Remote Debugging in Jdev EA1.

Hey guys, what happen to remote debugging in Jdev EA1?
Thanks,
Tony

The remote debugging was moved to tools/project properties select run/Debug and then edit.
Thanks,

Cannot remote debug from JDev 10.1.3 on AS 10.1.2 running hotspot

Hi,
I've set up an embedded OC4J instance in an application server as described in the help topic, "Remote Debugging in OC4J" (with a few changes, such as the fact that I added startup options using the OC4J instance Admin page of EM, rather than at the command line (since the instance is embedded in a full AS). I followed the directions specifically for HotSpot, because that's the JVM the instance was set up to use, and I can't change it (I know OJVM enables lots more features, but that's the situation I'm in).
I've also configured my project for remote debugging, ensuring the host name and port matches, and trying both "Attach to JDPA" and "Attach to OJVM" (these being the only two options, except for starting a listener, which I don't think will help with a web application).
When I try to debug, though, I get:
Debugger unable to connect to remote process.
Should I be doing something differently?
Thanks much,
Avrom

I had the delete key quit working after accidentally pressing a key sequent that included the delete key. I don't know what keys were involved, but the delete key from that point on did nothing.
I am running JDeveloper 10.1.3.0.4 on Window XP.
To resolve the problem, I set the keyboard Accelerators back to 'Default' in JDeveloper.
I selected... Tools->Preferences->Accelerators
then click on 'Load preset' then I chose 'Default'
You may need to select something other than default for your platform, but that did the trick for me.

JSP Remote debugging from Jdev to WL 7.0

          I am trying to remote debug my JSP deployed on WL from Jdeveloper 903.
          I have included the parameters to make WL start in a debug mode.
          I have also included ojsp.jar, servlet.jar and ojc.jar in WL classpath.
          So I can start WL in debug mode, I can launch the url to get access to my JSP,
          a break point is included in the code but it doesn't stop at the break point.
          I am using JPDA.
          Do I have to modify something else to be able to remote debug my JSP?
          PS: remote debugging my EJB works fine.
          Thanks for your help


          Is there any possibility to change the JSP engine in Weblogic server and customize
          the new JSP
          with additional parameters, so that IDE's can debug JSP code itself?

Could not configure Remote Debugging (JDev - AS 10g)

I'm trying to make work remote debugging from JDeveloper 10.1.2 on Oracle AS 10g, but I'm stuck. I tried to do every step from JDeveloper help:
1. Create remote debugging process.
- Done (I hope)
2. In the <jdev_install>/lib directory, copy xmlparserv2.jar to <OC4J_HOME>/lib. In the <jdev_install>/jdev/lib directory, copy ojc.jar and jdev-rt.jar to <OC4J_HOME>/home/lib
- If ORACLE_HOME is C:\Oracle\oracleas, then where is OC4J_HOME ? c:\Oracle\oracleas\j2ee\home ? But it means to create another 'home' directory, right ? But I have already created one OC4J instance called FirstOC4J, where our applications are deployed and it is located in c:\Oracle\oracleas\j2ee\FirstOC4J. Now what ? Which one?
3. Edit global-web-application.xml, but it is both in c:\Oracle\oracleas\j2ee\FirstOC4J\config and in c:\Oracle\oracleas\j2ee\home\config directory. Which one ?
4.Start OC4J in debug mode from a command line
- Why from command line? I always managed our FirstOC4J from Enterprise manager. I tried to put there the parameters from the command
java -ojvm -XXdebug,port4000,detached,quiet -jar oc4j.jar
but parameters inserted into OC4J Options or Java Options were rejected (OC4J wouldn't start). A little succes was running OC4J like this
how to set up for remote debugging?
But it required our FirstOC4J stopped and it meant our application won't run.
Please , could somebody make some step-by-step instructions for begginners or at least comment some above points ? Thanks.

How to remote debug JSPs on Tomcat 5.0 from JDev 10.1.2

I can remote debug Java applications and servlets. But I can not make it stop within any JSP pages while doing remote debug. I have no problem if I debug locally within the built-in OC4J server.
I set my project properties with remote debugging -> Attaching to JPDA. I start my tomcat using catalina jpda start after setting environment variables JPDA_ADDRESS=8000 and JPDA_TRANSPORT=dt_socket.
Please help,
TIA

Ashraf, thanks for sharing your experience. I would like to comment on your precedure.
Jdeveloper 10.1.2
Tomcat 4.1.31 ( version 5.x.x won't work as it needs jdk 1.5 at least, and jdev is configured to run with 1.4 )I was able to use Jdeveloper 9.0.5 to debug a servlet running in Tomcat 5.5.9 with jdk 1.5.0. I would belive there is no fundamental obstacle for Jdeveloper 10.1.2 to debug Tomcat 5.x.x, thanks to the nature of JPDA.
a- backup $TOMCAT$\bin\catalina.bat.
b- edit $TOMCAT$\bin\catalina.bat to include the following:
set JAVA_OPTS=%JAVA_OPTS% -Xdebug -Xnoagent -Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000Another way is to set your environment variable JAVA_OPTS. There is then no need to modify catalina.bat.

Remote Debugging (Jdev 10.1.3 to AS 10.1.3)

Hi,
I have been trying to do a remote debugging by connecting Jdeveloper (version 10.1.3 production) to AS 10.1.3 mid-tier but the OC4J instance seems to be crashing the moment the jdeveloper makes the connection. However, before the crash, jdeveloper takes about 5minutes to connect to the server.
The OC4J is managed by opmn and not a standalone process. I am not sure if this makes any difference. Here are the changes that I made in the 10.1.3 server:
*) Modified opmn.xml to add the below:
<data id="java-options" value="-server -verbose:gc -Xmx512M -Xms128M -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=43503 -XX:MaxPermSize=128M -XX:NewRatio=2 -XX:+PrintGCTimeStamps -XX:+UseTLAB -XX:ParallelGCThreads=2 -Djava.security.policy=$ORACLE_HOME/j2ee/oacore/config/java2.policy -Djava.awt.headless=true -Dhttp.webdir.enable=false"/>
(also tried removing "-server" option)
*) Modified orion-web.xml to add the below:
<init-param>
<param-name>debug_mode</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>developer_mode</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>encode_to_java</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>emit_debuginfo</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>jspjavacompiler</param-name>
<param-value>oracle.jdevimpl.jsp.JspOjcCompiler</param-value>
</init-param>
*) Modified global-web-application.xml to add the below:
<orion-web-app
jsp-cache-directory="./persistence"
servlet-webdir="/servlet"
development="true" >
I see the below message in the jdeveloper debug window when the OC4J instance crashes:
Debuggee process virtual machine is Java HotSpot(TM) Server VM.
Debuggee process is application server OC4J.
To test JSPs or servlets, you must start a browser.
Debugger disconnected from remote process.
I do not see any error in application.log file.
By setting up the remote debugging, I am hoping for a better portlet development experience.
Any help is appreciated.
Thanks,
Pandian.

The doc is kind of vague, but here's the root reference:
http://download.oracle.com/docs/cd/B25221_04/core.1013/b15976/opmnxml.htm#sthref144
There's a FAQ document that prescribes how the "restart" algorithm works, see 1.3:
http://www.oracle.com/technology/products/ias/ohs/htdocs/opmn-1013-faq.pdf
So to tweak this behaviour, you specify a speciifc <ping> element inside of the opmn.xml for the managed process you are using -- and set the timeout, interval, retry attributes to some combination that gives you a longer pause time.

            </process-type>
         </ias-component>Now I did just see something that is either a bug, or a doc error. In the doc, it shows the attributes of the <ping> tag to be: timeout, retry, interval. However when you configure opmn.xml with these, it report an error.
Looking at the $ORACLE_HOME/opmn/conf/opmn.xsd file, it shows that only attributes are timeout and interval. You can't add a retry attribute. I'm not sure if this is a doc bug or an error in the XSD file.
Anyways, using the timeout parameter, for your DEBUGGING phase (not production!) you should be able to bump that up to a higher value to allow OPMN to wait longer for a response from OC4J before it nukes it.

Remote Debugging Servlet on JDev 10g

How do we setup JDeveloper 10g for Remote Debugging for Servlet? We have Oracle Application Server 10g with OC4J containier. I know we need to start OC4J in debug mode, but don't know hot to do it. Jdeveloper and OracleAS is new to me.
Thanks in Advance!

Remote Debugging w/9iAS not working !

I tried posting this in the app server area but apparently, it's too difficult for anyone to answer. No replies.
We need to debug a deployed jsp that uses java beans.
The jsp/java beans app is in jdevleoper 9.0.3.1 (windows 2000).
I have deployed the application to Oracle 9ias java edition (9.0.3) on Red Hat Linux.
I know how to modify the project settings in jdeveloper for remote debugging.
when I start debug mode in jdeveloper I am prompted for the host name and port number for the remote debug session. What port do I use ?
Do I need to do something to start 9ias at a certain port ? If so, how do I do this ?
I have seen conflicting information on this that mainly refers to a standalone oc4j, not the oc4j in 9ias.

Hi,
We have gotten many requests for collateral that details these steps. We are currently working on such a document. Keep posted to the JDeveloper OTN website http://otn.oracle.com/products/jdev for updates on this.

Advantages of using Oracle JVM over JPDA for Remote Debugging?

What are the "additional features" that the documentation hints at when using the Oracle JVM for remote debugging vs. the JPDA protocoL? Can a member of the JDEV briefly address this? What exactly am I losing when using JPDA?

I am not getting anywhere with 'NCOMPing' the stuff. Attempts to NCOMP keeps erroring out . The first of the errors is
'Error while determining classes contained in jsch-1.29_minimalClassListAndTCD

Kuassi, I have looked at a few of your posts where you make mention of a file titled 'Settings_os.properties'. I see no such file in my Oracle installation. What am I missing here ?

How to use Remote Debugging in JDeveloper 3.1 ?

I am trying to use the Remote Debugging option with EJBs in JDeveloper 3.1 with Oracle8i 8.1.6.
I checking all steps the online walkthrough for Remote Debugging EJB in 8i and it didn't work.
I'm using Oracle8i EJB/CORBA debug option in project properties, but it does not stop in my EJB's break points.
I tried deploying the EJB again ( with break points) and again it didn't work.
The error message I got in the trace file is:
Errors in file D:\Oracle\admin\SCT\udump\sctS000.TRC:
ORA-29516: Aurora assertion failure: Java thread deadlock detected
Could someone please tell me how to use it?
null

Which platform is the database running on ??
Other things you should check -
when debugging the EJB, JDev
3.1 looks through your IIOP connections to find the one to use.
Make sure that the IIOP connection that JDev is using for the debugging matches the IIOP connection that the EJB client application is using.

Need Urgent Help in remote debugging

Folks!
Im having difficulties remote debugging my application.
Im using jdev rc2 using oc4j 9.0.2 externally on a win2k machine.
My sources are compiled outside jdeveloper using the oracle compiler.
Ive setup the server to run with: d:\oradev\jdk1.3\bin\java -ojvm -XXdebug,port4000 -jar oc4j.jar
After compiling the sources on my own, i deploy them. Then i mark a breakpoint in Jdeveloper and debug the source with the breakpoint. The debugger connect properly ( both server and jdev confirms ).
I trigger the flow which should reach my breakpoint, it runs and doesn't stop.
When i tried debugging something which i had compiled in jdev it worked under the same setting.
Any ideas?
any kind of help would be appreciated.
Yuval.

You can get good summary of checklist from this article about
DBA checklist for data warehousing.
Which highlights on below pointers:
New system or old. (I.e. Up-gradation vs starting from scratch)
Complexity of SQL Server architecture
SQL Server storage
Determining SQL Server processing power
SQL Server installation consideration
SQL Server configuration parameter
SQL Server security
SQL Server Database property
SQL Server jobs and automation
Protecting SQL Server data
SQL Server health monitoring and check ups
SQL Server ownership and control
based on my real time experience, I will suggest you to keep an eye on
Load performance (It will be useful when your database(Warehouse) will have huge amount of data)
System availability (Check for Windows update and up time configuration)
Deployment methodology should be planned in advance. Development of packages and respective objects should be done systematically.
Source control mechanism
Disk space and memory usage
You might or might not have full rights on production environment, so be prepared to analyze production environment via Select statements [I guess you got my point]
Proper implementation of Landing , Staging and Mart tables.
Column size (this can drastically decrease your database size)
Usage of indexes (Index are good, but at what cost?)
I hope this will assist you in building your check list.

Jdeveloper remote debugging - Unable to find source error message

Hi,
I am trying to remote debug a simple Java application (non-web) using Jdeveloper. The Jdev debugger can connect to the remote debuggee, but unfortunately it throws me a message saying: 'Unable to find source file'. As a result, if I ignore this message, it simply ignores my source breakpoints.
Can anybody please help with any tips?
My project source is checked out from CVS and does not follow a conventional source path as such.
Thanks,

Step Over not working with Remote Debugging of Servlets with JRUN

Platform: JRun 4, JDK 1.4.1, JDev 9.0.3
using JPDA and copied jpda.jar to JDEV_HOME/java1.2/jre/lib/ext and set path to jar in app server path.
using debug args: java.args=-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5000
ok, I'm able to attach JDeveloper to JRun and remotely debug by jumping from breakpoint to breakpoint but stepover causes JDeveloper to continue execution to completion or to next breakpoint. Any idea why step over does not work? The only way to halt execution during remote debugging is by using breakpoints.
Thanks in advance for any insight to this issue.

Hi Bob,
I think OTN ate the other thread. It says there are 4 replies, but it won't display them. Here's my latest reply.
I just noticed something interesting from your original message. You say you are using JDK 1.4.1 for the app server (that's good) and you are using JDev 903. But you say you have copied jpda.jar to JDEV_HOME\java1.2. That doesn't make sense because JDev 903 didn't have a java1.2 directory; I think JDev 903 has a jdk directory which contains JDK 1.3 (actually 1.3.1_03 or something like that).
Also, jpda.jar is really old and the directions for using jpda.jar and for putting jpda\bin on the app server path is really old. Those directions were needed for JDK 1.2 because JPDA was released AFTER the JDK 1.2 was released. Starting with JDK 1.3, jpda is built in and you don't need the jdpa.jar or the jpda\bin, etc.
All this reminds me that in JDK 1.2, HotSpot had bugs where stepping didn't work!!! I'm almost positive that this is what you are experiencing. Here is my advice:
1. Make absolutely sure that you are using JDK 1.4.1 (or at least JDK 1.3 or later) for running your app server. Make sure that you are not using JDK 1.2 - you may have modified your app server so that it uses JDEV_HOME\java1.2\bin\java.exe[i]Long postings are being truncated to ~1 kB at this time.

Remote debugging in OC4J using JDeveloper

I need to remote debug into a stand-alone OC4J using JDeveloper 10.1.3.1.0. The documentation says the following:
In the <jdev_install>/jdev/lib directory, copy ojc.jar and jdev-remote.jar to <OC4J_HOME>/home/lib.
I can't find directory "<OC4J_HOME>/home/lib" in the stand-alone OC4J? That is, a "home" directory does not exist in the above location. To where should I copy ojc.jar and jdev-remote.jar ?
Thanks,
Travis

Shay,
JDeveloper gives an error when deploying my EJB after starting an OC4J for debugging. In contrast, JDeveloper does successfully deploy my EJB if I start OC4J using "D:\jdev10131\jdev\bin\start_oc4j.bat".
Note that I'm able to start my standalone OC4J successfully after setting the following in a command window:
1. Start a Microsoft Windows command window.
2. set JAVA_HOME=D:\jdev10131\jdk
3. java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000 -jar oc4j.jar
Below is the the deployment error that JDeveloper gives when deploying my EJB to the debug OC4J. At the bottom it mentions something about "javac.exe not found". Do you know how to fix this?
