Partial Database Synchronization Considerations
To load the primary partition only, issue the following command:
FUP LOAD $DATA1.TEST.PART0100, $DATA1.TEMP.PART0100,
PARTONLY,SHARE
To load the secondary partition only, issue the following command:
FUP LOAD $DATA1.TEST.PART0100, $DATA2.TEMP.PART0100,
PARTONLY,SHARE
When the load operations are finished, issue the RDFCOM STOP SYNCH command.
You can then use BACKUP and RESTORE (or FUP DUP) with the PARTONLY option
to copy the partition you need to the backup system.
Relative Files
First create a non-audited duplicate file on the primary system. Note that you must
create the entire file with all its partitions. Unlike key-sequenced files, you must load
the entire file. For example, assume the file has two partitions: $DATA1.TEST.
PART0100 (primary) and $DATA2.TEST.PART0100 (secondary). Issue the following
command:
FUP CREATE $DATA1.TEMP.PART0100,
LIKE $DATA1.TEST.PART0100, NO AUDIT
That command creates the two files $DATA1.TEMP.PART0100 (primary partition) and
$DATA2.TEMP.PART0100 (secondary partition)
You must load all the partitions of a relative file. Therefore, only one command is
possible.
FUP LOAD $DATA1.TEST.PART0100, $DATA1.TEMP.PART0100,
SHARE
When the load operation is finished, issue the RDFCOM STOP SYNCH command.
You can then use BACKUP and RESTORE (or FUP DUP) with the PARTONLY option
to copy the loaded partition you need to the backup system.
Entry-sequenced Files
There is currently no reliable mechanism to synchronize entry-sequenced files online.
Entry-sequenced files should be synchronized offline.
Unstructured Files
There is currently no reliable mechanism to synchronize unstructured files online.
Unstructured files should be synchronized offline.
