MOPER ALADIN - A System Action Interface
The DCL command MOPER ALADIN is an interface with which unpriviledged
users can execute some system commands. There are in general the following
access restrictions:
- The user must hold the ALADIN identifier. Every member of the
ALADiN group should have this identifier granted, check with the DCL
command show proc/priv in the "Process rights:" section.
- The user must execute the command on one of the nodes owned or used by KP3:
- VSAG, VSAH, VSAO, VSAW, VSBD, VSBL, VSBZ, VSCE
- AXP604, AXP612, AXP625, AXP627
- Some subcommands are only available on VAX's, others only on AXP's !
Most of the following comands affect the whole
computing environment and not just your session. So if you don't exactly
understand what the command does, leave it alone, don't play !
To execute a command type
MOPER ALADIN <subcommand> "<parameters>"
Note, that parameters must be given in quotes if they contain blanks.
The following subcommands are available (on VAX and/or AXP):
