Hello Zuo,

Is the problem solved ?

[matthias_hollstein]

Hello
We have the same issue with SLES 15 SP02

Cannot process an HTTP request to servlet [DTRServlet] in [dtr] web application.
[EXCEPTION]
javax.servlet.ServletException: WebdavServlet.init() failed : com.tssap.dtr.pvc.repository.InitializationException: Gave up on waiting for the response for request id=1 after 5,000 milliseconds.

with that issue, we are not able to activate NWDI on this Server

[ben_zuo]

Thanks ,

New Install the SUSE15 ,if the package "net-tools-deprecated" installed ,the dtr can start.

Maybe ,this is Bug?

[former_member247835]

Thanks for the hint, installing the net-tools-deprecated package solves the problem.

Hi ben_zuo,

Is this after your migration to SLES15 or a new Installation setup, what is your NW version. Could you give us the details of your OS version, use below

cat /etc/os-release

In case of migrated you might, require to use the old hostname in correspondance to the new host-IP address & reboot the server & retry

Thanks,

Kaushik

Hi ben_zuo,

To reply to my answer, you can use the Comments button as it would put in Threads & nicely managed way for other readers as well.

Coming back to your actual question, There are still many uncertainties on SLES15 yet to be tested from SAP side. You can check the SAP Note: 2369910 for your OS compatibity. If its a new install, my suggestion would be to still use SP within SLES12

Thanks,

Kaushik
