In SAP HANA index server and statistics server stopped suddenly and not running.
I tried to stop and restart the server by the following commands.
HDB stop
HDB start
But still it is not working. Does anyone know what causes this problem and what is the solution? Thanks in advance.
If the indexserver doesn't start, you cannot logon as SYSTEM (or any other user for that matter). A good way to find out what the reason for the failed start is to check the tracefile for the nameserver, the indexserver and the statisticsserver.
Logon as <sid>adm and change to the tracefile folder via cdtrace.
Then find the tracefiles and use e.g. less to read through them to find the actual error messages.
Alternatively you can use SAP HANA Studio with the emergency connection to review the trace files without terminal access.
