utility uses. This section describes the tables in the onpload database that you create or modify with
ipload
.
High-Performance Loader configuration file
The default
$INFORMIXDIR/etc/plconfig.std
file on UNIX™ or
%\INFORMIXDIR%\etc\plconfig.std
on Windows™ is the
high-performance loader configuration file
.
Picture strings
The HPL uses two types of picture strings: COBOL picture strings and other picture strings.
Match condition operators and characters
This section describes the operators that are available when you match text and it provides an example of each operator.
Custom-conversion functions
Custom-conversion functions allow you to add additional data conversion capability to the . This feature lets
onpload
call a custom-conversion function during the data-conversion process.
The onstat -j option
The
-j
option of the
onstat
utility provides special information about the status of an
onpload
job. The
-j
option provides an interactive mode that is analogous to
onstat -i
.
