How to create dblink between oracle 10G and mysql

I want to create dblink between oracle 10G and mysql
I create it in ECC6.0 using DBCO transaction tcode,which database type can choose?Microsoft sql server?Because there have no mysql item.
I choosed MSS so that I can test it, but it failed,there is an error that 'ORA-12569:TNS:packet checksun failure'.
I configured the oracle tnsnames.ora file like this:
     CW.WORLD =
           (DESCRIPTION =
                (ADDRESS_LIST =
                      (ADDRESS =
                              (COMMUNITY = SAP,WORLD)
                              (PROTOCOL = TCP)
                              (HOST = XX.XX.XX.XX)
                              (PORT = XXXX)
               (CONNECT_DATA =
                    (SID = XXX )
               (HS = ok )
When I tnsping CW,it will fail,like this " TNS-12569:TNS:packet checksum failure"
How can I do.

I want to know if this possible?

Important differences between oracle 10g and 11g

Hi friends, can anyone tell me (pointwise) what are the major (and minor) differences between Oracle 10g and 11g.
Please point me to some documents if possible.
Thanks in advance

The name of the link says it all: "top_features."
In short it is Oracle's list of what they have for marketing and sales reasons designated "top features."
It is not intended to be, and is not, a complete list of features. Often the features Oracle does not
talk about are the most important.
Let me give you some examples. I have never seen Oracle announce DBMS_XPLAN as a new feature
yet you should not run an explain plan without it. Neither have I ever seen Oracle announce the new
NO_DATA_NEEDED predefined exception. I have listed literally hundreds of new features you will not
find in Oracle's new features docs.
I did a presentation at OpenWorld this year as part of the unconference titled "New Features in
Database 11gR2 that Oracle will not announce." It was easy to prepare a one hour presentation with
little fear of being proved incorrect. As I turned out only one of the features I presented was mentioned
by Oracle.
You can find the presentation slides here:

How to provide joins between oracle tables and sql server tables

Hi,

Heterogeneous joins do not exactly scale and performance can be severely degraded by network speed and b/w availability. And there is nothing you can do in the application and database layers to address performance issue at the network level in this case - your code's performance is simply at the mercy of network performance. With a single glaring fact - network performance is continually degrading. All the time. Always. Until it is upgraded. When the performance degradation starts all over again.
If the tables are not small (few 1000 rows each) and row volumes static, I would not consider doing a heterogeneous join. Instead I would rather go for a materialised view on the Oracle side, use a proper table and index structure, and do a local database join.

How to do integration between Oracle 11g and SAP Data services

HI All,
i want to load data from Oracle 11g data base to some other data bases. we have installed oracle 11g server in one machine and Data services server in one machine.we installed oracle 11g client in data services server machine . i created data store for oracle and when i was executing job i got the following error.
how to resolve this issue. do i need to do any configuration between two servers (Oracle 11g and data services), and do i need create ODBC for oracle in data services machine.
if any one know the solution please help me out ASAP.

How to create ODBC connection between Oracle 10g and MS SQL Server

Hi,
Can someone help us with the steps to create an ODBC connection between Oracle APPS using Oracle 10g database and MS SQL Server.
Requirement is to extract the transactional data from MS SQL Server on a daily basis and dump it into Oracle tables for an interface to be run. Currently it is being done through Dataloader tool which we feel is causing the data issue with Arabic characters. We want to create the ODBC directly between Oracle and MS SQL Server and check if the data is being pulled correctly.
The data is in sql server 2000 which has data in Arabic_CI_AS character set which is moved to Oracle 10.2.0.3 database with characterset AL32UTF8. The table data is moved to oracle using the dataloader 3.6 standard edition licensed version. We cannot change the character set of Sql Server 2000.
Please help
Thanks
Shanil

Hi,
If you're trying to PULL data from SQLServer into an Oracle database, you wouldnt use Oracle ODBC driver for that, so you may want to post in the Heterogeneous Services forum instead:
Heterogeneous Connectivity
If you're trying to PUSH data from SQLServer into an Oracle database, you could use ODBC but most folks use OLEDB for that, and the following note on MOS should help:
How to Create a Sql Server Linked Server With The Oracle Provider for OLE DB (Doc ID 191368.1)
As with any NLS related issue, the first thing to do is dump the codepoints of the data in the Oracle database to see if it is stored validly, rather than relying on what the data "looks like" from some tool or other. It's best to check a single row, with only a few characters in it if you can, and you can do that via
SELECT DUMP(<columname>,1016) FROM <tablename> WHERE ...
Hope it helps,
Greg

DB Link between Oracle 10g and Oracle 9i for CLOB data type

How do I transport XMLType or CLOB from oracle 9i to Oracle 10G using DBLink?
Is any restrction to DBLink, while transfering CLOB with XML data from oracle 9i to Oracle 10G?
Please let me know how i resolve this issue.
Thanks in advance.
DK

Well... it depends on what type of link you wish to create.
If you have same user with same password on both databases (9i and 10G), then you can create a public database link as
CREATE PUBLIC DATABASE LINK dblink USING 'dbalias';
Note: dbalias is the value from your TNSNAMES.ORA. The database from which you are creating the db link has to have the entry in TNS for other database.
Other method is to create a private db link
CREATE DATABASE LINK dblink CONNECT TO user IDENTIFIED by pwd using 'dbalias';
The number of open connections from a particular database is governed by init parameter DB_LINKS (this was in 8i.. not sure about higher versions)

Issue with materialized view and fast refresh between Oracle 10g and 11g

Hi all,
I've hit a problem when trying to create a fast-refreshable materialized view.
I've got two databases, one 10.2.0.10, another 11.2.0.1.0, running on 32-bit Windows. Both are enterprise edition, and I'm trying to pull data from the 10g one into the 11g one. I can happily query across the database link from 11g to 10g, and can use complete refresh with no problem except the time it takes.
On the 10g side, I've got tables with primary keys and m.v. logs created, the logs being of this form ...
CREATE MATERIALIZED VIEW LOG ON table WITH PRIMARY KEY INCLUDING NEW VALUES
On the 11g side, when I try to create an m.v. against that ...
CREATE MATERIALIZED VIEW mv_table REFRESH FAST WITH PRIMARY KEY AS SELECT col1, col2 FROM table@dblink;
... I get an ORA-12028 error (materialized view type is not supported by master site).
After running the EXPLAIN_MVIEW procedure it shows this;
REFRESH_FAST_AFTER_INSERT not supported for this type mv by Oracle version at master site
A colleague has managed to build a fast-refresh m.v. from the same source database, but pulling to a different one than I'm using; his target is also 10g, like the (common) source, so I've no idea why I'm getting the 'not supported' message whilst he isn't.
I've been able, on previous projects, to do exactly what I'm trying to achieve but on those someone with more knowledge than me has configured the database!
I'm now stumped. I'm also no DBA but despite that it's been left to me to install the new 11g database on the 32-bit Windows server from scratch, so there are probably a couple of things I'm missing. It's probably something really obvious but I don't really know where to look now.
If anyone can give me any pointers at all, I'd be really grateful. This question is also duplicated in the Replication forum but hasn't had any replies as yet, so I'm reproducing it here in hope!
Thanks in advance,
Steve

Hi Steve,
You should have a look at metalink, Doc ID 1059547.1

Database links between Oracle 10G and 7.1/7.3 & 8.0 databases

Hi All..
Unfortunately one of our customers is still using very very old unsupported versions of the database - 7.1 and 7.3 and 8.0. They wish to start an upgrade process - moving up to 10G (via staged upgrades) but wish to know whether they can still access information from old databases via database links.
I know that the Oracle 10G client cannot connect to database versions this old, and I am presuming that the database itself cannot via DB links but I thought it wise to check.
Any help appreciated. Thank you.

Oracle 10.1 is certified to connect to 8.1.7 and later. Database links to earlier versions are not certified and generally do not work.
The general solution to this sort of thing tends to be putting an older version of the database (8.1.7 or 9.0.1, usually) between the ancient databases and the new database. 10.1 can create a database link to 9.0.1. 9.0.1 can create a database link to 7.3.4 and create views that reference remote 7.3.4 objects that the 10.1 system can query. Of course, you're taking data over the network twice, so performance isn't ideal, but it can work in a pinch.

HSODBC connectivity between ORACLE 10g and SQL Server 2008 R2

I'm getting the above error for DB links between Oracle 10.2 and SQL Server 2008 R2. But the same, when configured for MS SQL server 2000 works fine without any issues.
Please advise me to rectify the error. We've been working for the last couple of weeks.
Regards,

Sunil,
You don't need an Oracle ODBC driver.
The way it works is that in the gateway init<sid>.ora file, in your case initTelemetryDB1.ora, the parameter HS_FDS_CONNECT_INFO points to a system DSN. This DSN should then be configured to use an ODBC driver to connect to the non-Oracle database. So, in your setup when you want to access the SQL*Server 2008 database then the DSN should use an ODBC driver that can connect to a SQL*Server 2008 database. If you still use the initTelemetryDB1.ora file for the connection then the TelemetryDB1 DSN should be configured to access the SQL*Server 2008 database.
However, there are a couple of problems with your actual setup -
- the configuration you have - 10.2 RDBMS on a Sun machine and HSODBC on Windows - is not supported. HSODBC should only be used from a RDBMS that is in the same ORACLE_HOME as HSODBC.
- 10.2 HSODBC is now desupported and has been replaced by the 11g Database Gateway for ODBC (DG4ODBC) and the configuration you want is supported. That is because unlike HSODBC the DG4ODBC gateway can be installed standalone with a RDBMS being installed.
I recommend that you download and install 11.20.2 DG4ODBC on your Windows machine in a new Oracle_home and access that from the 10.2 RDBMS on Sun - which is a supported configuration. But to do this, you will need to apply either the 10.2.0.4 or 10.2.0.5 patchset to your RDBMS.
There is more information in the following note available on My Oracle Support (MOS) -
Note.1083703.1 Master Note for Oracle Gateway Products
The 11.2.0.2 DG4ODBC can be downloaded from MOS as patch and for the gateways on Windows 32-bit you just need to download -
p10098816_112020_platform_4of6.zip
However, to check the HSODBC ou need to confirm that the DSN used by HSODBC points to a System DSN configured to access SQL*Server 2008.
Have a look at -
Note 109730.1 How to setup generic connectivity (HSODBC) for Windows NT
But remember this is not a supported version or configuration and you should be using Dg4ODBC.
Regards,
Mike

How to replicate data between Oracle db and SQL server dbs in real time?

Hello,
Anyone has idea that what tool we can use to do data replication in real time between Oracle and SQL sever or Oracle and Sybase or Sql server and Sybase?
This is topic is brought by a project manager?
I only know Oracle to Oracle dbs by streams or GoldenGate.
Thanks
Jerry

Since GoldenGate's bread and butter was (and is) replicating data between heterogeneous data sources, and since Oracle has purchased GoldenGate, that would seem like a natural place to start.
Beyond that, it depends on the architecture you want and how you define "real time." Just about any ETL tool on the market, whether Oracle's ODI or OWB or any number of third party products (Informatica, DataStage, etc) can handle "trickle feeds" from various data sources to a database target of your choosing. Different tools will have different sorts of integration with the source database, many will require that a bunch of triggers are created to track changes on the source systems.
If you want Oracle to control the replication process (which doesn't really make sense if we're talking about replication from a non-Oracle database to another non-Oracle database), you can use the Oracle Transparent Gateway products to create database links from Oracle to the non-Oracle databases and query data on the source database periodically.
