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 + Excel ODBC Driver ???...Urgent PLEASE...

Hai all,
I like to use HS+ excel Odbc driver to load data from excel file to owb. I do all the steps correctly. I created a mapping. While deploying the mapping I got the following error.
"error occurred when looking up remote object <unspecified>.EmployeeRange@EXCEL_SID.US.ORACLE.COM@DEST_LOCATION_EXCEL_SOURCE_LOC
ORA-00604: error occurred at recursive SQL level 1
ORA-02019: connection description for remote database not found
Could you please help me... its very urgent for my application....
Thanks and regards
Gowtham

SUDHAKAR,
If you use Oracle Generic Connectivity you can access any ODBC or OLE DB compliant data source including Excel. You will also have to have the ODBC or OLE DB driver on the Excel side. For further information, please take a look at:

Oracle Heterogenous Services using JDBC (not using ODBC)

Dear Friends,
I need to configure Oracle HS to connect with MS SQL Server using JDBC as our company don't want to go for ODBC connection.
Operating System is HP-UX
Oracle Database Version is
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for HPUX: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
Can anyone please help me.

The options you have for Heterogeneous Services are ODBC and OleDB.
JDBC is not an option.
The only other option is Transparant Gateway, a separately licenseable product.
I don't know whether Transparant Gateway relies on other drivers.
From the Sqlserver end there is MSDTC.
Oracle generally doesn't underdocument their products.
You can safely assume if it isn't documented, it isn't there.

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.

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,

Connect PostgreSQL to Oracle 10g through ODBC: can't read all_tables

Oracle 10g is not able to read the database table names (all_tables and all_objects, es. select * from all_tables@hspostgresodbc) from PostgreSQL using ODBC (v. 08.01.0200). This functionality is essential to be able to use Oracle Warehouse Builder and import external database definitions (heterogeneous services).
However, Oracle (SQL*Plus) is able to retrieve records when the table name is stated in the SQL query (es. select * from my_table).
The problem seems to be specifically with the PostgreSQL ODBC because Oracle is able to read schemes from other databases through ODBC. Ive done some tests with Access dbs just to be sure that the problem is not with my system (Windows XP SP2).
The problem appears both with ANSI and UNICODE PostgreSQL drivers.
Any suggestion of how workaround this problem?
thanks in advance,
Raoni

Dear all,
Ive tried different tracing levels with out success. The log file does not seem to be created by Oracle.
Looking closer to the debug and comm logs from the driver 8.01.0200, Ive found out that the problem was generated after a table wasnt found (the driver seems to search for the all_tables table, and just afterwards to query the scheme pg_catalog). In this case the all the following queries returned with the error ERROR: current transaction is aborted, commands ignored until end of transaction block. Maybe this problem is related with the bug [#1000641] http://pgfoundry.org/tracker/index.php?func=detail&aid=1000641&group_id=1000125&atid=538
Following the Postgres odbc developers suggestion, Ive installed the psqlODBC v 08.02.0002 and Ive got a completely different result.
As before, the simple query select * from my_table@hsodbc returns the result using SQL*Plus clearly faster than before.
Doing the query select * from all_tables@hsodbc the result is OK (the name of 56 tables) but the process is very slow and burdensome. The file paging memory in the machine running Oracle and the SQL*Plus jumps from the normal 700 MB to 1.7 GB, and the query takes about 20 minutes to complete.
Also the 1.7 GB remains allocated and the query process halted in PostGreSQL even after the on screen result of the query. The memory is freed and the process terminated after the logging out SQL*Plus.
Probably as result of this memory explosion, the system runs out of memory and Oracle Warehouse Builder selecting data base link -> schema, after some minutes get an error similar to: cant read from memory address XXXXX
All those test where done with PostGreSQL 8.0.1 (on Linux Suse 9.0) and Oracle 10g (Windows XP SP2).
To be sure that the problem was not related to the PostGreSQL version, we updated the server to the 8.1.3 (running in Linux Suse 9.0 with psqlODBC v 08.02.0002 ) and OWB couldnt see any table as before and doing Select * from all_tables@hsodbc weve got the message:
ERROR:
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 HSPG
no rows selected
On the other hand, with the same configuration as before (Oracle 10g under Windows XP SP1, psqlODBC v 08.02.0002) but with PostGreSQL 8.1.3 under Windows XP SP1, OWB can read table names (same tables imported from Linux PostgreSQL) but not all_tables (a minor problem, because what is important for us is to make OWB work with PostgreSQL).
The encoding for all DBs is UTF8.
Any ideas of where could be the problem?
regards,
R.

Hi,
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.
Regards,
Mike

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

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.

Heterogenous connectivity - HS ODBC

Hi,
what are the licensing constraints for such a product? Does it work with standard version or requires it Enterprise Edition, or is it a package to be bought separately?
Thanks
Ciao

Specifically on the licensing question
Heterogeneous Services is included with your database license
In order to actually make a database link to a non-Oracle database, though, Heterogeneous Services needs either Generic Connectivity or a Transparent Gateway. Generic Connectivity appears to be what you are looking to use-- that uses ODBC or OLE DB drivers to make a generic connection to the non-Oracle database. Generic Connectivity is included with your license, though you would potentially have to license the ODBC/ OLE DB driver. Using a Transparent Gateway, on the other hand, provides additional functionality (such as two-phase commits and additional performance), but requires licensing a separate Oracle product (the Transparent Gateway).
And just to note, nothing I've written here is in any way binding on Oracle-- only your Oracle sales rep can make that sort of binding agreement. My comments are general licensing comments-- your organization may have an agreement with Oracle that changes some or all of the standard licensing terms. Licensing terms may differ in your country. Oracle may change licensing terms whenever it wishes. And should there ever be a question about whether you are properly licensed, relying on comments made by some guy on the internet with a playing card logo next to his name probably isn't the position you'd want to be in.

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

HSODBC/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.

Using Oracle Heterogenous services to access sql server database table

I have created a dblink 'POC_HS' from oracle to sql (implemented heterogeneous services) and I am able to successfully pull out data from the default database that the DSN(for sql server) is connected to.
So this 'select * from Test@POC_HS' is working perfectly fine on the Oracle database as 'Test' table resides in the default database (which the System DSN is connected to).
But when I do 'select * Abc.Test@POC_HS' where Test table resides in 'ABC' database which is not the default database throws an error as follows:
ORA-00942: table or view does not exist [Generic Connectivity Using ODBC][Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 'Abc.Test'.[Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared. (SQL State: S0002; SQL Code: 208)
I have also tried this 'select * from Abc.dbo.Test@POC_HS' but oracle throws this exception "ORA-00933: SQL command not properly ended".
The dblink user and System DSN account has access to the 'Abc' database.
Thoughts?

Thanks for the info.
But suppose if we have DB link 'POC_HS' where POC_HS is a DBlink between oracle servers, I can do the following -
1. select * Abc.Test@POC_HS
2. select * Def.Test@POC_HS
where Abc,Def are the schemas which the Dblink user has access to. I can execute the above perfectly fine.
I wanted the achieve the same functionality from Oracle to Sql where database keep on changing dynamically . So according to you that's not possible right?
We will have to keep on changing the ODBC connection to a different database or create a new odbc/listener/tnsentry each time query uses a different database right?
