Setting Global Attributes; Logfile Attribute; Updaterdelay Attribute - HP NonStop RDF J-series RVUs Management Manual

NOTE: Instead of issuing SET and ADD commands interactively within an RDFCOM session,
you can create and execute an RDF configuration command file. The first time you configure
RDF, you can either configure it interactively or use the text editor to create a command file.
After you have configured RDF, you can easily create a command file from the existing
configuration file as explained in
then use that command file whenever you need to reconfigure RDF. See
for a sample configuration file.

Setting Global Attributes

The SET RDF command establishes values for global attributes that apply either to the entire
RDF system or to all updater processes. These attributes and their default values are:
• LOGFILE
• UPDATERDELAY
• UPDATERTXTIME
• UPDATERRTDWARNING
• UPDATEROPEN
• SOFTWARELOC
• NETWORK
• NETWORKMASTER
• UPDATEREXCEPTION
• LOCKSTEPVOL
• REPLICATEPURGE
• REMOTE MIRROR
• REMOTE STANDBY
• OWNER

LOGFILE Attribute

The LOGFILE attribute specifies the name of the EMS collector to which all RDF command,
event, error, and warning messages are to be directed.
The following commands specify the EMS collector $CTD25 as the RDF log file on both the
primary and backup systems:
]SET RDF LOGFILE $CTD25
]ADD RDF
The collector on the primary system receives log messages from the extractor and monitor
processes (plus RDFCOM messages that are logged in message 835).
The collector on the backup system receives log messages from the receiver, purger, and all
updater processes (plus RDFCOM messages that are logged in message 835).

UPDATERDELAY Attribute

The UPDATERDELAY attribute specifies how many seconds (from 1 to 10) the updater processes
should delay upon reaching the logical EOF in the image trail before checking to see if logical
EOF has advanced. The default is 10 seconds.
This attribute should be left at the default value unless you have a very specific reason for lowering
it; lowering the UPDATERDELAY value could adversely impact updater performance.
