select MAX(A.VALUE) AS HIGHEST_OPEN_CUR,p.value as max_open_cur FROM V$SESSTAT A, V$STATNAME B, V$PARAMETER P
WHERE A.STATISTIC# = B.STATISTIC#
AND B.NAME = 'opened cursors current'
AND P.NAME = 'open_cursors'
GROUP BY P.VALUE;
的结果为29X
是否一到300就会发生ORA-O1000：m~imum open CUrsOrs exceeded 错误，还是会内部进行一些cursor的释放？
另外通过
SELECT A.VALUE, S.USERNAME, S.SID, S.SERIAL# ,b.name
FROM V$SESSTAT A, V$STATNAME B, V$SESSION S
WHERE A.STATISTIC# = B.STATISTIC#
AND S.SID = A.SID
AND B.NAME = 'opened cursors current';
查到了那个sid
但
select * from v$open_cursor
where sid=上面的sid
的数量不一致的，是什么原因？
