Installing and Configuring RDF
After preparing your system configurations and user applications to meet RDF
requirements, you are ready to install and configure RDF. This section, which is
intended for system managers, system analysts, and database administrators, describes
how to do these tasks.
The procedures described in this section require that your business applications already
be operational on the primary system, all important database files already be protected
by TMF, the necessary Expand lines already exist between the primary and backup
systems, and the backup system include all necessary disk volumes.
Installing and configuring RDF involves these steps:
•
Preparing the primary system by stopping the applications and TMF on this system
•
Copying the database files from the primary to the backup system
•
Installing the RDF software on both systems
•
Configuring TMF on the primary and backup systems
•
Initializing and configuring RDF on the primary system
•
Enabling RDF operations by restarting TMF, starting RDF, and restarting the
applications on the primary system
Preparing the Primary System
Before installing RDF, you must perform the following operations at the primary
system:
1. Stop the necessary software in this order:
a. Stop all applications being protected by TMF.
b. Stop TMF.
2. Prepare your SQL/MP tables and Enscribe files for RDF protection as follows:
a. Separate the tables to be protected by RDF from the tables not to be protected.
(This step is recommended but not required.)
b. Set audit compression (the AUDITCOMPRESS file attribute) on for all tables
and files to be protected by RDF. Note that audit compression on is the creation
default for SQL/MP tables and indexes. Although not required by RDF, audit
compression will enhance RDF performance.
Stopping the Software
After you stop all applications protected by TMF, stop TMF itself by issuing a STOP
TMF command through the TMFCOM interactive interface. For information about
issuing this and other TMFCOM commands, see the NonStop™ TM/MP Reference
Manual.
