HANA xsengine & daemon nolonger starts after a database restore

Hi ,

Post HANA database restore (from a backup of the same system taken an hour before) system, daemon & xsengine stopped working. While starting the services I'm getting the below errors.

SAP DBTech JDBC: [2]: general error: service or host or port is not found

SAP DBTech JDBC: [2]: general error: service or host or port is not found

All other services are up and running. Please let me know if anyone has faced such issue in the past.

Regards,

    Hi All,

    This issue is resolved. I found the below entries in 'daemon_production.30000.000.trc'.

    [72706]{-1}[-1/-1] 2014-12-10 16:58:05.673837 i Network TrexDaemon.cpp(02186) : cannot bind socket to 127.0.0.1:30000: Address already in use (98)

    [72706]{-1}[-1/-1] 2014-12-10 16:58:05.673864 e Network TrexDaemon.cpp(02192) : cannot listen on socket to 127.0.0.1:30000: Address already in use (98)

    [72706]{-1}[-1/-1] 2014-12-10 16:58:05.673896 i Network TrexDaemon.cpp(02186) : cannot bind socket to 127.0.0.2:30000: Address already in use (98)

    [72706]{-1}[-1/-1] 2014-12-10 16:58:05.673904 e Network TrexDaemon.cpp(02192) : cannot listen on socket to 127.0.0.2:30000: Address already in use (98)

    [72706]{-1}[-1/-1] 2014-12-10 16:58:05.673913 e Network TrexDaemon.cpp(02141) : cannot listen on bound socket to *:30000: Address already in use (98)

    The port 30000 was already used by the daemon process of the instance started before restore. A clean restart whould have helpedb, but I was unable to stop the HANA server processes through HDB stop as the daemon process itself was not running. The only way was to kill all the process & stop all services.

    I tried killing all the processes manually from HANA studio -->Administration consolre --> Landscape--> Services by right clicking individual processes and choosing 'Stop' or 'Kill' but thay will start automatically almost immediately.

    Then I've done the below to stop/ kill all the processes at a single go.

    loggied in to <sid>adm

    pp1adm >kill -9 -1

    It immediately killed all the processes of HANA & no processes starts automatically.

    Started HANA with HDB start command from pp1adm.

    All the processes are now up after system comes up.

    Regards,

    Asutosh.
