• How to run a function in the oracle plsql object when the object dies

  I have an object plsql function member as exec_last.
  I want this procedure that is called when the plsql object is cleaned or when the accommodation session this object dies.
  
  In C, we have a system call as atexit(). Is there such a feature in Oracle 10 g or no workaround using embedded java.
  
  This feature is required to empty the contents stored in the plsql in the object to the database, when the program terminates.
  
  Thank you

  Is there a better way to cache in memory.

  What is the Oracle buffer cache? It is exactly that - a cache for data blocks. The two new blocks (created by inserting new rows) and existing blocks (used by selects, updates and deletions and reused (freespace) inserts).

  The Oracle buffer cache is a cache of very mature and sophisticated. Trying to do "+ best +" to the db, buffer cache in another layer of software (such as PL/SQL) is mostly a waste of time and resources... and invariable introduced another layer of s/w which simply increases the number of moving parts. This in turn usually means increased complexity and slow performance.

  Why use the treatment in bulk from PL/SQL? The basic answer is to reduce switching between the PL and engine SQL context.

  During the execution of a code to insert data in SQL, the data must be passed to the SQL engine, PL PL engine must perform a context to the SQL engine switch so that it can process these data and execute the SQL statement.

  If there is a 1000 lines of inserts, this means that a 1000 context switches.

  In bulk treatment makes the "+ pipe communication / data + ' between the two biggest ones. Instead of passing data from one line to the SQL engine via a context switch, a collection of in bulk / picture of a 100 lines is passed. There are now only 10 changes of context necessary to push this 1000 lines of the PL engine to the SQL engine.

  You can do the same on any other client SQL... (remember, that the PL itself is also a SQL client). You can, using C/C++ for example, do exactly the same thing. When the row data to the SQL engine to insert, pass a collection of 100 rows instead of the data for a single line.

  The exact result of the same benefits as in PL/SQL. A pipe communication more, allowing more data to be transferred to and from the SQL, with engine for result less context switching.

  Of course, a context switch ito C/C++ is much more expensive than in PL/SQL - as the engine PL is located in the same physical process as the SQL engine. Using C/C++, this will usually be a separate process, to communicate with the SQL engine on the network process.

  The same applies to other languages, such as Java, c#, Delphi, Visual Basic, and so on.

  It not be wise to introduce another layer of s/w, the motor of PL/SQL and the customer "+ insert +" stored in his memory structures... and then use the PL engine to '+ flower' + for the SQL engine via a process control in bulk.

  It will be faster and more scalable, have the language of the client with treatment directly and dealing with the SQL engine directly in bulk.

  Simple example. What is SQL * Loader program (written in C), use? It uses no PL as a proxy to move data from a CSV file into a SQL table. He calls SQL directly. It uses a treatment in bulk. It is very fast to load data.

  There is an exception to this rule. What PL is used as a layer of processing and validation of business. Instead of the client code, implementation of this logic, it is done using LP. The customer then will not is more manually add an invoice to the table of the INVOICES for example. He called the procedure of PL/SQL AddNewInvoice instead - and this procedure does everything. It checks the valid client code. Ensures that there are stocks of the products ordered on the invoice. Etc.

  But in this scenario, PL is not used a flea market "buffer cache. It is used for what it was designed for - a correct application inside the database layer.

• How rate/knowledge so ready for the Oracle Certification

  Hi, I am interested in an Oracle Certification exam (1Z0-144), but I'm not sure if I'm ready.

  Any suggestions on how I could notice me if I am ready for the examination? I have (almost) no idea on what would be the review or what topics would be covered.

  Are there sample examination questions that might similiarly appear in the review?

  appreciate your answers.

  Oracle PL/SQL (and SQL) certifications are not really related to the output of the database as are the DBA certifications. The exam 1Z0-147 was developed during the version 9i, and the exam 1Z0-144 was developed during the release of 11 g.  However, a review wins the same certification credentials (i.e. you do not become a 'Oracle 11 g PL/SQL Developer Certified Associate'.  The reason is that SQL and PL/SQL undergo massive changes from one version to the other. However, they change slightly from one version to the other, and OU must periodically update information on trial so that it matches the available capacities.  I talk about this in the article below.  It is specific for reviews of databases SQL, but the basic concepts are the same for reviews of PL/SQL.

  Preparation of Oracle Certification: Oracle SQL Fundamentals exams and database versions

  Basically However - even if you are using oracle 10g, I recommend that you take 1Z0-144, because it's a review better than 1Z0 - 147.  I give my reasoning for it the following article:

  Oracle PL/SQL Developer Certification: 1Z0-147 or 1Z0-144?

• How to upgrade Windows XP to the video card of 2010

  I am told that I need the latest version of the drivers for video card 2010 game Gamehouse. How can I do this

  First you must determine which video card you have.

  If you have a computer 'brand', especially a laptop, it is best to get the drivers from the web site of the manufacturer of the computer.  Depending on the brand, you may need to enter a 'serial number (Dell) or type/model designation (Lenovo) and you should be able to get the video driver for your specific computer.

  If not, start the Device Manager (start > run > devmgmt.msc > OK) and click on the + sign to the left "display cards.  That should tell you the make and model of your video card.  You can then go to the web site of the manufacturer of the video card and download the current driver.  DO NOT select "Update driver" in Device Manager.  This will cause usually your download one driver Windows Update, which generally is NOT the current driver.

  There should be guidance on any web site, you get the driver from on how to install it.

• How to upgrade vcenter host when the host needs to be in maintenance mode

  Hi, I have a host 5.5 with 3 VMs (2 production servers and 1 Server vcenter). Now I see for updating the host using vcenter Update Manager documentation is quite simple. The thing I don't understand until you can fix, the esx host must be in maintenance mode, which means no VMs, including the vcenter server, which is the only way you can do a right click on the host and choose restore. Now how can I fix if the server is in maintenance mode and my vcenter server is down?

  I have the vsphere client installed on my laptop, version 5.5, but him, I did not have the remediation option. How can I put my 5.5 esxi host?

  Thank you

  With only one host in place and vCenter Server as a virtual machine running on this host, you cannot use Update Manager. Your options are either interactively update the host using a CD or update patch / the host from the command line using esxcli.

                              // this is where I want to replace the picture...
  
                              var data =  listComponentSearchResultsListItem.ListItem.view.dataModel.data(netscrape2.mListItemIndexPath);
                              console.log("netscrape2.data: " + data);
                              data.PreviewImage = netscrape2.adImageURL;
                              console.log("netscrape2.data2: " + data);
                              listComponentSearchResultsListItem.ListItem.view.dataModel.replace(0, data);
                          }
                      }
  
                  ]
              } // end of ListView
  

  Why all this way?

  listComponentSearchResultsListItem.ListItem.view.
  

  The above code is only necessary when you want to access the data of ItemComponent, but you try to change DataModel.

  You must change the value in your DataModel, in your case, its ID is searchDataModel. No what you have to do is something like this in your onComplete:

  var tmpData = searchDataModel.data(indexPath);
  tmpData.PreviewImage = netscrape2.adImageURL;
  searchDataModel.updateItem(indexPath, tmpData);
  

  Now I don't know what is ScrapeHttp, but it sounds like a weird way of this row.

  netscrape2.mListItemIndexPath
