AnswerIn Solaris, you need to disconnect your program from your "terminal" ( scripts generally inherit the stdin, stdout, and stderr of your shell when you execute them ). For a shell program you can execute "nohup $program < /dev/null > /dev/null 2>&1 &". Or the shell program can redirect its own stdin, stdout, and stderr -- then you can execute "nohup $program &".

How to write daemons using threads instead of using fork as there are certain conditions in which a process is called a daemon?
A "daemon" is a general English term for a process that is meant to run forever in the background, without access to a display terminal. Threads are subcomponents of processes. It is not possible to run as an isolated "thread". Every process contains at least one thread, but can contain more if programmed correctly. Threaded programming typically is done so that a master or "manager" thread listens for an indication of incoming work to be done, and then dispatches this work to a new "worker" thread to handle the work, freeing the manager thread to listen for more incoming work.
Is main method a thread?
No, Main is not a daemon thread in Java. its a non daemon or user thread. Also any thread stem from Main will be non daemon because daemon is derived from parent Thread status.
What is daemon thread in java?
Daemon thread is a kind of thread that does not prevent the JVM from exiting when the thread is still running while the program finishes. A good example of this is the garbage collection.
What is a daemon thread?
A daemon thread is often called a "service thread" or a "nonessential thread". The other kind of thread is often called a "user thread."The JVM will exit when all user threads have returned from their run methods. Once all of the user threads have returned, any active daemon threads will be forced to stop running.Let's look at an abstract example to see the difference... Pretend you have written a client-server GUI-based chat client. You'll typically have at least one thread sitting around and listening for input from the other program (the server will listen for input from the client and the client will listen for input from the server). These threads can be set as daemon threads, because you don't want the JVM to keep executing if those are the only threads left.Not let's look at the GUI for your programs. These will be run in a user thread, since you want to make sure that the JVM does not exit until the GUI thread finishes running (you will generally stop these threads from running when the user clicks to close the window).
Why is the haber process not run at a high pressure?
because in this process a mixture of nitrogen and hydrogen is heated at 400 to 450c
What are the features of daemon thread in java?
Any Java thread can be a daemon thread. Daemon threads are service providers for other threads running in the same process as the daemon thread. For example, the HotJava browser uses up to four daemon threads named "Image Fetcher" to fetch images from the file system or network for any thread that needs one. The run() method for a daemon thread is typically an infinite loop that waits for a service request. When the only remaining threads in a process are daemon threads, the interpreter exits. This makes sense because when only daemon threads remain, there is no other thread for which a daemon thread can provide a service. To specify that a thread is a daemon thread, call the setDaemon() method with the argument true. To determine if a thread is a daemon thread, use the accessor method isDaemon().
What is a difference between a daemon and a background process?
Background processes are tied to a terminal's job control, while a daemon runs headless. When the terminal is killed or the user is logged out, the process dies. A daemon does not need the user to be logged in.
What is Daemon Process in unix?
The word daemon is a word of Greek derivation meaning "worker". Daemon processes in Unix are background tasks that do things, such as printing, networking, task scheduling, etc.
What is deamon proscess in unix?
A daemon process is a background service, running as a disconnected process. This means it does not have a terminal interface with an output screen or a keyboard. These services run network processes, job scheduling, etc.
How does the daemon avoid getting killed when its parent process dies?
A true daemon process is disconnected from its parent, so it won't receive a kill signal if the parent dies. It becomes an independent entity after startup.
Why scr daemon is taking 99 percent of CPU utilization. Is it really needed to run or it can be killed?
No daemon should ever take that much CPU utilization. That particular daemon will do that if there are some resolution issues. See the related link for details.
What is daemond in unix?
A daemon, not daemond, is a program or server application that runs in the background, possibly started during the boot process. A daemon is analogous to what is referred to as a 'service' in the Windows world.
Where can you purchase Daemon tools?
Daemon Tools can be purchased at Daemon's official website.
In UNIX terminolgy a listener process that operates on a server to handle incoming requests for services is called a what?
Daemon
