We've a process on AIX UNIX server which is executed by multiple uses during a day. I wish to create a log file for every time the process is executed. I wish to know how unique are PID(s) on AIX UNIX servers if I were to name the log files with <date> and <PID>?
E.g. If I create my output files having the details such as
With my limited understanding of UNIX and from what I've read on the forum https://www.unix.com/unix-advanced-expert-users/2896-obtaining-process-id-pid.html AIX system sequentially assigns a limited set of PIDs and re-utilizes them as and when processes get freed and slot is available for allocation by dispatcher.
Please suggest a suitable way to uniquely identify the process execution during the day. I am also considering adding datetime hh:mm:ss to the log name to uniquely identify the same E.g. change log file name to

$!>PID_FILES
I try to get the PID of the last process on the files called PID_FILES.
But the command stands by on the output screen. I have to tape on ENTER to get the prompt and continue .
How may I simulate this action ( tape on ENTER ).

1. If I use an software application(which connects to the database in the server) in my local pc, how many PID should be registered? Would there be PID for the session and another PID for socket connection?

Hi!
I'm facing a unique problem!
When I run a program on HPUX, it runs fine but it also produces a bunch of files of the format:
tr.<pid>.number
the contents of these files are a bunch of numbers and I know for a fact that these files are not created by the program I'm running.

Hi All,
I am getting the PID of a process using its name using the following command
in a script
mypid=`ps aux | awk '/test5/ && !/awk/ { print $2 }'`
echo PID is $mypid
The problem is the PID is not getting printed. But when i run the command directly in shell, the PID got printed.

Hi to everybody.
Is it possible to nohup a process and redirect the output to a file containing the PID?
E.g. if
nohup filename > out.nohup
associate the PID=8074 to filename, is it possible to call the output file something like out_8074.nohup instead of out.nohup? By this way it would... (0 Replies)

Hi all,
I am generating the coredump of my JBoss, and by default it puts it in to a particular directory. i.e. JBOSS_HOME/. I would like this output file to be created, lets say in /tmp/dump/.

setpgid
setpgid(2) System Calls setpgid(2)NAME
setpgid - set process group ID
SYNOPSIS
#include <sys/types.h>
#include <unistd.h>
int setpgid(pid_t pid, pid_t pgid);
DESCRIPTION
The setpgid() function sets the process group ID of the process with ID pid to pgid.
If pgid is equal to pid, the process becomes a process group leader. See intro(2) for more information on session leaders and process group
leaders.
If pgid is not equal to pid, the process becomes a member of an existing process group.
If pid is equal to 0, the process ID of the calling process is used. If pgid is equal to 0, the process specified by pid becomes a process
group leader.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The setpgid() function will fail if:
EACCES The pid argument matches the process ID of a child process of the calling process and the child process has successfully
executed one of the exec family of functions (see exec(2)).
EINVAL The pgid argument is less than (pid_t) 0 or greater than or equal to PID_MAX, or the calling process has a controlling ter-
minal that does not support job control.
EPERM The process indicated by the pid argument is a session leader.
EPERM The pid argument matches the process ID of a child process of the calling process and the child process is not in the same
session as the calling process.
EPERM The pgid argument does not match the process ID of the process indicated by the pid argument, and there is no process with
a process group ID that matches pgid in the same session as the calling process.
ESRCH The pid argument does not match the process ID of the calling process or of a child process of the calling process.
