Thank you SS.
You are right. After the License key installation it took longer to restart the server. After long time I was able to connect. But then the dump appear as mentioned in my second comments.
After spending and a long research it has been found that the problem was (may be) because of the JVM version. I reinstall the JVM and then restart the SAP server. Then after the log on the dump did not appear.
Thank you SS for your support.
Best Regards
