Oracle can use yast to enable EM to manage the system. The yast packages are available from http://oss.oracle.com/projects/yast/

http://www.ss64.com/orasyntax/plus_set.html

you can use the SPOOL command to save the output into file and send it directly to the printer, for file follow the instruction:

SQL>SPOOL filename

SQL>select yada yada yada;

SQL>SPOOL OFF

The virtual tables are stored in memory and start with V$ and there are a bunch of them as follows:

select VIEW_NAME from ALL_VIEWS WHERE (view_name like ‘V_$%’ or view_name like ‘V$%’) order by view_name;
