Creation of connection pools and data sources
Hi,
is there a possibility to create jdbc connection pools and data sources not manually, with a script or a mbean?
That would be helpfull, because at the moment every developper has to do that for himself (because of the individuals generated passwords).
Thanxs
The weblogic.management.configuration.JDBCDataSourceMBean
defines a non-transactional JDBC data source.
http://e-docs.bea.com/wls/docs90/javadocs_mhome/weblogic/management/configuration/JDBCDataSourceMBean.html
The JDBCConnectionPoolMBean defines a JDBC connection pool.

Some doubts in using resource-ref,connection pool n Data-source
Hi all ,
I need little bit clarification in the following points.
1) Does the connection pool which is created can be displayed in JNDI Tree???
I am seeing only DataSOurce in the JNDI Tree Only.
2)In case of Bean Managed Persistance, in ejb-jar.xml,
I had given the following info.
<resource-ref>
<res-ref-name>ramukkDataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>Does the <res-ref-name> refers to Datasource Name??
In weblogic-ejb-jar.xml
<reference-descriptor>
<resource-description>
<res-ref-name>ramukkDataSource</res-ref-name>
<jndi-name>ramukkpool</jndi-name>
</resource-description>
</reference-descriptor>Here <jndi-name> refers to connection pool as per weblogic bible book.
If so when i deployed my ejb into the server iam getting Datasource cant be found.
If i had given like the following,
In ejb-jar.xml
<resource-ref>
<res-ref-name>jdbc/ramuJndi</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref> In weblogic-ejb-jar.xml
<reference-descriptor>
<resource-description>
<res-ref-name>jdbc/ramuJndi</res-ref-name>
<jndi-name>jdbc/ramuJndi</jndi-name>
</resource-description>
</reference-descriptor>Then only my ejb code is successfully deploying doing some work which is as per xpectation.
Can any body tell why I have to give the same name for <res-ref-name> n <jndi-name>??
I am working on this problem from last one week. Still not found the solution.
Connection Pool Creation
GENERAL::
Name : ramukkpool
url : jdbc:mysql://localhost:3306/test
Driver Classname: com.mysql.jdbc.Driver
Properties :
user = root
Password = XXX
create
TARGETS::
i had shifted myServer from left side to right side n clicked >>Apply
(Techncially can we say this as deploying the connection pool into server ???????????
If not how to deploy the connection pool into server??)
I did not get any errors in the console.
Now i am creating a datasource
CONFIGURATION:
Name : ramukkDataSource
JNDIName: jdbc/ramuJndi(Does we have to follow this convention only?? i.e JNDIName should start with jdbc/ only)
PoolName: ramukkpool
create
TARGETS::
I had shifed myServer from left to right n >>Apply.
Now also i did not get any errors in the console.Thanx(in advance),
ramuI have read the documentation.
I changed my class to oracle.jdbc.pool.OracleConnectionCacheImpl from
oracle.jdbc.pool.OracleConnectionPoolDataSource
I observed in the EM that the Open JDBC Connections and Total JDBC Connections are the same. When I used oracle.jdbc.pool.OracleConnectionPoolDataSource my Total JDBC Connections was increasing and Open JDBC Connections remains 0.
My question still remains unanswered, could some kindly help.
Q? I have defined a data source in JDeveloper using
oracle.jdbc.pool.OracleConnectionCacheImpl
In my java bean I am using the code pasted below to make a connection to database.
Can some one tell whether I am using the correct method of connection pooling mechanism or do I need to make some changes? This application uses JSP and used by lots of people which hits database very frequently.
Any help is highly appreciable.
Thanks in advance.

How dynamically create connection pool and Datasource
Hi
How I can dynamically create a connection pool and Data source in Oracle 10g Application server. In our J2EE application the user will be login with db user name, password and database name. I want to create connection pool and data source on the fly while login the user with database name. I our application we have access approximate 80 Databases. so my approach is given bellow
1) Planning to create 80 connection pools and 80 Data sources so when user logs in while selecting the db name i will call the appropriate data source and create the DB connection. Is there any limitation to create number of data sources in oracle app server?
2) Create DB connection with out using connection pool and data source. But i am not prefer this approach coz we need to handle some transaction in our application.
Kindly throw some light on managing connection pool programmatically or in application run time.
I would really appreciate if any one can provide any links or any inormation on this issue.
Thanks in advance.Kindly let me know is there any drawbacks to create 80 Data Sources to connect 80 database in Oracle 10G App server and each data sources should have one connection pool. so i need to create 80 connection pool. Please let me know is this right approach or any work around to create Data source on fly for each request for corresponding database.

OC4J 1.0.2.2.1, connection pooling, and over-riding the default username and password
We are using OC4J 1.0.2.2.1 and connection pooling with data-sources.xml
In data-sources.xml, we have specified the default username and password.
However, there are situations where we will want to use a different username and password and still use the connection pool. For example:
public static Connection getConnection(String aUserNameS, String aPasswordS) {
Connection conn;
try {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("jdbc/ejb/OracleDS");
conn = ds.getConnection(aUserNameS, aPasswordS);
} catch (Exception ex) {...}
return conn;
Will this work? I mean, is it possible to specify a different username and password in the JNDI lookup and have it over-ride a provided default username and password in data-sources.xml?
Thanks,
EdThis may be problem with your userid/password. Please look the $OC4J_HOME/j2ee/home/config/principals.xml whether you have a right userid password.
I did a quick test at looking up at "jdbc/OracleDS" for two users admin and SCOTT and this works fine both in 1.0.2.2.x an 9.0.2
I got your errors when I had wrong passwords for these users

Weblogic - jndi and data source connectivity problem
Unable to deploy EJB: OrganizationEJB from sempire_bc.jar
The DataSource with the JNDI name: OrganizationDB can not be located. Please ensure
that the DataSource has been deployed
successfully and that the JNDI name in your EJB Deployment descriptor is correct.
In my console, I have created a connection pool 'oraclePool' and 3 datasource
'jdbc.GangsterDB', 'jdbc.OrganizationDB' and
'jdbc.JobDB'. I have also specified the target server and there seems to be no
error. I have checked 'Monitor All Connection
Pools' and oraclePool is running. I still do not understand the problem that I
am getting and have no clue how to solve it.
Thank you

</weblogic-rdbms-jar>just looking at you weblogic-ejb-jar.xml,
your ejb jndi names are the same as the data source jndi names...this
may be your problem.

Creation of a generic extractor and data source for the FAGLFLEXA table
Hi All,
Need to create a generic extractor and data source for the FAGLFLEXA table to support AR reporting. This table contains the necessary profit center information to perform LOB reporting against the AR data.
Please advice on how to do this.
Regards, VishalHi Vishal,
Its seems a simple a work out.
1.Go to RSO2 & choose the relevant option ie. whether you want to create Transactional DS, Master Data DS or Text DS.
2. Name it accordingly & then create.
3. Give description to it & then give table name FAGLFLEXA.
4. Save it & activate. If you need it to be delta enabled then click over Delta & you can choose accordingly.
If you still face some problem then do mail me at [email protected]
Assign points if helpful

Connection pool and Connection factory difference?
Hi,
Can someone clarify the difference between connection pool and connection factory.
I know connection pool is some thing like a pool of database connection manitained at one place so that an application or client can use it when it requires.
Then wat exactly is connection factory..say in 10g we always put a connection factory name in all adapters and acces the data sources like DB ,FTP,AQ ..etc
can someone clarify??
regards,To conserve system resources and to improve the performance of transactional applications, WebLogic allows you to define a pool of client connections (generally database but may be a FTP,FILE etc. as well)
A Connection Factory object encapsulates a set of connection configuration parameters that has been defined by an administrator. A client uses it to create a connection with a service provider (generally JMS).

</weblogic-rdbms-jar>The problem I see is wrong url for jDriver.
you have to say: jdbc:weblogic:oracle
In properties what you need is:
user=
password=
server=
Actually, your connetion pool is not created yet. It has problems. Make sure you create connectionpool successfully
first.
Thanks,

As one can expect from early adopter release there could be some bugs but I can't find any references in forum to my situation:
* My 11g XE database and listener are starting as windows services when server boots operating system (Windows Server 2003 R2).
* I configured my web server (unsupported Jetty 9.0.0.M1) to start as windows service when operating system starts.
* Apex Listener 2.0.0.268.17.05 configured to connect with XE using JDBC thin driver with default settings (initial pool size 3, max statements 10, min connections 1, max connections 10, inactivity timeout 1800, abandoned connection timeout 900)
* Because web server starts a bit faster than Oracle database when apex connects first time it gets "ORA-12528, TNS:listener: all appropriate instances are blocking new connections" (could be that database still starting but already registered service with listener)
* From listener.log file I can see that all further connections made from Apex listener succeeds
* When I try to open any apex page with browser I am getting 404 error and apex listener logs error (*time is 2 days after system startup*):
2012-11-30 3:56:02 PM oracle.dbtools.common.config.db.DatabaseConfig badConfiguration
SEVERE: The pool named: apex is not correctly configured, error: Listener refused the connection with the following error:

* For some reason apex listener keeps first connection status and won't try to establish new connection if first attempt finished with ORA-12528
* The same scenario is valid when at time of web server start oracle database/listener is not available - even if database and listener starts and apex successfully establishes further connections all apex pages gets 404 error
* If I restart web server windows service (while oracle db and listener still running) browser opens apex pages without errors and apex listener does not log any errors
* I know that I can avoid this error delaying start of web server windows service but it would be nice to have production release 2.x without such bugsHi,
Is there any way to use the connection pool or Datasource while connecting to database?If I am using a stateless sesssion bean and using a Data Access layer which just creates a database session to write the persistence toplink objects how I can make use of application server connection pool?Hi Vinod,
Yes, TopLink allows you to use the app server's connection pooling and transaction services. Chapter 2 of the Oracle9iAS TopLink Foundation Library Guide provides details as do the TopLink examples. The easiest way to set this up is by using the sessions.xml file. The sample XML below is from the file <toplink903>\examples\ias\examples\ejb\sessionbean\sessions.xml. Here we are adding the datasource defined in OC4J and specifying that we are using the OC4J transaction controller also.
<login>
<user-name>sa</user-name>
<password></password>
<datasource>java:comp/env/jdbc/ejbJTSDataSource</datasource>
<uses-external-transaction-controller>true</uses-external-transaction-controller>
<uses-external-connection-pool>true</uses-external-connection-pool>
</login>
<external-transaction-controller-class>oracle.toplink.jts.oracle9i.Oracle9iJTSExternalTransactionController</external-transaction-controller-class>
When using this approach you need to change your TopLink code slightly in the EJB methods:
a. Acquire the ACTIVE unit of work from the server
session (again, see the EmployeeSessionEJB code
example) with something like:
UnitOfWork uow = clientSession.getActiveUnitOfWork();
b. Calls to uow.commit() can be ommitted or commented out
because the EJB will handle this. Note that of course
the methods you create in the EJB that are using this
approach must have TX Required (default).
Hope this helps.

What's the difference between using a connection pool and a datasource
Howdy. I figure this is a newbie question, but I can't seem to find an
answer.
In the docs at bea, the datasource docs say
"DataSource objects provide a way for JDBC clients to obtain a DBMS
connection. A DataSource is an interface between the client program and the
connection pool. Each data source requires a separate DataSource object,
which may be implemented as a DataSource class that supports either
connection pooling or distributed transactions."
In there it says the datasource uses the connection pool, but other than
that, what is the difference between a connection pool and a datasource?Thanks for the info. I think it makes some sense. But it's a bit greek.
I'm sure it'll make more sense the more I work with it. Thanks.

Peter,
Here is a more formal definition of a DataSource from the Sun site
"A factory for connections to the physical data source that thisDataSource object
represents. An alternative to the DriverManager facility, a DataSourceobject
is the preferred means of getting a connection. An object that implementsthe
DataSource interface will typically be registered with a naming servicebased
on the JavaTM Naming and Directory (JNDI) API.
The DataSource interface is implemented by a driver vendor. There arethree types
of implementations:
Basic implementation -- produces a standard Connection object
Connection pooling implementation -- produces a Connection object thatwill automatically
participate in connection pooling. This implementation works with amiddle-tier
connection pooling manager.
Distributed transaction implementation -- produces a Connection objectthat may
be used for distributed transactions and almost always participates inconnection
pooling. This implementation works with a middle-tier transaction managerand
almost always with a connection pooling manager.
Does that help clarify the distinction?

How to connect to different data sources in XI 3.1 UNIVERSE?
hi experts,
We are going to migrate from BO 6.5 to BO XI3.1.
and we have different data sources to extract and generate the reports using various tools like Webi,Crystal Reports, Deski etc.
1 How to connect to different data sources like SAP BI query, DB2, Oracle etc,, provide me the step by step solution.
2 We need to migrate the universes and reports from BO 6.5 to BO XI 3.1 using the Report Conversion Tool.
can we directly convert from the deski reports to Webi or do we need to migrate first through Import Wizard?
3 Scheduling the Reports through Infoview
4 Various issues and how to resolve those issues, we generally face while scheduling, and while creating the queries like for example time out errors etc..
5 BO Security
6 Universe creation with best practices and the loops,contexts,aliases etc..
please provide me the step by step solution documents and links.
thans in advance
venuscmI would recommend to take a look at the official documentation. YOu can find this here
http://help.sap.com
NAvugate to SAP BusinessObjects->All products and the select the product you want eg. BusinessObjects ENterprise or Universe designer and the appropriate version XI 3.1. Take a look at the admin and the user guides.
Currently the Data FEderator will allow you to buid a universe that access data from various data sources. Another option is to merge queries from different universes at report level.

WebLogic 6.1 losing connection pools and deployments on restart
Hi,
Has anyone else seen a problem where it appears that processing of
config.xml is incomplete, without any error message? For example, a
connection pool that is deployed fine through the console, shows as
undeployed (available) when the server is restarted, regardless of how the
server is shut down.
Most recently, this happened with a connection pool and tx data source I've
been using for weeks, when I added a RDBMSRealm going to the same database.
The EJB deployment that needs the tx data source fails on startup, but if I
redeploy the connection pool and tx data source through the console and then
deploy the EJBs everything works. Until I restart the server, when the
problem recurs.
If I go back to my backed up config.xml, without the RDBMSRealm, everything
works fine at startup.
I see no error message in any log file: it's as though config.xml entries
are being ignored.
I attach my config.xml file. The multiple targets are the result of
redeploying through the console: editing them out does't fix the problem.
Regards,
Rod Johnson

Not getting connected to a data source in obiee 11g
Hi friends,
In OBIEE 11g I cannot able to import meta data into a new repository...
It is not connecting to data source for importing meta data
It throws the error like connection is failed....
I have also restarted the services and also checked for the odbc connectivity it is showing connection is
successful..
I also entered the corresponding details in TNS notepad...
These are the following details
