Oracle设置最大游标数

 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
  Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

  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
