Initializing and Configuring TMF

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.
TMF Subsystem Running Previously
If TMF was running on the primary system and you have shut the TMF subsystem 
down, and if you have started TMF on the backup system and added the RDF updater 
volumes to the TMF configuration, you need not take any other steps with respect to 
TMF. Proceed to the next task, described in Initializing RDF.
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).
