what will be the host name, port number??
can any one explain

The host name is the name or IP address of the machine running Oracle.
The port number is the port the DBMS is listening on for connection requests.

Cannot create connection pool with weblogic jDriver XA for oracle

Hi everybody,
we have serious problems configuring the weblogic jDriver for Oracle with support
for distributed transactions.
Everything works fine with the non-XA driver.
We tried the suggestions given here before like setting the environment variable
ORACLE_SID. However, this does not change the errors we get. We use Weblgic Server
6.1 SP2 with oracle 8.1.7 (client and server) under Windows NT.
When attempting to create the connection pool, we get the following exception:
Starting Loading jDriver/Oracle .....
<14.05.2002 15:48:30 CEST> <Error> <JDBC> <Cannot startup connection pool "DiplPool"
weblogic.common.ResourceException: java.sql.SQLException: open failed for XAResource
'DiplPool' with error XAER_RMERR : A resource manager error has occured in the transaction

We suspect that we do not set the properties of the connection pool correctly. The
declaration of the pool in config.xml looks something like the following:
<JDBCConnectionPool CapacityIncrement="1" DriverName="weblogic.jdbc.oci.xa.XADataSource"
InitialCapacity="10" MaxCapacity="15" Name="DiplPool"
Properties="user=scott;password=tiger;url=jdbc:weblogic:oracle:srlaptop_aidenbach.muc.sdm-research.de;dataSourceName=DiplPool"
Targets="Marvin" TestTableName="privcust" URL="jdbc:weblogic:oracle:srlaptop_aidenbach.muc.sdm-research.de"/>
Are there any known issues with the XA driver and the versions of oracle and Weblogic
we use? Can someone tell us how exactly we have to define the connection pool or
provide an example?
Any help would be greatly appreciated.
Best regards,
Michael

Hi Michael
Here is an example connection pool tag,
<JDBCConnectionPool
Name="oraXAPool"
Targets="myserver"
DriverName="weblogic.jdbc.oci.xa.XADataSource"
InitialCapacity="1"
MaxCapacity="10"
CapacityIncrement="2"
Properties="user=scott;password=tiger;server=ORCL"
/>
Ensure that the server=ORCL is replaced by server=<what ever the Alias is
defined in TNSNAMES.ORA file>
You dont have to specify the URL for this.

How to use Connection Pool in ADF ear file creaion from jDev 10.1.3

Hi,
We are developing big application in ADF with 10 different modules. We are creating ear file with data source setting.
How to use connection pool while creating ear file from jDev. Connection pool is alreday created in Application Server 10g.
What all the setting we need do to make use of connection pool while creating ear file jDev.
Thanks

User,
If you are using ADF Business Components, you can right-click each application module, select "configurations" and edit the configuration you are using. On the initial page of the configuration dialog, you can specify to use either a JDBC URL or a Datasource - you just need to choose Datasource and then provide the name by which to access it.

How to retain connection pool resource while exporting the application war

hello,
lately i have figured out how to use connection pooling. now i have another issue.
i have to export the application war file to a remote server for deployment. i cant configure the server.xml file there due to restrictions. Now is there any way that i can retain the connection pooling with all JNDI resources while exporting the war file. what all things would i have to do. i am using tomcat 4.1 and the remote server too have the same appliaction server running.
is this possible?
thanks in advance

Hi,
you might have the problem in creating WAR files.
lease check that first.
thanks,
nvseenuNo, the problem is that you shouldn't be modifying the server.xml
The proper, portable way to do it is to create a context.xml file and put it in the META-INF directory of your WAR file. This contains your Resource definition and JDBC connection parameters. Everything's portable that way.
I know this works on Tomcat 5.x.
It can also work with Tomcat 4.1.x, but the way I've done it is to put the context.xml into a file whose name matches my WAR file (e.g, foo.war and foo.xml), placing both in the /webapps directory. Tomcat 4.1.x picks it up that way.
It would be worth an experiment to see if Tomcat 4.1.x picks up the context from /META-INF, because that way your WAR file is 100% portable.
This is precisely the reason why I advise people not to edit the server.xml. You don't always have the option to do so.

2. Configuriing the jndi in Weblogic server
weblogic.common.ResourceException: Could not create pool connection. The DBMS driver exception was: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
The Connection descriptor used by the client was:
localhost:1521:SERVICENAME

Problem
database url is generated based on SID
eg: jdbc:oracle:thin:@localhost:1521:SID
Solution
(generate seperate url for SERVICE NAME)
jdbc:oracle:thin:@localhost:1521/SERVICENAME
------------------------

It is so clear: host not found error for network connection and the other SID servcie name not found means your oracle instance name is not up. check with srvctl status for given servcie name or node, else check CRS_Stat -t if you are using RAC.

Problem when getting resultset when using connection pooling in weblogic

Hello,
I am new to database connection pooling. I am using weblogic server, Java 1.6, MySql database. I have done connection pooling in weblogic server. The problem arise when I try to run select query I cannot fetch data in ResultSet. For insert it works fine...
import java.io.Serializable;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;
public class DatabaseToText implements Serializable {
public DatabaseToText() {
super();
// TODO Auto-generated constructor stub
public static void main(String[] args) {
Connection conn;
Statement stmt;
ResultSet rs;
String str1, str2;
List l1 = new ArrayList();
try {
System.out.println("in try block");
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
prop.put(Context.PROVIDER_URL, "t3://localhost:7001");
System.out.println("properties are set ");
Context ctx = new InitialContext(prop);
System.out.println("b4 lookup(mysqljndi)");
Object obj = ctx.lookup("mysqljndi"); // java:comp/env/CPDS
System.out.println("afta lookup(mysqljndi)");
DataSource ds = (DataSource) obj;
conn = ds.getConnection();
stmt = conn.createStatement();
String query = "select * from logindb.userregister";
System.out.println("query is = " + query);
rs = stmt.executeQuery(query);
System.out.println("size of rs is :: " + rs.getFetchSize());
if (rs != null) {
while (rs.next()) {
str1 = rs.getString(0);
str2 = rs.getString(1);
System.out.println("username is :: " + str1 + "password is : " + str2);
} else {
System.out.println("no values get fetched");
ctx.close();
} catch (Exception e) {
e.printStackTrace();
OUTPUT IN CONSOLE
in try block
properties are set
b4 lookup(mysqljndi)
afta lookup(mysqljndi)
query is = select * from logindb.userregister
size of rs is :: 0
java.sql.SQLException: weblogic.rmi.extensions.RemoteRuntimeException: Unexpected Exception - with nested exception:

Record is getting inserted but when i use select query i cannot get the output...

Unable to create connection pool on weblogic startup

Hi, I have a problem currently with the connection pool of weblogic 8.1 not being able to be created on a scheduled restart daily.
The weblogic server is restarted daily at 6am. However, the oracle database is shut down for maintenance daily till 7am before it is up again. It is not possible to shift either timings of restarting weblogic and oracle.
Is there any script or option settings in weblogic to reconnect the connection pool after 7am daily without restarting the weblogic instance?
Please help. Thanks.

Please help. Thanks.You can use the weblogic.Admin command line program to create, destroy, disable, or enable pools
in a running server. However, the easiest thing to do is to define your pool to have an initial
capacity of zero, so it is allowed to be created at startup, without needing to make any connections.
Then it will self-populate as needed when application load starts, if/when the DBMS is available.

You can use WLST or weblogic.Admin command. WLST is the recommended appraoch. Here are a few links for both of the above:
