Hi Technology consultants,
I installed ECC6.0 SR3 with MaxDB7.6 on AIX6.1 (ABAP). After updating the kernel path level 179,
the database startup failed, i tried to revert back to the old kernel same issue again it showing.

The database is not coming to ADMIN mode.
Anybody plz give a solution.
Thanks and Regards,

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.

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

plz give me a solution for this issue.
Thanks and Regards,

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>
