COMAPRING TABLES BETWEEN ORACLE AND SQL

HI GUYS
I HAVE 2 DIFFRENT SERVERS(ORACLE(ERP),SQL SERVERS)
I WANT TO COMPARE THESE 2 TABLES IN A BEST AND EASY WAY I CAN CREATE PACKAGE CONTAIN SOURCE LOOKUP ETC
BUT I WANTED TO DO IT IN STORED PROC
HOPE IT IS A CHALLENGING QUESTATION
THANKS IN ADVANCE

Hi ADKR,
then linked the Oracle server to the SQL Server one and then you can write a stored procedure that for example encapsulates the T-SQL Merge statement (if supported by your SQL Server version).

Question about transfer between oracle and sql server

Could i program to transfer lots of data between Oracle and SQL Server quickly?
I have tried make two connection between two databases, but it took me lots of time to transfer data.
How could I do it?
Thanks

Hi,
If you need to move data fast, then use the Oracle Migration Workbench to Generate SQL Server BCP data extraction scripts and Oracle SQL Loader files.
This is the fastest way to migrate the data.
In the Oracle Model UI tab of the Oracle Migration Workbench, right mouse click on the tables folder. there is a menu option to 'Generate SQL Loader ...' scripts. This will help you migrate your data efficiently.

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.

Replication between Oracle and SQL Server

Does anyone have any experience with replicating data between SQL Server and Oracle database system? If so, I am experiencing time out errors when replicating data. I replicating from SQL Server 2k to Oracle and it time out on the Oracle side.

how to configure my apply process to work with sql server by getway , I want to make replication
note :
I make dblink between oracle and sql and make insert from oracle to sql
is it sufficient to make replication by OEM between oracle and oracle and then add new apply process to work with gateway for sql server and how ?

Database link between oracle and sql server

dear all,
i m a newbie to oracle and i need your help to know how to create a database link between oracle and sql server.my oracle version 10.2.0.3 and platform is redhat linux 5.7.your help appreciated.
thanks in advance.

Data sync between oracle and sql server

Greetings Everyone,
Your expert views are highly appreciable regarding the following.
We at work are evaluation different solutions to achieve data synchronization between oracle and sql server data bases. Data sync i mentioned here is for live applications. We are runnign oracle EBS 11i with custom applications and intending to implement a custom software based on .NET and SQL Server. Now the whole research is to see updates and data changes whenever happens between these systems.
I googled and found Oracle Golden Gate, Microsoft SSIS, Wisdom Force from Informatica....
If you can pour in more knowledge then it's great.
Thank You.

Most of the work involved has to be done through scripts and there is no effective GUI to implement OGG.However using commands is not vey togh and they are very intutive.
These are the steps, from a high level:
1.Get the appropriate GG Software for your source and target OS.
2.Install GG on source and target systems.
3.Create Manager and extract processes on source system
4.Create Manager and replicat processes on target system
5.Start these processes.
First try to achieve uni-directional replication. Then Bi-directional is easy.I have implemented bi-directional active active replication using Oracle DBs as source and target. Refer to Oracle installation and admin guides for more details.
Here is a good article that may be handy in your case.

Developing database views between Oracle and SQL Server tables

I am on Oracle 10.2, my organization has many SQL Server databases as well and has now made
SQL server as company standard so many new databases will be developed in SQL Server. It is of course
not possible to convert all Oracle databases to SQL Server, so a mix environment will exist. Two questions:
1. Is it possible to develop database views in Oracle (10g in my case) which join Oracle tables with tables in SQL Server 2008? If yes, how. I have seen some heterogeneous connectivity setup to connect SQL Server to Oracle, but not sure whether it is possible to develop a database view across two databases.
2. I know it is not a SQL Server forum, but many DBA’s know both Oracle and SQL Server. Is it possible to develop views in SQL Server (SQL Server 2008 R2 in my case) which join Oracle 10g and SQL Server 2008 tables? I know in SQL Server, there is way to set up linked servers, but do not know whether it is possible to develop views.
Thanks a lot for your insight.

You can create views that join local Oracle tables and remote SQL Server tables. I'm pretty sure you can do the reverse as well but I haven't personally done it.
However, I would be very concerned about the performance you'd get if you created that sort of view. You'd very frequently end up in a situation where Oracle has to pull all the data in the remote table across the database link in order to apply predicates and join the data locally. That could be disastrous from a performance standpoint.

Sorting differences between Oracle and SQL Server

Hello All,
This question is related to both Oracle and SQL Server
I have a requirement where I want to compare 2 tables line by line. One table is in Oracle and other table is in SQL Server
And suppose that both of the tables don't have a primary key. Now when I sort the records using order by clause for a column then -
Rows having null values in that column of Oracle are placed at the bottom.
Where as Rows having null values in the same column of SQL Server are placed right at the top.
How can I make either of them to behave like other.
My sole aim is to have same order of occurrence of rows in both Oracle and SQL Server tables so that I can compare them line by line.

For example :
select * from emp order by comm;
So all null value in comm column are at the end.
Now if you wish to get them on the top of select output then :
SELECT EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,NVL(COMM,0) COMM,DEPTNO FROM EMP ORDER BY COMM;
Means i am using NVL (oracle function) function. If comm column is having null value it will converted to zero value at the time of exectuion of select query.
So, now comm column is having zero value in select output and SQL Server is having nulls at the top. I do'nt know who to make nulls to zero in SQL Server. So issue solved.

Need To Create a table in Sql Server and do some culculation into the table from Oracle and Sql

Hello All,
I'm moving a data from Oracle to Sql Server with ETL (80 tables with data) and i want to track the number of records that i moving on the daily basis , so i need to create a table in SQL Server, wilth 4 columns , Table name, OracleRowsCount, SqlRowCount,
and Diff(OracleRowsCount - SqlRowCount) that will tell me the each table how many rows i have in Oracle, how many rows i have in SQL after ETL load, and different between them, something like that:
Table Name OracleRowsCount   SqlRowCount  Diff
Customer                150                 150
0
Sales                      2000                1998
2
Devisions                 5                       5
0
(I can add alot of SQL Tasks and variables per each table but it not seems logicly to do that, i tryid to find a way to deal with that in vb but i didn't find)
What the simplest way to do it ?
Thank you
Best Regards
Daniel

Hi Daniel,
According to your description, what you want is an indicator to show whether all the rows are inserted to the destination table. To achieve your goal, you can add a Row Count Transformation following the OLE DB Destination, and redirect bad rows to the Row
Count Transformation. This way, we can get the count of the bad rows without redirecting these rows. Since the row count value is stored in a variable, we can create another string type variable to retrieve the row count value from the variable used by the
Row Count Transformation, and then use a Send Mail Task to send the row count value in an email message body. You can also insert the row count value to the SQL Server table through Execute SQL Task. Then, you can check whether bad rows were generated in the
package by querying this table.

Data type conversion issues between Oracle and SQL Server

Hi there, I am using Heterogeneous Services to insert into a SQL Server database. I am running into an issue between data types regarding Oracle's VARCHAR2 and trying to insert that into a SQL Server MONEY data type. I tried using the TO_NUMBER() function to convert my VARCHAR2 to a number, but that didn't seem to help.
Does anyone have any advice on how to work around this??
Thanks for any help,

Urgent: \connectivity between oracle and SQL Server

Hi I have a problem, a person in some of the dept's in office created a small oralce forms application that uses a oracle db10gr2 installed on personal pc (windows xp)to connect to a sql server to pull data. Recently the sql server was upgraded to blade 2008 from blade 2003. Then aplication stopped connecting correctly I think it has to do with the listener but not sure where the problem lies.

Hi,
the system dsn works fine it even tests correctly, but teh database link does not work even for something as simple as
select sysdate from dual@person;
the db link is a public one so priviledges should not be an issue and the command i used to create it is:
create public database link person connect to USER identified by pwd using 'person';
also unfortunately this is an employee initiative (said empoyee has left without documentation or notes) and there is no oracle support.
thanks in advance.

Differences between being an Oracle and SQL DBA?

Sorry to post this here, but I need so insight and don't know any Oracle DBA's. As posted here before, Ive been a MSSQL DBA for about 6 years and want to broaden my skill set. One of my ideas is to learn Oracle. For the record, I do realize that my teaching myself wont open up hundreds or Oracle DBA jobs, but Im hoping to land a "mostly SQL with a little Oracle" gig somewhere. Ive successfully installed Oracle on Linux, and now need to make a decision on if to proceed or not. Any insights from people that have worked with both platforms would be especially helpful, but all thoughts are definately welcomed. So now my questions:
1. Why are Oracle DBA's paid more than SQL DBA's? It must be something skill specific? What is it?
2. Will this trend likely continue as newer versions of Oracle are released that are easier to manage?
3. With that extra cash, is there typically more hours involved? I dont mind working a bit extra if needed, but I do have little ones that I'd like to watch grow up.
4. Are there typically differences in the job responsibilities between Oracle and SQL DBA's? The changing trend these days is to include DTS/ Analysis Services/ Reporting Services all under the DBA umbrella. Do Oracle DBA's typically have the same type of stuff?
5. If I do continue down this path, it would probably be far easier for me to learn on Windows than *nix. Is this a valid thing to do, or should I not bother? I've been told that it's still worth while, but have real reservations about needing to tell an interviewer "I've only used it on Windows".
I realize this is all subject to personal experiences and feelings, but don't know how else to figure this stuff out without asking.
TIA, ChrisR

By SQL DBA, I assume you mean SQL Server DBA. SQL is 'Structure Query Language' and is not a specific product, no matter how much the Microsoft community might wish to usurp the term. <g>
There are mauy reasons for this, including the Oracle vs Microsoft mindset that has been nurtured over the years. For many managers, 'Oracle is solid, reliable and expensive' whereas 'Microsoft SQL Server is cheap, not necessarily as reliable, but good enough'.
Whether true or not is irrelevant, these are direct quotes from some of my customers.
My remaining answers are based on my personal experience, and may only be valid in my area. (Yes, things are VERY regional.)

1. Why are Oracle DBA's paid more than SQL DBA's? It
must be something skill specific? What is it? Often, an Oracle DBA is a trained DBA. SQL Server DBAs seem to be decent developers who are [or have been stuck] doing DBA work.
I find that SQL Server DBAs who are truly capable of handling all of {backup, recovery, troubleshooting, security, development, disaster recovery, audit, locking, configuration, RAID and disk, upgrade, migration and porting (to name a few)} competently are generally paid comparable to Oracle DBAs.
However, I also find there are extremely few true SQL Server DBAs.

2. Will this trend likely continue as newer versions
of Oracle are released that are easier to manage?Yes.
Although Oracle administration is easier, DBAs are now expected to handle more instances, and adminstrator across more servers, and are expected to be competent in more of the feature capabilities.
There is NO reduction in the amount of work. The 'easier to manage' stuff simply means being more efficient.
>
3. With that extra cash, is there typically more
hours involved? I dont mind working a bit extra if
needed, but I do have little ones that I'd like to
watch grow up.
A blatant observation: Oracle tends to be used in more mission critical environments, and SQL Server in department support environments. Mission critical tends to be watched closer, and require 'fast aqnd competent' response. Pager duty seems to be more prevelant in Oracle positions - department server crashes can be handled by a reboot in the morning.
4. Are there typically differences in the job
responsibilities between Oracle and SQL DBA's? The
changing trend these days is to include DTS/ Analysis
Services/ Reporting Services all under the DBA
umbrella. Do Oracle DBA's typically have the same
type of stuff?Many SQL Server 'DBAs' I know personally are 'super developers' but not really DBAs.
Observation: DBAs are often very 'repeatable' detail oriented, whereas developers are 'get it done' oriented. Very different mentailties, both very important.

5. If I do continue down this path, it would probably
be far easier for me to learn on Windows than *nix.
Is this a valid thing to do, or should I not bother?
I've been told that it's still worth while, but have
real reservations about needing to tell an
interviewer "I've only used it on Windows". Oracle is quite operating system independant. Pick your poison.
SQL Server is quite operating system dependant. Some else picks your poison.
There is no shame in saying to an interviewer that you have a strong competence in Oracle but only experience in Windows. A good potential employer will often provide appropriate additional training to a suitable, honest, candidate.

I strongly encourage you to contact locals rather than ask in these forums. Check whether there is an Oracle User Group close to you, and meet and chat with the members. Ditto for SQL Server. (You can find out by contacting respective sales reps.)
The above is NOT a dismissal of SQL Server capabiltites or SQL Server DBAs. (Some close friends are extremely competent with SQL Server.) It is just a set of personal observations.

Data Sync between ORACLE and SQLServer

Hi,
I would like to here the possible options for "Bi-Directional Data Sync" between ORACLE 10g (Enterprise Edition Release 10.2.0.4.0) and SQL Server 7.0 (7.00 - 7.00.961 Standard Edition on Windows NT 5.0 ).
Please let me know the available tools or any other addons.
thanks and regards,
Suman.S
