How to tell jvm in debug mode?
If we want to debug application servers, people told me to tell
the JVM in debug mode. something like: -XDebug

Hi,
Look at the (online) manual for your application server. You usually does it in different manners depending on the application server.

How to run labview in debug mode
Two questions:
1. how to run labview in debug mode
2. how to save default text values in labviewHi,
consider i have streaming bits of data as input who length varies each time. I need to select 11 bits at a time and apply (15,11) hamming coding for the inputs till the input is stopped.
I have designed the hamming encoding and decoding block. I need a methodology to select 11 bits at a time from the input and provide to the hamming encoder.
eg: if input is 1100 bits, output must be 1500 bits.
I have uploaded the encoder and the decoder part. Please suggest me the design to read the input and append the output.

How to start weblogic in debug mode from BEA WebLogic Eclipse plugin
I have a problem making weblogic work with eclipse3.1. I am using a BEA WebLogic plugin to handle weblogic (start/stop) from eclipse. However I want to debug my application and I am unable to figure out a way to start my weblogic in debug mode like we do in WSAD. I tried using some other plugins also but no luck. Please suggest me a plugin to handle this or any other way of debugging my application from eclipse. I am using weblogic 8.1.
Hi,
Dev Environment
weblogic eclipse plugin 2.0 beta
weblogic server 8.1
eclipse 3.1.1
Created a server that i would like to deploy my EJB so that i can put break points on my EJB in eclipse.
How do i do it?
I managed to deploy an ear (containing the ejb) directly to the weblogic installed folder and it deployed the ejb. But the breakpoint set in eclipse is not triggered. Of course in this case as weblogic server is running the .ear file deployed manually in the file system.
Any help is appreciated.

How to start server in debug mode by default
Hi,
Whenever the server starts it does not start in debug mode.
One has to manually start the "SDM" and "Server0" in the debug mode.
Is there a way I can make the server start in debug mode for the first time itself.
regards,
SaurabhHi Saurabh,
You can start the server in debug mode using config tool. Just open cofig tool (/usr/sap/<SYS ID>/JC<SYS NR>/j2ee/configtool/configtool.bat).
Click on the your instance. Then under the tab Servers Debug check Debuggable and also Enable Debug mode.
Restart the engine now.
However a word of caution: Starting the server in debug mode decreases the system performance. You should only start the dev server in debug mode.
Hope this helps.

TestStand how to check debug mode
I want to close the execution windows when done, and for this i've inserted a statement at the begining of the process model : RunState.Execution.TypeMask = RunState.Execution.TypeMask + 0x10. But i would like it to be executed only in debug mode.
How can i check TestStand debug mode ?
JMC
JMCeI've found my answer : i've a boolean "IsEditor", updated with an ActiveX action :
Object reference : RunState.Engine
Automation Server: TestStand API
Object class : Engine
Get Property : ApplicationIsEditor.
There are a lot of methods and properties accessible with ActiveX, but not so easy to find !

Sprint BlackBerry 8830 - how do we get in to debug mode...?
I have searched for two days everywhere and can not locate how we enter in to debug mode on the 8830.
I need access to the Rx Ec/lo and the SID#, currently I can only get signal strength in the home screen by pressing the ALT+NMLL (changes the graphical signal indicator to the numerical one, i.e. -80)
Please, I could really use some help with this so we can diagnose the repeaters on our corporate campus.
Thanks,
J
Solved!
Go to Solution.Well, to answer my own question, I have now found the answer.
Unfortunately, the 8830 and some of the other newer BlackBerrys do not make it easy to get this type of engineering information.
You must:
Have a login/password to https://www.blackberry.com/EngineeringScreens/ (updated 5/30/2008)
On the BlackBerry pres ALT+CAP+H and leave it on this screen.
Once logged in to the link on #1, you will be asked to enter your PIN#, Uptime and Zip code of where your device is.
You will then receive a unlock code that is specific to this information (if you exit out of this help screen on the blackberry, the uptime number will be different thus your code will be different.)
Then enter the unlock code on the BlackBerry, holding the ALT key for numbers, capitals are not necissary.
This will give you access to the Trace Mode Engineering App
Select "Radio Engineering" screen
Select "CDMA Engineering" screen
Select "Operational Info" (2nd line ec/io, 3rd line rss)
Scroll down to "Neighbor Set Details" and get 1st line Active Pilot, 2nd through 20th will give Neighbor sites with ec/io for each.
*This code will only work for 30 days, then you will need to get a new code in the same way.
I hope this helps everyone!

Hi all,
I would like to know how to run APPS in Debug Mode. I know the steps to enable debug mode at apps tier server level as below...
Log into the apps tier server as apps tier manager.
Edit $APACHE_TOP/Apache/conf/httpd.conf
LogLevel debug
Edit $APACHE_TOP/Jserv/etc/jserv.conf
ApJServLogLevel debug
Edit $APACHE_TOPJserv/etc/jserv.properties
log=true
wrapper.bin.parameters=-DAFLOG_ENABLED=TRUE
wrapper.bin.parameters=-DAFLOG_LEVEL=UNEXPECTED
wrapper.bin.parameters=-DAFLOG_MODULE=%
wrapper.bin.parameters=-DAFLOG_FILENAME=$APACHE_TOP/Apache/logs/aferror.log
Edit $APACHE_TOP/Jserv/etc/ssp_init.txt
DebugLevel=5
DebugSwitch=ON
Bounce the Apache Services for changes to take effect.
Now my question is, I want to know how to debug APPS in freont end. i.e.., I want to do it in APPS screens, if I do it at the apps tier server level, it'll be for all. But I want to do it for a single user (Just like running GUI tools such as VB,D2k in DEBUG mode).
Regards
-MaheshHi Sharon,
Thanx for the reply.
Actually, I don't want to debug using any profile values. As I pointed out, if we set the profile value debug mode is enabled for all the users using that particular module. But I want to do it for a single user, who wants to run in Debug Mode. Any more updates on this?
Regards

How can we process the CRM Order again for second time in debugging mode
Hi,
Can anybody please tell me how can we process the CRM ORDER for second time. that I want to process in debugging mode.
Thanks,
bsvHi bsv,
Are you trying to reprocess a BDOC for debugging purpose?
If the BDOC is not with a final status, you will be able to reprocess it using the reprocess button in the smw01 search result list.
And you may put /h on the popup when you click on the 'reprocess' button.
If it is allowed to make some changes in the CRM ORDER for testin purpose, it would be easier to perform debugging.
A more 'careless' way is to deactivate the outbound or inbound queue in transaction smqs or smqr, then in smq1 or smq2 to locate the interested queue, and click on button 'debug LUW'.

How to run the forms under debug Mode?
Hi,
I run my form under debug mode by introducing a break point on a trigger. But i am receive the following error how to solve this issue.
JVM aborting and followed by the following one.
FRM-92101: There was a failure in the forms server during startup.
This could happend due to invalid configuration.
Please look into the Web-server log files for details.and additional information from Java console.
proxyHost=null
proxyPort=0
connectMode=HTTP, native.
Forms Applet version is : 10.1.2.0
oracle.forms.net.ConnectionException: Forms session <5> aborted: unable to communicate with runtime process.
at oracle.forms.net.ConnectionException.createConnectionException(Unknown Source)
at oracle.forms.net.HTTPNStream.getResponse(Unknown Source)
at oracle.forms.net.HTTPNStream.doFlush(Unknown Source)
at oracle.forms.net.HTTPNStream.flush(Unknown Source)
at java.io.DataOutputStream.flush(Unknown Source)
at oracle.forms.net.StreamMessageWriter.run(Unknown Source)I am running on my standalone machine.
Where and what file i want to look into this to solve this issue.
Good help will be appreciated. Thank in advance.
kanishKanish,
Lets start with a few of the basics, shall we. What JVM are you using (Jinit or Sun JRE and the version)? Based on the error you posted, I can infer that you are using Forms 10.1.2.0? Are you running a custom configuration in the formsweb.cfg and default.env? This could be the cause if you have modified the CLASSPATH setting in the default.env excluding core .jar files.
Typically, the FRM-92101 error is caused by a Java error; either a .jar is not found or invalid or not compatible with JVM, etc.
Have you tried clearing your Java Cache to check for a corrupt .jar?
Hope this helps,
Craig B-)
