How to connect to oracle database from visual basic 2010 express edition

I have installed visual basic 2010 express edition on windows xp. But visual basic 2010 express edition supports Microsoft sql server database file,Microsoft sql server compact 3.5, Microsoft access database file. I want to connect to oracle database from visual basic 2010 express edition. So what drivers are required and how to do connectivity?

Hello,
I wasn't clear on what you were using to make the connection. I had a look in Visual Studio 2010 (don't have express to test sorry).
I think you mean the Data Sources available under the menu Data-> Datasources. this seems to match the description you give when I
look at the list of datasource options.
In here you can make ODBC connections via the Microsoft .net Data Provider .
If you select ODBC as a datasource you can see listed the DSN's you created - for example I see 2 which use the Oracle ODBC driver.
This assumes you installed an Oracle Client + the oracle version of the ODBC driver (comes with the oracle client).
Once you created a server connection then you should see it in the server explorer.
You can also download the Oracle Developer Tools for Visual Studio which is an add on for VS.
** I suspect this is only for VS 2010 and I didn't see that Express was supported.

Let me know if that helps.

How to connect Oracle database into Visual basic 6.0

Hi. I am using Oracle I Enterprise version 9.2.0.1, I have a problem for connecting oracle database into VB. I use a ODBC to connect oracle database with VB. By testing connection. Message tells me that "connection successfully", but I can not have a record display in VB. It tells me that can not publish a connection with ODBC. Please tell me why

Are you using the Oracle ODBC driver? If so, which version?
Are you writing your own VB application? What API are you using-- ADO? Can you post the code that's making a connection and the exact text of the error message?

How to install Oracle Label Security in Oracle Database 10g EE

Hello All
I just want to know how to install Oracle Label Security in Oracle 10g Database EE.
I read in Oracle Enterprise Manager Grid Control Installation and Basic Configuration that Label Security must be installed before installing Enterprise Manager Grid Control.
I have Oracle Database 10g Release 1 (10.1.0.1) on my Windows XP System, and I patch it to 10.1.0.3.
M.
Sorry about my English.

Options is to connect to Oracle Policy Manager or use Oracle Internet Directory (OID)to administer Oracle Label Security.
Find more ways in the Documentation here:

How to configure Oracle database in a failover zone cluster

Setup: Oracle database and zone configured on highly available local filesystems.
Two node cluster.
Oracle database running inside the zone.
Note: I dont have a zone cluster.
1. I need to make the zone and the oracle database highly available.
2. Can I configure the Oracle Data service directly to run in the zone or will it involve creating sczsh_config script to do the same.
I have been going through the guides and searching over the net, but haven't found any help so far. Its so much simpler to configure this environment in Veritas cluster. Hope I find some help here.
TIA,
Sudhir

The Oracle Solaris Cluster concepts guide has some information on which zone model to choose:
http://docs.oracle.com/cd/E18728_01/html/821-2682/gcbkf.html#scrolltoc
When managing a Solaris zone with the HA Zones agent, the cluster basically regards the non-global zone as a blackbox.
As such you can either start the Oracle database as part of the runlevel/SMF startup of the non-global zone, or you can use the sczsh or sczsmf component and use your own scripts to start, probe and stop the Oracle database.
Usage of the standard HA Oracle data service is not supported in combination with the HA Zones agent.
If you require a more fine grained control of services running in non-global zones, why not setup a zone cluster and then having HA Oracle failover the Oracle database between non-global zones?

Using AE(htmldb 2.0) as for reporting tool for other oracle databases.

Maybe I was mistaken, but when I first saw the HTMLDB demo's I saw this as a slick way to build a browser based reporting tool for the masses for quasi-ad-hoc reporting on some of our larger databases that currently have limited reporting capability, and also as a possible replacement for the many MSAccess applets we have.
I just got 2.0 installed and working on a 9i database and went through the basic tutorials, but I can't find much info on how to connect to other oracle databases.
Are my options as follows?:
create dblinks from the local database that houses htmldb to all the other databases?
or
install htmldb schemas on each database I want to access from htmldb?
or
I'll keep looking, but if any of you have any pointers or know of a tutorial that explains the best way to do this it would be greatly appreciated!
tia

As for question 1, yep, that's what I mean. Example:
In a schema in the App Express instance, create a user called "APP1_USER", and then
create view app1_user.people as select * from people@link_user@remotedb
As for the next question, using the built-in insert/update/delete processes will give you
ORA-01461: can bind a LONG value only for insert into a LONG column
among other errors. Apparently version 2.1 will fix this. See Cannot Update VARCHAR column in Remote DB
We address this problem by creating pl/sql APIs for DML, and then writing our own insert/update processes. Slows us down a little, but even with that, App Express remains a productive choice for us.
Another weird problem: auto-row fetch (built-in to HTML DB) doesn't work over db links when you have two columns for a primary key. Many ways around this, e.g. create sequence-populated primary key, create a view with single column that concatenates primary key column values (key1|key2)
Hope this helps!

Is it possible to migrate WebCenter Portal data from a SQL database to an Oracle database?

We have our WebCenter Portal applications set up using a SQL database. Now we're wanting to migrate to an Oracle database and I'm wondering if that is possible.

Yes it should be possible though i have not tried it myself. You basically export a file from mds ( xml) and import it into oracle db.
Thanks

Oracle database (10.2.0.4) and HTTP server / HTML DB conflict

Hi there,
I installed a fresh 10.2.0.1 (patched with 10.2.0.4) oracle database on Oracle Entreprise linux 5.7, and HTTP server + HTML DB products from the companion CD. Both are located in different home directory:
ODB: $ORACLE_BASE/product/10.2.0/db_1
APEX: $ORACLE_BASE/product/10.2.0/apex
I just discovered that logs files ($APEX/opmn/logs/) have filled up my entire disk this week end. After some googling / digging, I've read that there is a conflict between the ONS services that run for both products on the same port. Opening the configuration files of both products:
+$ODB/opnm/conf/ons.config+
+$APEX/opnm/conf/opnm.xml+ (btw, ons.conf is empty)
I indeed saw that they both use port 6113 as local port and 6200 as remote port. The workaround I've found in variuos places is to either change the port number, or unsuscribe ONS for the database listener (and sometimes both).
Question 1: what is the best solution ? what are the consequences for the database listener in case of unsuscribtion ?
I also saw that opnm.xml in APEX configuration file is making use of the $ORACLE_HOME environment variable, which I define in my /etc/profile as $ORACLE_BASE/product/10.2.0/db_1. So I guess the opnm of APEX is looking at the wrong place... Yet if I change ORACLE_HOME in my /etc/profile, I won't be able to run dbstart upon stgartup, as it is run using ORACLE_HOME in a init.d script...
Question 2: Can someone clarify things up about the exact relationship between oracle database and HTTP server ? How should I deal with ORACLE_HOME environment variable, which one use it and when... ?
Note that I'm completely new to Oracle (and hence APEX).
Thanks in advance!

There should be no conflicts - except for configuration ones.
Oracle is multi home capable. Thus multiple Oracle s/w products installed into different homes and these products running side by side.
The conflict is system resources - like a TCP port. That port cannot be shared by multiple processes. So you need to make sure that each s/w component that needs a TCP listener end-point, has a unique port number allocated for it to use.
As mentioned, the Oracle Apache server is an Oracle client with respect to Oracle client-server architecture. It simply needs a client OCI driver to connect to the Oracle database instance. So whether you run Oracle Apache on the same server as the database instance, or on another server all together - this makes no difference. The Oracle Apache s/w will be using its home for running. It has no need for anything from the database instance's home directory. Thus there are no conflicts - as long as you correctly keep them separated and not set the wrong home for the wrong component or include the wrong path (to another home's executables).
OK, so to summarize a bit:
- I should just be carefull when running startup script which will launch all services upon startup, i.e. changing the value of ORACLE_HOME before running each product startup script (dbstart => ORACLE_HOME = (..)/10.2.0/db_1, opmnctl => ORACLE_HOME = (..)/apex). I'm still quite worried because ORACLE_HOME is heavily used in opmn.xml but anyways.
- That's basically it: when each product's services are running, they do not use ORACLE_HOME (and such) anymore, hence no conflict from this point of view.
Also do not attempt to use IPC connectivity between the mod_plsql Apache module and the database instance. Does not make sense ito performance. Shared server should be considered and localhost TCP connectivity can be used.Well as I don't really know IPC yet, so hopefully I won't get into troubles. Just to be clear about that, i've this in my listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = apex.nwk)(PORT = 1521))
Does that mean that ICP will be used somehow ?
Thanks again from your help.

What I usually do in situations like this is that I connect to the database using a sql client and the same connection information as I specified to OIM and see if the attribute is present.
Perhaps you got the wrong db name? Or schema name?
Everything looks good so most probably there simply is some little typo somewhere.
Hope this helps

Windows 7 64 bit, Access 2010 32 bit, Oracle 10G client 32 bit, Oracle database 10.2.0.4 64 bit

I am trying to connect to an Oracle 10.2.0.4 database from Windows 7 OS - 64 bit using
Access 2010 32 bit and Oracle 32 bit client version 10.2.0.1 installed on PC.
My user requires a 64 bit Windows 7 OS for other needs.
Oracle ODBC driver is 32 bit from Oracle 32 bit client.
In Windows 7 OS 64 bit, ODBC DSN setup software is located in:
C:\Windows\system32\odbcad32.exe for 64 bit drivers - all DSN types setup and
C:\Windows\syswow64\odbcad32.exe for 32 bit drivers - USER DSN setup
When I run the ODBC Data Source Administrator, I see the Version number is 6.1.7601.17632
I setup a User DSN using the 32 bit odbcad32.exe with a 32 bit ODBC driver.
Our Oracle TNSnames.ora file has our standard entries which have worked for years
(Windows 7 OS 32 bit and everything 32 bit has connected for years too)
So when I configure an ODBC User DSN and leave all the default settings and press the TEST Connection button, it says it works.
But when I open the existng Access 2010 database (which does connect to Oracle in a Windows 7 32 bit PC environment),
1. I go to Access External Data ribbon tab / Link to the Data Source by creating a linked table / press OK
2. I select the Machine Data source = to the USER DSN name / press OK
3. The Oracle ODBC Driver Connect Window opens with Service Name = USER DSN and User Name and it wants a Password
4. I enter the correct password and I get the following error message:
ODBC call failed
[Oracle][ODBC]{Ora]ORA-12154: TNS: could not resolve the connect identifier specified
(#12154) [Microsoft][ODBC Driver manager] Driver's SQLSetConnectAttr failed IM006 0
[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed (#0)
I have tried a quite a number of fixes:
I have gone into the PC registry and cleaned out most or all off the Oracle client keys and
reinstalled the Oracle 32 bit 10g client. It didn't fix the error.
I read about the Oracle instantclient-basic-win32-10.2.0.4.zip with ODBC modules but I have Windows 7 64 bit.
Anyone experienced a problem like this and have a fix?

Thank you for your reply.
I did not get to try it because after I entered my question, I did a lot more internet Googling.
I found this small comment:
“There's a known issue where you get a 12154 error message running 32 bit software on a 64 bit OS using client 10201, and
It should be resolved by patching the client to 10204, which you do by applying the 10204 database patch to it.”
I searched around for the 10.2.0.4 patch for 10.2.0.1 Oracle 32 bit client.
When I contacted my Oracle DBA to ask if he had that patch, he said that I should try the 11g 32 bit client on the Win 7 64 bit PC.
We have a 10.2.0.4 Oracle database but he said the 11g client should work fine.
I tried it and it solved the problem!
With so many settings, configurations and permissions involved in ODBC, I am inclined to think that I missed a setting but
it was a bug in the 32 bit client 10.2.0.1.
Solved.

How to generate XML file from oracle database query result

Hi dudes,
as stated on the subject, can anyone suggests me how can i achieve the task stated above??
Here is a brief description of my problem:
I need to create a XML file once i query from the oracle database, and the query result returned from the database will be stored in XML file.
I'd searched around the JAXB, DOM, SAXP and the like basic concepts, but i still don't know how to start??
Any suggestions ???

Read this:

You might have to read more of the book to understand that chapter.

How can I connect to an oracle database remotely using telnet in DIAdem?

I need to query an oracle database on a remote server and store the result back in DIAdem. Does anyone know how to telnet through diadem and return the result?

DIAdem provides you with tools to connect to databases using SQL. Specifically, you can use SQL_Connect to open a connection to a database through a DSN (Data Source Name). The DSN has to be configured on the local machine (Control Panel -> Administrative Tools - > Data Sources) and has to point to the remote Database. You can map a network drive in the local machine so you can browse to your remote Database. The DSN will provide the link between DIAdem and the remote Database.
If your communication has to be throught telnet, then I suggest you try to use an ActiveX control. VBScript doesn't support Telnet natively, but it does support ActiveX controls. You can create one from Visual Basic or try to find a telnet client that has one already.

I have 2 pdf files in the table. I want to view this pdf from forms when the user clicks on the button. On when-button-pressed trigger I want to show pdf on the screen. Any help is appreciated. Not on the designer. I want to run form application.

We were able to do the same thing with Oracle Application Server and Oracle WebLogic Server. I cannot remember how different the processes were, but it seems like they were very similar. I am going to give you the instructions on how we implemented a "Read PDF" procedure on the WebLogic Server. If you are still on the Application Server you may have to do some Google searches, but it all boils down to the mod_plsql DAD Configuration file.
Our PDF was located in a table with the following structure:
CASE_DOCUMENTS
   (id_document                    NUMBER NOT NULL,
    doc_blob                       BLOB,
    note                           VARCHAR2(240),
    created_by                     VARCHAR2(20) NOT NULL,
    created_dt                     DATE NOT NULL,
    case_id                        NUMBER NOT NULL,
    filename                       VARCHAR2(100) NOT NULL)Based on that table structure we created a procedure named READ_PDF which you will reference below in the dads.conf file below:
CREATE or REPLACE procedure read_pdf (p_id_document IN number)
is
view_file     blob;
BEGIN
select doc_blob
    into view_file
    from case_documents
   where id_document = p_id_document;
OWA_UTIL.MIME_HEADER ('APPLICATION/PDF', FALSE);
HTP.P ('CONTENT-LENGTH: ' || DBMS_LOB.GETLENGTH (view_file));
OWA_UTIL.http_header_close;
WPG_DOCLOAD.download_file (view_file);
END;
GRANT EXECUTE ON read_pdf TO financial_user_role -- Name of role to execute
/Basically, you are passing in one parameter and that is the primary key for your table. You are selecting the pdf stored in a BLOB for that primary key. The commands below that allow the pdf to open up so you can view it – we got this off some search we did a few years ago.
Now, you need to add logic to your Oracle Form that will call the procedure above, but the URL is based on the dads.conf file that we will set up below… Anyway, we created a button on the form module with a label of "View". In the WHEN-BUTTON-PRESSED trigger the logic looks like this:
-- The View logic uses the DAD (Database Access Descriptors) method to view a .pdf file from the form.
-- The DAD was created on WebLogic Server with the name findadgen. This allows an http request be made
-- to the database.
declare
v_file          varchar2(400);
v_success       boolean;
ret_val         number;
v_http_link     varchar2(400);
begin
-- The format of the link is as follows: hostname:port/pls/DAD_name/procedure_name
v_http_link := 'http://finas03:8888/pls/findadgen/read_pdf?p_id_document=' || :case_documents.id_document;
web.show_document(v_http_link, '_BLANK');
end;The name of our WebLogic Server is "finas03" so that is what is listed in the URL. The "findadgen" is the name of the <Location> in the dads.conf file below, the "read_pdf" is the name of the procedure we created above, the "p_id_document=" is the IN parameter listed in the READ_PDF procedure created above, and the ":case_documents.id_document" is the reference to the primary key in our Oracle Form.
For WebLogic, you can either go through Enterprise Manager (directions below) or update the dads.conf file on the filesystem directly (if you update the dads.conf file directly then skip to step 4 and ignore step 5):
1.     Enterprise Manager -> Web Tier -> ohs1
2.     Oracle HTTP Server (pull-down) – Administration – Advance Configuration
3.     Select File – dads.conf
4.     Add something similar:
# ============================================================================
#                     mod_plsql DAD Configuration File
# ============================================================================
# 1. Please refer to dads.README for a description of this file
# ============================================================================
# Note: This file should typically be included in your plsql.conf file with
# the "include" directive.
# Hint: You can look at some sample DADs in the dads.README file
# ============================================================================
<Location /pls/findadgen>
    SetHandler pls_handler
    Order allow,deny
    Allow from All
    AllowOverride None
    PlsqlDatabaseUsername financial
    PlsqlDatabasePassword sdo_3#d1
    PlsqlDatabaseConnectString ffindbTNSFormat
    PlsqlNLSLanguage AMERICAN_AMERICA.WE8ISO8859P1
    PlsqlAuthenticationMode Basic
    PlsqlDefaultPage read_pdf
</Location>You are adding the <Location> section to your dads.conf file. The "finddadgen" is the name that you will reference in a change you fill make to your Oracle Form. The "financial" is the Schema, the "sdo_3#d1" is the password for that Schema, the "ffindb" is the database that the stored procedure is located on, and the "read_pdf" is a stored procedure you will have to create in order to read the pdf.
5.     Press the "Apply" Button
6.     Obfuscate the DAD password by running the dadTool.pl script located in $ORACLE_HOME/bin (This was done on Unix on our server with the following commands):
$> LD_LIBRARY_PATH=$ORACLE_HOME/lib;export LD_LIBRARY_PATH
$> cd $ORACLE_HOME/bin
$> perl dadTool.pl -f /u01/app/oracle/middleware/asinst_1/config/OHS/ohs1/mod_plsql/dads.conf
7.     Restart the Oracle HTTP Server using Fusion Middleware Control:
Enterprise Manager -> Web Tier -> ohs1
Oracle HTTP Server – Control – Shutdown
Oracle HTTP Server – Control – Start Up
If you followed the instructions above, you should have created a stored procedure, added logic to your Oracle form to reference that stored procedure, and created an entry in the dads.conf file. Once you move the form onto the server and you restart the HTTP Service, you should be able to view a pdf that is stored in a table directly from your Oracle Form.
