Answer 1

That means there is two cursor related parameters
                                        |
                                        |
                                        |
                                        |
                    |                                        |     
1)Cached cursors                              2)Currently open cursor
1)Cached cursors     2)Currently open cursor
SQL> select o.sid,osuser,machine,count(*) num_curs
from v$open_cursor o,v$session s
WHERE user_name = 'ERP' and
o.sid = s.sid GROUP BY o.sid,osuser,machine
ORDER BY num_curs DESC;     SQL>select max(a.value) as highest_open_cur,
     p.value as max_open_cur
     from v$sesstat a, v$statname b, v$parameter p
     where a.statistic# = b.statistic#
     and b.name = 'opened cursors current'
     and p.name= 'open_cursors'group by p.value;
THIS IS THE RESULT I GOT
SID OSUSER MACHINE NUM_CURS
106 x 18
93 x 14
124 x 14
152 x 13
90 y y 11
121 z 8
132 a 8
118 b b 6
105 c 5
131 b 5
98 d d 4
95 x 3
147 y y 3
89 e 2
119 e 2     THIS IS THE RESULT I GOT
HIGHEST_OPEN_CUR MAX_OPEN_CUR
83 500
     -This is related to ORA-01000 -MAX CURSOR EXCEEDS
From the above what I understood is correct ???
F) How to clear 1)Cached cursors ? (or) how to reduce NUM_CURS (from the above left side table ).
G) will the 1)Cached cursors give any problems to our database.
