20090 check knldiag kernel exited with '0' before reaching admin state

[MarcelWolf]

Hello,

when i'm trying to start the database on my Linux machine i'm getting the following error:

Trying to start database...

Log file: /home/ewmadm/startdb.log

Databse start failed

DB startup failed

In the startdb.log:

-24994,ERR_RTE: Runtime environment error

20090 check knldiag kernel exited with '0' before reaching admin state

In the KnlMsg i can't find any obvious errors.

Hello Marcel,

you need to check why the kernel exited.

For this logfile

- knldiag (for MaxDB Version lower than 7.7 ) at /sapdb/data/wrk/<SID>

- or KnlMsg (for MaxDB Version 7.7. or higher) at /sapdb/<SID>/data/wrk/<SID>

needs to be checked.

You may add it here to this conversation.

Hi Marcel,

The issue seems to be with permission for your user id. So request you to have look on below oss notes:-

1283278 - Database cannot be started

1976254 - Start problem with McAfee antivirus

Also do provide us with the latest /sapdb/data/wrk/<SID>/ knldiag log files.

Unfortunately the knldiag File is not there...

With "find -iname knldiag" in the / directory it can't be found either only the KnlMsg there.

Yes i checked the Notes.

A McAfee Antivirus is not installed on the System.

When i try to do the command "dbmcli -d EWM -U w show state" the output is:

OK
