I’ve searched the forums and tried various suggestions – all to no avail. My issue is that Websphere 7.0 will not start in Debug mode. The issue is with dt_socket not being able to be loaded. Here’s my native_stderr.log:

<JIT: FullSpeedDebug: ignoring countString>
<JIT: FullSpeedDebug: ignoring countString>
09:04:46.674 ERROR: [TransportManager.cpp:138] Loading of dt_socket failed
09:04:46.674 ERROR: [Agent.cpp:164] JDWP error in VM_INIT: TransportException [509/0] Loading of dt_socket failed

What I do think is this: I was running a server as an application. I created a 2nd server as a Windows service. The service will debug, the app will not. Creating a new profile as an app and the issue remains. So somehow, when you make a profile as a service, something changes the environment. Removing the profile that was a service (and removing the service from Windows) does not remedy the issue.

Anyone else experience this? We’ve had several developers at my company have this happen to them as well.

After spending hours on it, on a whim I copied the Websphere dt_socket.dll into the Windows\system32 directory. Lo and behold, I can now debug the profile as an application. This comes after trying things like making the directories of Websphere and My Eclipse Blue completely writable. Also finding every instance of dt_socket.dll on my hard drive and making sure it was readable and not in the path before Websphere.

Now the question is WHY did this work?

Ed,

Sorry that you were seeing issues.

Can you please let us know if the installed MyEclipse, WAS and default JVM are 32 bit or 64 bit versions to help us investigate further?

[Ed Morris]

All 64-bit. Also, a friend of mine found this post below. I tried it – it also works.

Hi all,

My system is windows7 64 bit and I am using MyEclipse blue edition 10.7.1. I am trying to run websphere server in debug mode but it is not running. It shows me icon of debug the server also starts but on updating the server the server status it shows run mode and it runs in run mode rather than debug mode.It is not Starting in debug mode.I have tried the solution of copying dt_socket.dll file in the system 32 directory.But still it is not working.

Please tell me possible solution for it.
