In distributed real-time systems, if a task misses its deadline, an exception can be thrown. In this context, end-to-end deadline missing prediction mechanisms can reduce exception throwing because they define an estimated response time. With this estimated response time the system can carry ...

Valid value is an integer in the range 0-999 commits. Connection ID Identifies the connection of an application to a DB2 system. Valid values are: BATCH Batch job CICS CICS attach DB2CALL DB2 call facility DIST Distributed IMS IMS thread TSO/E TSO/E foreground and background UTILITY DB2 ut...
For this reason, if a callback function might block while executing, the maximum size of the thread pool must be larger than the number of available processors in the system in order to realize the maximum concurrency that the hardware supports. Ideally, a callback function should never block...
Many different styles of invocation are encompassed under the notion of oneway message passing. While some of them are more closely associated with distributed or multiprocess applications (see 1.2.2), any of them can be used in conjunction with the constructions discussed in this section. In add...
The thread is waiting because of inter-system message sending contention. WAIT-REMREQ The database access thread is in a synchronous wait (waiting for a response or a request from the originating Db2 subsystem). WAIT-REMSQL The distributed allied thread is in a synchronous wait (waiting for ...
When the system switches from one thread to another, it saves the thread context of the preempted thread and reloads the saved thread context of the next thread in the thread queue. The length of the time slice depends on the operating system and the processor. Because each time slice is...

Scheduling of threads in a multi-core system is performed using per-processor queues for each core to hold threads with fixed affinity for each core. Cores are configured to pick th
