4.8.5 Setting the SANITYSCAN, BLOCKTIME, BBLQUERY, and DBBLWAIT Parameters
If a system is running on slower processors (for example, due to
heavy usage), you can increase the timing parameters:
SANITYCAN, BLOCKTIME, and individual
transaction timeouts. If networking is slow, you can increase the
value of the BLOCKTIME, BBLQUERY, and
DBBLWAIT parameters.
