Connect Oracle Database From Delphi - Could Not Resolve Connect Identifier Specified
Oct 6, 2010I 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?

Sep 13, 2011I've only successfully duplicate a standby database.
from the alert log

Quote:
As part of the duplicating operation, RMAN automates the following steps:
Creates a control file for the duplicate database
Restores the target datafiles to the duplicate database and performs incomplete recovery by using all available incremental backups and archived redo logs
Shuts down and starts the auxiliary instance (refer to "Task 4: Start the Auxiliary Instance" for issues relating to client-side versus server-side initialization parameter files)
Opens the duplicate database with the RESETLOGS option after incomplete recovery to create the online redo logs (except when running DUPLICATE ... FOR STANDBY, in which case RMAN does not open the database) when duplicating for standby database it does not create online redo logs. Duplicating a standby database does not creates online redo logs.
how should I add the online and standby redo logs. If I transfer the redo logs from primary to standby, it always encountered the the following error

Jun 2, 2011i 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
