BIP Standalone 10 : JDBC & pool
hello,
I need to know how BI Publisher define a pool connection for a datasource JDBC. in witch file it's configured?
BI Publisher is deployed on Jboss
Regards
Hi ,
Can you please confirm. Datasource connection Pool is using <global-transactions-protocol>TwoPhaseCommit</global-transactions-protocol>
I think it should be <global-transactions-protocol>EmulateTwoPhaseCommit</global-transactions-protocol>.
Go to DataSouce --> Transaction to confirm. If not please change to EmulateTwoPhaseCommit and try it
Thanks

Bug in Oracle JDBC Pooling Classes - Deadlock
We are utilizing Oracle's connection caching (drivers 10.2.0.1) and have found a deadlock situation. I reviewed the code for the (drivers 10.2.0.3) and I see the same problem could happen.
I searched and have not found this problem identified anywhere. Is this something I should post to Oracle in some way (i.e. Metalink?) or is there a better forum to get this resolved?
We are utilizing an OCI driver with the following setup in the server.xml
<ResourceParams name="cmf_toolbox">
<parameter>
<name>factory</name>
<value>oracle.jdbc.pool.OracleDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>user</name>
<value>hidden</value>
</parameter>
<parameter>
<name>password</name>
<value>hidden</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:oci:@PTB2</value>
</parameter>
<parameter>
<name>connectionCachingEnabled</name>
<value>true</value>

<parameter>
<name>connectionCacheProperties</name>
<value>(InitialLimit=5,MinLimit=15,MaxLimit=75,ConnectionWaitTimeout=30,InactivityTimeout=300,AbandonedConnectionTimeout=300,ValidateConnection=false)</value>
</parameter>
</ResourceParams>
We get a deadlock situation between two threads and the exact steps are this:
1) thread1 - The OracleImplicitConnectionClassThread class is executing the runAbandonedTimeout method which will lock the OracleImplicitConnectionCache class with a synchronized block. It will then go thru additional steps and finally try to call the LogicalConnection.close method which is already locked by thread2
2) thread2 - This thread is doing a standard .close() on the Logical Connection and when it does this it obtains a lock on the LogicalConnection class. This thread then goes through additional steps till it gets to a point in the OracleImplicitConnectionCache class where it executes the reusePooledConnection method. This method is synchronized.
Actual steps that cause deadlock:
1) thread1 locks OracleImplicitConnectionClass in runAbandonedTimeout method
2) thread2 locks LogicalConnection class in close function.
3) thread1 tries to lock the LogicalConnection and is unable to do this, waits for lock
4) thread2 tries to lock the OracleImplicitConnectionClass and waits for lock.

The consequence of using this option was not a graceful degradation in performance but a complete lockup of the application. The scenario in which we created a moderate number of abandoned connections was a rare error scenario but a valid test.
How could this not be a bug in the Oracle driver? Is dead-lock a desireable outcome of using an option? Is dead-lock ever an acceptable consequence of using a feature as documented?
Turns out other Oracle options to recover from an unexpected error also incur a similar deadlock (TimeToLiveTimeout).
I did a code review of the decompiled drivers and it clearly shows the issue, confirming the original report of this issue. Perhaps you have evidence to the contrary or better evidence to support your statement "not a bug in Oracle"?
Perhaps you are one of the very few people who have not experience problems with Oracle drivers? I've been using Oracle since 7.3.4 and it seems that I have always been working around Oracle JDBC driver problems.
We are using Tomcat with the OracleDataSourceFactory. -
Hi ,
I tried to create an oracle pool by admin server. When I tried to ping it I got an error something like the cache name is already used.
When I tried to use it in my code I got another error :
'java.lang.ClassCastException: com.sun.gjc.spi.DataSource cannot be cast to oracle.jdbc.pool.OracleDataSource'
The pool properties I used are :
Url : dbc:oracle:thin:@servername:port:dbname
DataSourceName: OracleDataSource
ConnectionCacheName: cache2
ConnectionCachingEnabled: true
The code I used to get the connection :
OracleDataSource poolConnDs = null;
Connection poolConn = null;
try{
InitialContext jdbcContext = new InitialContext();
poolConnDs = (OracleDataSource)jdbcContext.lookup("java:comp/env/jdbc/jndi_pool_name");
poolConn = poolConnDs.getConnection();
ResultSet res = poolConn.createStatement().executeQuery("Select * from my_table");
}catch(Exception e){
e.printStackTrace();
}finally{
try{
poolConn.close();
}catch(Exception e){
e.printStackTrace();
Can anybody help me ??
Thanx in advanceYou should not be using com.sun.appserv.jdbc.DataSource in your code.
Neither OracleDataSource.
Change your code from
"poolConnDs = (OracleDataSource)jdbcContext.lookup("java:comp/env/jdbc/jndi_pool_name");"
to
"poolConnDs = (javax.sql.DataSource)jdbcContext.lookup("java:comp/env/jdbc/jndi_pool_name");"
Hope this works.
Thanks,

Dear Forum Users,
Can you please have a look at the following situation;
- There's is an existing PDF file in a document management system, which is accessible by an hyperlink like; http://www.localhost.nl/drawing.pdf
- I have the location in my XML dataset, now i would like to merge this file with my new document generated with BIP standalone in OBIEE.
I found a similiar solution for an external image;
<fo:external-graphic src="http://oracleimg.com/admin/images/ocom/hp/oralogo_small.gif"/>
this is working only for images not for pdf. I looked for a solution for BIP standalone but found Apache FOP (http://www.jeremias-maerki.ch/development/fop/index.html);
<fo:external-graphic src="my-doc.pdf#page=1"/>
<fox:external-document src="my-doc.pdf"/>
This is something which is not in de BIP standalone version?
Do you have any suggestions to solve this problem?

Number of connections in a JDBC pool
Hi,
I am running Sun One Webserver 6.1SP4 on Solaris 8 on sparc machines. My web app interacts with Oracle 9.2 using the web server's jdbc pooling mechanism. Everything works fine, but what worries me is the number of connections always goes up even during nights when the traffic is considerably low compared to day time. Here is part of my server.xml relevant to the pool.
<JDBCCONNECTIONPOOL name="spfc-dbp1" datasourceclassname="oracle.jdbc.pool.OracleDataSource" steadypoolsize="8" maxpoo
lsize="80" poolresizequantity="8" idletimeout="300" maxwaittime="10000" connectionvalidationrequired="on" connectionvalidati
onmethod="auto-commit" validationtablename="" failallconnections="off" transactionisolationlevel="read-committed" isolationl
evelguaranteed="on">
I checked all my code to make sure I am calling close() on result sets, statements and the connection itself both immediately after completing work as well as in the finally blocks.
The only mechanism I have to bring down the number of connections is to restart the web server. I played around with the poolresizequantity, idletimeout properties, but it didn't help much.
I thank all of you in advance for any insights.
-SharmaHi Sharma,
I have a similar problem.
Starting my portal and it works for about ten minutes. Then it is unreachable, because of an ProfileException error. I guess it is too many DB Connections.
I can do 2 things:
- wait for about 20minutes and it works again for ten minutes, or
- restart tomcat.
Currently I am setting up a new Connection Pool, Jdbc2Pool.
Did you find a solution to your problem?
Ciao,

When I just reset db listener everything works ok for next 1-2 hours (depends on application load). So temporary solution is to run bat script from windows scheduler to reset the listener every 1h.
I tried everything I could find - applied these parameters:
- Sqlnet.ora:
SQLNET.INBOUND_CONNECT_TIMEOUT=180
SQLNET.EXPIRE_TIME=5
- Listener.ora:
INBOUND_CONNECT_TIMEOUT_LISTENER_IPC=120
But still without successIs the problem here just that you need a connection pool that closes idle connections? Some pools will close idle connections after a time out period. And the pool lets you set that time out period. If the pool you are using doesn't provide that then use a different pool.

Which BC4J / JDBC pooling configurations are global for a JVM?
There are several documents and postings saying that some of the BC4J / JDBC Pooling properties are unique for the JVM.
So if i have 3 WAR files with 3 different settings in bc4j.xcfg (transaction factory, pooling settings) some of the settings are ignored after the first AM Pool is instanciated. This could be the reason for some "unreproducable" problems we have.
So please provide us a list, which properties additional to the ones below are global per JVM and which are really used from the bc4j.xcfg.
1. Getting the Connection object out of ApplicationModule says about the TransactionFactory
Please not that this property is a static BC4J property. Meaning that the value of this property when the first ApplicationModule is created is the value which will be used. If you have multiple ApplicationPool(s) then it is necessary to define the property in all configurations, dynamically, or as a system property.
2. http://www.oracle.com/technology/products/jdev/tips/muench/ampooling/index.html says about jbo.ampool.monitorsleepinterval
Since there is only a single application monitor pool monitor per Java VM, the value that will effectively be used for the AM pool monitor polling interval will be the value found in the AM configuration read by the first AM pool that gets created. To make sure this value is set in a predictable way, it is best practice for all application modules to use the same Pool Polling Interval value.
and
3. Since the tuning parameters for all ADF database connection pools - regardless of <JDBCURL,Username> value - will be set based on the parameters found in the configuration for the first AM pool that is created. To insure the most predictable behavior, it is best practice to leave the values of the parameters in the Connnection Pooling section of the Pooling and Scalability tab at their default values - so that no entry for them is written into the bc4j.xcfg file - and to instead set the desired values for the database connection pooling tuning parameters as Java System Parameters in your J2EE container.
Sounds like this means the parameters: jbo.initpoolsize, jbo.maxpoolsize, jbo.poolmonitorsleepinterval, jbo.poolmaxavailablesize, jbo.poolminavailablesize, jbo.poolmaxinactiveage ?
4. And http://oracle-web.petersons.com/bc4jdoc/bc_aappmodpooling.htm tells There is one connection pool manager for each business logic tier's Java VM. Connections remain in the pool until the Java VM stops running.
Thanks, MarkusJust another funny observation regarding BC4J parameter settings in 9.0.5.2:
Setting jbo.ampool.sessioncookiefactoryclass in the jboserver.properties is ignored. Setting in bc4j.xcfg works.

RüdigerTwo thoughts.
The first is that 10.2.0.1 is unpatched. Why? It has been two years since its release and no one has applied 10.2.0.2, 10.2.0.3 or 10.2.0.4.
The second is that your question is not a database question but a Java question is you are more likely to get an answer that will help you if you post in a group where it is on-topic. -

You didn't post the part of the stacktrace that shows the line number that the problem occured on. (Truncated. see log file for complete stacktrace)
Are you sure the problem occured in the code you posted? If so did this line execute and print on the console?
System.out.println("see?");That error can occur when the code used to deserialize an object uses a different version of the class than the version it was serialized with. The code you posted doesn't shown anything that appears to do any deserialization.
Have their been any changes to the environment lately? Upgrades to Java version, WebLogic or the JDBC driver? -
Connection Pool using weblogic.jdbc.pool.Driver

java.lang.ClassNotFoundException: weblogic.jdbc.pool.Driver
The path c:\weblogic\classes which contains this driver is specified in the

then weblogic server fails to start at all (with an error message). I would
appreciate any help !

Getting SSL Certificates to JDBC Pool
Is it possible to make container managed JDBC-pool with proxy authentication to Oracle Database using certificate obtained from request object?
I mean, define a connection factory for oracle database and supply at configuration time that certificate proxy property should be taken from request object?
Is it possible or it is theoritically wrong to use that scheme?Is it possible to make container managed JDBC-pool with proxy authentication to Oracle Database using certificate obtained from request object?

Web Logic 6.1 JDBC Pooling with the Oracle Thin Driver
Hi,
We're slowly getting through a WebLogic 4.5.1 to 6.1 conversion for a small application
at my company. Initially, we had trouble getting the Oracle thin driver working.
We've finally cracked this nut. Now we're trying to get pooling working, and
cannot find an example of doing this with the Oracle thin driver.
Would anyone be able to provide:
1. the portion of the config.xml that pertains to building a connection pool using
the Oracle thin driver
2. the two lines of code for loading the driver and getting a connection from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Thanks very much!

You don't usually edit the config.xml unless it is absolutely necessar. Instead,
you can config the pool in the GUI admin console, quite easily. After you successfully
configed the pool in the console, it is written into the config.xml file for you.
Only thing special when config the pool is the name of the driver and the url.
url: jdbc:oracle:thin@dbhost:dbport:dbinstance
driver: oracle.jdbc.driver.OracleDriver
If you prefer, you can also config the pool from the command line. It is detailed
in the "Weblogic Server Command-line Interface Reference".
2. the two lines of code for loading the driver and getting a connection
from
this pool
i.e.
Driver d = (Driver)Class.forName("weblogic.jdbc.pool.Driver").newInstance();
Connection c = d.connect("jdbc:weblogic:pool:myPool", null);
Again, you don't use the connection directly. Instead, you use "Data Source".
Data source in weblogic is just a connection object factory associated with a
JNDI name. You can therefore lookup the data source with the JNDI name and from
the data source object, you get the connectin object. No need to explicitly load
the driver class.
There are plenty of example codes available in the weblogic examples installed
with 6.1, that uses the data source.

Java.lang.StringIndexOutOfBoundsException when trying to create a JDBC pool connection.
Hi, I get a java.lang.StringIndexOutOfBoundsException when making a JDBC
pool connection via the console of WLS 7.0. I use SQL Server 2000 in Win2K
SP2 environment. Exactly the same configuration works perfectly in WinXP
Pro. Can anyone advise me what might cause this problem? Thanks a lot.

show us your pool definitions from the config.xml file. There's
probably a

with the URL or properties.

Slow performance WLS with jdbc pools
Hi all, we have follow configuration of our system: the server with applications and server with jdbc pools. Recently we get strange situation. The server with jdbc pools it seems hung. We get thread dumps for this server and we see that it not hung, but normally work but very slow. Many weblogic.kernel.Default threads were busy by rmi database calls (see below). Anothe strange that before slowing server work nothing enties in server log. Last entry in server log were one hour before slow work. May someone propose why this situation can occure?

-- end of trace</b>Hi. It seems you're doing JDBC in an external client, using our RMI-based
JDBC wrappers to the actual connection in the WLS server, and you are
doing LOB retrieval. This means your query goes from your client to
the WLS process, and then to the DBMS, and the LOB data (big) has to go
from the DBMS to the WLS process and then back over RMI to your client.
This is bound to be inefficient. If you can move your JDBC to a JSP or
other serverside class, it will be much faster. Otherwise, if the
management that WLS provides is not strictly necessary for the LOB
manipulation, it may be faster to get that directly from the DBMS to
the external client by using the vendor's JDBC driver directly.
