• How s/n know when and what account perform a function using the database link?

  Dear,

  My application of the CIM team asked DBA to create new function and run it. Function must use the database link for remote database data. So I need to create a new database to their licensing link. Cause we guess we'll experience the performance issue after the user performs this function, or another question and errors may occur. So we want to know when and who use this feature that connects to a remote database through the new database connection in advance. And I also need to know when and which connect to the remote database using this new database link. We have no idea to get this information?  Can anyone recommend how do? Thank you very much.

  Best reqards, Otis.

  Check what business purpose, it will solve.  If the function is so safe, why everyone will use. Only admin people should access.

  All of these additional controls of this kind must be avoided as much as possible to improve the overall performance of the application.

  Still if you need, see the database audit mechanism, specifically designed for this type of activity.

  Kind regards

  Dear all,
  
  I am new to Oracle GoldenGate...
  
  How to use the database connection in GG?

  Amina,

  You have two choices. First choice, that's what you do, but your syntax is off. It should be:

  REPLICAT load6
  Sh@docqvoice_db username, PASSWORD sh
  ASSUMETARGETDEFS
  CARD sh.products, sh.products of the TARGET.

  Second choice is to create a view on the source using the link from the target database and map display just as in:

  REPLICAT load6
  Username, PASSWORD sh
  ASSUMETARGETDEFS
  CARD sh.products, sh.view_on_products of the TARGET.

  Good luck

• What I need to import the database - impdp.

  Hello
  I question as what I need if I want to create the database form DMP fiir copy made by expdp full = y.
  Now I want to cretae this database by impdp full = y BUT I have an other paths (Windows system).
  Once a week I can finally cretae instance, instance of startup and now I struggle with this oracle 'user friendlY' to create the database.
  But what I need to import the database by impdp? I think that I need software Oracle - installed instance (oradim) and after (startup nomount) and what next cretae database? and adter import DMP file form?
  How can I create thid BD if I want the same, as it is in the dmp file?
  
  Thanks for the replies.

  Hi all

  As the paths are different and you did export using utility datapump

  During the import, you want your data files on different paths...

  Thus, you should use Remap_datafile for sure and (if necessary) Remap_tablespace

  Give a list of the sql operators, who use the database indexes.
  
  I'm interested to know if ' group by '-operator uses indexes.

  why it has not been used here?

  because there is no general rule to that: as stated it depends on table and index layout if the optimizer decides to go to index or not.

• I want to use the database to 10g control

  Hello
  
  I installed oracle 10g on Windows client. He installed Oracle Enterprise Management Console.
  
  I created all of my databases by using create database on a UNIX server instructions.
  
  Now, I want to use the database to monitor these databases. How can I do this? I don't see a link or the icon of the database command console.
  
  Thank you

  How did you do that?

  If you talk about the control of database (http), once to create the DB control repository (which should be on the UNIX server), and then use the URL and the Port number that you learned at the end of the installation to access it from the Windows machine. This should be in the format:

  http://yourunixservername:port / em

  for example

  http://dbmsdirect01:1158 / em

  or

  https://dbmsdirect01:1158 / em

• Reading large data using the database connectivity

  Hello

  I use the Labview database connectivity toolkit to connect to my database sqlitev3 (I'm using ODBC). I just have to connect to the database (using the block of open_connection) and read all the values inside (using the select_data block). The problem is that my database is huge (about 2 GB), and I get this error:

  What should I do? It seems that he reads the data in the memory and it doesn't have enough space for it. When I read the data I want to write to a file.

  

  Read it in pieces. Write each piece to the file, and then repeat with the next segment. Try to read and process all data in one shot is not very practical and you found out will not work.

• How to create and use the database in the development of a mobile Web site?

  If you are a Microsoft Developer, you can use ADO.NET to access the database.  This is because it is the technology on the server side and is running on the web server and not to the device.

  You can create your Web site by using one of the web technologies side server such as ASP.NET, JSP, PHP etc. Any technology that will serve up to HTML will work.

  When developing web sites for mobile devices, you will quickly realize that it is not a "one size fits all".  Each set of HTML markup will probably have to be customized for each of the mobile that you are eager to target.  And then, for each version of the operating system for mobile devices there are differences in sizes of rendering, JavaScript and HTML/CSS screen capabilities.

  My best analogy is thinking differences between desktop browsers such as IE5/6/7/8, Firefox, Chrome, Opera, Safari vX.Y.  Then multiply that by about 10 fold when it comes to differences in mobile browsers.

  Have a Web site that supports all mobile devices with a set of means HTML you'll probably adopt an approach more common denominator based on lowest mobile device features, you want to support.  The alternative is create targeted for each mobile user experiences.

• Using the database links in a process of page plsql

  I try to use a database link in a process of pl/sql page.
  

  It works fine when I use the link name in the plsql like this:

  BEGIN 
  SELECT  
  CARD_ID 
  into   
   :P12_HDR_CARD_NUMBER  
  from     [email protected]; 
  

  But the name of the link will come an element of page (P12_DBLINK) filled as follows:

  select db_link d, db_link r from user_db_links;  
  

  I tried the following and it doesn't work:
  

  DECLARE 
  l_link VARCHAR2(30); 
  BEGIN 
  l_link :=  :P12_DBLINK; 
  SELECT  
  CARD_ID 
  into   
   :P12_HDR_CARD_NUMBER  
  from     fusion.EXM_CC_COMPANY_ACCOUNTS@l_link; 
  

  It gives me:
  

  • ORA-04052: error occurred when searching to the top of the remote object MERGER. EXM_CC_COMPANY_ACCOUNTS@L_LINK. WORLD ORA-00604: error occurred at recursive SQL level 3 ORA-02019: description of the connection to the remote database not found

  I thought that perhaps the name of the link was joined with. WORLD automatically but already has the name of the link. WORLD at the end I tried stripping first but the error is the same.

  Is there some synatx for what will work? Can I use dynamic sql statements?
  

  Any suggestions are most appreciated.

  Thank you

• How to determine the user who uses the database object

  Hello
  Currently, we are consolidating our databases. One of the steps is to understand that the user connects to the database at all. It's easy, we have implemented a logon trigger and save the information in a separate table.
  If a user with objects (tables, views, procedures) are - but that this user never connects to the database - which automatically means that these objects are not at all? Needless to say that's not true. But how do know us if a user has selected an object to this user?
  Our problem is that we have a lot of patterns in our database-, but the developers do not know if this schema is not used by an application or not (sad but true).
  To enable the audit would be a choice about whether or not an object is already used.
  Are there other possibilities?
  Any help would be appricated

  It could be even easier by turning on auditing functionality.

  verification would be a good choice.

  Don't know this that developer will be used/not used with the application.

  To enable the audit would be a choice about whether or not an object is already used.

  What is the problem in the audit?
  Even if the audit may have a footprint on the performance, which would be probably cheaper than any customized solution.
