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 am using Report Builder 10.1.2.0.2. There is a table in a remote database with synonyms/links defined. I am getting error trying to access those tables. DBA says links/synonyms are correct and I am also able to access that table from SQLTool without error.
I can do a select statement on those tables from 'SQL Query statement' in data model.
Error is generated only if I try to use those tables in 'Formula' or in function/procedure.
I am trying to connect to a database located at my work from at home. I am running into the following issue (see command and error below):
ansichart@ansivm:~/src/perl$ sqlplus aspxdba/********@aspxp2 SQL*Plus: Release 11.2.0.3.0 Production on Thu Jul 18 21:15:09 2013 Copyright (c) 1982, 2011, Oracle.
All rights reserved. ERROR:ORA-12545: Connect failed because target host or object does not exist-- Here is my tnsnames.ora file (I have the service_name censored out for privacy reasons):-
I have verified that I can establish a TCP connection to this DB server on the port specified, using the same info from the TNSnames.ora file (see below):-
---ansichart@ansivm:~/src/perl$ nmap -sT -p 1521 orarac9-scan Starting Nmap 5.21 (URL.... ) at 2013-07-18 20:53 CDTNmap scan report for orarac9-scan (10.1.13.115)Host is up (0.0088s latency).PORT STATE SERVICE1521/tcp open oracle Nmap done: 1 IP address (1 host up) scanned in 0.09 secondsansichart@ansivm:~/src/perl$--
I have another terminal opened up to a server at work and I can connect to the DB with sqlplus just fine. I verified that the record for this database on the tnsnames.ora file is the same as it is at work. In conclusion, I can connect to the Database at work, but I cannot at home, even though I am using the same connection information and verified that port 1521 is accessible on this Database server from at home. So why can't I establish a DB connection?
I have created a function for knowing the status of link which connect me with remote database.function is as follows
--------------------------------------------------------------------------------------------- CREATE OR REPLACE FUNCTION get_status_db_link (p_db_link_in VARCHAR2) RETURN NUMBER AS rows NUMBER; v_code NUMBER; v_errm VARCHAR2(64); [code]....
Now functin should returns 1 when link is up and it should return 0 when link down but sometime when link is down it continues showing executing it hang my pc.
I have a strange problem of connecting Oracle Forms6i from our Remote site.actually we change our IP address of lease line, we connect to it.but when we connect locally,forms are running without any problem,but when we connect globally or from other sites it can't able to connect,even sql prompt and toad also connect from remote site,but when we try to connect forms(forms runtime) it gives error message(ORA-12203: TNS:unable to connect to destination).when we connect this application from local application(Forms) it can connect well but from globally it can't able to connect.
When I try to remotely connect to an Oracle schema using SQLplus, I consistantly get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Yet I can connect to the same machine, from my own machine just fine using SQLDeveloper.Here are the details I have collected so far
- I am using the instantclient for OS X - export DYLD_LIBRARY_PATH=/Users/jeff/instantclient - export ORACLE_HOME=/Users/jeff/instantclient - export TNS_ADMIN=/Users/jeff/instantclient/tns
The command line i ran : ./sqlplus seam_classoft/seam_classoft@//oracle11gtest.terida.net:1521/orcl
Its behind a VPN, so I'm not worried about posting my info.
My /Users/jeff/instantclient/tns/tnsnames.ora that I copied directly from the server looks like this:
I've tried changing SERVICE_NAME to SID = orcl, no change inbehavior. My original guess was that the database wasn't registered with the listener, but that would mean sqlDeveloper should fail as well, but it works.Here is out put of lsnctrl status:

I have installed Oracle 10g on one system and Oracle developer on another machine, means i have different machines for DB Server and Application server. It all working excellent inside the company premises, but if i want to access my Oracle DB and application server outside the company then it gives me problem..how to access application (forms and reports ) remotely outside the company...having same db.
I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.
After restarting the listener, we could connect using the connect identifier from the local server. However, when trying to connect from a remote client we received the error of "no listener". In the remote client the identifier is defined with host=ip_address. TNSping from the client to the host was successful.
When we changed listener.ora to host=up_address we could connect ONLY from the remote computer. Only after changing the host in tnsnames.ora file to the IP as well - we could connect from both the local server and the remote client.
I usually use host=localhost in the listener file (and the local tnsnames file) and never had this problem before.
i got static ip from witribe a broadband company in pakistan i am trying to connect database from client side computer who connect with internet when i ping my server it reply with good speed but when i try to connect database the message appear (Unable to connect Destination) but it works very well with Local Area Network computers. More how can we change port 1521 in client sides
I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter: Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is: CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
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?
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.
I want to update my table base on changes in a column of a table from remote database automatically. I just want to pick some updated column then update to my own. i have made a trigger but failed.

I have 2 database . One is production and other is Integration and I have one table "emp" which is on integration server and a synonym of that table with the same name"emp" on production. On production we have a proc in which we are using "emp", but some time our integration server goes down, so is there any way to ping the integration server inside the proc and if it returns success then we will execute the rest of code of proc , otherwise it will send a mail to us saying that integration server is down.
I have a simple script which fetch data from another SQL server database.
The remote SQL Server database is accessed by oracle thru gateway, and a simple DB link is made in local database to the remote oracle datbase (which actually access the MS SQL Server)
The SQL script empties all the data in local database, and fills it with the fresh data from MS SQL server.
Problem is sometimes SQL Server is down, and i lose all the data in local database. The script runs automatically as schedualed job. I want to make my script intelligent enough to terminate the script if the other database is down.
i am trying to load data into a table in a remote database schema, and my files are residing on another remote Server, Server having the files does not have a DB installed, i just need to know that if its possible or not..
As a part of requirement need to clean up some of database objects from database. Before cleaning up need to check for dependencies with in database and also on remote database.
Is there any data dictionary in oracle which proivides information about remote dependencies.
Any other way to get a list of remote dependencies other then manual checking.
I have one PLSQL package that does a join of two tables of remote database instance via the datalink. I just wonder where the most calculation(the join) is done, local machine or remote machine? Is there any best practice to have a better performance for such configuration.
