1、查看Oracle最大游标数
  C:\Documents and Settings\Administrator>sqlplus "sys/admin@test151 as sysdba" (sys以dba登录test151服务)
  SQL*Plus: Release 9.2.0.1.0 - Production on 星期四 11月 5 09:08:04 2009

  连接到:
  Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production
  With the Partitioning, OLAP and Oracle Data Mining options
  JServer Release 9.2.0.1.0 - Production
  SQL> show parameter open_cursors;
  NAME TYPE VALUE
  ------------------------------------ ----------- -------------------
  open_cursors integer 300

  2、查看当前打开的游标数目
  SQL> select count(*) from v$open_cursor;
  COUNT(*)
  ----------
  17494
  3、修改Oracle最大游标数
  SQL> alter system set open_cursors=1000 scope=both;
  系统已更改。
  SQL> show parameter open_cursors;
  NAME TYPE VALUE
  ------------------------------------ ----------- --------------------
  open_cursors integer 1000
