Error description

  • When a message flow node first gets an ODBC database connection,
    it interrogates the database for information such as what data
    types are supported. If between making the initial connection
    and requesting the supported data type information the
    connection to the database is lost, the integration server may
    abend. If the abend file contains a call stack, the following
    methods will be seen near the top:
    
    ImbOdbcConnectionInfo::supportsDatatype
    ImbOdbcConnectionInfo::gatherTypeInformation
    
    This is more likely to occur when using the option to "Connect
    before flow starts" on the data source node, and the connection
    has been killed from the database side or by the network for
    being idle for too long.

    PROBLEM DESCRIPTION:
    When a message flow node first gets an ODBC database connection,
    it interrogates the database for information such as what data
    types are supported. If between making the initial connection
    and requesting the supported data type information the
    connection to the database is lost, the integration server may
    abend. If the abend file contains a call stack, the following
    methods will be seen near the top:
    
    ImbOdbcConnectionInfo::supportsDatatype
    ImbOdbcConnectionInfo::gatherTypeInformation
    
    The error handling is not checking whether a failure to obtain
    information from the database is due to the connection being
    lost, and it continues to use the invalid database connection
    handle.
    
    This is more likely to occur when using the option to "Connect
    before flow starts" on the data source node, and the connection
    has been killed from the database side or by the network for
    being idle for too long.
    

Problem conclusion

  • The product now checks whether any database errors when
    gathering type information are due to the database connection
    being lost, and if that is the case an exception is now thrown.
