hdbdaemon HDB Daemon not running due to nameserver.ini missing or deleted

 

You try to start HANA DB from the command line with 'HDB Start' and an error returns 'FAIL: process hdbdaemon HDB Daemon not running'.

Possible Reason:

1. The nameserver.ini file is corrupt 

2. The nameserver.ini file is missing, the error messages in the nameserver trace files:
    [75956]{-1}[-1/-1] 2020-02-21 16:24:16.302707 f NameServer TREXNameServer.cpp(02829) :     [landscape]/master is missing in nameserver.ini. did someone delete SYS/global/hdb/custom/config/nameserver.ini ? -> stopping instance ...
 [75956]{-1}[-1/-1] 2020-02-21 16:24:16.312673 e Basis TREXNameServer.cpp(02859) : Process exited due to an error via explicit exit call with exit code 1 , no crash dump will be written

Solution :

 

Check the nameserver.ini  file if there any nameserver entry in that file if no maintain manually below the entry.

Open a text editor and copy the following text into the file and save it as nameserver.ini
 

[landscape]

 id = 

master = 

worker = 

active_master =

The id for your system is located in the landscape.id file: Location of file: [...]/hana/SID/data/mnt0001/hdb00001/landscape.id

open landscape.id get ID

 
For master = hostname: port number (single node system)

worker= hostname

active master= hostname: port number (single node system)

Default locations of the nameserver.ini file:

[...]/global/hdb/custom/config/nameserver.ini [...]/exe/linuxx86_64/HDB_1.00.67.383230_1263754/config/nameserver.ini

Note: The HANA configuration file files (nameserver.ini, indexserver.ini, xsengine.ini, etc.) are not backed up as part of a database backup.
