SOA 11.1.1.3.0 - Connection Pool has been suspended during weak load

Hi,
I have a SCA with different BPEL, all uses several db adapters.
Each db adapter has retry count set to 1.
Each bpel has the following properties:
    <property name="bpel.config.transaction" many="false">required</property>
    <property name="bpel.config.inMemoryOptimization">true</property>
    <property name="bpel.config.completionPersistPolicy">off</property>When I do a simple load testing (with 10 concurrent threads invoking the same SCA webservice) my connection pool is suspended.
Here is my connection pool configuration:

Also, the strange thing is that if I monitor the Datasource (that has a 100 conn. capacity) I see that it is not overloaded:

  • New error with upgrade jboss/tomcat: "Connection handle has been closed and is unusable"

    Hi,
    This error suddenly appeared when we upgraded from jboss3/tomcat5.0 to jboss4.2/tomcat5.5.
    here's the usecase:
    1) User clicks on report link
    2) Crystal reports web componnent displays screen to fill in report parameters.
    3) user enters parameters and clicks submit
    4) System throws Exception
    The same reports worked fine with jboss 3.2.6/tomcat 5.0. We haven't touched anything in this realm.
    Log Excerpt:
    09:42:18,842 INFO  [datasource] Openning rowset
    09:42:18,904 ERROR [reportdefinition] com.crystaldecisions.reports.queryengine.driverImpl.m: JDBC Error: Connection handle has been closed and is unusable

    com.crystaldecisions.reports.reportdefinition.datainterface.g: JDBC Error: Connection handle has been closed and is unusable
         at com.crystaldecisions.reports.reportdefinition.datainterface.d.a(Unknown Source)
    To try to narrow down the problem, I've updated the jdbc configuration to
         <track-statements>true</track-statements>   
    here's a recap:
    This Boolean element specifies whether to check for unclosed statements when a connection is returned to the pool. If it is true, a warning message is issued for each unclosed statement. If the log4j category org.jboss.resource.adapter.jdbc.WrappedConnection has trace level enabled, a stack trace of the connection close call is logged as well. This is a debug feature that can be turned off in production.
    Interestingly enough, this error appears slightly upstream:

    So the question arises:
    1) Is the jboss datasource overly/aggressively closing result sets?
    2) or is there a coding error in CRXIR2?
    thanks,

    <p>
    OK. I found the problem along with a workaround.
    </p>
    <p>
    <strong>The problem:</strong>
    </p>
    <p>
    a programming practice clashes with a new jboss 'safety check'.
    </p>
    <p>
    <strong>Programming practice:</strong>
    </p>
    <p>
    crystal reports gets a database connection in one jsp page, then tries to use it on another jsp/servlet
    </p>
    <p>
    <strong>Jboss safety check:</strong>
    Jboss/tomcat new comes configured out-of-the-box with a 'cached connection
    manager', which
    </p>
    <p>
    "Check[s] for unclosed connections and transaction terminated checks in servlets/jsps."
    </p>
    <p>
    <strong> Summary</strong>
    </p>
    <p>
    In short, if a servlet/jsp ends and it leaves a database connection open, Jboss will automatically close it.
    </p>
    <p>
    </p>
    <p>
    <strong>Workaround:</strong><br />
    Comment out two entries in these two files:
    </p>
    <p>
    1) conf/jboss4/pe/deploy/jboss-web.deployer/server.xml
    </p>
    <p>
    2) conf/jboss4/pe/deploy/jboss-web.deployer/META-INF/jboss-service.xml
    </p>
    <p>
    The two entries:
    </p>
    <p>
    </p>
    <p>
    1)
    </p>
    <p>
                 <Valve className="org.jboss.web.tomcat.service.jca.CachedConnectionValve"<br />
                    cachedConnectionManagerObjectName="jboss.jca:service=CachedConnectionManager"<br />
                    transactionManagerObjectName="jboss:service=TransactionManager" /><br />
    </p>
    <p>
    2)
    </p>
    <p>
          <depends>jboss.jca:service=CachedConnectionManager</depends><br />
    </p>
    <p>
    </p>
    <p>
    <strong>Comments on the workaround</strong>
    </p>
    <p>
    The 'cached connection manager' basically makes sure that the application cleans up after bad programmers. It seems most helpful in development, load testing, or trouble shooting.
    </p>
    <p>
    In production,  you can likely  comment them out with minimal
    impact on the application.
    </p>

    I don't get it, whats happening ? why does the adapter care what i am running inside a custom sql step. all it is supposed to do is execute the sql and return the values. Why is it forcing me to rewrite the operation which was working before ?

    well as always...nothing works like restart of the server. Issue resolved.

  • SOA Suite 11g - Connection Pools constantly getting suspended...

    Hi,
    I have composites, bpel processes using database adapters.
    *I keep getting "+Pool mds-owsm is Suspended, cannot allocate resources to applications+"  and " Pool SOALocalTxDataSource is Suspended, cannot allocate resources to applications.." in soa_server logg.*
    There are no errors in db trace logs. It seems related to the WLS JDBC data sources, they are constantly getting suspended.
    After a while no new connections can be created, and managed soa server hangs. Restart is the only "solution" for now...
    I have increased "Maximum Capacity" on the connection pool to 300 without success.
    Any ideas, pointers, help appreciated.

  • Something happened and I can't connect to the itunes store on my computer, it keep saying make sure ur network connection is active and try again, but I am on the internet and I do have a connection, it has been working all this time until now

    I also had my phone go into recovery mode and lost everything up until it's last back up and don't have all my son's games I downloaded for him, lost pics, new contacts that i had added.  I don't know what the big hype of the iphone really is, i guess because I am not fully aware of how to use it but I am tired of my itunes store not coming up on my computer and apple wont' help me

    Thanks for your quick response, but all of my iTunes account info is correct.  I also just discovered that I can connect with 3G and purchase apps without problems, so it's just the wifi connection (and only with iTunes store) that is giving me problems.  I have made sure I have the latest software/firmware on my Airport Express network, and my iOS devices, and everything works well on all of my devices (can even browse the itunes store and internet) until I attempt a purchase.  I can purchase with 3G but not on Wifi.  The problem arose on both my iPhone and iPad at exactly the same time!

  • Connection Pooling: how many active connections?

    Hi, everybody.
    I have a very simple question about connection pooling...
    How many active connections should a database see once a connection pool has been opened?
    I mean, it should see only one connection (the pool itself) at any time, or the number of "logical" active connections in that moment?
    Thanks for any answer.

    Sorry...
    This is the wrong forum, I posted again my question in the JDBC Forum...

  • JDBC Connection pool recovery after DB server restart

    I am finding that Kodo is throwing the following exception after I restart

    marcoHi. Read the weblogi startServer script, and the startWLS script it calls. These
    scripts build up a string which is added to the java commandline that starts
    the server, with an argument -classpath ....... Unless the driver shows up there,
    the server doesn't see it.
    However, we already include a version of the oracle thin driver. It may not be
    the best (it's old), so you will want to make sure you version gets in to the classpath
    argument ahead of our stuff, but the old driver would have been invoked...
    Therefore, I suspect your URL is not exactly correct. Please verify that this exact URL
    works in a simple standalone JDBC program using the driver you want, without any
    weblogic code in the picture.
    thanks,
    Joe

  • Connection Pooling in heavy traffic web-applications

    In a 24x7 web-app used by 3000-10000 concurrent users, what is the
    realistic number of maxmimum connections one should
    have defined in the application server's connection pool?
    The app has no caching mechanism therefore every page is a database
    hit. Does max connection of 20 make sense when at any time 1000 users
    could be using the web-app?
    Is that number dictated by the DBA or the Java app developer?
    For example, web sites like Amazon.com sure must be using connection
    pools to control access to resources. Do they define 20 max connections
    or 200 max connections to their database? Do they have multiple replicated databases, how are the databases synced up.

    If I were to rephrase this question like
    In Weblogic 7.0, if my connection pool has
    1. Minimum capacity = 10
    2. Maximum capacity = 100
    3. Capacity Increment = 1
    And say 100 users are connected to my site using all 100 connections available.
    What happens to the 101th user?
    1. Will he be waiting for the connection to be free which was held up by 100 users?
    2. Will he get a Error/Exception regarding the same?

  • Cannot create connection pool with weblogic jDriver XA for oracle

    Hi everybody,
    we have serious problems configuring the weblogic jDriver for Oracle with support
    for distributed transactions.
    Everything works fine with the non-XA driver.
    We tried the suggestions given here before like setting the environment variable
    ORACLE_SID. However, this does not change the errors we get. We use Weblgic Server
    6.1 SP2 with oracle 8.1.7 (client and server) under Windows NT.
    When attempting to create the connection pool, we get the following exception:

  • Connection pool replacement in NW

    hi,
    does anyone know if the connection pools that could be created in EP6SP2 via System Configuration->Knowledge Management->Content Management->Utilities->Connection Pool have been replaced in NW? I've noticed they are no longer available, so does anyone know if it is possible to create such a connection pool in NW and how?
    Does anyone know where the connection pool configurations are available in the system (for NW)? (for example where is dbcon_wcmdb_cm connection pool configuration file located) 
    Thank you,
    adina

    Hi Adina,
    that's not going to work on NetWeaver. Please note that the CMRepositoryManager has been rewritten to use OpenSQL statements to retrieve data from the database. These are "generic" statements that work on any database supported by NetWeaver. What happens at runtime is that the sql statement that the application (e.g. KMC) passes on to the OpenSQL implementation which runs the statement through a statement parser and based on information taken from the java dictionary it compiles a new sql statement that the underlying native database accepts. On the way back from the database to the application the inverse operations take place, e.g. native result sets are turned into OpenSQL result sets.
    Now, in 6.40 there is a restriction in the OpenSQL implementation of the j2ee engine that allows to talk OpenSQL to only one database. So even if you would configure a different dbpool pointing to your own database then that's not supported by OpenSQL, meaning that pool would only work with native SQL.
    And that's the point where the real problem comes in: the sql statements used in the 6.40 version of the CMRepMgr won't be understood by the any native database.
    So I'm very sorry to disappoint you but it won't work this way.

  • Websphere Application Server 5.1 Hangs when using Oracle Connection Pool

    I have a j2ee application that runs on WAS 5.1 ( IBM JDK 1.4 ) and Oracle 10g 10.2.0 . My customer is doing load testing with 25 virtual users and a connection pool with a max size of 10. When the test starts all 25 users attempt to get a connection, and the first 10 get a connection. At this point the application server hangs with the connection pool in allocation. This is seen in Tivoli. Each thread only needs one connection to process it's request.
    I have my own home grown connection pool which when used under this load does not experience and issue. Monitoring from Oracle's admin console I see a max of 10 sessions. The home grows connection pool does not use a WAS DataSource.
    I have configured my application to use DB2 with a WAS DataSource and the application server does not hang. Monitoring using Tivoli shows the connection pool going into allocation, but it recovers as is expected.
    Are there any known issues with the Oracle JDBC drivers when used with WAS 5.1 DataSources?
    Any direction would be helpful, as I currently thing there is an issue with Oracle's Connection Pool and the IBM JVM.
    Thanks,
    J

    just an attention call: OracleDatasource connection pool does not accept parameters such as removeAbandoned, minEvictableIdleTimeMillis, timeBetweenEvictionRunsMillis, etc, these are specific for the tomcat dbcp implementation (http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html#JDBC_Data_Sources).
