1 1 Subvolume-Level and File-Level Replication

By default, RDF provides volume-level protection, wherein changes to all audited files and tables
on each protected primary system data volume are replicated to an associated backup system
data volume.
RDF/IMP, IMPX, and ZLT also support subvolume-level and file-level replication. To use this
capability, you supply INCLUDE and EXCLUDE clauses when configuring updaters to identify
specific subvolumes and files you want either replicated or not replicated.
RDF/IMP, IMPX, and ZLT also allow you to be selective about what Enscribe files you want
purged. For RDF to replicate Enscribe purger operations, you must configure the global RDF
REPLCATEPURGE to ON. By itself, this means that RDF shall replicates all Enscribe purge
operations. If you want selectivity in what purge operations you want replicated, you can then
use INCLUDEPURGE and EXCLUDEPURGE clauses when you configure the updaters. Please
note that to use INCLUDEPURGE and EXCLUDEPURGE, the RDF REPLICATEPURGE attribute
must also be set to ON.
NOTE: This chapter specifically addresses the including and excluding of Enscribe and NonStop
SQL/MP database objects. The same principles, however, also apply to NonStop SQL/MX database
objects. INCLUDE and EXCLUDE clauses require the use of Guardian names. If you have an
ANSI-named NonStop SQL/MX object that you want to include or exclude, you must first obtain
the underlying Guardian name by using the MXGNAMES utility or the MXCI SHOWDDL
command as described in

INCLUDE Clauses

INCLUDE clauses explicitly designate those subvolumes, files, and tables residing on a particular
primary system data volume to be replicated. Changes to all other audited files and tables on
the particular volume are ignored.
In this example, only changes to the audited files MYSUBVOL.MYFILE, MMTEST10.FILE1, and
MMTEST10.FILE2 on $DATA01 are replicated:
SET VOLUME CPUS 1:2
SET VOLUME IMAGEVOLUME $IMAGE
SET VOLUME PRIORITY 185
SET VOLUME PROCESS $MM01
SET VOLUME UPDATEVOLUME $DATA01
SET VOLUME INCLUDE MYSUBVOL.MYFILE
SET VOLUME INCLUDE MMTEST10.FILE1
SET VOLUME INCLUDE MMTEST10.FILE2
ADD VOLUME $DATA01

EXCLUDE Clauses

EXCLUDE clauses explicitly designate those subvolumes, files, and tables residing on a particular
primary system data volume that you do not want replicated. All other audited files and tables
on the particular volume are replicated.
In this example, changes to all audited files and tables on $DATA01 are replicated, except
MMTEST10.CONC0826:
SET VOLUME CPUS 1:2
SET VOLUME IMAGEVOLUME $IMAGE
SET VOLUME PRIORITY 185
SET VOLUME PROCESS $MM01
SET VOLUME UPDATEVOLUME $DATA01
SET VOLUME EXCLUDE MMTEST10.CONC0826
ADD VOLUME $DATA01
