Search something smaller.

Like the onconifg.std that came with the 11.50 engine you have installed.
( they group items and also give definitions and other information in the
onconifg file itself )

You will find the proper spelling there I believe its something like one of
these below.:

more onconifg.std

###################################################################
# Parallel Database Query (PDQ) Configuration Parameters
###################################################################
# MAX_PDQPRIORITY - The maximum amount of resources, as a

# DS_MAX_QUERIES - The maximum number of concurrent decision

# DS_TOTAL_MEMORY - The maximum amount, in KB, of decision
# support query memory
# DS_MAX_SCANS - The maximum number of concurrent decision
# support scans
# DS_NONPDQ_QUERY_MEM - The amount of non-PDQ query memory, in KB.
# Acceptable values are 128 to 25% of
# DS_TOTAL_MEMORY.
# DATASKIP - Specifies whether to skip dbspaces when

# - ALL Skip all unavailable fragments
# - ON <dbspace1> <dbspace2>... Skip listed
# dbspaces
# - OFF Do not skip dbspaces (default)
###################################################################

MAX_PDQPRIORITY 100
DS_MAX_QUERIES
DS_TOTAL_MEMORY
DS_MAX_SCANS 1048576
DS_NONPDQ_QUERY_MEM 128
DATASKIP

I hope the colors come out on your screen.

I searched both the following configuration parameters, and did not get
any result in IDS11.50 info center,

DS_NONPDQ_QUERYMEM

DS_NON_PDQ_QUERY_MEM

Any idea?

Thanks,
Frank
