How to create the trace file using run_report_object at runtime

Question

Dear All
using :
Oracel Application Server 10g
Oracle Database 11g
Windows XP/sp3
I'm using run_report_object to call a report inside the form. THis report is running OK from reports builder, however it's too slow when run from Application server.
How Can I create a trace file (at runtime) that contains the time spent in sql and formating the layout of the report ??
Here is My code :
repid := find_report_object('report5');
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_FILENAME,'INVOICE.REP');
v_url :='paramform=no';
v_url := v_url||' FROM_NO=' || :PRINT_BLOCK.FROM_NO ;
v_url := v_url ||' TO_NO=' || :PRINT_BLOCK.TO_NO ||' FROM_DATE=' || v_from_date ||' TO_DATE='|| v_to_date ||' NO_DATE=' ;
v_url := v_url ||:PRINT_BLOCK.NO_DATE||' IDENT=' ||:PRINT_BLOCK.IDENT_NO||' REPORT_HEADING='''||V_REPORT_HEADING||'''' ;
v_url := v_url||' COMPANY_NO='||:global.company_no;
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_OTHER,v_url);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_SERVER,:GLOBAL.INV_REPORT_SERVER_NAME);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_DESFORMAT,'pdf');
v_rep := RUN_REPORT_OBJECT(repid);
IF rep_status = 'FINISHED' THEN
V1:='/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1);
WEB.SHOW_DOCUMENT('/reports/rwservlet/getjobid'||substr(v_rep,instr(v_rep,'_',-1)+1)||'?server='||REPORT_SERVER_NAME,'_blank');
END IF;
Thanks a lot

Slow running reports often are not the result of a flawed report, but rather a flawed configuration. For example:
1. If you call your reports (from Forms) via the default or inProcess Reports Server, often because startup time is slow, it will appear that it took too long for the report to be delievered. Using a stand-alone Rep Server is the preferred way to do this.
2. If your Forms application makes numerous calls to RRO (RUN_REPORT_OBJECT), this can tend to result in what might appear as a memory leak (although it is not). The result is delayed processing because of the excessive memory use. This problem has been overcome in Forms/Reports 11 by the use of JVM pooling. However in v10 enabling "6i compatibility" mode is the way to overcome the issue. See Note 266073.1
3. If the report runs fine from the Builder and it is connecting to the same db as when you run it from App Server, the issue is unlikely a db problem. However, if you want to look anyway, enable sqlnet tracing.
4. To enable Reports tracing and investigate other tuning options, refer to the Reports 10 documentation:
http://docs.oracle.com/cd/B14099_11/bi.1012/b14048/pbr_tune.htm
Almost forgot to mentioned this one....
If you are using a v11 db with App Server 10, you will probably want to consider reviewing Note 1099035.1 as it discusses an issue related to performance with such a configuration.
