Entering RDFSCAN Commands
All RDF messages are directed to an EMS event log (collector). To examine that log,
you first use the standard EMS filter RDFFLTO to create an intermediate entry-
sequenced file copy of the RDF log, and then enter commands through the RDFSCAN
online utility.
This section, which is addressed to system managers and operators, describes the
RDFSCAN commands and their attributes. In this section, you will find:
•
An overview of the EMS event log
•
A brief description of the RDFFLTO utility
•
A brief discussion of the elements that appear in all RDFSCAN command
descriptions
•
The command descriptions themselves, presented in alphabetic order by command
name
File names entered as parameters in RDFSCAN commands are subject to the same
syntax rules as those used in RDFCOM commands. For these rules, see “File Names
and Process Identifiers” in Section 8.
About the EMS Log
The EMS log receives all messages from RDF, including those dealing with RDF startup
and shutdown, RDF events, errors, and informative data. In an RDF configuration, an
EMS log exists, and is assigned the same name, on both the primary and backup nodes.
The EMS log is specified as the global RDF parameter LOGFILE in the RDF
configuration file. At configuration time, you can either
•
Supply the name of the desired collector in a SET RDF LOGFILE command, and
add it to the configuration file with an ADD RDF command
•
Let RDF use $0 by default
At any later time, you can change the collector specified in the configuration file by
entering an ALTER RDF LOGFILE command.
You can use RDFSCAN to examine the RDF messages in the EMS log by way of an
intermediate entry-sequenced file produced by the RDFFLTO filter. You must specify
the name of the intermediate file in the RDFSCAN command that begins your session.
