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.

Server-side connection pooling for clients in different VM's

We have a need to centeralize our connection pool manger.
Is there a server-side connection pooling manger product to allow multiple clients running in different VM's to connect to and share connection objects to the same Database?
e.g. An applet, and a swing and a servlet/web app application all running in different VM's will connect to this central connection pool manager and share connection objects to the same DB.
We are using connection pooling for all of our applications but each application is maintaining its own connection pool and it is becomming a nightmare to manage and configure each one.
Also, we have to have at a miniumum one connection open per application to access the database regardless of wether we are using connection pool or not. This means that 100 apps(running in different VM's) will use at minimum 100 connections... where all of these 100 apps will do just fine with just 10-15 connections.
while back we used T3 server but can't find this product on BEA web site any more.
does jdbc 2.2 or 3.0 have any server side pool management specs outlined?
Please HELP as we can't afford anymore licensing fees for our company.
oh.. We can't open and close connections on each query as they will be slow.
any suggestions greatly appreciated.

if i understand you question, i don't think this is possible, since the Connection interface (and basically all of the related jdbc interfaces) aren't Serializable.. so they can't be sent over the wire to your client(s).
However, you could feasibly write some server side connection pool, and some server side facade which will allow clients to submit queries (either SQL String's or however you want to do it - obviously a more elegant solution involves a series of classes which dynamically create sql based on query criteria), then the server can grab a connection, execute the query, cycle through the results and populate some result object of your creation and send that back over the wire to your client(s).

Different connection pool for a report

Hi experts,
For one my reports using 'CLOBS' like explained (http://oraclebizint.wordpress.com/2007/11/12/oracle-bi-ee-101332-working-with-clob-fields/) I need to disable parallel processing because it's not supported.
NO_PARALLEL and NO_INDEX_PARALLEL hints at the query level couldn't disable the parallelism.the optimizer still use it.
I thought about having a new connection pool that contains 'before query' and 'after query' statements that will disable the parallelism.This will take me a lot of time to rebuild the whole Presentation and Business layers to point to a new physical tables.
Any one has an idea about how I can use another connection pool for a specific report?
Regards

I have the problem. My issue is that I need to have a webservice use the 2 database connection pools I have created. Originally the pools were Non-XA. When I change them to XA I cannot get the JMS JDBC Store to work.
java.lang.Exception: WebLogic Pool Driver doesn't support XA driver, Please change your config to use a Non-XA driver
However, part of what you wrote below I don't understand. You said you configured a brand new JMS JDBC Store and was able to use an XA Connection Pool? I tried to delete my existing one and create it anew, but was not able to use an XA pool.
Is there any solution around this? I need to have an XA Pool for a webservice but non-XA for my JMS Store.
"After much digging I found documentation that you cannot configure an XA JDBC Connection Pool for use with a JMS JDBC Store: http://edocs.bea.com/wls/docs81/ConsoleHelp/jms_config.html#1128929
The only thing is that if I configure a brand new JMS JDBC Store and make it use the XA JDBC Connection Pool (instead of just selecting the new MySQLXAConnPool from the list that includes the non XA pool) it works without an error."

Set up DB Connection Pool for Oracle DataBase Using Java App Server8

Hi,
In the Admin Console of Java App Server 8, I tried to create a connection pool for the oracle database. I chose Resource Type to be "javax.sql.ConnectionPoolDataSource" and the Vendor is Oracle. So the Data Source Class Name is filled by the system to be "oracle.jdbc.pool.OracleConnectionPoolDataSource". Now, I set up the class path to point to the database driver class "sun.jdbc.odbc.JdbcOdbcDriver" and also the to the Data Source Class Name. Also I set up the JVM options in the console. Restart the server, and then try to ping to the database, but get the error:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: No suitable driver
I don't understand what else I should do and why this error is coming?
Please help me out.
Thank you
Regards,
Sarah

Hi,
I've already solve the problem. I did the following:
set the Url to be: jdbc:oracle:thin:@hostname:port:SID
set username
set password
add oracle.jdbc.drivers.OracleDriver into the JVM options -Djdbc.drivers
restart the server
test the connection
it works :)

Problem creating a connection pool for mssql server

Hi
i downloaded the microsoft type 4 driver for JDBC and i have installed it. now i am trying to create a connection pool for MS Sql server but each time i ping i keep getting an error telling me
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket
please can someone help out on this
Ifeanyichukwu

I assume that you installed the driver correctly. You did go into the app sever admin and set the JVM path? You do this by going to Application Server | JVM Settings | Path Settings and putting in an entry for Classpath Prefix.
If that is done and it's not something basic like your database isn't turned on, then it must be your settings. To to Sun's site and search for dbping. http://developers.sun.com/prodtech/appserver/utilities/dbping/dbping_overview.html
Deploy this program and run it. It is a very simple tool that lets you test different property settings. Play around with different settings until you get a ping.
If that doesn't work post your connect pool settings.
Good luck

Create a dedicated connection pool for initialization blocks

Hi,
I'm using OBIEE11.6, then I set a session initialization block in RPD, and this block is based on connection pool '"My_DB".
"My_CP"'.
when Consistency Checking it warning as follow:
Initialization Block 'Authorization' uses Connection Pool '"My_DB".
"My_CP"' which is used for report queries. This may impact query performance.
but there is no table under the connection pool "My_CP",so I don't know why it say it's used for report queries? and how to remove the warning?
any one know it?
Thank you!

Hi Leo,
Generally, when there is only one connection pool for a database in physical layer, the BI Server understands this to be the only connection pool for queries (I do not think this really checks if there are underlying tables. I think this is because there is a way to add tables to a database by right clicking on connection pool and choosing import metadata.).
As a good practise, when you have init block pointing to a specific database please make sure that you create another connection pool just for the use by init blocks. This would make sure that the report queries and init blocks do not go on a single pool.
So, for your case, create a second connection pool and point your init blocks to the second one. Yes, you cannot point to the first one as it is kind of reserved by BI Server for reports. (Unless you change this in the Options menu of .rpd)
Hope this helps.
Thank you,
Dhar

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..
