Lot of DataBase connections

Hi,
I am using OC4J as web container and Oracle 8i database on Sun solaris. I am using following scheme to access database connection.
I have one Properties file that carries information about the driver,url,user and password
I have one class RDBMServices. In constructor I reads that properties file. I have one getConnection method that setup connection Following is the code
* Gets a database connection
* @return a database Connection object
     public static Connection getConnection()
     Connection conn = null;
          try
               Class.forName (sJdbcDriver);
conn = DriverManager.getConnection (sJdbcUrl, sJdbcUser, sJdbcPassword);
          catch ( Exception e )
          System.out.println(e);
          return conn;
I also have one method that is used to release connection.
* Releases database connection
* @param a database Connection object
     public static void releaseConnection (Connection con)
          try
if (con != null)
          con.close();
          catch ( Exception e )
Ok now in every JSP page where I need database access, I just create object of RDBMServices and execute queries on it. When I am done then I just call releaseConnectio() method to release that connection. So I am doing this in every JSP page. My problem is that I have lots of database connection open eventhoug I am releasing connection. For example I ran 50 users test and they Open 150 connection becasue every user goes through three pages. Please help me how I can get rid of this problem. THANKS

This example demonstrates how to configure a JDBC source and how to make a
JNDI lookup to access it. This example assumes you are using the scott database
user and EMP table exists in SCOTT schema.
1. Create an new entry in the $J2EE_HOME/config/data-sources.xml file as
follows. Make appropriate changes to the connection information.
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="OracleDS"
location="jdbc/OracleDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OracleDS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="scott"
password="tiger"
url="jdbc:oracle:thin:@localhost:1521:ORCL"
inactivity-timeout="30"
/>
2. The following Servlet (GetDSUsingJNDI.java) demonstrates how to make a
JNDI lookup to retrieve a JDBC data source named "jdbc/OracleDS".
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import javax.naming.*;
import java.sql.*;
import javax.sql.*;
public class GetDSUsingJNDI extends HttpServlet {
InitialContext context = null;
DataSource jdbcURL = null;
Connection conn = null;
public void init(ServletConfig config) throws ServletException {
super.init(config);
// Obtain connection using JNDI Lookup
try {
context = new InitialContext();
jdbcURL = (DataSource) context.lookup("jdbc/OracleDS");
catch(NamingException e)
throw new ServletException("Error looking Data Source", e);
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = new PrintWriter (response.getOutputStream());
out.println("<html>");
out.println("<head><title>Getting Data Source using JNDI Lookup</title></head>");
out.println("<body><H1>Getting Data Source using JNDI Lookup</H1>");
// Connect to the database
try {
Connection conn = jdbcURL.getConnection();
out.println("Connected to database successfully ..");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT ename FROM emp");
out.println("Results of the query");
// Display Results of the SQL Query
while ( rs.next() ) {
out.println( "<br>" + rs.getString("ename") + "<br>");
conn.close();
catch(SQLException e)
throw new ServletException("Error connecting to Database", e);
out.println("</body></html>");
out.close();
3. Compile the servlet using javac.
D:\j2ee\home>set CLASSPATH=D:\j2ee\home\orion.jar;D:\j2ee\home\jndi.jar;D:\j2ee\home\lib\classes12.jar
D:\j2ee\home>javac GetDSUsingJNDI.java
You have to include D:\j2ee\home\jndi.jar in the libraries for the project
properties for the project in the Jdeveloper to compile this in Jdeveloper.
4. Deploy the servlet on OC4J by copying the GetDSUsingJNDI.class to:
<9iAS ORACLE_HOME>\j2ee\home\default-web-app\WEB-INF\classes
5. Run your GetDSUsingJNDI Servlet and your servlet should be able to
connect to the database successfully.
http://localhost:8888/servlet/GetDSUsingJNDI

How to correct close database connection after report generation

Hello
I have problem a with alive database connection after report creation and report closing. How to properly to close connection to database?
Best regards
Edited by: punkers84 on Jun 17, 2011 10:38 AM

that's what I am doing... after viewing the report, I call the close method on the window closing event of the container window. but the connection is still open. I had a lot of other issues with my jdbc driver but after downgrading to an older version those issues are resolved.Only this one is still there! Is there any other way to close the connection (like using dbcontroller or etc.)?

Database connection pooling with weblogic 8.1.

Hai All,
I am new to weblogic database connection pooling.
I am using Weblogic8.1 and want to use connection pooling to get a jdbc connection. my database server is Oracle 8.1.7.
Things which i have done using the weblogic admin console.
I have created a Jdbc connection pool named myconnectionpool.
I have created a datasource named mydatasource.
and named the JNDI as myjndi.
Is the above process correct to create the connection pool in the weblogic8.1.
I am not aware of the java code to get the database connection object from the connection pool which i have created.
can any one please let me know the java code to get the connection from the pool.
Any help is appreciated
Thanks in advance
pooja.

Hai
I have tried using the code u have mentioned but it returned me
an error which is below.
C:\javaexamples\Javaprograms\JDBC>java jdbcexampleconnectionpool
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
I have added the following lines code, which i read in some weblogic documentation. The code i added is below and it worked fine.
ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL,"t3://localhost:7001");
Context ctx = new InitialContext(ht);I am not sure what the above code does.
Can anyone let me know what does the above code do.
Thanks a lot and i appreciate ur help,
Pooja.

Can i use single database connection in a hole java application?

can i use single database connection in a hole java application?.I have so many forms to use database connection.

Theoretically you can. Not only theoretically. I've seen lots of application which only uses one database connection (they were using, oracle or mysql)
The first reply given here assumed that the answer to
your question depends only on the design of your
application. That is not true.Yes it's true. Nothing in the original questions says that you aren't allowed to open or close the single connection that you have. It's looks more like the OP is interested in sharing a connection (i.e having a singleton or a connection pool with only one connection)
It does also depend on the behaviour of the database
in the background.
Most databases have a time out for connections that
are idle Not a problem. Most implementations of connection pools and applications which keeps a connection open have a timer which calls e.g. select * from dual (if you are using oracle) when the connection has been idle for X minutes.
(some, like db2 on z/OS, even cancel
connections, that are not idle, if they are open a
certain amount of time or have reached a given limit
of cpu seconds.)You would also have that problem if you had a connection pool with several connections.
In essence: If you have no control over the time
your application runs (and therefore your connection
is open) or over type or the configuration of the
database you are accessing, you can't do it.See above.
The closest thing to what you want would be using
PooledConnections, iif those are supported for the
database you want to access.Not true.

Bc4j.xcfg, database connections and deploying ADF apps to oc4j

I'm trying to understand how to enable custom database connections on a JDeveloper ADF application deployed to a stand-alone instance of OC4J.
All entity objects were created as ADF Business Components.
I looks like the db connection information used by the application is stored in a file named "bc4j.xcfg".
How would I change the database connection information between different environments, changing the server, port and password information from an OC4J instance?
I'd like to use an OC4J defined data-sources.xml file, but am looking for the simplest approach for now.

Tomato tomaato, call it what you will, we now have to spend time (money) figuring out how to change from using the recommended use of a "connection" from Oracle tutorials and in Oracle Press books.
Plus, neither I nor our client can get JDeveloper ADF 10.1.3 to work on OAS 10.1.2.
Oracle has been of little help, other than stating to follow documentation. We followed the documentation at least a dozen times and on three different install of OAS 10.1.2.
Why doesn't JDeveloper have a check-box or button that reconfigures the application to run on 10.1.2 (J2EE 1.3), there is a check-box to change JDK versions (1.4)? This is suspect to me.
We are going to be speaking with the client this week, and have to state the ADF application works, but NOT on OAS 10.1.2.
Does ADF work on OAS 10.1.3, absolutely, but the client is in 10.1.2 and can not upgrade at this time.
I've read in blogs where lots of developers have the same issues without resolution and Oracle should just come out and state that 10.1.3 does not work on 10.1.2.
So my experience has been a mixed bag with ADF, both in terms of the software and customer support from Oracle.

How can I get Connection(Database Connection)on my backing bean

hello guys!
How can I get the Database Connection on my managed bean?
I want to use this connection for my reports.
thanks a lot!
alvin

Alvin,
You can access the data provider through ADF the binding. The data provider represents the business service you use. Once you have a handle to this you can get the connection.
You don't mention the business service, so I cannot help you more than this. If it is ADF BC, have a look at http://download.oracle.com/docs/html/B25947_01/toc.htm and the stored procedure section. Steve Muench explains a trick to access the "real" JDBC connect used by ADF BC

Make use of established database connection

From within an application in the Application Navigation, I have successfully established a connection to a database which is on another host machine. The steps are:
right-click on the name of the application > select New > Database Tier > Database Connection > Connection Name ....
After the connection is done, I am able to see the tables, etc. in the Connection Navigation, i.e., the connection was successful.
Under the same application, I created a web project and in the project I am writing a servlet. I figure I can make use of the established connection as described above, to create sql statement object? But I do not know how. For example, I named that connection SbConnection, and tried the statements:
Statment stmt = null;
stmt = SbConnection.createStatement();
But it does not work out. I am trying this because the classical way of
Class.forname(....).newInstance();
Connection conn = DriverManager.getConnection(......);
does not work no matter how I tried.
I am just starting in doing web application, servlet and JSP etc. and would appreciate a lot for any help.

Fantastic, dvohra! It works out! Thanks a lot for the know-how!
Next I am going to dig out something to read about JNDI and DataSource type of connection. But the part of editing the web.xml is magic and myth to me. Any suggested books or web sites for reading? (After know-how is know-why and know what I am doing.) Many thanks!

Problem With Midlet Database Connectivity

Hi, I am into an application which reures database connectivity.I want to connect to Ms Access as backend with JDBC support.Ive searched a lot but found RMS as the only answer.I will be very thankful if some one can send me a code snippet or some link to an article which shows the trail to my problem.

You can't have an MS Access database on the phone itself. And even if you can (on an MS SmartPhone maybe?), MIDP has no way to connect to it.
But if you need to connect to a database that's hosted on a server, then what you have to do is set up a regular web server (using ASP, Servlets, PHP, whatever you fancy), and communicate with this server using the General Connection Framework (that's the javax.microedition.io.* classes). The web server, instead of outputting data in HTML format, can output the data in a format you design and know how to read and parse on your MIDlet (for example, for a simple application a comma separated string will do, for something more complicated maybe you want to use XML, or even develop your own binary format).
If you want the data to be stored on the client then I'm afraid you're stuck with the RMS.

Help! My database connection from BMP Entity bean dies after a while!!!

Hi all!
I posted a related post about this lately How do I use connection pooling from BMP Entity Beans in OC4J 10.1.2? but it didn't solve my problems.
I have some entity beans coded with BMP, so I handle all database stuff myself. I have set up datasources.xml like this:
    <data-source
        class="com.evermind.sql.DriverManagerDataSource"
        name="OracleDS"
        location="jdbc/OracleCoreDS"
        xa-location="jdbc/xa/OracleXADS"
        ejb-location="jdbc/OracleDS"
        connection-driver="oracle.jdbc.driver.OracleDriver"
        username="scott"
        password="tiger"
        url="jdbc:oracle:thin:@//URL TO DB:SID"
        inactivity-timeout="30"
        min-connections="10"
        max-connections="50"
    />All JNDI connection lookup is done through the ejb-location as I should. I have been through all my try {} catch {} finally {} blocks, so ensure that I close all objects after use.
After a few hours of inactivity, my program dies. I have inserted a lot of debug statements (System.out.println()), and it seems like the program hangs when it's trying to execute a PreparedStatement.
I.e. it dies when I do ps.ExecuteQuery in the code below (NOTE: to make things easier to read, I have stripped out all error handling here):
    Context ic = new InitialContext();
    DataSource ds = (DataSource)ic.lookup("jdbc/OracleDS");
    c = ds.getConnection();
    System.out.println("DEBUG: Got database connection.");
    PreparedStatement ps = c.prepareStatement("SELECT foobar FROM footable WHERE foo=?");
    System.out.println("DEBUG: Prepared SQL statement.");
    ps.setString(1,"foo");
    ResultSet rs = ps.executeQuery();
    // Close all objects (rs, ps, c) here.My database is on another physical server, so I wonder if this is caused by an unstable network, or?
Please help!

Hi again!
Sorry for the delay, but I have been busy lately.
Anyway: Our application server is 10.1.2, so I don't think patch 4307303 is relevant here. Database server is Oracle 9.2.0.6. Everything runs on Linux (of course) ;-).
Here's a thread dump:

Jdeveloper Crashing When Opening MDB Database Connection

Hello,
I created a database connection to one of the local access mdb file using jdbc-odbc connection type.
When I tried to view the tables or when I try to create a toplink connection using the same connection I created to access mdb file, my Jdeveloper is crashing.
Any what could be the reason.
My Jdeveloper version:
10.1.3.4.0
Regards

Time marches forward and I have no disagreement with any of the Weblogic decisions. The reality is though that we still do not have a clear answer from Oracle (although our clients sales folks are working on it) as to whether the client will have to pay to "upgrade" their Oracle Application Server (Enterprise) licenses to get the WebLogic server necessary to run the applications created by the final Production JDeveloper11g. If it costs money then it requires budgeting and that all takes a lot of time.
We have a fairly rich application already developed and we cannot port it to Weblogic until the licensing issues are resolved. Until that happens it will have to continue to run on the OC4J container.
BUT ... I consider this "not a problem" with respect to TP4 not running on Vista 64-bit as long as the final release JDeveloper 11g does. I'll just have to work in my VPC hosted XP Client until our clients get their licensing issues sorted out with Oracle.

Timeout: Tuxedo kills the service but not the database connection

Hi all,
I am experiencing some performance problems on my system due an efficient SQL and a Tuxedo improper timeout handling.
A service is using a "problematic" SQL (we will tune it but it's not the main problem). After 60 seconds from the execution, Tuxido kills the services for a timeout.
At this point I would like Tuxedo to notify DB2 database as well in order to stop processing the SQL. Instead the SQL continues running on the database (also if the service is killed) and this produce a gradual slow down of the performances.
In the UBBCONFIG, we are using a service configuration like the following timeout configuration:
.RESOURCES
SCANUINIT 5
SANITYSCAN 6
BLOCKTIME 12
.SERVICES
DEFAULT: SVCTIMEOUT=45
service1 SVCTIMEOUT=60 TRANTIME=60
service2 SVCTIMEOUT=60 TRANTIME=60
Note: not all the services are listed in the .SERVICES section and we are using the default NOTIFY as well as an OPENINFO.
Can you please help me in finding a configuration to kill both the services and the database?
Thanks in advance,
Benedetto

Hi Benedetto.
First of all, Tuxedo doesn't kill services, it kills servers. Your UBBCONFIG file specifies three timeouts, BLOCKTIME, SVCTIMEOUT, and TRANTIME.
BLOCKTIME specifies how long a Tuxedo API that needs a response will wait for that response. If the response isn't received in that period of time, Tuxedo will return TPETIME to the caller. As with any failure, if the request was part of a transaction, the transaction is marked rollback only. Note, this timeout does not affect the request, whether sitting in a server's IPC queue or currently executing in a server.
SVCTIMEOUT is a much more severe timeout and determines how long Tuxedo will allow a service implementation to execute. If a service implementation doesn't reply within the SVCTIMEOUT period, Tuxedo will issue an OS level KILL request to kill the process. If the server is marked restartable, Tuxedo will then try to restart the server assuming none of the restart limits have been reached. Killing the server causes the request to be lost within the server so the caller will stay blocked until BLOCKTIME is reached at which point the above actions will take place.
TRANTIME is the amount of time Tuxedo allows a transaction to remain active and viable. When this period expires, Tuxedo will mark the transaction as timed out with the only option being rollback. As well, Tuxedo aborts any API requests that would normally cause messaging to occur, i.e., making a tpcall() within a timed out transaction will fail without any attempt to call the service.
So in your case, the issue is partially that you have the values of your timeouts in somewhat reverse order. Typically we see BLOCKTIME being the smallest value, with TRANTIME typically larger than BLOCKTIME, and SVCTIMEOUT larger even still, although there are good reasons for exceptions to this guideline. Part of the reasoning behind this is that killing a server is a significant thing and its usually best to try and let the server complete whatever its doing, if if the work has been timed out either due to BLOCKTIME or TRANTIME, since the cost of killing and restarting a server is significant.
Tuxedo will notify the database of the transaction status when the application finally issues a tpcommit() or a tpabort() request, but not until then. Although, if SVCTIMEOUT is hit, then killing the server should cause the database connection to be lot.
If you could describe the behavior you are seeing and the relevant portions of your ULOG we can try to make some sense of what is happening.

Database connectivity to business objects

Post Author: kshatri
CA Forum: Administration
Hi All,
I am new to for my first project, having good knowledge about BO but my only concern is with the first day target.
As a new team mate memeber what are my roles and responsibilites to be done.
How to interact with the Administrator to get my database connectivity and then how to implement the path provided by the admin people to get my database activate and then to connect it to the business objects.
So again i am requesting you all if you any one among you, who has already gone through this situation could help and make to understand how to connect the database to business objects.
And how to present ourslef in a new environment.
Thanks,
Anu.

CA Forum: Administration
Anu,
This is one of those forum threads that could last all year with comments, tips, and criticisms. If you have a lot of knowledge about BusObjects, then you are nearly half way there. In my experience, the biggest road block to success is communication and team cohesiveness. If everyone on the project are not communicating with each other then everything is going to fail. What do I mean about communication? It's hard to pin down, but when I see it I'll know it's there (smile). For starters it's having a good plan that everyone can work from. An underlying theme in communications is also trust. The folks who hand out the userids and passwords must be able to trust the folks who are receiving the privileges. If the administrator must give you read/write access to his or her database and they don't "know" you, then this is an uphill battle. Many administrators do not understand middleware such as BusObjects, they are more familiar with things like Access, and such -- the more simpler applications. When you try throwing terms around like business intelligence, single-sign on, multiple queries, data providers, meta data, report viewer, etc, etc their heads start to spin and they want you OUT of their sight. All of these concepts must be introduced gently and in an appropriate setting. The admins must get familiar and comfortable with your tools before you can make headway. So that is what I mean by communication, in this case laterally. You must also communicate upwards (the C-level folks), and downward, the users. Like I said, folks could add to this thread infinitum, and I would invite other as such, but here are some things to think about as you move forward. The best teacher is experience, but who has time for that?
