Partial Database Synchronization Issues
To load the secondary partition only, issue the following command:
FUP LOAD $DATA2.TEST.PART0100, $DATA2.TEMP.PART0100,
PARTONLY,SHARE
When the load operations are finished, 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
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 and Unstructured Files
Currently there is no reliable mechanism to synchronize these file types online. Entry-
sequenced and unstructured files should be synchronized offline.
NonStop SQL/MP Tables Without Partitions
Key-sequenced Tables with SYSKEY
Because the SQLCI LOAD operation generates new SYSKEY values in the backup
table, key-sequenced tables containing SYSKEYs cannot be synchronized online.
Key-sequenced Tables without SYSKEY and Relative Tables
First create a non-audited duplicate table on the primary system and then load it. Use
BACKUP and RESTORE (or SQLCI DUP) to move the duplicate table to the backup
system.
Alternatively, you can use the create and load method to put the duplicate tables
directly onto the backup system, provided you have enough Expand capacity to handle
both the data being loaded and the audit being shipped to the backup system by the
extractor.
