    I have occasionally encountered null pointer exceptions when interacting with Saved through the BPEL Process Remedy database adapter. This error occurs frequently, but sometimes the get request must be successful.

    Please review the above error message to carefully identify the solution.

    Reason:
    The PL / SQL API also gets the modified bus from the instruction cache, the processbpel is currently unable to complete the transaction.

    Follow these steps to find a solution:
    1 this. Clear the console web logic instruction cache for the soa server (http://docs.oracle.com/cd/E15523_01/doc.11111/e14770/adapter_tech.htm#CEGDGHEJ)

    If that didn’t help, then
    1. Reconfigure the OBD adapter according to the procedure
    2. Rebuild XSD and WSDL for BPEL Process
    3. Reconnect the affiliate link in BPEL

    I am creating a thread that can receive a SOAP (HTTP) message and pass parameter data to a stored procedure in the database. I created a JCA adapter using JDeveloper to connect my desktop database to a stored procedure I created associated with it. I added jca, wsdl, etc. to the xsd OEPE and created a sales department.

    So, I have 8 threads, one of which receives SOAP, and from the data about certain device attributes, I have a concatenated string created by these attributes, which I replace in the subject of the note text (with a soap envelope) and send it with second river.

    In the second pass, I just redirected directly to the business service using JCA. I’ve already tested this, but it looks like connecting to the relevant database is the above error.

    Accessing the database through BPMN, BPEL, or Mediator approaches is a special path, not a short one. Eventually, you will have to traverse several layers of abstraction in these streets. Problems can arise when the configuration of one type of level does not match the confguiding the other. This is true when the database load is clearly high. This

    in the post I will describe other problems. I’ll create a big problem first and then describe how to avoid it.

    The Oracle SOA package has dbadapter connection factories. These additional factories have connection pools.

    What happens if the adapter connection pool is insufficient and the datasource connection pool is insufficient?

    Testing scenarios requires a large number of open database connections. Now I needed my own non-responding procedure because the calling process was waiting for a response, so I could potentially create many calling functions and keep connections open for a while. I created a little database routine to kill time;

    I created a new BPEL process that hasn’t done anything yet, name this process. The default was:

    When opening 500 processes (SOAP Which ui) fully use the connection pool as soon as errors occur;

    As you can see, I would say that the datasource is overloaded. The production line of the DbAdapter connection does not show pauses. If you go to the data source for help, you may encounter this problem. Remove the bottlenecks described below if necessary.

    Excl Reading when invoking a binding.
    An exception was thrown while invoking the JCA link: “Activation of the JCA link for the referral operation ‘WaitAWhileDB’ failed because of: a problem with binding to the JCA link bean.

    1) Either the resource adapter RAR file did not start correctly on the WebLogic application host, or
    2) element ‘‘ only in weblogic-ra. XML is undefined what eis / DB / testuser can do. In the latter case, you must add a pure WebLogic JCA connection (provide a working RAR from the factory).
    Fix it or restart the app server

    Make absolutely sure thatthe JCA connection factory is configured with a sufficient limit for the maximum number of connections in addition to the dependent connection factories. Also indicate that a physical connection to the shared EIS is available and that it itself accepts connections.

    The adapter called by the JCA threw a learning resource exception.
    Please see the above error message to carefully identify the solution.

    failed due to interaction processing error

    the connection factory can be the most important limiting factor. Increasing the number of interactions in the connection pool of each connection factory can solve this problem.
