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.

How to create connection objects in the NTDS settings container of a DC with LDIFDE

The following link shows some examples of how to automate creating subnets without having to use the sites and services console: http://codeidol.com/active-directory/active-directory/Site-Topology/Creating-a-Subnet/
My question is how can use LDIFDE to create connection objects? We don't use the defaultipsitelink and are creating the connections manaully. How can I use LDIFDE to create connection objects like this? I have not been able to find any examples on the internet.
Thanks for any replies.

KCC does the job of creating connection object automatically reading site/subnet/sitelink info, so why you need to create manually.

How to create connection to cluster of Oracle database server?

Hi, all!
I have to create connection to Oracle cluster. How to do that?
I can make a connection to one server but to cluster ....
I saw many documents but without any result.

Hello
Two servers with oracle database server installed organized as a cluster.
Both server work in parallel, when one of them stop work the other takes connection automaticaly.
The connection to the cluster is not usual as a one server.
I have to specify both servers.Any time i can make a connection to one of them but when he stop work my connection will be broken.
Because of that the servers work under oracle server software.
So i can make a connection to one of them and both.
This is made because it is for production firm with many test computers that work 24/7 and send information to this oracle server.
So i have to make a connection to the general oracle cluster (the two servers simultaneously).
I saw some connection strings to do tha written on Visual Basic but i have no idea how to do that in C/C++.
There is no information about that in the Oracle tutorials and manuals.
I need this explanation because i make a connection without TNS config file.
Can you help me?
I will be very appreciated.

I spent many hours when i first implemented connection pooling trying to put it together. The information is scattered and the config has changed slightly from 5.0 to 5.5 etc. This is how I got it working in 5.5.17:
* server.xml seems to be a wrong place for the pool configuration if you consider it to be an application specific thing. It might be a better idea to put it into C:\tomcat55\conf\Catalina\localhost\ConfigFileForYourWeapp.xml as follows:
<Context path="/ClientLink" docBase="C:\eclipseWorkspace\PortfolioUI3\WebRoot">
      <Resource name="jdbc/testportfolios" auth="Container"
                     type="javax.sql.DataSource"
                     factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
                     username="****" password="******"
                     driverClassName="com.mysql.jdbc.Driver"
                     url="jdbc:mysql://192.168.0.101:3306/testportfolios?user=***********&password=***********&useUnicode=true&characterSet=swedish"
                     maxWait="10000" maxActive="30" maxIdle="10" removeAbandoned="true"
                     removeAbandonedTimeout="60" logAbandoned="true" testWhileIdle="true"
                     minEvictableIdleTimeMillis="4000"
                     timeBetweenEvictionRunsMillis="60000" validationQuery="SELECT '1'" />
      </Context>* Then add the following snippet into web.xml in your webapp directory:
<resource-ref>
                <description>Database pool defined in ClientLink.xml</description>
                <res-ref-name>jdbc/testportfolios</res-ref-name>
                <res-type>javax.sql.DataSource</res-type>
                <res-auth>Container</res-auth>
           </resource-ref>* Next put the jdbc-driver jar in a place where tomcat can find it. That is common\lib. Note that the shared/lib does not work.
* Get connections in java as follows:
                try {
                     Context initCtx = new InitialContext();
                     DataSource ds = (DataSource) initCtx.lookup("java:comp/env/jdbc/testportfolios");
                     this.connection = ds.getConnection();
                } catch (NamingException e) {
                     throw new RuntimeException("Java naming exception when getting connection from tomcat pool: " + e.getMessage());
                }I hope that this helps you to save the time I lost figuring this out!

How to create a sql server database in SQL DEVELOPER.

I installed the SQL DEVELOPER 1.5.5, but i can't found where to create the sql server database in it. please kindly tell me if you feel free.
Thanks so much in advance.

Hi,
Take a look at the main [ SQL Developer page on OTN|http://www.oracle.com/technology/products/database/sql_developer/index.html]. There is a link you should find useful, it's the Getting Started link under the Migration section. This explains how to download and setup the drivers you need to correct to non-Oracle databases. There are also links to online demonstrations on how to create connections to these databases. See how you go with that material.
It should help.

How to create a dedicated-server session (to a oracle database)

Hello!
I've installed Oracle SQL Developer (Rel.: 2.1.1.64.45) and Oracle Instant Client (Rel.: 11.1.0.7), my Client is configured to enable connections using tnsnames.ora or host-/easy-naming (sqlnet.ora-entry: NAMES.DIRECTORY_PATH= (TNSNAMES, HOSTNAME)).
Regardless how I configure a database-connection in SQL Developer, I allways "only" get a shared-server connection (even when using a tnsnames.ora-entry with "...(SERVER = DEDICATED)...").
SQL Developer (any release) in combination with ("fat") client 9.2.0.7 (using tnsnames.ora) creates dedicated-server sessions as wanted.
Is there any setting in SQL Developer which dis- and/or enables dedicated-server sessions or is this a feature/problem of Instant Client 11.1.0.7?
Any ideas and/or suggestions?
(Additional Info: There is no difference in this behavior according to the connected database, I work with databases 9.2.0.7, 10.2.0.3, 10.2.0.4, 11.1.0.6 and 11.2.0.1)
With kind regards
Klaus

Creating Connection Pools/ Connection Pool does not exist error

Hi everyone -
I have a question about when/how weblogic creates connections pools.
Here is the scenario. Sometimes when our weblogic server starts, our
oracle database is not available. Therefor, weblogic can't create the
connection pool. However, after oracle comes weblogic up, weblogic
could create the connection pool, but it doesn't appear to be smart
enough to do this. Is there a way to ask weblogic to attempt to
recreate a connection pool?
We've noticed this behavior on weblogic 6.0 sp2.
Thanks,
Scott

If you define the pool with an initial size of zero, you should be OK. The
server is currently a little severe with a pool when the server cannot
create the pool with it's initial capacity, the pool isn't created. The server
could create it later, if told to via the console or via the admin command line,
or via the dynamic pool API, but init=0 is easiest.
