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

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.

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
link:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96544/gencon.htm#1656
For supplementary material do a google search on

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'
SQL> show parameter hs
NAME TYPE VALUE
hs_autoregister boolean TRUE
Is there anything I need to set elsewhere to enable this? Any help would be appreciated.

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.

Howmany oracle user connect with oracle server.

hi all
howmany oracle user connect with oracle server.
i want query for above sentance.

Robert,
This query will show us the username who are connect to a particular database. If OP wants that how many overall users are connected to his/her oracle server (which is having more than one db) then please tell us. Suppose 10 users are connected with db1 and 20 users are connected with db2.. like that.

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:
ORA-12154: TNS:could not resolve service name

hi,
I am new to Generic Connectivity i have just followed all the steps you wrote once in this forum but i m getting the following error :

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
MSACCESS.170SYSTEMS.COM =

(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = kdandapani.170systems.com)(PORT = 1521))
(CONNECT_DATA =

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]

[Pro*C] Multiple Oracle Db connections in single application

Hi,
I'm using Pro*c for developing an application that makes use of two different user accounts, both connecting to a single local database.
I'm wondering what would be the best practice to handle both connections in my application.
Others DB engines might use "EXEC SQL [n]..." where n is the "context" or "connection identifier" provided that "EXEC SQL 2 CONNECT ..." and "EXEC SQL CONNECT " were previously executed. This makes it easy. In Oracle, things look like a little bit tricky.
Shall I be using Oracle's contexts, aren't they reserved for multithreading ? I found "CONNECT AT ...." but not sure what :db_string I shall use.
Is there another (easy) way ?
If so, a short code sample or web link would be appreciated.
Thank you !
SC

The max capacity for a data source is per node in the cluster (if it's targeted to the cluster).
So if you have 3 data sources, with max capacity of 20 each and two nodes in your cluster you should have around 3*20*2 = 120 connections.
Of course at startup WebLogic only creates the number of connections specified in the initial capacity.

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

Hi Kim and ALL!!!!
1)for Access this works perfectly and insert the data in class@dlcollege.
when_button_pressed triggerDECLARE
     X NUMBER;
BEGIN
     FOR X IN (SELECT tno, tname FROM TEST)
     LOOP
          INSERT INTO CLASS@DLCOLLEGE

Can Oracle 7i and 8i be connected from Oracle 9i database

I want to know if i can do the following. That means is it possible in production scenario. If yes then how and will it affect the performance to a great extend.
We are now upgrading the application server to weblogic 10.3 . But this server supports only Oracle 9i and above. But we have two more data server which are Oracle 8i and Oracle 7i. These databases will be upgraded later on but not now. So the problem is i can not connect to these Oracle database versions if i use Weblogic 10.3. So i wanted to know if there is any possibility of connecting the application server to a intermideate Oracle 9i database which will act as a bridge from Application server to Oracle 7i and 8i. Can Oracle 9i connect to Oracle 7i and 8i. If yes then how. You can provide me online references if any.
Thanks in advance. Waiting for your reply.

But i want to connect from Oracle 9i to Oracle 8iWhen connecting from one db to another (via a db_link) the 'calling' db is just another client to the 'called' db. if you can connect to 7.x (there was no 7i) with a 9.x sqlplus, then you should be able to connect with a 9.x database. At a previous job, we did something similar to get an app compiled against 8.1 to use a 10.2 database - set up a 9.2 intermediary that had nothing but db_links and synonyms pointing on to the 10g.
However, I wouldn't bet the company on making your scenario work. You really should upgrade your databases first.

Driver problem to connect the oracle database

sir
i want to use oracle 8.0 database at the backend in my project
i want that it is platform indpendent but
so i access that it is achive when i am not use the odbc driver
In xp the oracle not connect with my application
and in win98 some time it is connected to the application by
the odbc driver.
can it is possible that i use oracle database with out use of ODBC bridge in all Microsoft opertaing system types that is win 98,2000,XP
and NT
if yes how please help me and where i found the driver for oracle
with no price.
also how can i made the connection with my application.
thanks in advance

First:
post this in the approriate forum. This is for Swing questions, not for database driver questions. You have more luck in the JDBC forum, but still this isn't really a Java/JDBC question.
Second:
try to use the search before posting a question. Questions regarding the ODBC bridge are posted about 5 times a day (in the JDBC forum)!
Third:
to answer your question: download the Type 4 JDBC driver from otn.oracle.com. You can use it with every JDK on every platform.

Unable to use Cache connect to oracle

Hi Friends,
I am using TimesTen Cache connect to oracle to connect to Oracle 9i. When I tried to
Command> call ttCacheUidPwdSet('testuser','mypsswrd'); it gave me an error saying
"con1: Command> call ttCacheUidPwdSet('TestUser', 'prashant');
Warning 5105: OCI initialization failed: Error due to failure of ttOCIEnvNlsCre
ate (called from ttBDbEnvAlloc/ttBDbInit).
Warning 5109: Cache Connect general error: BDB connections not open."
can anybody tell me what could be the problem.
And to use cache connect is there a separate installation ? or setting ?
Thanks,
Prashant

What exact version of Oracle client is installed on the TimesTen machine? Are the permissions for the Oracle client directory and files set correctly? Do you have your Oracle environment properly setup (i.e. can you connect to Oracle using SQL*PLUS)? When you installed TimesTen, did the user you used to install it have a valid Oracle environment?
This type of error is almost always due to an unsupported version of the client or an incorrect environment either at runtime or at installation time.
