Heterogeneous services 10GR2 Questions
Hi,
we are planning to make a dblink connection between oracle and sybase, and we want to access the data which is resides in sybase
so i have some questions about oracle heterogeneous services for oracle 10GR2:
1. Is Oracle Transparent Gateways for free ??
2. where can I download the Oracle Transparent Gateways ??
3. where can I found the documentation ?

Heterogeneous Services with HTMLDB
Hi All,
I was wondering if HTMLDB exposes Heterogeneous Services connectivity to other datasources?
For example...if I create a DB Link to DB2 via a gateway is this information exposed in HTMLDB?Howard,
Nothing HTML DB-specific about your question. You might try this forum:Heterogeneous Connectivity

Heterogeneous Services ODBC to MS SQLSvr - ORA-00904 error
Hello, I have successfully setup a heterogeneous Services ODBC to MS SQLSvr using the steps outlined at http://www.orafusion.com/art_orahs.htm.
My problem is, the only queries that run without errors are SELECT * FROM tablename@xxx. When I try SELECT colname FROM tablename@xxx I get an ORA-00904: "colname": invalid identifier. Any thoughts?
Also, will I be able to update MS SQLSvr tables using this link?
Thanks.Hello, Your suggestion worked. Even though all the column_names are lower case, if I surrounded the column names with double quotes the query would work.
Another question. I'm wanting to update a SQLServer table with data from a Oracle table using a query like:
INSERT INTO sql_table@xxx
SELECT * FROM oracle_table ;
Is this possible? I'm getting a "ORA-02025: all tables in the SQL statement must be at the remote database" error message which looks like I can't.
Thanks. -
About Oracle Heterogeneous Services and Oracle Gateway
Hi All,
I am very new at this topic, I want to know:
1)Oracle Heterogeneous Services and Oracle Gateway same or not?Need license or not?
2)If want Creating Database Link from Oracle 11g to Sybase AS 15.5 Using Oracle Heterogeneous Services what drivers should I install from my pc(windows 7) and from my server(Linux red hat 5)?please give me link for this
3)Is there any link Step by step to configure odbc until creating dblink?
4)what more convenient, connect sybase from Oracle Heterogeneous Services or Oracle Gateway?
Thank you so much for your help
Regards
JOEJoe,
let copy/paste your questions and comment inline:
1)Oracle Heterogeneous Services and Oracle Gateway same or not?Need license or not?
Let me first clarify one thing, heterogeneous services is the generic mechanism in the Oracle database used by all gateways. The product you are talking about is the Database Gateway for ODBC or the Database Gateway for Sybase.
The Database Gateway for ODBC is available for Linux and Windows. It is the free product which does not require an Oracle license. The license is included in your database license. It is a generic gateway which allows you to connect with any suitable 3rd party ODBC driver to a matching foreign database. As it is a generic connectivity which aloows you to connect to real databases but also to MS Excel or even Text files as long as you have a suitable ODBC driver, its capability is very limited.
The more powerful gateway is the Database Gateway for Sybase. It covers the same functionality as DG4ODBC but it allows you also to work with distributed transactions, it allows you to call remote Sybase stored procedures etc. This gateway is design for Sybase ASE connections, so it is also able to map certain Oracle functions to Sybase equivalents. This Database Gateway for Sybase is NOT for free, it requires an additional license.
2)If want Creating Database Link from Oracle 11g to Sybase AS 15.5 Using Oracle Heterogeneous Services what drivers should I install from my pc(windows 7) and from my server(Linux red hat 5)?please give me link for this
That depends on your preferences. Both gateways are available for Linux and for Windows. When using DG4ODBC you only need to pay attention that you get a suitable 3rd party ODBC driver for this platform with the matching word size (64bit for 64bit DG4ODBC and 32bit ODBC driver for installations of DG4ODBC on 32bit platforms).
The latest software release is currently 11.2.0.3 and it can be downloaded (and installed from scratch) from "My Oracle Support". Just open the Patches & Updates section, look for Patch 10404530: 11.2.0.3.0 PATCH SET FOR ORACLE DATABASE SERVER and make sure to choose the platform you want to use. Then check out the readme as it lists which of these download CD's contains the gateway software.
BTW, the CD contains DG4ODBC and DG4SYBS and it is up to you to decide during the installation which product you want to use.
3)Is there any link Step by step to configure odbc until creating dblink?
The ODBC driver installation differs from vendor to vendor and platform to platform - so we don't have a specific note how to configure the ODBC driver. This kind of question is better handled by the ODBC driver vendor.
Regarding the set up of DG4ODBC on Windows you find suitable information in the knowledge base on My Oracle Support. Just look for:
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install [Document 466225.1]
and for DG4SYBS:
How to Configure DG4SYBS (Oracle Database Gateway for Sybase) on 64bit Unix (Linux, AIX, HP-UX Itanium and Solaris) Post Install [Document 437696.1]
How to Setup DG4SYBS (Database Gateway for Sybase) on a 64bit Windows [Document 1319852.1]
4)what more convenient, connect sybase from Oracle Heterogeneous Services or Oracle Gateway?
It really depends on your needs. DG4SYBS is surly easier to install as this gateway comes with everything you need and you do not have to find a suitable ODBC driver nor get the ODBC driver working. It is also more powerful as you can for example use triggers that replicate data changes in an Oracle database to the Sybase database within the same transaction. When you want to call Sybase stored procedures you can also do that with DG4SYBS. So it really depends on your needs.

Create Heterogeneous Services Initialization File
Hello, I am new to oracle as I am a student. I have installed Oracle Database 11g Release 2 Enterprise Edition.
I want to use a Microsoft Excel file as a source file. In the help center it says that I must create the Heterogeneous Services Initialization File in a specific directory using these commands: HS_FDS_CONNECT_INFO = odbc_excel
HS_AUTOREGISTER = TRUE
HS_DB_NAME = dg4odbc
My question is where should I run these commands ?
If I have to do it in SQL Plus, how do I go to the specific path? When SQL Plus opens it just writes SQL> and I dont know how I can go to the path I want to so I can run the commands.
I can go through the Command Prompt but it obviously doesn't recognize these commands.
Any answer would be enlightening. Thanks.http://docs.oracle.com/cd/E11882_01/owb.112/e10582/loading_ms_data.htm
You do not need to run the command from Sql*Plus
HS_FDS_CONNECT_INFO = odbc_excel
HS_AUTOREGISTER = TRUE
HS_DB_NAME = dg4odbc
You need to create initexcelsid.ora file in the OWB_HOME\hs\admin directory with the above listing -

ORA-02063: preceding line from MYSQL_LOCALHi,
The gateway file initMYSQL_LOCAL.ora should be placed in the directory -
$ORACLE_HOME\hs\admin
which is the expected location. In your setup this should be -
C:\app\product\11.2.0\dbhome_1\hs\admin
If the file is already in that location then make sure that in the listener.ora and tnsnames.ora that in each section every line except the first line starts with at least one space -
SID_LIST_LISTENER =
<space>(SID_LIST =
<space>(SID_DESC =
LISTENER =
<space>(DESCRIPTION_LIST =
Tnsnames.ora
MYSQL_LOCAL =
<space>(DESCRIPTION =
<space>(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
However, there is also a problem with the tnsnames.ora file. You have -
Tnsnames.ora
MYSQL_LOCAL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SID = MYSQL_LOCAL)
(HS = OK)
) <=== move this bracket
but it should be -
Tnsnames.ora
MYSQL_LOCAL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SID = MYSQL_LOCAL)
) <=== bracket moved here
(HS = OK)
Of course, with spaces as shown above. They are often lost in the forums.
You may also need to change -
(HOST = localhost)
to -
(HOST = <actual host name>)
but it depends on your setup.
Try these changes and let me know what happens.

Generic Heterogeneous Services
I’m trying to implement Heterogeneous Services using the generic
ODBC driver supplied with Oracle 8.1.7. I am attempting to
connect to a ForPro database running on a NT server from Solaris
5.7 running Oracle 8.1.7. Up to this point I have not been able
to properly configure the Listener so that it will run with the
non-Oracle listener information in the Listener.ora file. I get
an error (TNS-12545) “Connect failed because target host of
object does not exist”
Has anyone tried to connect to FoxPro on an NT server?
Were you able to do this with the generic ODBC driver supplied
by Oracle?
Can you post a copy of the relevant sections of the Listener.ora
and tnsnames.ora files?
If using an after-market ODBC driver, which one did you use?
Any help supplied will be greatly appreciated. I have very
little time to determine if it is possible to make this
connection and to get it working.I wouldn't think so these days ... however, you could try posting this in the heterogeneous services - which is somewhere on OTN.
If it we me, I'd convert the DBF into something easier to use with Oracle : like XML or CSV -
Heterogenous Services in 8.1.7?
Does anyone know if the Heterogenous services (database links through ODBC) are available in the 8.1.7 release for Linux. The readme didn't say it wasn't like it did for 8.1.6. If it is there, has anyone gotten it to work?
Have u got the replaction manager wizard on 8.1.7 - the same problem i am also facing i f u have any solution to find it out please send me.
And one more thing have u ever configured replication successfully - If yes please send me steps in short. as I am unable to configure it.
Regds,
Amit.
<BLOCKQUOTE><font size="1" face="Verdana, Arial, Helvetica">quote:</font><HR>Originally posted by Jeremy Perkins ([email protected]):
What happened to Replication Manager in 8.1.7?
Does it only exist as part of the DBA Studios package?
I have tried using this but have found one major flaw. When using a replication administrator user for handing replication, I cannot specify the Tablespace to replicate objects to. All the other storage parameters are available except TABLESPACE.
Has anyone else experienced this problem?<HR></BLOCKQUOTE>

JawadDear Anwar,
I'm using XPSP2 10gR2Enterprise
SID=ORCL
host=andor (my PC's name)
Pls help me. I'm struggling with HS also so I've followed your lines, meaning:
I can create the database link, but cannot retrieve data from source. (see 7.)
1a. I have created the Excel file c:\EXCL.xls
NEV DATUM BOOL NUMBER
Stefán Balázs 09.nov TRUE 0
Sebestyén Dénes 10.nov TRUE -11
Tóth Andor 11.nov FALSE 12.3
c: is partition on the same server where 10g sits.
1b. I've created an ODBC system DSN for this excel file, named EXCL.
2. tnsnames.ora has bee nupdated by this:
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = andor)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
EXTPROC_CONNECTION_DATA =

(PRESENTATION = RO)
EXCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = andor)(PORT = 1521))
(CONNECT_DATA =

(HS = OK)
3. listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)

4. initexcl.ora in hs directory:
HS_FDS_CONNECT_INFO = EXCL
HS_FDS_TRACE_LEVEL = 0
Listener restarted.
5. in iSQLPlus:
SQL> CREATE DATABASE LINK excl USING 'excl';
Database link created.
6. in Enterprise Manager there is a Database Link:
database links: EXCL.REGRESS.RDBMS.DEV.US.ORACLE.COM
service name: excl
7. testing the database link says:
The Database Link is not active.
ORA-28545: .Unable to retrieve text of NETWORK/NCR message 65535... ORA-02063: previous 2 lines from EXCL
Please help me to get over this. -
Help with heterogeneous services
Hello.
I have been asked to try to create a dblink from an oracle 9.2 database on a solaris machine to a mysql 5.1 database on a windows xp machine.
I need to know what software I need to get and install on both machines and what settings on the oracle server are needed.
I just hope that someone who has done this before can help me.
Thanks in advance.Hi,
If you are looking for a tutorial sort of thing for Heterogenous Services than this thread over Asktom is a good resource. Look inside it an example given by Tak Tang for connecting Oracle Database with MS Excel. Take it as a reference to do your work.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:4406709207206
And for the Heterogenous Services, look at the doc guide of it here,

Heterogeneous Services & SQL Server
I understand that connecting an Oracle database to a SQL Server database can be done using the Heterogeneous Services which will set up a Transparent Gateway to the SQL Server data. Where can I get the agent needed to connect the two though? Are there different agents for different Oracle/SQL Server version combinations?
I have the paper 'Oracle8 Distributed Database Systems Release 8.0 A58247-01, Chapter 7: Administering Oracle Heterogeneous Services', and it is very helpful in getting the basics, but I need more info for my particular situation. Supposedly the agent has an Installationand User's Guide which would assist me also.Do you have any pending statements in dba 2pc pending?
Your init parameters seems good. you need to check with the network guys for the packages sent from Oracle is received by sql server and vice versa. Hope there is no block on redirect ports.
You can enable tracing and see if you get any valid points in this direction.
As you said about trigger, look for the privileges in sql server does the user you are connecting has all the privilege on the associated tables. Also the conditions on the trigger has to be satisfied for the execution.
Also you need to add some HS parameters for the recovery in case you may need. -
Heterogeneous Services through ODBC
There has been some different remarks about if Heterogeneous Services through ODBC will be available in XE. So now when we are getting close to the production release of XE I want to know what the final answer is on this feature
For the sake of future readers: This works! I just paraphrased this approach to successfully create a dblink to my Sql Server 2000 EE running on MS W2K Svr. It took some time to sort out the details, and then to discover that the test in Tak Tang's excellent writeup did not work for me. I could not do: select table_name from all_tables@mydblink; without getting:
ORA-00604: error occurred at recursive SQL level 1
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC]
ORA-02063: preceding 2 lines from DBLINK_IMS
However, when I finally woke up and tried: SELECT * FROM <MySmallTable>; I realized that it was actually working.
I hope this hint is helpful to future readers. Many thanks to TTang for his excellent writeup. Thanks also to Oracle for an excellent product. -

Heterogeneous Services & Oracle Generic Connectivity For DBF file?
Dear All,
Can We Create dbf file directly means without using CSV file?
Can we use Heterogeneous Services & Oracle Generic Connectivity for creating dbase DBF file or Writing in dbase DBF file?
I have used it for Excel and Access for connectivity with Oracle 9i
but I dont have any idea about dbase DBF file?
Any help in this reagards will be highly appriciatalble.
Thanks
RanaHSODBC/DG4ODBC is generic connectivity and you find the generic setup in:
Note.109730.1 How to setup generic connectivity (HSODBC) for 32 bit Windows (Windows NT, Windows 2000, Windows XP, Windows 2003)
There is nothing sepcial for DBF's. Just define a system ODBC DSN using a DBASE ODBC driver pointing to the DBF file.
The rest is absolute similar to the note.
If you have already a running HSODBC/DG4ODBC the quickest test is to just define a new system dsn for the DBF file, then change in the init>hsodbc/dg4odbc>.ora file the HS_FDS_CONNECT_INFO parameter pointing to the newly created system DSN. Last step is within the Oracle db to define a database link.
