Considerations—DataLoader/MP Process
file with a record size of 20. When DataLoader/MP successfully commits a
transaction, it writes the last number of records read from input to this file. If an
error occurs, this file contains the record number that was committed
successfully. When DataLoader/MP is restarted with this restart file, the
previously processed records (as recorded in the restart file) are skipped.
PURGE
specifies that DataLoader/MP purges the file containing restart information on
normal termination. After any abnormal termination, the file will still exist.
KEEP
specifies that DataLoader/MP never purges the file. You must purge it after
determining that the load application was successful.
KEEP is the default.
If the output requires a transaction ID and -T= was not specified, DataLoader/MP
terminates with an error.
-X=exitlist
specifies optional user exits to call and in what order to call them. For more
information, see User Exits on page 5-1.
Considerations—DataLoader/MP Process
In addition to the preceding DataLoader/MP parameters, user exits can have optional
or required parameters. By convention, all DataLoader/MP parameters defined by HP
begin with a dash, and parameters for user-defined exits do not begin with a dash. For
a brief list of all parameters supplied by HP, run DataLoader/MP with the -H parameter.
Use parenthesis only to enclose modifiers after file names. Any other qualifying
information is enclosed in angle brackets, even within file modifiers, as follows:
DATALOAD -t=100<restartfile=filename>
DATALOAD -i=file1(recform=fb<recsize=100>)
The restart file name is enclosed in angle brackets because “restartfile=filename” is not
a file modifier. The entire recform=fb<recsize=100> clause is enclosed in parentheses
because it is a file modifier. <recsize=100> is enclosed in angle brackets because it is
qualifying information specifying the length of the fixed length records.
When specifying a number, if it is used in the % file modifier it can have a decimal
point. A number used in parameters cannot have a decimal point.
Specifying File Names
Except when specifying the TMF restart file with the -T parameter, use the following
format to specify a file for DataLoader/MP:
