• Export of database Session Bean (J2EE 1.4)

  Hello people,
  
  I try to implement a download of large files for end users, the data are extracted from a database.
  
  Configuration and Description of the problem:
  ----------------------------------------
  
  A J2EE 1.4 stateless Session Bean record-wise reads data from a large database table, generates a string of each record and adds the string in a text output for the download stream. The steps involved are (in pseudocode):
  
  For each record in the database table:
  1.) apply business logic to record data (formatting of numeric values, etc.)
  2.) Accumulate record data in a single string.
  3 writing string.) to an OutputStream
  
  When finished: download a file over HTTP to the end user.
  
  The processed data are very large (resulting text file will be 200-1500 MB), I think go with water courses is a feasible solution. An attempt at the interface of Bean Session would be:
  
  public OutputStream exportDb() {...}
  
  My problem is: inside the exportDb method, I implémenterai the algorithm described above, but this means that the whole issue will take place in the memory object (in the OutputStream). The download will be executed by a ServletOutputStream. How can I export the database table one recording by the other without implementing the logic of all its activities in a Servlet? The only way I can think is a variant of the Session Bean method that takes the ID of the record that must be treated as a parameter and executes the method in a loop in some servlet code:
  
  ....
  Somewhere in the Servlet
  OS = getServletOutputStream;
  
  for (int i = 1; i < nrOfRecords; ++ I) {}
  OS. Write (exportDb (i));
  }
  
  Is there else any solution "clean"?

  Assuming that you are working with a local ejb, you pass the OutputStream in the method, for example "exportDb (OutputStream out)" and move the outputstream servlet directly to the ejb. If you use a remote ejb, things get more complicated (I wrote a library for broadcasting remotely over rmi, called rmiio, that you can use if you are working with a remote ejb).

• Export of databases from phpMyAdmin on another server

  Tomorrow, I need to export 3 databases from one server to another using phpMyAdmin. I'm pretty confident, I can understand, but I want to be sure to leave a copy of the files on the original server. We know if there is an option that I choose to ensure that only one copy of the files are exported?

  I did several times without any problems.  Basic steps:

  1. Open PHPMyAdmin on the new server, and create a database exactly as your old server name.
  2. Open PHPMyAdmin on the old server, and then select the database you want to export, click Export.
  3. In the export window, make sure that all the tables you want to export are selected, SQL is the export and INSERT is the export type:

  

  1. Now click OK, a SQL script will now generate, copy and save this in a text file on your computer.
  2. So what you've done, it's creating an export SQL that maintains the original database intact.
  3. Select PHPMyAdmin on the new server and make sure you have the new database selected.
  4. Click SQL, paste the text and click OK, all your tables and the data should be inserted.
  5. If you have a localhost configuration on your computer, and then test this first.
  6. Don't forget to modify database connection files if the server host is different, or if you use a different database name, do not forget to change the name of it in the connection files as well.
  7. I hope this helps.

• Extraction of files from a time capsule that contains data of 3 different MacBooks. If I added a new macbook but I wanted only to select files. How can I find these files?

  If I have 3 different MacBooks stored on time capsule but I want only to add the files selected to a new macbook how I do it,

  find and retrieve files from these devices? How to retrieve the complete set of files for an individual device?

  If I wanted to get back anything, what is the process for this?

  Thank you

  Bill

  The correct method is to migrate. Use the migration assistant in the Utilities folder.

  However migrate doesn't have the fine selection you're after, if you do not want the entire folder like documents.

  You could find to manual aperture and copy the sparsebundle to Time Machine works ok... Use just traverse other disks of the main options of TM TM it in the dock.

  

  It might not allow you to recover files but I found that I could copy them into TM and then paste the files by jumping out to finder.

  Or you can migrate to another place is to say USB drive plugged into the computer and then retrieve files in a simple copy and paste... Although permissions can be a pain, and you must correct them before you can copy stuff to your own computer files.

• I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

  I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

  Yes, you can have a one word title, by assigning a paragraph style title to this one word. No, you cannot change the text in a Table of contents, but you can change paragraph style font attributes (line) and add for example, a head of points between the types of OCD paragraph and page numbers. No part of the table of contents will not provide hyperlinks in exported PDF documents.

  When you look up in the menu bar, you can see the word iPages, or simply Pages. There is no product of iPages.

• I have 3 radio button options to choose, but I want only a certain one for calculating sales tax. How can I assign a calculation to an option button?

  I have 3 radio button options to choose, but I want only a certain one for calculating sales tax. How can I assign a calculation to an option button?

  Ok. Let's say the name of the radio button group is "Radio1", the value of exports in this field is '3', the name of the subtotal is "Subtotal" and tax rate is 16%. You can use this code as the custom calculation of the tax field script:

  Event.Value = (this.getField("Radio1").valueAsString == "3")? Number (this.getField("Subtotal").valueAsString) * 0.16: 0;

• file not created when you use export to database

  I am creating a MAxL script to export the database but for some reason, the text file is empty (manual export works)
  
  Here is the script I use, any ideas on why it does not export the data
  
  set the error level.
  
  / * Connect to Essbase * /.
  
  Login "user1" 'password' on 'servername ';
  
  change the database for "Bud". "Budget" start archive file 'test ';
  
  database export "Bud". "Budget of all the data in the columns of data_file 'D:\\Hyperion\\essbase\\app\\Bud\\BUdtest1.txt '; »
  
  
  change the database for "Bud". "Budget of ' complete Archives;
  
  "exit";

  Not sure why you do the archives begin and end. When you perform an export, it locks the database. It could be the cause of your problems.

• Satellite A200-1hv - 4 GB of RAM but system see only 3.1 GB

  Hello

  I have the problem. recently, I bought 4 GB of RAM for my Satellite A200-1hv but system see only 3.1 GB.
  And yes I have tested also on 64-bit vista 64 and Linux 64 systems. In both cases, it shows only 3.1 GB.

  Also when I boot my laptop on the BIOS POST screen it test only 3.1 GB of RAM memory not 4 GB.
  The funny is that when I enter in the BIOS setup, and then in the main settings tab, it shows 4GB.

  Why?
  In the specification, it is written that this laptop supports 4 GB of RAM, but it is NOT!

  LMAN

  Have you tried to update the BIOS?
  Please do!

  Check if you are using the latest version, and if not then update the BIOS to the State.
