MaxDB doesnu00B4t start

Hello I´ve got a problem:

Last week i´ve installed an IDES ERP 2005 on MaxDB.

So far all worked well for a view days. Yesterday we had to restart the server because it got more phys. memory.

We stopped the SAP System via SAP MMC, then put the DB in offline mode via MAXDB Database MAnager Gui, then stopped the still running services.

Server reboot.

When i wanted to connect to the database via DBMGUI there is an error. I click on "connect db" then entered the user and password (surely correct). Then nothing... DBMGUI works and works until i get the message "programm is not responding". When i look into the taskmanager dbmsrv is running at about 50% cpu usage but the kernel doesn´t load.

So i killed dbmgui, restartet the whole server (after 3 hours waiting for connect) and tried to start the db via dbmcli.

Same error... dbmsrv runs and runs and runs but the kernel does nothing. Where can i find a hint in the logs? Are there logs?

What maybe the problem? How you see MAXDB is not my cup of tea, i usually use oracle, this is our first system with maxdb.

Thanks for your help, points are guaranted

You are getting memory write errors. Have you tried restarting the system without the new memory?

Just a thought...

DB doesnt start

Hi Benjamin,

I can't see direct reason for your problem in the files but there are some points which are looking very strange as for example „RTE Database tries automatic restart“. It looks like that for further investigation a system access is badly needed and highly probable a debugging of the dbmserver. Have you already open an OSS message?

Hello,

you can check first what it logged in the knldiag file which is located in the rundirectory usually like /sapdb/data/wrk/<DB-SID> If the file knldiag was not created you can check whether some error messages are logged to the file dbm.prt

Could you execute some dbmcli commands without connect to the database for example "dbmcli db_enum"?

Best regards,
