livecache cannot be started
I cannot start livecache (7.7.07.50 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
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.
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!
