Java Exceptions in Server Trace file

Is it possible to tell the Server (817)
not to write the Java exceptions into the trace file ?
thx in advance

Java -Djava.rmi.server.codebase=file:///.....

Cross posted in the hope that someone using it knows how....
I am using the following command:
java -Djava.rmi.server.codebase=file:///home/ben/fyp/build/ -Djava.security.policy=security.policy -cp ./lib/bcprov-jdk15-130.jar:./props:./build com.bensmyth.fyp.example.IssuerServer
Can I specify -Djava.rmi.server.codebase=file:///home/ben/fyp/build/ without giving the whole path? Can I say ./build?

I've come back to this issue again (since I am moving code around to different systems again). Using linux I can use -Djava.rmi.server.codebase=file://$PWD/build/
Presumably there is a similar command in WIndows.

Shared server trace file

Hi All,
Our production db is 10.2.0.3 with 2 nodes RAC in MS 2003 window servers. I am wondering what kind of information that Oracle capture in the shared server trace file (file name looks like instance_s001_3333.trc) . When I open some of these files I always see one query always there along with the messages like:
WAIT #8: nam='gc cr block 2-way' ela= 1222 p1=65 p2=49677 p3=1 obj#=69689 tim=4137263779
WAIT #8: nam='gc cr block 2-way' ela= 593 p1=65 p2=50863 p3=1 obj#=69689 tim=4137265531
WAIT #8: nam='gc cr block 2-way' ela= 592 p1=65 p2=50879 p3=1 obj#=69689 tim=4137266700
Should we need to tune this query to make it disappear in the shared server trace files? What are the conditions to trigger Oracle put this query into trace file?
Thank you very much in advance for your support!
Shirley

These trace files are very likely generated by some trace statements originating from client programs connected to shared server processes such as client application processes, SQL*Plus, SQL Developer, OEM, TOAD, etc.
Is your client application instrumented ?
Do some people analyze performance problems on the database side ?
The triggering statements may be some ALTER SESSION statements or package calls like DBMS_MONITOR in 10g or other
(see examples in http://www.oracle.com/technology/oramag/oracle/04-jan/o14tech_perf.html).
You should also check that instances are not configured with instance level tracing:
show parameter sql_traceYou can also check current database sessions sql tracing status with:
select sid, serial, program, sql_trace from v$session where username is not null;

Java.rmi.server.codebase=file:(?????); at client side: classnotfounexceptio

I'm trying to run an RMI application (under Windows XP, one machine for client and server) like this:
at server side:
java -Djava.rmi.server.codebase=file://\..\..\..\j\ -Djava.security.policy=file:.\polityka.txt sss

results in:

when I'm listing directory (at client side) got with System.getProperty("java.rmi.server.codebase") i get this

Unable to generate SQL trace file in shared mode ??

Hello,
I have a 10.2.0.1.0 database on Win2003 server 64 bits, with several instances.
On instances in dedicated mode, I can create trace files by using dbms_system.set_sql_trace_in_session, but on instances in shared mode nothing happens : no file is created in the udump directory.
This doesn't make any sense to me o_O
The shared parameters are the following :
dispatchers=(protocol=TCP)
shared_servers=1
I've checked all the necessary parameters to create a trace file (user_dump_dest, timed_statistics, max_dump_file_size...) and everything is fine.
I really don't understand why I can't create trace files when the instance is in shared mdoe...
Can anyone help about this weird issue ?
thank you !
regards,
Antoine

Remember also that in Shared Server mode the trace information is not written to a single file but is written to the Shared Server trace file. Before Oracle 10g there was no way to pull all the trace information for a single user session together out of the trace files. There is a tool for doing so with 10g.

Deleting default trace file in java

Hello all,
Whats the best way to automatically delete default trace file in java instance? I want to delete these files lets say every week or 2 wkkds,Is there any type of configuration that can be done through NWA or OS...? or do i have to write some scripts? Please advice.

Perfect.
When set to 10, 0 -->9 are cyclic files. Regarding archiving, yes this is possible. Apart from defaulttrace files you can also archive other java log files (system, network,security etc). The configuration procedure is explained :-
http://help.sap.com/saphelp_nw04/helpdata/en/48/2edfd5bd3e0d4a81b90325fe195a70/frameset.htm
Once the 10th trace file(i.e.defaultrace9) is full, all the trace files (from defaulttrace0-defaultrace9) are zipped to a single file. The file compression ratio is extremely good.
Unfortunately there is no automated mechanism to clear off the archived files. This needs manual intervention(regular cleanup, script etc).
The archived log files may also be viewed for analysis from NWA.
While estimating the size for each defaulttrace consider three factors i) System load ii) Number of defaulttrace files.
iii) Retention days(without archiving)
Ex: System load as observed :
Say the trace file size is 10MB and 6 trace files get written in 4 hours of peak time and 1 trace files is written for 4 hours during non-peak time .Assuming 8 hours of peak business hours and rest all non-working hours.
No of files generated is 62 + 14 = 16 files of 10 MB each are generated per week day
If the defaulttrace file count is set to 16, you can retain one days' logs . Say you wish to retain the same with less number of files (i.e. 8) you would have to increase the file size to 20 MB. Also will have to look at file system space availability.
CAUTION: For a file system occupancy estimate, you will have to also consider as to how many Server nodes are
configured as each node has its own log area !
For this you need to observe the pattern as to how many files are being written then estimate the size and count
cheers !

SQL Developer generates strange trace files on server

Hello out there,
I observed the generation of some strange trace files on the database server (Oracle 11.0.2.0.2 64bit on Win 2008R2).
Whenever I start SQL Developer (3.2.20.09.87 64bit with JDK 1.7.0_17 64bit on Win7 64bit) for each connection I defined one trace file like this is generated:

This also occurred with JDK 1.6 so I don't think it's a Java issue.
Besides the generation of the trace files there seem to be no other problems.
Any ideas?

Hi,
I think Srini is probably correct. The noted bug applies to 11.2.0.1 and up, is fixed in 12c, and included in an 11.2.0.3 patch. However the version of SQL Developer also affects the creation of trace files on product startup (prior to any user initiated db connect attempts).
For example,
A. SQL Developer 3.1.07.42 - no such trace files created.
B. SQL Developer 3.2.20.09.87 - such trace files created for 11.2.0.1 connections, but not 10g XE or 12c connections.
So I presume an OCIServerAttach call got added in 3.2.2, not sure in support of which feature, but the bug will only impact users of 11.2.0.1, 11.2.0.2, and unpatched 11.2.0.3 DB releases.

7.1: Insert-Exception only appears in trace-file ?

Hello,
this is a question relating to SAP Mobile 7.1, we are developing an application for Handhelds.
I have the following situation:
- In my Services Component I define the DO "Equip" with an unique index on attribute "nr".
- I create a new Equip and set its attribute "nr" to an already existing value in the DB.
- I perform a commit.
=> I only can see in the application trace-file that an SQLException occoured ("Error inserting row --> java.sql.SQLException: Duplicate unique index") but the exception isn't propagated to my application so my application has no chance to notice that something went wrong. Even worse: The complete record is lost !
What do I have to do to receive this exception so I am able to notify the user that the record contains invalid data before it is lost ?
Thanks a lot,
Björn

we have another situation in which the framework catches an exception and just drops it silently, and drops the data as well.
In another support message we noted the following behaviour:
- form field length: 20
- db field length: 10
- insert succeeded (in an older Patch Level)
- but an error happened during the sync (SAP message 510534)
we just received a fix (SP05 PL04) and this is what happens now:
- insert throws an exception (text see below)
- the framework catches the exception
- and drops it silently
- the application does not see that anything went wrong
ok, I understand that I just should fix the length in the form field. Easy.
But the whole exception handling in the persistence layer should be reviewed.
Cheers, Andre

Try to set weblogic.jar with in pre-classpath in setdomainEnv.sh file and restart the server
You will find the weblogic.jar with in %WLS_Home% / server / lib

Java Exception after File Upload while retreiving using Filepath

Hello everyone,
I am performing the following steps:-
1) I am uploading a file from my local File system (D:/ a.XML) using FileUpload UI Element in Web Dynpro.
2) In the OnActionMethod of the View, I am trying to get the content of the file using the Filepath (D:/ a.XML).
But I am getting a Java Exception "No Such File or Directory" after deploying the archive and run on to the remote server.
The Exception is not a Web Dynpro Runtime Exception. But I am able to catch it in the try, catch block of the Java code.
Do I need the file to be present in the server as well. What is the Solution? Please advise me about, where is the content of the uploaded XML file stored and how can it be retrieved.
How can I retrieve the content of the file using a valid file path, because my method which will open the uploaded file requires argument as a filepath. Please suggest about this problem. I would be very thankful for your help.
Kind Regards,
Phani.

Timestamp in Java log and trace files.

Hi SAP'ies
Running PI 7.11 on AIX 6.3 we face an issue with the content of log and trace files from Java.
Eg.
The file DefaultTrace_00.0.trc is timestamped 18-05-10 11:16:15. (The same time as the time of the OS/AIX)
Looking inside the file the last statement is timestamped 2010 05 18 09:16:15.
How can we ensure that the content of these Java files are timestamped with OS time?
Looking into ABAP files like dev_w0 the timestamp of the file and the content are equal.
Best regards,
Teddy Løv Andersen

Hello All
Best way to convert the default trace time is , visit the site
http://www.csgnetwork.com/epochtime.html
here enter , for example if you have the following in default trace
#1.#00265510DE7300120000000F000022030004C77AD7309DF5#1345230317066#com.sap.portal.fpn.rdl
1345230317066 is time stamp , enter this in the above site to get the time

Java Plug-In Trace File names

According to this URL, http://java.sun.com/javase/6/docs/technotes/guides/deployment/deployment-guide/tracing_logging.html , the plug-in trace file should be named as indicated:
The names of the trace and log files are
plugin<modified version number>.trace
plugin<modified version number>.log
where the <modified version number> includes the major, minor and patch version numbers; e.g., plugin142_06.trace or plugin150.log
But this is not what we're seeing. We see the trace and log files, but here are their names:
plugin28434.trace
plugin28435.log
We are using JRE 1.6.10 on Windows.
We also have the following questions:
1. Is there any way to set the maximum file size for a trace file?
2. Is there a way to set how many backups of the trace file are used?
3. Is there a way to set the rolling behavior of the trace files? Right now, old trace files are re-written completely at random.

Any one has found any solutions ?
