SQL & PL/SQL

hi experts

Can you help with some problems please?

1.) I try to run shell script from dbms_scheduler, which runs sqlplus and the output of sqlplus commands is written to file using command spool. To this point everything is running ok.
My problem is, that output of this file is: (e.g.)


SQL> PROMPT ****************USERB******************
****************USERB******************

SQL> --SELECT sid
SQL> -- FROM v
SQL> -- WHERE audsid = SYS_CONTEXT('userenv','sessionid');


But I don't want the whole first line in the output file. I only want the output of this command, like on the second line.

2.) How Can I write two outputs from sqlplus using command spool running at the same time into one file?
Like in first issue described above. The main sqlplus create a job and this execute the background sqlplus using shell script. But both, the main and the background sqlplus are written to output file at the same time. But only one is written into. But I want the both outputs in the file.
How Can I do that, if I can?

Thanks a lot.
