RDF File Codes
•
ZRCVnn files
One file is created for each auxiliary receiver in your RDF configuration, and the nn
is the two-digit ATINDEX of the receiver. These files store information about SQL
Shared Access DDL operations involving files protected by RDF.
The ZRCVnn files reside on the backup node and are named
$SYSTEM.control-subvolume. ZRCVnn.
•
UNDO List files
These files contain the lists of transactions that need to be undone either during a
stop-update-to-time operation or takeover operation. They can be read with the
READLIST utility, which creates a similarly named file in the MIT that can be read
with RDFSCAN. The ZNETUNDO file only exists in RDF network environments.
The undo list files resides on the backup node and are named $master-image-
trail-volume.control-subvolume. ZTXUNDO, $master-image-trail-
volume.control-subvolume.ZFILUNDO, and $master-image-trail-
volume.control-subvolume.ZNETUNDO.
•
Network List files
These files contain the lists of transactions that need to be evaluated for possible
undo during a takeover operation if you have configured an RDF Network.
The Network list files resides on the backup node and are named $master-image-
trail-volume.control-subvolume. ZRDFLCMT, $master-image-trail-volume.control-
subvolume. ZRDFLCM2 , $master-image-trail-volume.control-
subvolume. ZRDFLCM3 , $master-image-trail-volume.control-
subvolume. ZRDFNMTX , $master-image-trail-volume.control-
subvolume. ZRDFNMT2 , and $master-image-trail-volume.control-
subvolume. ZRDFNMT3.
Each backup system of the RDF Network has its own ZRDFLCMT file. The other
files are only located in the MIT of the network master.
