Connect Oracle Database From Delphi - Could Not Resolve Connect Identifier Specified

Oct 6, 2010

I 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?

Forms :: Run Form From Formbuilder Doesn't Connect To DB

Jan 20, 2012

I have DevSuite 10g on my XP. Running a form from frombuilder, for testing or debugging purposes for example, always worked. I am using OC4J.Now we moved the DB-User, to which I normally connected in the above scenario, to another DB-Instance, but left username and password unchanged. I changed my connection in formbuilder to the new destination and formbuilder succeeds when connecting to the DB. Compile etc. all ok.But running a form from formbuilder raises ORA-01017. After that, the forms logon screen is shown and has exctly the username and ORACLE-SID defaulted with my connection in formbuilder itself (only username is "upper"ed).

So apparently the formbuilder connection information or oarts of it is passed to the runtime. When I then give the password in the logon screen connecting succeeds. How is the connect information from formbuilder passed to the runtime?

Nov 10, 2011

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.

Both db_link1 and db_link2 are public database link.

Oracle Database - Cannot Connect From PHP Script

Jul 19, 2010

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.

Networking And Gateways :: Cannot Connect To Database

Nov 2, 2011

I installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files

tnsnames.ora
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = myservername.domainname.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
[code]....

# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.

Can't Able To Connect To Local Database Instance

Oct 31, 2012

I cant able to connect to my local DB instance. Oracle service for DB instance will be started running when the system boots automatically.I faced this problem before, I was instructed to boot my system without network connection. It worked for few days. Suddenly I cant able to connect to my local DB instance again, even though I am booting my system without network connection.

This is the configuration I have in tnsnames.ora in my local machine.I have the host as localhost, because local machine is laptop and IP will change periodically.

CSS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = CSS)

Connect To SQL Server Database Via Toad

Jun 25, 2013

how to connect to sql server databases via toad. I have used toad to connect to oracle databases, but never to a sql server database. To connect to an oracle database, we first install the client and then add the tnsentry of the database to the tnsnames.ora file and then we can directly connect to the oracle database right?So I was wondering if there are any steps like that to be followed to connect to the sql server databases.
