Hi All,

we are executing a Data Services extraction job that reads from a SAP on MaxDB.

The job ends with the following error:

[SAP AG][SDBODBC DLL][MaxDB] General error;-10807 Connection down: [3] command timeout

from the transaction sap DB59 the errors present are as follows: Communication Timeout - Command Timeout

what is the cause? how can the problem be solved?

Thanks and Best Regards

Hi Davide,

Here is the return code explanation:

The connection to the database instance was terminated. This error can occur if, for example, the database instance was shut down, or if there are network problems.<description> provides the internal error number and further information about the error.
User Response
Check the connection data. Check whether the database instance is ONLINE. If it is online, log on to the database instance again using the SQLDBC_Connection::connect method.

Besides above, do you have network firewall which will kill the network connection after certain threshold reached?

If note of above helps, please attach diagpack.tgz maxdb trace after executing command:

dbmcli -d <dbsid> -u superdba,<password> diag_pack

Best regards,

Dear James,

our problem was due to default timeout for the database user.

Db session could need several minutes in ETL environment.

By extending the maxDB user timeout we avoided the error.

Thank you so much.
