Cannot Start ABAPTrial NW 7.52 System

[nikos_c]

Hello!

I have installed the SAP Netweaver 7.52 trial system. Everything worked fine, but suddenly, the system cannot start.

I used the startsap ALL and stopsap ALL commands, but the disp+work dispatcher is grayed out.

I have an openSUSE installation.

Additionally, below you may find my dev_w0 log file:

Hi,

The root cause is seen in the dev_w0 trace:

M *** ERROR => ThSetGwParam : NiHostToAddr vhcalnplci.dummy.nodomain failed

SAP is configured to use this hostname, and Linux cannot find its IP address (neither in the "/etc/hosts" file nor in a DNS lookup).

Indeed, I added the aforementioned FQDN in the hosts file and it worked!

Thank you.

Hello,

Thank you for the quick reply.

I tried pinging the server via IP address and also via the hostname and it reply correctly in both pings.

I have set the DNS in the linux - because otherwise I couldn't reach the internet.

Maybe this is was might have cause the issue.

I am really puzzled. I really cannot find the solution to the issue!

Hi Nikos

After installing the SAP trail have you change the hostname? or if the host does not have to DNS resolution from the hostname and IP? try to ping the hostname and IP address
