The Job Server is not responding (Designer can't run jobs)

[Former Member]

Hello everyone,

The architecture is the following: Linux SAP DS server installation on virtual machine and client Designer in local Windows 7.

When trying to change the environment designer communication ports, it gives the error Job Server is not responding.

Here is a list of things which I checked:

• I can ping linux VM server from windows host (ping 192.168.56.101)
• I can ping the windows host from linux VM server (ping 192.168.56.1)
• I can telnet the linux job server on port 3500 from the windows host side (telnet 192.168.56.101)
• Inbound & Outbound port rules added to the windows host: 40000-65535
• ICMPv4 Inbound and outbound windows firewall host rules added for communication on all ports
• linux server iptables default config set to accept any connection for which it does not find in the rules:
  • Chain INPUT (policy ACCEPT), Chain            FORWARD (policy ACCEPT), Chain OUTPUT (policy ACCEPT)

              there is also in the rules(-A INPUT -p icmp -j ACCEPT,-A FORWARD -p icmp -j ACCEPT)

Wireshark(network sniffer) shows that there is an issue  of communication between the designer and server:

Communication must be open in both directions. Is port 3510 open on the DS client? Can you telnet that port from the Linux server?

Indeed I can't telnet the client/host on port 3510 from the server, although I can ping it. I have made both an inbound and outbound rule for this port(and also rebooted) on the client/host side.

I am not sure now how to solve this network issue?

I have tried to connnect with the designer using another newly created job server listening on port 3333. However the same exact issue is still there.

It seems that the telnet service is running since i can connect with telnet localhost 8080 on the server.

The problem is not in the client-server connection, but in the opposite direction, server to client. The server cannot communicate wit hthe client, port 3510 is not open.

I have added a inbound and outbound rule though for the port 3510 and even thereafter a rule to open up all ports, also ICMPv4. Also on linux side the port 3500 is listening

I can access the CMC and the managment console from the windows host

Also I am using wireshark(network analysis): it mentions some problems though, but for which I do not understand because as mentioned above everything should be set up correctly.

Hi,

Uncheck this option in your DS Designer:

and specify the port range (i.e: 3510 - 3510 ) add this ports in your firewall rules and test again, after restart the SAP DS Designer.

Also add the server host in you Host File.

I have added the server host to my host file; bodsvm => 192.168.56.101

However when trying to uncheck the option about the range of communication I get the error:

[former_member198540]

please check the following:

1. Make sure oyur user account in client machine have admin rights.

2. Use telnet commnand on client machine to be sure that you have correct comunication between Client - Server machine. Its the test cant counicate, maybe disable the windows firewall in client machine.

3. specify the CMS request port in CMC console like this:

4. Check this KBA for more info about ports issue with DS Designer: 1416303
