Problem when using HDB start / stop the HANA Server Express, NiPGetServInfoError

[Former Member]

Problem happened when I use the HDB to start / stop the HANA Server, but it works well when I used the HANA studio.

The /etc/hosts has defined for the "localhost"

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

When I run the Start Server command in debug mode: /usr/sap/HXE/SYS/exe/hdb/sapcontrol -debug -prot NI_HTTP -nr 00 -function Start

And I failed to add the "xs_worker" role to the host

The following error can be found in the xscontroller_0.log:

Hi Mike, after I commented the ipv6 ip "::1" in the /etc/hosts file, the problem solved, but I don't know why...

[MikePaola]

Glad your problem was resolved - I believe it's looking for an ipv4 address.

Hi Mike,

The xscontroller cannot start due to that problem. There is no tenant database in that server yet, therefore, there is no index server.

Here is the screen capture

Thanks,

Hi Ching -you mention things work with HANA Studio. If you have the HANA server up and running, verify all the processes are there by doing an "HDB info" from a command prompt. After that, let me know if you can do an "HDB stop" followed by an "HDB start".
