    One way:

    alter database backup controlfile to trace;

    Go find the trace file in your udump (if specified) directory and open it.

    Thank you very much for your answer. I thought there was some sql to check these values directly from sqlplus.

    Okay, another way, but the results are harder to interpret:

    Code:
    select TYPE,RECORDS_TOTAL from v$controlfile_record_section;
    
    TYPE              RECORDS_TOTAL
    ----------------- -------------
    DATABASE                      1
