Steps for Moving an Enscribe Database Using RDF
2. Develop the scripts that will manually create empty files for an empty database and
that will load the files with that data.
3. From the NonStop S-series system, initialize, configure, and start RDF with
updating disabled (START RDF, UPDATE OFF).
4. Create and populate an empty version of the primary database:
•
If you have enough disk space on your NonStop S-series system to hold a
copy of the primary database, load the primary database into the empty
database on the NonStop S-series system using FUP LOAD commands with
the SHARE option. Use the BACKUP/RESTORE utilities to move the duplicate
database from the NonStop S-series system to the Integrity NonStop
NS-series system. For detailed instructions, see the procedures for online
database synchronization with Enscribe objects in the NonStop RDF/IMP,
IMPX, and ZLT System Management Manual.
•
If you do not have sufficient disk space and prefer to use a high-speed,
high-bandwidth Expand network connection, create your empty database on
the Integrity NonStop NS-series system and use FUP LOAD commands with
the SHARE option to populate the empty database with the primary database
records over the network. For detailed instructions, see the procedures for
online database synchronization with Enscribe objects in the NonStop
RDF/IMP, IMPX, and ZLT System Management Manual.
5. After the database copy is installed on the Integrity NonStop NS-series system,
start RDF updating. RDF reads the audit changes that have been made to the
primary database since the start of the FUP LOAD operations and applies these
changes to the backup database on the Integrity NonStop NS-series system.
When RDF finishes applying these audit trail changes, it reports that the primary
and backup databases are synchronized.
6. After you have completed testing and evaluating the backup database, make the
Integrity NonStop NS-series system the primary database and start running
production applications from it.
Note. While the Integrity NonStop NS-series system is the backup database, run only
read-only applications on that system to prevent any changes that are independent of the
primary database.
