This field indicates the number of committed transactions
    after which a checkpoint will occur. By default, if you have
    fast commit processing enabled, a process checkpoints when the
    AIJ block size limit is reached or the time interval limit is
    exceeded, whichever occurs first. You can specify the number of
    transactions as the checkpoint trigger by defining the RDM$BIND_
    CKPT_TRANS_INTERVAL logical name.
