Typically, at the end of the ISR there will be a call to an RTOS function that checks for and performs the context switch. When the interrupt occurs, the CPU saves its context and jumps to the ISR. The way the context is saved varies among CPU families. When the ISR is complete, it should call a special RTOS routine that allows for a context ...

An exit routine has access to various control blocks available in the environment from which it was called. To simplify exit coding IBM-defined exit routines provide in registers 0-13 pointers to control blocks currently in main storage.

A process is a program in execution. In operating system each process is represented by process control block (PCB). It is also called as task control block.A task control block (TCB) represents a z/OS task. A running CICS system is a z/OS address space containing multiple TCBs and hence multiple z/OS tasks. Within CICS, a CICS task itself runs on a TCB. Before the open transaction environment (OTE) was implemented in CICS, CICS used a single TCB to run all user … run by the kernel. On a context switch , a task's context is saved in the Task Control Block (TCB). A task's context includes: • thread of execution, that is, the task's program counter • the CPU registers and floating-point registers if necessary • a stack of dynamic variables and return addresses of function calls The following screencast is going to demonstrate how we can inspect the process control block (struct task_struct) by connecting the debugger to the running virtual machine.
