Mixed-Product Installation

RDF/IMP and IMPX are not compatible with RDF, RDF/MP, and RDF/MPX. Therefore,

if you already have any of those earlier RDF products installed, you cannot install

RDF/IMP or IMPX on just one of your systems; you must install it on both the primary

and backup systems.

The primary and backup systems need not have the same operating system SRV

installed. The only requirement is that the installed SRV on either system be at least

D46 or G06.03.

Configuring TMF for RDF Operations

TMF attempts to purge old audit trails each time it rolls over to a new one. The purge

operation is successful only if the audit trail is not pinned on behalf of RDF.

If audit dumping is disabled and TMF were to purge an audit trail before it has been

pinned, you must reinitialize RDF and resynchronize the databases.

You can, however, configure TMF with a dump process to dump audit trail files to tape

or disk. If TMF dumps audit trail files, the extractor waits until that audit trail is restored

from tape and then resumes. In that case, you do not need to reinitialize RDF or

resynchronize the databases.

TMF Configuration With Dump Process

When you configure TMF with audit dump on, that subsystem dumps an audit trail to

tape or disk before purging the audit trail. This approach is strongly recommended on

the primary system.

Note that audit trail files are pinned by the RDF extractor and TMF cannot purge

pinned files until the extractor has finished processing them. TMF will keep these files

Operating System On the primary and backup systems, the installed software release

version (SRV) of the operating system must be D46 or later or G06.03

or later.

TMF Subsystem On both the primary and backup systems, the installed SRV of the

TMF subsystem must be compatible with the installed SRV of the

operating system.

NonStop SQL On both the primary and backup systems, the installed SRV of the

NonStop SQL product must be compatible with the installed SRV of

the operating system.

Caution. The block size of a file or table on the backup system should be identical to the size

on the primary system. If the block sizes differ, you risk corrupting your backup database.
