Hi Sumit,

Check also this SAP note: 1036371. It may be the reason for the issue you are facing now.

Hello Dessiree and Jonas.

Many Thanks for replies.

Java link http://<host>:<port>/ wasnu2019t responding but strange! It was opening the page http://<host>/index.html

Per the help link http://help.sap.com/saphelp_nw2004s/helpdata/en/39/16b7401711cc38e10000000a155106/frameset.htm

From note 1036371 I checked the value of parameter Port of Dispatcheru2019s http provider service which was set to

Port:80,SocketQueue:200,AcceptingThreadsCount:10,BindAddress:,Type:http)(Port:443,SocketQueue:200,AcceptingThreadsCount:10,BindAddress:,Type:ssl)

I Added : (Port:50000,SocketQueue:200,AcceptingThreadsCount:10,BindAddress:,Type:http) to the value and link with port also started working.

Issue Resolved.

Many Thanks Guys 

Hi Sumit,

If the Java stack is not even writing logs in the work directory, it is possible that the profile parameters are lost. Please check note 741289 and ensure that all the relevant parameters are correctly set. Then try to restart.

Hi Sumit,

if you can't open the main page of the application server try another one, like http://<host>:<port>/NWA or http://<host>:<port>/useradmin. If these also fail or doesn't show anything you should verify if the system is configured correctly, maybe there are few threads or not enough memory. Check this note:

723909 - Java VM settings for J2EE 6.40/7.0

To verify the number of threads of the system you should stat the configtool and navigate to Global Server Configuration in the right vertical panel -> Expand the managers entry -> Select ApplicationThreadManager -> the value of MaxThreadCount property should be around 250 (or 350 if you are using XI).

Still on the configtool -> Select ThreadManager -> here the value of MaxThreadCount property should be around 150.

If the values are not ok, change them, save and restart the J2EE Engine. The lack of threads for the system and application usually cause this kind of problem and also can degradate the startup time and perfomance of the system.

Let us know if this helps.
