RDF System Management Manual for H-Series RVUs (RDF 1.8)

• ZFILEINC file
This is a key-sequenced file that stores information about transactions and files involved in
transactions that aborted on the primary system, but TMF Backout could not undo the audit
because the volumes were down. A record for each transaction and file is stored in the
ZFILEINC file. If a volume is re-enabled on the primary system and TMF Backout is able to
undo the audit data it could not previously undo, then the corresponding records are removed
from the ZFILEINC file.
The ZFILEINC file resides on the backup node and is named
$SYSTEM.control-subvolume.ZFILEINC.
• 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
“Tips for Executing Fast Business Takeover Operations” (page 39) 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.
