Hi experts,
Two of my HANA services have been facing some issues you may help me solve. As I'm new at hana, I don't know why they started failing.
Below is a screenshot of my services status.
- I've tried to restart webdispatcher service but i get the following error code: "SAP DBTech JDBC: [2]: general error: service or host or port is not found"
Looking at my trace files I can see the following logs:
webdispatcher_alert_mo-fd98c3e5f.30006.000

- I also tried restarting my instance with root user through ssh with no success.
Any help will be greatly appreciated!
