Database connection from ALSB

Hi all,
i'm trying to connect to DB from ALSB using execute-sql(). i have created the datasource in the process construction stage, but ALSB fails to locate the datasource during testing. is it mandatory to create the required datasources on domain creation itself?
Also what kind of operations are supported by execute-sql().
Thanks,
PreethaV.

You can create the datasource at any time.
Usually execute-sql() can only do select statements but there is a way to run stored procedures which can do updates. I have not tried this.

Problem in getting the database connection from a connection pool

Hai All,
I am facing a problem in getting the database connection from a connection pool created on weblogic server 8.1.
I am using the Oracle database 8.1.7.
I have configured my connection pool, datasource and JNDI in weblogic.
In my java program i have the following code to retrieve the connection.
import java.sql.*;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
class jdbcshp1 {
    public static void main(String[] args) {
     Connection connection = null;
     try {
           Hashtable ht = new Hashtable();
           ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); // Wanna get rid of this.
           ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); // wanna get rid of this.
           // Get a context for the JNDI look up
           Context ctx = new InitialContext(ht);
        javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("myjndi1");
          //Create a connection object
          connection = ds.getConnection();
     The above code is working fine but, the two ht.put statements are creating problem.
The problem is, after converting the application into WAR file it can be deployed
on any machine or different port on same machine. My application fails if its deployed on
weglogicserver which is at different port.
Is there any way that i can get rid of those ht.put statements or any other way to solve the problem.
any help is appreciated.
Thanks in advance
Pooja.

Hai All,
Firstly, thanks for ur reply.
Even i have seen some code which uses context constructor with out any parameter and works fine.
i dont understand why its not working for my code.
When i remove those ht.put code and use context constructor with out any parameter, it giving an error.
Context ctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("ocjndi");
connection = ds.getConnection();The error is as follows:
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
the above error is forcing me to include those code but if the port number is changed the code will not work. Plz let meknow if some setting have to be made.
I appreciate all ur valuable help.
Thanks once again.
Pooja.

Error While creating new database connection from HFM workspace

Hi,
We have recently installed HFM and was trying to create database connection from database connection manager in HFM workspace.
I am getting below error:

Steps to change universe database connection from SQL server to Oracle 10

Hi,
we are moving from sql server to Oracle 10.Please let me know the steps and various parameters I should consider while changing universe database connection from SQL server to Oracle 10.
Following are the steps which I assumed :
1.     create a new Oracle database connection or edit the existing connection to point to Oracle server
2.     Need to check sql for each object, having integrity check for universe will solve the purpose of parsing each object
3.     Exporting the universe after integrity check
4.     Report data testing
Let me know if I miss on any steps.Also what all factors I need to consider while moving to Oracle for eg: what @ custom sql,what @ table names,what @ LOV etc.
Kindly reply

Thanks Abhijeet and Shreyash,
I will follow the steps you have suggested.
Actually I was searching for this on net and got to know that with Oracle database connection,theres lot of stuff needs to take care of in terms of custom sql and LOV and in our case,we have lot of custom sql for each object in the universe so just wanted to confirm.
I will do the changes and let you guys know in case theres any isuue specifically to Oracle.

Why does it take over 2 minutes to get a database connection from the DataSource?

Hello,
It is taking over 2 minutes for my application to get a connection from a registered DataSource in iAS 6.0 sp4 on Solaris. The proper results are returned it just takes 2 minutes to establish the connection. The DataSource is an Oracle 9i database. I have the 9i drivers in the classpath. I also have a registered datasource that is an Oracle 8 database and have no problems establishing a connection quickly to that database. As an aside I have setup this application on JBOSS and both datasource's return a connection very quickly. If anyone has any ideas about what might be going on please respond. This issue is holding up a production release.
Here is the code:
try {
log.debug("getting a new initial context");
ctx = new InitialContext();
ds = (DataSource) ctx.lookup(bundle.getString("IW_DATASOURCE"));
log.debug("after looking up datasource from initial context");
} catch (NamingException e) {
log.error(e);
throw new FinstarException
(bundle.getString("E-0001"));
try {
log.debug("about to get connection");
conn = ds.getConnection();
log.debug("after getting connection");
Produces this in the logs:
2002-05-29 08:55:12,859 DEBUG org.mitre.mii.project.finstar.FinancialSummary - about to get connection
2002-05-29 08:57:24,963 DEBUG org.mitre.mii.project.finstar.FinancialSummary - after getting connection
Here is the datasource registration file:
<ias-resource>
<resource>
<jndi-name>jdbc/pdc/IWDataSource</jndi-name>
<jdbc>
<database-url>jdbc:oracle:thin:@xxx.xxx.org:1521:acisdb</database-url>
<datasource>jdbc/pdc/IWDataSource</datasource>
<username>XXXXX</username>
<password>XXXXX</password>
<driver-type>OracleThinDriver</driver-type>
</jdbc>
</resource>
</ias-resource>

Have you tried to eliminate everything extraneous. In other words, do you experience the same delays with a simple Java program (no lookups, JNDI) that loads the drivermanager and creates a connection.
Do you have access to a traciong JVM or some program that captures run-time execution timing information? Even without the source, this will tell you the specific class::methos where time is spent so you can better determine where the delay is ocurring.

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) ;-).

How to get total number of Database connections from Java code

Hi,
I am using Myql4.1.12.
I am conncting to mysql through Java.
I want to know how many active database connections were running at a specific time. Is it possible?
Can you please help me.
Thanks in advance.

Seems like this would be a question for MySql, not for Java. And if it's possible you'd run some MySql utility to do that, not code it in a Java app.

Error in Getting Database Connection from datasource

How to Database Connection from Windows 8.1

Hi, I am a newbee with SQL from Windows Azure.
Is it possible to see the Azure SQL server in my Windows Explorer browser? Or how to connect to this newly created database from my application. I would like to store the database in the cloud..
I have installed on my local PC a administration software package. Also installed on another PC the sql express version of SQL.
But wanted to use the database from Azure instead of my on-premmis sql server.
Please can some help me out with this?
Regards,
Rense Prakken

Hello Rense,
There are many tutorials/online documentation available which can guide you as how to connect to a SQL Azure DB from your application. I'm providing you some basic as well as how to articles which you can go through.
http://azure.microsoft.com/en-us/documentation/articles/sql-database-get-started/
http://msdn.microsoft.com/en-us/library/azure/ee336282.aspx
http://azure.microsoft.com/en-us/documentation/articles/sql-database-dotnet-how-to-use/
http://azure.microsoft.com/en-us/documentation/articles/sql-database-manage-azure-ssms/
http://msdn.microsoft.com/en-us/library/azure/ee336243.aspx
http://msdn.microsoft.com/en-us/library/azure/ee621781.aspx
You also had a question if you can see the Azure SQL DB in your Windows Explorer. The answer to this question
is NO, but you can certainly see your Azure SQL Database in the Object Explorer in the SSMS (SQL Server Management Studio).
Hope this helps.
Thanks and regards...

Make sure your servlet code is just like the right way that you have it
