RDF System Management Manual for J-series and H-series RVUs (RDF 1.10)

• RDFTKOVR file
This file records whether an RDF Takeover operation has completed successfully. This file is
empty under normal circumstances (eof = 0). If, however, you have executed an RDF Takeover
operation and it completes successfully, then they key word "DONE" is written in the file by
RDF. This file can be used for executing fast business takeover operations. See “How to Plan
for the Fastest Movement of Business Operations to Your Backup System After Takeover”
(page 135) for more details.
The RDFTKOVR file resides on the backup node and is named
$SYSTEM.control-subvolume.RDFTKOVR.
• 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
$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
$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.
