Form hangs while calling Report

Question

Hi, I am converting some Forms/reports from 6i to 10g.
The form I am testing is calling a report repeatedly using the following code:
rep_id := Find_Report_Object('FILE_RECORD_DESCRIPTION');
<<open_files>>
OPEN files;
<<get_next_file>>
FETCH files INTO file_name;
IF files%NOTFOUND
     THEN
     CLOSE files;
     RETURN;
END IF;
:FILE_RECORD_DESC_STATUS := 'Doing file' || file_name;
SYNCHRONIZE;
IF :TYPE = 'PDF'
     THEN
     SET_REPORT_OBJECT_PROPERTY (rep_id,REPORT_DESNAME,'C:\DOC\PDF\' || file_name || '.pdf');
     SET_REPORT_OBJECT_PROPERTY (rep_id,REPORT_DESFORMAT,'PDF');
SET_REPORT_OBJECT_PROPERTY (rep_id,REPORT_OTHER, 'P05_FILES="' || file_name || '"');
END IF;
IF :TYPE = 'HTML'
     THEN
     SET_REPORT_OBJECT_PROPERTY (rep_id,REPORT_DESNAME,'C:\DOC\' || file_name || '.htm');
     SET_REPORT_OBJECT_PROPERTY (rep_id,REPORT_DESFORMAT,'HTML');
SET_REPORT_OBJECT_PROPERTY (rep_id,REPORT_OTHER, 'P05_FILES="' || file_name || '"');
END IF;
report := Run_Report_Object(rep_id);
GOTO get_next_file;
When REPORT_DESFORMAT is set to ‘HTML’, everything works well. Around 40 .htm documents are created on C:\DOC. But when REPORT_DESFORMAT is set to ‘PDF’ the form hang after creating 10 or 11 .pdf documents!!!
Any idea what I am doing wrong? Do I have to free up some sort of buffer/memory/other things when creating .pdf document?

Answer 1

I tried different things and it seams that the amount of data (i.e the size of the .pdf) determine how many times the report can be called before the form hangs. Form did hang after only 2 call for big report (around 20 pages each) but hangs after several calls for smaller ones???
