Turning off MMDF permanently
This is definitely a post from a "UNIX Newbie" - we have a SCO Unix machine that houses our customer database. I have been getting reports that the system starts lagging intermittently, and have managed to determine that the cause of the slowdown is a process called MMDF.
I can manually kill this process to improve system performance, but I would rather turn this off altogether since we dont use it. (As I understand it, MMDF is an email program of sorts...we dont use the Unix machine for email at all...)
Any suggestions are welcome!
(If you have any questions regarding the Unix machine, please provide instructions as to how to look up the info you need - Im still fairly new to Unix....
)

I am running Solaris 9 and wanted the CDE stopped when my users login. Can this be done by adding something to the .profile? Basically when they login they should be at the command line and have to start the CDE themselves.

mysql_waitpid
MYSQL_WAITPID(1) MySQL Database System MYSQL_WAITPID(1)
NAME
mysql_waitpid - kill process and wait for its termination
SYNOPSIS
mysql_waitpid [options] pid wait_time
DESCRIPTION
mysql_waitpid signals a process to terminate and waits for the process to exit. It uses the kill() system call and Unix signals, so it runs
on Unix and Unix-like systems.
Invoke mysql_waitpid like this:
shell> mysql_waitpid [options] pid wait_time
mysql_waitpid sends signal 0 to the process identified by pid and waits up to wait_time seconds for the process to terminate. pid and
wait_time must be positive integers.
If process termination occurs within the wait time or the process does not exist, mysql_waitpid returns 0. Otherwise, it returns 1.
If the kill() system call cannot handle signal 0, mysql_waitpid() uses signal 1 instead.
mysql_waitpid supports the following options:
o --help, -?, -I
Display a help message and exit.
o --verbose, -v
Verbose mode. Display a warning if signal 0 could not be used and signal 1 is used instead.
o --version, -V
Display version information and exit.
