Initializing and Configuring TMF
•
RDFUPDO. RDF updater programs open image files in privileged mode and must
be licensed with FUP or by running the RDFINST macro. RDFUPDO also must be
able to open database files for protected write access. When querying the backup
database files, users should always open the files for shared read access.
•
RDIMAGE. The RDIMAGE program opens the image files in privileged mode and
must be licensed with FUP or by running the RDFINST macro. RDIMAGE can be
owned by any user ID. RDIMAGE must be run by a member of the super-user
group (user ID 255,nnn) to read the image files.
Initializing and Configuring TMF
After copying the appropriate files from the primary system to the backup system, you
must ensure that TMF is configured on both systems to support RDF operations. The
actions you take to do this depend on whether or not TMF was running previously on
this system.
TMF Subsystem Not Running Previously
If TMF was not running previously on the primary system, after you have installed TMF
you should take the following steps:
1. Include the following commands in the TMF configuration OBEY command file:
START TMF, DISABLE BEGINTRANS
DISABLE AUDITDUMP MAT
Although not required by RDF, it is recommended that you start TMF with
transaction processing turned off, and then turn it on after the RDF subsystem is
started. Doing so assures you that RDF is fully operational before transaction
processing begins.
The DISABLE AUDITDUMP command ensures that TMF does not purge any audit
trail files before RDF extracts all pertinent data from them.
2. Initiate a TMFCOM session and then execute the TMF configuration OBEY
command file.
If TMF was not running previously on the backup system, after you have installed TMF
you must use TMFCOM to issue a START TMF command and one or more ADD
DATAVOLS commands to add to the TMF configuration all disk volumes to be used by
the RDF updater processes.
Note. You should not restart the applications until RDF has been installed, initialized, started,
and transaction processing in the primary system has been turned on (by issuing a TMFCOM
ENABLE BEGINTRANS command).
