Dblink from oracle to db2

Hi all,
please, can you explain me steps to create a database link from Oracle 10gR2 to DB2?

Hi,
You need to install one of the Database Gateways -
11.1 Database Gateway for DRDA (DG4DRDA)
11.2 Database Gateway for DB2 (DG4DB2)
11.1 or 11.2 Database Gateway for ODBC (DG4ODBC)
After the gateway is installed and configured then you create the database link which uses the gateway to manipulate data on DB2 - select, insert, update and delete, for example -
select * from db2_table@gateway_db_link ;
The database link is created using a tnsnames.ora entry which references the gateway setup.
There is further information on the gateways available on My Oracle Support and OTN.
If you want more specific detail then let us know -
- if you have a gateway installed already and which one if so
- what version of Oracle you are using
- platform where Oracle is running
- version of DB2 to access
- platform where DB2 is running
Regards,
Mike

Database link from oracle to db2

Can any help me to create a database link from oracle to db2. It would be greatful if you can provide me detail steps

You don't give us much information to go on. What version of Oracle? What platform is DB2 running on? You might want to take a look at this. You might also look here and here.

Re Migrating from Oracle to DB2

Hi All,
We are migrating from Oracle to DB2, so just wanted to know what will be the impact when we do this, i mean what all necessary steps should be taken to do so. I am a technical consultant involved in this project so not much idea regarding this.
Also please let me know will it effect the custom i mean the Z programs that we have created. Please let me know regarding this.
Thanks and Regards,

A heterogeneous migration (changing database and/or operating system) implies a certified migration consultant doing the migration, otherwise you'll loose support from SAP for problems during the migration and for the target system (http://service.sapcom/osdbmigration --> FAQ).
> Also please let me know will it effect the custom i mean the Z programs that we have created. Please let me know regarding this.
Depending on how you access the data you may need to increase/delete indexes or change the programs to get a better speed.

Migration from Oracle to DB2 UDB on Unix

Hi SAP Expert
We have different SAP landscape in our company on Oracle DB
Due to High Oracle Licensing cost we are planning to migrate our Database to DB2 to reduce license cost
I would like to know how Reliable DB2 is for SAP? What is % of SAP installation on DB2 worldwide
Also will there be challenge migrating DB from Oracle to DB2
I would appreciate if you can provide guidance on the question
Thanks in advace
Thanks
Deelip

> I would like to know how Reliable DB2 is for SAP? What is % of SAP installation on DB2 worldwide
DB2 was and is used on quite a number of internal SAP systems that create support packages (if you check the import logs of the support packages and search for "source system).
SAP doesn't give any exact numbers of installations compared to other databases, they did that in the past.
> Also will there be challenge migrating DB from Oracle to DB2
As with every database migration you'll have to check your custom programs and secondary indexes, backup strategies and methods and such.
> I would appreciate if you can provide guidance on the question
Be aware of the fact that you must have a certified migration consultant doing the migration on-site, otherwise SAP will deny OSS support and bill (see http://service.sap.com/osdbmigration).

SAP Database Migration from Oracle to DB2

Hi All,
Our client has decided to move the SAP database from Oracle 10.0.2 to IBM DB2. We will like to know list of activities which are required to be done from application side to support this.
Also we want to know on how to find the report / interfaces where the code is written in native SQL (PL SQL) and not in open SQL (ABAP).
Any pointers in this regard will be useful. Thanks.
Best Regards,
Vithal

Dblink from Oracle 9.2 to Oracle 7.3

I have created a link from Oracle 9.2 to Oracle 7.3 without a problem. However, when I try to use it I get the error "ORA-24439: Connections to Oracle7 server are no longer supported
ORA-02063: preceding line from link_name"
Would Heterogeneous Services help in this situation?
Thanks.
klb

I suppose you could set up Heterogenous Services, have it use an ODBC connection to the 7.3.4 database (you'd need an Oracle client install of 7.3.4 - 9.0), and then the link would work. That is likely to be a pretty significant effort, though.
Is it possible for you to upgrade the 7.3.4 database or downgrade your 9.2 database to 8.1.7 or 9.0?

Oracle DB Link from Oracle to SQL Server

Dear buddies,
I am trying to create a dblink from Oracle to SQL Server.
This is my tnsnames.ora
sq =
(DESCRIPTION=
 (ADDRESS=(PROTOCOL=tcp)(HOST=LOCALHOST)(PORT=1521)
 (CONNECT_DATA=(SID=sq))
 (HS=OK)
)This is my listener
SID_LIST_LISTENER =

 (PROGRAM = hsodbc)
LISTENER =

 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)initsq.ora
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
# HS init parameters
HS_FDS_CONNECT_INFO = sq
HS_FDS_TRACE_LEVEL = OFF
# Environment variables required for the non-Oracle system
#set <envvar>=<value>I have created my System DSN for sq with the appropriate values which works fine when I tested the connection.
These 2 databases are in different servers.
This is how I created the db link in Oracle
create public database link sq
CONNECT TO XXX IDENTIFIED BY "XXX"
using 'sq'
select "Column1"
from "Table1"@'sq';The error I receive is: ORA-01729: database link name expected
When I try to recreate the database link it tells me that: ORA-02011: duplicate database link name
I hope someone could guide me.
Thanks.

DBLink Between Oracle 8i and Oracle 9i

Hello,
Can anyone help me with this question....
Can a you create a DBLink from Oracle 9i database to Oracle 8i database (or vice versa)? Is it supported by Oracle?
AJ

Hi,
Yes it is supported and it works fine but there is a known bug.
If your 8i database is 8.1.6 and if you have a table with a LONG column in that database you won't be able to create a view in your 9i database that will access the LONG column of the 8.1.6 table. If you do that you will get an ORA-00600.
It is fix with 8.1.7.4.
Bye

ORACLE AGAINST DB2

Hello everybody,
in my company, we are running our SAP mission critical application on HP-UX systems based on Itanium tecnology.
We are using Oracle database. Oracle recently announced that it won't release anymore the Itanium certification for new versions (starting from version 12).
So, all people using Itanium with Oracle platform have to decide the way to follow for the middle-long term.
A solution should be to migrate the SAP installation from Oracle to DB2.
Can someone tell me which is the SAP position on that topic (ORACLE or DB2) and if there are benchmarks to compare SAP systems using Oracle and DB2?
Thanks in advance
Augusto

> A solution should be to migrate the SAP installation from Oracle to DB2.
Yes, or migrate to MaxDB on HP-UX, Sybase ASE on HP-UX or Windows with SQL Server
Keep in mind that IBM may to a likewise step as Oracle in the future and stop developing DB2 on HP-UX/IA64 because the marketshare is decreasing even more.
To stay with Oracle you could also migrate to Linux (on x86_64) and Oracle so you can keep your database.
> Can someone tell me which is the SAP position on that topic (ORACLE or DB2) and if there are benchmarks to compare SAP systems using Oracle and DB2?
http://www.sap.com/benchmarks
Generally all databases available and released for SAP products can be treated more or less "similar" in sense of performance. If you check the benchmarks there's not a big difference between the databases. It's more a question of features and eventually maintenance fees.

If this does not work, then Oracle HSO will also not work.
Once you have confirmed that this is working, then configure the HSO service for Oracle.
If that fails, enables ODBC client tracing for that HSO service (in the init file for that service) to see exactly what ODBC calls Oracle is making and which of these are failing.
