How to change the file generation
process [Enterprise Edition].
Prior to generating output files, the graphical interface
application will check for a file named installgen_win_custom.pm
or installgen_sol_custom.pm
located within the directory where it has been installed. If this file
is found, it will be copied to the destination directory and executed
along with the other Perl programs which are used to generate output
files.
There are two subroutines from the installgen_custom.pm
Perl module which are exported for use by the main Perl program.
The before_script_generation() subroutine runs after the
configuration parameters have been read from the installgen_conf.pm
file, but prior to the 1st output file being generated.
Adding code to this subroutine can affect globally used configuration
variables, which will be used throughout the file generation process.
The after_script_generation() subroutine runs after all
of the output files have been generated. This subroutine provides a
convenient location for DBAs to more fully customize any of the output
files which have already been generated. The recommended process to
follow is to look at the Perl source code which gets written to the
disk during the file generation process. Each output file is created
with a corresponding subroutine which is called from the appropriate
installgen_windows.pl, installgen_solaris.pl etc Perl program file.
Find and copy the subroutine which generates the file you want to change.
Past this code into the installgen_custom.pm file, and place a call
to this subroutine into the after_script_generation() subroutine. Modify
the subroutine as needed to make your custom changes to the output file.
If you allow the subroutine to use the default filename
($filename1, $filename2 etc), then your customized version of the output
file will replace the standard version of the file.
If you want to create a brand new output file, just provide
a filename which differs from any of the existing output files.
