Much better is

my $config = GlobalConfig->new;

# compile-time error
if ( $config->mis_dbtype = 'db2' ) { ... }

# This works
if ( $config->mis_dbtype == 'db2' ) { ... }

Get rid of the ampersands. Also, why haven't you wrapped the contents of this if-block in a subroutine?

sub do_logging {
    my ($rescode, $browsecode, $summarycode) = @_;

    ResCode( $rescode );
    BrowseCode( $browsecode );
    NewLine();
    SummaryCode( $summarycode );
}

if ( readFileContents( $lofFile, $ContentsLoadMsg ) == $FALSE ) {
    do_logging( 'E_LOADMSG_ERROR', 'Could not open "$logFile"', 'E_MIS
+LOAD_ERROR' );
    return $FALSE;
}
