How to create database link between oracle and SQL Server
Hello Everyone,
Here i have Oracle Database 9i and SQL Server 2005 databases.
I have some tables in sql server db and i want to access from Oracle.
How to create a database link between these two servers
Thanks,Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a) Oracle 10g software
b) User account to access SQL Server database (sa/abc@123!)
c) Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1) Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2) Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3) Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4) Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =
(SID_LIST =
(SID_DESC =
(SID_NAME = SQLTEST) *+< Here SQLTEST is DSN NAME >+*
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc))
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5) Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6) Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora
something=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST =192.168.0.175) (PORT=1525))
(CONNECT_DATA=
(SID=SQLTEST))
(HS=OK)
$ tnsping something
$ sqlplus system/manager
Your connected to Oracle database *(machine 1)*
create database link xyz connect to “sa” identified by “abc@123!” using ‘SOMETHING’;
select * from t@xyz;10 rows selected.

I have Windows XP with 10.2.0.1.0
I have made my database global_name to be junk.points.com.
And, I create a database link as:
create database link preview using 'xxxxx';
the db_link is preview.point.com.
However, if I use the following command:
create database link preview.system using 'xxxxx';
the db_link is preview.system instead of preview.system.points.com.
I expect the db_link should be preview.system.points.com. Please help.
ThanksHi,
Specify the complete or partial name of the database link. If you specify only the database name, then Oracle Database implicitly appends the database domain of the local database.
If the value of the GLOBAL_NAMES initialization parameter is TRUE, then the database link must have the same name as the database to which it connects. If the value of GLOBAL_NAMES is FALSE, and if you have changed the global name of the database, then you can specify the global name.
Defining a CURRENT_USER Database Link: Example
The following statement defines a current-user database link to the remote database, using the entire service name as the link name:
CREATE DATABASE LINK remote.us.oracle.com
CONNECT TO CURRENT_USER
USING 'remote';
The user who issues this statement must be a global user registered with the LDAP directory service.
Please view the below document.
http://www.stanford.edu/dept/itss/docs/oracle/10g/server.101/b10759/statements_5005.htm
http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/ds_admin002.htm
And please check the db links you posted one is having __.point.com
and the other one is having ___.points.com
Please make sure you are using the GLOBAL_NAMES set true and displaying correct dblink .
Hope this will be helpful :)

We are running Portal 3.0.9.8.0. I am wondering if anyone has come across away to disable the ability of users to create database links.
Hi,
You can do it only by revoking the "create database link" or "create public database link" privilege from the database schema
to which the portal user is connected.
For example say there is a user "erin" mapped to the database schema portal30, then you should go to the
"Administer Database" tab and edit the schema using the "Schemas" portlet. In the roles tab remove "create pubic database link"
or "create database link" privilege.
This might help. But be careful not to remove the privilege from the portal schema, unless you do not want to create any
database links as the portal schema.
Thanks,

DB Links with 11g and 8i Databases.
Hello,
Does anyone know if an 11g database listener will link to an 8i database listener ?
Thanks.Hi,
AFAIK, I have not tested, but it should work, since their are not huge process changes with respect to listeners.
I might be wrong too.

Link between data dictionary and database
Hi friends,
I have created a ztable through SE11 and when i activated it a copy of it gets created in the database.
know i know that iam creating it at the application layer level now when upon activation how does it gets created in database.
what exactly is the linkage between application and database.
can any one tell me
Regards
Satish KumarHi
In the databse it's created a table with the same name of dictionary table, u should get a book of SQL command, or see the SQL command in Internet, for example search the command CREATE TABLE

Link between LANDSCAPE AND R/3
hi gurus i have doubt. that what is the difference between DEV,QUALITY AND PRODUCTION SERVERS AND DATABASE, APPLIACATION, PRESENTATION.
initailly while we are in implementation we use DEV,QUALITY AND PRODUTION.
after impllementation DATABASE, APPLICATION AND PRESENTATION comes into picture. so in landscape good configuration sits in production server. so for end user point of u PRODUCTION SERVER WILL BECOME DATABASE SERVER OR NOT. pls tell me the link between landscape and R/3.
will rewardHi Krishna,
I think you are trying to mix 2 questions.
Well you can frame the questions like this:
1) Difference between Development, Quality and Production Servers
2) Database, application and presentation layer.
Well the point1) refers to Landscape. What happens is when are working for any end to end implemetation or support project we need certain instances so we can have instances like Development, Quality and Production. we have got different instances because we need to test whether the changes made are working as per the requirements.
Point 2) refers to R/3 technology.
SAP R/3 is based on a three tier client/server technology. Typically, it is made up of three functionally distinct layers namely: the user interface, business logic and database.
The user interface, which is otherwise known as the presentation server displays the interface for users' communication with the SAP system. It is often referred to as the SAP GUI. As a matter of fact, it is a program called sapgui.exe. The application server is where the business logic and data manipulation takes place. Data processing, SAP administration tasks and client request/feedback management are handled within the business layer. The database layer is synonymous to the database server and it typically acts as a data repository for tables and other database objects and structures.
Ideally, an R/3 system is composed of one database server, one or more application servers and one or more presentation servers.
Hope this helps you.
Do award points if you found them useful.

hi gurus
iam confused pls tell me what is the difference between production and database server. or both are same. because all customizations and configurations are trasported to production server, later will be done golive. but one of my freinds that database server contains customizations and master records which is nothing but production server. so consultants point of view it is production server and enduser point of view it is database server. pls clarify the link clearly between dev,qual and prod ; database, application and presentation
will rewardHi Krishna Prasad,
Presentation Layer - This is what SAP GUI is all about..ie.SAP Easy Access is called the Presentation Layer
Application Layer - This is the SAP server(wherein DEV,QUAL and PRD) will come into picture..This is interlinked with SAP Easy Access for the Business users only to fetch the data to the end user in the desired format whereas the configuration/changes ideally happen here.
Database Layer - This is your backend database which may be Oracle or SQL server based on the volume of the data(Like all the data needs to be stored in the form of individual fields in different tables based on the functionality)
Hope it helps.

String columnName = model.getColumnName(column);
Object tableModel = model.getValueAt(row, column);
// Do something with the data...
System.out.println(tableModel);
System.out.println("data"); // should output in the console
}How do we notify java that a cell on a row has changed so that we can reflect the changes to the database. The current application shows that the data in cells are editable, but when we edit a cell and hit enter, data changes back to the previous data in that particular cell. And the data as well does not change its state: for example, if a data in the table has a value of boolean value false [checkbox unchecked], I can not modify the checkbox state to checked state. The tableChanged method does not get executed, and therefore, this is a serious error that I cant figure out.
My question:
What code should I write so that I will be able to notify java of the changed cell and how do we write the code that will reflect the changed values in a cell into the database?

Re: what is difference between sap locking and database locking

what is difference between sap locking and database locking. Iam locked the table mara by using lock objects.
But iam unable to unlock the mara table. I give u the coding. Please check it.

ENDIF.Hi Paluri
Here is the difference between SAP locks and Database locks, i will try to find the solution to your code.
Regards
Ashish
Database Locks: The database system automatically sets database locks when it receives change statements (INSERT, UPDATE, MODIFY, DELETE) from a program. Database locks are physical locks on the database entries affected by these statements. You can only set a lock for an existing database entry, since the lock mechanism uses a lock flag in the entry. These flags are automatically deleted in each database commit. This means that database locks can never be set for longer than a single database LUW; in other words, a single dialog step in an R/3 application program.
Physical locks in the database system are therefore insufficient for the requirements of an R/3 transaction. Locks in the R/3 System must remain set for the duration of a whole SAP LUW, that is, over several dialog steps. They must also be capable of being handled by different work processes and even different application servers. Consequently, each lock must apply on all servers in that R/3 System.
SAP Locks:
To complement the SAP LUW concept, in which bundled database changes are made in a single database LUW, the R/3 System also contains a lock mechanism, fully independent of database locks, that allows you to set a lock that spans several dialog steps. These locks are known as SAP locks.
The SAP lock concept is based on lock objects. Lock objects allow you to set an SAP lock for an entire application object. An application object consists of one or more entries in a database table, or entries from more than one database table that are linked using foreign key relationships.
Before you can set an SAP lock in an ABAP program, you must first create a lock object in the ABAP Dictionary. -
Database link to the same database
I'm trying to create a database link to the same database.
It doesn't seem to be working ...
basically, the target system will have 2 separate database instances.
I need to emulate this in a single instance database (actually, I don't want to try running 2 oracle instances on my laptop...).
so I want to do select * from fred@MYOTHERDB
when I try and create the alias it succeeds, but then selects don't work.
Lets say my current logon / schema is JOHN (in ORCL) and the other SCHEMA (in ORCL) is JIM
I tried
create public database link MYOTHERDB connect to JIM identified by "Password";
creation worked, couldn't access it.
Thanks in advance
IainThe machine with the database has tnsnames.ora as

Now I've tried this both from TOAD and from iSQL on the machine with the database.
It's INVMANLAP which I'm using from the TOAD machine, of course!
I appreciate your help. It has been the only bright spark in a DREADFUL day (among other things the IDC-SERVER mentioned above has a trashed system disk which has taken out email and my main oracle server). And I have to install this system tomorrow!

foreach (Identifier modelId in models)
Console.WriteLine(modelId.Name);
catch (System.Exception ex)
Console.WriteLine("Error: " + ex.Message);
Console.ReadKey();Hi Jan,
For the error "The product version and database version are not compatible", as Emma said, the version number of the Service does not match the database schema version.
In your scenario, which version of database are you using? Please note that MDS update required after SQL 2012 SP1 installation, please refer to the links below to see the details.

Hi All ,
I'm facing the below error on primary while trying to create a db link pointing to the 10g standby database which is in mount stage.
SQL> create database link synct connect to system identified by 123 using 'stdby';
Database link created.
SQL> select max(sequence#) from v$archived_log@synct where applied='YES';
select max(sequence#) from v$archived_log@synct where applied='YES'
ERROR at line 1:
ORA-02068: following severe error from SYNCT
ORA-01033: ORACLE initialization or shutdown in progress
Database version is 10.2 standard edition
My requirement is i need to get max(sequence#) of standby database from primary database using db link.
what i was trying to do is
on primary get max(sequence#) & get max(sequence#) of standby using db link and compare both if the gap differene is more than 10 send a mail.

Post Standby/DataGuard/ADG all questions further in Oracle Discussion Forums » High Availability » Data Guard
If you try to connect any users other than SYS in standby the error is very much expected. Of course you can connect with other users if you open database in OPEN READ ONLY mode, from 11gRx you can connect with other users even MRP is running if you are using ADG(active Data Guard licensed) .
I like to know, what you want to achieve by creating DB Link on physical standby database? Which is not allowed.
Database version is 10.2 standard edition

Any suggestions will be really helpfulNote:- Standard edition, Data Guard not enabled.
To use this you should use Oracle Net Service, you no need of DB Links.
Ex:- sqlplus sys/****@standby as sysdba
Here standby refers to Oracle net service, Where you will have entries in $ORACLE_HOME/network/admin/tnsnames.ora file.
