about a double connection whenever it is open, which in turn spam log file.

  In c ++, the database is initialized once, with db being QSqlDatabase:

  QString databaseFileName = QDir::homePath() + QDir::separator() + "logs.db";
  db = QSqlDatabase::addDatabase("QSQLITE", "loggerDatabase");if (!db.open()) {        printf("Critical: Error opening logs database\n");}
  

  QML, I use a very simple way to view the contents of the db: A GroupDataModel with a data source.

  I have set up a query on the data source and fill in the datamodel with the result:

  DataSource {
     id: dataSource
     source: loggerService.dbPath
     onDataLoaded: {
        dataModel.clear();
        dataModel.insertList(data);
     }
  }
  

  I assume that the data source uses SQLDataAccess to open a connection to the db, and db already has a connection there is a complaint:

  QSqlDatabasePrivate::addDatabase: duplicate connection name ' / accounts/1000/appdata/x/data/logs.db' old deleted connection.

  How can I avoid this?

  I've given up trying through QML and just dynamically added the groupDataModel of c ++.

  I was getting the same error, without reason.

  Hey, Malcolm.

  Best way to explain what basically rendering 3D correctly really takes a lot of time, haha.  So that you may be able to work with the real-time 3D model and make changes quickly, we use two different rendering methods.

  There is an "Interactive" mode which is not like the beautiful light/shade, but is very fast - and that's what you see when you interact with the default template.

  Then, there is a mode "Raytraced" which is much more advanced calculations and stuff to give you a proper lighting / shadow.  Raytraced rendered may take time if so we can not use it all the time.

  In order to get the lights/shadows appropriate you need to perform a path Ray would make on the document.  Best way to do this:

  • Select your 3D layer in the layers panel
  • Make a selection in the drawing area to the area that you want to make (I recommend to test rendering of area to check the lighting/shadows before committing to make the whole layer).
  • Push the button is rendered at the bottom of the properties panel (it looks like a cube in a rectangle box, right next to the delete icon).

  There are other things that you must do if you want to get the best image search quality such as the addition of secondary lights!  You can add more lights in the 3D Panel using the small icon of light at the bottom.  Have 2-3 stage lights and adjusting their colors can make a big difference with the Assembly of your character in the scene.  Here is a small image for some comparisons:

  

  You can see the image with two lights a look much more realistic lighting and shadows and raytraced of one and two versions are much nicer and cleaner!

  Hope that helps!

• How to avoid the OutOfMemory exception in an intensive application of memory in Java?

  down to the voice favorite

  We have developed a java application, whose goal is to read a file (input file), treat it and convert it into set of output files. (I gave a generic description of our solution, to avoid irrelevant details). This program works perfectly well when the input file is 4 GB, with memory settings-Xms4096m-Xmx16384m in a 32 GB of RAM Now we need run our application with the input of size 130 GB file. We used a linux machine with 250 GB of RAM and memory setting of - Xms40g-Xmx200g (also tried a few other variants) to run the application and click on OutOfMemory Exception. At this stage of our project, it is very difficult to think about the redesign of the code to meet hadoop (or someother large-scale data treatment framework), the current hardware configuration which we can afford is also 250GB of RAM. Can you please offer us ways to avoid the OutOfMemory Exceptions, what the general practice when developing applications of this kind. ? Thanks in advance

  Thanks a lot for all your quick responses.

  We decided to investigate the Redis it will solve the problem that is described in the post. All hashmaps can be put in databases (secondary memory) and exceptions of memory can be managed.

• How to avoid the FDM-command being moved files from the OpenBatch folder

  Hello world
  
  I have a little problem with Batch Processing of the FDM - I need to stop the movement of files in the folder OpenBatch - when a batch is executed.
  
  The installer by using the Task Manager, a load a Batch Script and Script integration all works very well. However, the process must run every 3 hours, so I need the file "A_LedgerTransLocation_Actual_nov - 2013_RR.txt" to remain in the \Inbox\Batches\OpenBatch\ folder at any time.
  
  How to avoid the file is moved?
  
  
  Best regards
  Frederik
  
  
  
  
  PS: I noticed on the OTN Forum is it may be possible to script a solution such as:
  
  FSO1 = CreateObject ("Scripting.FileSystemObject") set
  Set File1 = FSO1. GetFile ("FDM Directory\FDM Application\Inbox\Batches\Openbatch\A_LedgerTransLocation_Actual_nov-2013_RR.txt")
  The BATCHENG value. PcolFiles = BATCHENG.fFileCollectionCreate (CStr (strDelimiter), File1)
  
  However this is not possible, as the controllers of the company need to edit the. TXT file themselves. They will not be able to edit the script too.

  I don't think you can prevent the FDM, move the file. I'm assuming that the file change in each period to use the last period of POV, so I think that option easiset to copy the file (based on a part of the name (location?) to a temporary location before began the FOM and write again later.)

• best way to avoid the full table scan for clause "column is zero.

  I have a query with is control null, and because of that it performs a total scan of table (in millions of rows in the table)

  What is the best way for me to avoid the full table scan. I have indexes for the X column and other columns.
  
  Thank you

  Hi Vasif

  NULL values are indexed if the indexed entry also includes a value non-zero.

  If you create an index such as:

  CREATE INDEX mytable_x_idx ON mytable (x, ' ');

  ensure all null values for the column X are indexed and will therefore potentially use the index to search for null values, assuming of course the result set is small enough to justify the use of the index in your query.

  I have spoken previously on my blog:
