Help me in classpath settings/Connection Pooling

hello,
When i configured my connectionpool with
Sun Java Application Server Admin Console
i found this error:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Class name is wrong or classpath is not set for : com.microsoft.jdbcx.sqlserver.SQLServerDataSource
where do i need to change is there an error in the jvm classpath or
is it due to connection 2 the Server

Dear Customer,
As you can see, your pre-requisite checks are failing because you are not on supported OS version.
Please verify supported OS from SRSP guide (If you are on prior Siebel version 8.1.1.8) or Certification tab for all siebel versions from 8.1.1.9.
I hope it helps.
Best Regards,
Chetan

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".

Strange problem since changing some settings Connection Pool

Since changing the following settings in my connection pool, I have been seeing strange behavior with an application that has been deployed for over a year.
 
The settings I changed were the following:
 
Maximum Capacity: Changed from 25 to 100 
Statement Cache Size: Changed from 10 to 200 
Shrink Frequency: Changed from 900 to 300 
Connection Reserve Timeout: Changed from 10 to 5 
Maximum Waiting for Connection: Changed from 2147483647 to 50
 
I was wondering if anyone had any comments on these settings as well as any insight as to why I am seeing the results of a prepared statement
 
("select count(*) from event where event_id = ?" )
 
come back as 0 for the user that just created a record a few minutes before. At the same time another user can log in to the application and cause the same query to run and they get a count of 1 for the record the other user just created. Then if I restart Weblogic both users get a count of 1
 
Driver 9.0.2.0.0 
Weblogic 8.1.3.0

try
select * from v$session where lower(module) like 'jdbc%';if you don't find .... so... no connection from jdbc...
Because when jdbc pool ... start.... It should create connection ... hold on database.

Joseph,
The driver that I use comes from informix.
I've tried with JBuilder and no problem. JBuilder can connect to informixand
I can see the tables from JBuilder.
There's something wrong in the configuration with Weblogic.
Many thanks for your help.I understand that there's something wrong with the configuration with
weblogic,
but the problem is due to a mistake in the input you gave to the pool
definition,
and I want to solve that. Please show me the URL, driver name and properties
you give to JBuilder to make Informix connections. Also, show me the

Ok, I would like you to download Informix's driver from them, and
run one of their example programs, just to prove you can connect to
informix, using their driver, with no weblogic in the picture. We
have
to establish that, because that's all weblogic will be doing anyway.
Once
we know how to connect to informix via JDBC, we can do weblogic stuff.

Dear All,
Please help me How to create Connection pool for Reports and How to use in Reports.
Present i am using the report by passing parameter as P_JDBCPDS=username/password@databaseName. I thought this will not manage the coonection pool.
For all reports and every time i am passing userName/password, how to avoid this. Please help me.

2. How to use that Connection pool in the Reports.
Please help me.

HELP - DB2 v9 & App Server PE 9.0 - PING Connection Pool Failure - HELP

I've been playing around with Studio Creator and DB2 v9 without any issues.
So I figured I would installed App Server PE 9 and use this as my production server that I would deploy to from studio creator.
However, in my efforts to set up db2/v9 I have been trying to ping a connection pool without any luck. I get the following message:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: [sunm][DB2 JDBC Driver]Resource Limits Reached( ALLOCATE MEMORY FOR NEW SQLSTT FAILED ). Diagnostic Info: FUNCTION ID = 0049 , PROBE POINT = 0400 , TRACE POINT = 0030 , SUBCODE1 = 8B0F0000, SUBCODE2 = 78A68A98, SUBCODE3 = 00000000, ERROR MSG = Parser: Memory allocation error.
My datasource class name is com.sun.sql.jdbcx.db2.DB2DataSource.
And my resource type is javax.sql.datasource
I have copied smbase.jar, smdb2.jar and smutil.jar into c:\sun\appserver\lib
and I have all of the properties (serverName, portNumber, databaseName, user, password) created and set accordingly.
Any help would be greatly appreciated.

Here is how I got the DB2 Express-C and Sun PE 9.0 to work. ( at least base connectivity wise )
1. ) You have to have at least the DB2 Client installed on the system that will be communicating to the DB2 instance.
2.) The following jars will be needed ( depending on the driver type used) . db2java.zip, db2jcc.jar, and db2jcc_license_cu.jar and use them in the App Server ->JVM settings -> Path Settings -> Classpath Suffix
3.) The next setup is dependent on the Type driver you use
I used the Type 4 and this is the resource setup I used.
Connection Pool:
Name: DB2TestPool
Datasource Classname: com.ibm.db2.jcc.DB2SimpleDataSource
Resource Type: javax.sql.ConnectionPoolDataSource
Properties:
user: xxxxxx
password: xxxxxx
databaseName: TEST
serverName: <hostname of machine>
portnumber: 50000
driverType: 4
URL: jdbc:db2://<hostname>:<port>/<database>
JDBC Resource:
JNDI Name: jdbc/TEST
Pool Name: DB2TestPool
With this configuration I was able to ping the database as well as connect to create an entity bean from a table. This should give you a starting point.
I have yet to deploy my application, but should be doing that sometime today to verify that a connection can be made and used from within the application.

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.

Any help at all on this would be greatly appreciated.
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

Connection Pooling Help Needed

Greetings.
I am trying to get a database connection in Websphere 5.0 (running on Redhat Adv. Server) and my connection times are very, very slow. Below is the code to get the connection:
Properties parms = new Properties();
parms.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
// Create the Initial Naming Context
Context ctx = new InitialContext(parms);
DataSource ds = (DataSource) ctx.lookup("jdbc/customer");
Connection con = ds.getConnection();
Here is the setup for the database connection within the Websphere Admin Console to an Oracle 8i database:
Implementation: oracle.jdbc.pool.ConnectionPoolDataSource
JNDI Name: jdbc/customer
Statement Cache Size: 10
Data source helper class name: com.ibm.websphere.rsadapter.OracleDataStoreHelper
Connection Timeout: 1800
Maximum Connections: 30
Minimum Connections: 10
Reap Time: 180
Unused Timeout: 1800
Aged Timeout: 0
Purge Policy: Entire Pool
We CAN connect to the database. We CAN run SQL statements and stored procedures just fine. Everything with the database is working correctly. ok, so here is the problem... The statement: Connection con = ds.getConnection(); Takes a long time. 3+ seconds. Every time. No Matter what the load is. We need to get this time down significantly. It's killing our web services.
Using JMeter, We have tested it using a single thread and up to 50 concurrent threads and it all runs the same. 3+ seconds. We actually changed the code to create a database connection just using JDBC with no JNDI lookup and it runs at the same speed. It is almost as if the connection pool is not working correctly.
So then we looked to see if we were ever getting the same connection twice, but when we printed out the object references, it looks like the connection is a brand new connection EVERY time because the object references are different. Please see the partial log file I have included below.
Right now, our theory is that the connection pool is just getting us a new connection every time without reusing existing connections. We have played with all the settings on minimum connections, maximum connections, and everything else and nothing seems to help.
Thank you to anyone that might be able to help us.

I face a similar problem.
I'm using Sun Application Server 8.1 and my systems connects to Iplanet LDAP 5.1.
have my connection pool settings set to 100 max connections and a 3 minutes max wait time. But when i run my application, i found that the server never release any of my connection even when the connection expires from the pool. If i run a load test, I get a "Cannot allocation more connections" exception after a while.
If i run the same code in Sun App Server 6.1, it works fine. Is there some problem with Sun Application Server 8.1? Is there a patch for it?

I have been trying to get connection pooling working but i havent been successful yet. Please do help me make it happen.
I have posted my server.xml and web.xml from /conf/. They are not edited. I have also included the pages that I am currently ussing to connect to the database.
I need you to assist me with how I should edit the above.

Database Name : publications

Hi,
1- put your jdbc driver jar file in $CATALINA_HOME/common/lib (ex: C:\tomcat\common\lib )
2- Next, modify the web application deployment descriptor (/WEB-INF/web.xml) to declare the JNDI name under which you will look up preconfigured data source
take care of the ordering as below so resourc-ref tag is after taglib
<resource-ref>
<description>
Resource reference to a factory for java.sql.Connection
instances that may be used for talking to a particular
database that is configured in the server.xml file.
</description>
<res-ref-name>
jdbc/EmployeeDB
</res-ref-name>
<res-type>
javax.sql.DataSource
</res-type>
<res-auth>
Container
</res-auth>
</resource-ref>
3- add an element like this to the /META-INF/context.xml file in the web application. ( under ../webapps/mywebapplication/WEB-INF
<Context ...>
<Resource name="jdbc/EmployeeDB" auth="Container"
type="javax.sql.DataSource" username="hello" password="hello"
driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost/publications"
maxActive="8" maxIdle="4"/>
</Context>
4- code sample
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
DataSource ds = (DataSource)
envCtx.lookup("jdbc/EmployeeDB");
Connection conn = ds.getConnection();
... use this connection to access the database ...
conn.close();
The default data source support in Tomcat is based on the DBCP connection pool from the jakarta commons

Urgent...Help Needed.1. Helper Class 2. Connection Pool

Hello,
1. There are few helper classes which has to be
shared b/w session and entity beans. But it
seems,state of the object is not transfered to entity
bean though the class has implemented Serializable
interface. I have archived all the helper class and
copied to j2ee\home\lib directory. The same jar file
is made accessible to server via updating <library-
path> in j2ee/home/config/application.xml file.
2. How can i utilise connection pooling in oc4j. In data-sources.xml, i am using
"OracleConnectionPoolDataSource" class. But i feel that connection pool is not utilised coz server hangs in the middle of the retrieval.
The value of max-connections is 50.
We are actually migrating from Weblogic 5.1.0 to Oracle 9i AS. In weblogic, we had given 10 max connections in weblogic.properties,it is working fine. But i dont understand why it is not working in 9i AS though the max-connections is 50.
Kindly let me know the solution at the earliest as it is very urgent to get the program running...
Thanx and Regards,
Achyuth

Hi,
hopefully I can help you.
1. There are few helper classes which has to be ...We have just the same constellation. We have put the HelperClasses in the
J2EE/home/lib dir, NOT specifying it in the application.xml. So everything works fine.
The only thing: never, again: never put these files within WEB-INF and the lib-dir.
With the HelperClasses in both we have only faced massive problems, mostly ClasCastExceptions.
We had once all the helperClasses within J2EE/home/applications/lib, but this requires to
specify this dir within the orion-application.xml within the appl dir in applications-deployment.
It also worked fine.
2. How can i utilise connection pooling in oc4j. In data-sources.xml, i am using ...I'm not sure of this, but I think, the container handles Connection Pooling, no matter what Factory you
specify. But I think, the Class hasn't to be OracleConnectionPool ... but I have to check this (right now
I have no access to our datasource.xml ..)

Please help: Connection Pooling...

Hi everybody,
I am seeking help from our experienced fellows and senior programmers/developers.
I am working with Struts framework, TomCat and JavaBeans and developing a website.
I wanna make my own Connection Pooling class to handel all the connections.
Actualy, I don't wanna make Connection to the DB through my each Action Classes,
which are accessing the Database.
Would you please advise me that how it is possible and how I will refere to
my Connection Pooling Class within Struts framework. And if possible just give the
hints about the structure of the Connection Pooling Class.
Your kind help will be highly appreciated...

Hi..
Is it a requirement that u must use u'r own connection pool??
Coz each application server provides its connection pool.why dont u exploit one of those.. as u r using tomcat, definitely it wud also be providing a pool of its own.
