5 Managing RDF
You manage the RDF environment by monitoring various things using RDFCOM
STATUS commands, the EMS log, and the ASAP product.
In managing RDF, you must sometimes react to nonroutine events and conditions that
affect the RDF operating environment, by performing a variety of special tasks and
activities. Although most of this work is not required on a regular basis, the need for it
does arise on occasion. Typically, this work involves using RDFCOM, TMFCOM (the
interactive interface to TMF), SQLCI (the NonStop SQL/MP interactive interface),
TACL (the interactive interface to the HP NonStop Kernel operating system), or FUP.
This section, which is directed to both system managers and operators, discusses the
following tasks:
•
Recovering from file system errors
•
Handling disk space problems
•
Responding to operational failures
•
Performing file recovery
•
Stopping RDF
