How do I connect to a database...

Hi, my coworker setup a server for me at my work, and he gave me the following listener....
PRNSCXDB_PRIMARY =
(DESCRIPTION = (SDU=32768)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dm2c0h-d00.on.vcol.ca)(PORT = 1545))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRNSCXDB)
SD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = mtrlpq02923.lleb.corp.vcol.ca)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SD.llep.corp.vcol.ca)
You seen, i dealt with database only on how to retrieve data and delate/adding tables. I am stuck here, because I don't know where to input this in SQL developer. Can you guys please help me, i really want to learn how to connect to this server in SQL developer.

This has to be pasted to your tnsnames.ora file, If you are using oracle 10 g client version then tnsnames.ora file reside in the following path
Your Drive\oracle\product\10.2.0\client\NETWORK\ADMIN
If you are using Oracle 9i the tnsnames.ora file is in the following path
Your Drive\oracle9i\network\admin
- Open the tnsnames.ora file and paste the entry
PRNSCXDB_PRIMARY =
(DESCRIPTION = (SDU=32768)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dm2c0h-d00.on.vcol.ca)(PORT = 1545))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PRNSCXDB)
SD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = mtrlpq02923.lleb.corp.vcol.ca)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SD.llep.corp.vcol.ca)

How can I connect to a database from ipaq with cldc??

how can I connect to a database from ipaq with cldc??

Hi Again
There is a library by Mimer which allows you do connect to a Mimer SQL Server, don't know must about it, but here is a link.
http://developer.mimer.com/
If that doesn't suit you, I suspect that you will have to use some sort of proxy solution. Either by creating a servlet to accept the sql string you want to send, or by creating your own custom proxy server running J2EE. The servlet or the proxy server must be able to receive an SQL String, do the query to the actual database and return the results in some sort of format to the mobile device. Maybe just a space delimited string.
Hope this helps

How do with connect to informix database?

how do with connect to informix database?I think use own sminformix.jar with java studio creator

Two steps:
1. Tell Creator about the Informix drivers:
Data Sources -> Edit Database Server Types -> New
Navigate to the appropriate jar files; besides sminformix.jar, you will need smbase.jar and smutil.jar. They can be found in the Java Studio Creator release, for use within the IDE.
Fill in the other parts of the dialog. I don't know what form Informix URL's take; you may need to look on the Informix site for that.
2. Create an Informix Data Source, using the newly defined Server Type.

How can I connect to my database ORACLE from JavafX?

Hi! ¿Anybody have a example to learn how could connect my ORACLE database from my javafx application?

Just use JDBC like you do in a regular Java program.
Either you translate the code to JavaFX (creating Java objects, etc.) or you do a Java layer to simplify access.

I think there are 3 ways to do so
1. JDBC
2. ODBC-JDBC bridge
3. don't remember the third
I would check it with JDBC section of the javasoft site. Also since your web server is on a linux box, you probably will not be able to use ODBC-JDBC bridge. I would try the JDBC method, but that requires you to get the JDBC driver for the database that you are trying to connect to!
good luck

How can I connect to a database using Java Web Start?

When I run the application without Java Web Start, the program can get the driver and connect to the database. However, when I try to use this same application with Java Web Start, the program can not load the driver. Why is this happening? I am using a mySql database driver.

I assume you are trying to connect using JDBC, are did you include the jdbc jar in your resources ?

How can i connect to remote database from netbeans

Hi,
I have got MySQL database server installed and running on a different machine. Is there any way to connect and browse database remotely using netbeans 5.5?
I have added connector/driver for that database. i can connect and browse the database with host: "localhost" and port number. But when i specified the ip address of that machine, it gives me error.
Can anyone help please.
cheers.

well, its not working in App server either.
In App server admin console, on that connection pool if i define servername as "localhost", it works fine. If i change it to the remote machine's ip address, then it doesn't work.
Any idea will be appreciated.
cheers.

How can I connect to WinCC database (best by use of OLE DB provider)?

Post Author: MarkusR
CA Forum: Data Connectivity and SQL
Hello,
if I connect to the WinCC database by using the WinCC OLE DB provider I do not get the tables I expect.
E.g. I would like to see the AlgViewEnu or other tables/views of AlarmLogging or TagLogging.
Who can help?

Hi
I have not used asp.net with CS4, due to it using an old version of the framework, so unfortunately I cannot really help in solving the problem. But I can remember having a similar problem with DW8, a tutorial for connecting to the database in DW8 is - http://www.webdesign.org/html-and-css/tutorials/asp-net-in-dreamweaver-8.7367.html. I also seem to remember that the connection required the old, (very old) Jet4 access database connector to be installed to work correctly.
These problems, and the fact that MS keeps updating the framework every year or so, (which are often not backwardly compatible) are why I use Visual Studio for .net C# sites, and no longer actively develop them, but I must admit I still prefer C# to PHP.

How can i connect to a Database Server (live data)?

hi,
i'm trying to figure out how i can create a dashboard that's connected to live data coming from a Database server. i have the username and password and the DB name, but can't find a direct way from within SAP dashboard design where i can make the connection.
MUST i go through XML?
i know other tools like Tableu that allow direct connections to the server.
is this possible?

Hi Sam
Please refer to the tutorial http://scn.sap.com/docs/DOC-7946 and under "Connecting to Data Sources" section you will get the step by step guidance of various data connectivity options..
Basically the options available under Data > Connections > Add and Query Browser in Dashboards 4 are your options.
If you want to write direct SQL to get data you have to use add-ons InfoBurst like InfoBurst infosol.com/solutions/infoburst/

How To Disable Connections or Freeze Database

I have no need to do so right now but I'm curious what the recommended process would be if there's an issue with Oracle 11g & one had to keep the database engine up and running but stop all users from connecting while 'X' was investigated. Do you guys have any recommendations (examples) on standard / simple procedure to stop users from connecting to Oracle 11g and querying the database or altering the database?
Thanks for any info and like I said, this is a hypothetical question as to what would one do if this issue came up. I don't have an actual performance issue that requires me from limiting database access.
Thank you!

Totally wrong on both counts. You may get some initial satisfaction from copping an attitude and trying to blame others for your omissions but that is not the way to learn.
If you want to learn you need to be able to analyze what other, more experienced people are trying to tell you and then try their suggestions.

ALTER SYSTEM ENABLE RESTRICTED SESSION;

At that point you should have thought about that reply and try to understand what was meant.
Did you recognize that as an Oracle command? If not you should have followed up with questions like
1. what does 'ALTER SYSTEM' mean? What is that?'
2. where can I get more information about that ALTER SYSTEM reply you provided?
If you recognized the reply as an Oracle command then it is obvious how to get more information about it. You check the Oracle documentation. If you don't have it you can 'Google' for it.
Did you do that? Apparently not because your next question was

So if I run this command as SYS, does that mean . . .

That is an indication that an OP is too lazy to do anything at all to answer their own question. Why should we look something up in the documentation if you won't bother to do it?

I am sorry to see that GOOGLE is broken for you.

Perfectly appropriate response for someone that is too lazy to do any work. Especially after you were given the exact answer you ask for.
So let's see what the result is if you had thought about exactly 'why' you were given this response.
I recognized ALTER SYSTEM as an Oracle command so my first thought is to read the Oracle documentation for that command to see what it says. I have the Oracle documentation but in order to provide a link to users asking questions I prefer to find the doc on the net so I can provide a link that lets a user read the same documentation, for the same version of Oracle, that I read.
So I entered a Google search
>
oracle 11g doc ALTER SYSTEM ENABLE RESTRICTED SESSION;
>
And what do you know?
The VERY FIRST RESULT was for
>
ALTER SYSTEM - Oracle Documentation
>
which took me to this link - http://docs.oracle.com/cd/E11882_01/server.112/e17118/statements_2014.htm
And if you search for RESTRICTED SESSION (words in the command you were provided) you will find
>
RESTRICTED SESSION
The RESTRICTED SESSION clause lets you restrict logon to Oracle Database. You can use this clause regardless of whether your instance has the database dismounted or mounted, open or closed.
Specify ENABLE to allow only users with RESTRICTED SESSION system privilege to log on to Oracle Database. Existing sessions are not terminated.
This clause applies only to the current instance. Therefore, in an Oracle RAC environment, authorized users without the RESTRICTED SESSION system privilege can still access the database by way of other instances.
Specify DISABLE to reverse the effect of the ENABLE RESTRICTED SESSION clause, allowing all users with CREATE SESSION system privilege to log on to Oracle Database. This is the default.
>
Which answers the question you ask instead of looking it up yourself.
So your comment that
>
When searching Google, you don't get the details that could make or break an idea you have but rather generic instructions if that
>
is totally wrong. I searched Google and got the exact details that were needed.
And this?
>
Yes all this could have been easily found on some janky site linked off Google but you miss specific reasoning and theory
>
The Oracle doc was the very first link provided! And it wasn't a link to 'some janky site' - it was the official Oracle documentation. And it contains the reasoning and an example.
So next time you need help
1. leave the attitude behind - it doesn't impress anyone and makes it less likely that people will want to help you in the future.
2. check the documentation first - if you don't know how to find something in the docs then ask what it is called or what doc it is in.
3. when you are given a command or example go back to the doc and read the complete command and all of the syntax options. If you have any questions about how to interpret something then ask.
4. demonstrate that you are willing to do more work to find an answer than any of us - it's your problem - why should we spend time helping you if you aren't willing to spend your own time?
