Can Connect From Database 1 To 3
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.
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 ?

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?

I do not know how to create a connection between oracle to SQL server using topology manager on my application. I understand that I must create a logical and physical architecture to create the connection and the logical and physical architecture is running under topology manager.

I recently installed Oracle database 11g XE onto my home computer running Windows 32 bit, but I can't connect to the database. I also have Oracle 10g R2 installed on my computer, and I can still connect to it finely. When trying to make a connection in SQL DEVELOPER, I get this error
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I tried to tnsping the XE database and it returns successfully.

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.

I installed oracle 10g and developed simple software using forms 6i. Its working well as a stand alone system.
I want to share it in network. so I installed forms 6i as oracle client , copied the tnsnames.ora from the oracle installation path to forms installation path.(inside NET80/Admin folder)
When i try to connect with user name and password , it comes ORA-12203 Unable to connect to destination. I checked LSNRCTL in the database machine, it is listening.

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)
)
)

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.

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.
