HELP:Problem in creating a temporary CLOB using JDBC connection pooling
Hi All,
i am inserting a large xml document in an xml type column by creating a temporary clob of this document
tempClob = CLOB.createTemporary(conn, true, CLOB.DURATION_SESSION);
I am not having any success getting the following statement working using a JDBC connection pool rather than a hard coded URL connection
it works with:
"jdbc:oracle:thin:@server:port:dbname" connection
Does NOT work with:
datasource.getConnection()
Does any one know how to successfully get this to work?
urgently plz........
Hi Dharmi
Here is a quote of Dafna's post in [another thread in this forum|Re: Copy VC controls]
CE7.1.1 will be released at September 2008 for ramp-up customers.
There are many improvements and new capabilities in the new release of Visual Composer for CE7.1.1. Among the new features you can find:
The missing features from Visual Composer 7.0 (Html view, portal Eventing support (EPCM), JDBC, Undo/Redo, and more..)
Many layout & modeling improvements
Additional ALV table functionality - export to Excel, switch to chart, configure ALV behavior at design time
Integration of Visual Composer in Eclipse - additional entry point to the Visual Composer models from the NWDS. This integration provides the option to add a WD component (in case of missing functionality in Visual Composer), as a black box component to the Visual Composer model. Right-clicking the component will open the Web Dynpro perspective for creating/modifying the component.

How to use JDBC Connection Pools in a standalone application?
Hi, there,
I have a question about how to use JDBC Connection Pools in an application. I know well about connection pool itself, but I am not quite sure how to keep the pool management object alive all the time to avoid being destroyed by garbage collection.
for example, at the website: http://www.developer.com/java/other/article.php/626291, there is a simple connection pool implementation. there are three classes:JDBCConnection, the application's gateway to the database; JDBCConnectionImpl, the real class/object to provide connection; and JDBCPool, the management class to manage connection pool composed by JDBCConnectionImpl. JDBCPool is designed by Singleton pattern to make sure only one instance. supposing there is only one client to use connection for many times, I guess it's ok because this client first needs instantiate JDBCPool and JDBCConnectionImpl and then will hold the reference to JDBCPool all the time. but how about many clients want to use this JDBCPool? supposing client1 finishes using JDBCPool and quits, then JDBCPool will be destroyed by garbage collection since there is no reference to it, also all the connections of JDBCConnectionImpl in this pool will be destroyed too. that means the next client needs recreate pool and connections! so my question is that if there is a way to keep pool management instance alive all the time to provide connection to any client at any time. I guess maybe I can set the pool management class as daemon thread to solve this problem, but I am not quite sure. besides, there is some other problems about daemon thread, for example, how to make sure there is only one daemon instance? how to quit it gracefully? because once the whole application quits, the daemon thread also quits by force. in that case, all the connections in the pool won't get chance to close.
I know there is another solution by JNDI if we develop servlet application. Tomcat provides an easy way to setup JNDI database pooling source that is available to JSP and Servlet. but how about a standalone application? I mean there is no JNDI service provider. it seems a good solution to combine Commons DBCP with JNID or Apache's Naming (http://jakarta.apache.org/commons/dbcp/index.html). but still, I don't know how to keep pool management instance alive all the time. once we create a JNDI enviroment or naming, if it will save in the memory automatically all the time? or we must implement it as a daemon thread?
any hint will be great apprieciated!
SamTo my knoledge the pool management instance stays alive as long as the pool is alive. What you have to figure out is how to keep a reference to it if you need to later access it.

Problem to call a procedure while using External connection pooling in TopL
HI all,
I have implemented external connection pooling in TopLink with JBoss 4.0.3SP1 and it is working fine. But after the connection pooling I am getting error while executing stored procedure with TopLink on Sybase. This is the error I am getting......
Stored procedure 'P_InsReleaseToManufact' may be run only in unchained transaction mode. The 'SET CHAINED OFF' command will cause the current session to use unchained transaction mode.
I got one solution to this problem as to set a tag in sybase-ds.xml file(which is used in JBoss to enable connection pooling) ..............
<connection-property name="SQLINITSTRING">set chained off</connection-property>
but still it is not working.
Can some one please tell me about the solution.Try
session.getLogin().handleTransactionsManuallyForSybaseJConnect(); -
ResultSet problem with a jdbc connection pool implementation
Hi
I'm trying to use jdbc connection pool in my java application (js2e 1.4.0_01)
from the example at http://www.developer.com/tech/article.php/626141
In my main() code, in addition to JDBCConnection, JDBCConnectionImpl and JDBCPool classes, i use
JDBCConnection conn;
conn = new JDBCConnection(dbName);
// make a statement
sqlString = "SELECT........."
ResultSet rs = null;
rs = conn.sendRequest(sqlString, rs);
// print result
while (rs.next()) {
Unfortunately i get an error like "ResultSet is closed" in the line corresponding to rs.next. The error disappears if i remove the line
stmt.close();
in the method sendRequest of the JDBCConnectionImpl class.
1) Does anybody knows the solution?
2) How to close all connections?
Thanks you in advance.Hi ,
You are closing the statement and then trying to use resultset , which is not going to work .So close then statment after using resultset .Ideally the code should be like this
try {
conn = // get the connection
pstmt = conn.prepareStatement(sql);
rs = pstmt.executeQuery();
while ( rs.next()){
// do something
catch (Exception ex) {
finally {
try {
if (rs != null)
rs.close();
if (pstmt != null)
pstmt.close();
if(conn!=null )
conn.close(); -

BLOB / CLOB operations using JDBC connections taken from WebLogic 6.0 connectrion pool
Hi..
I need to do some CLOB operations using JDBC connection taken
from WebLogic 6.0 connection pool. Will weblogic 6.0 supports it.?
I am getting errors when trying to do it in normal way .
It seems like ResultSet.getClob() returns an RMI (kind of ) object
instead of the Clob object.
If you have any idea . Pls respond to [email protected]

Problem in retriving varray when using weblogic connection pool
Hi,
I had similar problem when we I am using the weblogic connection pool. I had similar setup i.e weblogic 5.1 servicepack9 and oracle 8.1.7.
I cofigarud the weblogic connection pool using Oracle thin driver.
But if I am using with oracle thin driver directly I am able to retrive.
If any one know how to retrive varray from procedure using weblogic connection pool please send me it.
Thanx.

JDBC connection pool failures when used by JMS stores
We are using WebLogic 6.1 sp2. We defined a separate connection pool for use by
a JMS Store.
<JDBCConnectionPool Name="sybaseJMSPool"
Targets="cluster00"
InitialCapacity="2"
MaxCapacity="10"
DriverName="com.sybase.jdbc2.jdbc.SybDriver"
Properties="[email protected]@;[email protected]@;charset=utf8"
URL="jdbc:sybase:Tds:@jms.db.host@/@jms.db.name@"/>
(note that the @xxx@ string are replaced by actual values).
We are using Sybase Jconnect 5.5 to a Sybase ASE 12.5 database.
We deployed this configuration on a number of environments (testing, staging,
..). The actual hardware and network configuration is different for the different
system, but the WebLogic domain stays the same regarding this issue.
On the test system we frequently get the following exceptions:

This problem did not occur on another system which was used during a 2 day stress
testing session.
It seems that the problem occurs after a period in which no user request where
made. The user requests trigger EJB's that start sending JMS messages.
When the problem occurs, the JMS messaging systems seems to lock up as no messages
are received anymore by the different listeners (MDBs).
Undeploying and redeploying the JBDC connection pool solves the problem. This
solution is unacceptable in case of a production system.
A similarly defined connection pool, which is used by the EJBs to make database
connection, does not manifest this problem.
<JDBCConnectionPool Name="sybasePool"
Targets="cluster00"
InitialCapacity="10"
CapacityIncrement="5"
MaxCapacity="50"
PreparedStatementCacheSize="150"
DriverName="com.sybase.jdbc2.jdbc.SybDriver"
Properties="[email protected]@;[email protected]@;JCONNECT_VERSION=6;charset=utf8"
URL="jdbc:sybase:Tds:@db.host@/@db.name@"/>
The JDBC connection pool is used as follows by the JDBC store
<JMSJDBCStore ConnectionPool="sybaseJMSPool" Name="JDBCStore00" PrefixName="JMS00"/>
<JMSServer Name="JMSServer00" Store="JDBCStore00" Targets="node00">
<JMSTopic JNDIName="ADIS.JMSError" JNDINameReplicated="false" Name="ErrorTopic"/>
<JMSTopic JNDIName="ADIS.Status"

<JMSTopic JNDIName="ADIS.OrderChange" JNDINameReplicated="false"

</JMSServer>
Turning on the "Test Reserved Connection" with a appropriate test table does not
help.
Some sources on the internet tell us that JZ0C0 errors in the Jconnect driver
can be related to network problems. Nevertheless the connection pool should be
able to cope with this.
Can you provide any solution for this ? Or give us hints what can cause the problem
Zhenhao Qi wrote:
thanks! Joe.
The SQL statement itself can no longer be simplified, the long excuation time is due to the database size and complicated Select criteria. I can easily reproduce the problem by using this SQL. I tried "BEA's Oracle driver (Type 4): Version 8.1.7,9.0.1,9.2.0". the question can be dissect into 2 pieces:
1) why the jdbc connection (using oracle.jdbc.OracleDriver) won't return anything if the SQL execution time > 5min, that is probably the Oracle's problem
2) why the occupied connection pool won't release even I set "Statementtimeout=600", this is Weblogic's problem.
ZhenhaoHi. Yes, (1) is oracle's problem. (2) may also be. The JDBC spec has very few
allowances for one thread to interrupt a second thread's JDBC call. If we
transmit your timeout request by calling setQueryTimeout() on the oracle
statement, and if you have a weblogic-controlled transaction we call
Statement.cancel() on any ongoing statement, we end up relying on whether
the Oracle driver implements and responds to those calls.
Are you doing weblogic-controlled transactions? Are you/can you
call Statement.setQueryTimeout() on your statements, or are these
generated JDBC queries?
If you can duplicate the problem using the weblogic.jdbc.oracle.OracleDriver
we have some other debug avenues. This would be good even if you really
want to use the thin driver, because we will do the same JDBC calls to
either driver, and the debug would prove (if) we set up a query timeout
and if we call cancel(). If we do, then we can know that it is the Oracle
driver failing in these regards.

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. -

Simplified JDBC Resource Configuration
In WebLogic Server 9.0, the number of JDBC resource types was reduced to simplify JDBC configuration and to reduce the likelihood
of configuration errors. Instead of configuring a JDBC connection pool and then configuring a data source or tx data source to
point to the connection pool and bind to the JNDI tree, you configure a data source that encompasses a connection pool.
Note: Because of the new configuration design, you can no longer have multiple data sources that point to a single connection
pool. Instead, you can create additional data sources, each with its own pool of connections, or you can bind a single data source
to the JNDI tree with multiple names. See Binding a Data Source to the JNDI Tree with Multiple Names for more information.

JDBC Connection Pool to DB2 database - Problem

Any idea as when we get this exception? -
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 do I find out what is using a connection pool
This morning weblogic 8.1.5 complained it couldn't expand a connection pool because it had reached is max concurrent connects limit.
The issue I have is that I don't actually know what is using the connection pool. It should be defunct and redundent but obviously not.
This caused all the threads to be consumed and the managed server hung.
Does anyone know wether it's possible to interigate the pool to find out what it's doing ? I can't check the db as it's managed by another company and I have a v limited read only account.... I can't even select from v&session.
Cheers in advance for any help.Dave Snaith wrote:

and whatever applications are still trying to use it will get
quick exceptions.

java.rmi.RemoteException: com.sap.engine.services.dbpool.exceptions.BaseRemoteException: Error during start of application "sap.com/JDBCConnector_KedDS.xml". [id = StartupError]
