secs

For an in-depth discussion of modifiers and interpretations, such as CSV and MAX,
used with the -I and -O parameters, see Section 4, Specifying File-Related Options
for DataLoader/MX.
-P=num-parts
directs DataLoader/MX to estimate the partition boundary keys for num-parts
number of partitions. For additional information, see Using the -P Parameter on
page 3-11.
-Q
runs DataLoader/MX in quiet mode. Normally, DataLoader/MX writes error and
informational messages to its stderr file. DataLoader/MX also writes to its
stdout file, which can be changed by OSS command-line output redirection, if the
stdout is different from stderr.
Specifying the -Q parameter directs DataLoader/MX not to write informational
messages to stderr. Error messages are still handled normally, and informational
messages are still written to stdout if it differs from stderr.
Use this parameter to reduce the number of messages on the screen when
running many DataLoader/MX processes simultaneously. When an error occurs,
try using an earlier informational message to understand the error. If you use -Q, it
is generally a good idea to redirect the stdout file to a disk file to capture all
messages. If you cannot diagnose a problem by using the error message, and you
