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"
Name="OrderChangeTopic" RedeliveryLimit="3"/>
</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

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.

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.

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.

Issue JDBC connection pool with Glassfish 3.1.2.2 and Oracle XE 11gR2
Hello,
I am experiencing an issue with pinging a JDBC connection Pool.
I installed the following without any warnings or errors:
Operating System: Oracle Enterprise Linux 5
Oracle XE 11gR2 (11.2.0.2.0) database
Glassfish 3.1.2.2
I will refer to the steps I did after the installations
1) In the .profile file of the OS I add the following:
JRE_HOME=/usr/java/jre1.6.0_31; export JRE_HOME
JAVA_HOME=/usr/java/jdk1.6.0_31; export JAVA_HOME
GLASSFISH_DIR=/u01/glassfish3

export PATH
LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/xe/lib; export LD_LIBRARY_PATH
. /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh
2) I copied the ojdbc6.jar to the $GLASSFISH_HOME/domains/domain1/lib
3) I login to the Glassfish admin console and created a new JDBC Connection Pool.
Pool Name: ds_orasys
Resource Type: javax.sql.DataSource
Datasource Classname: oracle.jdbc.pool.OracleDataSource
User: [myschema]
Password: [myschema password]
URL: jdbc:oracle:thin:@localhost:1521:xe
When I ping the connection pool I get the following message in the server log:
[#|2012-10-23T12:14:37.069+0300|WARNING|glassfish3.1.2|javax.enterprise.resource.resourceadapter.com.sun.enterprise.connectors.service|_ThreadID=22;_ThreadName=Thread-2;|RAR8054: Exception while creating an unpooled [test] connection for pool [ ds_orasys ], Connection could not be allocated because: Invalid Oracle URL specified|#]

I tried to use different jar files. I used ojdbc6dms.jar and ojdbc14.jar.
I also copied the jar files in the $GLASSFISH_HOME/domains/domain1/lib/ext directory as some people suggested. Still no luck. I keep getting the same error messages in the server.log
Can anybody help me out or point me to the right direction.
Thank you in advanceThe error is in the URL. It was in front of my eyes and I couldn't see the error. I skipped the ':' before the '@' when I created the pool. It is working fine now.

JDBC Connection pools and clusters (is max connection for entire cluster?)
Hi,
Quick question.
When using JDBC connection pools in WAS 6.40 (SP13) in a clustered environment. Are the max connections the number
a)Each application server can use
b)The entire cluster can use
Would believe a), but I'd like it confirmed from someoneelseHi Dagfinn,
your assumption is correct. Therefore, in a cluster environment you'd need to make sure the DB can open <i>Number of nodes X max connections</i>. -
Issues with JDBC Connection Pooling
Hi all,
I'm experiencing some unexpected behaviour when trying to use JDBC Connection Pooling with my BC4J applications.
The configuraiton is -
Web Application using BC4J in local mode
Using Default Connection Stagegy
Stateless Release Mode
Retrieving Application Modules using Configuration.createRootApplicationModule( am , cf );
Returning Application Modules using Configuration.releaseRootApplicationModule( am, false );
Three application modules
AppModuleA - connects to DatabaseConnection1
AppModuleB - connects to DatabaseConnection2
AppModuleC - connects to DatabaseConnection2
My requirement is to -
Use App Module Pooling and have individual pool for each Application Module
Use JDBC Pooling and have individual pool for each Database connection
Note: All configuration was achieved in design mode (i.e. right clicking AppModule->Configurations...)
1. Initial approach -
In the configuration for each Application Module I specified the connection type as 'JDBC Datasource' and specified to approriate datasource.
Tried setting doConnecitonPooling to 'true' as well as 'false'
In the data-sources.xml I specified all the appropriate info including min-connections and max-connections.
I would expect, with the above config that BC4J would use OC4J's built in JDBC connection pooling.
2. Second approach -
In the configuration for each Application Module I specified the connection type as JDBC URL.
In the configuration I specified doConnectionPooling = 'true' as well as the max connection, max available and min available
What I experienced in both cases was that the max connections seem to be ignored as the number of connection as reported by the database (v$session) was exceeded by more than 10.
In addition to this once the load was removed the number of JDBC connecitons did not drop (I would have expected it to drop to max available connections)
My questions are -
1. When specifying to use a 'JDBC Datasource' style of connection, is it in fact OC4J that is then responsible for pooling JDBC connections? And in this case should BC4J's doConnectionPooling parameter be set to true or false?
2. Are there any known issues with the use of the JDBC Conneciton Pool as stated by the above to approaches?Thanks for the additional info. Please see my comments. below.
Sorry should have been more specififc -
1. Is each application pool using a different JDBC user? You mentioned DatabaseConnection1 and DatabaseConnection2
above; are these connections to different schemas / users? If so, BC4J will create a separate connection pool for each
JDBC user. Each connection pool will have its own maximum pool size.
Each 'DatabaseConnection' refers to a different database, actually hosted on a seperate physical server, different
schema and different user.BC4J will maintain a separate connection pool for each permutation of JDBC URL / schema. If each user is connecting
to a different DB instance then I would expect no greater than 10 DB sessions. However, if a DB instance is hosting
more than user then I would expect greater than 10 DB sessions (though still no more than 10 DB sessions per user).
2. Are all the v$session sessions related to the JDBC clients? There should be at least one additional database
session which will be related to the session that is querying v$session.
When querying the v$session table I specifically look for connections from the user in quesiton and from the machine
name in question and in doing so eliminate the database system's connections, as well as the query tools'
connection. One area I'm not sure about is the connection BC4J uses to write to its temporary tables. I am using
Stateless release mode and have not explicetly stated to save to the database but I'm wondering if it still does if so
and how does it come into the equation with max connections?BC4J's internal connections are also pooled and the limits apply as mentioned above. So, if you have specified
internal connection info for a schema which is different than the users above I would expect the additional conns.
One helpful diagnostic tool, albeit programmatic, might be to print the information about the connection pools after
your test client(s) have finished. This may be accomplished as follows:
// get a reference to the BC4J connection pool manager
import oracle.jbo.server.ConnectionPoolManagerFactory;
import oracle.jbo.server.ConnectionPoolManagerImpl;
import oracle.jbo.pool.ResourcePool;
import java.io.PrintWriter;
import java.util.Enumeration;
// get the ConnectionPoolManager. assume that it is an instance of the supplied manager
ConnectionPoolManagerImpl mgr = (ConnectionPoolManagerImpl)ConnectionPoolManagerFactory.getConnectionPoolManager();
Enumeration keys = mgr.getResourcePoolKeys();
PrintWriter pw = new PrintWriter(System.out, true);
while (keys.hasMoreElements())
Object key = keys.nextElement();
ResourcePool pool = (ResourcePool)mgr.getResourcePool(key);
System.out.println("Dumping pool statistics for pool: " + key);
pool.dumpPoolStatistics(pw);

program
that
just makes a JDBC connection to your MySQL DBMS, with no weblogic
code in the picture. When you succeed at this, show me the CLASSPATH
and
PATH of the shell that ran the program successfully, and show methe
few lines
of code that made the connection. Then we will know the problem.It
may
be that
the URL you're passing to the pool is not exactly correct for that
driver.

Hi, thanks for your assistance. Here is the log dump.You should add a 1-second login delay for the pool. (loginDelaySeconds=1).
Oracle can get swamped and ocasionally fail valid connection requests if
too many are sent in a short time, such as when a pool is being initially
populated. This setting will put a delay between successive connection
requests, and should solve the problem.

JDBC Connection pool recovery after DB server restart
I am finding that Kodo is throwing the following exception after I restart
my database server (mysql). I am doing the database server restart while my
application server is idle, so it is not during a transaction.
Communication link failure: java.net.SocketException [code=0;state=08S01]
NestedThrowables:
com.solarmetric.kodo.impl.jdbc.sql.SQLExceptionWrapper:
This is presumably due to the JDBC connection pooling. Is there a
configuration setting that allows Kodo to detect such failures and reconnect
to the database server without exposing this problem to the application
code? For example, WebLogic Server's JDBC connection pool has a setting that
enables testing a connection and recovering from such failures before
allocating it from the pool.
BenThis is presumably due to the JDBC connection pooling. Is there a

Issue while creating connection pool in weblogic using SERVICE NAME
Found two issues while creating connection pool in weblogic using SERVICE NAME
1. While running apps from jdeveloper using xxx-jdbc.xml

2. Configuriing the jndi in Weblogic server
weblogic.common.ResourceException: Could not create pool connection. The DBMS driver exception was: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

Problem
database url is generated based on SID
eg: jdbc:oracle:thin:@localhost:1521:SID
Solution
(generate seperate url for SERVICE NAME)
jdbc:oracle:thin:@localhost:1521/SERVICENAME
------------------------It is so clear: host not found error for network connection and the other SID servcie name not found means your oracle instance name is not up. check with srvctl status for given servcie name or node, else check CRS_Stat -t if you are using RAC.

When using rabbitmq-jms for vFabric RabbitMQ javax.jms.Message.getJMSDestination does not return the actual destination when it is received from a consumer listening on a Topic with a wild card. I have tested with both 1.0.3 and 1.0.5 clients with RabbitMQ 3.1.5.
I was wondering if the community was aware of this problem and if there are any workarounds? If not what is the proper channel to file a bug report. An example code snippet is below. The test fails because the TextMessageMatcher expects the destination passed in on construction (second parameter) to equal the desination on the message received (aquired from getJMSDestination).
Mockery context = new Mockery();
final MessageListener messageListener = context.mock(MessageListener.class);
final Latch latch = new LatchImpl();
final String prefix = "test" + System.currentTimeMillis();
context.checking(new Expectations() {
oneOf(messageListener).onMessage(with(new TextMessageMatcher("MSG1", prefix + ".1234")));
will(new CustomAction("release latch") {
@Override
public Object invoke(Invocation invocation) throws Throwable {
latch.unlatch();
return null;
final Connection connection = createConnection(null, null);
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
connection.start();
Topic wildcardTopic = (Topic) getInitialContext().lookup(prefix + "." + "#");
Topic destination = (Topic) getInitialContext().lookup(prefix + ".1234");
final MessageConsumer consumer = session.createConsumer(wildcardTopic);
consumer.setMessageListener(messageListener);
MessageProducer producer = session.createProducer(null);
producer.send(destination, session.createTextMessage("MSG1"));
latch.await(5000);
connection.close();
Thread.sleep(5);
context.assertIsSatisfied();Check where your MDB sends the [response] messages to.

WLS 10.0 JDBC connection pool shrink not working
We seem to be having a problem with jdbc connection pools not shrinking. In the connection pool properties in the WLS console we have:
Initial Capacity 4
Maximum Capacity 15
Shrink Frequency 900
However when I look at the underlying xml config file (see below) the last two values above are not present in the config!
Any ideas what is going on here?
thankyou,

Thanks in advance,
Adarsh RonaldHi Adarsh,
You can not create Admin MBean on managed server. Managed server can
have only cached copies of Admin MBeans with type ConfigMBean.
Could you show us what you do @ ConnectionPoolStartupWl6?
