.NET server not running .

[Former Member]

Hi All,

I'm trying to run my dotnet iview in the browser and I am getting the error as .net server is not running .I am using EP6 SP9.Also the .net server and the portal server are installed on different machines.

The iViewProcessorService configuration values are:

NET Runtime Engine Servers Configuration=<.net server ip address>:8050

Enable Ja.NET Log=false

Lease Time=5

Portal Servers Configuration=<portal ip address>:8051

Request Timeout=15000

Thanx,

Rohit

Hi,

An obvious questions first - Did you start the NT service?

Assuming yes, can you tell me more about the servers you use (2K,XP,2K3?). mostly I'm asking about where you have the .NET installed. Also you should make sure your firewall (and server) settings allow you to use the two ports you use in your configuration (8050, 8051).

Thanks,

Hi,

I am using windows 2k professional for the servers.How can I check my server and firewall settings ,if they allow me to use the ports (8050,8051)in my configuration.

Thanks,

Hi,

Try talking to your IT...

The .NET server (NT service) uses TCP/IP to communicate with the J2EE portal. They listen on ports (8050 and 8051, each use 1 port). Sometimes firewalls and some severs (like 2003) block TCP communication on some ports. So you first should make sure these ports are available. If not you can either change the port they use (see configuration guide) to a port that your IT opens for you or simply ask your IT to open these ports.

Hi Ofer,

Thanks and regards,

Hi Ofer,

Once again I'm facing the same problem. Recently I changed my machine and I installed everything once again. And now I am getting the same error as .net server not running. I tried many combination of port numbers, but couldn't fix it. Also IT guys told me that these ports are free(not blocked).

please provide some clue to fix it.

Hi,

make sure that you updated the ip of the new machine (which runs the .NET Runtime component) in property of the service in the portal.

Also note that you must restart the portal service and runtime server after you do any changes in the settings.

Hi,

I did the same,but to no use. I am still getting the error "Problems occured while trying to connect to .NET server..NET server is not running" while viewing the component in browser. Also with the netstat command in command prompt, I can see .net server port listening to the portal server and vice versa.

Hi Rohit,

Can you tell me what is written to the log by the service,

(just increase the severity of the logging messages of the service using the Visual Admin).

What is the OS of the machine that runs the portal? What is the portal SP? what version of the PDK are you using?

Hi,

"Only one usage of each socket address (protocol/network address/port)is normally permitted" - it mean that your port is not available - try to use a different one.

Hi,

Thats right but the problem is whenever I try to change the port no. in ep.exe.config and epsrv.exe.config files, Itdoesn't show the message that the server is running instead I get this message :

Hi,

1.If you can see this message in the portal iView - it mean that your the Portal and the .NET server communicate just fine ! but we still need to resolve the Mutex problem.

2 Please try to process "Hello World" sample before running your own portal component.

3.Did you made any changes at the "PortalApps" folder?

4.Can you run .net "WebApplication" on your machine?

Regards,

Yehuda

Hi Yehuda,

For now I am trying "Hello World" only. And I didn't make any change in "PortalApps". And my .net WebApplications are running fine.

Hi Rohit,

The mutex problem can occur when two process of the same .net server are running - the console application and the NT service in the same time ,please ensure that just one of the process is running.

I also offer you to switch on the .NET Logger in the portal - from the Visual Administration go to Log configurator under Location com\sap\portal\dotnet change the severity to All and run the Hello World component and send me the all the log's of com.sap.portal.dotnet.

Hi Rohit,

BTW

you can use this tool to discover if the port is available - <u>http://www.download.com/3000-2085-10062969.html?part=65960%2520&subj=dlpage&tag=button</u>

Sorry for not responding for a long time as I was busy with some other work. Anyway I have installed patch2 of PDK.NET and things are working fine now.

Thanks for all your helps.
