DTR - While writing to a network socket an unexpected Exception occured.

[Former Member]

Hi,

I am running into an error while trying to access (Checkin or release activities or trying to access thru browser).

Here is the content from the trace from trace log(defaultTrace.trc)

#1.5#0014C257BD0B00580000005D00000B0400041DE8C6FC90ED#1158785514632#com.sap.engine.services.servlets_jsp.client.RequestInfoServer#sap.com/tc_dtrenterpriseapp#com.sap.engine.services.servlets_jsp.client.RequestInfoServer#Administrator#1359####d935c08048e911dbc4560014c257bd0b#SAPEngine_Application_Thread[impl:3]_35##0#0#Error##Plain###Processing HTTP request to servlet [DTRServlet] finished with error.

Hi,

Have you been able to solve this problem? I have the same issue.

I have the same error. I am on NW 7.0 Support pack 9.

I did try to restart the service mentioned but that did not help.

Here is the error when we try to go to the DTR

500 Internal Server Error

SAP J2EE Engine/7.00

Application error occurred during request processing.

Details: Error [javax.servlet.ServletException: WebdavServlet.init() failed : com.tssap.dtr.pvc.repository.InitializationException: CentralServer could not setup a new serverSocket. Port=55,615], with root cause [com.tssap.dtr.pvc.repository.InitializationException: CentralServer could not setup a new serverSocket. Port=55,615].

Exception id: [001CC4B7985600710000016C00003FAD000454C205EC0EB9]

I verified that nothing is running on port 55615 by doing 2 commands on unix...

We had a issue with this server over the weekend and the applications went down hard... I have tried to stop and restart the NWDI and everything is working except the DTR?

let me know if you have any other ideas.

thanks,

Deidre Logan

Hi Deidre,

Details: Error javax.servlet.ServletException: WebdavServlet.init() failed : com.tssap.dtr.pvc.repository.InitializationException: CentralServer could not setup a new serverSocket. Port=55,615, with root cause com.tssap.dtr.pvc.repository.InitializationException: CentralServer could not setup a new serverSocket. Port=55,615.

I believe your problem is related to the note

#833998 -- DTR does not initialize because of port 50013

Hi,

There are two options to fix up this problem.

<b>Option-1</b>

Upgrade to:

Support package 16 if you are on release 6.40

Support package 07 if you are on release 7.00

<b>Option-2</b>: (if option-1 is not possible)

On the J2EE node on which the DTR application is failing, re-start the DTR application. To do this, open the Visual Administrator' and then in Server->Services->Deploy, choose the 'Application' radio button.

Locate the application 'sap.com/tc_dtrenterpriseapp' and click on 'Stop Application' to stop the application. Select the node on which the DTR application is failing and choose 'OK'. To restart the application, click on 'Start Application' and select the stopped node and choose 'OK'

Hope this solves the problem.
