Dry Run installation test routine
With the Dry Run RCCMD offers a unique function within the VMware settings:
The Dry Run is a simulation mode, in which your RCCMD
installations simulate the behavior, but do not physically execute.
This feature is useful when installing an RCCMD installation on a
production server:
Accidental shutdown is prevented in this way. With Save and
Execute, this feature is enabled, protecting your future
configuration from accidental shutdown.
Note
Some configuration menus are locked during testing and cannot be adjusted "in between".
What a „Dry run“ does …
Normally, a CS141 is the RCCMD server that sends a valid RCCMD command to an RCCMD client - the RCCMD software. The
command and what to trigger with it depends on the final operating scenario. Due to the fact you can use the event handling
from the CS141 for sending individual commands in order to start very delicate and complex scripts, it is possible to automate a
server via scripts in many parts - you do not necessarily just have to shut down a server with RCCMD.
With VMware, the RCCMD appliance differs from normal client installation:
It is designed to ensure a structured shut down sequence for all hosts within a VMware environment-
To fulfill this task, RCMMD needs access data coming with system rights to allow a shutdown. The problem that RCCMD cannot
differ between a real emergency situation and a user who press the test job - button at CS141. During testing, this is could be a
problem. As soon as RCCMD will accept a valid signal, it will start the shutdown procedure - It is comparable with the quiet "OK"
- console command of any normally shown „Are you sure " - Dialog inside an operating system.
Of course, you cannot simply shut down "all servers" during operation because you want to test your configuration - shutting
down a real-time system with 100% availability is just for real emergency issues....
