Connection pool setting error

I tried overwriting a my current repository with a new repository but I'm getting error.
The new rpd file is from another system with different datasource and user name (connection pool). Anyway to get this working?
How to change the user name to that of the current system?

You could have merged the repositories instead of overwriting. Now it is pretty difficult to tell what is what and what is where. Any specific error you get? But before going there, is there any reason why you overwrote the existing repository? Before overwriting you need to be very careful that the new repository is a superset of your older one.
Thanks,

Sun Java Systems Application Server 9 connection-pool ping error

Hi folks, I tried creating a javax.sql.DataSource MSSQL database connection pool with the jdts type 4 driver I got from sourceforge, and each ping operation I tried gave me the following error message:
Operation 'pingConnectionPool' failed in 'resources' Config MBean.
Target exception message: No PasswordCredential found.
My connection properties are:
user = sa
port = 1433
databaseName = FlyMyWayDB
serverName = digitanx-chalu
What does this exception mean, what are the possible causes, and how do I go about resolving it.
I will really appreciate any help, thanks.

As long as the JDBC Driver (jar file) for the connection pool(s) you want to create are in the app server's lib directory, you shouldn't have a problem creating both those and the JDBC Resources from the admin console (web app). So far, I am able to bundle my connection pools and resource connections inside my ejb module under "Server Resources" within my enterprise (.ear) application in Netbeans 5.5. When I deploy it, the whole thing works pretty sweet. I haven't gotten to the stage where I will want to migrate the jee application to my dedicated server yet, but I suspect that if my dedicated (remote) app server doesn't want to play nice with my netbeans when I try and set it up as a new server under my "Server Manager", then I'll likely try to simply deploy the .ear file from within the admin console, using the "browse" (for .ear) option (likely the better/preferred practice for production anyhow). Thanks for the dukes! My very first ones ever!

JDC Connection Pooling compilation error .... Please help

I am trying to implement the JDC Connection pooling classes that I downloaded from this site. The 3 classes are:
JDCConnection.java
JDCConnectionDriver.java
JDCConnectionPool.java
I am having trouble compiling the JDCConnection.java class. The error that is coming up is this:
JDCConnection.java:7: pool.JDCConnection should be declared abstract; it does not define createStatement(int,int) in pool.JDCConnection
public class JDCConnection implements Connection {
If I change the class to an abstract one, then I get an error indicating that one of the other classes cannot call a "new" instance of it because it is abstract.
I have all the classes in a package called pool and YES I have set all the classpaths so that javac knows where to find it. I have posted the JDCConnection.java class below so you can see it. I have not modified it from how I got it.
package pool;

Thanks

I didn't realize that I was extending an abstract class. Could you point out to me where it is in the code that I am doing this. Also, you tell me to "code this method", but I am not sure how to do that.
Does that mean that I need to more specifically define the createStatement method like this:
public java.sql.Statement createStatement(int resultSetType,
int resultSetConcurrency)
instead of:
public Statement createStatement()
like it is now.
Please keep in mind that I would rather not declare the whole JDCConnection class as abstract since that means that I can't create a new instance of it from another class .... or am I wrong in my thinking. I really do appreciated any help anyone can give me.
Thanks

Anyone successfully set up connection pool in s1as with ms sql server 2000?

As subject. Since I have seen a lot of posts about the NoSuchMethodException issue with various dbms providers, and the only "official information" I found thru different forums, google, different sun/javasoft sites and forums are this:
http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsunone%2F8172&zone_32=NoSuchMethodException&wholewords=on
Which is wonderfully vague and provide not-so-much useful information...
As for the information and suggestion posted by other forum members, most or all of them have experience with setting up Oracle, DB2, mySQL, etc., not aimed for MS SQL Server 2000 (you may think, I am just asking for it running MS SQL server with Java... oh well, not my choice)
I still haven't seen any positive feedbacks on how this exception was caused and how to resolve it. I have literally exhausted all leads on how to fix this issue, so right now I'm only interested to know whether anyone in the forum actually have a successful connection pool set up with MS SQL server 2000.
My platform:
w2k sp3
SunOne app server, update1, JDK 1.4.1
latest MS SQL 2000 JDBC driver
This fails with the NoSuchMethodException error:
try {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("test_db");
con = ds.getConnection();
System.out.println( "con is created -> " + con );
} catch (Exception ex) {
System.out.println( "failed -> " + ex.getMessage() );
This works just fine:
try {
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con = DriverManager.getConnection("jdbc:microsoft:sqlserver://xxx.xxx.xxx.xxx:1433;DatabaseName=testdb;SelectMethod=cursor", "username", "password");
System.out.println( "con is created -> " + con );
} catch (Exception ex) {
System.out.println( "failed is fucked -> " + ex.getMessage() );

3) How can I test my connection pool have problem or not ? is

Error in creating Connection Pool using Oracle Thin Driver

Hi,
I am trying to create a connection pool in WS 5.1 with sp #6 using Oracle Thin Driver (oracle.jdbc.driver.OracleDriver) on a Sun box. But I am able to create the pool using weblogic.jdbc.oci.Driver. I get an DBMS Driver exception when I use thin driver. I have LD library path and weblogic class path set correctly. WL shows the following exception :

Hi Ramu,
Please post your connection pool setting here. You might have missed some

Regarding connection pooling in java mail

Hi,
Im implementing enterprise application which has ability of sending/receiving emails. Im using java mail API 14.3. I have implemented the application level connection pooling which keep track of open folders, perform the time-out and other tasks. The connection pooling setting of IMAPStore is default setting. When we run our application in high load we get StoreClosedExcepton (Socket closed exception). My assumption is that when we perform some operation on folder, java mail also sends the noop command for store connection so there is no chance of store getting timeout.
Is there anything wrong in my understanding?

JavaMail does not do anything to keep the connection "alive". Servers are free to close
connections that have been unused for too long (usually 30 minutes). If you need to
keep the connection alive, you'll need to do some operation periodically, such as checking
the number of messages in the folder. Even that doesn't guard against server or network
failures, of course, so you always have to be prepared for a StoreClosedException or
FolderClosedException.

Read data using 2 diff connection pool for same DB folder in physical layer

Hi All,
i am using two connection pool which have different dsn connection information (both are directed to different database name or database server)..
so if i view the data of any table, a prompt will come asking for the connection pool, so how do i automize it....?
how do i set the different connection pool for different tables?
please let me know if u need further informtaion to understand my problem..
thnx...

thnx Stijn..
yupe that i know...
actually i have total of around 300 tables in physical layer (in both the schemas..) , around 12 fact and 100 dimension tables in bmm and same in the presentation layer...
so i think u can guess how many joins and other stuff, i have made in my bmm layer..
if now i will start modifying all this it will take lot of time...
i am just wondering that there is no alternative for this...
as when i check my data from the physical layer then a prompt ask for the connection pool (i have already made two connection pool..) so there could be some alternative way to automize the default connection pool setting for the tables/schemas folders in case if more than one connection pool exits under the same database in the physical layer...
isn't it?
thnx again..

'timezone region not found' while updating connection pool

Hi Experts,
We have upgraded our weblogic server from 10.3.3.0(11.1.1.3.0) to 10.3.6.0(11.1.1.6.0)
All the data sources and connection pools were created in the previous version(11.1.1.3.0) and it worked fine.
After the upgrade has done, we tried to run a BPEL web service which is using a database connection to get some data.
Then the below error has thrown out in EM.
*<part name="summary">*
*<summary>Exception occured when binding was invoked.

What can do??
Thanks in advance....

Hi Joe,
Thanks for the reply...
But it seems answers are given related to 'Application Express Listener'.
The thing is we got this issue once we upgrade the middleware tier. We cannot do anything on database side. (Remote database)
The solution should be in middleware, Weblogic server side.
Our live environment still in the 10.3.3.0 version. It works fine..
any suggestions ???
Thanks....

Help please: What gets pinged - Connection Pool

I have a connection pool set up and can "ping" it, but I cannot seem to use it in my application.
What exactly gets "pinged" (what address)?
For example, my setup looks like this:
Data Source Class Name - net.sourceforge.jtds.jdbcx.JtdsDataSource
Resource Type - javax.sql.XADataSource
serverName - localhost
port - 1433
datasourceName - jdbc/testSqlServerDatasource
databaseName - testdatabase
Under the connection pools in the Application Server Admin Console, I can "ping" this connection.
When I go out to a DOS prompt and try to ping, I cannot. What I tried was:
ping localhost:1433/jdbc/testSqlServerDatasource
ping localhost:1433/testSqlServerDatasource
ping localhost/testSqlServerDatasource
What exactly should I be able to "ping"?
Note too that I have a JDBC Resource set up (also using the Admin Console) with a JNDI Name of testSqlServerDatasource.
Thanks.

The Ping in connection pool actualy tries to establish the connection with the database for which the configuration is provided in the Connection Pool page. The ping on DOS command is not same with what you actualy do in Connection Pool page. The DOS ping "helps in determining TCP/IP Networks IP address as well as determine issues with the network and assists in resolving them".

Principals for connection pools

We are using a dbms realm for our application on a Bea WeblogicServer
5.1 on Solaris
7.
It seems that it is not possible to use a group as principal for
a connection pool in the
weblogic.properties file. This results in a SecurityException when
a user which is a
member of the corresponding group tries to get a connection from
the connection pool.
Does anybody have similar problems or even better a solution or
explanation for this
problem?

probably not your problem, but groupnames and usernames should
be unique in weblogic, so if you happen to have a user with the
same name as the group you are trying to use, it would confuse
the server.

I've been looking at different documents on dev2dev, but being new to the

way to say it.
