• 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

  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

• 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

• Using the database link to connect to two databases

  Hi guys,.
  Here's my question. I need to give to a Select rights contractor on the tables located in two schemas located on two different servers. A dev server and a prod. Let's say we have a user schema: EMPLOYEE on the dev and user schema: DEPARTMENT on prod. The outside contractor needs certain rights on all the tables in the schema DEPARTMENT but just select on a few (4 to be exact) tables from a diagram of the EMPLOYEE.
  
  My first train of thougth is: CREATE a named user: TEST (of course, only used for an example of random name) for contractor on prod. Give some rights to TEST user on all the tables in the schema of DEPARTMENT.
  Create the link of database to the dev server so user TEST can access the EMPLOYEE schema.
  
  How can I go to limit the user TEST link database to display only 4 tables to EMPLOYEE instead of all the tables?
  
  Should I also do this scenario backwards? Creating user TEST on dev, giving rights TEST for 4 tables in the FRAMEWORK, and then creating the database for you link connect to schema Department on production database?
  
  Any help will be appreciated. Thanks in advance.

  Just set up a new DEV scheme to be used by the link of database connection string.

  -create synonyms in this schema@DEV for these four tables.
  -grant select access on these four tables to this schema@DEV.

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

  Hello

  I am a beginner in the creation of Mobile-based Web sites. So, please can someone help me as I want to use a database for a website of the mobile base. How can I proceed further on this issue? I know what database I use and how a connection can be made to it and using what language?

  Please do not respond.

  Thank you and best regards,

  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.

• ONLY INSERT OR DELETE THE PRIVILEGE TO THE DATABASE LINK

  Hi all

  Version of DB 11.2.0.1

  RedHat 5.5 operating system

  I created a link to private database by following the path

  create database link test_link

  connect to Scott identified by tiger

  using

  '(DESCRIPTION =)

  (ADDRESS = (PROTOCOL = TCP) (HOST = 10.194.180.45)(PORT = 1521))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = prod)

  )

  )'

  The link is created successfully and I am able to perform all the DML operations on it.

  The Question is there a way by which we can give only insert or delete or privilege is not to remove from the table at this link.

  For operations select only, I know that by creating a view I can restrict the remote user, but is there a way by which I can give only insert or remove remove link of database.

  You can not grant any privilege to a link. Can you and your team identify a location in the documentation, if required?

  By default, a remote session will get the same privilege as the user to which it connects.

  BTW:

  • do not use a database link tnsnames.ora makes your hard to maintain link
  • using addresses IP hard in a database link makes your link even more difficult to maintain
  • by specifying a hardcoded password in a database link is a breach of security.

• try to reduce the database links

  Hello. Thank you for helping.
  
  
  I think my basic question is this:
  
  
  I can connect and create database links that can be used by all other users (and tablespaces?) on the server?
  
  
  I have a bad understanding of how the areas of storage, dblinks and users go together, so I'll briefly describe my setup process so you can see how I have things that can be part of the cause of my confusion, possibly in a subtle way.
  
  
  For this example, I have 2 servers with Oracle 11 g Enterprise.
  
  
  After you create a database, I then create tablespaces, users and links like this:
  
  
  On server 1:
  
  
  create storage my_app1
  create the user my_app1
  create storage my_app2
  create the user my_app2
  
  
  and so on for all areas of storage and users on the server.
  
  
  Then log in as my_app1 and create a link of database on server2:
  
  
  link_to_s2 fixed my_app3 user
  
  
  Then log in as my_app2 and create a link of database on server2:
  
  
  link_to_s2 fixed my_app3 user
  
  
  Same process on server2:
  
  
  create storage my_app3
  create the user my_app3
  create storage my_app4
  create the user my_app4
  
  
  and so on to server2.
  
  
  Then log in as my_app3 and create a database link to server1:
  
  
  link_to_s1 fixed my_app1 user
  
  
  Then log in as my_app4 and create a database link to server1:
  
  
  link_to_s1 fixed my_app1 user
  
  
  It operates well for me, except that I have to create four dblinks.
  
  
  Is everything I see how this can be simplified to create dblinks less?
  
  
  Any suggestions are greatly appreciated.

  Hello..

  Why not create a public database link.

  Documents: -.

  Specify the PUBLIC to create a public database link available to all users. If you omit this clause, the database link is private and is only available to you.

• Authentication of database through the database link

  Is it posible to use database authentication in the APEX by link of database and how?

  Also is it posible to reading user roles through the database link?

  Database links to establish the connection, so you lose the context regarding which is recorded in a single user.

  Custom authentication can do some PL/SQL you need, but I would say that replicate your tables locally through something as materialized views.

  You could also potentially be used dba_role_privs, but do not forget roles can be turned on/off.

• SpeedGrade CC14 does not open when you use the "Direct Link to Adobe SpeedGrade... "of PremierePro CC14.

  SpeedGrade CC14 does not open when you use the "Direct Link to Adobe SpeedGrade... "of PremierePro CC14.

  I can open the SG of start menu/desktop computer and I can open the PP project in SG very well. The PP project contains 3 deadlines and I take one I want without any problem. Returning to the SG PP works fine as well. It seems only thing doesn't work does not automatically open the PP file and selecting the correct timeline in the Official Journal of the project.

  I had a glance at the "C:\Users\john Bishop images\AppData\Roaming\Adobe\SpeedGrade\8.0\logs\SpeedGrade.log ' but it is not updated when I try to use the link Direct from PP. command It updated when I invoke the start menu/desktop computer SG. Note that none of the other newspaper, the files are updated either (Plugin Loading.log, Database.txt Trace and Debug Database.txt). All these get updated when I run the desktop/start. It would appear that SG is not yet known.

  I uninstalled the SG and the PP and re-installed (all in the directories by default) and everything seemed to go OK but no change.

  I also added 2 political profile the NVIDIA Control Panel, just display a message when loading SpeedGrade.exe and another for a slightly different message when loading SpeedGradeCmd.exe. SG invoking the desktop/start causes the SpeedGrade.exe message to display. Using the 'Direct link' PP file option does not display anything, reinforcing my thought that SG is just never called from PP.

• strange problem with the database link

  Hello world
  
  I have a strange problem with the link of database in Oracle 11 g Express Edition;
  There are two computers: computer-server and the client computer. Tnsnames.ora are the same on both computers IE.
  
  CT =
  (DESCRIPTION =
  (ADDRESS_LIST =
  (ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof) (PORT = 1521))
  )
  (CONNECT_DATA = (SERVICE_NAME = XE)
  )
  )
  
  I created the database link:
  
  Create database link zdalny
  Connect to < user_id > identified by < password >
  using "CT".
  
  Customer cannot connect with server when I do not use above the command. But when I change 'use' for using "krzysztof:1521" or by using "krzysztof" or "server IP:1521" - everything is ok.
  
  Why I ask. Because in all the materials that I read about Oracle command with the help of "CT" should work correct. But there is no. Do you know why?
  
  Thanks in advance and apologize me for my English.

  Here's the tnsnames of your server, but to connect to the oracle server db (any client or to another instance of db oracle), you must install oracle client.
  However, in your condition, you want to connect the DB1 Oracle OracleDB2 using a link db, I'm right? In this case you should always set the entry in the tnsnames.ora
  To verify that you can connect to Oracle DB2 from DB1 Oracle, you can use tnsping in the command line.
  In your case

  c:\tnsping CT

  )

  Check your tnsnames entry in the machine, you are trying to connect to. And check if the tnsping is successful.
  Sometimes the error message says not everything, which means that you need to troubleshoot yourself and learn from the experience.
  Always in the opposite case, refer to the documentation.

  See you soon.
