I am trying to develop a web application with C # VS.net, my application is to connect to an Oracle database on a server (LAN), the problem I want to connect to the database without install oracle or ODP on my client machine.
View 1 RepliesI have the following computer/setup:
Acer laptop, Intel Processor w/ Windows 7 Professional (64-bit)
Delphi 2010 Professional
Oracle XE (+ the Oracle XE client that comes with it)
I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator.
- Data source name: bt_user
- TNS Server Name: localhost/xe
- user bt_user
- Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC)
- Set database name to "bt_user".
- Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form.
- Select "connection string" and open the dialog.
- Click "build string".
- Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection.
- In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1)
- Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?
I have created an Oracle database on my Windows XP system but cannot connect from a php script
CODE
<?php
if (!$db = @ocilogon("big", "big", "s7s"))
{
$error = ocierror();
printf("Error was: %s", $error["message"]);
die();
}
$stmt = ociparse($db,"SELECT count(*) FROM members");
ociexecute($stmt);
?>
When I created the database the connection I used was s7s but whether or not I include that name or just use the ID/password that script will not connect.

View 8 Replies View RelatedI am attempting to connect to an Oracle 8i database via the Oracle 9.02 ODBC driver and I am receiving the following error message upon testing the connection in WinXp's ODBC Data Source Administrator dialog box: "Unable to connect SQLState=IM004 [[Microsoft]][[ODBC Driver Manager]] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed" .
I am running Oracle Client 9.2 on a P4 machine running winXP.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the parameter of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
)
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered or the server may not be ready for a connection. You can check the server and retry, or continue.
I have created two database one for production and another one for test.I created both database in shared_server mode(by using dbca),after than I did not change anything.My problem is when i connect to test database from outside lan through static ip its working well,but when i connect to production database which is not connected. I checked and compared two databases,then I find there are some changes in dispatcher and mts_ dispatcher parameters.And I used this query to check the shared_server status,
ie.select * from v$shared_server,
the output of this query is attached with this post.

View 3 Replies View Relatedlet me know the procedure to connect to Oracle Database from Ms-Access.
We are using Windows as Operating System.
i tried for 3 days to setup a connection between my oracle database 11.2 (resides on 2003,64 bit Microsoft windows) and a mysql database (resides on 2003,32 bit Microsoft widows).
i used dg4odbc 64 bit which was installed on oracle server, my steps was as follows :
1- configure ODBC driver (MYSQL 3.51 odbc) on oracle server that connect to mysql database and the connection was tested successfully (the name of odbc dsn is DG4ODBC).
2- configure the listener.ora file (which resides on dg4odbc installation path) that contains the following :
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxxxxxxxxxxx)(PORT = 1511))
[code]....
3- configure the tnsnames.ora file (which resides on oracle database path) that contains the follwoing :
DG4ODBC =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=xxxxxxxxxxxx)(PORT=1521))
(CONNECT_DATA = ( SERVICE_NAME = DG4ODBC ))
(HS=OK)
)
4- configure that initdg4odbc.ora file that resides on the dg4odbc installation.
HS_FDS_CONNECT_INFO = DG4ODBC
HS_FDS_TRACE_LEVEL = off
5- restart the gateway listener.
6- test DG4ODBC service by tnsping which was successful .when i try to get some data from mysql database by SELECT * FROM MDL_COURSE@DG4ODBC query,the query take some time (15 second !!) and return
ORA-12154: TNS:could not resolve the connect identifier specified
In fact I have around 50 excelbooks that are connect with oracle via ODBC/or any other way. My task is to build the login screen on form 10g. This form will validate the user via .dll after successfully validation, Form will connect to specific oracle user. This Login Screen will call the new form that will execute the query for the list of excel sheet [table that will keep the name, description and path of the excelbook]. User will select the one excelbook to open. As user will select Excelbook should be open. Now this excel book should be connected with specific oracle user.
Question 1: How to open the excelbook, that excelbook should be connected via form 10g login screen. After connection excel has its own micros to run he query from oracle database.
Question 2: How I can create the mirco into form 10g to run into excelbook/excelsheet.
Question 3: How I can pass the query or function/procedure to the excelbook/excelsheet.
all of the client cann't connect the db,and using sqlplus / as sysdba also cann't login there are many error of TNS-12535 and in the listener.log

For example, I have 3 database, database 1 and database 2 connect together by database link db_link1, database 2 and database 3 connect together by database link db_link2.
I want to ask: Can I connect from database 1 to database 3 ? ( Of course don't use database link between database 1 and 3, just use database db_link1 and db_link2 )
Both db_link1 and db_link2 are public database link.
Can I restrict user access by 2 these public database link ?
