The dsi_large_xact_size parameter setting should be larger than the number of statements modified by an ordinary transaction and larger than the number given by the formula below. If the number below is smaller than the number of statements in an ordinary transaction, the sqt_max_cache_size parameter should be increased. The formula is:
dsi_large_xact_size = ( (sqt_max_cache_size/ dsi_num_large_xact_threads) - O) / S
