• Drop the link of database in oracle 11g

  I created a schema with the name of sapsmc which has all the privileges, then I created 1 link of database. Now, I want to drop this database link, but I can't able to drop this error.

  «SQL error: ORA-00604: error occurred at recursive SQL level 1 ORA-20101: Sorry, can't remove any object without the permission of live database SAPGateWay.» ORA-06512: at the level of the 5 00604 line. 00000 - 'error occurred at recursive SQL level %s' * Cause: an error occurred during the processing of a recursive SQL statement (a statement applicable to the internal dictionary tables). * Action: If the situation described in the next error on the stack can be corrected, do so; otherwise contact Oracle Support.

  Then I tried to delete the user SYS, while doing this that I got below error.

  SQL error: ORA-02024: database not found link 02024. 00000 - "database link not found" * Cause: database to remove link is not found in the dictionary * Action: correct the name of the database link

  Please help me I appreciate your efforts.

  ORA-20101: Sorry, can't remove any object without the permission of live database SAPGateWay.

  There is not much we can do about it.

  It is an exception defined by the user, probably from a FRONT DROP trigger defined at the level of the database, which prevents people from dropping objects.

  Contact, one who is responsible (DBA?) about how to proceed.

• Oracle database can interact with sysbase database in real time?

  There are two database, it is oracle, one is sysbase, sysbase is the database of products. My program only can consult the oracle database and cannot visit sysbase database directly. My question is whether there is a direct connection to oracle, sysbase herbal database, when I visit oracle, oracle database can interact with sysbase database through this link in real time? How to make above function? Please give plan for her.

  Yes it is. You must create a heterogeneous connection between these two databases

  Be sure to distinguish between the terms and the database schema. Other products, make them bad. It would be a HR diagram (or a user, which is the same in Oracle). If you do not need to use the database Wizard, unless you are working with a new host with no database.

  A simple way would be to get the DDL to create the HR schema and modify it for your own. It can be extracted from your database in several ways, or you can copy the hr_cre.sql to your own script and change. The two ways are educational, and you can google for instructions.

  Please I really need your help I really really need this to work and I'm completely lost know.

  I look forward to hearing from you soon.

  Vinny.

  Hey Vinny,

  No, the host tnsnames.ora must not refer to the place where the SQL * Server database is active.  The tnsnames.ora entries is intended to guide the user who calls the database link by using this entry to a listener running on the computer and the port in the entry. The listener then directs the user to everything that is referenced by the SID in the listener. If it is an Oracle database, then you are linked to the database. If this is an entry of gateway referenced by having the (HS = OK) then you are linked to the gateway which then liaises with what non-Oracle database is accessible through the gateway of the option.  You cannot directly connect to the non-Oracle database by using the IP address of machine non-Oracle in tnsnames.ora. You need to go through the door entry referenced by the listener to establish the connection.

  For the listener, you can set the path to the ORACLE_HOME of the gateway or RDBMS. However, the best option is to give the listener a different name from the default, so for the gateway, you might have-

  SID_LIST_LISTENER_GTW =

  (SID_LIST =

  (SID_DESC =

  (SID_NAME = GS2PIASQL03)

  (ORACLE_HOME=S:\app\oracle\product\11.2.0\tg_1)

  (PROGRAM = dg4odbc)

  )

  )

  LISTENER_GTW =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SLPIAM29)(PORT = 1525))

  (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1525))

  )

  )

  You can then use-

  stop LISTENER_GTW

  Start LISTENER_GTW

• 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.

• Link to database for MySQL with Oracle Express

  Hello Oracle Community,
  
  I made a post on this topic already in the section general, but here is the best place for my question. My goal is to access a mysql to oracle server. Some info about my system and what I've done so far:
  
  Windows Vista 64-bit
  Oracle Express 10.2
  
  -installed 32-bit DNS ODBC driver for the database mysql, tested and it succeeded, the name is CHANCE

  -new section in the listener.ora: (SID_DESC = (SID_NAME = CHANCE) (ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server) (PROGRAM = hsodbc))
  -new section in my tnsnames.ora: CHANCE = (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp) (HOST = GOGAPC01001)(PORT = 1521)) (CONNECT_DATA = (SID = CHANCE)) (HS = OK))
  -inexplicable the listener
  -Do a bit of luck, success of tnsping
  -created a link of database: CREATE DATABASE LINK LUCK24 CONNECT TO 'user' IDENTIFIED BY 'password' USING 'LUCK24 ';

  can anyone help?
  
  Ikrischer

  Ikrischer,
  On which platform do you have installed the drivers 32 bit and HSODBC? He was on a Windows 32-bit platform? It is not supported to run the 32-bit software on a Windows 64-bit platform.
  There were some problems with versions 10.2.0.3 and earlier that are similar to those you typo - problems with bigint and select count. These are laid down in the 10.2.0.4 group of patches, so you should apply to your ORACLE_HOME 10.2 directories and see if the problem still occurs.
  However, as already said HSODBC 10.2 is now desupported you need to find to install 11.1.0.6 DG4ODBC and then apply the 11.1.0.7 patch group which also solves the problem.
  If you have access to My Oracle Support then see this note.

  Select columns MySQL Bigint use HSODBC returns an incorrect value when you use ODBC MySQL Connector (Doc ID 401086.1)

• Execution of the SQL query through 2 different databases to Oracle

  Hi all
  
  In Microsoft SQL server, we can run on 2 different databases depending on the type of SQL query:
  
  Select * from TEST1.dbo.GENERIC_TABLE1 union select * from TEST2.dbo.GENERIC_TABLE2;
  
  Test1 and TEST2 here is 2 different databases.
  
  Can we do the same in Oracle?

  Of course you can do it.
  Create a [database join | http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_5005.htm] from DB1 to DB2.

  Grant select on the tables of the DB2 schema with which you want to connect.

  And then, you can you can query as

  select * from DB1schema.emp
  union
  select * from emp@dblink_name;

• Give advice about uninstalling the database Client Oracle under Windows with multiple Oracle homes

  Hi all.

  Probably a Client of Oracle database uninstall will arrive in a Windows box, where there are several houses of Oracle:

  (1) the Oracle Database 11 g Client is.

  (2) the House of Oracle Oracle database server.

  (3) oracle 6i Oracle Home.

  I have these concerns:

  (1) do I stop Oracle Services NOT related to the Oracle Home being deleted? I guess that's not necessary, but it is recommended?

  (2) the YES program to run must be or is better to use the YES program located at removed Oracle (Oracle Client to Database 11 g in this situation)?

  "(3) I see there are additional post - installation according to section 5.3 steps"manually remove the Oracle database Client components remaining' the Oracle Client Installation Guide for Windows.

  Could someone provide the additional steps or recommendations?

  Sorry but I do not trust the windows plataform much!

  Thanks in advance!

  Best regards, Luis!

  Hello myluism,

  You can use the oracle supplied binary dinstall to uninstall oracle binaries that you can download from this url of Oracle Database 11 g Release 2 for Microsoft Windows (x 64) that looks good in your context.

  In addition, you can also uninstall the binary files by running the dinstall respecitive houses Oracle located in the path: ORACLE_HOME\dinstall.

  Please go through the url: https://docs.oracle.com/cd/E11882_01/install.112/e47959/deinstall.htm#NTCLI1326

  I hope this helps.

  Thank you and best regards.

• Link to database not be created using a stored procedure

  Hello

  I am creating a link of database using a stored procedure.

  Here is the code for it

  CREATE OR REPLACE PROCEDURE create_db_link (ca_db_name IN VARCHAR2,

  ca_service_name IN VARCHAR2)

  AUTHID CURRENT_USER IS

  BEGIN

  EXECUTE IMMEDIATE ' create public database link test_db_link connect to ca_db_name identified by ca_db_name using "ca_service_name" ';

  END create_db_link;

  During execution of the code is created the db_link. But, when I ask all_db_links I get the following result.

  OWNER

  ------------------------------

  DB_LINK

  --------------------------------------------------------------------------------

  USERNAME

  ------------------------------

  HOST

  --------------------------------------------------------------------------------

  CREATED

  ---------

  PUBLIC

  TEST_DB_LINK. WORLD

  CA_DB_NAME

  ca_service_name

  20 Aug 13

  Could you please help me understand why it shows the parameter names in the name column of the USER and the HOST instead of the name of the database and the name of the service?

  This is to show exactly what you said to do.

  Did you expect that Oracle would read as if by magic through your string you passed to run immediately and magically know to replace all occurrences of the string that correspond to local (or even global) parameter/variable names with the values of these variables?  It does not work like that.  You could concatenate the values into the string.

  for example

  EXECUTE IMMEDIATE ' create public database link test_db_link connect to ' | ca_db_name |' identified by ' | ca_db_name: ' using the "' | ca_service_name | " ' ;

  But why are create you database links running?  Shouldn't this be part of the design of your application and the initial fact before the application runs?

  Note:
  The highest observed reaction time for a destination may not exceed the highest specified NET_TIMEOUT value specified for this destination, because synchronous transport mode sessions again are complete if a redo transport destination does not respond to a message from transport to redo a few seconds NET_TIMEOUT.

• application for registration without database through MobileAdf

  Dear all,
  
  We are developing an application without database through MobileAdf.
  I don't have to provide a database in this application.
  I'm not able to find a tutorial for it.
  Please suggest a link for this tutorial.
  
  
  
  Thanks in advance.

  If we are talking about the ADF Mobile Browser, then similar to regular ADF, the app can be supported by a variety of non DB back ends.

  If we talk about ADF Mobile Client (I suppose that this is the case), then the tech preview version only supports based on DB - app. However, in the production version that will be published soon, the app can also be supported through Web Services (via WS Data Control) to access SOAP-based web services. Alternatively, you can write custom code to access resources local/no DB if necessary - for example if you have local XML data you need to access. For example, you can write a managed bean to access this source of XML data.

  What is the use case, incidentally?

  Thank you
