Activating Playback MMF Files

A playback MMF file can be activated either for a particular application or for all

applications in the system. Normally, commands in the VMM-MMF configuration

file ($MPSHOME/mpsN/etc/vmm-mmf.cfg) activate the MMF files when the

system boots. MMF files can also be activated from the MPS command shell. This is

useful for testing new applications and configurations. MMF files activated from a

command shell are not reactivated if the system is restarted.

See the Media Processing Server Series System Reference Manual for configuration

details and an explanation of MMF files and hash tables.

There are two methods for activating MMF files:

• For backward compatibility, the activation of MMF files during system

initialization is done by processing the vmm-mmf.cfg configuration file and

activating each listed MMF file in the specified manner (record, system-wide,

application-specific, etc). This activation method has several drawbacks.

When running with a secondary node backing up several non-homogeneous

nodes, VMM has to activate the same MMF files that were active on the

primary system. Keeping these files up to date on the secondary node is

difficult due to the fact that, the files can be located anywhere on the primary

system. Another drawback is that anytime a new MMF file is added, a

configuration file must be modified to ensure that on restart the MMF will be

loaded.

• The newer method is introduced in MPS software release 2.1. It requires all

MMF files to be in the $MEDIAFILEHOME directory (or one of its

subdirectories—see the diagram on the next page). Upon initialization, VMM

activates all MMF files in the $MEDIAFILEHOME/mpsN directory. Each

mpsN directory contains a system subdirectory, which stores the MMF files

to be activated system-wide. There is also a subdirectory for each application

for application-specific MMF files. Both the system and application

directories have two subdirectories named record and default. The

record subdirectory stores the MMF file into which data is recorded by

default. (This should be the only file in that subdirectory.) The default

subdirectory contains the default MMF (for playing) if one is needed. This

eliminates the need for the vmm-mmf.cfg configuration file and provides a

well-defined location from which a secondary node can periodically update

its MMF files. To ensure backward compatibility, VMM still attempts to

process the vmm-mmf.cfg file after activating any files in

$MEDIAFILEHOME. The processing of the vmm-mmf.cfg file is not

supported for systems with secondary nodes.

The Nx1 redundancy configuration does not support the use of vmm-mmf.cfg.
