Oracle Pooled Connection

I'm using the oracle implementation of the connection pool.
But I don't know how to recognize when the phisical connections are down.
I can't use the method isClose() of the interface java.sql.Connection because it refers to a single connection.
this is the exception thrown when I try to execute it without the connection to the DB.
I can't resart every morning the application server....
java.sql.SQLException: Closed Connection
at java.sql.SQLException.<init>(SQLException.java:45)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:169)

at oracle.jdbc.pool.OracleConnectionCacheImpl.getConnectionOracleConnectionCacheImpl.java:251)
at oracle.jdbc.pool.OracleConnectionCacheImpl.getConnectionOracleConnectionCacheImpl.java:163)
Is there any solution?

Hi,
I m also trying to achieve connection pooling using oracle implementation but not yet successful,
could please paste ur related source code here?
Thnx n Regards,

Pooled Connection not supported in oracle forms 11g

Dear all,
I am using oracle from builder (11.1.1.4) and oracle database 11g Release 2. I can connect to the database from oracle forms 11g, when I use a dedicated or shared server connection mentioned in the tnsnames.ora file . But I want to use the oracle database 11g's new feature DRCP (Database Resident Connection Polling).
To do this a made a another POOLED connection (SERVER=POOLED) in the tnsnames.ora.I can connect to the 11g r2 database server from sqlplus using POOLED connection. But when I try it from form builder (11.1.1.1.4) it gives error with some unknown characters.
Then I tried it in linux frmcmp the message i got in terminal is can not *"Cannot obtain ORACLE version number"*
I have googled and also checked in metalink. But I got nothing.Thanks in advance for your help.

I don't think this feature is feasible for forms.
Quoting the documentation from
http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/manproc002.htm
Database Resident Connection Pooling (DRCP) provides a connection pool in the database server for typical Web application usage scenarios where the application acquires a database connection, works on it for a relatively short duration, and then releases it.
Forms keeps a permanent connection to the database, so a connection pool isn't gonna help you in any way.
cheers

WLS 10.3.0.0 Solaris SPARC and DBMS Oracle 10gR2 connection pooling issue

Hi all,
we are currently testing Weblogic Server 10.3.0.0 in order to migrate our production system from WLS 8.1 to it.
While testing the new setup, we encountered some strange behaviour of the connection pooling within WLS.
We configured a XA-Connection pool to our DB (Oracle 10gR2) by using
a) the Oracle XA-thin-driver delivered within WLS 10.3.0.0
and alternatively
b) the Oracle 11.2.0.2 OCI-driver of the Oracle 11g database client.
We´ve got the same issue with both variants. We defined an initial capacity of 5 connections and a maximum capacity of 30 connections.
Our application is running flawlessly using the connection pool, but the amount of active sessions between the application server and the database server is increasing rapidly and the maximum capacity is exceeded. We are seeing up to multiple hundreds of sessions from the application server to our database server. Obviously the connections aren´t cleaned up.
We are using the following settings for the JDBC-Connection:
initial capacity = 5
max. capacity = 30
Capacity increment = 1
Statement cache type = LRU
Statement cache size = 10
Test connections on reserve = true
Test frequency = 120
Test table name = "sql select 1 from dual"
seconds to trust an idle pool connection = 10
shrink frequency = 0
connecttion creation retry frequency = 120
login delay = 0
incative connection timeout = 10
max. waiting for connection = 2147483647
connection reserve timeout= = -1
Ignare in-use connections = true
pinned-to-thread = false
remoce infected connections enabled = true
Does anyone have an idea how to track/solve this issue?
Kind regards
Marc

Hi Joe,
we´ve tested with the thin driver using an initial capacity of 5 and a maximum capacity of 15. During our tests (in a very short time period) the maximum capacity has not been exceeded. But we saw some exceptions in the managed server logfile which made us curious.
When these exceptions are occuring, a new connection to the database server is established. We are seeing for a short time a total count of 6 connections which is immediately decreasing to the initial capacity of 5. We will do some further testing over the next hours and monitor the connection usage.
The connection we are dealing with is the one called "ZDB2".
This is an excerpt of the logfile:

How to config the oracle database connection pool in IAS

Hi,
Does anyone who hows to config the oracle database connection pool in IAS?
Thanks so much!!!
[email protected]
Jacky

Jacky,
You need do the following for oracle type4 driver:
1) register the driver:
$IAS_HOME/bin/jdbcsetup
Driver Identifier: Oracle_Type4_816 (whatever name you like)
Driver Classname: oracle.jdbc.driver.OracleDriver
Driver Classpath: .../classes12.zip (install this this zip file somewhere
and add this zip into the Classpath later).
2) DataSource Setup:
start iAS Administration Tool (iASAT)
Choose Database, unfold iAS1 (your app server instance),
choose External JDBC Datasource -> add: DataSource Registration
JNDI Name: yourPoolName
Driver Type: Oracle_Type4_816 (select what you just register)
DataSource Url: jdbc:oracle:thin:@hostName:portName:dbName
Username: your_user_name
Password: your_passwd
(Datasource Pool: using defaults for now): you can also customrize the
parameters for the pool.
3. Add classes12.zip into CLASSPATH.
In your application, you can use JNDI lookup to get the DataSource from
which you get the connection from the pool.
Hope this helps.
Good luck.

Closing pooled connections?? one at a time?

I've got an interesting need;
I've writen a custom UserManager for form based authentication.
class ValidateLoginManager extends AbstractUserManager
Authentication is to a legacy DB (Oracle) where all users have
been added as
Oracle users. So I've created a separate JNDI data source in
data-sources.xml
for pooling connections that I'll only use for authentication
(just a gut decission).
The container calls:
boolean checkPasswd (username, passwd) {
boolean authenticated = false;
try {
dbConnection = this.datasource.getConnection(username,
passwd);
authenticated = true;
} finally {
if (dbConnection != null)
dbConnection.close();
return authenticated;
This works great, since Oracle authenticates the connection
against it's user DB.
But the conn.close() does not close the session on the DB and
soon all MTS tasks are used up in idle sessions.
Any thoughts on forcing the connection to drop open sessions?
thanks, curt

Hi Curt,
For my custom usermanager I use a datasource specified in my data-sources.xml like this:
<data-source
     class="com.evermind.sql.DriverManagerDataSource"
     name="xyz"
     location="jdbc/OracleSecurityDS"
     xa-location="jdbc/xa/OracleXADS"
     ejb-location="jdbc/OracleDS"
     connection-driver="oracle.jdbc.driver.OracleDriver"
     url="jdbc:oracle:thin:@127.0.0.0:1521:xyz"
     inactivity-timeout="30"
/>
When you lookup the datasource using JNDI, make sure you use the name bound to the location specified in the "location" attribute and not the "ejb-location" attribute (as you usually do in your Ejbs).
I hope this helps.

Weblogic 6.1sp3 Oracle 9i connectivity issue

All,
I need your help in overcoming a Connection Pool issue. Details are:
-Configuration - Weblogic 6.1 sp2, Oracle 9i (on a P4 machine)
-Connection pool entry (config.xml)
<JDBCConnectionPool CapacityIncrement="1" DriverName="oracle.jdbc.driver.OracleDriver"
InitialCapacity="5"
MaxCapacity="25" Name="ejbPool" Properties="user=testuser;password=testpassword;dll=ocijdbc8;protocol=thin"
RefreshMinutes="10" ShrinkPeriodMinutes="5" Targets="myserver"
TestConnectionsOnReserve="true" TestTableName="dual" URL="jdbc:oracle:thin:@delmtest:1521:SID"/>
While starting weblogic, I get the following exception:
<Oct 25, 2002 5:00:46 PM IST> <Error> <JDBC> <Cannot startup connection pool "ejbPool"
weblogic.common.ResourceException:
Could not create pool connection. The DBMS driver exception was:
java.lang.ArrayIndexOutOfBoundsException
at oracle.security.o3logon.C0.r(C0)

at oracle.security.o3logon.C1.c(C1)
at oracle.security.o3logon.O3LoginClientHelper.getEPasswd(O3LoginClientHelper)
Any pointers will be greatly appreciated.
Thanks,
Raja

Problem solved!! Solution was to include the correct classes12.jar file in the
CLASSPATH BEFORE weblogic.jar. This is because weblogic.jar also ships with an
oracle driver, which is 8.1.7 (not 9i).
Thanks for your help..

Full stack trace is:Yep. The pool never got created. The failure below is during pool creation,
and is definitely an Oracle internal problem. You should simplify the
problem
by trying (maybe with Oracle's help) to make a simple JDBC connection
to your DBMS, with their driver, in a simple standalone program.

Data source for application using both pooled and non pooled connections

Hi guys.
I am integrating Oracle's connection pooling into an existing application that had formerly used dbConnectionBroker. It looks like this task should be quite straightforward. However, for consistency, I would also like to replace other Connection logic within the application to use Oracle classes. This will involve using OracleDataSource to obtain a Connection object. ( without pooling ).
So in this case, the application will use both pooled and non pooled Oracle connections. They will be connecting to the same database. The question I have is in regard to the use of data-sources.xml.
Are there any special considerations for the required attribute values within data-sources.xml under this scenario ?
Help will be greatly appreciated.
Regards.
Steve.

Hi Steve -
It should be feasible for you to define a single datasource using multiple location entries to indicate what sort of pooling behaviour you wish to use.
If you lookup and use the "location" attribute, you will receive a javax.sql.DataSource object which will not provide connection pooling.
If you lookup and use the "ejb-location" attribute you will receive a DataSource object that will support connection pooling operations.
Note that this is using the emulated datasource approach, and transaction support is limited to a single resource (one database) for these datasources - you won't get 2PC support for transactions.
If you need a transaction to span two separate resources (ie two databases in same tx) then you will need to use the non-emulated datasource approach.
There is a chapter in the J2EE Services Guide which describes the datasource model we have with OC4J. This might provide you with some more useful information. See Chapter 11 - http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97690/ds3.htm#1004903

I am also using OCI driver, as some of the functions for XMLType are not supported by thin driver.
I am getting similar error, as mentioned in the thread as

I have already tested with a standalone program and it works, but error is thrown with weblogic server.
My connection string is jdbc:oracle:oci:@//localhost:1521/orcl11
Any ideas on how this error can be avoided?

Error when creating Pool Connection

"Hi,
I have reviewed a lot of postings for this type of error and nothing mentioned in replies have helped me to get over this issue.
I am trying to create a pool via the admin console in WL6.0sp1. Using Oracle Thin driver. The config information is as follows:

actually, no, the thin driver reacts badly to being told a server. It tries to
become the type-2 driver and use the Oracle OCI stuff. If the customer can
make a standalone program connect to the DBMS with that driver and URL,
then maybe they need to alter the classpath of the server to have that
driver come before any weblogic stuff. We ship an older version of the
driver, and that may be being used because it's ahead in the classpath.

Oracle 10 Connection Cache (another question)

Hi all,
We have a large web app which currently uses JRun connection pooling. This is causing some problems so we'd like to try the Oracle Connection Cache mechanism. The thing is, each time a client gets a database connection, it runs a connection factory which looks up the datasource with jndi then creates the connection. So, in order for the Oracle 10 Connection Cache to work, do I need to change the logic so the datasource is static & we just do the look up once & set the cache-related properties at that point so every connection uses the same datasource object? This seems to me the way to go.
Thanks very much,
Jim Greetham

Perfectly Yes. If we try using Oracle's own Cahceing mechanism, it is out of our control. But if we custom deploy our own cacheing mechanism according to our need like you said, we need to develop our own codes using ojdbc6 driver available from Oracle.

NPE when using pooled connection

Hello. I have a client application connecting to an OC4J server running on a different machine. The OC4J server maintains a pool of connections to the Oracle database. My client is able to get the datasource from the server via jndi, and gets a non-null connection from the datasource. However, when I try to create a statement using the connection, I get a Null Pointer Exception. If I get a non-pooled connection from the datasource, everything works fine.
Here is the client code:
javax.naming.Context ic = getInitialContext();
javax.sql.DataSource dataSource = (javax.sql.DataSource)ic.lookup("jdbc/nanookDS"); //this gives you pooling
// javax.sql.DataSource dataSource = (javax.sql.DataSource)ic.lookup("jdbc/nanookCoreDS"); //this does not
for (int x=0; x<100; x++)
Connection conn = dataSource.getConnection();
if (conn == null)
System.out.println("null");
Statement stmt = conn.createStatement(); //fails here
ResultSet rs = stmt.executeQuery("select * from pmi.patient where patient# = 0");
rs.close();
stmt.close();
conn.close();
Can someone please tell me what's happening? I'm pulling my hair out...
BTW, the code above works fine when executed in a JSP on the OC4J server.
Thank you,
Brian Brown

How to pool connections to OID?

I am using oracle.ldap.util.jndi.ConnectionUtil to create context objects and could not find any information on how to pool connections using the oracle's API.
Any help will be highly appreciated.
-Ram

For info, I raised an SR on this and it seems the bug was fixed in OVD v11.1.1.4.
