MPE/iX NOTES
Due to limitations in the current implementation of
MPE/iX, there are a number of limitations
in the behavior of the ps command.
• The –n name option is ignored.
• comm displays the command name using MPE name syntax (that is file.group.account). If
an INFO string is passed by the command, it is also displayed.
• nice simply displays a value indicating whether or not the process is to undergo cyclical
degradation (see the MPE/iX NOTES section of the nice(1) man page for details). If yes,
nice displays 1. If no, nice displays 0.
• vsz displays only the current stack size. It does not include data and code size.
• addr displays only the low 32 bits of the process address.
• state displays one of the following values to indicate the process state:
O Currently running process
R Running
W Waiting
Z Dead or dying process
READY Process ready to go when it gets a time slice
• args, etime, pcpu, flags, and stime are not supported. The values shown for
these specifications have no real meaning.
• wchan displays an abbreviated string indicating the reason why the process is waiting.
The following table shows these abbreviations and their full meanings:
