Kernel died before reaching ADMIN state (OS error code 11000)

[Former Member]

Hi All,

I am trying to install MaxDB 7.6 on AIX 5.3 using SAPinst for Content Server.

But at the final stage the db start fails with the following error

-24994,ERR_RTE: Runtime environment error

1,Check knldiag! Kernel died before reaching ADMIN state (OS error code 11000)

I checked the knldiag which shows me the following messages

RTEMem Error 8

No more system pages for 1065353216 bytes available,BYTE_SIZE=4096,DESCRIPTION=valloc,ERRORTEXT=ENOMEM ? out of memory

In addition there is a warning message that

maximum heap size: 128 MB

WNG 12447 MEMORY memory size needed exceeds heap size!

At the end of the file the message is

Not enough memory for I/O buffer cache wanted : 1040384 kB!

Can somebody help me setting the correct memory parameters for successful start of MAXDB.

The main memory of the server is 2 GB.

Thanks in advance

Hi Murali,

the error messages say it all:

- the maximum heap memory that is allowed to be allocated by processes of the sdb-user is 128MB

- your database cache alone should be 1016 MB...

So I would guess that you did not configure the os limitations correctly. Doublecheck the setup using the

ulimits

tool.

See note <a href="https://service.sap.com/~form/handler?_APP=01100107900000000342&_EVENT=REDIR&_NNUM=628131&_NLANG=E">#628131 - SAP DB / MaxDB operating system parameters on Unix</a> for further details.

Hi Lars,

Thanks for the info

I increased the memory limits to 1.5Gb from 128MB and the db started.
