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

11 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 Chapter 16 (page 307).
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
