5 Port numbers HSDP Port number Specify 8 ports beginning from the base port number in the -port argument of the hsdpsetup command. Usage precautions Notes on the virtualization platform environment This product design was based on a standard environment (an OS environment on an actual machine). In a virtualization platform environment, this product may behave differently from a standard environment due to the effect of virtualization on hardware resources, deteriorating performance caused by shared I/O, or other causes. Use this product after you have accepted the following conditions for use: Usage conditions This product has been verified to ensure that it operates without error. However, performance deterioration can occur. In addition, functions such as those to obtain CPU times might be adversely affected. For this reason, in order to use this product in a virtualization platform environment, you must conduct a full operation evaluation and performance verification of the system. Perform these checks after the system has been built, and confirm that it uses the appropriate hardware, virtualization software, guest OS, this product, and applications.

The data to be sent is not registered in the sending queue. Notes: If the query group of the sending destination is executing parallel executions, or if you have multiple destinations for openstreaminput() in the HSDPAdaptorManager class, this exception is thrown when some of the queues match the condition. In this case, the data to be sent for which the destinations were assigned successfully are registered in the sending queue.
