AQ: Using JDBC connection

Advanced Queue using the JDBC connection gives us AN ERROR WHEN SENDING 32K QUEUES
Is it true that RAW datatypes using the Java AQ API do indeed have a limit of 32K in 8.1.6.
The workaround is to use the Java AQ API with Object payloads (BLOBs) to get around the problem.
Has anyone used any other solution for RAW data types ?
Thanks

Don't conflate the issue here.
This question is specific to SQL Command Tables.
SQL Command Tables are given the name 'Command' in Crystal, regardless of what you use in the SQL alias.
This is a very different and separate  situation from using Tables, where you can set the Crystal alias to the SQL alias.
You don't have such equivalence when using SQL Command Tables.
So you won't be able to reference Crystal aliases in SQL aliases in that situation, nor will you be able to access the SQL alias in the Command Table, without parsing the SQL query itelf.
Sincerely,

  • 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!
    Sam

    To 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.

  • 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]

  • Can not deploy a report using JDBC connection on CR2008 Server

    Hi Group,
    I have a report created with JDBC connection. When I tried to add it to CR2008 server, it gives an error - "An unexpected error has occurred ". Basically I want to add a report to a public folder via CMC. I am using adminstrator account.
    Then I thought I need to add JDBC driver into CR2008 server. so I put oracle jdbc jar into CR2008 server classpath and add JDBC connection info into CRConfig.xml. but I still got the same error.
    I also tried:
    - Change the report to use native Oracle driver rather than JDBC. The deployment succeeded (but this is not what I want)
    - Add a data source connection via Business View Manager, but no luck.
    I know how to use/change jdbc connection with programtic way, but I just want to know if I want to use built-in components in CR2008 server without any coding the reports can be deployed and managed.
    Thanks in advance.

    Hello Will,
    Crystal Reports supports connections to JDBC/JNDI out of the box, and have done so for a while, whether stand-alone or published to Enterprise.
    To specify where the server would search for the JDBC driver jar files, you'd change the classpath tag found in the CRConfig.xml file found on the machine where the Crystal Reports Page or Job Server is running. 
    For early Crystal Enterprise 10 and before, it used Java Native Interface (JNI) to start the Java process to retrieve the data from the JDBC connection.
    For later Crystal Enterprise 10 and later, it starts off a "Java Server" process, and communicates to the Crystal Reports process via CORBA TCP/IP connection.
    Commonissues that may arise:  (1) CRConfig.xml not configured properly, (2) unable to start or communicate to the "Java Server" because of permissions or firewall.
    Note that this is a separate connectivity map from using ADO or ADO.NET.
    Sincerely,
    Ted Ueda

  • ADVANCED QUEUE: USING JDBC CONNECTION -

    Advanced Queue using the JDBC connection gives us AN ERROR WHEN SENDING 32K QUEUES
    Is it true that RAW datatypes using the Java AQ API do indeed have a limit of 32K in 8.1.6.
    The workaround is to use the Java AQ API with Object payloads (BLOBs) to get around the problem.
    Has anyone used any other solution ?
    Thanks

    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.

    Hi Vishnu
    Looks like a classloader issue. BEA class loader is very tricky. Any jar added manually in classpath, will end up loading only those classes. Any imports that we have in any of those classes do not get loaded. Anyhow, coming to your point, add classes12.jar inside your portal web project Web-Inf/lib folder and see if that helps. Usually thats where we put all the JARs for 8.1 SPxx applications. If this still breaks, then remove the jar from web-inf/lib folder and add under your portal app App-Inf/lib folder. First try with app-inf/lib folder having this jar. If not then with web-inf/lib. Basically web-inf is specific to that web app only. If you have a different app having this jdbc code, then put under app-inf/lib folder. Make sure that you remove the classes12.jar that you added in classpath either in env variable or in setdomainenv.cmd file.
    When weblogic uses native OCI Drivers, it refers to jars at this location: ....\beawlp814\weblogic81\server\ext\jdbc\oracle\10g or 9g. Try using one of these jars and see if that works. Most of the times I used these jars only for oracle specific native drivers.
    Word of caution. Try to use Connection Pool and a DataSource created in weblogic console for your jdbc code. This Datasource can still use the Oracle drivers that you want (instead of BEA Weblogic wrapper oci drivers) located in above location. Use JNDI Lookup and get Datasource and then connection. This is more recommended approach with many advantages then using DriverManager approach..

  • Error while connecting to Oracle db using jdbc

    The OCI driver 7.3 requires the 7.3 OCI to be installed (this is
    part of the client required support files or RSF). The particular
