"JVM heartbeat .. dead" in trace file - how to diagnose it?

One of our customers reported, that Java applet hosted on our website (running in Java Plug-In 1.6.0 update 23, Mozilla Firefox 3.6.13) seems to terminate in the same situation each time. This is a signed applet, which is about to estabilish a HTTPS connection. The last line in trace file is:
JVM heartbeat .. dead, send ts: 2017852585, now ts: 2027867626, dT 10015041
The symptoms of terminating applet are:
- black, dead area in browser where the applet was previously present
- "Java Console" window suddenly disappearing
How can we debug this situation? How can we find out if it really is a JVM crash? Where are such crashes logged when they occur? Should there be a hs_err** file on user's desktop?
Thanks for any help.

There was a bug logged a while ago with a similar error which seems to point to the JVM running out of memory. There is a workaround posted in the bug report. Maybe that can help you?

How to create the trace file using run_report_object at runtime

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.

How to find out the Trace file

Hi Dba's
I need to find out the trace file with the Request id. how can i find out it?

There are many ways to create a trace file in the apps. Pl provide details on how you enabled trace, as that will determine where the trace file is created.Concurrent requests trace files are always created under USER_DUMP_DEST directory.

How to identify which trace file is your backup controlfile trace in udump

I have a 10.2.0.3 database on unix.
I want to setup a job to run a script every night to backup the controlfile as text format.
such as "alter database backup controlfile to trace".
How my script can identify which trace file is the one just created for backup controlfile and copy the file to a backup disk?
Thanks a lot!

I thought it's
alter database backup controlfile to trace as 'absolute path of any file where you want the control file in clear text format ';
for ex. in Windows..
alter database backup controlfile to trace as *'c:\temp\create_ORCL_control.sql'*;
This way you will know where your job is going to backup controlfile to trace

How to read a trace file?

Can someone point me to a good resource where I can learn how to read a trace file? I have read somewhere that TKPROF can leave some things unattended. Worse, it reports things incorrectly.

I usually recommend use Trace Analyzer (TRCA), Note:224270.1
It includes all the details found on TKPROF, plus additional information normally requested and used for a transaction performance analysis. Generated report is more readable and extensive than text format used on prior version of this tool and on current TKPROF.

How to find trace file error in form

hai all,
i have big problem in my form in apps i open the form one error is ocuured,
i got the trace file and check the error,
PARSE ERROR #82:len=2903 dep=0 uid=173 oct=3 lid=173 tim=4265689973879 err=904 this is the trace file error meassage,
how to find this error in form and also this is occured one select statement,how to find this select statement where can be used in form,
i have one button ,when ever i press the button this error is ocuured,i check this button pl/sql procedure code but in this code not using that sql statement,
if any one know to find the sql statement through trace file.
plz give the replay as soon as possible.
thank's

The newest SQL Developer can converts the trace to readable format too, I'm not shure if you see the sql statement related to the error then.
It seems you get ORA-00904 which says you use an invalid coumn in a dml statement.
Normally such error should pop up in message - do you overwrite the message handling or use exception handling in you form which block this message?
Easiest way to find this is to compile the form against the target database.
If this does not give an error, you should check, if you use dynamic sql statements which are wrong.
If you call database routines from your form, than this could be the errro cause too.

How to proceed further once the explain plan and trace files are generated?

Hi Friends,
I need to improve the performance of on of the views that i am working on.
As suggested in the thread - http://forums.oracle.com/forums/thread.jspa?threadID=863295&tstart=0 , i gave generated the explain plan and the trace file.
From the explain plan, we can see the expensive operations for the query.
Can any one please tell, how to proceed further from here on i.e. how to make this expensive operations less expensive?
For ex: FULL TABLE SCAN might be an expensive operation when the table has indexes.In such cases, how can we avoid such operations to make query faster?

Hi Veena,
An earlier post by you regarding P45 is as below
Starter report P45(3) / P46 efiling for UK
from my understanding though i have not worked on GB Payroll you have said that you deleted IT 65 details of leaver,however there must be clusters generated in system from where the earlier data needs to be deleted and may be that is why you are facing the issue.
In Indian payroll when we execute text file for efiling of tax after challan mapping all the data compiles and sits in PCL cluster and therefore we are unable to generate form 16 with proper output,here we delete the clusters and rerun again the mappings and then check form 16.
Hope this might help you,Experts have suggested you earlier also,they may correct me for this.

How to change trace file location in Oracle Fusion Middleware

Hi all,
I would like to know how to change the location of the trace file in Oracle Fusion Middleware - Report Server 11g ?
I notice there is logging.xml file in $ORACLE_HOME/config/ReportServerComponenent/logging.xml. In the xml file, it did specify the location of the diagnostic file and other log files.
Is it the correct way to reconfigure the location of the log file? I havent try it though. :D
Thanks.

Hi Fleix,
For additional instructions for Release 11i, see Note.167635.1 and Note.150168.1.
For additional instructions for Release 11.0.3 and 10.7, see Note.148982.1 and Note.135715.1.
a. Append the following to the end of the URL used to login to the Oracle Applications:
?play=&record=collect&log=/tmp/oracle.FRD.log
** Note: The self service login URL will not work for creating FRD trace files. You may need to talk to your technical team to get the URL that accesses the forms server directly.
b. If the URL to logon to 11i applications is:
http://machine:9603/dev60cgi/f60cgi
Then the following label needs to be included:
?play=&record=collect&log=/tmp/'file_name'.frd
For example to create frd for above url log in to application as
http://machine:9603/dev60cgi/f60cgi?play=&record=collect&log=/tmp/4764802.992.frd
c. Now log into the application and go directly to the form with the problem and perform the actions which generate the error.
Once the error has been generated and cleared, immediately log out of the application so no additional diagnostics are captured.
d. The diagnostics will be written to the file specifed after "log=". In the example, this would be /tmp/4764802.992.frd
e. After reproducing the issue, log on the server side of the instance and go to the directory to /tmp (cd tmp)
f. Retrieve the frd file: /tmp/4764802.992.frd
This file contains all the details about built-in programs, triggers, procedures in a FORM
Thanks,
Anchorage :)
