brconnect warning CRITICAL_FILE

Hello guys,

When I run a database check (brconnect), I get the following warning message:

Database administration alert - level: WARNING, type: CRITICAL_FILE, object: /oracle/PRD/sapdata3/prd640_11/prd640.data11, value: (max_size) 8192000 KB (> 8126128 KB)

My question is, where is set max_size parameter??? where can I check it?

When I do select to the following tables: dba_data_files, dba_tablespaces, but I can't find the value shown in the warning message.

I think that value is set with the statement 'create datafile....', but how do I find it in a administration view or table???

Thanks for your help
