Hi,

It is possible that there is some conflicts in the version of the programs that is calling the DB from SAP because of Kernel Upgrade.

Please reboot your server on OS level and give a try again.

I would suggest FIRST checking the cause of the error and then, if necessary, reboot. This is a Unix system which usually never needs to be rebooted (as opposed to Windows).

Those two things (kernel update + failed database start) are totally not related.

Please check the kernel diag files (knldiag, knldiag.err).

Hi Markus,

I checked these log files knldiag, knldiag.err and knltrace. I that knldiad.err log showing

2009-05-26 17:26:32 1 ERR 11872 MEMORY Not enough memory for I/O buffer cache wanted : 1397760 kB!

2009-05-26 17:26:32 0 ERR 12006 DBCRASH Kernel exited without core and exit status 0x200

1 ERR 8 RTEMem No more system pages for 8192 bytes available,BYTE_SIZE=4096,DESCRIPTION=valloc,ERRORTEXT=ENOMEM ? out of memory

I think this is memory problem, i given swap size 12GB and ulimit is

devserv:ardadm 1> ulimit -a

time(seconds) unlimited

file(blocks) unlimited

data(kbytes) 131072

stack(kbytes) 4194304

memory(kbytes) 32768

coredump(blocks) 2097151

nofiles(descriptors) 2000

threads(per process) unlimited

processes(per user) unlimited

plz give me a solution for this issue.

Thanks and Regards,

srinivas.

Check

Note 487972 - Operating system parameterization of liveCache

This is for the livecache but applies also for MaxDB.

Hi Markus,

Sorry for the delay. In MaxDB where can i set database parameters. Somebody told T-code db50 u can set the parameters, but mine is not connecting to database. Still i am facing same problem for production server also.

dbprod:arpadm 13> dbmcli -d ARP -u control,arkkays09 db_warm

ERR

-24994,ERR_RTE: Runtime environment error

1,Check knldiag! Kernel exited with '0' before reaching ADMIN state (OS error code 11000)

After Installation what are the parameters we have to set for MaxDB7.6.

Give me solution for this issue.

Thanks and Regards,

srinivas.

You can use DB-Studio or DBMGUI, both downloadable at

http://service.sap.com/swcenter-3pmain

--> MaxDB and SAP DB

The other option is on command line using

dbmcli -U c param_directput <parameter> <value>
