13. The author thinks that congestion control of computer networks has much inherent property of distributed control system. Intuitively, the framework of explicit rate-based flow control defined in TM4.0 is modeled as the first order system with delay. Regarding the queue length as control object...
comes to writing data to the queue files, care-full consideration must be taken when closing the files, because on most OS’s a close of the file, will force any data that has been appended to the file, to be flushed to disk, and if we are not careful this could stall your ...
'-' - the task has beenexecuted (done)(a task is removed from the queue after it has been executed, so this value will rarely be seen) '!' - the task isburied(disabled temporarily until further changes) '~' - the task isdelayedfor some time. ...
The message is not automatically deleted from the queue, but after it has been retrieved, it is not visible to other clients for the time interval specified by the visibility_timeout parameter. If the key-encryption-key or resolver field is set on the local ...
After the AddJob method has been called, you must write a Byte array to the JobStream property of the PrintSystemJobInfo that is returned by AddJob or no print job is created. This array is what prints if the printer is working and is not paused. Caution If the JobStream is not clos...

A port has a hard-coded base buffer value allocated it which can be scaled by the user or system (but the base number can not be changed, which is important to understand how to predict outcomes) The base buffer value for a given port type depends on specific co...
Specifies the behavior of an MQPUT when the target queue has both a local instance and at least one remote cluster instance. If the put originates from a cluster channel then this attribute does not apply. The possible values are: *SAME The attribute is unchanged. *QMGR The value is...
