parent process

If necessary, collect an activity and its attached error handling into a sub process to keep the parent process "cleaner. "

It has its own independent flow of control, as long as its parent process exists and the operating system supports it.

When a program forks, GDB will continue to debug the parent process and the child process will run unimpeded.

Although a parent process can access the process ID of its child process and can thus pass arguments to it, the reverse is false.

When the parent process starts compensation, the compensation services of this peer process will not be invoked.

The parent process would wait indefinitely for the child process to exit.

If a terminate end event is used in a subprocess it only causes the subprocess to be terminated, not the parent process.

This allows even running instances of the parent process to pick up newer versions of these subprocesses.

If an invoked process runs with an autonomy child, the child process takes part in the Compensation Sphere of its parent process.

The child is deleted automatically if the parent process is deleted.

A process which invokes another process with autonomy set to child is the parent process for this invoked process.

The file inheritable set is the set that can be inherited from the parent process's inheritable set into its new permitted set.

When a shell script process exits or returns to the parent process, the exit code should be 0.

This example program creates a cloned thread sharing memory space with the parent process.

If the Compensation Sphere setting is Supports, it will use the parent process's Compensation Sphere.

The downloadable code demonstrates how to create a thread that uses different account rights as the parent process.

Sets or reads the process's file mode creation mask. Child processes inherit the mask from the parent process.

Process instance ID of the parent process, or null if no parent exists.

In this study, the parent process read data from the console, write to the pipe string.

In this example, the parent process calls fork, waits for two seconds, then exits.

Child The new process is debugged after a fork. The parent process runs unimpeded.

Occurs when the default application domain's parent process exits.

Child processes inherit the mask from the parent process.

It might share the process resources with other threads that act independently (or dependently), and it dies if the parent process dies.

That is, the parent process runs in a different and independent Compensation Sphere than the peer process.

Notice that the parent process id (PPID) in the first output of ps is 8619, which is the process id (PID) of the script.

Let's now send a SIGTERM to the parent process.

In this code, 30931 is the parent process for the process 31004.

If the parent process dies before its children, the orphaned children need to know who is their parent process.

The parent process would wait indefinitely for the child process to close its

A deadlock condition can result if the parent process calls

DB2 Watchdog (db2wdog): Parent process for all other processes
