Where Issued
Where Issued
Some RDFCOM commands can be issued only from the primary system, others only
from the backup system, and still others from either system. For each command, the
allowed systems are listed under “Where Issued.” For your convenience, they are also
summarized in Table 8-1.
Security Restrictions
Although several RDFCOM commands are available to all users, other commands
impact the overall RDF environment and are, by default, restricted to members of the
super-user group. For each command, the default security requirements appear under
the heading “Security Restrictions.” In general, the default security restrictions for
RDFCOM commands are as follows:
•
The EXIT, FC, HELP, HISTORY, INFO, OBEY, OPEN, OUT, SHOW, and STATUS
commands can be used by all users.
•
The START RDF and TAKEOVER commands can only be used by the member of
the super-user group who initialized RDF.
•
The other RDFCOM commands can be used only by members of the super-user
group.
The default security restrictions for all RDFCOM commands are summarized in
Table 8-2, Default User Security for RDFCOM Commands.
RDF State Requirement
Some RDFCOM commands can only be entered after RDF has been started; others
must be entered before the subsystem has been started or after it has been stopped.
In each command description, these constraints are listed under the heading “RDF
State Requirement.”
Usage Guidelines
Details about the proper use of a command appear under “Usage Guidelines.” These
details include information about when to apply the command, possible constraints and
unexpected effects of the command, hints on enhancing performance and avoiding
errors, and other considerations.
When a command is extremely basic or straightforward, the command description
omits the “Usage Guidelines.”
