A new, cluster-wide database of channel counters is created
    with the PMDF COUNTERS/CRDB command. The new database will have
    all counters zeroed except for the counts of stored messages,
    recipients, and message volumes for each channel. Those counts
    will be determined by the entries in the PMDF queue cache
    database. In addition, if an in-memory section for association
    and channel counters on this node does not already exist, it will
    be created as well.

    Once an on-disk database exists, its values may be updated
    from the node-specific, in-memory sections by using the PMDF
    COUNTERS/SYNCRONIZE command.

    Note that since some initial database values will be set based on
    entries in the PMDF queue cache database, you may want to issue a

    $ PMDF CACHE/SYNCHRONIZE

    command before issuing the PMDF COUNTERS/CRDB command, to ensure
    that the queue cache database values are themselves current.
