Appendixes
This section contains additional reference information.
- The onpload database
The tables in the onpload database hold information that the onpload 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 High-Performance Loader (HPL). 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. - The HPL log-file and pop-up messages
This section provides explanatory notes and corrective actions for unnumbered messages that print in the High-Performance Loader (HPL) log file. The section also includes information specific to messages that are returned to standard output or appear in a pop-up dialog box (depending on the way you started onpload). - Custom drivers
If your operating system supports dynamic linking of libraries, you can use a custom driver to extend the functionality of the High-Performance Loader (HPL) to support different file types or access mechanisms. - Run load and unload jobs on a Windows computer
- Conversion and reversion scripts for HPL database migration
When you convert or revert to different versions of the database server, you can use conversion and reversion scripts to manually upgrade or revert your onpload database. You must use these scripts if you are required to upgrade between the same server versions.
