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

Are you looking for transactional replication between Oracle and SQL Server? Take a look at Wisdomforce [DatabaseSync.|http://www.wisdomforce.com/products-DatabaseSync.html]
It can perform a [real-time change data capture|http://www.wisdomforce.com/products-DatabaseSync.html] of transactions from redo log files and apply them into Oracle or SQL Server

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.

How to use bind_variable for connectivity between Oracle and SQLServer 2005

The code specified below could be used as an example of how to call a remote SQLServer 2005 procedure from Oracle.
The problem I am facing is that I am not able to use the dbms_hs_passthrough.bind_variable without exceptions.
Could someone help me out on this?
declare
CREATE PROCEDURE dbo.OrcaMessageTranslator
@inp nvarchar(255),
@outp nvarchar(255) output
AS
BEGIN
select @outp = @inp+'output'
END
c integer;
nr integer;
inp varchar2(255);
outp varchar2(255);
sql_stmt varchar2(32767);
begin
dbms_output.put_line('call SQLServer procedure OrcaMessageTranslator');
dbms_output.put_line('value of input variable inp is HowToReplaceThisValueByBindVariable ');
sql_stmt := 'DECLARE @outp nvarchar(255)
EXEC dbo.OrcaMessageTranslator
@inp = N''HowToReplaceThisValueByBindVariable'',
@outp = @outp OUTPUT
SELECT @outp as N''@outp''';
c := dbms_hs_passthrough.open_cursor@pp_preorca;
dbms_hs_passthrough.parse@pp_preorca(c,sql_stmt);
nr := dbms_hs_passthrough.fetch_row@pp_preorca(c);
dbms_hs_passthrough.get_value@pp_preorca(c, 1, outp);
dbms_hs_passthrough.close_cursor@pp_preorca(c);
dbms_output.put_line('acquired value of output variable outp is '||outp);
end;

Hi,
BIND_VARIABLE is useful when you have only IN variable but in your case you have IN and OUT.
I don't know if you use the gateway for MS SQL SERVER or HSODBC/DG4ODBC but here how you can do to call a remote procedure with bind variables:
DECLARE
ret integer;
inp varchar2(255);
outp varchar2(255);
BEGIN
inp :='Hello World';
outp :='';
ret := "dbo"."in_out_proc_test"@tg4msql( inp, outp);
dbms_output.put_line('Input value: ' ||v_ut1||' - Output value: '||v_ut2);
END;
The MS SQL Server procedure belongs to the user "dbo" and the database link
being used is tg4msql.
The following line initilaize the out variables of the procedure with an
empty string:
outp :=''
I hope it helps you.

Mireille

Performance EXPERT between Oracle and SQLServer!!

Hi all,
I have this query:
select t.status, count(*) from brcapdb2.titulo t
group by t.status
order by t.status;
The hardware is the same and when i run this on Oracle it takes about 20 seconds and the same query on SQLServer takes 2 seconds.
Both databases are using parallelism but the main difference is that SQLServer use an index that Oracle didn´t use. This index is created on column "status".
Even if i try to force this index with HINT on Oracle i can´t use it.
Any advice will be apreciated.
Tks,
Paulo.

I don't know anything about SQL Server, but Oracle can use an index for your query but only if all possible values of status can be retrieved from the index.
Oracle doesn't store an index entry if all indexed columns are null. So in order to give you the count where the status is null, Oracle needs to access the table.
In this example, I have a not null constraint on status:
SQL> select t.status, count(*) from titulo t
2 group by t.status
3 order by t.status;
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE (Cost=19 Card=13 Bytes=104)
   1    0   SORT (GROUP BY) (Cost=19 Card=13 Bytes=104)
   2    1     INDEX (FAST FULL SCAN) OF 'T_IDX' (NON-UNIQUE) (Cost=5 Card=7995 Bytes=63960)As you can see, it never accesses the table.
If I remove the not null constraint on the status column, it uses a full table scan:
SQL> select t.status, count(*) from titulo t
2 group by t.status
3 order by t.status;
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE (Cost=19 Card=13 Bytes=104)
   1    0   SORT (GROUP BY) (Cost=19 Card=13 Bytes=104)
   2    1     TABLE ACCESS (FULL) OF 'TITULO' (Cost=5 Card=7995 Bytes=63960)Now if I add a where clause to eliminate null values, it goes back to an index scan:
SQL> select t.status, count(*) from titulo t
2 where status is not null
3 group by t.status
4 order by t.status;
Execution Plan
   0      SELECT STATEMENT Optimizer=CHOOSE (Cost=19 Card=13 Bytes=104)
   1    0   SORT (GROUP BY) (Cost=19 Card=13 Bytes=104)
   2    1     INDEX (FAST FULL SCAN) OF 'T_IDX' (NON-UNIQUE) (Cost=5 Card=7995 Bytes=63960)Message was edited by:

Real-Time Data Sync-up between Oracle and MS SQL Server

Hi All,
I am looking for a solution to sync-up the data between Oracle and MS SQL Server in real time. Here, the structure of table is different (in the sense, the data in multiple table in SQL Server should be combined and put it in a single table in Oracle and vice versa).
Could anybody throw light on this plz?
Thanks in advance!

How can we do the data migration between Oracle Applications and SAP R/3.

Hi All,
How can we do the data migration between Oracle Applications and SAP R/3 system.What are all the possible ways to move bulk data from Oracle Apps to SAP r/3 system.
Provide any 3rd party tools which supports data migration and also pls rpovide the SAP's own data migration tools with supports the above feature.
Awaiting for best possible solution.
Thanks in advance.

Sync between MacBookPro and iPhone 3G does not sync properly. Calendars duplicate events but worse is that only contacts from Address book from letter T onwards sync. Any contacts on iPhone which are not on Mac are lost during sync.

Sync between MacBookPro and iPhone 3G does not sync properly. Calendars duplicate events but worse is that only contacts from Address book from letter T onwards sync. Any contacts on iPhone which are not on Mac are lost during sync.
Solutions?

No, I never really found an easy solution. I believe it is an issue with some corruption in the iTunes database on the specific device. In my case, both my iPad and iPhone now show duplicate stream songs if viewed through iTunes on my Mac, but they show different songs. A couple years ago I had a similar issue on my iPhone, and Apple support suggested I back up the phone, completely reset it, and then restore it from the backup. It did work, so I imagine it would probably work for my current issues with the iPhone and iPad. But resetting and restoring an iPad or iPhone always makes me a little nervous that something will get lost. When I did reset/restore the iPhone, I do have to say, the restore process was 100% perfect and I did not lose any data at all even though Apple support said I might. If you try to go that route, I would suggest backing the device up both to a computer through iTunes, and to the iCloud so that you have a double backup.
None of this really resolves the issue with how the iTunes databases are becoming corrupted on the apple devices though, so it is very likely to happen again until they fix it. I have been unable to determine if there were any specific actions or conditions which caused the corruption to happen in the first place.
Might be worth another call to Apple support, or dropping in the local Apple store if you have one near by.

In tune show all summary activity during sync between nb and apple device. One of the summary is memory space status. Audio mayb3gb, photo 2gb, app with 3gb. What is other? Other consist of what type of file?

In tune show all summary activity during sync between nb and apple device. One of the summary is memory space status. Audio mayb3gb, photo 2gb, app with 3gb. What is other? Other consist of what type of file? It show quite substantial storage capacity?? Anyone can answer what is in other??

"Other" includes data such as contact information and photos assigned to contacts, calendar events, Safari bookmarks/cookies/history, notes created with the Notes application, SMS messages, email stored locally or cached, and 3rd party application data created and stored by the application.
If "other" is more than say .75GB at the most, you had a corrupt sync. Try syncing again and if the problem persists, the recognized fix for this is to restore your iPad.

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.

What are the differences between Oracle and other NoSQL database

Hi all,
I would like to know what the differences between Oracle and other NoSQL database are.
When and why should we use Oracle?
Is Oracle NoSQL database link with Big Data Appliance?
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?
Do we also have eventual consistency with Oracle NoSQL database? Can we lose data if master node fails?
Are transactions ACID with Oracle NoSQL database? How can we prove it?
Thanks.

http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

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_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=

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 ?

Generic Insert and Update Queries to work on both Oracle and SQLServer

xMII12.0.2
I need to write queries which will be able to run on both Oracle and SQLServer database tables without any changes. It needs to be able to handle dates without including Oracle specific date functions (TO_DATE, TO_CHAR, TO_TIMESTAMP, etc.).
I did read a post earlier by Jeremy Good regarding the use of ED and SD which invoke the DatePrefix and DateSuffix in the data server configuration. That seems to work fine in cases of only trying to insert two distinct dates. However, what do you do in the case of having three or more dates to insert. An example query might be:
Insert into ProductionOrder
(ProdOrdNbr, Plant, Material, Quantity, UOM, DeliveryDate, ProdStartDate, ProdFinishDate, CreateDate, LastModifiedDate)
Values
('0100001001', '001', '000000000007887780', 20.0, 'PC', '21-FEB-08 22:01:19','11-FEB-08 00:01:34', '12-FEB-08 02:44:59', '01-FEB-08 12:00:00', '04-FEB-01 13:22:13')
So far I have been using the TO_DATE to convert the dates successfully, but SQLServer does not recognize that function (not surprising since it is an Oracle specific function). So I would have to go through all the transactions/query templates and rebuild them separately to deal with the different database vendors.
Any suggestions?
Thanks,
Mike

Hi Rick,
Are you talking about dynamically building each script based on a server setting and datatype? If I understand you correctly, I guess it could be done that way, but it would be a royal pain to maintain. I have done such things before and can see how it could be done.
But is there no way to invoke the DatePrefix and DateSuffix besides the SD and ED parameters? Or did I misunderstand your response?
I would be perfectly happy to build all the queries inside BLS transactions. In the few cases, where they are not already contained in the BLS, we could throw a BLS wrapper around it and not pay much of a penalty in performance.
Thanks,
Mike
