These are the steps to authenticate the user using Operating system.But still i am not able to authenticate user using os.
Just try it out and let me know if you are able to authenticate.
1)create user ops$user1 identified by externally;
2)grant privileges.... to ops$user1;
3)In pfile edit the following parameter
os_authent_prefix=ops$
remote_os_authent=true
4)restart db;
5)#useradd -g dba -md /home/user1 user1
6)#su - user1
/home/user1/>$sqlplus
bash:command not found.

How is the best way to connect to the Database ?

I just have a question regarding to the connection to the Oracle DB.
Every time I create a new JSP I am writing java code such as:
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = DriverManager.getConnection("jdbc:oracle:thin:@host:1521:DB",
"user",
"pwd");
Is there a way I can reuse the connection that we create on JDeveloper on the tab Connections, under the Database node ?
Because I would like to centralized more the way how I connect to DB.
Thanks!
Giovani

That is a nice solution, but only works if you use embedded OC4J, if not you must define datasources, maybe in standalone OC4J, OAS, JBoss, etc
this is because the embedded OC4J automatically create datasources if it sees database connectiones created through Connections Tab

Application module with no connection to the database in jdeveloper 10.1.3

I have a number of programmatic bc view objects and entity objects which i have implemented through the time from different projects and now that i have collected them i want to add all of them in a reusable application module. However i don't need a connection to the database for this application module. Is it possible to enforce the application module to circumvent the db connection?

Hi user,
Just out of curiosity, why would you use ADF BC for that - if I had a bunch of non-db data sources, I'd probably use POJOs and create POJO data controls.
I didn't look in 10g, but in 11g, the ApplicationModule has a method called getDBConnectionRequired() that you could override to see if that solves your issue.

Connect to the database of auto Hosted App on Office 365

Hi All,
I developed a custom Application for SharePoint on top Office 365 in Auto-hosted mode. The application has SQL database which will be deployed to SQL Azure.
I would like to read some info from the database but using another tools not from inside the developed application (e.g. SharePoint designer, PowerPivot) to generate some reports.
When I try to connect to the database after the application installation using SharePoint Designer I get the following error message:
Cannot open server 'xxxxxxxxxxx' requested by the login. Client with IP address '41.239.166.230' is not allowed to access the server. To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create
a firewall rule for this IP address or address range. It may take up to five minutes for this change to take effect.
Login failed for user 'db_c6ab7aa1_4572_4d36_b99d_741dee28a139_dbo'.
This session has been assigned a tracing ID of 'c13ecefa-6aa2-4154-86f8-18d272c73b86'. Provide this tracing ID to customer support when you need assistance. (Microsoft SQL Server, Error: 40615)
And since I am using the Autohosted mode, I don;t have he Windows Azure Management Portal. is there a workaround for this issue?
Kind Regards,
Thanks in advance for you help. Mahmoud

Hi m_3ryan,
The error message shows you need to add your IP Address to the firewall rules of the SQL Azure to get yourself connected. As you deploy the database to SQL Azure, you mean you cannot open window azure management portal?
Follow the steps in below article, check whether it works:
How to: Set Firewall rule to connect to SQL Azure – sp_set_firewall_rule:

How can I speed up the connection to the database?

I am running a JSP application with regular JavaBeans not EJB and connecting to the database through these beans. The connection is set to stay in memory as long as the bean is in session. However when I am running more than 7 sql statements seperatly the execution of the page slows down.
I have tried using connection pooling but doesn't help much.
I am not using the JDBC setting in JRUN, I am connecting through the jdbc.odbc drivers provided by the JDK. Basically coded the connection and the connection pool.
Is there something else that can be done to speed up the execution of the page?
Thanks in advance

Thank you all for your input I was trying to work this project to learn JSP so I am not looking at purchasing any drivers right now. That is the reason why I stuck to the JDBC-ODBC Bridge. Are there any other drivers available for MS SQL Servers that are free.
Jschell,
That suggests you are taxing the system. It could be >connections. It could also be network, cpu, bus, etc. It >could also be memory, if your app starts swapping to >the hard drive it will get substantially slower.How can i figure out which of the above (i.e. memory, cpu, connections, network) are causing the problem.
(Presumably you explicitly close your >ResultSets/Statements/Connections when you are >done with them.)You are right about that yes I am closing them at the end of the session, which I think should be after all of the SQL's get executed but I could be wrong it might be openeing a new connection for each SQL which inturn might be the reason for this whole problem. I will take a look into that.
Thank you all once again.

Connect to the Database using TOAD

Hi
I've installed 11.5.10.2 on and using DB 9.2.0.6.0 on Redhat 4 everything works ok.
but when i try to connect to TOAD i get this error ORA-12537 TNS:connection closed.
do i have to do any setup's?
please help.
Thanks

You need to register your host through OAM or disable the SQLNet restriction so that you can connect to the database. Check the following note for more details:
Note: 291897.1 - 11.5.10 New Features : Managed SQL*Net Access from Hosts

Unable to connect to the database instance using Enterprise Manager.

I just install Oracle 10gr2 in my computer and after successful installation created a database instance which also install successfully. I then configure the listener using Net Manager and then start the database instance, the listener and dbconsole, everything seems to work fine and checking the status of this services from the command prompt indicates everything started successfully. But when I try to use Enterprise Manager I was directed to the Database Down Page with a message unable to connect to database instance. I try to use startup and perform recovery but every time I log-in to the database an error message comes out:
SQLEXCEPTION
ORA-00604: error occurred at recursive SQL level 1
ORA-12705: Cannot access NLS data files or invalid environment specified.
It seems for Enterprise Manager to connect to the database it needs to access this NLS(National Language Support) data files or specify an environment variable to point to this data files. I am just new to Oracle and I am having difficulty solving this particular problem. Where is this data files located and how do I configure Enterprise Manager to access this NLS data Files?
Any help however small will be highly appreciated.

Are you able to connect to the database via SQLPlus?
What Operating System are you using?
Assuming Windows, can you RUN regedit to open Windows Registry and check the value or NLS_LANG when you select
HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_<your_oracle_home>
Examples of vaules you may find:
1. ENGLISH_UNITED KINGDOM.WE8MSWIN1252
2. AMERICAN_AMERICA.US7ASCII
3. AMERICAN_AMERICA.WE8MSWIN1252
4. FRENCH_FRANCE.WE8MSWIN1252
5. GERMAN_GERMANY.WE8MSWIN1252
If you are not able to connect to SQLPlus, from the command prompt try setting one of the above:
e.g.
D:\>set NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
D:\>sqlplus /nolog
SQL>connect sysman/password

How does it connect to the database

can anyone pls tell me how the below coding connect to the database, and if i want to change to use other type of connection, which part of the coding should i use? thank

Enterprise Manager not able to connect to the Database Instance

After logging into the OEM as a SYS user , I was able to mount the database . The Database status shown to me as below,
Listener - up
Agent Connection to the Instance - unavailable
Database instance- down - message - Enterprise Manager is not able to connect to the database instance.
After that I tried to connect to the database through sql developer , I was able to connect using connection for the SYS user and able to run the queries .d
So How can I be able to connect to the Database Instance using OEM ?
Please suggest me what to do or what to check ...
Your help will be appreciated...

java.sql.SQLException: Listener refused the connection with the following error:

The Connection descriptor used by the client was:
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=orcl)))ORA-12514 ALWAYS only occurs due to a problem on DB Server system.
One cause of this problem is when the Oracle database is down & needs to be started.
A remote client send a request to the Listener asking to be connected to a specific service.
If/when the listener does not know anything about that service, the listener responds with ORA-12514
post results from the following two OS commands:
lsnrctl status
lsnrctl service
Since every connection request to the listener gets logged, listener.log file will contain a line with 12514 as status code.
This line contains valuable debugging details. So post this line & surrounding lines.
for additional debugging suggestions read the URL below:
