Managing Multiple Rdf Environments From One Rdfcom Session; Controlling Multiple Rdf Environments Running On Different Nodes With A Single Obey File - HP NonStop RDF J-series RVUs Management Manual

You would execute this command as an OBEY file to your TACL prompt. For this example,
assume you have been running an RDF subsystem where \Boston is your primary system and
\SF is your backup system. You have stopped TMF and RDF, you have reinitialized and
reconfigured TMF, and you want to reinitialize, reconfigure, and restart RDF.
Recall that before you can initialize RDF you must delete the control subvolumes on both primary
and backup systems. These are executed by the first two commands in the TACL obey file above.
The next command initializes RDF, specifying that the default system (\BOSTON) is your primary
system and \SF is your backup. When RDFCOM completes this operation, the RDFCOM session
ends and TACL moves to the next RDFCOM command. This command reads in your configuration
file ($SYSTEM.BOSTON.RDFCFG) and creates the new configuration for your environment.
When the last command in the script executes, this RDFCOM session terminates and a new
RDFCOM session actually starts your newly configured RDF subsystem.
You could place all three of the RDFCOM commands in the single RDFCOM command file
$SYSTEM.BOSTON.RDFCFG, but the value of keeping the three operations executed by separate
RDFCOM sessions is this. While your RDF configuration script may not change, your initialization
command is likely to change each time you use the INITTIME option, so you may find it easier
just to edit the overall OBEY files to change the INITTIME value. Secondly, you might find it
easier to keep the START RDFCOM command as a separate operation, thereby keeping the
configuration limited to just the different configuration commands.

Managing Multiple RDF Environments from One RDFCOM Session

If you have multiple RDF subsystems running on a single node, you can manage and monitor
all of them from a single RDFCOM session. You just need to use the OPEN command to open
the specific RDF subsystem you want to manage or monitor before issuing the command. This
is best seen by an example.
Suppose you have three RDF subsystems configured and they are replicating different data to
different nodes.
RDF Subsystem FOXIIA
\FOXII ------------------> \TSII
RDF Subsystem FOXIIB
\FOXII ------------------> \PRUNE
RDF Subsystem FOXIIC
\FOXII ------------------> \PUMPKIN
Running one RDFCOM interactively, you can monitor the status of each by issuing the following
commands:
RDFCOM
] OPEN FOXIIA; STATUS RDF
] OPEN FOXIIB; STATUS RDF
] OPEN FOXIIC; STATUS RDF
Running one RDFCOM noninteractively, you can start each by issuing the following START
RDF commands:
RDFCOM FOXIIA; START RDF; STATUS RDF
RDFCOM FOXIIB; START RDF; STATUS RDF
RDFCOM FOXIIC; START RDF; STATUS RDF
As each command line in the above example ends, that specific RDFCOM session terminates
and the next line is executed.
Controlling Multiple RDF Environments Running on Different Nodes with a Single
Obey File
If you have multiple RDF subsystems running on different nodes, you can control those
subsystems from a single obey file. Consider the following environment.
