livecache cannot be started

Hello experts,

I cannot start livecache ( on Linux) due to following errors:

dbmcli on LCD>db_online


-24994,ERR_RTE: Runtime environment error

20090,Check knldiag! Kernel exited with '1' before reaching ADMIN state

The database is in state "offline", but resources were found: pid file

found but

startup message from kernel:Core dump suppressed

dbmcli on LCD>show state


No root pointer in mapping table

'RTECons_MemoryDumpMapping' instance could not be created

Failed to map memory dump files

I have tried to clear pids from below files (by mv LCD LCD.old) and then start.



Cleared shared memory by:

/sapdb/LCD/db/pgm/dbmshm CHECK /var/lib/sdb/dbm/ipc LCD

/sapdb/LCD/db/pgm/dbmshm DELETE /var/lib/sdb/dbm/ipc LCD

I have also tried to delete folder /sapdb/data/wrk/LCD/rtedump_dir and

checked SAPNote 1283278.

Attached is knlmsg log.

Thank you for any advice.

Hi James,

based on SAP Notes I found out there was different number of data volumes and log volumes present on the server than in configuration. Command param_getvolsall showed 13 data volumes and 1 log volume but there were 21 data volumes and 2 log volumes on server. It means that by restore_param i "took away" data volumes from number 14. I reverted it as I described above.

I have opened OSS message to SAP and they solved the issue. The cause was that parameters MirroredLogVolumeName002 and LogVolumeName002 were identical. So I set parameter MirroredLogVolumeName002  to different path than LogVolumeName002.

Thanks a lot for help!
