Writing data to a database

• Why the data in my database disappears when I restart Tomcat?

  I have a DPL Berkeley DB database that I use for a Web application that is running under Tomcat. I can store data in the database and get it back, but when I restart Tomcat and the data have gone. In my view, that the problem is that the data is in memory, it is never written to disk, so it is not persistent across reboots. I think that this, because when I write the data to the database, the size of the files in the data files does not change.
  
  My database is not transactional, nor in writeback mode.
  
  What else could cause this problem? I'm completely stumped.

  If the environment/store is not transactional (you do not call setTransactional (true)), then the data can be sustainable only equal to 1) you call Environment.sync, 2) a control point is executed by the thread of checkpointer I background or your application, 3) you close the environment itself, that will make a control point.

  I suspect that you do not close the environment when you shut down your server.

  You can take a look at the writing transactional Applications. He described the durability more in detail.

• faced with the question when writing data to a flat file with UTL_FILE.

  Hi gurus,
  
  We have a procedure that writes the data from the table to a flat file. RAC is implemented on this database.
  While writing data if the current instance, this procedure creates two copies of the data in parts.
  
  Any body can help me to solve this problem.
  
  Thanks in advance...

  I also asked this question, but it seems no final solution...

  In any case, here are two possibilities
  (1) the directory for the file among all nodes share
  (2) run you a procedure on a specific node

What would be the best way to go, and if they have advice on how to make would be welcome.

  Thank you!

  Hello!

  I would like to share with you that I found the solution to remove the mask before you update the database, I share case someone needs and evaluation of teachers is the best solution, I did the following creates a "process after Submit" before performing the "LMD" process, removing the masks as replace, just below my code is pretty simple as I said, my point in this case decided, as I have said I would like that assessment of you as possible to see if others have better enforcement solutions!

  : P33_NR_CEP: = replace (: P33_NR_CEP,'-', ");

  If I don't have permissions to create a database link. Is there another way to do this?

  Thank you.

  link to database IS the method by which an Oracle database accesses to a different database.

  If you are the ADMINISTRATOR, you should have permission.

  If you are not the ADMINISTRATOR, you should not have permission and need to talk to the ADMINISTRATOR that is allowed.

• Current version of the data in the database has changed since the user initiated the update process.

  Hello

  I get this error message: when I update a table.

  • Current version of the data in the database has changed since the user initiated the update process. version of current line identifier = "4975F66067C6EE412FF51DF46B8C4916" line application version identifier = "31163419BE48C198DE88A34AD12FE4D2".

  I get this message when a process is used to run an update on the same table.

  BEGIN

  RUN IMMEDIATELY "UPDATE CONTRATS_MAINTENANCE SET EMAIL_SENDED = 0 WHERE ID =: 1' WITH THE HELP OF: P27_ID;"

  END;

  There is an automated line (DML) process process on the table on this page.

  
  

  I understand that I get this error message because I update the database EMAIL_SENDED in the same table column and tha the automated process line try to update the same table...

  On this page, I want to the column EMAIL_SENDED always has the value 0 (zero). It is a database column

  How to do?

  Thank you for your help.

  Christian

  If you try to make it through a normal form. So in this case email_sended is getting two values one of your FORM and one of your update statement.

  To resolve this problem, you can code in hard EMAIL_SENDED point the value '0' and keep only the database column.

  If the whenver update you will automatically take the value 0.

  Another solution would be to remove this column from your FORM and then update by creating a process after submit.

• How to keep summers jsf pages correctly updated to account for changes to data in the database?

  This is a case of common use for web applications:

  User open A (i.e. a jsf page) of a web application, keep open for a period of time and do some browsing or editing on this page.

  During this time, someone others or modified events of the data in the database, then:

  Scenario A:

  1. the user should be able to see the evolution of the data in the above open jsf page when page navigate to other records.

  or when the page is refreshed by refreshing the web browser (reload the page) or by pressing a button on the page manually.

  Scenario b:

  2. the page should be able to be updated automatically to reflect the new changed data in the backend database.

  -This means that the user has no need to run the refresh action intentionly/manually to get the new data.

  Here's a possible implementation are provided in subsection 12.1 JDEV/ADF for above use cases:

  1.kdario: tips to know how to refresh your data

  Re: Field Image cannot refresh when you move between records in a jsf page

  In my opinion, the solution of kdario is a little bit complicated, is there an easy approach?

  and kdario says:

  'normal way' for update page is generally very bad for applications based on JSF/ADF.

  Is there more evidence or reference documents to support above sayings?

  2 to implement scenario B, which is recommended methods?

  Is the Active Data one approach good?

  If there are active - as tech batteries was adopted for web applications on the internet (which will have more agreement than in the intranet user), would there be possible serious performance problems?

  Thanks in advance.

  In fact, I suggested to the position 3 solutions (and option c) Notifications of changes to database is the most complicated).

  Also, here is solution d) in pageDef, select iterator and ownership of Cache set to false results

  'normal way' for update page is generally very bad for applications based on JSF/ADF.

  Is there more evidence or reference documents to support above sayings?

  Well, when you use the "back/refresh" browser button, this will retrieve the Forms page cache and skip the controller of the ADF.

  You can use google to do this, for example:

• retrieve a row of data from mysql database

  Hello

  I extract data from a database.  Use of then in a Web page as <? php echo $row ['product'];? >

  However, if there is an apostrophe in 'product', he displays like a diamond with a question mark.

  Data stored in the database looks like this, 'pearls of Mary. "
  

  Is the problem when I have the data stored in the database or when it was recovered?

  Thanks, Dan

  This happens usually if you paste from another application like Word or Xpress directly in the database.

  To work around the problem:

  If you are still using the old mysql extension insert the line below before any other query mysql on your page:

  mysql_query("SET NAMES UTF8");

  If you uisng the new mysqli extension then use the variable of connection string (in this case $conn) as below:

  $conn-> query ("SET NAMES UTF8");

• Current version of the data in the database has changed since the user has launched the process of update: tabular

  Hi people

  Version of the apex is 4.2

  Oracle database: 11.2.0.2

  I have created a simple form in a table on a table with the following structure

  I wanted to add an additional line inserted in the tabular presentation, that's why I included 'UNION ALL' in the query like this

  Union of all the

  created_dt null,

  created_by null

  After having done that, I can see a blank line on the form of tables, but each time I fill data in the fields and press the "SUBMIT" button, I get the below error

  Why are you insert an extra line manually in tabular from?  There is a feature to add a line.

  If you want to insert a blank line when the page loads, then create dynamic action, this is a most appropriate feature.

  If you manually insert an extra line so that you have to write the update for this procedure.

  Leave.

  Hi Maury,

  There is no need in step 2 that u mentioned above. I donot find useless a webservice?

  The process will be launched by the CSV file, then using the processing activity, you can put it in the DB.

  There should be no way where you can manually test it by giving an entry. All you can do to test is to put the file in the folder you mentioned when configuring the file adapter.

  You just need to have the composite as below:

  ReadCSVFile---> BPEL--> DB adapter

  And in your BPEL process:

  Recieve--> Transformation activity--> call activity

  Try to work on some samples listed on the oracle site and go through the below URL:
