Generic connection to oracle

Hi !
I heard about a generic connection to oracle (with OCI ??). The user x connects himself to the serveur with a generic login and password. Then he's connected as "user x".
I'd like to know how does it work, and if it is possible to do audit trail with this type of connection.
Thanks.

Use HS Generic Connectivity in Oracle Express (XE)

Can I use HS Generic Connectivity in Oracle Express (XE) or do I need a "full" database?

I see you've managed to get HS working on Oracle XE. I am trying to do the same, but am hitting a wall when trying to set the hs_fds_connect_info parameter in that Oracle does not seem to recognise it:-
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production
ORA-32003: error occured processing parameter 'hs_fds_connect_info'
LRM-00101: unknown parameter name 'hs_fds_connect_info'

hs_autoregister boolean TRUE
Is there anything I need to set elsewhere to enable this? Any help would be appreciated.

Oracle Generic Connectivity in Oracle Application Ser ver 10g.

Hi Tak and All!
With the help of your great guidence, I have connect the Generic Connectivty for MS Access and MS Excel successfully in client server environment.
The topology was..
Host A = Custom installation of Oracle9i database + MS ACCESS
Host B = Oracle 9i Database (Complete)
But...
tell me How the Oracle Generic Connectivity will connect in ORACLE APPLICATION SERVER. What will be the concept and topology? Because the client only have the URL which is used for getting application on browser.
I will be extremely thankful.
All these forums always help me.
Thanks
Rana Adnan

It depends. Oracle Reports can connect to Oracle and non-Oracle databases directly, without using Generic Connectivity.
Your Forms application would presumably connect only to the Oracle database. The Oracle database might well connect to other Oracle and non-Oracle databases via database links. The non-Oracle database links would utilize Generic Connectivity.
Given the three machines A, B, and C
A could connect to B and B could connect to C
A could connect to C for reporting queries

Generic Connectivity from Oracle 10gR2 to SQL Server using ODBC

Hi,
I have setup an ODBC generic connection from an Oracle 10.2 database (on Win 2000) to a SQL Server database (on a different Windows machine). When I query a column which is of LONG data type (TEXT on SQL Server) my session just hangs, no data or errors are returned, trace file just ends showing the SQL statement I entered, but no errors.
If I query other columns with CHAR, DATE, NUMBER datatypes the rows are returned successfully. As far as I can see from the documentation, the TEXT data type in SQL Server should map to SQL_LONGVARCHAR in ODBC, then that should map to LONG in Oracle, so I wouldnt have thought it was an incompatible data mapping issue.
I hear that LONG is being replaced/deprecated in Oracle, but is it now not supported by the HS ODBC program provided with 10g Rel 2? Has anyone else had a similar problem and found a workaround? Any help is much appreciated.
Kieren.

Hi,
HSODBC is not supported on Windows x64. So that's why you get the error ORA-28545
What you can do is to install DG4ODBC 11g on a 32bit machine.
DG4ODBC can be installed separately from the Oracle Server, for example on the SQL SERVER if you can.
But it is supported only in 32 bit too.
You can download from this website:
http://www.oracle.com/technology/software/products/database/oracle11g/111060_win32soft.html
==>Oracle Database Gateways 11g Release 1 (11.1.0.6.0) for Microsoft Windows (32-bit)
The last option would be to create a virtual machine on your X64 machine with a Windows 32bit and DG4ODBC 11g.
Please let me know if you have any question.

Mireille

How to do a Generic Connectivity (ODBC) ?

Hello,
Generic Connectivity provide Oracle Database to connect another
database via ODBC. In my case, it is Oracle 8.1.6 which connects
to Sybase Enterprise 11 on Win NT. The Module "Generic
Connection" is installed. I view it by the Oracle Universal
Installer and I have configured the Windows ODBC Manager to
connect to Sybase.
This is what I've done step by step:
1. C:\Oracle\Ora81\hs\Admin\iniths_syb.ora
HS_FDS_CONNECT_INFO = SPS_NACIONAL
HS_FDS_TRACE_LEVEL = ON
HS_FDS_TRACE_FILE_NAME = hs_syb.log
2. C:\Oracle\Ora81\Network\Admin\Listener.ora
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = nacional)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = oracle)
(ORACLE_HOME = c:\Oracle\Ora81)
(SID_NAME = oracle)
(SID_DESC =
(SID_NAME = hs_syb)
(ORACLE_HOME = c:\Oracle\Ora81)
(PROGRAM = hs_syb)
I reload the listener by the following command :
lsnrctl
stop
start
3. C:\Oracle\Ora81\Network\Admin\Tnsname.ora
ORACLE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = host)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = oracle)
hs_syb =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = host)(PORT = 1521))
(CONNECT_DATA =
(SID=hs_syb)
(HS = OK)
I test the tnsname at the prompt command line :
tnsping hs_syb
(It's OK)
4. Database Link
CREATE PUBLIC DATABASE LINK syb
USING 'hs_syb';
5. Test database link
select * from emp@syb;
And Errors occur :
ORA-28509: unable to establish a connection to non-Oracle system
ORA-02063: preceding line from SYB
6. I read again the documentation
http://technet.oracle.com/doc/oracle8i_816/server.816/a76960/hs_g
enco.htm
and I found some tables to be feed with data by the HS_ADMIN
packtage :
This is what I have added :
EXEC DBMS_HS.CREATE_FDS_CLASS ('hs_syb','Uses ODBC Driver')
EXEC DBMS_HS.CREATE_FDS_INST ('hs_syb','hs_syb','SYC Sybase
System 10/11')
EXEC DBMS_HS.CREATE_INST_INIT
('hs_syb','hs_syb','HS_DB_NAME','SYBDATA','F')
(Drop procedure :
EXEC DBMS_HS.DROP_INST_INIT
('hs_syb','hs_syb','HS_FDS_CONNECT_INFO')
EXEC DBMS_HS.DROP_FDS_INST ('hs_syb','hs_syb')
EXEC DBMS_HS.DROP_FDS_CLASS ('hs_syb');
I test one more time the connection,
And I have the same error message as step 5.
7. I put in the initialization file (initoracle.ora) the
parameter
Hs_Autoregister = true (It is true by default and it doesn't
change errors. Is it another parameters for HS ?)
In fact, I don't really understand the notion of "AGENT" for HS
(Heterogeneous Services) in Oracle. Is it something to enable or
is it automatic because the iniths_syb.ora file is in the path
ORACLE_HOME\hs\admin ???
What is it missing for the Generic Connectivity ? Any
suggestion ? Say me what is the wrong step in this process or
what I have forgotten.
Thank you in advance.

Hello
You're right, step two needs to set (PROGRAM = hsodbc). I understand this when I saw hsodbc.exe in the path ORACLE_HOME\Bin (and at prompt I try agtctl.exe but without sucess, an utility for Heterogeneous Services).
Now when I test the connection I can hear Oracle running something.
This is what I've done step by step (following my previous message)I test with Sybase Entreprise and Sybase Anywhere :
8. C:\Oracle\Ora81\Database\initoracle.ora
I set a parameter in init file and I reload Oracle database :
global_names = false
OR in SQL+
alter session set global_names=false;
WITH SYBASE ENTREPRISE
9. C:\Oracle\Ora81\hs\Admin\iniths_syb.ora
At the beginning my iniths_syb.ora file was wrong then I correct parameters by viewing errors in C:\Oracle\Ora81\hs\trace :
#Using a dsn file generate by the Windows ODBC Manager
HS_FDS_CONNECT_INFO="FILEDSN=C:\sybase.dsn"
HS_FDS_TRACE_LEVEL = ON

set SYBASE=C:\\Sybase\\ASE
Contents of sybase.dsn

DRIVER=Sybase System 11
UID=USERNAME

10. Test Database link

ORA-00942: table or view does not exist

Contents of anywhere.dsn
[ODBC]
DRIVER=Adaptive Server Anywhere 6.0
UID=USERNAME

12. Test Database link
CREATE PUBLIC DATABASE LINK anywhere
CONNECT TO USERNAME IDENTIFIED BY SECRET
USING 'hs_any';
select * from anytable@anywhere;
In SYBASE ANYWHERE I've got this data
select * from anytable
go
dateini col1 col2
2002-02-01 00:00:00.0000 1.5000 1.4000
In ORACLE I've got
SQL> select * from anytable@anywhere;
dateini col1 col2
01/02/02 1 1
There isn't the decimal.
The reason doesn't like to be 1.4 or 1,4 because in Anywhere and in Oracle It is the same insert "insert into anytable values ('02/02/01', 1.5, 1.4)".
13. Now I try a select of one column
select col1 from anytable@anywhere;
this error occur :
ORA-00904 invalid column name
I am sure that this column exist ! "select * from anytable@anywhere;" and "select count(*) from anytable@anywhere;" are OK.
14. And this doesn't work anymore :
insert into bx_surcharge@anywhere values ('01/02/02',1,2);
ORA-02047: cannot join the distributed transaction in progress
15. Step 6 and 7 doesn't mean to be necessary ? And Where are used parameters of the "ODBC Connectivity Requirements" in the documentation. http://technet.oracle.com/doc/oracle8i_816/server.816/a76960/hs_genco.htm (And How to use Datatype Mapping ?)
So How to successful a ODBC connection (Maybe I forget some parameters) ? For me, using a connection with ODBC is generic and have to work fine with any type of datasource, isn't it ?
Have you got any idea to deal ? Thanks a lot.

Using Oracle Generic Connectivity to connect from Oracle to Microsoft Acces

I am trying to connect from Oracle to Access using ODBC. I followed the steps described in oracle documentation but was not sucessful. Could you plase take a look at my code let me know where I went wrong. It is as follows :
1)Created an ODBC connection for Microsoft Access called 'MSACCESS' (System DSN). And associated accdb1.mdb to this ODBC connection.
2)Created a table called orders in accdb1.mdb.
3)Added the foll lines in tnsnames.ora
accdb1 =
(DESCRIPTION=
(ADDRESS=
               (PROTOCOL=tcp)
               (HOST=kdandapani.170systems.com)
               (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=accdb1)
(HS=OK)
4)added the following lines in listner.ora :
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME=accdb1)
(ORACLE_HOME=c:\orasrv)
(PROGRAM=accdb1)
5) Copied inithsodbc.ora to iniths_accdb1.ora in the ORACLE_HOME/hs/admin directory. Added the following line there :
HS_FDS_CONNECT_INFO = MSACCESS
6)Created the foll dblink :
create database link access1
using 'accdb1';
7)tried to access table ORDERS in the MSACCESS database with the foll SQL -
select * from orders@access1;
Resulted in the foll error message
ERROR at line 1:

Following are the steps you suggested in this forum :
1)Created an ODBC connection for Microsoft Access called 'MSACCESS'. And associated accdb1.mdb to this ODBC connection.
2)Created a table called ORDERS in accdb1.mdb.
3)Added the foll lines in tnsnames.ora

(ORACLE_HOME = c:\orasrv)
(SID_DESC =
(PROGRAM = hsodbc)
(SID_NAME = MSACCESS)
(ORACLE_HOME = c:\orasrv)
5) Copied inithsodbc.ora to iniths_MSACCESS.ora in the ORACLE_HOME/hs/admin directory. Added the following line there :
HS_FDS_CONNECT_INFO = MSACCESS
6)Created the foll dblink :
create database link MSACCESS
using 'MSACCESS';
7)tried to access table ORDERS in the MSACCESS database with the foll SQL -
select * from orders@MSACCESS;
I have used my login table instead of orders. But i got an error that i have stated earlier.
Can you please help me ? if possible than please forward your reply to : [email protected]

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
Rana

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.

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

How do I start on Oracle Generic Connectivity?

Hi, I am new to Oracle and can i know where i can get info on setting up Oracle Generic Connectivity to connect Oracle with non-Oracle databases?

The documentation is a good place to start. The relevant

MS drivers for Oracle was designed a very long time ago with Oracle7 in mind.
You might want to see: http://support.microsoft.com/kb/244661
I have not tested your code, but I guess you need to consider giving up on the idea of using ancient interfaces such as Jet. Not sure about MS' supporting the technology, but at least the older "win 95" versions seem unlikely to be Unicode-enabled.

Error connecting to Oracle on Red Hat 7.2 with WL 7.0

I able not able to connect to Oracle on Red Hat 7.2. I have tried both 9.0.1 and 9.2.0.
I am able to use a very similar configuration and W2k and it works.
Here is the situation:
I have installed Weblogic 7.0.0.1 on Redhat 7.2. It works fine in generic form.
I have also installed Oracle 9.2.0 client files. I have verified connectivity with
a remote database using the Oracle tnsping tool. I have modified the startWLS.sh
file so that the oci901_8 libraries are used by Weblogic. I have added the following
line to startWeblogic.sh:

Hi David,
The driver for 9.2.0 is not yet out. You may want to use the thin driver.
You can also request this driver by filling a support case.

These are same values I used for the tnsping which does work.
Any other ideas?

Generic connectivity to SQL server: what kind of performance can I expect?

I have set up a generic connection to a SQL server 2k db, with Oracle on another win 2k box. Both databases are in their "out of the box" configuration, so no particular tuning has been done: but the generic connectivity shows awful performance. In fact I have tried various kind of queries, and all of them show abysmal performance. A query with an "insert - select" that transferred 80K lines executed for one hour, with an average transfer rate of 1KB per second!
I don't think this is the kind of performance I can expect from this tool, is it? Is there anyway particular I can do in order to tune the dblink over the generic connectivity?

I don't think this is the kind of performance I can
expect from this tool, is it? Is there anyway
particular I can do in order to tune the dblink over
the generic connectivity?Nevermind: apparently there are network communication problems between the two machines. Trying to execute the same tests on two co-located dbs shows performances of about 700ms in order to transfer 70000 3-column lines from a sql server db to oracle with a "insert into ... select * from" query.

There is a typo in the name of you gateway init file. You posted the content of inithMYSQL.ora but the naming is init<SID>.ora which is in your case initMYSQL.ora.
In addition please keep in mind HSODBC has been desupported since 2008 and when starting a new configuration you should use the follow up product dg4odbc (Database Gateway for ODBC) V11.

How to connect to Oracle 11g using thin driver with service name & SID

Hi Experts,
Wish to know whether there is a common way to connect to Oracle 11g server using SID or service name.
Earlier I used jdbc:oracle:thin:@<<server>:<<port>>:<<SID>> for connecting to individual Oracle server instances.
Now I need to connect to Oracle RAC which provides service names. So I need to use jdbc:oracle:thin:@<<server>:<<port>>/<<service name>>.
This connection string is internally constructed by a program and user inputs <<server>>, <<port>> and <<SID>> or <<Service Name>>. Now this requires two different connection strings based on the input whether its SID or service name.
Is there a common connection string for these two? Based on some articles like this, I understood that we can generically use jdbc:oracle:thin:@<<server>:<<port>>/<<service>>, whether for SID and service.
When I tried this format with SID, I am getting the below error. What I tried is jdbc:oracle:thin:@myoracleserver:1521/ORCL, where ORCL is the SID
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
Request your help in solving this. What I want is a single connection string whether its SID or service. Any help is of great value.
Regards
Sunil

Oracle has an entire book for JDBC: The JDBC Developer Guide.
There are chapters that provide ALL of the connection properties and the rules for creating connection urls.
