Multiple Remote Debug Sessions

I have a feeling that I know the answer but will ask anyway. Is there any way to set up WebAS so that more than one developer can have a remote debug session at the same time? All of the documentation that I have seen on http://help.sap.com implies that it is one debug session per Java instance. I would like to know if you can set up more than one simultaneous debug session on the same instance.
My guess is no since each developer needs a port to connect to. Is that true?
Thanks,
Steve

As for a I know your guess is correct and the answer is 'no'. The reason is that the debug port is under control of the java vm, not the java application. And it looks like the vm closes the TCP listening port as soon as a single connection has been established. Only after the connection is closed, the vm reopens the listening port.
The problem is probably at the OS process level itself; if two remote debuggers took control over one process and one issued a stop while the other asks the process to continue then it's for both debuggers pretty undeterministic in what state the process is running now.

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.

WD Java Remote Debug problem: Release Process from debugging

Hi Community,
when I used to debug Web Dynpro Java from the SAP Developer Studio (eclipse) to a remote host (Portal AS NW Java), it works fine for the first run. After disconnecting the remote debug session (server0), I changed the coding and try to debug again with the effect that the old coding is still used from the server process (server0) even though the parameter "Create and Deploy archive" is set (enabled) in the debug configuration. Furthermore the funktionality of "Relase process from debugging" option in the J2EE Engine dosn't react / work.
I think that the debug session is still running and the Developer Studio is not able to send any "Kill" statement to the server process for ending this session.
I tried following:
A. Rebuild Project and Deploy the archive on the "normal" way
B. Reopen the Developer Studio itself
C. Start the Project in debugmode again and chose the option "Terminate All"
...all without any success.
The only way is to restart the whole server process server0 again with the same trouble after the first debug.
Did any of you have a clue or experience to clear or kill the debugsession from the process so that next debugsessions can be started, please reply.
Thanks

Remote debugging with APEX and SQL Developer

Hi,
I have problems concerning breakpoints within my SQL Packages I want to debug.
I want to force SQL-Developer to suspend execution of a function, so I can get forward step by step.
The SQL-Developer do not stop executing at the breakpoints I set in the Package.
The message I get is the following (on SQL-Developer side):
Debugger accepted connection from remote process on port 4000.
Processing 110 classes that have already been prepared...
Finished processing prepared classes.
Debugger disconnected from remote process.
Seems to me, that the process runs into the debug-mode but leave without stopping at a given breakpoint??
Do anybody have an idea how to solve it?
We use Oracle 10.2.0.3.0, SQL Developer 1.5.1 and APEX 3.1.2.
The Package-function I want to debug runs on another Oracle database as the APEX application.
Thanks in advance
Regards
Norbert

Hi Carsten,
now I have done a further step. I can debug a remote PL/SQL-Package through APEX, but now I get an exception when the program execution jumps back to the APEX PL/SQL-Package.
My APEX-Page-Process looks like this:
BEGIN
dbms_debug_jdwp.connect_tcp(host => 'IP-ADDRESS', port => '4201');
APEX_TEST_PKG.remoteDebug;
dbms_debug_jdwp.disconnect;
END;The procedure APEX_TEST_PKG.remoteDebug looks like this (located on the APEX-DB):
PROCEDURE startRemoteDebug
AS
    v_string    VARCHAR2(50)   := '';
BEGIN
    [email protected](host => 'IP-ADDRESS', port => '4000',
             option_flags => dbms_debug_jdwp.connect_defer_suspension);
    v_string := [email protected];
    DBMS_OUTPUT.PUT_LINE(v_string);
    [email protected];
END remoteDebug; The procedure REMOTE_TEST_PKG.testFunc looks like this (located on the Remote-DB):
FUNCTION testFunc RETURN VARCHAR2
AS
    v_string    VARCHAR2(50)   := '';
BEGIN
    v_string := 'Test';
RETURN v_string;
END testFunc; When I start the debug session without the option dbms_debug_jdwp.connect_defer_suspension, I get an exception Oracle.EXCEPTION_ORA_604.
Starting the debug session with the above mentioned option, I am able to debug the remote function.
But now I get an exception when the executor tries leaving the remote function going back to the invoking function. With the debugger I can step over the return-statment successfully and the debugger steps on the next line END testFunc;. On this line I get the exception above
Exception breakpoint occurred at line -1 of PBREAK.pls.
$Oracle.Builtin.EXCEPTION_USER:
Exception breakpoint occurred at line -1 of PBREAK.pls.
$Oracle.Builtin.EXCEPTION_USER: I tried another way where I get now exception and where I can step through my functions in APEX, descending to functions in the remote db and going back to APEX.
For this case I put the debug-statements in remote function:
FUNCTION testFunc RETURN VARCHAR2
AS
    v_string    VARCHAR2(50)   := '';
BEGIN
    dbms_debug_jdwp.connect_tcp(host => 'IP-ADDRESS', port => '4000');
    v_string := 'Test';
    dbms_debug_jdwp.disconnect;
RETURN v_string;
END testFunc; But I have no idea why it doesn't work properly starting the remote debug session in the apex procedure.
Regards
Michael

SQL Developer Hangs when connecting for Remote Debug

Hello,
I've been trying to use the Remote Debug feature of SQL Developer. We are writing a Web Application that connects to Oracle and I would like to debug a package function on the database server (which is not the same machine as my SQL Developer client).
To test my configuration, I tried connecting on SQLPlus creating a connection (by calling exec dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', 'xxxxx'); ) and calling a function which had a breakpoint and the debugging started immediately on SQL Developer. Then I tried putting the dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', 'xxxxx'); call inside the stored procedure I was debugging (prior to the line with the breakpoint) and it connected and got to the breakpoint successfully as well. So I'm pretty sure my firewall / user privileges are set up correctly.
So I modified the function that my web application eventually calls to create the connection (in order to remain in the same session) but whenever it gets to the connect_tcp line SQL Developer hangs and I'm unable to debug. I've realized that it only hangs if I have a breakpoint there. If I don't have a breakpoint then it creates a connection just fine. Of course without a breakpoint it's a bit difficult to debug isn't it? :)
My Sql Developer version is 3.0 and I'm connecting to Oracle 11.1.0 Below you can find a dump when running SqlDeveloper with console. My OS is windows XP and my Oracle instance is running on Linux.
I appreciate any help you can provide.

What I mean is that I put the connect_tcp command inside the package function I want to debug in order to ensure it's going to remain in the same session. e.g.:
Function GetValue Return Varchar2 Is
Begin
dbms_debug_jdwp.connect_tcp('xxx.xxx.xxx.xxx', '25255');
return 'My Value';
End;
I'm afraid I cannot post our code which causes this problem due to our information security policies and simple console and web applications failed to replicate the problem. The function creates a connection to Oracle SQL Developer (which can be seen in the environment with the small ladybug icon) if no breakpoints are set which obviously doesn't allow breaking into the function. However if a breakpoint is also specified in the Return line the connection seems to freeze Oracle SQL Developer. No ladybug icon is shown and no Remote Debug Session seems to open.

Remote debugging

Is it possible to set up IFS to enable remote debugging?
I'd like to be able to attach JDeveloper debugger to the IFS JVM.
I run IFS on a remote machine.
Thanks,
Roman

Roman,
Have you checked the online help in Jdeveloper there is a lot of information on remote debugging.
If you use 1.1 you should check the following which I've copied from the online help:
Configuring Apache JServ for Remote Debugging Java Server Pages
If you are using Apache Jserv, you can debug using either the Oracle Java Virtual Machine (JVM) debugging protocol or the Sun Java Platform Debugging Architecture (JPDA). When you start your remote debugging session, you will have to choose which method to use. Depending on which one you choose, your configuration options are a little different.
Using Oracle's JVM
To use Oracle's JVM debugging protocol, you'll need to change the JVM that Apache JServ uses, modify the parameters you send to the JVM, and modify the CLASSPATH for Apache JServ.
These changes must be made on the computer that is hosting Apache JServ. If you do not have permission to make these changes, talk with your administrator.
Changing the JVM
In the jserv.properties file, set the wrapper.bin parameter to the full path of the JDeveloper JVM (java.exe). For example,
wrapper.bin=C:\Program Files\jdeveloper\java1.2\bin\java.exe
Setting parameters
In jserv.properties, set the wrapper.bin parameter to
wrapper.bin.parameters=-XXdebugondemandquietport4000
The -XXdebug parameter options are the following:
ondemand
Start the java program right away and allow a debugger to connect any time. Without this option, the Java program stays halted until a debugger is connected.
port4000
Debugger must connect at the specified port. Without this option, the port is 4000.
quiet
Don't print connection messages. Without this option, connection messages are sent to standard error.
Changing the ApJServerAction entry
In jserv.conf comment out any existing ApJServAction .jsp entries by putting a # at the beginning of the line.]
#ApJServAction .jsp /servlets/org.gjt.jsp.JSPServlet
Add a new ApJServAction .jsp entry
ApJServAction .jsp /servlets/oracle.jsp.JspServlet
Adding servlet init parameters
In the servlet init parameters section of the zone.properties file, add the following lines.
servlet.oracle.jsp.JspServlet.initArgs=emit_debuginfo=true
servlet.oracle.jsp.JspServlet.initArgs=jspcompiler=oracle.jdeveloper.jsp.JspOjcCompiler
servlet.oracle.jsp.JspServlet.initArgs=classpath=C:\Program Files\Oracle\JDeveloper\java1.2\jre\lib\rt.jar
Setting the CLASSPATH
In jserv.properties, set wrapper.classpath to
wrapper.classpath=C:\Program Files\Oracle\JDeveloper\jswdk-1.0\lib\servlet.jar
Make sure that the location of ApacheJServ.jar is specified.
wrapper.classpath=C:\Program Files\Apache JServ\ApacheJServ.jar
Comment out the location of jsdk.jar.
#wrapper.classpath=C:\jsdk2.0\lib\jsdk.jar
Using JPDA
To use JPDA debugging protocol, you'll need to modify the parameters you send to the JVM, tell the server how to find the JDPA library, and modify the CLASSPATH for Apache JServ.
These changes must be made on the computer that is hosting Apache JServ. If you do not have permission to make these changes, talk with your administrator.
Setting parameters
In jserv.properties, set the wrapper.bin parameter to
wrapper.bin.parameters=-classic -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000 -Xdebug -Xnoagent -Djava.compiler=NONE
To see the invocation options for JPDA, see Sun VM Invocation Options.
If you are running on Solaris, you may also need to include stdalloc=y as part of the -Xrunjdwp paramater, like the following:
wrapper.bin.parameters=-classic -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=4000,stdalloc=y -Xdebug -Xnoagent -Djava.compiler=NONE
Adding the JPDA library
In jserv.properties, set wrapper.path to include the location of jdwp.dll. This file is is part of the Java Platform Debugging Architecture.
wrapper.path=D:\jpda\bin
If Apache JServ is running on Unix,
setenv LD_LIBRARY_PATH /home/jpda/lib/sparc:$LD_LIBRARY_PATH
setenv PATH /home/jpda/bin:$PATH
where home/jpda is the path to your JPDA installation. In addition, you will have to pass that environment variable through Apache to the JVM. To do that, in jserv.properties, add the following line:
wrapper.env.copy=LD_LIBRARY_PATH
Setting the CLASSPATH
In jserv.properties, set wrapper.classpath to
wrapper.classpath=C:\Program Files\Oracle\JDeveloper\jswdk-1.0\lib\servlet.jar
Make sure that the location of ApacheJServ.jar is specified.
wrapper.classpath=C:\Program Files\Apache JServ\ApacheJServ.jar
Comment out the location of jsdk.jar.
#wrapper.classpath=C:\jsdk2.0\lib\jsdk.jar
Let me know if this helps

Remote debugging through NAT - VS2013, C#

I need help figuring out how to initiate a remote debugging session when the target computer is across the internet and behind NAT. VS2013 and a C# application, .net 4.5
Remote debugging works great here on my LAN, but now I need to connect to a remote stand alone (not on a domain) PC that is behind NAT; it's WAN IP is different from its LAN IP. My development PC is also behind NAT. I do not have access to the
remote firewall/router to configure port forwarding. Is there any other way I can connect? Are there any tools that will allow me to connect directly to the remote PC with the remote debugger, similar to how TeamViewer can connect to PC's even
though they're behind NAT?

Hi Matt_FL,
Like this document here:
http://www.codeproject.com/Tips/618804/Remote-debugging-for-Visual-Studio-from-different
It shared us the detailed steps about how we setup the remote debugging if the Environments are not in the same domain.
So I'm afraid that we would check whether the Environments meet the requirements of remote debugging.
Reference:
https://msdn.microsoft.com/en-us/library/vstudio/bt727f1t%28v=vs.100%29.aspx?f=255&MSPPError=-2147217396#bkmk_setuptheremotecomputer
If the remote computer is protected by a firewall, you must configure the firewall to allow the Remote Debugging Monitor to communicate with the Visual Studio host computer.
If your network requires that communication be performed using IPSec, you must open additional ports in the firewall.
If you are debugging a process on a web server, you must open an additional port.
Other threads I met before:

https://social.msdn.microsoft.com/Forums/vstudio/en-US/897782e5-dada-4df1-8ef2-f119cdce7e5e/remote-debugging-over-internetMaybe
you could refer to them, hope it could provide useful information.
But as far as I know, we could remote debugging with WAN even if it has some specific requirements.

Remote debug a Flash file running inside an application

Hello everyone.
I'm an application developer, and my standard usage of Flash is as follows:
I'm creating an executable application, which contains a ShockwaveFlash object instance, which in turn is displaying a Flash Movie Clip - also created by myself. The executable application and the contained Flash clip are communicating via the ActionScript ExternalInterface (using XML strings) and the FSCommand.
I'd like to be able to debug the ActionScript code of the Flash file while I'm running/debugging my executable application. For that, I need to be able to start a remote debugging session from the Flash object running inside my executable. Problem is, I did not find any way of doing this.
When I publish the Flash SWF file with "permit debugging" checked, I'm able to start a remote debugging session when I'm displaying the file in a player or a browser (the "debugging" option is shown at the right-click menu of the Flash object), but I'm not able to do the same with the object inside my executable (the "debugging" option doesn't exist on the menu).
Environment Details:
The executable application is using the ShockwaveFlash COM file to create the ShockwaveFlash object.
The executable application is created using VB.NET, Visual Studio 2008, .NET 3.5.
The Flash SWF file is created using Adobe Flash Professional CS4.
I'm developing under Windows XP (SP3).
Any bits of information will be much appreciated!
M.A. Hanin

I'm not sure how to do specifically what you are looking for (if possible at all.....)
But, I recommend checking out deMonsterDebugger. It is an AIR application with some classes for use. You simply import the classes into your Flash project, instantiate a debugger object, and then compile.
If you open the AIR application when the SWF is running (locally, in a browser, and I imagine in another application) the AIR application serves as a debugging engine, similar to the in-Flash debugging.
There is a bit more to it than that, but I think that this is your best bet for what you are looking for.

Remote Debug on Portable

I know Flash CS5 has the ability to debug applications remotely, I was wondering if this is possible with just Flash Builder ?

Debugging a swf that has gone through the Packager for iPhone and converted
to IPA.
When you compile the IPA you have the option for ipa-debug. When the app is
opened, you are prompted for an ip address of the machine you are debuging
on. In Flash CS5 you'd go to Debug > Begin Remote Debug Session > AS 3.0
and you'd see all traces and what nots.
Just wondering if possible in Flash Builder.

Remote debug midlets w/ WTK 2.1

Hi,
i am encountering strange problems when trying to remote debug a MIDlet.
I started the WTK emulator with ANT with correct settings. I connect my IDE
in a remote Debug session to the Emulator. The emulator receives the
connect and starts the application.
So far, everything is fine. But when i set breakpoints, the MIDlet wont stop. I
dont get any information in my debugger, other than "session connected".
No Frameinfo or any other stack messages.
Anyone allready tried that and succeeded?

I have been having a similar problem. Have you tried setting a breakpoint on the very first line in your application immediately inside the Midlet subclasses' constructor and seeing if the application will break there?
I find that my remote debugger (IntelliJ) can connect and it will break very early on in the program, but as I travel through the program either by stepping or running, the debug session will hang at some random place - generally failrly early in the application. I usually only get a couple of methods into the program before the debugging gives up, so this might cause the effect you were seeing.
I'm not sure of the fix yet - I was thinking of trying increasing the memory on the emulator and if that doesn't work then using Eclipse as the remote debugger. What IDE are you using?

How to enable remote debugging for a session other than the current one

Hi all,
I am trying to figure out how to enable remote debugging for a session other than the one I am currently using.
More specifically, we have an application that is making database calls to Oracle 11gR2. Something is causing an exception during this invocation. My system is currently not set up to recompile said application, so I can't just add the debug call to the code and recompile. Therefore I would like to be able to log into the database (as sys, if necessary) and invoke dbms_debug_jdwp.connect_tcp on the desired session.
The docs indicate that I should be able to do so:
dbms_debug_jdwp.connect_tcp(
host IN VARCHAR2,
port IN VARCHAR2,
session_id IN PLS_INTEGER := NULL,
session_serial IN PLS_INTEGER := NULL,
debug_role IN VARCHAR2 := NULL,
debug_role_pwd IN VARCHAR2 := NULL,
option_flags IN PLS_INTEGER := 0,
extensions_cmd_set IN PLS_INTEGER := 128);
But when I try (even as sys), I get the following:
exec dbms_debug_jdwp.connect_tcp('1.2.3.4',5678,<session id>,<session serial>);ORA-00022: invalid session ID; access denied
ORA-06512: at "SYS.DBMS_DEBUG_JDWP", line 68
ORA-06512: at line 1
00022. 00000 - "invalid session ID; access denied"
*Cause: Either the session specified does not exist or the caller
does not have the privilege to access it.
*Action: Specify a valid session ID that you have privilege to access,
that is either you own it or you have the CHANGE_USER privilege.
I've tried granting the 'BECOME USER' privilege for the relevant users, but that didn't help. I read something about having to set some kind of ACL as of 11gR1, but the reference documentation was very confusing.
Would someone be able to point me in the right direction? Is this even possible, or did I misread the documentation?

Interesting deduction, that would be very useful indeed. I hate recompiling just to add the debug call, and it can't be done in our production environment. But it seems unlikely to me it would be implemented this way.
I would cross-post this in the SQL AND PL/SQL forum though, as this is really a database issue, not with the SQL Developer tool. Do add the links to the other posts in each.
Regards,
K.

Problem sharing remote tooltalk session by multiple users

I need advice on how to create a remote tooltalk session and have it shared by multiple users. Currently, I have a few remote ttsessions, but I'm running into with TTauthority to let others share those same sessions. Is there any way to have a common tooltalk session which would support a dynamic number of users?

I'm running into issues with Tooltalk's security
mechanism ttauth. I need help to setup up a main
session (one MIT Magic Cookie) which would be shared
by mulitple users. The problems are occuring with new
MIT Magic Cookies being generated per new user login.
I have tried the extract and merge approach to get
other users' information, but this has proved to be
an inefficient way for applications to communicate
with each other. Please help!

Multiple remote sessions to same machine

Hi everybody,
is there a way to allow on Leopard multiple remote graphical logins? I would like to connect to my account using VNC or ARD remotely while a user is logged in locally. Is it possible to do that without a third party software? If a third party sw is necessary what would you suggest?
Thanks in advance for any help,
Paolo

Hello,
All data is sent to all replicas that need the data at the rate at which they can consume. So to answer your question, no because it doesn't care where the replicas are it just needs to get it the data. What you could do is put some type of compression wan
accelerator on each end but the data stream by default is already compressed with availability groups so I'm not sure how much extra help that may give.
If you want to verify this out for yourself, packet capture the mirroring endpoint setup for AOAG on every replica.

Can 1 instance of Windows 8.1 ENTERPRISE host multiple Remote Desktop connections?

I am shopping for the components for building a machine with fair, high-performance hardware. I have Windows 8.1 Professional. I wanted to know if either Windows 8.1 Professional or Windows 8.1 Enterprise can support multiple remote connections
from users outside the local network. For example, my brother is based in San Diego, CA and has an underpowered laptop. Is there any way to make a remote connection over that much distance, from San Diego to Northern Virginia, from a RDP client running Windows
8.1 Professional to a RDP "server" Windows 8.1 Professional/Enterprise machine, and run a modern, single- or multiplayer- game over smoothly that connection? At the very least, is it possible to run common
apps (e.g. Microsoft Office 2013 IE 11, Adobe Acrobat XI) smoothly on a Windows 8.1 Pro RDP client connected to a Windows 8.1 RDP "server" located 2250+ miles away?
Would upgrading my installation from Professional to Enterprise improve the responsiveness and display quality for my remote users?
I know Windows Server R2 2012 has features specific for handling remote connections, but I am trying to keep a Windows 8.1 user experience. Still, if anyone can show some evidence that Windows Server 2012 R2 Remote Desktop Services (RDS) improves display
and responsiveness over long-distances for remote (RDS) connections, then I will shop for Windows Server 2012 R2 Standard instead. The huge drawback of Windows Server 2012 R2 Standard CALs is the enormous cost to enable 3-5
remote connections for family, non-commercial use.
Has anyone attempted to host long-distance remote access, non-commercially, for 3-5 connections? Has it worked well? What, in general, is required?
T. Webster

Hi,
It depends on the quality of the network connection to run the software smoothly throuth RDP. And I don't think the quality would be better if you upgrade to Windows 8.1 Enterprise.
Windows 8.1 allow only one session of RDP, the Remote Desktop Server in Windows other than the Windows Server edition has a limitation to allow only one concurrent user per session by default, i.e. if someone remotely connects to the computer over RDP then
whoever was logged in at that moment will be automatically logged off, even if that user is physically present at the computer. This is by design.
Regarding more information about RDP, please take a look at the following articles:

If I created the VM as Generation 2 I am able to start the VM but the RemoteFX adaptor doesn’t appear in the device manager. I have read generation 2 isn’t compatible with RemoteFX.
VM2 – *Testing purposes* - Windows 8.1 Enterprise configured as generation 1 that is fully patched.
This VM I am able to start up and run the VDI after the RemoteFX video adaptor is installed, also the correct adaptor appears in the device manager. This seems to at least work correctly but I cannot pinch and zoom and the experience is poor.
GPU summary within the Hyper V settings state there are 4 physical GPU’s all of which can be used with RemoteFX and that 1 virtual machine are using the GPU (Windows 8.1 enterprise VM)
Firewalls off, latest RDP clients
I have read you should be able to use Windows 2012 R2 and we should be able to use the sessions with pinch and zoom but now and then you come across something that tells me different.
Question 2 – I need this to work with Windows 2012 R2 so we can use Remote Desktop Sessions
and the tablets can use pinch and zoom, anyone tell me what I may be doing wrong?

Hi,
Thank you for posting in Windows Server Forum.
As per my research, you need to run the command although video adapter is disabled on motherboard. If you install the RemoteFX cap driver, the integrated video adapter is disabled while the operating system is running.
For more information you can refer beneath article.
1. RemoteFX (with Hyper-V) is a serious business tool. For games.
2. Configure RemoteFX in Hyper-V running Windows Server 2012 with low end GPU
Hope it helps!
Thanks.
