Preparing the Backup System
For SQL/MP databases, you need copies of the following objects on the backup system:
•
The system catalog
•
Catalogs in which base tables protected by RDF and objects dependent on those
base tables are registered, preferably with the same names as the primary system
catalogs
•
All base tables that reside on primary system volumes protected by RDF
•
All views and indexes dependent on base tables protected by RDF
•
All program files for applications that use any base tables protected by RDF if you
want the applications to run at the backup site after an RDF takeover operation
The backup system should also have copies of the following files in case an RDF
takeover operation is necessary:
•
OBEY command files and TACL scripts containing SQL/MP DDL commands that
define the database
•
SQLCI report definitions
To make it easy to compare catalogs on the primary and backup systems, it is strongly
recommended that you register objects protected by RDF in separate catalogs from
objects not protected by RDF. Either all the tables in a catalog should be protected or
none of the tables should be protected.
Every SQL/MP object maintained on the backup system must be registered in a catalog,
even if the object is not protected by RDF.
