I am exploring the options for file based databases for offline applications where there are no overheads of database installations. We have a system which has Oracle database with more than 500 tables. We need to write a lightweight application (offline) in .net which will run from USB drive and write data to USB drive only.
Existing system has a data layer which writes data to Oracle 10g Enterprise Edition database. The offline application will have more or less similar data entry forms and storage structure. In order to reuse data layer of existing system (stored procedures) can the Oracle Lite be used as a database which can run from USB drive?
I understand Oracle Lite has a suport for synchronization with the server (our main database in this case) by which data can be synchronized with minimum overheads. How the Oracle Lite is licenced if I have 300 odd users of this offline applications. I need to use only database part of Oracle Lite and not mobile server.
Is there any official document from Oracle which tells us how to export apex applications from command line instead of using the GUI from within apex ?
When I googled I saw some links from apex users who had written as how to export using ApexExport utilities, but since we are in windows environment, we are having hard time getting the class_path,java_home...etc setup properly. I guess its not just me most of them would have encountered it.
But I am looking for an official document from Oracle ? ( exporting Apex applications from command line in Windows Environment ).
I've just patched a development oracle environment (RAC 11GR2) with temporary patch 8730312. I would like to do same thing on Production RAC. Is it necessary to test all applications on dev environment with this kind of patch before deploy it on Production ?
We have a scenairo in which we have two servers one is a Oracle server and the other is SQL server and we need to enable automated Emails from the oracle DB server. As the Oracle server is not whitelisted and we have a SQL server which is already whitelisted so is it possible to connect from Oracle server to Sql server so that the automated emails will be generated from the sql server (as it is whitelisted) and we do not want to whitelist the oracle server.
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.
Web Server(port80) and SSH Server(port 212) and Oracle client with sqlplus (192.168.137.2) || || SSH client (192.168.137.1/128.21.31.111) || || Oracle Server (port 1521) (128.21.31.112)
my php program have to access the db on oracle server, and then i do this on my SSH client
We are unable to connect to Oracle 11.1.0.7.0 from Oracle Forms 4.5..However we are able to connect using Oracle forms 6i
Now Forms 4.5 is old and not supported, however apart from Tests I will need prove it to the higher ups...Do we have any link, document which will cover such compatibility issue?
I am trying to Push the data from Oracle which is running in HP-UNIX to SQL Server. But don't know the efficient way to connect the SQL server from oracle which is running on HP-UNIX.I have heard about oracle Heterogeneous Connectivity but don't know exactly how to implement it in Unix environment.
I have Oracle 9i DB in windows 2003 server, I want to access this DB from Linux desktop. Is there any 'client software' is available to connect Or procedure to connect the DB.
I was trying to connect to SQL server from Oracle using Oracle heterogeneous services (HS).But I found that I do not have HS installed on my system. It was mentioned in Oracle website that we need to run 'caths.sql' script under the path $ORACLE_HOME/rdbms/admin.
But I do not have any such folder(rdbms) in my $ORACLE_HOME.What does it mean? And how can I install HS alone on my system(Since I already have oracle)
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

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've stucked with a query. Let me explain the situation: I have a table that i store the IDs of logically equal records.
For example; A = B B = C X = Y Z = Y
My query must return all equivalent records. If you call the query with parameter 'A', the result set must contain B and C. And if you call the query with parameter 'Y', the result set will contain X AND Z. I have thought that i can write the query wity using start with connect by statement. But the query does not work as i expected. Here is my code and sample data:
create table temptable (ID1 number,ID2 number);/ insert into temptable values(11,12);/ insert into temptable values(12,13);/ insert into temptable values(13,14);/ insert into temptable values(13,15);/
SELECT distinct ID1 from ( SELECT * FROM temptable START WITH ID1 = 13 OR ID2 = 13 CONNECT BY NOCYCLE
[code]...
In my sample the equality definitions is; 11 = 12 12 = 13 13 = 14 13 = 15
When i call the query with parameter 13, i'm expecting to get 11,12,14,15. But it returns only 12,14 and 15.
I am upgrading an application from 9i to 11g and I've been told that the connect by prior sql is broken. While I am waiting for the example and the error message, is 11g pickier about looping than 9i was? some documentation on 10 or 11 changes to hierarchical queries?
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.
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 have installed Oracle 10g XE in my laptop having Windows 7 home 64 bit OS..I have created some users in the oracle and iam able to connect these users through cmd prompt..But the issue is that iam unable to connect to the database through TOAD..
I have given the user name and password and database as XE and connect using as : XE but still iam getting the error as "TNS could not resolve the connect identifier (XE).
Unable to connect in TOAD in ORACLE 11g through sys user.
I am using Toad for ORACLE version 9.0.0.160 and ORACLE 11gR2 (11.2.0.1).
I make the FALSE to "sec_case_sensitive_logon" parameter hence not able to login through sys user. I can logged in through system user without any issue.
Recently i have installed oracle 10g.2 in my laptop under Win-7 64bit. But cannot connect oracle from Windows form [C#], Office application[Excel] and odbc. Showing error[Tns could not resolve the connect identifier specified Drivers SQLSetconnectAttr failed ]
Though I can connect oracle from toad and sqlplus and form 6i.
My OS is Linux and I installed Oracle 10.2. Everything is fine.I can use sqlplus, exp, imp etc with no problem.Now I have created another linux user test in /home/test. I unzipped basic-10.2xxxxxx.zip (/home/test/instantclient_10_2) and exported LD_LIBRARY_PATH.I guess I have installed instant client in this way.
My testOra.cpp:
#include <occi.h> int main() { return 0; }
This test.cpp would not compile. It cannot find occi.
I am having a problem understanding the relationship between users and databases within Oracle. I have a user "big" that logs on successfully on another machine to database "s7s" but on a different machine fails to connect. The following may be interesting:-
