Problems starting SAP server on Linux

[rainer_fux2]

Hello,

We have installed our SAP ERP 6.0 on linux (suse 10) x86_64 without any problems, and it worked fine. But after trying to stop and restart the server, it fails. We did it with:

stopsap

startsap

The error messages in the logs are these:

trc file: "CPICTRC25768", trc level: 1, release: "700"

The dispatcher log files are not showing any errors.

But there are other messages like partner nod reached, connection refused etc.

We already checked the hosts and services files. Seems all to be okay. We replaced the kernel files with the newest one, and we checked the memory parameters, but as well all seems to be okay.

Any ideas, why the dispatcher always crashes?

hello,

Your system is listening to the port number GWSERV=3372

Can you check the port is active (netstat -a or netstat -an |grep 3372)

And have you maintained Services and hosts file entries correctly, in /etc/hosts and /etc/services.

Regards

JUDE.

Hello Jude,

Thanks for your reply.

Already checked your propositions.

1. netstat :

netstat -an |grep 3372

reading dev_w0 either the log is not complete or the WP never fully started... can you post dev_disp?

Can you check if the gateway port is blocked by another resource?

You can do that with command netstat -an |grep LISTEN. Gatewayport is 33<systemnumber>
