Hi experts,
I tried to make a backup using dbmcli but I have the following error: -24991,ERR_NODBSESSION: no databse session available
Can you help me?
thanks in advance!

Sure, but it would be better if you'd help yourself ...
Did you check the documentation?
Why don't you just use the GUI tools instead of fiddling around with the dbmcli?

Lars

No, you haven't - at least not properly: backup_start|http://maxdb.sap.com/doc/7_7/39/e89fe68c0f46ad888b055a9f11cb23/content.htm]:
You would have found this instead:
Prerequisites
- You have the server authorization Backup.
- You have opened a database session (see: db_create *dbconnect*_ ).
- If you want to perform an interactive log backup, you must have performed a data backup for the relevant database at least once.
....
You need to have a database session to run backup_start !
Therefore: use db_connect before you use backup_start.
Also have a look at the WIKI: [HowTo - SAP MaxDB backup with Database Manager CLI|http://wiki.sdn.sap.com/wiki/display/MaxDB/HowTo-SAPMaxDBbackupwithDatabaseManagerCLI]
